Abstract: The present invention concerns a procedure and system for producing a cryogenic product, more precisely supercooled ice, and application of this product. In accordance with the present invention, the cryogenic product is produced based on ice in various forms/pieces. The ice, which is made from fresh water and/or salt water, possibly with other additives, is mixed with a cryogenic agent such as carbon dioxide in solid form or liquid form and/or liquid nitrogen and/or liquid air to form a mixture. The carbon dioxide is subsequently permitted to sublimate almost completely and/or the nitrogen and/or the liquid air is permitted to boil before the product is finished and the carbon dioxide gas and/or nitrogen gas is removed from the product. The system comprises a mixer (2 or 102) with an inlet (3 or 107) for the supply of a cryogenic agent and a supply pipe (5 or 103) for the supply of ice, and the mixer comprises means (2 or 102) for mixing the products stated and an outlet (6 or 105) for the removal of the finished product. An extraction system (4 or 104) is provided to remove carbon dioxide gas and/or nitrogen gas. The temperature in the cryogenic product can be maintained, the temperature increase can be reduced, or the temperature in the product can be further lowered by storage in a freezing room. The cryogenic product is particularly well suited for the processing/treatment/transport/storage of products, for example foods, especially fish and other seafood products.

Abstract translation: 本发明涉及用于生产低温产品，更确切地说是过冷冰的方法和系统，以及该产品的应用。 根据本发明，低温产品基于冰以各种形式/件生产。 由淡水和/或盐水制成的冰，可能与其他添加剂一起，与固体形式或液体形式的二氧化碳和/或液氮和/或液体空气的低温剂混合，形成混合物 。 随后允许二氧化碳几乎完全升华和/或氮气和/或液体空气在产品完成之前被允许沸腾，并且从产品中除去二氧化碳气体和/或氮气。 该系统包括具有用于供应低温剂的入口（3或107）和用于供应冰的供应管（5或103）的混合器（2或102），并且混合器包括装置（2或102） 用于混合所述产品和用于去除成品的出口（6或105）。 提供提取系统（4或104）以去除二氧化碳气体和/或氮气。 可以保持低温产物中的温度，可以降低温度升高，或通过储存在冷冻室中可以进一步降低产品中的温度。 低温产品特别适用于加工/处理/运输/储存产品，例如食品，特别是鱼类和其他海产品。
