LDG series single cone spiral vacuum dryer -- structure and characteristics  

1. The working process of spiral single cone vacuum dryer is intermittent batch operation. After wet material enters the silo, it is heated through the jacket of cylinder wall and the inside of propeller, so that the heat area can reach 140 percent of the entire container area, and the material can be heated and dried.  And select the corresponding cone mixer model (working volume) to achieve the ideal drying effect.  The mixing dryer with the up-drive structure has the characteristics of sufficient space and convenient maintenance while drying and mixing capacity.  

2, smooth operation, crystal shape protection:  

Single spiral cone vacuum drying machine in the process of drying and mixing process does not use any tools, only using the cone type mixing the revolution of the screw and the rotation, which makes the material in addition to stir from the spiral ascending and constant shear and scattered, the material can get motion bin, and can make the material in addition to ascend from the propeller,  Without any other external force extrusion, avoid the ineffective friction between powder and equipment and powder grains, and ineffective friction is often the main factor leading to the destruction of material crystal shape.  This is also the fundamental reason why the screw vacuum dryer can keep the crystal shape of materials intact in the process of operation.
