product description
SZG double cone vacuum dryer is a new generation drying device developed by our factory in combination with domestic similar product technology. Double cone vacuum adopts belt-chain two elastic connection method, so the equipment runs smoothly. The specially designed process fully embodies the good concentricity of the two shafts. The heat medium and vacuum system use reliable mechanical seals or rotary joints. On this basis, we have developed SZG-A which can be used for both stepless speed regulation and constant temperature control.
As a professional drying equipment manufacturer, our products are made from high-temperature heat-conducting oil, medium-temperature steam and low-temperature hot water. When drying viscous materials, the factory will specially design a “copy board” mechanism or set balls in the tank.

working principle
◎Into the closed interlayer, heat energy (such as hot water, low-pressure steam or heat-conducting oil) is introduced, and heat is transferred to the dried material through the inner casing.
◎ Under the power drive, the tank body rotates slowly, and the materials in the tank are continuously mixed to achieve the purpose of strengthening and drying.
◎The material is in a vacuum state, the vapor pressure drops so that the water (solvent) on the surface of the material reaches a saturated state and evaporates, and is discharged and recovered in time by a vacuum pump. The water (solvent) inside the material continuously permeates, evaporates and discharges to the surface, and the materials are continuously dried in a short time.

Adaptable material
It is suitable for the concentration, mixing, drying and low-temperature drying of powders, granules and fibers in the chemical, pharmaceutical and food industries (such as biochemical products). It is more suitable for drying of materials that are easily oxidized, volatile, heat sensitive, strongly irritating, toxic materials and materials that are not allowed to damage crystals.
