levyjäädytin

A levyjäädytin, or plate freezer, is a type of industrial freezing equipment used for rapidly chilling or freezing food products. It consists of a series of flat, hollow plates through which a refrigerant circulates. When food is placed between these plates, the refrigerant draws heat away from the product, facilitating efficient freezing.

Levyjäädyttimet are designed for high-capacity freezing and are particularly well-suited for products that can be formed into flat, relatively thin layers. This includes items like fish fillets, meat patties, vegetables, and fruit. The direct contact between the food and the cold plates ensures excellent heat transfer, leading to faster freezing times compared to other methods. This rapid freezing is crucial for preserving the quality, texture, and nutritional value of food products.

The plates in a levyjäädytin are typically made of stainless steel for hygiene and durability. They are often hydraulically pressed together to ensure uniform contact with the food. The equipment can be configured in various ways, including vertical and horizontal units, to accommodate different product types and production line layouts. The refrigerant used can vary, but common options include ammonia or Freon. Maintenance usually involves cleaning the plates and checking the refrigeration system.
