Shanghai Baosheng Rapid Viscometer RVA Product Introduction:

1. What is RVA?

RVA stands for Rapid Visco Analyzer. It is an instrument used to test the viscosity and its changes of a sample. Reasonable design enables it to quickly heat or cool the sample or maintain a constant sample temperature, making it easier for users to choose testing conditions based on the purpose of the test. RVA is currently an effective analytical tool used to analyze and test grains, processed grain products, and starch gelatinization properties. 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.

2Shanghai Baosheng Rapid Viscometer RVAIntroduction

High sensitivity and accuracy are suitable choices for detecting low viscosity samples (10cP at 160rpm for low viscosity). Low viscosity testing includes: low solid content starch (such as ethylated starch and cationic starch in the paper or packaging industry), low viscosity food starch (such as acid hydrolyzed or enzymatically hydrolyzed starch), low viscosity products (such as soy sauce, tomato sauce, meat juice, seasonings, mayonnaise, soups, and dairy beverages), and other low viscosity non starch foods (such as colloids and proteins). It is also suitable for analyzing samples with a wide viscosity range (up to 25000 cP at 160rpm). High viscosity testing includes: extruded and puffed foods (such as breakfast cereals, snacks, pet food, fish feed, and animal feed), fusibility testing (such as artificial cheese, chocolate, and candy), high solid content starch, and high viscosity modified starch (such as substituted and cross-linked food starch).

Application of Shanghai Baosheng Rapid Viscometer RVA inStructural features:

Fast testingThe temperature change rate during heating or cooling can be controlled by software equipped with a computer, up to 14 ℃/minute. Completing a regular standard test only takes 13 minutes. Quick testing only takes 3.5 minutes.

Easy to operate:Due to the fact that the testing process and analysis of test results are all controlled by computers, the operation of RVA is very simple, and the operation of analyzing test results is also very easy.

Strong reliability:Due to the reliable monitoring system and computer-controlled regulation of temperature and stirring speed changes, the test results (including gelatinization curves and test parameters) have a high degree of repeatability and reproducibility.

High accuracy:Except for sample preparation and certain necessary basic operations, the testing process is automated, so human error factors can be minimized to ensure high accuracy of the test results.

Strong flexibility:Users can use RVA's computer software to freely change testing conditions or select testing programs based on the characteristics of the sample, and can also order different models of RVA according to their own business needs. Therefore, RVA has a wide range of applications, strong adaptability, and high flexibility.

Wide adaptability:RVA has a wide range of applications in grain storage and processing, seed science, food science, grain science, crop breeding, and fermentation industries. It is an ideal quality analysis and testing instrument for grain scientists, plant breeders, grain traders, flour or starch production technicians, beer manufacturers, seed distributors, food producers, and feed producers who need to understand the corresponding raw materials or products.

accepted:Not only are more and more scientists from various countries using RVA, but several methods that use RVA as a basic tool for testing have been recognized or are being recognized by recognized organizations such as ICC and AACC as widely applicable standard methods.
