PURPOSE: To efficiently and sufficiently remove air in fruits in a short time.

CONSTITUTION: A device for removing air in fruits is equipped with a pressure closed container 2 into which water 4 is poured and in which apples 1 can be immersed in the water 4, a pressure-reducing pump 7 for decompressing a space part 8 formed above the water 4 poured in the pressure closed container 2 and a water tank 10 for supplying the pressurized water 4 to the pressure closed container 2. In a state wherein the apples 1 are held in the water 4 poured to height H in the pressure closed container 2, the pressure closed container 2 is decompressed, the decompressed state is retained for a prescribed time, the pressurized water 4 is added to the pressure closed container 2, the pressurized state of the pressure closed container 2 is maintained for a given time to efficiently remove air contained in the interior of the applies 1.
