Sugar Mill Automation YU Technologies Pvt. Ltd. Registered Office: 315, A1, 22, Manishanagar, Off Sahyadrinagar, Sangli – 416 416, Maharashtra, India. HO & Works: B 8/5, MIDC, Miraj, 416 410, Distt: Sangli, Maharashtra, India. T: + 91 233 6451803 – 6; F: +91 233 2644042 E: info@yutech.in W: www.yutech.in Servicing the Sugar Industry since 1978 Agenda • Need for Automation • Automation Approach • Mill Automation Examples • Why choose YUTECH • Case Study and Value Analysis • Concluding Remarks www.yutech.in; sale@yutech.in Need for Automation Energy savings by Save costs and money improved throughput, by optimising the gain in performance resources like Steam, and efficiency Fuel, Power and water. Achieve the minimum cost of operations by streamlining operations and increasing Throughput www.yutech.in; sale@yutech.in The Purpose of Mill Automation Basic Requirement: • Safety of the Cane Feeding and Milling Equipment. • Prevention of Overloading of Feeding and Milling Equipment. • Prevention of Jams and Choking in Cane Feeding and Milling Equipment. • Facilitate continuous operation. • Reduction and Possible Elimination of Stoppages due to Human Error. • Early indications of Faults. Optimization: • Maintaining optimum load on the Preparatory Devices and Mills. • Maintaining Continuous Positive Feeding at all times. • Maintaining Uniform Steam / Power Demand over the entire Mill House. www.yutech.in; sale@yutech.in Automation Approach Common Industrial Activities like Steam Generation or Process Plants share common engineering parameters like Pressure, Temperature, Flow and pH. Milling is completely different from these activities. Therefore the Automation approach also differs greatly from other common processes. We would like to concentrate on this Approach. www.yutech.in; sale@yutech.in Mill House Automation Systems Interlocks, Protection and Alarming Systems: • Automatic Interlocking System between Bagasse Carrier, Inter Carriers, Mills, Rake and Main Cane Carriers, Preparatory Devices, First or Auxiliary Cane Carrier meaning if any equipment stalls or trips then all preceding feeding equipment will stall. • Bearing Temperatures Of all Mills, Cane Preparatory Devices, Cane Carriers are sensed and Alarms are generated if Temperature of any bearing rises above prescribed limit pin pointing the device. • Any other Customized Factory Specific Application will be implemented. www.yutech.in; sale@yutech.in Understanding the Milling Process SUGAR MILL INPUTS AND OUTPUTS STEAM BAGASSE CANE MILL ELECTRICITY SUGARCANE JUICE EXHAUST STEAM MACERATION WATER www.yutech.in; sale@yutech.in Understanding the Milling Process SUGAR FACTORY LAYOUT BOILER STEAM BAGASSE CANE POWER MILL TURBINE ELECTRICITY EXHAUST SUGARCANE STEAM JUICE EXHAUST STEAM SUGAR MACERATION WATER PROCESS STEAM CONDENSATE www.yutech.in; sale@yutech.in Understanding the Milling Process SUGAR FACTORY LAYOUT (TURBINE MILL DRIVES) BOILER STEAM FEED BAGASSE WATER CANE POWER MILL TURBINE ELECTRICITY EXHAUST SUGARCANE STEAM JUICE EXHAUST STEAM
