Description

TECHNICAL FIELD

[0001] The utility model relates to low temperature drying box technical field, and concretely relates to low temperature drying box of industrial hemp seed. BACKGROUND

[0002] The quality of industrial hemp seed has a vital influence on the planting of industrial hemp and the quality of subsequent products, and the industrial hemp seed contains a certain amount of oil and other components, which is prone to oxidation and deterioration of the oil in the seed under conventional drying conditions, especially high-temperature drying, thereby affecting the germination rate and vitality of the seed. At the same time, if the moisture content of the industrial hemp seed is too high during storage, it is easy to be invaded by mold and other microorganisms, resulting in seed mold. In order to achieve better drying and preservation effect of industrial hemp seed, a low-temperature drying box is usually used to dry and preserve the industrial hemp seed at low temperature.

[0003] The low-temperature drying box is mainly used for drying the articles at a relatively low temperature. Its core principle is to lower the temperature in the box body, so that the water in the articles vaporizes at a lower temperature, and at the same time, the vaporized water vapor is discharged outside the box in time through a ventilation system or a vacuum environment, thereby achieving the purpose of drying. Unlike the conventional high-temperature drying method, low-temperature drying can effectively avoid the damage and denaturation of the articles caused by high temperature, and is particularly suitable for temperature-sensitive substances.

[0004] However, most low-temperature drying boxes lack corresponding air inlet assemblies during actual use, and can only rely on the flow of water vapor to achieve water discharge. When water discharge is performed by relying on the flow of water vapor, the drying efficiency is slow, which is not conducive to promoting the rapid discharge of water vapor. In addition, although some low-temperature drying boxes are provided with air inlet assemblies, the pipelines of the air inlet assemblies are arranged at the bottom wall of the low-temperature drying box, and the openings of the pipelines are arranged upward. During the subsequent drying process, heavy impurities are prone to falling into the pipelines and are difficult to clean, which brings inconvenience to the user. In view of this, the low-temperature drying box for industrial hemp seed is proposed. UTILITY MODEL CONTENT
