Abstract

The invention discloses a multifunctional freezing, fresh-keeping and unfreezing storehouse used for solving the problems that nutrients of food are seriously lost in the freezing and unfreezing processes and the quality of the food is low. The multifunctional freezing, fresh-keeping and unfreezing storehouse comprises a warehouse body and a freezing and unfreezing device installed in the warehouse body. A shelf where food is placed is arranged inside the warehouse body. The freezing and unfreezing device comprises a refrigerating device, a steam heating device and an electric field device, wherein the refrigerating device is used for generating cold air to reduce the temperature in the storehouse body, the steam heating device is used for increasing the temperature and humidity in the storehouse body, and the electric field device is used for generating an electric field so that the food on the shelf can be in an electric field environment. In the freezing process, the refrigerating device and the electric field device are started so that the food on the shelf can be in a low temperature and electric field environment to be cooled and frozen; in the unfreezing process, the steam heating device and the electric field device are started so that the food on the shelf can be in a high temperature and electric field environment to be heated, moisturized and unfrozen, wherein the electric field intensity set in the freezing process is higher than that set in the unfreezing process.

Description

technical field [0001] The invention belongs to the field of food freezing and thawing, and particularly relates to a multifunctional freezing and thawing storage. Background technique [0002] Food freezing refers to reducing the temperature of the food to a predetermined temperature below the freezing point of the food, so that most of the water in the food is frozen into ice crystals, so as to reduce the liquid moisture necessary for microbial activity and food changes, thereby prolonging the food's shelf life. Shelf life. Since the freezing process is strictly affected by temperature, the temperature change and control during the freezing process of food is very important. For example, the water in animal and plant tissues exists in the intercellular space between cells, either in a bound state or in a free state. During the freezing process, when the temperature is lowered to the freezing point of the food, some of the water that is weakly bound to the hydrophilic col...
