Description
technical field [0001] The invention relates to food freezing technology, in particular to a rotary spray freezing device. Background technique [0002] Fish, meat, processed food, etc. should be stored for a long time, such as more than one month, they must be frozen. Generally, the lower the temperature of the food, the slower the quality change. In addition, the drying rate caused by evaporation also weakens with the decrease of temperature. The freezing of food usually includes slow freezing, quick freezing, quick freezing and super quick freezing. In the ventilated room, slow freezing is used for freezing large-volume food, and the food in the belt freezing device is quick-frozen or deep-frozen. Quick freezing is used for single-grain small food on the vulcanized bed, and ultra-quick freezing is to use low-temperature liquid spray or immersion freezing. The current ventilated room or belt type freezing device usually occupies a large area, while the main problem of t...
