Parametrical controlled apparatus for evaporation of oxidant or oxidant solution for sterilization of object, has storage tank and flow regulating valve is provided in pipe which regulates supply of oxidant or oxidant solution to evaporator

摘要

Parametrical controlled apparatus has a storage tank (20), which contains liquid oxidant (22) or oxidant solution. Evaporator, under normal operating conditions is connected with storage tank by a pipe. Flow regulating valve (30) is provided in pipe which regulates supply of oxidant or oxidant solution to evaporator (40). Sterilization container is attached at exhaust gas line (54) and connected with vacuum pump under normal operating conditions. The vacuum pump is in the condition to produce a negative pressure in the sterilization tank (60). A pressure sensor is provided in the sterilization tank for the determination of the partial pressure of vaporous oxidant or the vaporous oxidant solution. A microprocessor (80) receives a signal from the pressure sensor and is so programmed that it determines the amount of the oxidant or the oxidant solution parametrical from the pressure signal in the sterilization vessel.
