Introduction

Depth filter press is an enclosed filtration system designed for the special demands of the pharmaceutical industry.

1)Filtration process: Firstly, the liquid enters the filter press through the inlet, and the unfiltered liquid enters and completely fills the filter frame. Then, the filtered material liquid accumulates at the filtering layer, which occurs on the drainage profile of the filter plate to ensure uniform distribution of the filtered liquid, known as the formation of a filter cake precipitation layer.

2)Collect cake: A higher recovery rate is ensured by pressing the filter cake dry or cleaning it to the maximum extent possible. After filtration, the filter cake can be collected by opening the filter press.

3)CIP cleaning: For CIP cleaning, the entire filter press is sealed and all areas in contact with the material can be rinsed with the cleaning solution. In addition to the filter pad, other filter aids (such as diatomaceous earth) can be added or mixed into the product.

The filtration system is completely enclosed by circle O seal ring.
It can be CIP cleaned online, and compared to the strip shaped drainage profile, the convex point shaped drainage profile can significantly improve the drainage efficiency.
The suspension of filter medium on the product channel is our special design, Filter frame with different thicknesses can provide maximum flexibility in application, and the filter cake capacity and filter area can best meet the process requirements. There are no rough spots on the filter plate that can accommodate impurities, and the design meets GMP requirements to ensure that the filter press is easy to clean.
