Rapid Visco Analyser (RVA)
Available from Perten Instruments, Inc.
The Rapid Visco Analyser is a unique tool for product development, quality and process control and quality assurance.
The RVA is a cooking, stirring viscometer with ramped temperature and variable shear capability optimized for testing the viscous properties of starch, grain, flour and foods. The instrument will analyze as little as two or three grams of sample using international standard methods or your own tailor-made test routines of mixing, measuring, heating and cooling.
Applications include: flour and grain quality, native starches, modified starches and starchy samples, formulated foods (e.g. sauce, ketchup, gravy, dressing, mayonnaise, soup, dairy beverages) other ingredients and foods (e.g. hydrocolloids & proteins), cooked and extruded foods (e.g. ready to eat breakfast cereals, snack foods, pet foods, fish feeds and animal feeds), meltability tests (e.g. process cheese, chocolate and confectionery) and “Miniature Pilot Plant” small scale process emulation.
