This vegetable dewatering machine uses frequency conversion and photoelectric sensing technology to control dehydration time, spin speed, and start and stop. It offers safe and reliable operation, easy operation, and low vibration and noise. The control system comprises a high-end frequency converter and photoelectric sensors, among other control components. The upper cover opening mechanism utilizes an oil-air hybrid shock-absorbing spring and a viewing window for ease of use. It features frequency conversion regulation, a dehydration timer, and an emergency stop switch. The drive motor is a three-phase asynchronous motor with variable frequency speed regulation, ensuring smooth operation and easy speed adjustment.
