  • Freeze vacuum drying apparatus and freeze vacuum drying method
    Patent number: 11112176
    Abstract: A freeze vacuum drying apparatus includes: a spraying unit; a pipe unit; a heating unit; and a collection unit. The spraying unit sprays a raw material liquid into a vacuum chamber. The pipe unit has a non-linear shape, includes a first opening end and a second opening end, and traps frozen particles via the first opening end, the frozen particles being formed by self-freezing of liquid droplets formed by spraying the raw material liquid into the vacuum chamber. The heating unit heats the frozen particles in the pipe unit for sublimation drying, the frozen particles moving in the pipe unit from the first opening end toward the second opening end by kinetic energy produced during spraying. The collection unit collects dried particles that are formed by sublimation drying of the frozen particles in the pipe unit and released from the second opening end of the pipe unit.
