ABSTRACT:
An apparatus and method for cooking and dispensing starch to a commercial laundry machine comprising a mixing tank for mixing and storing a starch and water solution which is attached to a means for discharging the starch and water solution to a heat exchanger. The heat exchanger is a shell and tube heat exchanger, either one-phase or two-phase, used for cooking the starch and water solution to form cooked starch. As the starch and water solution is passed through the tube side of the heat exchanger, it is cooked using heat energy from a heating source contained in the shell side of the heat exchanger. The cooked starch is then dispensed through a manifold valve system to one or more commercial laundry machines. After the cooked starch is dispensed, a solenoid valve opened to flush the apparatus with fresh water. A programmable computer receives a request from a commercial laundry machine for a desired starch level, discharges the starch and water solution through the apparatus for cooking, and dispenses the cooked starch to the requesting laundry machine through a series of discharge and manifold valves. The programmable computer controls the solenoid valve for flushing the apparatus with water, the discharging means and a means for recirculating the starch and water solution.
