Product Overview
The SZG Double-conical Vacuum Dryer is our factory's new generation drying equipment developed by combining the technology of similar domestic products. The double-conical vacuum employs a belt-chain two-elastic connection method, ensuring smooth operation of the equipment. The specially designed process fully demonstrates the good concentricity of the two shafts, with the heat medium and vacuum system both utilizing reliable mechanical seals or U.S. technology rotating joints. On this basis, we have developed the SZG-A, which features both stepless speed adjustment and constant temperature control.
As a professional manufacturer of drying equipment, our products cover a full range from high-temperature thermal oil as the heat medium, to medium-temperature steam and low-temperature hot water. For drying sticky materials, we will specially design a "scraping blade" mechanism or install ball bearings inside the tank for you.
Operating Principle
Heat energy (such as hot water, low-pressure steam, or heat transfer oil) is introduced into the sealed sandwich layer, where the heat is transferred to the material to be dried through the inner shell.
Under power drive, the drum rotates slowly, continuously mixing the material inside to achieve the purpose of enhanced drying.
The material is in a vacuum state, causing the steam pressure to drop and the moisture (solvent) on the surface of the material to reach saturation and evaporate, which is then promptly removed and recycled by the vacuum pump. The moisture (solvent) inside the material continuously penetrates, evaporates, and is expelled, with these three processes occurring continuously. The material achieves the drying goal in a very short time.
Performance Features
During oil heating, automatic temperature control is used to dry biochemical products.
◎and mineral raw materials, with temperatures ranging from 20 to 160oC between.
High thermal efficiency, more than double that of a standard oven.
Indirect heating. Materials remain uncontaminated, meeting "GMP" requirements. Equipment maintenance and cleaning operations are simple and easy.
Recommended process placement: Demonstration of solvent recovery process placement.
Material Compatible
Suitable for the concentration, mixing, drying, and low-temperature drying of powders, granules, and fibers in industries such as chemicals, pharmaceuticals, and food, particularly for materials that are prone to oxidation, volatility, heat sensitivity, strong irritation, toxicity, and those that require the preservation of crystal structures.

Specs and Parameters

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