Application of double cone rotary vacuum dryer to maintain a good development prospects, the vacuum pump is pumped through vacuum exhaust pipe, using a vacuum system vacuum while continuously heating the material to be dried, the material internal moisture diffusion through the pressure differential or concentration difference surface pressure cylinder body is always lower than the atmospheric pressure, the number of gas molecules, low density, low oxygen. Changzhou City Drying Equipment Co., Ltd. Jiangsu double cone rotary vacuum dryer at a pressure gradient effect, and soon moved to the surface of the water, will not harden the surface, the viscosity varies with its moisture, viscosity material can agglomerate into blocks, and cylinder wall adhesion, easy adhesion of the filter and the wall after drying.
