Extrusion is the central process in the production of many foodstuff s and feedstuff s. Extruders knead, mix, cook and portion cereals, cornflakes and pasta, textured proteins, vitaminized rice and pet foods, for instance. Along with sophisticated technology and a lot of processing know-how, temperature control represents a decisive factor.
Requirements
To ensure that the products have a uniform quality, consistency and taste, the processing temperatures have to be carefully and reproducibly controlled. For instance, any cooking process needs to be timed very exactly. Generally, several different product recipes are involved, so the process temperature regulation also has to be flexible and it must be possible to automate it reliably. Finally, high levels of operating and product safety as well as energy efficiency across the whole process are important goals as well. The robust valve technology in the Modular Process Control Platform can fulfil these requirements in all respects.
