Description
Technical Field
The utility model belongs to the technical field of the refrigerator, concretely relates to air supply wind channel and refrigerator of refrigerator drawer.
Background
The freezing speed is different according to food and equipment, and generally the higher the freezing speed is, the better the freezing speed is, for example, the fish flesh myosin has the fastest variation between-3 ℃ and-2 ℃, so that the fish flesh myosin can pass through the temperature section as soon as possible when needing to be frozen. At a certain temperature range (-5-1 ℃), most of the water in the meat product is frozen to form a large amount of ice crystals, and the temperature region is called as a maximum ice crystal generation zone. The moisture state inside the food is greatly changed in this temperature range, and the quality of the food is also greatly changed. A large amount of data prove that meat passes through the largest ice crystal zone in the shortest time, the ice crystal is generated quickly, and a plurality of small crystal nuclei are generated quickly, so that a plurality of broken crystals are easily formed, and the quality of food is ensured.
The existing refrigerator drawers basically do not comprise quick-freezing drawers or only comprise freezing drawers which can not enable meat to pass through ice crystal strips quickly. In the slow freezing process of the freezing drawer of the existing refrigerator, extracellular solution firstly generates ice crystals, water in cells flows to the ice crystals outside the cells under the action of steam pressure, and then larger ice crystals are formed and are unevenly distributed. Due to protein denaturation, the cell membrane loses water more easily, thereby further increasing the volume of ice crystals. Large ice crystals can disrupt cell membranes, causing cytoplasm to flow out, and further causing the degradation of food quality. In addition, when the food is frozen, the freezing speed decreases from the surface to the center, and the quality of the food is likely to be deteriorated due to uneven distribution of the freezing speed. When the frozen food is frozen for a long time, large ice crystals can damage the tissue structure, cells can not restore to the original state after being thawed, cell sap is greatly lost, the flavor and the quality of the food are influenced, and even the situation that the food cannot be eaten is caused.
SUMMERY OF THE UTILITY MODEL
