Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of seafood thawing, and particularly relates to a rapid thawing device for seafood. Background Art
[0002] Some seafood needs to be frozen quickly after being caught, so as to extend the shelf life of seafood, and at the same time, it is also convenient for subsequent storage and transportation. Only thawing is required for subsequent cooking.
[0003] Rapid thawing can reduce the contact time between seafood and air and moisture during the thawing process, reduce the degree of oxidation and nutrient loss, and better maintain its original taste, flavor and nutritional value.
[0004] Currently, common thawing methods include constant temperature water bath thawing machines, microwaves, etc. Although the thawing effect can be achieved, the water bath thawing machine needs to place the seafood in a water tank. However, during the thawing process, the congestion or impurities in the seafood are likely to pollute the water quality, affecting the quality of the thawed seafood. Secondly, when the seafood is directly thawed in a microwave oven, it is easy to cause uneven heating, resulting in the rupture of some meat cells due to local overheating, damaging the meat fibers, and thus making the texture of the meat rough, loose and lacking elasticity. At the same time, this method may cause the surface temperature of the meat to rise prematurely, resulting in slight cooking, affecting the tenderness of the meat. Summary of the Invention
[0005] The purpose of the present invention is to provide a rapid thawing device for seafood, which can utilize water as a medium to make the seafood heat more evenly during microwave thawing, and maximize the retention of the fiber structure and moisture of the meat.

DETAILED DESCRIPTION OF THE INVENTION
[0019] In order to make the objectives and advantages of the present invention more clear and understandable, the present invention will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present invention, and does not strictly limit the specific protection scope claimed by the present invention.
[0020] As Figures 1 - 10 shown, a rapid thawing device for seafood products includes two mounting plates 1 and several thawing pools 6. Two driving rollers 2 are rotatably connected between the two mounting plates 1. A conveyor belt 3 is drivingly connected between the two driving rollers 2. A bracket 4 is fixedly connected to the bottom surface of the mounting plate 1. A microwave box 5 is installed above the conveyor belt 3 between the two mounting plates 1. It is characterized in that: the thawing pool 6 is located on the conveyor belt 3, and two dispersing components are arranged in the thawing pool 6; A cross beam 10 is fixedly connected between the two mounting plates 1. Two motors 11 are fixedly installed on the top surface of the cross beam 10. A transmission pipe 12 is fixedly connected to the output shaft of each motor 11. A lifting pipe 13 is drivingly connected to the side wall of the transmission pipe 12. The transmission pipe 12 is communicated with the lifting pipe 13. A docking component is arranged at the top end of the lifting pipe 13; A lifting driving component is arranged on the side wall of the lifting pipe 13, and an air inlet component is also arranged on the side wall of the transmission pipe 12.
[0021] As Figure 7 and Figure 8 shown, the dispersing component includes a hollow shaft 7 rotatably connected to the top surface of the inner cavity of the thawing pool 6. A plurality of stirring blades 8 are fixedly connected to the side wall of the hollow shaft 7. The stirring blades 8 are of a hollow structure and are communicated with the hollow shaft 7. The stirring blades 8 are all of an inclined structure.
[0022] Among them, the hollow shaft 7 and the stirring blades 8 can be made of high-temperature resistant ceramic materials, and the thawing pool 6 can be made of glass or ceramic materials to avoid reactions between microwave high temperature and the materials, resulting in problems such as poor thawing or other safety accidents; in addition, the inclination angle of the stirring blades 8 facilitates shoveling and turning the thawed seafood products.
[0023] As Figure 9 shown, the docking component includes a first hexagonal block 14 fixedly connected to the top end of the lifting pipe 13. The first hexagonal block 14 is of a hollow structure and is communicated with the lifting pipe 13. A plurality of internal hexagonal cylinders 15 are rotatably connected to the surface of the conveyor belt 3. The internal hexagonal cylinders 15 penetrate through the conveyor belt 3. The first hexagonal block 14 is adapted to the bottom of the internal hexagonal cylinder 15. A second hexagonal block 9 is fixedly connected to the bottom end of the hollow shaft 7. The second hexagonal block 9 is adapted to the top of the internal hexagonal cylinder 15; When the first hexagonal block 14 and the second hexagonal block 9 are docked with the internal hexagonal cylinder 15, the hollow shaft 7 is communicated with the lifting pipe 13.
[0024] Specifically, when placing the thawing pool 6 on the conveyor belt 3, the second hexagonal block 9 is inserted into the top of the internal hexagonal cylinder 15. After the seafood is thawed, the electric push rod 18 can be activated to drive the lifting pipe 13 upward, so that the first hexagonal block 14 is inserted into the bottom of the internal hexagonal cylinder 15, facilitating the transmission of the motor 11, thereby driving the hollow shaft 7 and the stirring blade 8 to rotate for dispersing the thawed seafood.
[0025] As Figure 9 shown, two clamping blocks 27 are fixedly connected to the side wall of the transmission pipe 12 near the top, and two clamping grooves 28 are formed in the inner wall of the lifting pipe 13. The clamping blocks 27 are slidably connected with the clamping grooves 28.
[0026] Here, when the motor 11 drives the transmission pipe 12 to rotate, the transmission pipe 12 can drive the lifting pipe 13 to rotate through the cooperation of the clamping blocks 27 and the clamping grooves 28. Since the lifting pipe 13 can only perform vertical lifting movement through the clamping blocks 27, when the transmission pipe 12 rotates, the lifting pipe 13 will rotate synchronously, and then the stirring blade 8 can be driven to rotate through the docking assembly to achieve the purpose of turning the seafood.
[0027] As Figure 5 and Figure 10 shown, the lifting drive assembly includes a support 17 fixedly connected to the top surface of the cross beam 10. An electric push rod 18 is fixedly connected to the top surface of the support 17. A docking plate 19 is fixedly connected to the side wall of the lifting pipe 13. The telescopic end of the electric push rod 18 is fixedly connected to the docking plate 19.
[0028] Since the driving method using the electric push rod 18 belongs to the existing mature technology and is widely used, it is used as the driving force of the lifting pipe 13 in this solution. Therefore, it will not be described in detail herein.
[0029] As Figure 6 and Figure 10 shown, the air intake assembly includes a sleeve 20 rotatably connected to the side wall of the transmission pipe 12 near the bottom surface. The cavity between the transmission pipe 12 and the sleeve 20 is the air intake cavity. A plurality of through holes 21 are formed in the side wall of the transmission pipe 12 at the air intake cavity. A connector 22 is fixedly connected to the side wall of the sleeve 20. The connector 22 is communicated with the air intake cavity. A one-way valve 23 is installed on the inner wall of the hollow shaft 7. A plurality of air outlet holes 24 are formed in the side wall of the stirring blade 8.
[0030] Specifically, during the process of dispersing the seafood after thawing, an external air source can be connected through the connector 22 and gas can be injected. The gas enters the transmission pipe 12 from the air intake cavity, then passes through the lifting pipe 13, the internal hexagonal cylinder 15 and the hollow shaft 7 in sequence, and is blown out from the air outlet holes 24, which can increase the fluidity of the water quality. While dispersing the seafood, the fluidity of the water quality is used to promote the thawing of local ice cubes or frozen areas of the seafood, and at the same time, it is convenient to wash away the impurities and congestion attached to the seafood to achieve the purpose of efficient thawing.
[0031] As Figure 10 shown, two annular sealing plates 29 are fixedly connected to the inner wall of the sleeve 20, two annular sealing grooves 30 are formed in the side wall of the transmission pipe 12, the annular sealing plates 29 are rotatably connected to the annular sealing grooves 30, and the air inlet cavity is the area between the two annular sealing plates 29 on both sides.
[0032] Among them, the annular sealing plate 29 and the annular sealing groove 30 are used to seal the sleeve 20. On the one hand, during the air inlet process, the air flow directly enters the transmission pipe 12 from the air inlet cavity, and there will be no air leakage phenomenon. On the other hand, when the transmission pipe 12 rotates, due to the rotational connection relationship between the transmission pipe 12 and the sleeve 20, the sleeve 20 will not be driven to rotate, achieving the effect that rotation and air inlet do not affect each other.
[0033] As Figure 9 shown, a sealing ring 16 is fixedly connected to the end face of the first hexagonal block 14. When the first hexagonal block 14 is docked with the inner hexagonal cylinder 15, the sealing ring 16 abuts against the inner hexagonal cylinder 15 to play a sealing role and avoid leakage during the air flow transportation.
[0034] As Figure 2 and Figure 4 shown, inserting rods 25 are fixedly connected to the bottom surface of the thawing pool 6 near the four corners, and a plurality of inserting cylinders 26 corresponding to the inserting rods 25 are fixedly connected to the surface of the conveyor belt 3. Among them, when thawing seafood, first place the thawing pool 6 on the conveyor belt 3, and at the same time insert the inserting rods 25 into the inserting cylinders 26, which can not only play a role in fixing and positioning, but also support the thawing pool 6.
[0035] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention are implemented according to the conventional means in the art without special description and limitation.
