Abstract
A process for producing a freeze-dried product in a bonded or stratified state by a simple apparatus and by simple operations, without suffering from denaturation by oxygen, enzymes, heat and so on, while maintaining the original quality, properties and so on, by bonding or stratifying materials to be treated before being subjected to freeze-drying; an apparatus therefor; and a freeze-dried product obtained therefrom are provided. The freeze-dried product is obtained by stratifying materials and of the same or a different kind to be treated into a multilayer under interposition of dry ice partly in between the layers; pressing the multilayer from both sides by pressurizing elements and under intermediation by dry ice and to effect bonding of the materials to be treated with each other, while, at the same time, freezing the multilayer; and subjecting the frozen product to vacuum drying.
