Grain drying and storing granary

Abstract

The invention discloses a grain drying and storing granary which is characterized by comprising a grain storing case. A plurality of air pipes are arranged in the grain storing case, one end of each air pipe is connected with a ventilation pipeline, a plurality of ventilation holes are formed in each air pipe, the top of the grain storing case can be opened to be used as a grain inlet, a ventilation cavity is arranged at the bottom of the grain storing case, a sieve plate is arranged on the top surface of the ventilation cavity, air holes are formed in the ventilation cavity and respectively correspond to two ends of each air pipe, each air hole at one end of the corresponding air pipe is connected with the ventilation pipeline, the two ends of each air pipe and the air holes of the ventilation cavity can be opened and closed under the control of corresponding valves, and a grain outlet is arranged on the lower side of a side wall of the grain storing case. The grain drying and storing granary has the advantages that the grain drying and storing granary is simple and practical in structure, harvested high-moisture grains can be loaded into the grain drying and storing granary at one step, and grain piles can be stereoscopically bi-directionally dried at a low temperature in a multilayer manner, so that the safe storage requirement on the moisture content of the grains can be timely and quickly met, the high-moisture grains can be dried by the grain drying and storing granary, and the integrity of the grains can be guaranteed.

Description

technical field [0001] The invention relates to a drying grain storage bin. Background technique [0002] The "post-harvest loss" of my country's grain production is astonishing. According to data from the Ministry of Agriculture, due to poor facilities, primitive methods, and backward technology, the post-harvest loss rate of my country's grain is as high as 8% to 15%, which is much higher than the post-harvest loss rate of 3% in developed countries. According to rough statistics, even if calculated on the basis of 8% loss, the annual grain loss amounts to 70 billion catties. Therefore, inventing a kind of drying equipment and simple fresh-keeping storage method that is easy to popularize, economical and practical, suitable for my country's national conditions and can maintain the original quality of grain is of great significance. Important political significance and economic value. [0003] For the existing national grain reserve depots and local grain reserve depots, st...

Problems solved by technology

The effects of intelligent ventilation and cooling, precipitation, grain cooling and low-dose circulation fumigation are still not ideal, let alone timely processing of high-moisture and wet grains harvested in rural areas when harvesting in large quantities in rural areas
