As one of the food preservation, quick freezing technology is to put the pre-treated food in a low-temperature facility, pass the largest ice crystal formation zone within 30 minutes, the center temperature drops below -5 degrees, and the ice crystal diameter formed is less than 100 micrometers, and the food center temperature after quick freezing must reach below -18 degrees. Generally, the frozen food is quickly packaged and delivered to consumers at a continuous low temperature below -18 degrees. This is also named as individual quick freezing process.
