A technology for protecting a valve seat inside a collection tank from the adherence of frozen particles in a vacuum freeze-drying apparatus and a frozen particle manufacturing method. The inside of a vacuum tank and a collection tank are vacuum evacuated; a raw material liquid is injected into the vacuum tank to produce frozen particles; and the frozen particles are piled up on a surface of a heating/cooling shelf. When the frozen particles on the heating/cooling shelf are transferred into the collection tank through the inside of an auxiliary pipe, the frozen particles do not adhere to a valve seat which surrounds an opening of a main pipe inside the collection tank.

[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.
