Micro ViscoAmyloGraph®
Combined solution for flour and starch applications
Micro ViscoAmyloGraph®
• Small Sample Weights
• Quick Measurement
The NEW Micro ViscoAmyloGraph® evaluates starch or flour samples at a fraction of the standard requirements without neglecting the need for accuracy and reliability.
Only 5-10 grams of sample are needed for an evaluation. Total test time can be reduced by the elevated temperature rate increase (up to 10 degrees C/minute).
• small sample weights
• heating/cooling rates of up to 10°C/min
• short measuring times • fully electronic measurement
• integrated, self-optimizing temperature control unit
• temperature measurement within the sample • easy handling and cleaning
• variable speed
Benefit from the versatility and reliability of the Micro Visco-Amylo-Graph® - in the food industry, in the paper and textile industries, or in the chemical industry:
• Measure the gelatinization properties of flour and native or modified starch
• Measure the enzyme activity of flour (e.g. sprout)
• Adjust the diastatic activity by adding enzymes (e.g. malt flour)
• Measure the influence of extrusion conditions onto the extruded product
The Principle
The measuring principle is similar to that of the Viscograph-E: a starch-water or flour-water suspension is heated in a rotating bowl and cooled down again, both under controlled conditions. Use the standard procedure (heating - holding - cooling) or save your own temperature profiles.
The measuring sensor, which completely immerges into the sample is connected to a high-resolution torque sensor for precise viscosity determination.
The special geometry of the stirrer ensures good mixing of the sample - there is no sedimentation of starch particles. Temperature measurement directly within the sample makes it easy to consistently and precisely assign the temperature to the current viscosity.
Due to the automatic return-type steam trap, there is no loss due to evaporation. The small measuring bowl allows you to reduce your sample weights to as little as 5...15 g for 110 ml of water, depending on your sample.
Software
The NEW Micro ViscoAmyloGraph®, following previous Brabender® models, monitors and records actual stock temperature. Modern state-of-the-art correlation software allows operator to compare up to 15 different curves.
