Rotating rod type infrared corncob drier

Abstract

The invention provides a rotating rod type infrared corncob drier. The rotating rod type infrared corncob drier is characterized in that a plurality of conveying devices which are driven by a driving device to convey are arranged in a box body; one end of a bolt is screwed into a screw hole of a chain node on the inner side of a chain; the two ends of a material shifting rod are hollowly sleeved on the middle part of the bolt; a limit ring of which a deep concave hole contain steel balls keeps the steel balls to face the material shifting rod; the steel balls fall into a shallow concave hole of the material shifting rod and are loaded into the middle part of the bolt; each conveying device is respectively provided with material supporting plates corresponding to an upper horizontal section and a lower horizontal section of the chain; a material guide groove is formed below the tail ends of the material supporting plates; a radiating device which downwards radiates infrared ray in one direction is arranged above the material supporting plates; limit rods are arranged at the two ends of each conveying device, so that when the material shifting rod moves to a chain wheel to reverse, on one hand, the material shifting rod co-rotates along the chain wheel, on the other hand, the material shifting rod reversely rotates around the bolt at the speed equal to the co-rotation angular velocity; a material inlet is formed in the top of the box body; and a material outlet is formed in the bottom of the box body. The rotating rod type infrared corncob drier is high in heat transfer efficiency, good in drying uniformity, reasonable in structure, convenient to use and practical.

Description

technical field [0001] The invention provides a rotary-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, the...

Problems solved by technology

The corn cob dryers involved in the above patents all use hot air convection drying, which consumes relatively high energy consumption and sometimes causes the corn kernels to burst. After changing to infrared radiation drying, a national invention patent was applied for, and the application number is: 201310056847.7

However, the infrared corn ear dryer involved in this patent adopts a fixed connection between the ring-shaped material rod and the chain, and the conveying device adopts double-sided conveying technology, which makes it difficult to fix the supporting plate
