Abstract
[Object] To provide a freeze-drying apparatus and a freeze-drying method, which are capable of increasing a drying efficiency of frozen particles. [Solving Means] The freeze-drying apparatusincludes a freezing chamberinto which a raw material fluid F is injected. During the injection of the raw material fluid F, after the injection of the raw material fluid F, or for a time period covering the start to the termination of the injection of the raw material fluid F, a shelfis vibrated in a horizontal direction due to an actuation of vibration generators. With this, the frozen particles deposited on the shelfare evenly diffused on the shelfin such a manner that a deposition thickness thereof becomes smaller or a single layer thereof is formed. With this, a freezing efficiency and the drying efficiency of individual particles are promoted.
