Powdery food product e.g. dried milk, decontaminating method, involves producing vertical flow of powdery food product by gravity from powder feeding system, and subjecting product to ultra-violet flash during flow of product

摘要

The method involves producing a vertical flow (4) of a powdery food product (P) e.g. dried milk, by gravity from a powder feeding system (8) provided with a hopper (9), where the flow reaches a product recovery system (11). The flow of the product is carried out within a gaseous medium e.g. oxygen medium, without contact of the product on a wall. The product is subjected to a ultra-violet flash emitted by a flash lamp (2) of a light source, during the flow of the product. An independent claim is also included for a device for decontaminating a powdery food product.
