Self-feeding type energy-saving grain drying device

Abstract

The invention discloses a self-feeding type energy-saving grain drying device comprising a base. A drying barrel is fixed to the top of the base through a support, a rotating tube is arranged in the center in the drying barrel, and the upper end and the lower end of the rotating tube are rotationally connected with the top wall and the bottom wall of the drying barrel correspondingly. A second speed reducing motor is fixedly arranged at the center of the top of the drying barrel, a motor shaft at the bottom end of the second speed reducing motor is fixedly connected with the top end of the rotating tube, and spiral blades are fixedly mounted at the tube section, located above a screen plate, of the rotating tube. A plurality of one-way air outlet holes are uniformly formed in the tube section, between the spiral blades, of the rotating tube. A hot air blower is fixedly arranged at the right part of the side wall of the drying barrel, the air inlet end and the air outlet end of the hotair blower are connected with hot air tubes correspondingly, and the air outlet end of each hot air tube is connected into the rotating tube. The hot air blower is used for introducing hot air into the rotating tube, the hot air is discharged from the one-way air outlet holes to dry grains, and the heat is uniformly distributed; and the spiral blades are driven by the rotating tube to rotate to drive the grains to roll, so that the grains are heated more uniformly when dried, and the drying effect is good.

Description

technical field [0001] The invention relates to the technical field of grain processing machinery, in particular to a self-loading energy-saving grain drying device. Background technique [0002] Grains cover a wide range, including rice, wheat, millet, soybeans, etc., and other miscellaneous grains, mainly plant seeds and fruits, which are the traditional staple food of many Asian peoples. After the grain is processed into grain pellets, it is generally necessary to dry the grain before storing it to avoid mildew caused by moisture in the grain. After a period of storage, it needs to be re-dried to prevent moisture regain. [0003] When the ordinary dryer is drying the grain, the heat is discharged together with the moisture, resulting in low heat energy utilization rate and low drying efficiency; and the grain generally contains dust, fine sand and other impurities, and the drying process of the ordinary dryer Impurities cannot be removed in the dryer, and the grain quali...

Problems solved by technology

[0003] When the ordinary dryer is drying the grain, the heat is discharged together with the moisture, resulting in low heat energy utilization rate and low drying efficiency; and the grain generally contains dust, fine sand and other impurities, and the drying process of the ordinary dryer Impurities cannot be removed in the dryer, and the grain quality is not high; since the feed inlet of the dryer is generally high, it is often necessary to manually climb up to feed, which is not only troublesome but also dangerous
