Overview of Antioxidant Dryer:
The SZG double-cone vacuum dryer is a new generation drying device developed by our factory, integrating similar domestic technologies. The SZG double-cone vacuum dryer features a two-stage elastic connection method using belts and chains, ensuring stable operation. The specially designed tooling fully reflects the excellent concentricity of the two shafts, and both the heat transfer medium and vacuum systems utilize reliable American technology rotary joints. Building on this, we have developed the SZG-A, which offers both stepless speed regulation and constant temperature control. As a professional manufacturer of drying equipment, we serve users with over a hundred units annually. Our products cover a full range of heat transfer media, from high-temperature thermal oil to medium-temperature steam and low-temperature hot water. When drying sticky materials, we will specially design a "scraper plate" mechanism or install rollers inside the tank for you.

Principle of Antioxidant Dryer:
● Introduce a heat source (such as hot water, low-pressure steam, or thermal oil) into the sealed interlayer, and the heat is transferred to the material being dried through the inner shell.
● Driven by power, the tank rotates slowly, and the materials inside are continuously mixed, thereby achieving enhanced drying.
● The material is in a vacuum state, where the reduced vapor pressure causes the moisture (solvent) on the material's surface 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 permeates to the surface, evaporates, and is discharged. These three processes occur repeatedly, allowing the material to achieve drying within a very short period.
Features:
● When the oil is heated, automatic constant temperature control is adopted, which can dry biochemical products and mineral raw materials, with the temperature ranging from 20 to 160°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.
Application:
Suitable for the concentration, mixing, and drying of powdery, granular, and fibrous materials in industries such as chemical, pharmaceutical, and food processing, as well as materials requiring low-temperature drying (e.g., biochemical products). It is especially applicable for drying materials that are prone to oxidation, volatilization, heat sensitivity, strong irritation, toxicity, or those where crystal integrity must not be compromised.
