Bag Lifting Centrifuge is a batch-type top discharge separation system designed for high-purity, heat-sensitive and contamination-sensitive materials.
It is widely used in antibiotic intermediate separation, where strict cleanliness, low residue, and crystal integrity are required.
The lifting bag discharge system allows gentle cake removal without mechanical scraping, reducing crystal damage and ensuring consistent product quality in pharmaceutical production.
This equipment is specially designed for pharmaceutical and fine chemical batch processes, including:
Antibiotic intermediates typically present the following challenges:
Conventional discharge systems often cause:
Our Bag Lifting Centrifuge provides a gentle and controlled batch separation solution:
The filter bag lifting design ensures no scraping damage, protecting fragile antibiotic crystals.
Optimized basket structure improves mother liquor removal efficiency, reducing residual moisture.
Each cycle is fully controllable:
Filter Cloth Installation → Slurry Feeding → Gentle Basket Filtration → Crystal Cake Formation → Optional Washing → Controlled Dewatering → Bag Lifting Discharge → Collection → Cleaning
During operation, antibiotic intermediate slurry is fed into the rotating basket under closed conditions.
Under centrifugal force, solvent passes through the filter medium while sensitive antibiotic crystals are retained and gently formed into cake, avoiding excessive shear or breakage.
After optional washing and final dewatering, the bag lifting system enables soft discharge, ensuring minimal crystal damage and maintaining high product purity suitable for pharmaceutical applications.
