The RVA-20 is a specialized instrument used to test the viscosity and its changes of samples. A reasonable design enables it to quickly heat or cool the sample or maintain a constant temperature, making it easy for users to choose testing conditions based on the purpose of the test. The RVA is currently the most effective analytical tool used to analyze and test the gelatinization characteristics of grains, grain processed products, and starch. More and more scientists around the world are using it to study the process quality characteristics of grain raw materials and the impact of various additives and processing techniques on the quality of grain products or other processed products.

1. Data analysis: The software page is adjustable in both Chinese and English, making it easy to operate and easy to get started. During data analysis, there is no need to write a separate analysis program. Users can directly select the desired parameters, and the software can automatically calculate the results. The result data and curves can be exported to Excel documents and images;
2. Self-contained method library: Self-contained testing method library, which includes specific sample names for testing, preparation methods for sample testing, testing parameter settings, experimental curve diagrams, and how to analyze results after testing;
3. The software comes with a knowledge base of food properties, rheology, thermodynamics, electricity, and other related knowledge, which can be retrieved and analyzed at any time within the software; Equipped with national standard algorithms, software can be directly called;
4. The software comes with an experimental report, which includes experimental information, experimental parameters, experimental graphs, and experimental results. The experimental report can be exported with one click, and cannot be edited. It can achieve experimental traceability function
