Overview
The SZG series double-cone vacuum dryer is a new generation of vacuum drying equipment developed by our company, integrating domestic similar products. The double-cone vacuum dryer adopts a dual-elastic connection method using belts and pulleys, ensuring more stable operation of the equipment. The professional design fully guarantees perfect coaxiality of the two shafts. The inlet and outlet of the heat medium and the vacuum exhaust system adopt technically reliable mechanical seals or rotating joints. This machine can achieve stepless speed variation and also perform temperature control.
The SZG series double-cone vacuum dryer can be heated using various heat sources such as high-temperature heat transfer oil, medium-temperature steam, and low-temperature hot water. When drying viscous materials, special 'scrapers' can be designed inside the tank or rollers can be placed to prevent material from clumping.
Working Principle
✱ A heat source (such as hot water, low-pressure steam, or heat transfer oil) is introduced into the sealed jacket, and the heat is conducted through the walls to the material being dried
✱ Driven by power, the tank rotates slowly, and the material inside the tank is continuously mixed and heated and dried under vacuum conditions, thereby strengthening the drying process.
✱ The material is in a vacuum state, and the operating pressure drop causes the moisture (solvent) on the surface of the material to reach a saturated state and evaporate quickly. The wet vapor is promptly extracted or recovered by a vacuum pump. The internal moisture (solvent) of the material continuously permeates, evaporates, and is expelled, allowing the material to dry in a very short time.
Adaptability
✱ Suitable for the concentration, mixing, and drying of powdery, granular, and fibrous materials in industries such as chemical, pharmaceutical, and food, as well as materials that require low-temperature drying (such as biochemical products). It is more suitable for drying materials that are easily oxidized, volatile, thermolabile, strongly irritating, toxic, and materials whose crystalline structure must not be destroyed.

Performance Features
✱ When oil heating, automatic temperature control is used, which can dry biochemical products.
✱ For mineral raw materials, the temperature can be between 20~160°C.
✱ High thermal efficiency, more than double that of a general oven.
✱ Indirect heating ensures the material is not contaminated, meeting "GMP" requirements. The equipment is easy to maintain and clean.
✱ Recommended process layout demonstration, solvent recovery process layout.

Technical parameters

Note: For materials with significant volume changes before and after drying, the loading coefficient can be appropriately increased or decreased.
