After some in-depth understanding, they generally believe that the corn drying warehouse is the most economical and practical storage method for directly harvesting corn kernels with machinery. There is no need to worry about the problem that corn kernels can not be stored and stored without drying.
Direct corn threshing harvest, referred to as corn grain direct harvesting, is the development trend of mechanized harvesting of corn in China, and is increasingly favored by agricultural machinery operators. In the agricultural machinery market that continued to slump in 2018, the corn kernel harvester accounted for a significant increase, and it is one of the few bright spot products. Take Jiutai District of Changchun City as an example. In 2018, there were more than 200 new corn harvesters in the region, and the number of users purchasing corn grain machines increased significantly, achieving zero breakthrough.
Corn drying warehouse However, due to the high moisture content of corn during harvest, corn grain must be directly sold to grain processing enterprises after direct harvesting, or immediately treated with a dryer. Otherwise, ordinary granaries cannot be stored and are prone to mildew. The direct sale of grain after harvest involves the market price at that time, and the dryer often cannot guarantee normal operation due to environmental problems, which will affect the development of corn grain direct harvesting operations.
Under this circumstance, corn-dried granaries came into being, and farmers can store them at home, thus promoting and driving the development of corn grain harvesting.
The corn drying warehouse is a post-harvest processing device for agricultural grain, and is a new three-dimensional drying facility for drying and storing corn by natural air drying. The air-drying warehouse is made of special materials and is welded and welded. It is usually made of hot dip wire. This hot dip wire is specially treated and then cold drawn, which has a strong anti-corrosion ability.
The corn air drying warehouse is composed of a plurality of small-diameter net barrels placed vertically at intervals. During the loading process, the entered corn can be dispersed, thereby increasing the space utilization rate and avoiding contact with the surface water gas to achieve the purpose of rapid drying.
The structure of corn air drying warehouse is simple and easy to construct. It can be used for many years. It can be used to form mechanical circulation. It saves time and effort, and the natural drying and processing cost is low. The average 1t corn can save about 60 yuan of drying and drying food costs. Food and labor costs and coal-fired drying costs are high and environmentally unfriendly.
The main component of the row of air-drying warehouses is the drying box, which has a discharge hopper at the bottom. The drying box is composed of a frame and a plurality of dividing plates. The dividing plate is generally shaped like a pointed top, the surface of which is covered with mesh holes, the frame shape is a rectangular parallelepiped, the frame is surrounded by a protective net, and the dividing plates in the frame are arranged layer by layer. Generally, it is divided into long and short. The long board is generally arranged horizontally, while the short board is arranged vertically.
At present, there are many manufacturers in Hebei, Henan, Liaoning and other provinces (municipalities) producing corn drying warehouses, which have different sizes and specifications, mostly 4.6, 0.63, 3 or 3.2, 0.63, 4.5m (length, width, height), etc. A warehouse can store about 4 tons of corn kernels. Generally, 2.5 to 3 air drying bins per hectare of corn are required.
stainless steel screen mesh is woven with stainless steel wire such as 201, 202, 304, 304L, 316, 316L etc. the weaving type for screen mesh is determined according to our customer. Such as plain weave, plain dutch weave, twill weave, dutch twilled weave, and also for material, wire diameter, mesh size, width can also be customized. The Stainless Steel Woven Mesh is anti-corrosion, wear-resistance, heat-resistance, and acid-resisting, based on this characteristics, the stainless steel woven mesh is extensively used in mining, chemical industry, food industry and pharmaceutical industry.
Stainless steel screen mesh material:
304, 316, 304L, 316L, 430, 310s etc.
Wire diamter: 0.025mm to 18mm
Weaving method: plain weave, plain dutch weave, twill weave, dutch twilled weave
1. Plain Weave: also called tabby weave, linen weav or taffeta weave, is the most basic type of weaves. In plain weave, the warp and weft are aligned so they form a simple criss-cross pattern. Each weft thread crosses the warp threads by going over one, then under the next, and so on. The next weft thread goes under the warp threads that its neighbor went over, and vice versa.
2. Twill Weave: In a twill weave, each weft or filling yarn floats across the warp yarns in a progression of interlaces to the right or left, forming a distinct diagonal line. This diagonal line is also known as a wale. A float is the portion of a yarn that crosses over two or more yarns from the opposite direction.
3. Plain Dutch Weave: similar with plain weave, just the weft and warp wire have different wire diameter and different mesh size.
4. Twill Dutch Weave: similar with twill weave, just the weft and warp wire have different wire diameter and different mesh size.
5. Reversed Dutch Weave: difference from standard Dutch weave lies in the thicker warp wires and less weft wires.
