When the hot water is discharged from the pressurizing machine 25 and enters the heating cavity 111 of the heating plate 11 along the W-shaped pipe 23, the liquid separator 22 and the third infusion tube 2, the heating plate 11 will be heated, and the moisture in the food in the freeze-drying chamber 1 will be heated and sublimated by the heating plate 11. The pressurizing machine 25 increases the flow rate of the hot water, so that more hot water can contact the heating plate 11 for heat exchange in the shortest time, thereby improving the heating efficiency.
