The invention relates to a light-emitting 
diode dehydrator, which comprises a rack, and has the innovative points that: the light-emitting 
diode dehydrator further comprises a 
dehydration outer 
barrel, a rotating shaft, a 
dehydration inner container and a 
control system, wherein the 
dehydration outer 
barrel is fixedly arranged at the top end of the rack, and a 
barrel cover for sealing is arranged at the barrel top; the rotating shaft is vertically arranged on the rack, the upper part of the rotating shaft extends into the center of the dehydration outer barrel, and the rear end of the rotating shaft is connected with a 
drive motor through a transmission mechanism; the dehydration inner container is used for installing a light-emitting 
diode acid-washing mould to be dehydrated, and is arranged in the dehydration outer barrel, and the center of the dehydration inner container is fixed with the rotating shaft which extends into the dehydration outer barrel; and the 
control system comprises a programmable controller and a control panel thereof, and the programmable controller is connected with the 
drive motor. The invention has the advantages that: when the dehydration is carried out, the two ends of the light-emitting diode acid-washing mould are inserted into an installation groove of the light-emitting diode acid-washing mould of the vertical rack of the dehydration inner container, then the barrel cover is closed, the 
drive motor is started through the control panel, the rotating shaft drives the dehydration inner container to rotate, the water in the light-emitting diode is dehydrated through the 
centrifugal force, so the dehydration is realized. The gas inlet of the side wall of the dehydration outer barrel can be filled with 
nitrogen, so the light-emitting diode is prevented from being oxidized during the dehydration.
