Grain cleaning and destoneing equipment process

Whether it is grain processing or flour processing, grain will be cleaned up during processing, and there is no ability and energy to carry out grain fine cleaning in harvesting food, which requires grain processing enterprises to carry out initial cleaning and removal of impurity and stone removal of grain. So how does the grain cleaning machine equipment realize the process of removing impurities and removing stones?

Grain clear grain machine equipment first starts from grain impurities, food impurities are divided into organic impurities and inorganic impurities according to their composition, large and small impurities according to particle size, and light impurities and heavy impurities according to weight. The surface dust mentioned by the subject belongs to small miscellaneous, light immortal, inorganic impurities, straw belongs to large miscellaneous, light impurities, organic impurities, wheat bran belongs to small miscellaneous, light impurities, organic impurities. Large and small miscellaneous are usually removed by screening equipment, and the principle is to control the sorting by the particle size of the particles, and the sorting accuracy is high. Simply put, it is to separate materials of different particle sizes by the size of the sieve hole. Materials larger than the sieve hole remain on the sieve, and materials smaller than the sieve hole remain under the sieve, thus separating the materials of different particle sizes. Refined food impurity screening machine can be used, which is mainly used for screening and separation of large, medium and small and light impurities in grain, and is widely used in the initial invitation of wheat, feed, chemical industry and other industry magazine separation. The machine has simple structure, stable operation, low noise, low energy consumption and good cleaning effect.

Light and heavy impurities are usually removed by using winnowing equipment, and winnowing is a method of removing impurities by wind power by using the difference in suspension speed between materials and impurities. The purpose of winnowing is to remove light impurities and dust, while also removing some heavier impurities such as stones and clods. There are also special cleaning equipment, such as stone destoners, which are specially designed to remove stones in grain that are about the same size as grain, because of the grain size of this part of the grain.

For surface dust, straw, wheat bran, it is definitely necessary to choose a screening equipment, first remove large impurities such as straw through the screening equipment, and then select the winnowing equipment to remove dust and wheat bran. If the surface of the grain needs to be cleaned, add a striking device in the middle. Note that before hitting the equipment, a magnetic separation needs to be added to remove metal impurities to ensure the quality of food.
