Pretreatment process for seed cotton

Abstract

The invention discloses a pretreatment process for seed cotton, which comprises the following steps of: separating heavy impurities; separating foreign fibers from the seed cotton; drying: drying second characteristic seed cotton; primarily separating small impurities: separating the small impurities and third characteristic seed cotton from the dried second characteristic seed cotton; separating cotton boll shells and part of cotton stalks: separating the cotton boll shells, the part of cotton stalks and fourth characteristic seed cotton from the third characteristic seed cotton; drying: drying the fourth characteristic seed cotton; separating small impurities: separating the small impurities and fifth characteristic seed cotton from the fourth characteristic seed cotton; and gathering up the fifth characteristic seed cotton for storing or directly conveying to processing equipment. Through the pretreatment process for the seed cotton, the impurities and dampness can be effectively removed from the seed cotton so as to prolong the processing cycle of the seed cotton picked by a cotton picker.

Description

technical field [0001] The invention relates to a seed cotton pretreatment process, in particular to a process for pretreating mechanically picked seed cotton. Background technique [0002] my country is a big cotton producing country in the world, but at present most of the cotton is picked manually, the picking process takes a long period and wastes a lot of manpower and material resources. With the development of technology, the proportion of mechanical picking is increasing. It is necessary to vigorously promote mechanical picking in a large cotton-producing country like ours. However, machine-picked seed cotton has its inherent defects, that is, the moisture regain rate is high, and the impurity content is generally greater than 25%. Due to the combined effect of moisture regain and impurities, it is easy to cause rot or spontaneous combustion accidents when stored for a long time, resulting in Big loss. Due to the difficult storage characteristics of machine-picked s...

Problems solved by technology

[0003] The existing domestic pretreatment of organically picked seed cotton is carried out on the ginning production line at the same time. It is difficult to obtain the same quality as hand-picked cotton by simply removing impurities from the machine-picked seed cotton. The disadvantage of this process is that when the entire production line When there is a failure from the ginning part to the baler part, the machine-picked seed cotton seed cotton processing equipment will also stop production; second, when processing hand-picked cotton, the machine-picked seed cotton pretreatment processing equipment can only be shut down and cannot be used

This greatly delays the processing cycle of machine-picked seed cotton, and machine-picked seed cotton has the above-mentioned defects of poor general condition, difficult storage, and short processing cycle, which may cause a large amount of natural loss due to a slightly longer storage time.
