Description

Technical Field

[0001] This utility model belongs to the field of quick-freezing and preservation equipment, and specifically relates to an immersion quick-freezing and freshness-locking device. Background Technology

[0002] Immersion quick-freezing equipment is a technology that rapidly freezes food by directly immersing it in a low-temperature liquid medium. It is a new and efficient low-temperature processing technology. Compared with traditional freezing methods, immersion quick-freezing technology has advantages such as faster freezing speed, shorter freezing time, and the ability to obtain high-quality products; lower energy consumption, reducing equipment investment; high thermal conductivity of the freezing medium, resulting in high heat transfer efficiency; no need to maintain a high flow rate of cold air; and the lowest cost compared to air freezing and liquid nitrogen freezing. It can achieve individual quick-freezing, allowing for better separation of individual food items during processing; the fast freezing rate results in fine ice crystals that are evenly distributed within cells and intercellular spaces, minimizing juice loss during thawing; and it better preserves the original texture, taste, and appearance of the food, significantly improving the quality of cold-processed food. With the continuous improvement of people's living standards and changes in dietary habits, the requirements for food preservation are becoming increasingly stringent, indicating a broad prospect for the development and application of this technology.

[0003] Currently, the most common types of equipment on the market are liquid nitrogen impregnation freezers, alcohol impregnation freezers, and tunnel-type continuous impregnation equipment. They share common characteristics such as complex structure, high manufacturing cost, difficulty in recycling and reusing lost refrigerant, high energy consumption, and complicated installation and maintenance. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose an immersion quick-freezing and freshness-locking device, which has a simple and novel structure, is energy-saving and environmentally friendly, easy to operate and learn, has good heat preservation effect, fast cooling speed, small space occupation, and convenient installation and adjustment.

[0005] This utility model is achieved through the following technical solution: An immersion-type quick-freezing and freshness-locking device includes an immersion quick-freezing chamber 1 and a compression cooling unit. The immersion quick-freezing chamber is filled with coolant and has a baffle that divides it into a cooling pool and an immersion pool. The cooling pool and the immersion pool are connected by a coolant circulation hole. The immersion pool is divided into three sections from left to right: a feeding section, a working section, and a discharging section. A driving mechanism is installed on the working section. The driving mechanism includes chain drive shafts at both ends of the working section, a drive chain between the two chain drive shafts, and a hook on the drive chain. One chain drive shaft is connected to a drive mechanism. A circulating water pump is installed in the cooling pool. The feed pipe of the circulating water pump in the feeding section is located in the cooling pool, and the discharge pipe of the circulating water pump is located at the inlet of the immersion pool. The compression cooling unit is connected to a refrigerant circulation pipe, which is also connected to the compression cooling unit. The body of the refrigerant circulation pipe is located in the cooling pool.

[0006] Preferably, the impregnation tank is provided with a horizontally arranged isolation plate, which is located in the ring formed by the transmission chain.

[0007] Preferably, there are multiple hooks, which are evenly distributed on the transmission chain.

[0008] Preferably, the refrigerant circulation pipe has four pipes, which are connected end to end to form a U-shape, and the discharge end and the feed end are connected to the compression cooling unit.

[0009] Preferably, the discharge pipe of the circulating water pump has a bend section, and the outlet of the discharge pipe has a duckbill shape.

[0011] Preferably, the end of the immersion quick-freezing box is connected to a material tank, and a centrifugal dehydration cylinder is provided below the outlet of the material tank.

[0012] Preferably, the material trough includes a horizontal trough section and an inclined trough section connected to each other.

[0013] Preferably, both the impregnation quick-freezing box body and the box lid are provided with an insulation layer.

[0014] Preferably, the connection between the feed pipe, the discharge pipe and the circulating water pump is a quick-clamp type chuck connection.

[0015] This invention features an immersion quick-freezing chamber for holding refrigerant. The refrigerant in the immersion tank is continuously circulated through an inlet pipe, a circulating water pump, and an outlet pipe. A compression cooling unit continuously circulates the refrigerant through a refrigerant circulation pipe, cooling the refrigerant passing through the cooling tank during the circulation process, thus maintaining the temperature of the refrigerant in the immersion tank. In the feeding section, the food to be quick-frozen is hung on hooks, and a transmission chain drags the food into the refrigerant in the working section. The food is quick-frozen during its movement in the refrigerant, thus completing the quick-freezing process. The quick-frozen food is removed in the outlet section and then enters a centrifugal dehydrator through a material trough for dehydration. It is simple and convenient to use, and the immersion quick-freezing chamber not only has good heat preservation but also provides excellent energy-saving performance due to the continuous circulation of the refrigerant.

[0018] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1 , Figure 2 As shown, an immersion-type quick-freezing and freshness-locking device includes an immersion quick-freezing chamber 01 and a compression cooling unit 03. The immersion quick-freezing chamber is filled with coolant. A baffle divides the immersion quick-freezing chamber into an immersion pool 10 and a cooling pool 11. The immersion pool is provided with coolant circulation holes 106 that communicate with the cooling pool. The immersion pool is used for quick-freezing food that needs to be quick-frozen, and the cooling pool is used for the refrigerant to cool the coolant and maintain the cooling temperature. The top of the immersion quick-freezing chamber is provided with a cover 02, which is fixed with a locking fastener 105 for easy opening of the immersion quick-freezing chamber. The bottom of the immersion quick-freezing chamber is provided with support feet 104 for easy movement of the immersion quick-freezing chamber. Both the immersion quick-freezing chamber and the cover are provided with an insulation layer 100 to enhance the cooling effect.

[0020] The immersion tank 10 is divided into three sections from left to right: a feeding section 101, a working section 102, and a discharging section 103. A dragging mechanism 12 is installed above the working section. Food to be quick-frozen is placed on the dragging mechanism in the feeding section, and the dragging mechanism pulls the food into the working section, where it is completely submerged in the coolant. The dragging mechanism then pulls the quick-frozen food to the discharging section, where it is removed. The dragging mechanism includes chain drive shafts at both ends of the working section, with a drive chain 111 between the two shafts. Multiple hooks 114 are evenly distributed on the drive chain and are used to hold the food to be quick-frozen or baskets that hold the food. One chain drive shaft is connected to a drive mechanism 112, which drives the chain drive shaft to rotate, thus running the drive chain. In operation, the immersion tank contains a refrigerant solution. Food items requiring quick-freezing are hung on hooks at the feeding section. As the conveyor chain runs, it drags the food into the refrigerant solution in the working section, where it moves within the solution, thus quick-freezing the food. Once quick-frozen, the food is removed from the discharge section. The food is placed into the immersion tank from one end and removed from the other, completing the quick-freezing process.

[0021] A circulating water pump 20 is installed in the cooling tank. The feed pipe of the circulating water pump is located in the cooling tank, and the discharge pipe of the circulating water pump is located in the feed section of the impregnation tank. A refrigerant circulation pipe is connected to the compressor cooling unit 03, and the refrigerant circulation pipe body is located in the cooling tank. A coolant circulation hole 106 is located in the discharge section of the impregnation tank. In the cooling tank, the inlet of the feed pipe of the circulating water pump and the coolant circulation hole are located at opposite ends of the refrigerant circulation pipe body. The coolant in the impregnation tank flows into the cooling tank through the coolant circulation hole. After being cooled by the refrigerant in the refrigerant circulation pipe, it enters the impregnation tank through the feed pipe of the circulating water pump, the circulating water pump, and the discharge pipe. The coolant sequentially passes through the feed section, the working section, and the discharge section before entering the cooling tank through the coolant circulation hole. After being cooled by the refrigerant circulation pipe, it is pumped back into the impregnation tank, forming a repeated cycle. The compressor-cooling unit continuously circulates the refrigerant through the refrigerant circulation pipes, constantly cooling the coolant passing through the cooling tank during the circulation process, thereby maintaining the temperature of the coolant in the impregnation tank. The compressor-cooling unit is equipped with a cooling fan 31 for heat dissipation. Preferably, there are four refrigerant circulation pipes, which are connected end to end to form a U-shape, increasing the contact area between the coolant and the refrigerant circulation pipes, which is beneficial for cooling the coolant and improving cooling efficiency. The discharge pipe of the circulating water pump has a bend section, and the outlet of the discharge pipe has a duckbill shape. This structure facilitates the generation of a large impact force when discharging the liquid, which enhances the fluidity of the coolant in the impregnation tank.

[0022] The drive mechanism 112 includes a drive motor and a reducer. The reducer is connected to the chain drive shaft, and the drive motor can drive the chain drive shaft to rotate through the reducer. The reducer can be directly connected to the chain drive shaft or connected through a transmission mechanism. Preferably, the feed section has a driven shaft and the discharge section has a drive shaft. The driven shaft 110 and the drive shaft 115 are connected by an annular chain, and the hook 114 faces the opposite direction of the annular chain's movement.

[0023] The immersion tank is equipped with horizontally arranged isolation plates 113, which are located in the ring formed by the transmission chain. The freezing liquid in the immersion tank is generally higher than the isolation plates. During quick freezing, the isolation plates can prevent food from floating on the liquid surface, thereby ensuring the quick freezing effect.

[0024] The immersion tank 1 is connected to a material tank 402 at one end, and a centrifugal dehydration cylinder 401 is located below the outlet of the material tank. The material tank includes a horizontal section and an inclined section connected together. The quick-frozen food is placed in the material tank and pushed into the centrifugal dehydration cylinder. The centrifugal dehydration cylinder dehydrates the food, removing adhering coolant, thus ensuring a dry surface and preventing waste of coolant. This structure saves space, is compact, and reduces labor costs.

[0025] Preferably, the inlet pipe, outlet pipe and circulating water pump are connected by quick-clamp type 116 clamps, which are quick and easy to install and maintain.

[0026] The working process of this utility model is as follows: Before the equipment operates, refrigerant is added to the immersion tank. During operation, the compressor refrigeration unit cools the refrigerant circulating in the refrigerant circulation pipe, ensuring that the refrigerant reaches the required set temperature. The drive mechanism drives the chain drive shaft to rotate, causing the transmission chain to run and the ring chain to circulate. The material to be quick-frozen and fresh-locked is fed into the feeding section via material bags, material baskets, or directly suspended on hooks evenly arranged on the ring chain. The material is carried into the working section by the running ring chain to achieve the quick-freezing and fresh-locking effect. Because a partition plate is set in the middle of the ring chain, the material is affected by the partition plate during operation, thus preventing the material from floating out of the refrigerant and affecting the effect. When the material reaches the discharge section, the material will automatically detach from the hook due to the direction of the hook, allowing for easy and quick removal of the processed material. The removed material is placed in the material tank and automatically slides into the centrifugal dehydrator for dehydration to complete the quick-freezing process. The centrifugal dehydrator dehydrates the food and removes the adhering refrigerant, after which the food enters the subsequent process. Existing general-purpose equipment can be used for the compressor refrigeration unit and the centrifugal dehydrator.
