Abstract: Disclosed is a freeze-drying apparatus for foodstuffs, medicaments, etc., wherein liquid material is directly and distributively poured into upright cylindrical tubes, then, in its isolated state from external atmosphere for perfect sterilization, the liquid material is frozen with uniform thickness onto inner wall surface of the tubes, with further possibility of uniform heating of the freeze-dried layer. The main body of this apparatus is constructed with upright cylindrical tubes for freezing liquid material onto inner surface of tubes and jackets to surround the outer periphery of each of the tubes in a substantially concentric cylindrical shape, within which to circulate heat medium; then, a duct communicating to the vacuum exhaust system is connected to the upper end side of these tubes, while, a recovery chamber provided with valve is connected to the lower end side of tubes; and an inlet port is defined for feeding liquid material into inner cavity of tubes.

Abstract: This invention is concerned with a distributive ejection apparatus for liquid material in a freeze-drying apparatus for foodstuffs, medicaments, etc., wherein the liquid material adjusted from the starting material for foodstuffs, medicaments, etc. is caused to freeze onto the inner wall surface of the upright cylindrical tube, and the distributive ejection of the liquid material onto the tube at the time of its freeze-drying by sublimation of the moisture content in the material under the vacuum condition may be done in the state of supplying the liquid material over the entire surface of the inner wall surface of the tube with a substantially uniform thickness.

Abstract: Liquid material is caused to freeze as a molded frozen body in a cylindrical form after the shape of the tubular inner wall surface of the freeze-drying apparatus, wherein the moisture content of the molded frozen material is sublimated under the vacuum to freeze-dry the material in the apparatus. A discharge port is defined at the lower end side of the tube, and jet nozzles are disposed, in the inner wall surface of the tube, for ejecting compressed air or gas toward the inner bore of the tube. The molded frozen body of the liquid material as freeze-dried is crushed and pulverized within the tube, by jet current ejected from jet nozzles.

Abstract: Desiccated bulk of liquid material, which has completed its freezing and desiccation in a freeze-drying apparatus, is subjected to pulverization within the machine body of a freeze-drying apparatus.

Abstract: By directly distributing liquid material into upright cylindrical tubes, such liquid material for foodstuffs, medicaments, etc. is kept in its state of being isolated from external atmosphere so as to be perfectly sterilized. That is to say, while simply and adequately securing the controlled cooling of the tube, by means of the heat medium which circulates within the jacket, the liquid material supplied into the tube is caused to freeze with uniform thickness onto the inner wall surface of the tube, with further possibility of uniform heating of the freeze-dried layer.
