Technical Field

The invention relates to the technical field of cotton seed treatment, in particular to an indicating label for cottonseed acid delinting.

Background

Cotton is one of the important economic crops in China, the processing of cotton seeds is an important link in the cotton planting industry, and the cotton seeds provide important guarantee for the yield and the quality of the cotton along with the development of national economy and the cotton industry in China; generally, harvested seed cotton is subjected to a cotton binding process, cotton linters and cotton seeds are separated to form wool cotton seeds, the bound wool cotton seeds are generally provided with 6-7mm short fibers which are not suitable for being directly used as seeds, germs carried in the short fibers can influence the germination rate of the cotton seeds and increase the seedling morbidity, and the residual short fibers on the wool cotton seeds are generally removed through delinting treatment.

The cotton seed delinting method in the cotton seed processing machine mainly comprises chemical cotton seed delinting and mechanical cotton seed delinting, wherein the chemical cotton seed delinting mainly comprises the step of carbonizing and embrittling residual cotton on the surface of cotton seeds by strong acid to cause the residual cotton seeds to fall off. The common delinting method is to carry out wetting treatment on the lint on the surface of the cottonseed by using sulfuric acid, namely, carrying out acid seed reaction, and carrying out centrifugal drying or drying treatment after the reaction is finished, so that the acid-etched and carbonized short lint on the surface of the cottonseed is removed by friction, and the cottonseed which can be used as a seed is obtained. However, in the cotton ginning process, the thickness of the wool layer on the surface of the wool cotton seed is different, so that acid liquor consumed in the acid seed reaction is difficult to control; the problem that the germination rate of the seeds is reduced because the cotton lint can not be removed or the residual acid of the bare seeds is too high is caused. Therefore, it is necessary to control the delinting time of the wool cotton seeds to ensure the delinting quality of the cotton seeds and control the acid seed reaction time to reduce the damage of excessive reaction to the seeds.
