Description
Technical Field
The invention relates to the technical field of refrigeration equipment, in particular to liquid quick-freezing equipment.
Background
Conventional freezing devices use air as a heat transfer carrier, which is limited by the low thermal conductivity of air and the long freezing time of the food product. During freezing, the extracellular solution first produces ice crystals, and the water inside the cell flows to the ice crystals outside the cell under the action of vapor pressure, so that larger ice crystals are formed and distributed unevenly. Due to protein denaturation, the cell membrane loses water more easily, thereby further increasing the volume of ice crystals. Large ice crystals break the cell wall, causing cytoplasmic efflux, which in turn causes a reduction in food quality. Meanwhile, when the food is frozen, the freezing speed is gradually reduced from the surface to the center, and the quality of the food is easily reduced due to uneven distribution of the freezing speed. After long-time freezing, the large ice crystals can destroy the tissue structure, cells can not restore to the original state after unfreezing, cell sap is greatly lost, the flavor and the quality of food are influenced, and even the food can not be eaten.

Compared with the existing freezing technology, the method mainly brings the following beneficial effects.
Firstly, the thermal conductivity of the liquid is dozens of times of that of air, and the liquid is used as a heat transfer medium, so that the freezing speed of the food material is obviously improved, and the freezing time is shortened.
Secondly, the cavitation effect generated by the ultrasonic wave in the freezing process protects the tissue structure and the cell structure of the frozen food, namely protects the quality of the frozen food. This is mainly reflected in the following aspects:
firstly, the heat transfer efficiency of the frozen object is improved by ultrasonic waves, so that the frozen food forms a plurality of fine ice crystals in and out of cells, and the damage effect of the ice crystals on cell membranes is reduced; second, cavitation acts simultaneously on the intracellular and extracellular matrices to induce nucleation (the intracellular matrix is not nucleated if there is not sufficient supercooling in conventional freezing processes). Because the formation of crystal nucleus in the cell matrix inside and outside, the water migration caused by osmotic pressure is established, thus reducing the deformation and structural damage of the cell. Thirdly, the shock wave and the micro jet generated when the cavitation bubble of the ultrasonic wave is broken destroy the mechanism of the ice crystal sharp, thereby reducing the damage of the ice crystal to the cell membrane.
In sum, the invention obviously improves the freezing speed of the frozen food and better protects the original quality of the food.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
