Multipurpose heat pump curing barn

Abstract

The invention relates to a multipurpose heat pump curing barn. The curing barn comprises an air energy heat pump and a barn body, wherein the interior of the barn body is separated into a unit chamberand a hot air chamber; an evaporator case of the air energy heat pump is located outdoors, a condenser is located in the unit chamber, a circulating fan is arranged below the condenser, an air guidefan and a residual hot air box are arranged on the two sides of an evaporator in the evaporator case correspondingly, and a movable heat insulation plate is arranged between the air guide fan and theevaporator; and an air supply cavity and a moisture discharge cavity are formed in the top and the bottom of the hot air chamber respectively, the air inlet of the air supply cavity is located in theunit chamber, a circulating air port is formed in the bottom of the side wall, close to the unit chamber, of the hot air chamber, and an air outlet of the moisture discharge cavity is connected with the residual hot air box through a moisture discharge fan. The curing barn is suitable for drying various crops, and can effectively protect moisture removal gas against invalid heat dissipation in thedischarge process at the same time, so that the heat of the moisture removal gas can be sufficiently absorbed by the evaporator of the air energy heat pump to a maximum extent, and the heat energy utilization rate is improved.

Description

technical field [0001] The invention belongs to the field of agricultural processing devices, in particular to a multipurpose heat pump barn. Background technique [0002] After the tobacco leaves of flue-cured tobacco varieties are harvested from the field, they need to be roasted and prepared before they can be used as raw materials for cigarettes. At present, the curing and modulation of flue-cured tobacco leaves are all carried out in the curing room. The high-temperature circulating air after heat exchange with the heat source is used to dehydrate and heat the tobacco leaves in the curing room, so that the chemical components in the tobacco leaves react and become more coordinated. . With the development of air energy heat pump technology, and the tobacco leaf baking season is concentrated in July-October when there is plenty of light and high outdoor temperature, the technology of using air energy heat pump for curing barns is constantly being developed, and the exist...

Problems solved by technology

However, there are still some problems in the air-energy heat pump barn in the prior art. For example, the air source heat pump cannot make full use of light energy, and the existing barn only leads it to the evaporator of the air source heat pump when dehumidifying. However, i
