[0003] For example, the Chinese patent technical document with the announcement number CN219640520U discloses a double-spiral quick-freezing device for improving refrigeration efficiency, including a drive assembly, and a first spiral quick-freezing group and a second spiral quick-freezing group synchronously driven by the drive assembly. The first spiral quick-freezing group and the second spiral quick-freezing group are both arranged in the machine cover. The first spiral quick-freezing group includes a rotating drum and a spiral conveyor chain. The outer cylinder wall of the rotating drum is provided with a spiral material channel. The upper end of the machine cover is provided with a cold supply pipe group. The cold supply pipe group is provided with a number of cold supply branches. The cold supply branches face the spiral material channel at the outer cylinder wall of the rotating drum. The support beam at the upper end of the rotating drum is fixed with a blade member, and the lower end of the rotating drum is provided with a guide groove; the structure of the second spiral quick-freezing group is the same as that of the first spiral quick-freezing group.

[0004] In the above technical solution, cold air is transported to the periphery of the transfer drum through the cold delivery pipe group, and combined with the blade members at the upper end and the guide grooves at the lower end of the transfer drum, the air circulation inside the drum cavity and outside the drum wall of the transfer drum is accelerated, thereby improving the refrigeration efficiency. In the above technical solution, the food is mainly fed into the first spiral quick-freezing group and the second spiral quick-freezing group respectively through the first feeding port and the second feeding port. However, the first feeding port and the second feeding port are independent of each other, so it is necessary to feed the food into the first feeding port and the second feeding port respectively, which causes certain inconveniences when feeding the food. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a double-spiral quick-freezing device for food processing, which can make food feeding more convenient.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a double-spiral quick-freezing device for food processing, comprising a machine bin, wherein an installation cavity is provided in the machine bin, a symmetrically arranged central rotating drum is provided in the installation cavity, the central rotating drum is rotatably connected to the installation cavity in a vertical direction, the outer periphery of the central rotating drum is provided with a material channel distributed along a spiral, a driving device and a cold delivery pipe are provided above the machine bin, the driving device is used to drive the central rotating drum on both sides to rotate synchronously, and the cold delivery pipe is used to deliver cold air into the installation cavity, the machine bin is symmetrically provided with material openings opposite to the central rotating drum on both sides, and a first material distribution conveyor belt, a second material distribution conveyor belt and a converging conveyor belt are provided on the outside of the machine bin, one end of the first material distribution conveyor belt and the second material distribution conveyor belt respectively correspond to the material opening, and the other end extends to the bottom of the converging conveyor belt respectively, and a material distribution device is provided above the converging conveyor belt, and the material distribution device is used to guide the food delivered by the converging conveyor belt to the first material distribution conveyor belt and the second material distribution conveyor belt respectively.

[0007] The utility model is further configured as follows: the material distribution device includes a frame located above the converging conveyor belt, a driving cylinder is rotatably connected to the frame, one end of the frame extends outward as a connecting part, a connecting rod is provided on the connecting part, a rotatable connecting seat is sleeved on the outer periphery of the connecting rod, and extensions extending outward are provided on both sides of the connecting seat, the extensions are rotatably connected to a connecting frame, and the connecting frame is located at an end away from the extension and extends downward as a mounting end, and an arc-shaped baffle is fixed to the mounting end, and the arc-shaped baffles on both sides are used to guide food to the first material distribution conveyor belt and the second material distribution conveyor belt respectively.

[0008] The utility model is further configured as follows: a material guide plate is fixed to the inner wall of the machine bin, one end of the material guide plate is connected to the material port, and the other end extends toward the material channel, and the height of the material guide plate decreases successively along the direction from the material port toward the material channel to form an inclined guide side wall.

[0009] The utility model is further configured as follows: the driving device includes a driving motor, the top of the rotating drum is provided with a connecting end extending outside the machine chamber, a transmission gear is fixedly mounted on the outer periphery of the connecting end, a transmission chain is mounted between the transmission gears on both sides, and the driving motor is connected to one side of the connecting end.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] Since the first material distribution conveyor belt, the second material distribution conveyor belt and the converging conveyor belt are provided, and the material distribution device is provided above the converging conveyor belt, when it is necessary to put the food into the material channel of the rotating drum on both sides for freezing, it is only necessary to put the food directly into the converging conveyor belt, and the converging conveyor belt will convey the food to the first material distribution conveyor belt and the second material distribution conveyor belt. During the conveying process, the material distribution device can guide the food sent out by the converging conveyor belt to the first material distribution conveyor belt and the second material distribution conveyor belt respectively. In this way, the food can be respectively sent to the material channels on both sides through the first material distribution conveyor belt and the second material distribution conveyor belt. Therefore, it effectively solves the technical problem in the prior art that the first feeding port and the second feeding port are independent of each other, and therefore the food needs to be put into the first feeding port and the second feeding port respectively before the food can be sent to the material channels on both sides, resulting in inconvenient food feeding. Therefore, it can make food feeding more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
