What is the cotton processing machinery?
Cotton processing machinery refers to the machinery and equipment that can remove all kinds of impurities in cotton, and compress, separate and bundle cotton fiber without damaging the natural quality of cotton fiber. Although cotton processing machinery has been widely used in agricultural production, but many people are not very familiar with its use method.
Cotton processing machinery mainly includes cotton dryer, cotton cleaner, gin, wool stripping machine, baler, cotton seed oil press, etc., as well as for cotton scraps recycling, material transportation, ventilation and dust removal, safety and fire prevention and other auxiliary equipment.
Technology and function of cotton processing machinery:
Cotton processing machinery can remove all kinds of impurities in cotton, and cotton fiber (lint and short wool) and cotton seed separation, compression, bundle without damaging the natural quality of cotton fiber machinery and equipment. It mainly includes cotton dryer, cotton cleaner, gin, wool er, baler, cotton oil press, etc., as well as auxiliary equipment for cotton foot recycling, material transportation, ventilation and dust removal, safety and fire prevention and so on. Since the 19th century, with the development of production technology, cotton processing has been developed from single machine production to a complete processing process and independent processing industry, so as to provide good processing textile raw material ── cotton for the textile industry.
Cotton dryer in cotton processing machinery is used to reduce the water content of seed cotton, so that it is kept in the range of 6~8% in the processing process, so as to improve the processing efficiency of cotton processing, improve the quality of lint and reduce energy consumption. In 1932, the United States developed a tower cotton dryer, which gradually replaced the drum dryer. The tower dryer is a multi-layer box structure, the cotton mixed with hot air from the upper entrance into the box, under the action of airflow and its own gravity, from the snake movement from top to bottom, baking 7 ~ by the lower exit for 10 seconds, part of the moisture of the cotton is taken away by the hot air.
Cotton cleaning machine in cotton processing machine is used for cleaning. There are brush type serrated roller, airflow type serrated roller and airflow type linons cleaning machine and other types, the first two are to use the serrated roller hook linons fiber, so that the separation from impurities, and then with the brush roller or airflow brush linon. The latter is the channel that enables the lint to enter the machine under the high speed air flow. At the corner of the channel due to the narrow section, the heavier debris in the lint ejected from the nozzle here, and the lint continues to be discharged through the outlet along the enlarged section after the turning.
The purpose of cotton seed processing:
to adopt a series of physical and chemical methods under the premise of not changing the original quality of good seed
Remove the short wool on the surface of cotton seeds, and then select and drug treatment, so as to improve the overall quality of seeds, improve their seeds nature. Make the excellent biological characteristics of the tree body come into full play.2 The dethread of cotton seed contains two meanings.
It is the appearance quality, that is, whether it is light seed after stripping. If there is short velvet exceeding the standard, it will affect the selection effect, seed coating agent treatment and machine
Arrogative sowing. The second refers to the internal quality of cotton seeds, that is, whether the process of develvet has adverse effects on the growth and development of seeds, seeds
Whether the water meets the safe storage standard, whether the amount of residual acid on the seed surface meets the requirements, the staple quality and the original water of the seed.
Seed rate, seed content, dilute sulfuric acid supply, hot air temperature and flow, drying time and maximum seed temperature and other factors Control related.
