Claims8
A combination dryer-cleaner apparatus for a cotton gin for enhancing the drying function and cleaning function of seed cotton while reducing damage to the fiber of said seed cotton, the apparatus comprising:
- a) a dryer for receiving raw field cotton, said dryer having a housing and at least one rotating cylinder for busting any compacted wads of field cotton and for dispersing the field cotton into individual bolls and thrusting them upon at least one inclined shelf to enhance drying, said dryer also having a circuitous route for transferring the cotton to a cleaner to enhance drying;
- b) a cleaner having a plurality of cylinders for dragging the seed cotton across associated grid bars for separating trash from the raw cotton;
- and
- c) said dryer being mounted upon said cleaner and communicating therewith through an unrestricted opening to permit immediate and substantially unrestricted transfer of the raw cotton from the dryer to the cleaner to effectuate cleaning before the trash recombines with the cotton and while it is remains in a heated condition when trash separation is enhanced.
An improved combined process of reducing the moisture level of raw seed cotton and of cleaning said cotton, said process comprising the steps of:
- a) directing raw seed cotton in an air stream to a vertical dryer;
- b) impacting said seed cotton to break any wads into individual bolls and to thrust them upon at least one inclined shelf to provide a circuitous route for said bolls to further reduce moisture;
- c) substantially reducing the moisture level of the raw seed cotton to approximately 5% in the dryer;
- d) transferring the cotton from the dryer to a cylinder cleaner without compaction or entanglement of trash with the raw seed cotton and passing said seed cotton through a series of cylinder cleaners to enhance the cleaning function of the cleaner.
