It is a kind of to accelerate freeze-drying when being related to freezing the product with skin one kind to generate using microwave energy, the generation of broken skin, the pressure for reducing pressure generates rupturing and has freezed to allow to distil with a kind of, first microwave power is at least under 30 power density to acquisition initial microwave power density is generated, applying the second microwave power and generating generating temperature is more than threshold value, wherein the second microwave power is less than the first microwave power.
