Title:
DEVICE AND METHOD FOR REMOVING MOISTURE REMAINING IN MATERIAL TO BE DRIED IN FREEZE DRYER EMPLOYING UPRIGHT CYLINDRICAL TUBE AS DRY CHAMBER
Document Type and Number:
Japanese Patent JP2011237136
Kind Code:
A
Abstract:

To provide a means for freezing and drying a material to be dried using a freeze dryer that employs an upright cylindrical tube as a dry chamber, to complete finish drying for sublimating and eliminating unsublimated moisture generated in the material to be dried in a short time at the end of a drying process, by applying irradiation of microwave generated by a magnetron, without disturbing spray of a liquid material to the inner wall surface of the tube or disturbing cleaning/sterilization of the tube which is performed after the dry process.

In the freeze dryer which employs the upright cylindrical tube made of a metal material as the dry chamber, a window hole (a) is formed at a region close to a base end side of a peripheral wall of a duct 7 of an evacuation system, the duct made of a metal material and connected to an upper end side of the tube 1, the window hole is closed air-tightly by a glass plate (b), a magnetron 10 is arranged to the duct 7 at the outside of the window hole (a) so that a microwave projection opening 10a or a microwave emitting hole 13 of a waveguide 12 connected faces the external surface of the glass plate (b).
