Operating principle
This equipment is a vacuum chamber where a material conveying guide belt(Teflon PTFE) is fixed in it.Materials are distributed continuously on the guide belt after they pass through the vacuum continuous distributor on the top of the equipment. Based on material propertise,the material distribution thickness is adjustable (3mm-30mm).The guide belt keeps conveying slowly to the other end,with the heating zone under it to provide drying heat for the belt,so the materials on the belt evaporate water during convoying constantly and the vapor is quickly removed by vacuum. The materials will automatically fall on the second-layer guide belt when they reach the end of the equipment,and they will repeat the operation again and again until they meet the drying requirements. Multilayered structure can be designed according to materical process requirements. With(40℃-180℃) temperature for each layer and adjustable running speed, this equipment is suitable for drying curve required by all kinds of materials and realizes mild drying. Finally the mater ials fall into the conveying chute at the discharging end,conveyed to the exit hole by the screw conveyor,and then delivered to the material-receiving barrel after grinding and sieving by the pulverator with adjustable mesh (20-200). The drying is finished after continuous discharging.
