SZG雙錐真空干燥機是我廠在結合國內同類產品技術所開發的新一代干燥裝置，雙錐真空采用皮帶--鏈條兩彈性聯接方式，因而設備運行平穩。特別設計的工藝，充分體現了兩支軸的良好同心，熱媒及真空系統均采用可靠的機械密封或美國技木的旋轉接頭。在此基礎上，我們開發了SZG--A它既可無級調速，又能進行恒溫控制。
本廠可另行在罐內為您特別設計“抄板”結構。
SZG rotary vacuum dryer is a drying device of new generation developed by our factory based on technologies of similar domestic products. The two cone-vacuum adopts belt-chain double elastic connection method, therefore the equipment can run in a stable manner. The specially designed process fully shows the good concentricity of the two shafts. Thermal media and vacuum system all adopt reliable mechanical sealing or rotating connector of American Technology. Based on this, we developed SZG—A which is capable of stepless speed regulating and thermostatical control.
Our factory may provide you with special “shovelling plate” structure additionally inside the tank. 

工作原理 /operating principle
      在密閉的夾層中通入熱能源（如熱水，低壓蒸汽或導熱油）熱量經內殼傳給被干燥物料。在動力驅動下，灌體作緩慢旋轉，罐內物科不斷地混合從而達到強化干燥的目的。
      物料處于真空狀態，蒸汽壓下降使物料表面的水份（容劑）達到飽和狀態而蒸發了，并由真空泵及時排出回收。物料內部的水份（溶劑）不斷的向表面滲透、蒸發、排出、三個過程不斷進行，物料在短時間內達到干燥目的。
Supply heat energy (such as hot water, steam of low pressure or heat conduction oil) into the closed interlayer. The heat will be transferred to materials to be dried by inner shell. The tank body will be driven to rotate slowly. The materials inside the tank are mixed to strength drying purpose.
The materials are under vacuum status. Steam pressure will decrease which make the water on material surface (solvent) become saturated and then evaporate. The water will be discharged and recycled by the vacuum pump immediately. Water (solvent) inside the material is permeated, evaporated and discharged from the surface. The said three processes happen constantly and the materials will be dried in a short period.
