Intelligent fresh-keeping and humidifying air source heat pump drying chamber

Abstract

The invention relates to the fields of air energy heat pump tobacco leaf drying, tobacco leaf humidifying and moisture regaining and the like, in particular to an intelligent fresh-keeping and humidifying air source heat pump drying chamber. An air source heat pump is arranged at the front end of the drying chamber, the drying chamber comprises a first cavity and a second cavity, a partition plateis arranged between the first cavity and the second cavity, a fan, a heat exchanger and a fresh air valve are arranged in the first cavity, the second cavity is provided with a placing rack, a getterpump is arranged above the placing rack, a humidifying mechanism is arranged in the second cavity, a water pipe in the humidifying mechanism is connected to a high-pressure atomizing pump outside thedrying chamber, by using the drying chamber, tobacco leaves can be dried, tobacco leaf yellowing can be accelerated in the tobacco leaf drying process, tobacco leaves can be humidified and dampened after being dried, the freshness of the tobacco leaves can be guaranteed in the tobacco leaf humidifying and moisture regaining process, the tobacco leaf quality is improved, the income of tobacco growers is increased, an air source heat pump is adopted, energy consumption is reduced, and the drying chamber is green and environmentally friendly.

Description

Technical field: [0001] The invention relates to the technical fields of air source heat pump drying of tobacco leaves, humidification and rehydration of tobacco leaves, cold storage and preservation of agricultural products, and in particular to an air source heat pump drying room with intelligent freshness preservation and humidification. Background technique: [0002] Tobacco leaves need to be dried after they are picked. At present, there are two ways for tobacco farmers to dry tobacco leaves. The first is natural drying, but it is too time-consuming and requires a large enough site. Because of the weather, the tobacco leaves cannot be dried naturally; the second is to use a heat pump dryer to dry the tobacco leaves. The heat pump dryer uses the reverse Carnot principle to absorb the heat of the air and transfer it to the drying room. In order to realize the drying of tobacco leaves, the drying efficiency of tobacco leaves is greatly improved. However, the existing heat ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problem that the heat pump dryer can only dry the tobacco leaves but cannot humidify and rehydrate the tobacco leaves, the present invention provides an air source heat pump drying room with intelligent freshness preservation and humidification, which uses the air source heat pump as the energy output, saving energy costs, and It reduces pollution and is environmentally friendly. It can not only dry and dry the tobacco leaves, but also humidify and rehydrate the tobacco leaves after the tobacco leaves are dried. The drying room dries the tobacco leaves again, which is convenient to use and improves the quality of the tobacco leaves, and the second chamber can also store the dried tobacco leaves. The tobacco leaves are divided into partitions through the rotating shelf composed of moving walls. When the demand for tobacco leaves is small , you can only humidify and rehydrate the tobacco leaves in a certain partition and then take them out. It is not necessary to humidify and rehydrate all the tobacco leaves
