Principle：

◆ The continuous vacuum plate dryer is developed and designed by our company independently. It is now as advanced as the ones produced overseas. The material is continuously and quantitatively sealed and then added to the vacuum plate dryer. As the boiling point of the material decreases under the vacuum environment, the material can be dried at a low-temperature state. As the paddle blades continuously stir the material and push it forward, the surface of the material keeps getting renewed, which further accelerates the drying rate. Meanwhile, the humid air (or solvent) is pumped out of the system by a vacuum pump, so that the material can be continuously dried and cooled while the solvent can be recovered under the vacuum condition. This type of drying equipment is mainly used for continuous drying, reaction or cooling of materials that are heat sensitive, toxic, or easy to oxidize, and materials that require solvent recovery.

Features：
◆ Under the high vacuum condition, continuous or semi-continuous feeding and discharging of materials is maintained.
◆ Sealed operation; especially suitable for drying (cooling) of highly toxic materials, materials that are easily oxidized, or materials that require solvent recovery.
◆ Continuous low temperature drying equipment; condenser is added to recover organic solvent.
◆ Low energy consumption, high efficiency, good safety performance, continuous operation and convenient maintenance.
◆ Under the vacuum condition, continuous feeding and discharging is maintained. The entire operation can be completed in a sealed environment. The maximum vacuum level can be maintained within -0.098Mpa.
◆ In 2007, our company designed and produced the vacuum plate dryer for aramid fiber specifically, which has achieved great success.
