Milk powder

Powdered milk is a key product in many countries. It fills the gap where local farms do not supply all the needs of a given market. The powdered product is prone to bacterial contamination that survives the desiccated stage and reactivates when rehydrated. There is a possibility of contamination from undetectable foreign bodies such as white fibers from fraying plied belts. To complicate matters, cleaning is dry without a wash down. A homogeneous Volta belt was used in one plant where pharmaceutical grade chemicals are recovered from the powder. It has experienced bacteria counts of 12ppm after a dry wipe down. A result that astonished the QA department and helps the company maintain its high standard of purity.
