RVA-TecMaster, 240V, 50/60Hz

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.

Overview

A fully featured viscometer for analyzing most samples. It covers the mid viscosity range (20 - 8,000 cP at 160 rpm). General purpose applications include the following:

  • Starches and starchy samples
  • Hydrocolloids
  • Proteins
  • formulated, cooked and extruded foods
  • "Miniature Pilot Plant" small scale process emulation

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)
  • "Miniature Pilot Plant" small scale process emulation.

The new RVA 4800 can perform regular tests below 100°C, as well as high-temperature tests up to 140°C in a specially designed pressure vessel. With the extended temperature range (up to 140°C), the RVA 4800 provides a tool for performing more relevant analysis for a variety of applications, including ingredient (e.g. starch and hydrocolloid) performance under conditions relevant to ultra-high-temperature (UHT) pasteurization of dairy and food products, retorting, pressure cooking, extrusion and other aseptic processing conditions.
