PTD hemp filter centrifuge is to use centrifugal force to accelerate the liquid phase in the solid-liquid mixed liquid out of the rotating drum, and leave the solid phase in the rotating drum, so that the different materials that need to be separated can be accelerated to separate the machine.The operator should fill the filter bag with crushed plant material and places it in the machine. Then, add alcohol until the plant material is submerged. After soaking at low temperature and setting a program to rotate at a low speed in both directions,the active ingredients in the plant are fully extracted. Rotate at high speed and open the bottom discharge valve to discharge the extract.
