Cotton seed delinting process method and drying device special for method

Abstract

The invention discloses a cotton seed delinting process method and a drying device special for the method. The process method mainly comprises the processes of acid liquid preparation, quantitative acid application, drying and frictional delinting. The process method is characterized in that the drying is performed in the following special device that: the device comprises a drying roller (6) and a drying roller transmission mechanism (15); the end of the drying roller (6) is provided with at least one feeding hole, and a seal cover is arranged on the feeding hole; and the lower part of the drying roller (6) is provided with a heating device (13), and meanwhile, the drying roller (6) is also provided with a turnover lifting device (12) capable of turning over the drying roller (6) towards the direction of the feeding hole. Compared with the prior art, the drying roller is heated outside an acid stirring drying roller, and acid-spraying stirring can be performed on the cotton seeds in the drying roller when the drying roller is heated, so the drying operation time is shortened, the relative volume of the drying roller can be small, the cost of a drying device is reduced, and the drying device has low energy consumption and dries the cotton seeds uniformly.

Description

technical field [0001] The invention relates to a cotton seed delinting process method and special drying equipment for the method. Background technique [0002] Cotton is a strategic material related to the national economy and people's livelihood, and it is also an important economic crop, which has an important impact on the development of the national economy. [0003] The processing of cotton seeds is an important link in cotton production, and the delinting of cotton seeds is a particularly critical process in cotton seed processing. [0004] At present, cotton seed delinting technology at home and abroad is mainly divided into mechanical delinting and chemical delinting. Because mechanical delinting is easy to break the seeds seriously, except for special purposes, it is generally not used much, so at present, chemical methods are mainly used for delinting, such as the currently popular sulfuric acid method. Sulfuric acid delinting is divided into two types, one is ...

AI Technical Summary

Problems solved by technology

The disadvantages of this process are: complex process, high equipment cost; excessive soaking of cotton seeds in acid solution for a long time, acid solution may penetrate into the inside of cotton seeds through the cracks of cotton seeds, affecting and reducing the vitality and germination rate of cotton seeds. This method should not be used for varieties with thin seed coats

[0007] Both of the above two processes adopt the air convection heating method. When heating, the hot air is input into the cotton seed drying drum through the pipeline, and then the excess hot air is drawn out by the exhaust fan on the other side. The hot air flows too fast, the heat utilization is low, and the energy consumption is low. high

At the same time, because the hot air in the drum heats the cotton seeds through convection, the heating effect is poor, and the cotton seeds are not easy to dry evenly. Generally, it takes a long time to achieve the expected effect. The drying time is long. The length of the drying drum is solved, so the equipment volume is too large, the length of the dryer is often more than 10 meters, and the cost is also high
