Product Details

Product Overview
The SZG double-cone vacuum dryer is a new generation drying device developed by our factory by integrating technologies from similar domestic products. The double-cone vacuum system adopts a belt-chain dual elastic connection method, ensuring stable operation of the equipment. The specially designed process fully demonstrates the excellent concentricity of the two shafts, and both the heat medium and vacuum systems utilize reliable mechanical seals or rotary joints based on American technology. Building on this foundation, we have developed the SZG-A, which offers both stepless speed regulation and constant temperature control.
As a professional manufacturer of drying equipment, our products cover a full range of heat media, from high-temperature thermal oil, medium-temperature steam, to low-temperature hot water. When drying sticky materials, we will specially design a "scraper plate" mechanism or install rollers inside the tank for you.
Working principle
◎ Introduce a heat source (such as hot water, low-pressure steam, or thermal oil) into the sealed interlayer, and the heat is transferred through the inner shell to the material being dried.
◎ Driven by power, the tank rotates slowly, continuously mixing the materials inside to achieve enhanced drying.
◎ When the material is in a vacuum state, the decrease in vapor pressure causes the moisture (solvent) on the surface of the material to reach a saturated state and evaporate, which is then promptly discharged and recovered by the vacuum pump. The moisture (solvent) inside the material continuously undergoes three processes: permeating to the surface, evaporating, and being discharged. Through these ongoing processes, the material achieves drying within a very short period.
Suitable for materials
Suitable for the concentration, mixing, and drying of powdered, granular, and fibrous materials, as well as materials requiring low-temperature drying (such as biochemical products) in industries like chemicals, pharmaceuticals, and food. Particularly applicable for drying materials that are prone to oxidation, volatilization, heat sensitivity, strong irritation, toxicity, or those where crystal integrity must not be compromised.
Performance Features
◎ When heating oil, automatic constant temperature control is adopted to dry biochemical products.
◎ and mineral raw materials, temperature can range from 20 to 160^obetween C.
◎High thermal efficiency, more than double that of ordinary ovens.
◎ Indirect heating ensures that materials are not contaminated, meeting "GMP" requirements. The equipment is easy to maintain, operate, and clean.
◎ Recommended process arrangement: solvent recovery process arrangement.

Technical Specifications

Note: For materials whose volume changes significantly before and after drying, the loading coefficient may be appropriately increased or decreased.
