The utility model discloses a
vacuum drying device for
ganoderma lucidum
spore powder, and relates to the technical field of
food processing. The
drying device comprises a
drying box, the top of the back face of the
drying box is fixedly connected with a vacuumizer, the top of the drying box is fixedly connected with a rotary stirring
assembly, the top of the rotary stirring
assembly is fixedly connected with a soaking drying
assembly, and the rotary stirring assembly comprises a protective cover fixedly connected to the top of the drying box. The problems that a traditional drying
machine is uneven in heating and conidial
powder is caked are solved, in the rotary stirring assembly, a driving motor drives a transmission shaft to enable a containing disc to rotate, meanwhile, a stirring rod is driven by a driving wheel, a driven wheel, a worm and a worm wheel to rotate, the
ganoderma lucidum conidial
powder is stirred,
caking is avoided, and the drying efficiency is improved. A hot-
air blower of the soaking and drying assembly uniformly feeds hot air into a drying box through an arc-shaped
pipe and a
flow divider, all parts of the
spore powder are uniformly heated in combination with rotary stirring, the drying effect is effectively improved, and stable product quality is guaranteed.
