From grain to pellets

To produce safe animal feeds of balanced quality, high-quality raw materials and appropriate plant and equipment are needed. But that alone is not enough. Buhler additionally offers the indispensable expertise required to design the necessary processes. This makes us the technology and market leaders in our field.

The designs of feed production plants and their individual process operations are complex, requiring the appropriate engineering know-how. The following process operations are needed to transform grain into balanced animal feeds: 

Cleaning	Before grinding and pelleting, the impurities contained in the raw materials such as pebbles, earth lumps, metal parts, etc. must be carefully removed.
Proportioning / weighing	Volumetric and gravimetric proportioning equipment feeds the materials to the batch scale to ensure high-precision blending of the specified feed formula ingredients.
Conveying	Equipment for horizontal and vertical conveying of medium- to fine-grained and mealy bulk materials.
Grinding	The material is prepared by hammer mills and roller mills for further processing.
Mixing	The materials weighed and ground exactly according to the feed formulation are mixed homogeneously.
Hygienizing / compacting	The mixed material is hygienized by the addition of steam and thereby conditioned for the compacting process. The compacting process transforms the feed into feed pellets.
Thermal meal treatment	Feeds that are to be fed to animals in the form of meals are subjected to a thermal treatment.
Bagging / palleting	The finished products are prepared for shipment to consumers.
Aspiration	Airjet dust collection filters, small dust collection filters, cyclones, and fans for ventilation and dedusting of feed production plants.
Quality assurance	Samplers, sieving machines, magnetic separators, and other equipment for assuring high formulated feed quality.
Control & automation	Process visualization and control systems for feed production plants.
