SZG series double cone rotary vacuum dryer

product description
SZG double-cone vacuum dryer is a new generation drying device developed by our factory in combination with the technology of similar domestic products. The double-cone vacuum adopts two elastic connection methods of belt and chain, so the equipment runs smoothly. The specially designed process fully reflects the good concentricity of the two shafts. The heat medium and vacuum system adopt reliable mechanical seals or rotary joints. On this basis, we developed SZG-A, which can not only stepless speed regulation, but also constant temperature control.

As a professional drying equipment manufacturer, our products are available from high-temperature heat transfer oil as the heat medium, medium-temperature steam and low-temperature hot water. When drying viscous materials, our factory will specially design a "copy board" mechanism or set up balls in the tank for you.

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

Adapt to materials
It is suitable for the concentration, mixing, drying of powder, granular and fiber in chemical, pharmaceutical, food and other industries and materials that require low temperature drying (such as biochemical products, etc.). It is more suitable for drying of easily oxidized, volatile, heat-sensitive, strongly irritating, toxic materials and materials that are not allowed to destroy crystals.

Installation demonstration

Performance characteristics
◎When oil is heated. Use automatic constant temperature control. Can dry biochemical products
◎With mineral raw materials, the temperature can be between 20～160oC.
◎High thermal efficiency, more than 2 times higher than ordinary oven.
◎Indirect heating. The materials will not be contaminated and meet the requirements of "GMP". The equipment is easy to maintain and operate and easy to clean.
◎Recommended process placement demonstration solvent recovery process placement.
