FeedForward Control system for Wax Molding Unit Using MatLab/Labview
Paraffin wax is a white or colourless soft solid derivable from petroleum, coal or oil shale, that consists of a mixture of hydrocarbon molecules containing between twenty and forty carbon atoms. It is solid at room temperature and begins to melt above approximately 37 °C (99 °F); its boiling point is >370 °C (698 °F). Common applications for paraffin wax include lubrication, electrical insulation, and candles; dyed paraffin wax can be made into crayons. It is distinct from kerosene, another petroleum product that is sometimes called paraffin.
Paraffin wax is poured into the buckets that are attached to the conveyor belt. The conveyor belt is moved by a motor. A fan is running at 800 RPM for cooling purpose. This system is inefficient due to fixed fan speed and the wax may not be cooled properly. This is because the wax temperature cannot be measured with the classical method of sensors. This will result in production loss and energy loss. In our project we will design a mechanism to solve this problem. We will install sensor to monitor the temperature and control the fan speed using Variable Frequency Drive for optimum control of the unit.
