The invention relates to a method of producing frozen products in which a predetermined amount of carbon dioxide snow is produced and piled up to form a volume of snow. Subsequently, a mold impression is pressed into one surface of the snow volume, forming depressions into which at least one product to be cooled is filled. In a cooling device, the product in the snow volume is cooled through, while the snow volume itself gradually sublimates. The process and the device are particularly suitable for the production of individual quick freezing (IQF) products.

Method and apparatus for producing frozen products

In order to meter carbon dioxide snow, a storage container has an output unit, which comprises: an output opening, which is arranged laterally in the bottom region of the storage container; and a horizontally movable sliding element, which cooperates with the output opening. In order to fill the storage container with carbon dioxide snow, at least two snow horns are provided on the storage container, in which snow horns liquid carbon dioxide is converted into a mixture of carbon dioxide snow and carbon dioxide gas. The mouth openings of the snow horns point toward each other at least in one direction component so that the material flows exiting therefrom are directed at least partially toward each other. This facilitates the separation of snow and gas and increase the efficiency of the device.

The present invention relates to the transport of products in a desired conservation temperature range, comprising:

A cooling system using carbon dioxide as a coolant comprises a cooling chamber for storing products to be cooled during transport and a cooling unit for cooling the atmosphere in the cooling chamber. The cooling chamber and the cooling unit are mounted on or integrated in a cooling vehicle like a truck, a railway wagon or a ship. The cooling unit comprises a carbon dioxide storage compartment and at least one cooling channel through which air is led from and to the cooling chamber. The carbon dioxide storage compartment and the cooling channel are separated from each other by a thermal well-conducting but gas-tight plate serving as a heat exchanger between the carbon dioxide in the carbon dioxide storage compartment and the air in the cooling channel.
