|発明の名称||LYOPHILIZED MATERIAL, METHOD AND DEVICE FOR PRODUCING THE SAME|
PROBLEM TO BE SOLVED: To provide a method and device for producing lyophilized materials, capable of efficiently removing a large amount of carbon dioxide gas generated by the sublimation of dry ice from a cooled and frozen treated materials and water content from the frozen materials even by using the dry ice as a cooling medium, capable of preventing the adhesion among the treated materials each other by drying the treated materials while rotating them and shortening the drying time of the frozen materials, and also capable of obtaining a high quality lyophilized materials, since it is possible to uniformly heat the frozen materials, and the lyophilized materials obtained by the above method.
SOLUTION: The method and device for producing a lyophilized materials is provided by housing a container 4 for the treated materials, having an air- ventilating property and for housing the frozen treated materials cooled by the dry ice, in a rotary cage 3 in a lyophilizing device main body 1, heating the treated materials by a heating device 6 under a vacuum condition, and sublimating the dry ice and water content contained in the treated materials to obtain the lyophilized materials.
