Perten Instruments has launched a specially-modified stirring paddle that allows low viscosity fluids to be injected into the sample can during a test in the RVA.

This enhances the RVA ''miniature pilot plant'' application in which the RVA is used as a tiny batch cooker to produce ultra small scale food formulations in a very low cost, efficient and rapid new product development process.

The RVA can make 10-20 grammes of products and process multiple batches a day whereas larger-sized pilot processing plants can only produce one or two batches per day and may require thousands of litres per batch. Sample may also conveniently be withdrawn from the RVA can for other tests using the modified paddle.

RVA ''Miniature Pilot Plant'' applications include manufacture of yoghurt and other cultured soft dairy products, ice cream pre-mix, cream cheese, soft dairy desserts, and tofu, assessment of enzyme activity for bioethanol production and assessment of enzyme and ingredient effects in baking and cheese making.

Based in Stockholm, Sweden, Perten Instruments specialises in quality control of grain, flour, feed and food, and offers a wide range of analytical equipment for these equipments. The company is active in 100 countries worldwide and has offices in China, Germany, Australia and the US.
