NEXT GENERATION IN SUGAR INDUSTRY

The new generation of control and monitoring system, developed by Amtech Electronics (India) Ltd, integrates the operation of Feeder table & ACFC (Auto Cane Feeding Control) Automation by using variable frequency drive and Automation system with instrumentation for controlling and monitoring.

Operation of Feeder table & ACFC Automation by using variable frequency drive :

Cane Preparation requires automation of feeder table, cane carrier, knife & mill operation. Raw canes are unloaded on feeder table through can unloader. Level sensor senses the level of cane accumulated. Control system controls the speed of feeder table, cane carrier 1 and 2 based on the Chute level, feeder table level and cutter load. The canes are thoroughly cleaned and cut into small pieces. These cane pieces are dropped over a continuous belt of steel plates called the cane carrier, moving over roller chains. From the cane carrier, these are conveyed to a crusher fitted with a set of revolving knives, and cut into very small pieces. These small pieces in the form of a compact blanket are passed through two roller crushers and four mills.

Features
  • Complete Automation system with ACFC.
  • Infra Red type Donnelly Chute level sensors.
  • Hall Effect type Cane blanket level and Top roller lift sensors.
  • Smooth start/stop operation without any jerks.
  • Very low speed operation is possible.
  • Motor reverse operation possible in critical situation.
  • Alarms for any electrical signals.
  • User friendly HMI with Mimic.
  • Upgradable solution to SCADA level.
  • Precision Motor Load / Pressure Sensors.
  • User friendly customized software, field and data inputs ensures constant load on Mills all the time.

Benefits
  • Assistance from concept to commissioning.
  • Substantial improvement in crush rate.
  • Damage due to choking/jamming at cane preparatory device and 1st mill is totally eliminated.
  • 1st mill extraction is higher with maintained constant levels in Donnelly Chutes.
  • Substantial reduction in wear & tear reduces down time and maintenance cost; improves up time & productivity.
  • Easy troubleshooting.
  • Irregular feed was resulting in fluctuating demand of steam pressure in old system. The new system gives optimum primary extraction due to the uniform cane feed at predetermined rate.
  • Quick and safe commissioning.
  • Qualified after-sales service.
