VA4800Rapid viscosity analyzerDetect the viscosity and processing characteristics of starch, raw materials, ingredients, and food by accurately controlling temperature and shear force. Can be used to describe the quality of raw materials, intermediate semi-finished products, and final products to optimize quality and improve performance. With the testing of high temperatures up to 140 ° C, RVA4800 will become a research tool suitable for various application analyses, including the performance of raw materials such as starch and hydrocolloids in certain specific processing processes, such as ultra-high pressure sterilization of dairy products and food, dry distillation treatment, high-pressure cooking, extrusion puffing, and other aseptic processing processes. The temperature and stirring speed (shear force) can be set according to standard methods or customer customized methods. RVA can be used as a small testing device to simulate actual production and processing processes, such as heating, cooling, and mixing. RVA4800 is connected to a computer for operation and data processing through TCW3 software. TCW3 software comes with a testing method library suitable for various applications, with up to 67 methods available.
RVA4800 is a tool that combines fast testing speed, flexible use, high accuracy, and automated testing. It can be widely used in product development, process monitoring, QC and QA optimization of ingredients, product formulations, and process conditions.
