This rapid viscometer is a rotational viscometer with ramped temperature and variable shear capability optimized for testing the viscous properties of starch, grain, flour and foods. It is a unique tool for research, product development, quality and process control and quality assurance to optimize ingredient use, product formulation and processing conditions. Depending on models, it offers exceptional sensitivity and accuracy when analyzing low viscosity samples and wide dynamic range when analyzing high viscosity samples. With the extended temperature range (up to 140°C), it 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.
