Batch mixers for raw material preparation in extrusion processes
Optimize your extrusion process with precise raw material blending, crucial for achieving consistent product quality across varied snack formulations.

Processes and Mixes Raw Material Batches
The Batch Mixer 450 from Schaaf Technologie is engineered to optimize raw material preparation for snack and cereal production lines. Constructed from stainless steel for hygiene and corrosion resistance, this mixer handles two 200 kg batches hourly, feeding the Extruder 640. It employs an optimized design for uniform component mixing and an optional automatic water addition system, ensuring precise moisture levels necessary for product quality. Designed to integrate seamlessly with continuous or batch operations, the mixer enhances process efficiency while allowing easy incorporation into existing systems. Ideal for creating potato chips, cornflakes, and more, it supports automated and manual operations, meeting food industry standards for cleanliness and efficiency.
