Efficient environment-friendly grain drying machine

Abstract

The invention relates to the technical field of grain drying, and discloses an efficient environment-friendly grain drying machine. The efficient environment-friendly grain drying machine comprises adouble-channel drying part, a storage part, a discharging part and a feeding and discharging system. The double-channel drying part is used for drying grains, and comprises to drying boxes arranged inbilateral symmetry, an air heating chamber communicating with the two drying boxes is arranged between the two drying boxes, and the air heating chamber is externally connected with a drying medium through an air inlet box. A waste gas chamber communicating with the drying box is arranged on the side, away from the air heating chamber, of each drying box, and each waste gas chamber is connected with an exhaust fan through an air outlet box. A mixed-flow structure is adopted by the double-channel drying part, air input is achieved in the middle, air output is achieved on the two sides, heat loss can be reduced to the maximum extent, and the drying and energy saving effects are obvious; variable-section air input angular boxes and air outlet angular boxes are arranged in a staggered manner,so that the grains flow downwards in the drying boxes in an S shape, and thus the grains and drying hot are in full contact, heating is more uniform, and compared with an existing drying machine, thedrying efficiency and the quality of the dried grains are obviously improved.

Description

technical field [0001] The invention relates to the technical field of grain drying, in particular to an efficient and environment-friendly grain drying machine. Background technique [0002] In recent years, my country's grain mechanized drying has been rapidly developed and applied. Grain dryers have been widely used in grain storage, processing, distribution enterprises, cooperatives and large grain growers. This effectively solves the problem of grain storage. The loss caused by mildew caused by too late to dry. The existing grain drying equipment in my country is mainly hot air drying, and there are two types of high-temperature continuous type and low-temperature circulation type. The existing grain drying equipment and drying mode are conducive to promoting the entire mechanization of agriculture in my country and reducing post-production Losses play a key role in ensuring national food security. [0003] With the continuous expansion of the grain drying market and th...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the problems of low drying efficiency and high energy consumption in the above-mentioned existing grain dryers, a high-efficiency and environment-friendly grain dryer that can solve or partially solve the above-mentioned technical problems is provided. After drying, it flows downward in an S shape, and the drying medium (hot air) in the oven is also in the form of S-shaped cross-flow two-way ventilation, so that the grain and the drying medium (hot air) can fully contact, ensuring the uniformity of grain drying. Thereby improving drying efficiency and reducing energy consumption
