In the production processes of pharmaceutical intermediates, fine chemicals, new materials, new energy, and electronic chemicals, certain materials exhibit strong corrosiveness while demanding high product purity, residual solvent levels, moisture content, and controlled production environments. Traditional filtration, washing, and drying processes typically require multiple pieces of equipment, involving repeated material transfers between units. This not only complicates the production flow but may also lead to material loss, cross-contamination, and leakage of corrosive media.

To meet the production requirements for highly corrosive materials, Jiangsu Bohong, with over 10 years of experience in drying equipment manufacturing, specializes in producing vacuum drying equipment made from specialty materials. Based on the specific corrosiveness and process conditions of different materials, we design and manufacture equipment using materials such as Hastelloy, titanium, 2507, and 2205.

Jiangsu Bohong offers professional solutions including Hastelloy drum-cone filter-wash-dryers, specialty-material drum-cone three-in-one units, Hastelloy single-cone vacuum dryers, C276 Hastelloy paddle vacuum dryers, titanium vacuum dryers, and drying equipment made from 2507 and 2205 duplex stainless steel—providing integrated filtration, washing, and drying solutions for challenging corrosive conditions.

I. What are the advantages of the Hastelloy drum-cone filter-wash-dryer?

Closed-Loop Production  
Filtration, washing, and drying are all completed within a single unit, minimizing material exposure to the external environment. This is particularly beneficial for toxic, irritating, corrosive, or organically solvent-containing materials, significantly improving process sealing.

Reduced Material Transfer  
Traditional methods require separate filtration, washing, and drying equipment, necessitating multiple material transfers. By using an integrated three-in-one system, intermediate transfer steps are eliminated.

Lower Risk of Cross-Contamination  
For pharmaceutical intermediates, electronic chemicals, and high-purity new materials, reducing material handling helps minimize the risk of external contaminants entering the final product.

Vacuum Low-Temperature Drying  
The vacuum system reduces internal pressure, enabling drying at relatively low temperatures. For heat-sensitive products, the drying process can be optimized by controlling vacuum level, heating temperature, and agitation speed.

Corrosion-Resistant Material Design  
Depending on the corrosiveness of the material, equipment components—including the cylinder, cone, filtration system, agitator shaft, impeller, and other parts in contact with the material—can be constructed from Hastelloy, titanium, 2507, 2205, or other suitable materials.

II. Which industries benefit from the Hastelloy drum-cone three-in-one equipment?

Pharmaceutical Intermediates  
Pharmaceutical intermediate production typically involves reaction, crystallization, filtration, washing, and drying. For intermediates that are corrosive and require high product purity, specialty drum-cone filter-wash-dryers are ideal.

Fine Chemicals  
Fine chemical products vary widely, and some processes involve acids, alkalis, chlorides, and organic solvents. Equipment can be customized with Hastelloy, titanium, 2507, or 2205 based on material corrosiveness and drying requirements.

Pesticides and Pesticide Intermediates  
The production of pesticide active ingredients and intermediates often includes crystallization, filtration, washing, and drying. Using a closed-loop three-in-one system minimizes material transfer and improves efficiency.

New Materials  
Certain new materials demand strict control over purity, moisture content, and residual solvents. Integrated filtration, washing, and vacuum drying reduce intermediate transfers and help ensure consistent product quality.

New Energy and Electronic Chemicals  
Production in new energy and electronic chemical sectors requires stringent control over impurity ions, metal contamination, and product purity. Equipment can be designed using titanium, Hastelloy, 2507, or 2205 depending on specific process needs.
