Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of agricultural product drying and storage, and particularly relates to an integrated drying and storage bin. BACKGROUND

[0002] Grains, oilseeds and other agricultural products have a high moisture content when harvested, and need to be dried in time to prevent mildewing and deterioration. According to statistics, the mechanization rate of post-harvest quality protection links such as drying and storage of grains in China is only 38%, and the mechanization rate of post-harvest quality protection links of oilseeds is about 26.7%, which cannot meet the demand for mechanized drying and storage of grains and oilseeds. At present, the post-harvest comprehensive loss rate of grains and oilseeds in China is 15.28% and 14.97% respectively, among which, the loss rate of drying and storage links of grain storage by farmers is 5.2% and 10.09% respectively, and the loss rate of drying and storage links of oilseed storage by farmers is 6.21% and 20.04% respectively. The loss rate in the whole link from post-harvest to sale is the highest, which affects the effective supply of grains and oilseeds and the increase of farmers' income. In recent years, mechanized drying has been developed vigorously, but still faces problems such as great difficulty in approval of construction land, large investment cost, high operation cost and low profit rate. Mechanical ventilation is a green drying and storage technology recognized by the world, which can reduce drying energy consumption, integrate drying and storage functions, reduce the area of construction land, improve equipment utilization rate, and maintain appropriate moisture content to meet the subsequent processing demand. In addition, the business entity can temporarily store grains and oilseeds and sell them at the right time to improve the comprehensive benefits of grain production.

The cylindrical drying bin device has a conical upper cover and an inverted conical lower cover. The invention can realize electric heating grain drying and avoid the environmental pollution problem caused by traditional coal drying. However, there are problems such as complex ventilation pipe structure, existing structure prone to material discharge stagnation, and lack of effective heat insulation measures for the bin body. The prior art of a grain production and storage integrated bin and operation method has the application number 202311293005, and the structure comprises a cylindrical bin, a ventilation system and a material uniformizing system, which greatly improves the uniformity of grain ventilation drying.

[0067] Step 3: Detect and determine the moisture content of the material fed into the silo body;
