Negative pressure winnowing separation device for coix seed machining

Abstract

The invention belongs to the technical field of barley processing equipment, and in particular relates to a barley processing negative pressure winnowing and separating device, which includes a machine body, a feeding mechanism is arranged on the upper side of the machine body, a negative pressure winnowing chamber and a vibrating screening chamber are arranged inside the machine body, and The lower end of the press air separation chamber is connected with the upper end of the vibrating screening chamber. The two sides of the negative pressure air separation chamber are respectively provided with an air inlet and an air outlet. The outside of the air outlet is connected with a negative pressure fan, and the lower end of the negative pressure fan is connected with a dust collection mechanism. ; There is a first-level brushing mechanism and a second-level screening mechanism in the vibrating screening chamber. The primary screening mechanism is connected with the second discharge chute, and a vibrating mechanism is also provided in the vibrating screening cavity, and the vibrating mechanism is respectively connected with the primary brushing mechanism and the secondary screening mechanism. The advantage is that the method can not only improve the sorting effect, but also save the cost of barley processing.

Description

technical field [0001] The invention belongs to the technical field of barley processing equipment, and in particular relates to negative pressure air separation equipment for barley processing. Background technique [0002] The nutritional value of barley is very high, and it is known as "the king of grasses in the world". The seed of Job's tears can be used as grain to eat, and taste is similar to rice, and easy to digest and absorb, cook porridge, make soup all can. In summer and autumn, boil soup with wax gourd, which can be eaten as a meal, and can clear away summer heat and dampness. Because barley is rich in nutrients, it is a good medicinal food for patients with chronic illness and physical weakness, recovery period after illness, the elderly, puerpera, and children, and can be taken frequently. No matter it is used for nourishing or curing diseases, the effect is relatively mild, slightly cold but not hurting the stomach, benefiting the spleen but not greasy. Ac...

Problems solved by technology

[0003] At present, in the process of barley and rice processing, the separation method of rice and bran (hull) is separated by direct blowing in the wind cabinet; since barley is much larger than other grain particles, the shell of barley after peeling is relatively thick, and it will absorb On barley, the separation of rice and shells is not complete, which directly affects the quality of the product; in addition, the existing air separation equipment for barley only has a single air selection function, and the separation of part of the coarse shells and fine particles in the barley needs to be done in It is carried out in other equipment, which not only greatly limits the processing efficiency, but also increases the cost of barley processing
