[0002] A vacuum degasser is a device that uses vacuum suction to remove non-condensable gases from liquid feed. The function of a vacuum degasser is to remove air from the liquid feed, inhibit browning, oxidation of pigments, vitamins and nicotine substances, and prevent quality degradation; remove suspended particulate gas attached to the liquid feed, inhibit the floating of particles, and maintain a good appearance; prevent bubbling during canning and high-temperature sterilization that affects sterilization; and reduce corrosion to the inner wall of the container, playing an anti-corrosion role.

The lower end of the vacuum degassing tank 5 is fixedly connected to the input end of the water pump 3 through a three-way drainage pipe 13, and two drainage control valves 7 are provided on the three-way drainage pipe 13. The output end of the water pump 3 is fixedly connected to the outlet pipe 20, and the end of the outlet pipe 20 away from the water pump 3 is fixedly connected to the return water pipe 2. The upper ends of the two vacuum degassing tanks 5 are commonly fixedly connected to a three-way exhaust pipe 8, and the three-way exhaust pipe 8 is provided with two automatic exhaust valves 9 and two air release valves 10. By setting the three-way The water inlet pipe 12, the three-way drainage pipe 13, the water outlet pipe 20, the three-way exhaust pipe 8, the water inlet control valve 6, the drainage control valve 7, the automatic exhaust valve 9 and the air release valve 10 are switched on and off to control different water inlet control valves 6, drainage control valves 7, the automatic exhaust valve 9 and the air release valve 10. It is possible to achieve that while one vacuum degassing tank 5 is being filled with water, the water pump 3 extracts water from another vacuum degassing tank 5. When the water of one vacuum degassing tank 5 is extracted, the other vacuum degassing tank 5 is filled with water again. The cooperation of several solenoid valves on the equipment allows the water pump 3 to operate non-stop, greatly improving the efficiency of the vacuuming of the equipment and effectively avoiding intermittent operation of the water pump 3, thereby saving electricity.

[0026] Specifically, a control device 14 is fixedly installed on the upper end of the protective chassis 1, and the water inlet control valve 6, the drainage control valve 7, the automatic exhaust valve 9 and the air release valve 10 are all connected to the programming controller signal in the control device 14. Through the programming controller in the control device 14, the water inlet control valve 6, the drainage control valve 7, the automatic exhaust valve 9 and the air release valve 10 can be programmed and controlled to achieve automatic operation.
