ABSTRACT:
A method for separating/classifying closed bolls of a given variety of cotton by maturity is disclosed. Harvested, unopened cotton bolls are immersed in a series of solutions having a specific gravity of less than one. The bolls of cotton are thus identified and separated by means of the different specific gravity readings. The specific gravity readings are correlated with the moisture content of the bolls and subsequently the maturity dates of the cotton. Additional steps for cleaning, washing and drying are provided as needed. Alcohol/water solutions are utilized to prepare solutions with specific gravities of 0.8379 to 0.9455.
