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

The grain crops are the general names of cereal crops (including rice, wheat, barley, oat, corn, millet, sorghum and the like), potato crops (including sweet potato, cassava and the like), and bean crops (including soybean, broad bean, pea, mung bean, small bean and the like). Also called food crops. The product contains starch, protein, fat, vitamins, etc. The cultivation of grain crops not only provides food and some non-staple food for human beings to maintain the needs of life, but also provides raw materials for food industry and provides concentrated feed and most coarse feed for animal husbandry, so that the grain production is the basis of agriculture of most countries. Generally, grain crops are also the leading crops in crops, and the planting area of the world grain crops accounts for about 85% of the total sowing area of the crops, wherein wheat, rice and corn account for about 80% of the total yield of the world grain crops. China is the largest world-wide grain producing country, grain crops account for 76.8% of the total seeding area of crops (1987), and the total grain yield and the yields of rice, wheat, millet and sweet potatoes all live in the top of the world.

Corn is used as a feed, food and industrial raw material, and in latin america, corn is widely used as a non-fermented corn cake. Corn is eaten in every part of the United states and made into various foods such as boiled (or roasted) corn cobs, cream corn flakes, corn grits (made into corn coarse powder in the south), corn puddings, corn paste, corn porridge, scones, corn meat cakes, popcorn, cakes and the like.

Wheat is the second food crop of the world's total production, second only to maize, while rice ranks third. The caryopsis of wheat is one of staple food of human beings, and can be used for making bread, steamed bread, biscuits, cakes, noodles and other foods after being ground into flour; after fermentation, the product can be made into beer, alcohol, vodka, or biomass fuel. Wheat is rich in starch, protein, fat, minerals, calcium, iron, etc.

Sorghum can be classified into edible sorghum, sugar sorghum, broom sorghum, etc. according to its properties and uses. China has wide cultivation, and most of the cultivation is in the northeast. The grains are used for eating, brewing (sorghum liquor) or making maltose. The stalks of the sugar sorghum can be made into syrup or raw food; the broomcorn ears can be used as broomstick or cooking broomstick; drying young leaves in the shade, and ensiling, or sun drying to obtain feed; the caryopsis can be used as a medicine for eliminating dampness and phlegm, calming the heart and tranquilizing the mind.

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

After a series of pre-treatments are carried out on the granular grain crops, the granular grain crops are usually screened once to remove shriveled and small-sized grains so as to make the whole grains more uniform and improve the whole quality; the current screening mode is usually with a large amount of grain granule directly drop into screening installation, and the input of material is big when screening at every turn, increases the screening degree of difficulty, and can not in time collect the material that the screening got off, uses inconveniently.
