THERE ARE MANY BENEFITS WHICH CAN BE QUALIFIED AFTER AUTOMATION OF SUGAR PLANT. REASONS

There will be considerable reduction in Steam % cane, resulting in savings of Bagasse / Increase in export power in cogeneration power plant by the way of controlling steam to evaporators / pans.

Due to..  Auto Lime Feeding  Optimum Juice Temperature 3. Regulating Vacuum for cake formation IMPROVEMENT IN RBHR AS A RESULT OF REDUCTION IN LOSS OF SUCROSE,

 Regulating Juice level in Evaporator  Regulating steam / Vapour in Evaporator for uniform brix  Regulating fan feed according to conductivity  Maintaining uniform / optimum melt brix and condition of molasses.

There will be substantial reduction in man power resulting in better and effective utilization of man power.

There are many benefits resulting from Sugar Plant Automation which could not be quantified in terms of savings, but would help in improvement of plant performance.

Reduced mill extraction would improve due to fine and continuos control of mill / carrier load / speed

Crushing rate would become more uniform & continuous resulting in smooth operation of plants.

This would also result in reduction of down time of mills & other crushing equipments & eventually reduction of losses / man power.

The Distributed Control System is Fed with enormous amount of data regarding plant operation. The data stored can be retrieved and used for analysis regarding equipment / plant performance.

Automation of Sugar Plant will open flood gates to acquire latest technologies / trends Examples 1. Automatic Generation of Reports 2. Remote Monitoring of Plant Performance.

The entire plant can be Automated OR Plant can be Automated Section Wise
