Dilute Acid Delinting
Dilute Acid Delinting is the most efficient and environmentally friendly method used in the removal of residual lint from cotton planting seed. A precisely controlled amount of specially formulated sulfuric acid mix solution is applied to the fuzzy seed in the Stainless Steel Reactor. By limiting the acid applied, less fuel is used in the drying phase, noxious residue is held to a minimum and production of black seed is enhanced. The Dilute Acid delinting method can be completed using two different methods designed to fit the production needs of the operator.
The L.T. Kincer MLK Dilute Acid Delinting System is a batch system that is suited to production rates from 1,000 lbs. per hour to 6 Tons per hour. Smaller batches and larger production are possible. Please contact L.T. Kincer Co. for details.
The L.T. Kincer Continuous Acid Delinting System is a high production system that is suited to production rates from 4 Tons per hour up to 12 tons per hour. Larger production rates are possible. Please contact L.T. Kincer Co. for details.
HCL Acid Delinting
HCL Acid Delinting is a more primitive method used in the removal of residual lint from cotton planting seed. Fuzzy cottonseed is dried and warmed in a continuous drier and measured into a seed charger. The seed charger conveys the seed into the pre-heated and rotating delinting drum where vaporized and pressurized HCL gas is injected into the delinting drum. The HCL gas reacts with the lint and weakens the fiber. Once the fuzzy seed has been exposed to the HCL gas, it is transferred to a set of buffing drums that tumble the seed as the reaction occurs. Lint is removed in the buffers through a mechanical scrubbing action that seperates the weakened fibers from the hard seed coat. Some of the seperated lint is pulled from the buffing screens pneumatically and transferred to cyclones or a filter baghouse. The remainder of the lint collects in the hopper below the buffering reels. This lint is collected and transferred to the trash bin by screw conveyors or an air system. Delinted seed from the buffers is neutralized with the ammonia before processing in the conditioning and treating equipment.
Mechanical Brush Delinting
Mechanical Brush Delinting for planting seed is performed in an L.T. Kincer Co. patented KINCO Brush Delinter. While the production rates are significantly lower than Acid Delinting, the residual lint is not destroyed in the process. Delinting occurs as the fuzzy seed is scrubbed through the interior of a perforated screen cylinder. The scrubbing action of the interior brushes rubs the seed across the perforations allowing the airflow to remove the lint from the machine. Mechanical Brush Delinting requires more energy that Acid Delinting and is not as complete. Each seed will show some lint remnants at each end of the oval shaped seed. Due to the abrasive action of the brushes, care must be taken to prevent overheating the seed and/or damaging the seed coat. Mechanical Brush Delinting does not use any chemicals and can produce a small quantity of useable low grade lint as a by-product.
