An energy-saving and environment-friendly drying room for drying Chinese medicinal materials or grains

Abstract

The invention belongs to the technical field of crop and Chinese herbal medicine drying, and particularly relates to an energy-saving and environment-friendly drying room for drying Chinese herbal medicine or cereals. The drying room comprises an upper-layer compartment and a lower-layer compartment, wherein the upper-layer compartment and the lower-layer compartment are formed by dividing the drying room through a horizontal division plate, and a certain distance is maintained between the two ends of the horizontal division plate and the side walls of the drying room. The drying room further comprises circulating fans and smoke filtering equipment, and a heating device and the circulating fans are arranged between the side walls of the drying room and the horizontal division plate; the heating device comprises a combustion furnace and a tubular heat exchange device communicating with the combustion furnace, and an outlet end of the tubular heat exchange device communicates with the smoke filtering equipment arranged outside the drying room through a pipeline; the pipeline communicating with the tubular heat exchange device and the smoke filtering equipment is connected to an exhaust fan. The drying room is high in drying efficiency, increases the utilization rate of the heat energy and lowers the energy consumption, and smoke formed by fuel combustion is filtered by the smoke filtering equipment for removing dust so that the problem of pollution of the drying room to the surrounding environment can be solved.

Description

technical field [0001] The invention belongs to the technical field of drying crops and Chinese medicinal materials, and in particular relates to an energy-saving and environment-friendly drying room for drying Chinese medicinal materials or grains. Background technique [0002] At present, the existing crops are dried either by manually exposing the crops in the sun, or drying them in a drying room. For the former, due to the direct radiation of heat energy to the crops, the crops are not evenly heated, the dust pollution is large, and the dehydration time of the crops is longer. For large-scale drying needs, or in southern China with more rainy weather, drying rooms are mainly used. The drying room is widely used in various fields, including agricultural products, chemical products, Chinese medicinal materials, etc. It has the advantages of less energy consumption, less environmental pollution, and a wide range of applications. The drying principle is: the hot air is sen...

AI Technical Summary

Problems solved by technology

[0003] In the existing drying room, there are problems that the crops are not heated uniformly, the heat cannot be circulated and convected, the heat loss is large, and the working efficiency is low.

Moreover, the combustion furnace used to provide heat to the drying room takes away a large amount of heat and discharges harmful smoke and dust, which cannot meet the needs of energy saving and environmental protection.

However, energy saving and environmental protection are just the most concerned links after energy shortage and environmental problems have been paid attention to, but at present, they have not been perfectly solved in the field of drying room technology
