Description

Technical Field

[0001] The invention belongs to the technical field of refrigeration, and in particular relates to a box-type low-temperature instant freezing device and a working method thereof. Background Art

[0002] The speed of human technological development is geometric, and the importance of advanced refrigeration technology is self-evident. Modern scientific research shows that rapid freezing of food is prone to form a vitreous structure, while traditional freezing will form ice crystals. The formation of ice crystals is the biggest drawback of traditional frozen food. Whether food can be quickly frozen directly determines whether the cells inside the food will be frozen and broken, and whether it will turn into zombie meat. In addition to liquid nitrogen freezing, today's rapid freezing also has ultra-low temperature refrigeration, but the energy efficiency ratio of ultra-low temperature refrigeration in the current refrigeration system is still relatively poor and not ideal.

[0003] Box freezers are widely used in the freezing industry because of their simple and flexible operation and the ability to freeze small batches. Existing box freezers generally place food directly into the equipment for cooling when in use, but general refrigeration methods cannot quickly cool food in a short period of time, which affects the quality of the food after cooling. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the existing box-type freezing equipment generally puts the food directly into the equipment for cooling when in use, and the general refrigeration method cannot quickly cool the food in a short time, thus affecting the quality of the cooled food, and proposes a box-type low-temperature instant freezing equipment and its working method.

[0005] In order to achieve the above object, the present invention adopts the following technical scheme: a box-type low-temperature instant freezing device, comprising a box body, a liquid inlet pipe is installed at the top of the box body, and a liquid outlet pipe is installed at the top of the box body;

[0006] The top of the box is connected to a connecting plate, and one end of the connecting plate is hingedly connected to a mounting plate, one side of the mounting plate is connected to a side door, a screw plate is installed on the surface of the side door, and a hydraulic rod is installed on one side of the box;

[0007] A mounting frame is installed inside the box body, and a fan is installed on one side of the mounting frame, an air guide plate is installed on the surface of the mounting frame, and a placement plate is installed inside the mounting frame, a cargo box is placed on the top of the placement plate, and a refrigeration pipe plate is installed inside the mounting frame;

[0008] The liquid inlet pipe passes through the box body and is connected to a first branch pipe, and the other end of the first branch pipe is connected to a refrigeration fin row pipe;

[0009] The liquid outlet pipe passes through the box body and is connected to a second branch pipe, and the liquid outlet pipe passes through the box body and is connected to a third branch pipe;

[0010] The liquid inlet pipe passes through the box body and is connected with a fourth branch pipe.

[0011] As a further description of the above technical solution:

[0012] The hydraulic rod is connected to the surface of the side door, and the side door is connected to one side of the box body.

[0013] As a further description of the above technical solution:

[0014] The mounting frame is relatively connected to one side of the side door, and the screw plate passes through the side door and is connected to one side of the box body.

[0015] As a further description of the above technical solution:

[0016] The air guide plate is located above the cargo box, and the refrigeration pipe plate is located at the bottom end of the placement plate.

[0017] As a further description of the above technical solution:

[0018] The second branch pipe is connected to one side of the refrigeration fin tube, and the third branch pipe is connected to one side of the refrigeration tube plate.

[0019] As a further description of the above technical solution:

[0020] The fourth branch pipe is connected to the surface of the refrigeration fin tube plate, and the refrigeration fin tube plate is located at the upper and lower ends and the side of the mounting frame.

[0021] As a further description of the above technical solution:

[0022] The surface of the mounting frame is provided with electric heating wires and defrosting wires, and both sides of the side door are provided with heat preservation plates.

[0023] A method for using a box-type low-temperature instant freezing device comprises the following steps:

[0024] S1. Turn the screw plate out from the inside of the box, open the side door, put the food into the cargo box and close the side door, and limit it by the screw plate;

[0025] S2. Install and connect the liquid inlet pipe and the liquid outlet pipe to the refrigeration system outside the box. Through the operation of the refrigeration system, the refrigeration pipe plate and the refrigeration fin pipe can be operated to ensure that they can reach the specified refrigeration capacity. The liquid inlet pipe and the liquid outlet pipe can also be connected to the coolant liquid storage tank outside the box. When refrigeration is needed, the liquid supply pump works, and the refrigeration pipe plate and the refrigeration fin pipe start to refrigerate. Through the operation of the fan inside the box, the wind can be blown to the box, through the refrigeration fin pipe and back to the fan, so as to form a cold air cycle;

[0026] S3. According to the freezing setting time, after the time is up, the screw plate is turned out and the side door is opened, and the frozen food in the cargo box can be taken out. When the side door is frozen, the contact point between the side door and the mounting frame can be defrosted by the operation of the electric heating wire and the defrosting line.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] 1. In the present invention, the refrigeration system can be used to operate the refrigeration pipe plate and the refrigeration fin pipes inside the box body, thereby refrigerating the food inside the cargo box on the mounting rack, and quickly cooling the food, thereby improving the freezing efficiency of the food.

[0029] 2. In the present invention, through the operation of the fan, the wind blown by the fan can be blown toward the cargo box through the air guide plate, which is convenient for cooling the food. At the same time, the cold air blown by the fan passes through the refrigeration fin exhaust pipe and returns to the fan, forming a cold air circulation inside the box, which can significantly increase the freezing speed of the food.

[0030] 3. In the present invention, the contact point between the side door and the mounting frame can be thawed and defrosted by the operation of the electric heating wire and the defrosting wire to prevent freezing, which would cause the side door to be unable to be opened in a short time and affect the quality of the frozen food.
