Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of cold chain equipment, and specifically relates to a high-efficiency dehumidifying and drying equipment for a low-temperature environment in a cold chain equipment. BACKGROUND

[0002] A cold chain equipment is a functional equipment group that creates and maintains a specific low-temperature / constant-temperature environment through artificial refrigeration technology, and its core function is to ensure the quality safety and circulation efficiency of temperature-sensitive goods in the whole supply chain. It is mainly used for food preservation, medicine and precision material protection, etc. The low-temperature environment in the cold chain equipment is prone to high humidity problems (for example, ginseng tablets stored in the low-temperature environment in the cold chain equipment are prone to bacterial growth and rot in a high-humidity environment), and a dehumidifying and drying equipment is usually needed to dehumidify and dry the goods in the cold chain to prevent the goods from being damaged by moisture.

[0003] In the prior art, a circulating low-temperature drying machine and a circulating low-temperature drying method are disclosed (publication number: CN118935944A), which mainly circulates and dehumidifies the inside of a target piece through two groups of dehumidifying components. When the dehumidifying pipeline of any dehumidifying component fails, the dehumidifying component enters a drying program, that is, external air enters the dehumidifying pipe group and dries the dehumidifying material of the dehumidifying pipeline. After the dehumidifying effect of the dehumidifying pipeline is restored, the dehumidifying component returns to the circulating dehumidification state of the inside of the target piece. During the drying program of the dehumidifying component, the other dehumidifying component maintains the circulating dehumidification of the inside of the target piece, ensuring that the circulating dehumidification of the inside of the target piece is uninterrupted, that is, dry gas can continue to be circulated into the inside of the target piece, so that effective dehydration and drying of the goods in the inside of the target piece can be achieved without the need for heating the gas, and the practicability is good.

[0004] However, there are still corresponding disadvantages in actual use: when dehumidifying and drying ginseng tablets, the ginseng tablets are usually laid flat on the bottom surface of the cabinet, and the above-mentioned patent uses dry gas to enter the cabinet from the lower part and is discharged from the upper part, and the gas flow direction is from bottom to top. When the gas flows, it blows through the air vents to the bottom of the ginseng tablets laid on the partition to dehumidify and dry them. The bottom surface of the ginseng tablets has a large amount of contact with the gas flow, the upper surface of the ginseng tablets has a small amount of contact with the gas flow, and the ginseng tablets have a certain thickness, which leads to poor dehumidifying and drying efficiency and effect, long time consumption, and easy increase of energy consumption of the equipment, and low economic efficiency.
