Claims7
A method for freezing food items, said method comprising:
- a) receiving food items,
- b) bringing the food items to an under-cooled state in salt-controlled and temperature-controlled liquid in at least one first container by:
- i) determining the salt concentration of the liquid and maintaining the temperature of the liquid such that the temperature is higher than the freezing point of the liquid, and
- ii) providing substantially continuous movement of the food items in the liquid during the step of bringing the food items to an under-cooled state,
- c) subjecting the food items to a temperature balancing step to allow the food items to rime before freezing the food items,
- d) transferring the food items to a receptacle for freezing, and
- e) bringing the food items to a temperature between −4 and −24° C. for storage before processing, wherein step c) is performed after bringing the food items to an under-cooled state and prior to freezing the food items.
