[0027] Working principle: When using the gasification device, it is only necessary to inject LNG into the tank body 2 through the feed pipe 7, and then turn on the heater 9. The heater 9 will heat the LNG through the heat conduction plate 10. At this time, turn on the motor 3, the motor 3 will drive the shaft 4 to rotate, and the shaft 4 will drive the auger 6 and the stirring rod 5 to rotate. The auger 6 will transport the LNG at the bottom upward when rotating, and the stirring rod 5 will stir the LNG when rotating. After the LNG is heated into gas, it will be discharged from the tank body 2 through the exhaust pipe 8. When the tank body 2 is heated, it will heat the heat conduction coil 13, and the heat conduction coil 13 will heat the water body.
