AUTOMATION IN LEATHER MAKING -A CLEANER PRODUCTION APPROACH

摘要

Leather auxiliaries, chemicals and raw materials are being handled manually in most of the tanneries. The practice give-rises to spilling over of costly chemicals and utilities causing increase in pollution load, financial loss and health hazards. In order to solve this, a computerized programmable logic controller based dosing system is designed and is installed to automate the unit operations in tanning drum. There are five modules which follow the sequences of operation to improve the working atmosphere and reduce the loss. The material handling through engineering inputs results in improved quality control and provides cleaner production.
