Abstract
Apparatus and method for delinting cottonseed wherein a moving body of cottonseed is subjected to a flame treatment for burning off excess linters, then subjected to an acid treatment wherein foamed sulfuric acid of adequate water content is deposited on the seed and the seed agitated, and then the seed is dried and the acid degraded linters removed. In an important embodiment the seed is acid treated, dried and buffed to remove degraded linters serially in at least two successive stages.
Claims10
Apparatus for the delinting of cottonseed comprising means for providing a continually moving mass of cottonseed to be delinted, controlled means for generating foamed sulfuric acid in operative concentration and depositing said foamed sulfuric acid in said mass of seed while agitating the seed for distributing the foam throughout the seed mass comprising means for continually supplying and admixing proportionate quantities of sulfuric acid and a foaming agent to form a mixture, a foaming device into which said mixture is introduced and converted into foam, and means for conveying the foam to discharge opening means along the moving cottonseed mass, said foaming agent being supplied in sufficient amount to convert substantially all of the mixture to foam, and said acid being present in the foam in sufficient amount for complete degradation of the linters and containing sufficient water to ensure complete wetting and saturation of the linters, and means for passing the seed through an operatively associated dryer-buffer system for lint removal.
