Cryogenic Cooling Trays for Food

It’s all about Cryogenius.

Cryogenic cooling boxes

In both the food industry and the automotive industry, cooling trays are widely used for the best cooling of foodstuffs and car parts. These trays, often filled with liquid nitrogen, make it possible to temporarily immerse objects in them, thereby cooling them at lightning speed.

Mainly in the food industry, refrigeration is central. Manufacturers invest in the best freezing equipment to freeze their food efficiently and keep it cool for as long as possible. This is because good refrigeration is essential for product quality and storability.



For the food industry, Demaco mainly supplies long, rectangular, open, cryogenic cooling trays. These trays are typically insulated with PIR insulation boards and use our level controllers. This preserves the extremely low temperature of the cryogenic liquid used, and also maintains optimum cooling performance.

As the food industry deals with strict hygiene rules (the HACCP requirements), we have chosen to produce cryogenic cooling trays that are easy to clean. In addition, our trays feature a convenient gas pipe that considerably speeds up emptying the cooling tray. 

Applications of cooling trays for food

Refrigerated food containers are used to freeze and keep various products cool. Think, for instance, of vegetables, fruit and ice cream. With this method, freezing is fast and in the right way. This helps producers maintain quality, also when products have to be kept for a longer period of time.

In the food industry, cooling trays are especially used for dipping, for example during the production of ice cream. By briefly cooling the ice cream in a bath of nitrogen, a thin layer of, for example, chocolate or fruit are formed over the surface of the ice cream . Thanks to this rapid process, the rest of the ice cream retains its required temperature and quality. In the food industry, cooling trays are also called dipping trays for this reason.

Accessory products

Cooling trays are always part of a cryogenic infrastructure featuring vacuum insulated piping and quality enhancing products such as a phase separator and possibly other additional products. We supply all the products needed for the optimal performance of a cooling tray system.
