Applications
Automatic Bag-Inverting Filtration Centrifuge: industrial applications
Applications include pharmaceutical production and fine chemicals. Confirm material properties and process conditions before selecting the equipment configuration.
Fine chemicals
Difficult-to-filter or high-value chemical products where thin-cake processing and high recovery are economically important.
Food and ingredients
Food-process suspensions requiring enclosed center feeding, hygienic cleaning and controlled cake washing.
Recovery-critical products
Applications where conventional automatic horizontal centrifuges leave unacceptable cake residue on the filter medium.
Working Principle
From feed preparation to finished product.
The process route is selected around the material and product targets.
Sealed center feeding
With the basket rotating at low to medium speed, feed enters through the center pipe and is distributed evenly across the filter-bag surface.
Centrifugal filtration
The liquid phase passes through the filter cloth, screen slots and basket perforations to the filtrate outlet, while solids form an annular cake.
Cake washing
After feeding, the basket accelerates for initial dewatering. Wash liquid can then be introduced through the feed line according to the process recipe.
Final dewatering
A second high-speed stage removes additional liquid and brings the washed cake to the specified residual-moisture target.
Bag-inverting discharge
At discharge speed, the push plate travels outward and turns the filter bag inside out. The cake separates from the cloth and exits under centrifugal force and gravity.
Bag reset
After discharge, the filter bag returns to its operating position and the centrifuge is ready for the next automatic cycle.
Performance Highlights
Process performance shaped around the product.
Final performance remains dependent on feed properties and engineering confirmation.
Complete cake recovery
Outward filter-bag inversion releases the cake across the full cloth surface, minimizing residue and improving product yield.
No cake compaction during scraping
The non-scraping discharge principle helps prevent hard cake buildup and preserves easy product release.
Efficient thin-cake filtration
The operating range is selected for the material and confirmed for the quoted configuration.
Online cloth regeneration
In-machine soaking and reslurry washing reduce manual cloth removal and maintain stable long-term filtration performance.
Hygienic contained design
Through-wall installation, enclosed center feeding and a compact process chamber support clean production and lower inert-gas demand.
Repeatable automatic cycles
Precise automation reduces manual intervention and improves consistency between production batches.
Comprehensive cleanability
CIP, soak cleaning and sanitization options support GMP-oriented pharmaceutical and food applications.
Accessible maintenance
The full-opening cover exposes internal components for cleaning, inspection and service.
System Configuration
Standard process path with project-specific options.
Core equipment and auxiliary systems are selected around the process duty.
Bag-inverting discharge mechanism
The axial push plate turns the filter bag outward so the cake separates across the complete cloth surface without conventional scraping.
Thin-cake operation
The operating range is selected for the material and confirmed for the quoted configuration.
Online filter-bag regeneration
The bag can be soaked and reslurried inside the centrifuge for in-place cleaning and recovery of filtration performance.
Through-wall installation
Optional through-wall layout can separate the drive and auxiliary zone from the clean production area.
Compact enclosed chamber
Fully enclosed construction and a small process-space volume reduce external contamination centrifuge, cross-contamination potential and protective-gas consumption.
Cleaning and sanitation
CIP, soaking, rinsing and sanitization functions can be configured for pharmaceutical, food and other high-hygiene duties.
Automatic control
The control system sequences feeding, filtration, washing, dewatering, inversion discharge and bag reset for repeatable batches.
Full-opening cover
The fully opening door provides access for inspection, cleaning and routine maintenance.
