Description

Technical Field

[0001] This utility model belongs to the field of quick-freezing and preservation equipment, and specifically relates to a novel immersion-type quick-freezing and preservation equipment. Background Technology

[0002] Quick-freezing fresh food results in small ice crystals that are evenly distributed within the cells and intercellular spaces. This minimizes juice loss during thawing and helps maintain the original texture, taste, and appearance of the food. It also significantly improves the quality of cold-processed food. As a result, more and more equipment for quick-freezing food is appearing on the market in pursuit of increasingly better quick-freezing effects.

[0003] Currently, the main equipment for quick-frozen foods includes liquid nitrogen immersion freezers, alcohol immersion freezers, and tunnel-type continuous immersion equipment. These devices generally have complex structures, high manufacturing costs, and difficulties in recycling and reusing lost refrigerant. They also have high energy consumption, and the installation and maintenance during use are relatively complicated, which is not conducive to their widespread use. Utility Model Content

[0004] To overcome the shortcomings and problems of existing technologies, this utility model provides a novel immersion-type quick-freezing and freshness-locking device, which features a simple and novel structure and is energy-saving and environmentally friendly.

[0005] This utility model is achieved through the following technical solution: A novel immersion-type quick-freezing and freshness-locking device includes a quick-freezing chamber and a compression cooling unit. Both ends of the quick-freezing chamber are equipped with chain drive shafts, and a drive chain is provided between the two chain drive shafts. A hook is provided on the drive chain. One chain drive shaft is connected to a drive mechanism. One end of the quick-freezing chamber is connected to an inlet pipe and an outlet pipe. The inlet pipe enters from one end of the quick-freezing chamber and extends to the other end of the chamber's internal cavity. A circulating water pump is provided between the inlet pipe and the outlet pipe. The compression cooling unit is connected to cooling circulation pipes, all of which are connected to the compression cooling unit. The cooling circulation pipes are inserted into the inlet pipe and extend within it.

[0006] The quick-freezing chamber is equipped with horizontally arranged isolation plates, which are located in the ring formed by the transmission chain.

[0007] The hooks are provided in multiples and are evenly distributed on the transmission chain.

[0008] The water inlet pipes are provided in two places, located on both sides of the quick-freezing box. The circulating water pump is connected to the two water inlet pipes through a three-way connecting pipe.

[0009] The water inlet pipe has a bend at the outlet and a flat opening at the outlet.

[0010] The top of the quick-freezing box is provided with a cover, which is fixed with a locking fastener, and the bottom of the quick-freezing box is provided with support feet.

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

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

[0013] This invention features a quick-freezing chamber for holding refrigerant. The refrigerant circulates continuously through a return pipe, a circulating water pump, and an inlet pipe. A compression cooling unit continuously circulates the refrigerant through the cooling circulation pipe, cooling the refrigerant passing through the inlet pipe during the circulation process, thus maintaining the temperature of the refrigerant inside the quick-freezing chamber. Foods requiring quick-freezing are hung on hooks, and a transmission chain pulls the food into the refrigerant, where it is quick-frozen. This process is simple and convenient to use, and the quick-freezing chamber not only has good insulation but also provides excellent energy savings due to the continuous circulation of the refrigerant.

Detailed Implementation

[0016] 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.

[0017] like Figure 1-5 As shown, a novel immersion-type quick-freezing and freshness-locking device includes a quick-freezing chamber 1 and a compression cooling unit 2. The quick-freezing chamber 1 is placed in a freezing liquid. The top of the quick-freezing chamber 1 is provided with a cover 11, which is fixed by a locking fastener 12 for easy opening of the quick-freezing chamber 1. The bottom of the quick-freezing chamber 1 is provided with support feet 13 for easy movement of the quick-freezing chamber 1.

[0018] The quick-freezing chamber 1 has chain drive shafts 3 at both ends, with a drive chain 4 between the two chain drive shafts 3. Multiple hooks 5 are evenly distributed on the drive chain 4 and are used to hang food items to be quick-frozen or baskets containing food. One chain drive shaft 3 is connected to a drive mechanism, which drives the chain drive shaft 3 to rotate, thus running the drive chain 4. In use, the quick-freezing chamber 1 contains freezing liquid. The food items to be quick-frozen are hung on the hooks 5. As the drive chain 4 runs, it drags the food into the freezing liquid and moves it within the liquid, thus quick-freezing the food. The food is placed in from one end of the quick-freezing chamber 1 and removed from the other end, completing the quick-freezing process. The drive mechanism may include a drive motor and a reducer. The reducer is connected to the chain drive shaft 3, and the drive motor drives the chain drive shaft 3 to rotate through the reducer. The reducer can be directly connected to the chain drive shaft 3 or connected through a drive mechanism. The quick-freezing chamber 1 is equipped with a horizontally arranged partition plate 6, which is located in the ring formed by the transmission chain 4. The freezing liquid in the quick-freezing chamber 1 is generally higher than the partition plate 6. During quick-freezing, the partition plate 6 can prevent food from floating on the liquid surface, thereby ensuring the quick-freezing effect.

[0019] One end of the quick-freezing chamber 1 is connected to an inlet pipe 7 and a return pipe 8. The inlet pipe 7 enters from one end of the quick-freezing chamber 1 and extends to the other end of the inner cavity of the quick-freezing chamber 1, allowing the coolant to enter from one end and flow out from the other end, forming a circulation. A circulating water pump 9 is installed between the inlet pipe 7 and the return pipe 8 to facilitate the return coolant to circulate back into the quick-freezing chamber 1, thus forming repeated circulation. There are two inlet pipes 7, distributed on both sides of the quick-freezing chamber 1. The circulating water pump 9 is connected to the two inlet pipes 7 through a three-way connecting pipe 10. This structure makes the coolant entering the quick-freezing chamber 1 more even, facilitating the formation of a more uniform temperature environment inside. The outlet end of the inlet pipe 7 has a bend section 71, and the outlet has a flat opening 72. This structure facilitates the formation of a larger jet of liquid upon discharge, enhancing the flow of coolant within the quick-freezing chamber 1.

[0020] The compressor cooling unit 2 is connected to a cooling circulation pipe 21. All cooling circulation pipes 21 are connected to the compressor cooling unit 2, and the pipe body of the cooling circulation pipe 21 is inserted into the water inlet pipe 7 and extends therein. The compressor cooling unit 2 causes the refrigerant to circulate continuously through the cooling circulation pipe 21, and during the circulation process, it continuously cools the coolant passing through the water inlet pipe 7, thereby ensuring the temperature of the refrigerant in the quick-freezing chamber 1.

[0021] The end of the quick-freezing box 1 is connected to a material trough 14, and a centrifugal dehydration cylinder 15 is provided below the outlet of the material trough 14. The material trough 14 includes a horizontal trough 141 and an inclined trough 142 connected to each other. Quick-frozen food is placed into the material trough 14 and pushed into the centrifugal dehydration cylinder 15. The centrifugal dehydration cylinder 15 dehydrates the food and removes the adhering coolant, so that the food surface is dry and the coolant is not wasted.

[0022] The working process of this utility model is as follows: When the equipment is running, the coolant in the quick-freezing chamber 1 flows out through the return pipe 8, passes through the circulating water pump 9, and then flows back into the quick-freezing chamber 1 through the inlet pipe 7, forming a circulation. During the circulation process, the compression cooling unit 2 causes the refrigerant to continuously circulate through the cooling circulation pipe 21, continuously cooling the coolant passing through the inlet pipe 7, thereby ensuring the temperature of the freezing liquid in the quick-freezing chamber 1. When quick-freezing food, the food is hung on the hook 5 at one end of the quick-freezing chamber 1. The drive mechanism drives the chain drive shaft 3 to rotate, causing the drive chain 4 to run. As the drive chain 4 runs, it drags the food into the freezing liquid and moves within the freezing liquid, thereby quick-freezing the food. When the food moves to the other end of the quick-freezing chamber 1, the quick-freezing is complete. The food is then removed and placed in the material tank 14, and pushed into the centrifugal dehydration drum 15. The centrifugal dehydration drum 15 dehydrates the food, removing the adhering coolant, and the food can then be removed.

[0023] The above embodiments are preferred implementations of this utility model and are not intended to limit this utility model. Any obvious substitutions are within the protection scope of this utility model without departing from its inventive concept.
