R&D SCALE STEAM COOKER - Replicate RotaTherm settings in 2-3kg batches


Replicate the processing conditions of the RotaTherm® in a small batch style steam cooker for small volume R&D.

» Replicates RotaTherm® in 2-3kg batches.
» Easy adjustment via a touch screen.
» Pasteurise, UHT.

R&D scale steam cooker: MicraTherm


The Natec Network MicraTherm is designed to best replicate the processing conditions of the RotaTherm® continuous cooker in a batch manner, to both pasteurise and UHT levels. Using the same direct steam injectors and rotor principle as the RotaTherm®, it provides the opportunity to perform R&D over a wide range of products, viscosities and processing parameters in cooking cycles of two to three kilograms. PLC controlled with a touch screen and trending recorder the MicraTherm provides an excellent tool for product development for the RotaTherm® continuous cooking system.
