2 food freezing preservation method and frozen refrigerator
The purpose of the invention is to centrally cool warm food such as rice and freeze it, thereby saving the time for rough cooling and improving the quality after freezing and thawing. The invention relates to a freezing method of starchy food such as rice. When the temperature of the food is high, the food is rapidly cooled at a cooling speed of 0.5℃/ min or higher, and when the surface temperature of the food reaches the temperature range of 40-65 0℃, the rapid cooling is stopped to weaken the cooling capacity. Then, when the food temperature reaches the freezing point temperature, the air temperature around the food does not reach -60℃ for rapid cooling.

Sovereignty: 1. A method for freezing food is a method for freezing food containing starch, such as rice, which is characterized in that when the temperature of the food is high, it is rapidly cooled at a cooling rate of 0.5 DEG C/min or higher; when the surface temperature of the food reaches a temperature range of 40-65438+/-0 DEG C, it is stopped to reduce the cooling capacity; and then, for rapid cooling, when the air temperature around the food does not reach-1.
