At present, common thawing modes generally comprise natural thawing, soaking thawing, microwave thawing and the like, wherein the natural thawing and the soaking thawing have the defects of large occupied area and long thawing time, and although the microwave thawing is quick, the thawing is not uniform, so that the processing quality and the taste are influenced.
Disclosure of Invention
The utility model aims at providing a frozen aquatic products thawing apparatus that unfreezes fast, unfreeze effectual.
The utility model discloses a frozen aquatic product thawing device, which comprises a cold water pool and a vibration table; the cooling water tank is connected with a cooling water supply device, a plurality of cooling water tanks and a plurality of vibration tables are arranged at intervals, an inclined conveying belt is arranged between every two adjacent cooling water tanks and vibration tables, one end of each conveying belt is immersed in the corresponding cooling water tank, and the other end of each conveying belt extends upwards in an inclined mode to the position above the feeding end of the corresponding vibration table; the table top of the vibrating table is arranged in an inclined mode, the inclined direction of the table top is gradually reduced from the feeding end to the discharging end of the vibrating table, and the table top extends to the position above the conveying belt in the cold water tank at the discharging end of the vibrating table.
The working principle of the unfreezing device for the frozen aquatic products is as follows:
putting the frozen aquatic product above a conveying belt in a first cold water tank, wherein the conveying belt moves slowly, the frozen aquatic product moves from the first cold water tank to a first vibration table, in the process, the surface of the frozen aquatic product is frozen, and the interior of the frozen aquatic product starts to be gradually thawed under the action of heat released by freezing of cold water; when the ice layer on the surface of the frozen aquatic product is thick and affects the heat transfer to the interior of the frozen aquatic product, the frozen aquatic product is conveyed to the first vibrating table by the conveying belt, the ice layer on the surface of the frozen aquatic product is vibrated to be broken and fall off by the vibration of the first vibrating table, and the table top of the vibrating table is inclined, so that the frozen aquatic product without the ice layer on the surface gradually moves towards the second cold water tank and finally falls onto the conveying belt of the second cold water tank in the vibrating process, and the second section of freezing process is started. After the steps of freezing and deicing of the cold water tanks and the vibration table, the frozen aquatic products can be thawed quickly and uniformly inside and outside. Because the plurality of cold water pools and the vibrating table form a defrosting assembly line, the defrosting efficiency can be greatly improved, and the device is very suitable for defrosting of large-batch frozen aquatic products in an aquatic product processing factory.
The principle of the thawing method is as follows:
after the frozen aquatic product is put into cold water, the ice layer on the surface can be generated due to the fact that heat in the water is absorbed, but in the freezing process, the temperature of the ice layer is kept unchanged, the water is continuously heat-releasing in the freezing process (1 g of water is frozen into ice to release 80 calories of heat), and the heat is transmitted to the aquatic product with low temperature from the water with high relative temperature, so that ice crystals in the aquatic product are gradually thawed. After the ice layer on the aquatic product is thick, the capacity of transferring heat to the aquatic product by the ice layer can be rapidly reduced, the ice layer on the surface of the frozen aquatic product is removed, the aquatic product is put into cold water again, and the steps of freezing and deicing are repeated, so that the heat in the water can be rapidly transferred into the aquatic product, the interior and the exterior of the aquatic product are thawed consistently, the thawing speed is increased, and the problem that the cell wall is broken due to rapid rise of the surface temperature of the aquatic product, and further the nutrient substance in the aquatic product is lost is solved.
Furthermore, the plurality of cold water pools are communicated through water pipes, and the cold water supply equipment is respectively connected with the cold water pools at the head and tail positions through the water inlet pipe and the water outlet pipe, so that one cold water supply equipment can be used for supplying cold water to all the cold water pools, and the pipeline connection is simplified.
The utility model discloses utilize cold water to freeze exothermic principle to adopt pipelined's thawing apparatus, can improve the speed of thawing greatly when guaranteeing the effect of thawing, have fine practicality.
