cabinet freezing system ◼ The product is placed in a package prior to freezing, and the packages are p1aced on trays before they are moved into the freezing system. These types of freezing systems operate as batch systems, with ti1e freezing time established by the length of time that the product remains in the cabinet. The environment in the room is maintained at a low temperature, and air movement is established by fans within the cabinet

Plate freezing system ◼ In these types of freezing systems, the product is held firmly between two plates throughout the period of time required for product temperature reduction. The plates are the primary barrier between the cold refrigerant and the product. These types of freezing systems have a definite advantage when the product configuration allows for direct and close contact between the plate surface and the product surface
