Technical Field

[0001] This utility model belongs to the field of aquatic food processing technology, and in particular relates to a thawing device for aquatic food processing. Background Technology

[0002] Aquatic products are a general term for aquatic animal and plant products and their processed products produced by marine and freshwater fisheries. Aquatic foods are rich in nutrients and have different flavors. Fish meal and concentrated fish juice made from low-value fish and processing waste are important protein feeds. Aquatic protein products made from aquatic animals and plants have multiple uses in chemical and pharmaceutical products.

[0003] The current thawing devices typically place thawed seafood in a filter frame, which is then placed in a thawing chamber. A heating fan is attached to the bottom, and a lifting mechanism is used to remove the seafood. However, this process results in the accumulation of seafood during thawing, and the small contact area between the food and the hot air not only affects the thawing effect but also poses certain safety risks.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] like Figures 1-3 The diagram shows a structural representation of a thawing device for processing aquatic foods according to an embodiment of this invention. It includes a base plate 1, with a first fixing rod 2 and a second fixing rod 3 fixedly mounted on the upper surface of the base plate 1. An inclined plate 4 is slidably mounted on the first fixing rod 2 and the second fixing rod 3. A top plate 5 is also fixedly mounted at the top of the first fixing rod 2 and the second fixing rod 3. The surface of the inclined plate 4 has multiple through holes 6 evenly distributed to facilitate heat conduction and drainage of water accumulated during the thawing of the aquatic foods. A heating mechanism is arranged between the base plate 1 and the inclined plate 4 to transfer heat to the food. An elastic adjustment mechanism is also installed on the base plate 1 and the top plate 5. This elastic adjustment mechanism is divided into multiple parts, used for food vibration and ice crushing, respectively, to improve the thawing effect.

[0030] In the specific implementation of this embodiment, the thawing process of aquatic food can be effectively accelerated. During thawing, not only can the contact area between hot air and food be increased, but the ice attached to the surface can also be automatically knocked during the melting process of the food to achieve rapid thawing of frozen aquatic products.

[0031] In one embodiment of this utility model, casters may be arranged at the bottom end of the base plate 1 as needed to facilitate the movement of the defrosting device during actual use.

[0032] like Figure 1 As shown, in a preferred embodiment of the present invention, the heating mechanism includes a heating box 7, an air guide pipe 8, a bottom frame 9, and a drain pipe 10;

[0033] The heating box 7 is fixedly installed on the base plate 1, and the top of the heating box 7 is connected to the air guide pipe 8;

[0034] The air duct 8 is also connected to the bottom frame 9 arranged at the bottom end of the inclined plate 4, and a drain pipe 10 is installed at the bottom end of the bottom frame 9.

[0035] In the specific implementation of this embodiment, when it is necessary to thaw aquatic food, the heating box 7 is activated. The heated air flows along the air guide pipe 8 into the bottom frame 9, and finally passes through the through hole 6 provided on the inclined plate 4 to contact the food, so as to accelerate the thawing process.

[0036] like Figure 1 and Figure 2 As shown, in another preferred embodiment of the present invention, the elastic adjustment mechanism includes a support frame 11, a shaped wheel 12, and an elastic support member 16.

[0037] The support frame 11 is fixedly installed on the upper surface of the base plate 1, and a special-shaped wheel 12 is rotatably installed on the top of the support frame 11, and the special-shaped wheel 12 abuts against the bottom frame 9.

[0038] The irregularly shaped wheel 12 is driven by a separate external motor;

[0039] Two elastic support members 16 are provided, which are respectively sleeved on the first fixed rod 2 and the second fixed rod 3. Their top ends are connected to the inclined plate 4 so as to cooperate with the irregular wheel 12 to push the inclined plate 4 to vibrate along the first fixed rod 2 and the second fixed rod 3.

[0040] In the specific implementation of this embodiment, the irregularly shaped wheel 12 rotates under the drive of an external motor. During the rotation, the irregularly shaped wheel 12 continuously pushes the bottom frame 9 and the inclined plate 4 to slide along the fixed rod 2 and the fixed rod 3. During the sliding of the inclined plate 4, the elastic support member 16 undergoes elastic deformation under force, which allows the frozen food to jump, thereby increasing the contact area with hot air.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, in another preferred embodiment of the present invention, the elastic adjustment mechanism further includes a second irregular wheel 13, a push plate 17, an impact rod 18, and a second elastic support member 19.

[0042] The irregularly shaped wheel 13 is rotatably mounted on the top plate 5;

[0043] Multiple impact rods 18 are provided, and each impact rod 18 is slidably connected to the side plate installed on the first fixed rod 2 and the second fixed rod 3.

[0044] A push plate 17 is fixedly installed at the top of the impact rod 18. The push plate 17 abuts against the irregular wheel 13. An elastic support member 19 connected to the push plate 17 is also sleeved on the impact rod 18.

[0045] In the specific implementation of this embodiment, the irregularly shaped wheel 13 applies a force to the push plate 17 when it rotates along the top plate 5. The push plate 17 pushes the impact rods 18 at multiple positions to slide along the side plate. The impact rods 18 continuously strike the frozen aquatic food during the movement.

[0046] like Figure 1 As shown, in another preferred embodiment of the present invention, the impact rod 18 is made of rubber material to avoid damaging the surface of the food upon contact.

[0047] In the specific implementation of this embodiment, pulleys 14 are installed on the shaft ends of both the first irregular wheel 12 and the second irregular wheel 13, and adjacent pulleys 14 are connected by a synchronous belt 15.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0049] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
