$0.00
Introduction

Second Generation 150 MHz Technology – Moisture and Hectoliter Weight/Test Weight in 10 seconds.

The Aquamatic 5200 is Perten’s second-generation high frequency moisture meter. Drawing on the experience from more than 5,000 installed units, we have designed a moisture meter improved in every aspect – accuracy, repeatability, reliability, and user interface. It can be a stand-alone moisture meter for use at terminals or can be integrated into automated testing systems

Higher frequencies provide greater penetration of samples; the updated UGMA provides a more accurate result regardless of temperature or crop type; the improved mechanism provides better repeatability. Together this makes the AM 5200 the most accurate and repeatable moisture meter available. It can analyze grains, oilseeds, pulses, beans, lentils, seeds and more for moisture, Test Weight/Hectoliter Weight, and temperature.

Features and benefits
  • Superior accuracy – Save money by paying the right price for the grain you buy
  • Moisture and Specific Weight – Save time with one instrument for two measurements
  • 10-second analysis – Save time and costs
  • Touch screen operation – Easier to use with fewer mistakes
Features and benefits

The Aquamatic 5200 utilizes new, advanced technology to bring benefits to you.

Superior Accuracy

Superior accuracy and repeatability are obtained using 150 MHz measurement cell made of robust, high precision die-cast aluminum. The new cell is slightly larger providing a more representative sample.

Rapid Analysis

Just pour the sample and the AM 5200 begins analysis automatically. Results are displayed in less than 10 seconds. An optional flow-through provides for automated testing when the sample can be discarded.

Modern Technology

Using higher frequency, advanced computational power, USB data transfer, and the updated UGMA, the AM 5200 is designed for today’s grain trade.

Accurate Results on Fresh Field Samples

Older moisture meters read up to 1% low in moisture when analyzing grain straight from the field (known as the rebound effect). The higher frequency measurement employed by the AM 5200 penetrates deeper into the grain providing more accurate results and shorter return of investment.

Easy To Use

The large color touch screen with intuitive user interface makes the AM 5200 simple to use. Input sample IDs, view results on a remote screen, and update through USB memory sticks all add to its flexibility and ease of use. The touchscreen uses resistance technology and will even respond to gloved hands.

Operation and handling

A moisture meter has to be easy to use, and what could be simpler than
just selecting the product to be analyzed and then pouring the sample into the instrument?

At Perten Instruments we have always taken pride in developing analyzers that are so easy to use that they can be used confidently by non-technical personnel. The Aquamatic 5200 follows the tradition and can be used by anyone after just a 1-minute introduction. Three simple steps is all it takes.

Select grain type on the touch screen Pour the sample. The analysis will start automatically. After ten seconds the results are displayed on the screen, and you can emtpy the sample box.
Easy To Use

The Aquamatic 5200, like all Perten models, was designed to be easy to use. As seasonal workers are often used at grain receivals, it’s important that the equipment they use is as simple to operate as possible. This decreases introduction and training time, and minimizes handling errors.

Printing results

For an immediate receipt of results, the Aquamatic 5200 can be equipped with an optional ticket printer.

Data Transfer

The Aquamatic 5200 can be connected to a computer for easy transfer of analytical results into business systems or office applications. You can either collect analytical results in real-time into a LIMS, or download results from the internal memory to a USB memory stick at your convenience.

Superior design

 

Quality, Reliability, Excellent Support for an Amazing Price. It all comes together in the best package from Perten Instruments.
Solid Foundation

It’s all about quality. The AM 5200-A is made of heavy metal sheeting and Delrin. The build quality extends instrument life and reduces damage potential during relocation and shipping. It weighs 45 lbs.for a reason.

Measurement Cell & PC Board

The single piece cast cell ensures accurate measurements of volume/density through precise control of cell dimensions. The RF electronics are built directly into the cell center divide eliminating cabling and removes impedance matching issues over time due to connector degradation.

Superior Temperature Sensing

A continuous strip of copper (6.8in2) makes contact with hundreds of kernels for a precise sample temperature measurement over a wide temperature range. The large area/low mass means quick response times when there is a large disparity between room temperature and grain temperature, down to -40F. It means better accuracy and shorter analysis times.

Motor

A single, high quality motor is used in the AM 5200-A. The simplicity of design leads to a longer instrument life and less down-time.

Auto-Analysis Mode

Our greater than 7 year experience has resulted in an optimized analysis procedure in this 2nd generation instrument. Select the product once, and the instrument automatically begins analysis each time a sample is poured into the hopper. Not only does it speed up the analysis, it saves wear on the touchscreen.

 Lower Cell Door

The door employs a self-cleaning firm “snap action” close and is gravity driven. The “snap action” is designed to shake loose any build-up of material on the lower door. You can be confident the cell volume will not change due to dust build-up resulting in erroneous weight and volume measurements.

Sample Strike-off

The sample strike-off is critical to controlling flow of product through the instrument. Our design minimizes debris build-up in the instrument. Grain is not sprayed throughout the interior. The AM 5200-A uses 3 brushes to direct grain to the collection drawer.

 Connectivity

The AM 5200-A has configurable data output using USB or RS-232 connections. Our Plug and play functionality mimics GAC© systems output for immediate replacement into existing scale software, LIMS, etc. An optional printer is available.

Technology

The Aquamatic 5200 is easy to use, but don’t let its apparent simplicity deceive you. It is the most advanced grain moisture meter available, and utilizes advanced technology to provide rapid and accurate results.

How does a moisture meter work?

Just about all bench top moisture meters use what is often referred to as the capacitive method or RF dielectric method. With this method a radio signal at a specified frequency is sent through the sample. As water interacts with radio waves (that’s how your microwave oven works) it is possible to determine the moisture content by measuring how much the radio signal is changed by the sample.

The effect that the sample has on the radio signal is termed the dielectric constant, and it increases proportionally to the moisture content. There are a number of other factors that have an effect on the dielectric constant, perhaps most notably sample density and temperature. These two factors are measured and corrected for in advanced moisture meters.

150 MHz technology improves accuracy

Up until a few years ago moisture meters have used a radio signal with a frequency between 1-15 MHz. This is an area which is easy to work with as moisture has a strong signal there and electronic components have been available off the shelf for a long time. The problem is that there is a lot of noise, so the signal to noise ratio for moisture is poor, decreasing the accuracy of the moisture measurement and creating the need for frequent calibration updates, and
for specific calibrations for the different classes within a grain.

For example, older moisture meters often have to use several calibrations for wheat and barley, one per class. Another problem of older technology was the “rebound effect”, where the instrument would read too low when analyzing grain straight from the field. The reason was the lower radio frequencies would not penetrate the kernels, so the instrument would only see the surface moisture content.

In the USDA study quite some effort was spent on finding the optimal frequency. Measurements were done from 1 MHZ to over 200 MHz, and the results very clearly showed that the accuracy was much better at 150 MHz than the old 1-15 MHz range. At 150 MHz the noise is much lower and the signal is much more specific to moisture. The overall effect is that the shortcomings of the previous technologies are eliminated in a 150 MHz system. The sensitivity to kernel moisture distribution, grain variety, crop year and geographic location is much lower, and the performance will thus be significantly better.

UMA - one calibration for all products

Another important USDA development was the new UMA (Unified Moisture Algorithm) calibration technique. It further improves the accuracy and makes it possible to use one and the same calibration for all grains and oilseeds. There are three main components in the UMA – a new type of sample density correction, the use of a 4th order polynomial equation, and a new way to adjust for sample temperature effects.

A density correction is done in most advanced grain moisture meters. As written above, density has
an effect on the dielectric constant and in order to achieve good accuracy it is necessary to determine the density and adjust for it when calculating the moisture content. What is new in the UMA is the equation by which the density correction is calculated. The new density correction equation creates an almost perfect correlation between the dielectric constant of a sample and its moisture content. It is also an important factor behind the ability of the UMA to use one calibration for all grain types.

The 4th order polynomial equation, which is the actual calibration, is a more advanced mathematical technique than what is used in previous moisture meters. This is possible thanks to the higher processing power of the Aquamatic, which uses modern computing technology.

The effects of sample temperature has always been a difficulty for moisture meters, but with the introduction of UMA this is no longer a problem. The UMA uses a new algorithm for moisture correction which adapts the adjustment to the moisture content of the sample. The right adjustment for a cold wet sample is not the same as for a cold dry sample, and the UMA handles that with very good results.

Applications and Performance

The Aquamatic 5200 determines moisture, specific weight and temperature in all kinds of grains and oilseeds. It sets new standards among grain moisture meters when it comes to accuracy, stability and transferability.

Accuracy

The Aquamatic is probably the most accurate grain moisture meter available. In a recent evaluation performed on samples from GIPSA (US Grain Inspection) the performance of the Aquamatic was excellent. 230 samples of nine grain and oilseed types were analyzed, and the average standard error versus the oven reference method was only 0.20. The graph is presented below.

 

No temperature effect

Thanks to the UMA calibration technique there is no effect of the sample temperature in the Aquamatic 5200. The graph below shows the results from a test of the Aquamatic where the same three samples were analyzed at cold, medium and warm temperatures. Each square represents one analysis, and the three samples were analyzed from 50F (10C) to 100F (35C). As is evident from the graph, the Aquamatic gives the correct results regardless of the temperature a sample is analyzed at.

Transferability

All Aquamatic units are alike. If you would place two units side by side and analyze the same sample in both of them, you would get the same result. This comes partly from using the 150 MHz technology, and partly from the advanced standardization procedures we have developed. Below is a graph from a group of 7 instruments after being standardized. The same set of 6 samples (2 wheat samples, 1 corn, 1 soybean, 1 sunflower seed and 1 rice sample) ranging from 8.5-13.5% moisture was analyzed in all 7 Aquamatics. In the graph it is hard to make out the dots for the individual units as they are on top of each other, which is good because it means that all units gave almost exactly the same result when analyzing the same sample.

Perten – Inframatic 8800 NIR Grain Analyzer

$0.00
Introduction

IM 8800 is the next generation portable NIR instrument for protein, moisture and oil determination in grain and oilseed.

The instrument has been designed with portability in mind to give users freedom to measure grain in-field, at grain storage sites and at grain processing locations. Equipped with GPS enables point specific sampling to generate protein maps on-the-go to make informed harvesting and binning decisions.

With uncompromising quality and build standards the instrument provides you with highly accurate data which you can rely on.

Features and benefits

Designed for farm conditions– this rugged meter is ideal for testing grain for moisture, protein and oil. An automated shutter protects the tester from light, insects and vermin to ensure reliable, low maintenance operation for years to come.

Portable – Compact, light enough to hand carry and powered by 12V to 24V, or battery (up to 2 hours), the Inframatic 8800 goes with you where you need it most: in the pickup truck, in the cab of the header and to the silo. The standard carrying bag protects the IM 8800 and is useful for transporting the instrument to inspection sites, fields etc. It’s also useful for long-term, protective storage of the instrument after harvest.

GPS – The Inframatic 8800 is equipped with a GPS so you can create protein maps of your fields. Make fast harvesting and binning decisions to manage your grain quality.

Protein maps allow farmers to extract additional profit by identifying pockets of premium grain. Topography, fertilization, and run-off are known to cause variation in protein content within a field. The Inframatic 8800 helps you get the most value from the grain you are already producing.

Moisture testing in ground wheat using the optional Moisture Module allows grain traders to use correct moisture value when performing Falling Number analysis. This improves accuracy of Falling Number results.

Uses and benefits
Measure in the field

It’s all about portability and fit-for-purpose with the IM 8800. Place it in the cab of your pickup or harvester. It’s small enough to carry around the field for spot testing allowing you to determine optimal harvest time. The 2 hour battery life and GPS allow you to create protein maps of fields.

Variability of protein in wheat within a single row has been shown to be up to 6%. The maps allow you to capture that value. Maximize profitability by better controlling drying, identifying your highest quality grain, and selling it for a premium.

Quality control before delivery

Deliver the right grain to the right buyer. Test your grain as it’s going into storage and as it’s going into the truck. Send the highest quality grain to those willing to pay premiums. Make sure you get the most for your grain.

Rapid Moisture Measurement for Falling Number Analysis

An accurate moisture value of the sample to be analyzed is critical for correct Falling Number results. Equipped with an optional module the Inframatic 8800 NIR grain analyzer can measure the moisture content of samples before Falling Number analysis, helping grain traders, farmers and others to improve analytical accuracy.

The Falling Number® method is standardized and one critical step in the method is to measure the moisture content of the sample, as this determines the exact sample weight to use. When grinding grain about 0.5-2% moisture is lost in the process. The exact moisture loss depends on factor such as the original moisture content of the grain and whether the lab mill is hot because several samples have just been ground in it. If the user estimates the moisture content of the ground grain rather thanmeasure it, Falling Number results could end up being wrong by several 10s of seconds.

With the Falling Number Moisture Module the Inframatic 8800 becomes a rapid instrument for moisture determination in ground grain and flour. It’s easy to use and gives accurate results in less than 1 minute. Not only does it display the moisture content, it also calculates and displays the exact sample weight you should use in the Falling Number analysis. This means you don’t need to look the weight up in tables, which speeds up the process for you and removes one potential source of error.

Operation and handling

Select the type of grain to analyze.

Pour the sample and press “Start”

After analysis, results are displayed on the screen, and the sample box can be emptied.

On-farm NIR grain analyzer

An on farm grain analyzer has been desirable for some time. The demands on such an instrument are high, however, and must balance many requirements. It must be rugged and robust. It must be portable to tote around the field. It must be simple to operate, but sophisticated enough to provide accuracy similar to elevator and lab instruments. And it must do it all in a cost-effective manner.

Recent technological developments have allowed us to develop just such an instrument. The Inframatic 8800 uses solid state components and diode array technology meaning no moving optical components. The lack of moving parts allows us to align and match instruments at the factory – one instrument is exactly like the next. This means the instruments are accurate, repeatable, and reproducible.

The Inframatic 8800 is standardized to our elevator/lab instrument – the Inframatic 9500. The Inframatic 9500 is well established in the market and is an approved for payment instrument in many countries. It has approvals in the USA, Germany, and Australia to name a few.

Technology

No moving parts

Diode array technology is unique in the sense that it doesn’t use any moving parts in the spectrometer. This greatly improves the stability of the instrument as there are no parts that can be worn out or misaligned. The result is an instrument which requires much less maintenance than when moving parts are used, as for example is the case with scanning monochromators.

  1. A lamp illuminates the sample with white light. Some of the light is absorbed (depending on the composition of the sample) and the rest is reflected.
  2. The light which is reflected hits a stationary grating, which separates the light by wavelength. Instead of white light, we now have a “rainbow”.
  3. Each wavelength is measured by a dedicated detector.
All wavelengths simultaneously

With diode array technology all wavelengths are measured simultaneously, as each wavelength has a dedicated detector. This is necessary in order to be able to analyze a moving sample. Using scanning monochromator technology or Spinning filter wheel, the spectrum is collected one wavelength at the time, and if the sample moves the picture will be blurred.

Line Source Wavelength stabilization

In all optical systems, microscopic mechanical movements occur over time and with temperature changes. These small movements give rise to changes in the wavelength scale and alignment. In order to achieve long term stability, it is imperative to correct for any such changes dynamically. In the DA 7300™ On-line, this is done using a line source which brings the wavelength axis back to the starting point. The benefit with using a line source is that this emits light with peaks at certain wavelengths. The position of these peaks depend on the line source used and is constant with that material. This gives unsurpassed wavelength axis accuracy and long erm stability.

Dual lamp with automatic switch-over.

In order to avoid down-time and costly rush repair jobs, the system is fitted with dual lamps. Once the primary lamp reach the end of its working life, the second lamp is automatically put in to operation in a seamless transition.

Glutomatic® – gluten quantity and quality

$0.00

The world standard for gluten quantity and quality determination

When baking bread and producing noodles or pasta, the flour gluten content and strength will determine the quality of the finished product. The Glutomatic® System is the world standard for determination of gluten quantity and quality.

The effect of gluten quantity and quality in the flour used for bread, cookies, crackers, and pasta is dramatic. In the photo of bread loaves above it is clear that the wet gluten quantity of the flour strongly influences bread volume. Using the Glutomatic® System you will be able to determine the baking quality of wheat and flour.

 

Features and benefits
  • Determine gluten quantity and quality – Improve the quality of your finished products.
  • Official world standard – Ensure that trade contracts are fulfilled.
  • For flour and grain – Determine gluten characteristics both for wheat and flour.
  • Measure true gluten – Only the Glutomatic® can measure true gluten. In a number of situations
    protein content is not indicative of gluten characteristics.

 

Features and benefits

The Glutomatic® System is used worldwide by thousands of grain traders, flour millers, breeders, and pasta/noodle manufacturers, who benefit from its features.

Determine gluten quantity and quality

Improve the quality of your finished products by making sure that your raw materials meet gluten specifications. Higher wet gluten content means higher bread volumes.

Official world standard

For international wheat and flour trade, gluten quantity and quality by the Glutomatic® System are typically specified. Make sure that buyer and seller agree by using the international standard. Approved according to the following standards:

  • AACCI 38-12.02
  • ICC/No. 137/1, 155 & 158
  • ISO 21415-2, 21415-4
  • GAFTA Method 34:2
Easy to use

Confidently operated by non-technical personnel.

For flour and grain

Using Glutomatic® you don’t have to produce a flour to determine the gluten characteristics for wheat. You save time and costs as the Gluten Index method works both for flour and for ground wheat.

Rapid analysis

A complete test takes less than 10 minutes.

Determines true gluten

While gluten is correlated to protein, there are a number of cases where wheat would have a high protein content, but no or very weak gluten. Glutomatic® is the only way to know for sure.

Applications

The quality of dough-based products such as bread, pasta or noodles is highly dependent on the gluten quantity and quality of the flour. This means that everyone in the wheat chain, from breeder to baker, benefit from analyzing and controlling gluten properties with the Glutomatic® System.

Breeding

By measuring the functional properties of protein at an early stage – without having to extract flour – breeders can select the appropriate wheat classes for further breeding and refinement.

Grain Trading and Handling

The ease of use and the speed of the method enable the user to classify the incoming wheat based on gluten quantity and quality, essential for maximizing trade margins and supplying products suitable for varying end-use purposes.

Flour Milling

Millers can blend flour to meet end-user demands while not selling the high-quality product at a low price thereby improving operating margins. With the Gluten Index, the Wet Gluten Content and the Falling Number® analysis results available, millers can quickly predict the final baking quality, reducing the requirement for test baking.

Baking

The gluten properties and structure are important to:

  • Form elastic dough
  • Retain gas during fermentation and baking
  • Allow expansion
  • Carry expansion
  • Retain the shape of the loaf

As baking quality is both related to starch and protein characteristics, a combination of the results from the Falling Number® and Glutomatic® tests can be used to predict the baking quality. With the Gluten quality and quantity information at hand, bakeries are able to use the most cost-effective grade of flour while still meeting end-user quality. Maximizing the use of high-quality flour and minimizing the addition of expensive vital gluten results in substantial savings.

Durum and Pasta

The Gluten Index is reported worldwide in crop reports as an important quality indicator. During pasta manufacturing, gluten has great influence in:

  • Forming non-sticky dough
  • Achieving desired processing characteristics
  • Maintaining firmness and cooking stability
  • Obtaining products with desired cooking characteristics
About gluten

Gluten is the functional component of protein and determines many dough and processing characteristics of wheat and wheat flour.

Gluten consists of the two proteins “Glutenin” and “Gliadin”. It is not until the dough has been made that they actually form gluten. This is why it is not possible to determine gluten in wheat without actually making a dough. Flour, water and the energy from the kneading are all needed for gluten to form. A disulfide bond is then created between the glutenin and the gliadin as illustrated in the picture to the left. Click it to open a larger picture in a new window.

The protein content is a purely quantitative analysis that may or may not be indicative of protein quality. While gluten content and protein content are correlated, there are situations during which protein content will not be indicative of quality. These situations include:

  • Variable Growing Conditions
  • Yearly Growing Variation
  • Wheat Varietal Variation
  • Wheat or Flour Blends
  • Heat Damage
  • Bug Damage
  • Enzymatic Addition

It is under these conditions when the reported protein content is not indicative of the quality that another set of tests is required. The Glutomatic® system is designed to measure protein quality for the following parameters:

  • Wet Gluten Content
  • Dry Gluten Content
  • Water Binding of Gluten
  • Gluten strength by Gluten Index

 

The Gluten Index method
Overview

Wet Gluten is prepared from a whole meal or flour by the Glutomatic® 2200 gluten washer. Gluten Index Centrifuge 2015 is used to force the wet gluten through a specially designed sieve cassette. The relative amount of gluten passing through the sieve indicates gluten characteristics. The wet gluten is further dried in the Glutork 2020 for dry gluten content and water binding in the wet gluten calculation.

The steps in detail

The steps are illustrated in the picture above. Click the picture to enlarge it.

  1. Weighing
    10.0 g ± 0.01 g of wholemeal or flour is weighed and put into the Glutomatic® wash chamber with an 88-micron polyester sieve. When vital wheat gluten is measured, 1.5 ± 0.01 g is weighed.
  2. Dispensing
    4.8 ml of salt solution is added to the meal or flour samples. No salt solution is added to vital wheat gluten samples.
  3. Mixing
    Meal or flour and the salt solution are mixed to form a dough during 20 seconds.
  4. Washing
    After termination of the mixing phase, the washing automatically starts and continues for five minutes. For the wheat meal, the sample is transferred to a chamber equipped with a coarse 840-micron sieve allowing bran particles to be washed out.
  5. Centrifuging
    Exactly 30 seconds after completed washing, the undivided wet gluten piece is transferred to the special sieve cassette and centrifuged one minute at 6000 ± 5 rpm in Centrifuge 2015.
  6. Weighing
    The fraction passed through the sieves is scraped off with a spatula and weighed. The fraction remaining on the inside of the sieve is collected and added to the balance. The total wet gluten weight is obtained.
  7. Drying
    The total wet gluten piece is dried at min. 150°C during four minutes in the Glutork 2020. After drying the gluten is weighed on the balance.
  8. Calculation
    The amount of gluten remaining on the centrifuge sieve in relation to total wet gluten weight is the Gluten Index.
The Glutomatic® System

The Glutomatic® System consists of

  • Glutomatic® 2200
  • Gluten Index Centrifuge 2015
  • Glutork 2020

You also need a lab mill model LM 3100 or LM 120.
