Abstract

The invention discloses a freeze dryer which comprises a freeze dryer barrel, a feeding door, a door locking device and a water outlet, wherein the feeding door is arranged at one end of the freeze dryer barrel; the door locking device moves so as to prop the feeding door against the freeze dryer barrel; the water outlet is arranged at the other end of the freeze dryer barrel; the freeze dryer barrel is placed in a freezer; a feeding slide rail is fixedly connected with the top end of the inner wall of the freeze dryer barrel; a plurality of feeding plates are arranged in the freeze dryer, detachably connected together, and in slip connection with the feeding slide rail; an ice melting device and an ice collecting device are sequentially arranged in the freeze dryer barrel; and the ice melting device is close to the feeding door. According to the freeze dryer, the feeding plates are detachably connected together, so that corresponding connecting plates can be easily adopted for connecting the feeding plates according to the quantity of materials, and then the materials can be placed on the connecting plates; and through the slip connection between the connecting plates and the feeding slide rail, the feeding plates can be easily put into the freeze dryer barrel and easily mounted, and then the materials can be easily fed.

Description

technical field [0001] The invention relates to the field of freeze-drying equipment, in particular to a freeze-dryer and a defrosting circulation system for the freeze-dryer. Background technique [0002] Freeze dryer is a kind of freeze-drying equipment for freeze-drying materials with moisture. The freeze-dryer adopts a separate design of drying chamber and cold trap, and uses silicone oil as the heat transfer medium.
