The tray assembly 312 receives the tray through the tray main board and moves the tray into the receiving area of the skip 32, and then the skip 32 is driven to move by the manual grabbing handle 322 to transfer the empty tray to the dedicated storage area. Finally the skip 32, which does not carry a peripheral turntable, is replaced in the skip position.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present utility model should be included in the present utility model.
