Drying method of the object to be dried in a freeze-dried and the freeze-drying apparatus

摘要

[Challenge] the end of the dry precision higher detection, is to provide a drying method and the freeze-drying apparatus of the object to be dried in a freeze-dried. The A object to be dried 1 frozen, high absorptivity of radiation heat with infrared heater 12, and the thermal conductivity is frozen after mounted to a good container 2 is equipped with a plurality of containers in the vacuum vessel 6 The pressure inside the vacuum vessel after the vacuum pressure sublimation occurs material to be dried, heating the object to be dried mounting the container by a far infrared heater, causing the heat conduction in the material to be dried from the vessel and sublimating the material being dried under pressure of vacuum tank caused to dry and the temperature of the surface of the vessel was measured by a thermocouple 3, the temperature setting is Celsius 30 component breakdown does not occur according to the type of the surface temperature of the dried product of said container with a that it has reached the specified temperature in the range of 90 degrees Celsius degrees, the method of drying object to be dried in a freeze-drying, characterized in that to complete the drying process by pressure restored to reduced pressure to atmospheric pressure. .BACKGROUND
