AI Technical Summary
The existing vacuum freeze dryer has a fixed material rack design, which cannot be rotated under vacuum, resulting in inconvenience in operation. In particular, when the equipment is placed against a wall, the eggplant-shaped bottles on the side of the material rack against the wall are difficult to disassemble and assemble.
A rotatable vacuum freeze dryer was designed, with a rotating docking structure between the material rack and the vacuum device. The material rack has multiple hanging parts and is connected to the vacuum device through a vacuum channel. The material rack can rotate under vacuum, allowing the hanging parts to change orientation and position. Combined with the design of rotating rods and crossbars, the operational flexibility is improved.
It enables stable rotation of the material rack under vacuum, allowing users to easily assemble and disassemble eggplant-shaped bottles on the spot, solving the operational difficulties when the equipment is placed against a wall, and improving the flexibility and efficiency of use.

Abstract
Claims
1. A rotatable vacuum freeze-dryer characterised in that: The device includes a main unit and a material rack. A vacuum device is fixedly installed inside the main unit. A rotating docking structure is provided between the material rack and the vacuum device. The material rack is provided with multiple hanging parts. A vacuum channel is opened inside the material rack. The vacuum channel connects the vacuum device and the hanging parts. The material rack is adapted to rotate relative to the main unit to change the orientation and position of the hanging parts.
2. A rotatable vacuum freeze-dryer as claimed in claim 1, wherein: The rotating docking structure includes a first sleeve, a second sleeve, and a sealing ring. The first sleeve and the second sleeve are adapted to be nested together. The sealing ring is fitted and snapped between the first sleeve and the second sleeve. A quick-connect flange is provided on the circumference of the inner side of the first sleeve. The quick-connect flange is adapted to limit the nesting depth of the first sleeve and the second sleeve.
3. A rotatable vacuum freeze-dryer as claimed in claim 2, wherein: The second sleeve is provided with a clamp on its periphery, and the outer periphery of the quick-connect flange extends toward the clamp to form a connecting cover. The clamp is adapted to be placed inside the connecting cover, and the connecting cover is provided with a detachable fixing pin. The fixing pin is adapted to prevent the clamp from detaching from the connecting cover.
4. A rotatable vacuum freeze-dryer as claimed in claim 3 wherein: The number of fixing pins is multiple, and the fixing pins are movably disposed on the connecting cover. The fixing pins are adapted to be close to or away from the surface of the second sleeve, and the fixing pins are adapted to abut against the surface of the second sleeve to change the included angle between the surface of the connecting cover and the surface of the second sleeve.
5. A rotatable vacuum freeze-dryer as claimed in claim 1, wherein: The rotating docking structure is located inside the host; the host has an openable side panel on its side, and the rotating docking structure is adapted to be exposed at the opening of the side panel.
6. A rotatable vacuum freeze-dryer as claimed in claim 1, wherein: The material rack includes a rotating rod and a crossbar. The rotating rod is rotatably connected to the vacuum device. There are one or more crossbars, which are parallel to each other and spaced apart on the rotating rod. Multiple hanging parts are spaced apart on the crossbars.
7. A rotatable vacuum freeze-dryer as claimed in claim 6 wherein: Multiple hooking parts are provided at intervals on both the front and rear sides of the crossbar. The main unit has an operating side on its side. The material rack is adapted to rotate so that the hooking parts on the front and rear sides of the crossbar are exposed to the operating side.
8. A rotatable vacuum freeze-dryer as claimed in claim 1, wherein: The host is placed on the ground. During the rotation of the material rack, the projection of part of the material rack on the ground is adapted to protrude beyond the projection of the host on the ground. The material rack is adapted to rotate to change the protruding position of the projection, or to make the projection not protrude beyond the projection of the host on the ground.
9. A rotatable vacuum freeze-dryer as claimed in claim 8, wherein: The host is provided with an operating side and a support side around its perimeter. The projection of part of the material rack on the ground is adapted to protrude from the projection of the support side of the host on the ground. The material rack is adapted to rotate so that the protruding position of the projection moves to another support side or the operating side, or so that the projection does not protrude from the projection of the host on the ground.
10. A rotatable vacuum freeze-dryer as claimed in claim 1, wherein: When the material rack rotates, it is adapted to not extend from the main unit, or to extend from one side of the main unit, or from the opposite sides of the main unit.
