Energy-saving and environment-friendly drying room

Abstract

The invention belongs to the technical field of drying of food, crops and traditional Chinese medicinal materials, and particularly relates to an energy-saving and environment-friendly drying room. The energy-saving and environment-friendly drying room comprises drying chambers and a heating chamber, wherein the drying chambers are located on the two sides of the heating chamber, and the heating chamber communicates with the drying chambers; and circulating fans are arranged on the side, away from the heating chamber, of each drying chamber, the front faces of the circulating fans face the heating chamber, and the back faces of the circulating fans communicate with the heating chamber through a circulating channel in the top of the drying chamber. Due to the design that a heating device is centered in the drying room, heat can be provided in an air heat conduction mode and a heat radiation mode at the same time, heat in the drying room is evenly dispersed, the drying time is kept consistent, the drying time of each batch is shortened, and the drying efficiency is improved. Meanwhile, natural gas and petroleum gas are used for replacing coal, so that energy conservation and environmental protection are achieved, the utilization rate of heat energy is increased, the fuel cost and carbon emission are reduced, energy consumption and labor are saved, and meanwhile the problem that the drying room pollutes the surrounding environment is solved.

Description

technical field [0001] The invention belongs to the technical field of drying food, crops and Chinese medicinal materials, and in particular relates to an energy-saving and environment-friendly drying room. Background technique [0002] On September 22, 2020, the Chinese government proposed at the 75th session of the United Nations General Assembly: "China will increase its nationally determined contribution and adopt more powerful policies and measures. achieve carbon neutrality years ago." [0003] Our city also regards energy conservation and emission reduction as an important assessment standard in all aspects of agriculture, food, and Chinese herbal medicine production. [0004] 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 ...

AI Technical Summary

Problems solved by technology

[0005] The existing drying room has the problems of uneven heating, heat cannot be circulated and convected, large heat loss, and low working efficiency

Moreover, the flue gas discharged from the combustion furnace used to provide heat for 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 the most concerned links after the energy shortage and environmental problems have been paid attention to, but they have not yet been perfectly solved in the field of drying room technology.
