摘要（英）：The invention discloses a special leech fluid bed dryer. The special leech fluid bed dryer comprises an aright drying chamber, wherein the upper portion of the drying chamber is provided with a feed port, and a door used for sealing the drying chamber is arranged at the feed port; a partition board used for separating the drying chamber into an upper cavity and a lower cavity is arranged in the middle of the drying chamber; the lower cavity is internally provided with a perforated plate used for carrying leeches, and through holes are densely formed in the surface of the perforated plate; the partition board is provided with exhaust pipes communicating the upper cavity with the lower cavity; each exhaust pipe is provided with an impulse electromagnetic valve which can be opened according to a certain frequency. The special leech fluid bed dryer further comprises a vacuum pump and an air compressor. According to the special leech fluid bed dryer, the impulse type pressure blasting principle is adopted, and tissue fluid in leech organisms rapidly penetrates through cell walls and epidermises of the leeches to evaporate outwards under the action of pressure difference, so the technical problem that the water content of the leeches is hard to reduce due to the fact that the bio-osmosis performance of the epidermises of the leeches is low is effectively solved.
