Description

Technical Field

[0001] The utility model relates to a pork quick-freezing and fresh-keeping device. Background Art

[0002] After slaughtering pigs, the pork needs to be quickly frozen within 2 hours to achieve the purpose of effective preservation. The traditional freezing method is to stack the pigs and push them into the cold storage for freezing. This type of cold storage has large specifications. When the amount of frozen pork is relatively small, it is also necessary to maintain full power operation to ensure the low temperature of the cold storage, so the energy consumption is relatively high.

[0003] Secondly, the stacked pork will stick together after being frozen, and forced separation will cause the pork to be torn, affecting later sales.

[0004] Based on the above problems, we designed a pork quick-freezing and preservation device that can meet small-batch freezing needs. Utility Model Content

[0029] like Figure 1The pork quick-freezing and preservation device shown in the figure includes a refrigeration system, which is equipped with more than two cold rows 1 and also includes an insulation box 2. The more than two cold rows 1 are installed on the two side walls of the insulation box 2. An opening is provided at the front end of the insulation box 2, and a box cover structure 3 is slidably fitted at the opening. A cold preservation device 4 is provided at the bottom of the insulation box 2.

[0030] See also Figure 2 As shown, a cooling plate 21 is provided at the bottom of the heat preservation box 2 , and the cooling plate 21 is inserted into the cold preservation device 4 .

[0031] The cooling fins 21 facilitate the transfer of the cooling energy of the cooling radiator 1 downward to the cooling device 4 .

[0032] See also Figure 1 , Figure 2 and Figure 6 As shown, the cold-keeping device 4 includes a cold-keeping box 401, the size of which is larger than the thermal insulation box 2, an injection pipe 402 for injecting brine is arranged on the top of the cold-keeping box 401, a pipe cover 403 is matched at the pipe mouth of the injection pipe 402, the cooling plate 21 is inserted into the cold-keeping box 401, and an extension plate 441 is arranged at the front end of the cold-keeping box 401, and the box cover structure 3 slides along the extension plate 441.

[0033] In the above technical solution, salt water is injected into the cold preservation box 401, and the salt content of the salt water is adjusted so that the salt water will not freeze at a low temperature of about 30 degrees Celsius. By replacing the cold sheet 21, the cold energy in the working insulation box is transferred to the salt water, so that the salt water is kept at a low temperature, and the insulation box 2 is kept cold. In particular, a longer cold preservation time can be provided during a power outage.

[0034] See also Figure 1 and Figure 6 As shown, a motor 404 is installed on the side of the cold-keeping box 401. The output shaft of the motor 404 is inserted into the cold-keeping box and matched with a stirring rod 405. A bearing and a shaft seal are matched between the output shaft of the motor 404 and the cold-keeping box 401.

[0035] In the above technical solution, the salt water can be fully mixed by the motor 404 and the stirring rod 405, so that the structure of the salt water is more uniform.

[0036] See also Figure 3 , Figure 4 and Figure 5As shown, the box cover structure 3 includes a box cover 301, a connecting plate 302 is provided at the front of the box cover 301, a sliding rod 303 is fixed by the connecting plate 302, sliding sleeves 221 are provided on both sides of the thermal insulation box 2 near the front end, and the sliding rod 303 slides along the sliding sleeves 221, a frame-shaped groove 304 is provided at the rear end of the box cover 301, an electric heating pipe 305 is installed in the groove 304, a thermostat 306 for adjusting the temperature of the electric heating pipe 305 is installed at the front end of the box cover 301, and a sealing cover covering the groove 304 is installed at the rear end of the box cover 301. Ring 307, an oil filling hole corresponding to the groove 304 is arranged on the top of the box cover 301, and a hole plug 377 is detachably matched at the oil filling hole. When the box cover 301 is closed, the sealing ring 307 is sealed between the thermal insulation box 1 and the box cover 301, and the sealing ring 307 is glued and fixed to the box cover 301, and seals the groove 304. On the rear end face of the box cover 301, a plurality of hanging rods 331 are arranged on the inner side of the groove 304, and a roller group 393 is arranged at the front end of the box cover 301, and the roller group 393 rolls along the extension plate 441.

[0037] We found in actual use that the lid of the box that was closed separately would stick to the insulation box due to the low temperature (minus 30 degrees Celsius), and it would be very difficult to open after adhesion.

[0038] Therefore, in the above technical solution, a groove 304 and a sealing ring 307 are provided. When in use, heat transfer oil is injected through the oil filling hole. When the box cover 301 is difficult to open, the heat transfer oil can be heated by the electric heating pipe 305 to heat the sealing ring 307. After heating, the adhesion position is dissolved, and the box cover 301 can be easily opened at this time.

[0039] See also Figure 2 As shown, a first limiting cap 332 is screwed into the end of the sliding rod 303 .

[0040] The first limiting cap 332 is provided to limit the forward sliding movement of the sliding rod 303 to prevent the sliding rod 303 from sliding out.

[0041] See also Figure 3 As shown, a second limiting cap 333 is screwed into the end of the hanging rod 331 .

[0042] When the pork is hung by the hook for quick freezing, the hook is hung on the hanging rod 331 , and the second limiting cap 333 can prevent the hook from sliding off the end of the hanging rod 331 .

[0043] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
