Double Roller Ginning Technology & Cotton Quality Evaluation

Gin setting and maintenance are crucial for getting the optimum productivity, reduction in downtime and contamination free lint production. Gin setting and maintenance is an art which can be learned and perfected through theoretical and practical training imparted by reputed institute like CIRCOT. Moreover, the sudden upsurge in growth and modernization of ginning industry has created a high demand for skilled manpower leading to shortage of well trained technicians and machine operators in the industry. The GTC with its appropriate infrastructure imparts hands on instruction in harvesting, cotton quality evaluation, grading, ginning, and baling, testing, marketing etc.
