[0032] The suspended unit comprises a suspended seat 3, the inserting shaft 4 is slidingly connected in the suspended seat 3, and the suspended seat 3 is provided with a control member, which is used for taking the trellis fungus materials off the inserting shaft 4 after the trellis fungus materials are freeze-dried.

[0033] The control member comprises a liquid storage groove 302 arranged on the suspended seat 3, the liquid storage groove 302 is filled with water, a through shaft 5 is slidingly connected to the suspended seat 3, the upper end of the through shaft 5 is fixedly connected with a floating capsule 501, the floating capsule 501 is located in the liquid storage groove 302, the through shaft 5 is fixedly connected with a connecting disc 504, and the connecting disc 504 is connected with the inserting shaft 4 through a lever member; wherein the through shaft 5 is sleeved with a reset spring 503, and the two ends of the reset spring 503 are connected to the connecting disc 504 and the suspended seat 3 respectively.

[0034] When the liquid storage groove 302 is filled with water, the water is in a liquid phase, the through shaft 5 is moved upward under the action of the buoyancy of the floating capsule 501, and the reset spring 503 is stretched; when the trellis fungus materials are frozen, the water in the liquid storage groove 302 also changes into a solid phase, and the through shaft 5 is frozen and fixed; when the water in the trellis fungus materials is dried, the water in the liquid storage groove 302 also changes from a solid phase into a gas phase, at this time, the through shaft 5 is moved downward under the action of the reset spring 503, the connecting disc 504 is moved upward under the action of the lever member, the lower end of the inserting shaft 4 is separated from the trellis fungus materials, and the trellis fungus materials fall into the placing bin 201, so that the placing bin 2 is conveniently removed.
