Description

Grain crop particle screening equipment for agricultural production

Technical Field

The invention relates to the technical field of grain crop processing, in particular to grain crop particle screening equipment for agricultural production.

Background

Grain crops are a collective term for cereal crops (including rice, wheat, barley, oats, corn, millet, sorghum, etc.), tuber crops (including sweet potato, tapioca, etc.), legume crops (including soybean, broad bean, pea, mung bean, small bean, etc.). It can also be called as edible crop. The product contains starch, protein, fat, vitamins, etc. The cultivated grain crops not only provide food and certain auxiliary foods for human beings to maintain the life requirement, but also provide raw materials for the food industry and provide concentrated feed and most of coarse feed for the animal husbandry, so the grain production is the basis of agriculture in most countries. Typically, grain crops are also the dominant crop in crops, with world grain crop planting area accounting for about 85% of the total crop planting area, where wheat, rice and corn account for about 80% of the total world grain yield. China is the largest grain-producing country in the world, grain crops account for 76.8% of the total sowing area of crops (1987), and the total yield of grains and the yields of rice, wheat, millet and sweet potato all stay in the front of the world.

Corn is used as a feed, food and industrial feedstock, and in latin america, corn is widely used as a tortilla that is not fermented. Corn is eaten in all regions of the united states, and is made into various foods such as boiled (or roasted) corn cobs, cream corn flakes, corn grits (corn grits are made in the south), corn puddings, corn paste, corn porridge, scones, corn tortillas, popcorn, cakes and the like.

Wheat is the second grain crop in total world yield, next to corn, and rice is the third. The caryopsis of wheat is one of the staple foods of human beings, and can be made into foods such as bread, steamed bread, biscuits, cakes, noodles and the like after being ground into flour; after fermentation, beer, alcohol, vodka, or biomass fuel can be produced. Wheat is rich in starch, protein, fat, minerals, calcium, iron, etc.

Sorghum can be classified into edible sorghum, sugar sorghum, broom sorghum and the like according to properties and purposes. The cultivation in China is wider, and the northeast places are the most. The grains can be used for eating, brewing wine (Kaoliang spirit) or making maltose. Sugar sorghum stalks can be used for preparing syrup or raw food; broom broomcorn ears can be used for making broom or broom; the tender leaves are dried in shade and ensiled, or can be used as feed after being dried in the sun; ying Guo can be used as a medicine, and can dry dampness, eliminate phlegm, calm heart and tranquilize mind.

Soybean is one of Chinese important grain crops, and is a crop whose seed contains rich plant proteins. Soybeans are most commonly used for making various bean products, extracting soybean oil, brewing soy sauce, and extracting proteins. Okara or ground soybean is also commonly used in livestock feed.

After a series of pretreatment, the granular grain crops are usually required to be screened for one time to remove the particles which are shrunken and have smaller volume, so that the whole particles are more uniform, and the whole quality is improved; the existing screening mode is generally that a large amount of grain particles are directly put into screening equipment, the input amount of materials is large during each screening, the screening difficulty is increased, the screened materials cannot be collected in time, and the use is inconvenient.
