Delinting Machine DLT10-2

DLT10-2 delinting machine is normally used in acid delinting method for most of research institutes. Cottonseed, as the by-product of cotton ginning operation, is covered with fibrous lint. The cottonseed is enclosed in the fibrous hull. Over the hull stick out the cotton fiber which escapes the ginning and left on seeds. These cotton fibers are called “lint”.

Two general methods have been developed for removing the lint from cottonseed, which is removing the lint by acid and by delinter machine respectively.

The acid delinting of cottonseed has been used extensively, particularly when the seeds are used for planting. Both sulfuric acid and hydrochloric acid have been used for acid delinting respectively. Due to the generation of heat from the reaction of the acid with the moisture, the short cotton fibers on the seed would quickly disintegrate. The residue can be washed away with water. After washing, the seed needs to be neutralized with soda ash, lime, or anhydrous ammonia, which is regarded as the wet acid method.
