Development of an Automatic Water Temperature Control Unit for Sprinkling Bagasse

Abstract

The purposes of development of an automatic water temperature control unit for sprinkling bagasse were 1) to design and build an automatic water temperature control unit for sprinkling bagasse 2) to find the efficiency of an automatic water temperature control unit for sprinkling bagasse by comparing the manual adjustment and the automatic water temperature control set. The high-temperature water from the boiling tank was sent to the tank by a motor pump to sprinkle bagasse to excrete the sweetness. The temperature of hot water has to be constant. The old method uses a man to adjust the hot water valve, which makes the motor pump runs full capacity. The manual adjustment of the valve can reduce water flow but it cannot reduce the current of electric motor. The electric motor still operates at full speed causing a loss of electrical energy. To make the bagasse matting more efficient and convenient, an automatic water temperature control unit is used by using Digital Indicator Controllers to receive commands from RTD (Resistance Temperature Detector) meters or temperature sensors to process and send out commands. In order to the Inverter to adjust the speed of the motor to adjust the hot water into the tank before sprinkling the bagasse. The experimental results showed the electricity consumption of the automatic water temperature control unit during the adjustment of the water valve. From the test of 1 hour, the motor current of the automatic bagasse sprinkle water temperature the controller changes according to the speed of the water pump motor. The water pump motor uses an average reduction of 2,995 watts/hour of energy, which is less than adjusting the motor valve of the pump by hand with electrical energy The average is 4,056 watts/hour, that is, it can reduce electricity consumption by 26.16 percent.
