The water bath sterilization cabinet uses high-temperature circulating water as the sterilization medium to carry out water spray heating, sterilization and cooling of articles. In the whole working process, the sterilization medium runs in a closed circulation system, which effectively prevents secondary pollution. The equipment has wide temperature control range and good temperature uniformity. It is widely applicable to the sterilization of various specifications of glass bottles, plastic bottles and soft bags in the pharmaceutical industry.

The working process of water bath sterilization cabinet is as follows:

(1) Water injection stage: place the drugs to be sterilized in the sterilization cabinet according to a certain arrangement, close the sealing door, and then inject RO water into the cabinet.

(2) Rapid temperature rise stage: when RO water reaches a certain height, close the valve of RO water, start the circulating water pump, and open the large and small steam valves to heat the RO water circulating in the cabinet through the heat exchanger.

(3) Sterilization stage: when the temperature of circulating water reaches the process set temperature (e.g. 100 ¡æ), open the small steam valve at intervals to control the sterilization temperature in the cabinet. The time to stay at this stage is the sterilization time in the general process requirements.

(4) After completing the sterilization stage, close all steam valves and open corresponding valves to relieve pressure in the cabinet.

(5) Open the corresponding valve to clean the semi-finished products in the cabinet twice.

(6) The cabinet door can be opened until the relative pressure in the cabinet is zero, the circulating water is discharged, and the drug temperature is lower than 30 ¡æ.
