[0030] 2. After the first stage of low-temperature constant-temperature aging is completed, the process automatically enters the second stage of temperature rise aging. The temperature rise time curve is accurately calculated by the PLC controller according to the temperature rise formula of the aging process. The opening of the Spirax Sarco electric proportional flow valve 2025 is accurately controlled by PID to ensure that the temperature rise meets the above temperature rise curve at all times, with an error within 0.1 degrees. When the second stage aging time setting value and the third stage aging temperature setting value are reached, the process automatically enters the third stage of medium temperature constant-temperature aging.

[0031] 3. The third stage of medium-temperature constant-temperature aging is automatically carried out according to the corresponding temperature, humidity and time setting values ​​set on the touch screen. The PLC controller automatically adjusts the opening of the Spirax Sarco electric proportional flow valve 2025 based on the deviation between the real-time detection data of the temperature and humidity transmitter 4 and the temperature and humidity setting values ​​of the third stage, thereby realizing online real-time control of the third stage of medium-temperature constant-temperature aging. After completion, the pneumatic steam valve 2024 and the Spirax Sarco electric proportional flow valve 2025 are automatically closed, and an alarm is sounded to remind the staff that the aging process has been completed.
