Cryogenic Cooling Trays in the Food Industry

It’s all about Cryogenius.

Cryogenic cooling boxes

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


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

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 in the food industry

In the food industry, cooling trays are widely used for dipping, for example during the production of ice cream. By briefly dipping the ice cream in a bath of nitrogen, a thin layer of, for example, chocolate or fruit can be fixed around 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.
