The blast freezer is not used to store meat, but is used to quickly freeze meat at normal or low temperatures to below -18 °C. With a blast freezer, food can quickly pass through its largest ice crystal formation area, avoiding the formation of large amounts of ice crystals and preventing the destruction of the structure of food cells. Therefore, frozen food meat is more authentic than untreated meat. Generally, the temperature for freezing storage is usually -15° C to -35° C.
