A cooling bed consists of a drive system that cycles fixed and moving rakes. The rakes then "walk" the product across the cooling bed as it cools at a predetermined rate. The cooling rate is dependant on the required structure of the material. Each type of cooling bed needs an entry and exit solution to prevent damage to the product.
