Energy saving and environment protecting circulating type grain drying device

Abstract

The invention discloses an energy saving and environment protecting circulating type grain drying device. The grain drying device comprises a first barrel body and a second barrel body which are arranged in parallel, wherein the length of the first barrel body is larger than the length of the second barrel body, and the transverse central lines of the first barrel body and the second barrel body are arranged in a coincided manner; a first rotating shaft is arranged in the first barrel body, and a first helical blade is fixedly arranged at the periphery of the shaft body of the first rotating shaft; a second rotating shaft is arranged in the second barrel body, a second helical blade is fixedly arranged at the periphery of the shaft body of the second rotating shaft, and the turning direction of the second helical blade is opposite with that of the first helical blade; both the first rotating shaft and the second rotating shaft are of hollow structures, and electric heating wires are arranged in the first rotating shaft and the second rotating shaft; and a fan is arranged in the central position below the first barrel body and the second barrel body. Grains are dried by adopting a circulating manner, so that the grains are uniformly heated, and the drying effect is improved. At the same time, the heat utilizing rate is high, and the device has better energy saving and environment protecting effects.

Description

technical field [0001] The invention relates to a drying device, in particular to an energy-saving and environment-friendly circulating grain drying device. Background technique [0002] Five grains mainly include rice, wheat, soybeans, etc. and other miscellaneous grains, such as millet, black rice, buckwheat, oats, barley, sorghum, etc. Through processing, grains provide humans with 50% to 80% of heat energy, 40% to 70% of protein, and more than 60% of vitamin B1 for humans. Cereals can vary greatly in their nutrient content due to different types, varieties, origins, growth conditions and processing methods. [0003] Grains are stored for a long time after harvesting, so they need to be dried to reduce the moisture content. Most of the grains in the existing grain drying device are in a static state during the working process, which may easily lead to uneven heating, thus affecting the drying effect. , At the same time, the utilization rate of heat energy is low, which ...
