METHOD AND DEVICE FOR REDUCING THE AMOUNT OF ANTI-NUTRITIONAL FACTORS IN RAW MATERIAL MIXTURE FOR FEED.

摘要

The invention relates to a method for reducing the amount of anti-nutritional factors in a raw material mixture for producing an ingredient for animal feed such as cattle fodder or domestic animal feed, which raw material mixture contains at least rape seed in a quantity between 1 and 100%, by subjecting the raw material mixture to a steam treatment for a predetermined time at a predetermined temperature. Due to the steam treatment the anti-nutritional factors are at least partially broken down and determined constituents such as fats also become better accessible, whereby the nutritional value of the final animal feed increases. The invention also provides a device for performing the method, which device comprises at least a steam treatment unit.
