Description

Technical Field

[0001] This utility model relates to the field of liquefaction quick-freezing technology, and in particular to a liquefaction quick-freezing device. Background Technology

[0002] Liquid quick-freezing equipment is a type of specialized equipment that uses a liquid cryogenic medium as the core refrigeration source and achieves rapid freezing of materials through efficient heat exchange. The core principle of this type of equipment is to utilize the huge temperature difference between the liquid medium and the material to be frozen, and to complete the heat transfer in a very short time through direct contact or indirect conduction, so that the core temperature of the material drops rapidly to below the freezing point, thereby avoiding the destruction of the tissue structure caused by slow freezing.

[0003] Liquid quick-freezing equipment is a high-efficiency freezing device that uses a low-temperature liquid medium to directly contact the material and achieve instant freezing of the material through rapid heat absorption. Currently, existing liquid quick-freezing equipment generally has a significant drawback: the lack of a dedicated anti-sticking and separation structure for frozen materials. During the ultra-low temperature freezing process, the surface moisture of the material will quickly condense into ice, and multiple materials are prone to sticking together. Sticking materials increase the workload of subsequent sorting, not only reducing production efficiency but also easily damaging the materials during the sorting process. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a liquid quick-freezing device, which aims to improve the problems of lack of anti-sticking separation and poor spraying effect in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a liquid quick-freezing device, comprising an insulated outer shell, a conveyor belt disposed inside the insulated outer shell, a roller being drivenly connected to the bottom of the conveyor belt, idlers being fixedly connected to both ends of the roller, support legs being fixedly connected to the bottom of the idlers, a motor being fixedly connected to the outer wall of the idlers, a protective shell being fixedly connected to the outer wall of the motor being fixedly connected, a collection box being disposed on the front side of the idlers, an electrical box being fixedly connected to the outer wall of the collection box, a second motor being fixedly connected to the inner wall of the electrical box, a scraper being connected through the output end of the second motor, and a spraying mechanism being disposed on the top of the second motor for comprehensive coverage spraying.

[0006] As a further description of the above technical solution:

[0007] The spraying mechanism includes a support base, an evaporator fixedly connected to the top of the support base, a liquid storage tank fixedly connected to the outer wall of the evaporator, a pipe fixedly connected to the top of the liquid storage tank, a connecting block fixedly connected to the outer wall of the pipe, a retainer fixedly connected to the top of the connecting block, a multi-directional nozzle connected to the bottom of the pipe, a fixing block fixedly connected to the bottom of the multi-directional nozzle, a ball bearing slidably connected to the outer wall of the fixing block, and a fixing shell fixedly connected to the outer wall of the ball bearing.

[0008] As a further description of the above technical solution:

[0009] A water-collecting base is fixedly connected to the bottom of the heat-insulating shell, and a drain outlet is fixedly connected to the outer wall of the water-collecting base.

[0010] As a further description of the above technical solution:

[0011] A support plate is fixedly connected to the outer wall of the water receiving chassis, and a fan casing is provided at the bottom of the support plate.

[0012] As a further description of the above technical solution:

[0013] A mesh cover is fixedly connected to the outer wall of the fan casing, and a fixing seat is fixedly connected to the inner wall of the fan casing.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the fixed base is fixedly connected to a motor three, and the output end of the motor three is fixedly connected to a fan blade.

[0016] As a further description of the above technical solution:

[0017] The outer wall of the fan casing is fixedly connected to a bracket, and the front and rear sides of the water receiving base are fixedly connected to support rods.

[0018] As a further description of the above technical solution:

[0019] An inspection door is rotatably connected to the outer wall of the insulation shell, and a handle is fixedly connected to the outer wall of the inspection door.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the material is first placed on the conveyor belt, and the motor is started to rotate the drum, pushing the material forward. Due to the different moisture content or the characteristics of the material, it is easy to stick to the conveyor belt. By connecting the output end of the motor to the scraper, the scraper rotates in the same direction, which can effectively scrape the material stuck on the conveyor belt into the collection box for unified collection, thereby improving the working efficiency of the machine and saving labor costs.

[0022] 2. In this utility model, the evaporator shortens the quick-freezing time by exchanging heat with the surrounding medium through the pipe wall. The refrigerant in the storage tank is transmitted to the multi-directional nozzle through the pipeline. Affected by the internal air flow, the fan blades rotate around the fixed block. The ball bearings are prevented from slipping by the limiting of the fixed shell. The increased spray area can significantly shorten the freezing time and reduce material damage. At the same time, the fixed connection between the fixture and the heat insulation shell enhances the stability of the structure and reduces the probability of damage. Attached Figure Description

Due to the different moisture content or the characteristics of the material, it is easy to stick to the conveyor belt. The scraper 12 is connected to the output end of the motor 11, so that the scraper 12 rotates in the same direction. This can effectively scrape the material stuck on the conveyor belt 3 into the collection box 9 for collection, which improves the working efficiency of the machine and saves labor costs.
