Straight bar infrared corn cob dryer

Abstract

The invention provides a straight-rod type infrared corncob drying machine. The straight-rod type infrared corncob drying machine is characterized in that a plurality of conveying devices driven by a transmission device to run are arranged in a box; a plurality of shifting rods are fixed on bent plates, correspondingly stretching towards the inner side, of two chains of the same conveying device by two connectors on the ends; each conveying device is provided with supporting grooves corresponding to spaces below the upper horizontal section and the lower horizontal section of each chain, respectively; a guide groove is formed below the tail end of each supporting groove; a radiation device for radiating an infrared ray unidirectionally downwards is arranged above each support groove; a charge opening is formed in the top of the box, and a discharge hole is formed in the bottom of the box. The straight-rod type infrared corncob drying machine provided by the invention is high in heat transfer efficiency, low in energy consumption, good in drying uniformity, simple and reasonable in structure, and high in working reliability.

Description

technical field [0001] The invention provides a straight-rod infrared corn ear dryer, which is mainly used for dehydrating and drying wet corn ears with high moisture content just after picking from corn stalks. Background technique [0002] China is a large agricultural country, especially in Shandong, Henan and Northeast China, which are the major food producing areas such as corn. With the development of the breeding industry and the increase in the demand for feed, the planting area of ​​corn has gradually expanded, and the output has increased year by year. The harvest moisture of corn is generally 25%~35%. If there is no good corn drying equipment, it will cause a lot of loss due to excessive moisture and mold. Therefore, farmers' demand for corn dryers is becoming more and more urgent. It is of great significance to develop corn dryers with high precipitation, good drying uniformity and high quality to promote the development of corn industry. [0003] At present, t...

AI Technical Summary

Problems solved by technology

The corn cob dryers involved in the above patents all adopt hot air convection drying, which consumes relatively high energy consumption and sometimes causes corn kernels to burst. After changing to infrared radiation drying, a national invention patent was applied for, and the patent number is: ZL201310056847.7 ; After changing to a rotatable shifting rod to make the feeding trough convenient to support, a national invention patent was applied for, the application number is: 201310060839.X; after the limit sleeve was added, a national invention patent was applied again, the patent number is : ZL201310065945.7; After adding the toggle wheel or toggle mechanism, it applied for a national invention patent, and the application numbers are: 201410060366.8 and 201410110342.9

However, the infrared corn ear dryer involved in the above-mentioned patent has a complicated structure and poor working reliability.
