Description

Technical Field

[0001] The present application relates to the technical field of food processing, and in particular to a device for cooling and drying rice dumplings. Background Art

[0002] In order to facilitate the sale and preservation of food such as zongzi, zongzi and other foods are usually vacuum packed to isolate air and slow down the rate of food spoilage. The steps of vacuum packaging of zongzi are usually to steam, drain, cool, bag, vacuum seal and label for storage.

[0003] Among them, a large number of zongzi can be transported by means of a conveyor belt, and cooled and dried during transportation. For example, the Chinese patent publication number CN207737960U, published on August 17, 2018, is used. The name of the invention is a dough conveyor belt. The application discloses that a conveyor belt and a bellows above the conveyor belt are arranged on a workbench, and a fan is arranged in the bellows. The fan can dry and cool the food on the conveyor belt.

[0004] However, the temperature difference between the rice dumplings after they are steamed and completely cooled is large, and the time required for cooling while transporting them on the conveyor belt is also long. This will make the conveyor belt's transportation journey longer, causing the equipment to occupy a larger area. Utility Model Content

[0005] In order to improve the problem that the rice dumpling cooling and drying equipment occupies a large area due to the conveyor belt cooling method, the present application provides a rice dumpling cooling and drying equipment.

[0006] The present application provides a rice dumpling cooling and drying device, which adopts the following technical solution:

[0007] A rice dumpling cooling and drying device comprises a frame, a conveying roller arranged on the frame and a conveying mesh belt connected to the conveying roller. The conveying mesh belts are provided in plurality and are evenly divided into two groups. The conveying mesh belts in each group are arranged in parallel from bottom to top and convey in the same direction. The conveying directions of the two groups of conveying mesh belts are opposite and they are arranged alternately in sequence. The frame is provided with a driving part for driving a plurality of conveying mesh belts to rotate simultaneously. The frame is also provided with a top-level blowing member facing the top-level conveying mesh belt and a non-top-level blowing member facing the non-top-level conveying mesh belt.

[0008] By adopting the above technical scheme, multiple layers of conveyor belts are staggered in sequence to enable long-distance transportation of rice dumplings in a serpentine path; and each layer is provided with a top-layer blowing piece or a non-top-layer blowing piece to air-dry the rice dumplings, thereby achieving long-distance transportation and cooling without reducing the cooling efficiency, and also reducing the total floor space of the equipment, thereby improving the problem of a large floor space occupied by the rice dumpling cooling and drying equipment caused by the conveyor belt cooling method.

[0013] Optionally, the water retaining eaves includes two interconnected eaves boards, the eaves boards are both inclined, the connection point of the two eaves boards is on the high point side, and the straight line where the connection point of the two eaves boards is located is parallel to the inclination direction of the base plate.

[0014] By adopting the above technical solution, when water flowing down from the upper conveyor belt falls on the eaves board, it can flow to both sides of the blocked ventilation holes under the guidance of the eaves board, thereby reducing the probability of water flowing into the blocked ventilation holes.

[0015] Optionally, the inclination direction of the bottom plate is such that one side along the width direction of the conveyor belt is the low point side.

[0016] By adopting the above technical solution, the distance between the highest point and the lowest point of the bottom plate is made as small as possible, thereby reducing the space occupied by a single water-blocking and air-inducing member, thereby reducing the space occupied by the equipment.
