申请
Milling and Baking
用户可以测试谷物是否有声音和虫子损坏，面糊，面包，蛋糕，面条和面食的淀粉粘贴质量，真菌淀粉酶，面粉淀粉酶，抗缝制，抗缝制，面粉的热处理，麦芽淀粉酶，小麦麸质质量和溶剂保留能力。
Starches and Starchy Samples
Native starches of tubers, roots, grains and others can be subjected to standard and custom starch pasting tests. Users can perform custom high shear and extended temperature tests to track the production and end quality of modified starches for food, feed, pharmaceutical and industrial applications.
挤出和煮熟的食物
可以在预处理器，挤出机和成品阶段测试淀粉转化或“烹饪程度”，即即食零食，早餐谷物，宠物食品，动物饲料和水饲料。
麦芽和酿造
Users can predict safe storage life for malting barley, test fast recording mashing system (and the impact of adding chemicals, enzymes and adjuncts to malts), monitor the advancement of malting and estimate barley malting quality and simulated industrial mashing process.
Dairy
The Rapid Visco Analyser helps test process cheese manufacture and melting profile, the impact of drying temperature on milk protein powders, rennet caseinate rehydration, custard, dairy beverages, ice cream mix and dairy desserts, as well as age thickening of sweetened condensed milk and “Miniature Pilot Plant” small scale manufacture of yogurt.
Formulated Foods
用户可以测试产品（准备使用和预混合物）的粘度概况，例如肉汁，酱汁，蛋黄酱，番茄酱，调味料，汤和其他低粘度食品，该食物配以蛋白质，淀粉和水胶机制成。他们还可以对生产条件进行融化测试，例如巧克力和糖果和“微型飞行员植物”的小规模仿真。
原料
The development of the viscosity of proteins like milk proteins, egg whites, soy products, gelatin and gluten can be tested. Gelling/thickening profile and hydration performance of a system can be tested while cooling to identify the hydrocolloid behavior. Samples can be precisely prepared for other kinds of rheological assessment.
Different RVA Models
RVA 4800
The RVA 4800 is PerkinElmer’s top-of-the-range model that integrates exceptional sensitivity and accuracy, an extensive viscosity range and an extended temperature range (of up to 140 °C). Thus, the RVA 4800 is an ideal tool for carrying out more relevant analyses for a range of applications.
应用包括在与乳制品和食品的超高温度（UHT）巴氏杀菌有关的条件下的成分（例如氢胶样和淀粉）的性能，压力烹饪，反驳，挤出，挤压和其他无菌处理条件。

RVA TecMaster
RVA TecMaster is a completely featured viscometer that helps analyze a majority of the samples. It works in the mid-viscosity range of 20 to 8,000 cP at 160 rpm. The following are the general-purpose applications of this system: formulated, cooked and extruded foods, starches and starchy samples, proteins, hydrocolloids and “Miniature Pilot Plant” small-scale process emulation.
