Description

Technical Field

[0001] The utility model relates to the field of frozen shrimp thawing, in particular to a rapid thawing device for Antarctic krill. Background Art

[0002] Antarctic krill caught in the open ocean needs to be frozen and then transported to the processing plant. Before extracting shrimp oil from the Antarctic krill, the frozen Antarctic krill needs to be thawed. The existing thawing method has a structure that uses microwave heating for thawing, which can achieve efficient and rapid thawing of frozen Antarctic krill. However, in actual use, it is found that when the frozen shrimp on the conveyor belt are thawed, the frozen shrimp close to the conveyor belt receive less microwaves. Under the same thawing time, the thawing effect of the frozen shrimp at the bottom is not good, which affects the uniformity of thawing. Moreover, after thawing, it is easy for a certain amount of moisture to remain on the conveyor belt. The presence of this moisture will absorb a certain amount of microwaves when the frozen shrimp is subsequently thawed, thereby resulting in a decrease in the number of frozen shrimps receiving microwaves, resulting in a decrease in the efficiency of microwave thawing of the frozen shrimp. It takes a longer time for microwave heating to achieve effective thawing, which increases the energy consumption of the Antarctic krill thawing operation. Utility Model Content

With this structure, when the conveyor belt 1 drives the frozen Antarctic krill to enter the microwave thawing box 2, the Antarctic krill placed at a higher height are blocked by the spreading plate 3, and then the raised part is flattened to the rear side as the conveyor belt 1 moves, so that the distribution thickness of the Antarctic krill on the conveyor belt 1 is more uniform, reducing the situation of incomplete thawing at the bottom, and the bottom of the spreading plate 3 is welded or integrally formed with a plurality of fixed parts connected to the top of the conveyor belt 1 The rake teeth 4 contact each other at the bottom. The existence of the rake teeth 4 can rake and plow the frozen Antarctic krill when the conveyor belt 1 moves, so that there is a certain gap between adjacent Antarctic krill, so that the microwaves can reach the bottom position more quickly, thereby improving the contact effect between the microwaves and the frozen shrimps at the bottom, greatly improving the overall thawing efficiency of the Antarctic krill, and improving the uniformity of thawing. A plurality of drying rollers 5 are rotatably connected to the bottom of the conveyor belt 1 through bearings. The drying rollers 5 are heated by any existing heating structure. The drying rollers 5 are in rolling contact with the bottom of the conveyor belt 1. Such a structure makes the conveyor belt 1 that rotates to the bottom and returns after thawing to contact with the plurality of drying rollers 5, so that the residual water on the conveyor belt 1 is quickly evaporated, thereby realizing the rapid drying of the conveyor belt 1, and then when the subsequent frozen shrimps are placed on the conveyor belt 1, the absorption interference of the residual water on the microwave is reduced, the loss of microwave is reduced, the thawing efficiency of the Antarctic krill is improved, and the energy consumption of the thawing operation is greatly reduced.

[0022] Preferably, a frame 6 is provided below the conveyor belt 1, and the frame 6 is used to support the driving structure of the conveyor belt 1. The drying roller 5 is rotatably connected to the frame 6 through a bearing. The frame 6 is provided with a heating component used in conjunction with the drying roller 5. The drying roller 5 is heated by the heating component on the frame 6, so that the drying roller 5 always maintains a certain temperature, thereby enabling the moving conveyor belt 1 to quickly evaporate residual moisture when it contacts it, thereby improving the effect of continuous drying of the conveyor belt 1.

[0023] Preferably, refer to Figure 3 The heating assembly includes a heating tube 7 arranged on the frame 6. The heating tube 7 is generally made of electric heating material and is fixed to the frame 6 by welding or bolts. A drying chamber 8 is provided inside the drying roller 5, so that the drying roller 5 is a hollow structure. The drying chamber 8 is rotatably sleeved on the outside of the heating tube 7. With such a structure, during the process of the conveyor belt 1 and the drying roller 5 rotating and contacting, the heating tube 7 can always maintain the heating operation on the rotating drying roller 5, thereby ensuring that the temperature of the drying roller 5 is maintained within a stable range, avoiding the movement interference of the heating tube 7 and the rotating drying roller 5, and ensuring the effect of maintaining the temperature of the drying roller 5.

[0024] Preferably, the frame 6 is further provided with an air jet pipe 9, and external air or hot air enters the air jet pipe 9. The top of the air jet pipe 9 is provided with a plurality of air jet nozzles 10 used in conjunction with the bottom of the conveyor belt 1. The air or hot air in the air jet pipe 9 is evenly sprayed to the bottom of the conveyor belt 1 through the plurality of air jet nozzles 10, thereby further improving the efficiency of evaporation of water on the conveyor belt 1, further reducing the residual amount of water, and improving the drying effect of the conveyor belt 1.

[0025] Preferably, a water tank 11 is provided at the bottom of the conveyor belt 1. The water tank 11 is a structure with an open top. A plurality of inclined scrapers 12 are welded or bolted inside the water tank 11. The scrapers 12 are in contact with the bottom of the conveyor belt 1. In this structure, before the conveyor belt 1 rotates to the bottom, the plurality of scrapers 12 are used to scrape off the remaining moisture from the conveyor belt 1. The excess moisture falls into the water tank 11 from the opening at the top, thereby ensuring the cleanliness of the thawing environment, reducing the drying pressure of the subsequent drying roller 5 on the conveyor belt 1, and improving the overall drying effect.

[0026] Preferably, refer to Figure 4The spreading plate 3 is tilted, and such a structure makes it easier for thicker frozen Antarctic krill to be spread on the rear side of the conveyor belt 1 after being blocked by the spreading plate 3, thereby avoiding the accumulation of Antarctic krill and improving the spreading effect. Parallel guide rods 13 and screws 14 are arranged in the microwave thawing box 2. The guide rods 13 are welded or bolted to the side walls of the microwave thawing box, and the screws 14 are driven to rotate by a motor. The screws 14 penetrate the spreading plate 3 and are threadedly connected thereto. The guide rods 13 penetrate the spreading plate 3 and are slidably connected thereto. Such a structure utilizes the rotation of the screws 14 to drive the spreading plate 3 threadedly connected thereto to slide back and forth laterally along the guide rods 13, thereby realizing a continuous reciprocating spreading operation of the frozen Antarctic krill and improving the efficiency and convenience of spreading.

Such a structure contacts the plurality of drying rollers 5 when the conveyor belt 1 rotates to the bottom and returns after thawing the frozen shrimps, so that the residual water stains on the conveyor belt 1 are quickly and automatically dried, so that when the subsequent frozen shrimps are placed on the conveyor belt 1 for thawing, the absorption interference of residual water on microwaves is reduced, the efficiency of microwave thawing is improved, the energy loss of microwaves is reduced, and the energy consumption of microwave thawing is greatly reduced.
