Abstract
Sterilizer is an instrument that maintains saturated steam for a period of time at high temperature and under pressure. It is used to sterilize medical equipments and lab equipment by destroying potentially infectious agents. An effective autoclave or sterilizer must contain dry saturated steam. In order to achieve this air must be removed from both the load and the chamber. This can be accomplished number of ways. Existing method of sterilization comprises, Pre-vacuum, water level inside the boiler are carried out by operator. Other process like Pre-Vacuum, injection of jacket steam inside the chamber, drying is manually done by the operator through multiport operating valve situated at the top of the unit. Pressure inside the jacket and chamber are displayed on Bourdon type pressure gauges and temperature on analogue meter. These all process are carried out manually resulting human errors and time consuming. To overcome this problem we designed sterilization process with the help of Programmable Logic Controller (PLC).
