Agitated pressure filter and vacuum dryer for solid-liquid separation

2023/04/22

Agitated filter press dryer is a high-quality equipment designed for solid-liquid separation process in pharmaceutical, chemical, fine chemical and food industries, through pressure and vacuum drying for filtration.

In filtration applications, some products are more desirable to be handled in a hermetically sealed manner during their manufacture due to their particular hazardous or toxic properties, or simply to prevent cross-contamination. Wuxi ZhangHua agitated filter press dryers have been specifically designed to meet these needs, ensuring a pure substance free from contaminating elements.


Wuxi ZhangHua Agitated Filter Press Dryer is designed according to GMP and EHEDG standards, suitable for all types of pharmaceutical and fine chemical applications. Our machines are effective in aseptic applications, and we have special designs for installation in clean rooms.
