There are five control modes, including manual control, electrical control, computer control, computer semi-automatic control and computer full-automatic control (remote control).

Manual control type:

All valves and pumps are manually controlled, including water adding, heating, heat preservation, cooling and other processes.

Electrical semi-automatic type:

The pressure is controlled by an electric contact pressure gauge (one meter controls two valves, air supply valve and exhaust valve), and the temperature is controlled by a sensor (PT100) and an imported temperature controller (with an accuracy of 0 ± The cooling process was operated manually.

Computer semi-automatic type:

PLC and text display are used to process the collected pressure sensor signal and temperature signal, which can store the sterilization process with high control precision and temperature control up to 100 ℃ ± 1 ℃, (mainly control air supply, exhaust, temperature and time) the temperature process is operated manually.

Computer automatic control type:

The whole process is controlled by PLC and touch screen, which can store the sterilization process. The operator only needs to press the start button, which will automatically prompt after sterilization, and the temperature control precision can reach ± 0.5℃,。（ The whole sterilization process has been digitalized and mechanized（ Remove the incoming and outgoing goods and open and close the boiler door)

Computer automatic control type (remote control type)

On the basis of semi-automatic computer, the whole machine is automatically connected with the front and rear conveying lines. The whole machine has the functions of automatic feeding and discharging, automatic opening and closing of the boiler door, and the guide rail in the boiler can automatically retract and retract back and forth. (the whole machine has achieved digitization and mechanization) it can form remote control or operation, which is the basis of unmanned operation appraisal in the workshop. The use of remote control saves time for after-sales service.
