Cleaning and sterilizing, custom made boiler, steam, slider crank mechanism.Abstract
In this work a system utilizing a dry steam (vapor) for cleaning and/or sterilizing and other processes of the same kind is developed. A custom made compact boiler with a heat source is utilized for the generation of steam. A reservoir is provided that contains a mixture of water, cleaning agents or other chemicals. A motor driven pump is used for pumping the liquid mixture into the boiler which is then immediately vaporized and subsequently discharged through a nozzle. The system is configured in a manner that it can be operated electrically under manual control. The interior of the boiler is shaped so that it helps in enhancing the flashing of the liquid. The speed of the pump, flow rate of water, size of boiler, and applied heating temperature are chosen such that a steady flow of steam can be maintained from the nozzle at a desired pressure and temperature.
