Grain drying machine

Abstract

The invention discloses a grain drying machine. The grain drying machine comprises an outer barrel, a drying barrel and a filtering tank, wherein a rotating motor is fixedly installed on the side wallof the left end inside the outer barrel, the output end of the rotating motor is fixedly connected with the left end of a rotating shaft, and the right end of the rotating shaft is fixedly installedon the side wall of the right end inside the outer barrel through a bearing; and the drying barrel is fixedly installed on the circumferential shaft body of the rotating shaft through connecting rods,and a barrel body of the drying barrel is of a net-shaped structure. The upper end and the lower end of the outer barrel are fixedly connected with the left end of an air inlet pipe and the left endof a vent pipe respectively, the right end of the vent pipe is fixedly connected with the air inlet end of the filtering tank, and supporting plates are fixedly installed at the upper end inside the filtering tank; and a vibrating rack is fixedly installed on the supporting plates, a vibrating motor is fixedly installed on the vibrating rack, and an eccentric block is fixedly installed on an output shaft of the vibrating motor. The grain drying machine has the advantages of being high in cleanliness, easy to clean and the like and can be universally applied and popularized.

Description

technical field [0001] The invention belongs to the technical field of agricultural food preservation and processing, and in particular relates to a grain dryer. Background technique [0002] Food is a living organism, and water is the condition for its survival. However, if the water is too high, it will induce the growth of insects and microorganisms, which will easily cause food heating, fermentation, deterioration and a decrease in germination rate. At present, the control of grain moisture mainly includes natural drying and drying by grain dryers. Natural drying is easily restricted by the influence of weather and venues. In the main grain producing areas, due to the large output and insufficient drying space, the moisture in the grain purchased by the grain depot often exceeds the safe moisture. This is the main factor leading to grain mildew, especially in The grain purchase period is catching up with continuous cloudy days, and this is even more so. In addition, ev...

Problems solved by technology

[0003] However, most of the existing grain dryers are large and super large, and are fixedly installed in the grain processing plant. The equipment has high energy consumption, low automation level, and large investment. Farmers must transport the grain to the grain processing plant to dry the grain. Drying is not only troublesome, but also increases the cost
