Applications
Applications for pharmaceutical, food and chemical solid-liquid separation
Designed for filterable suspensions where controlled washing, dewatering, containment and automatic cake discharge are important to the process.
Food and ingredients
Salt, monosodium glutamate, starch, sugar, seasonings and food additives where hygienic solid-liquid separation is required.
Fine chemicals and new materials
Inorganic chemical products, pigments, dyes, resins, agrochemical intermediates and other difficult-to-filter solids.
Toxic or flammable feeds
Enclosed and protection-ready configurations can be engineered for hazardous or combustible suspensions after process-safety review.
Mineral and environmental processing
Mineral products and environmental solids where batch filtration, washing and low-moisture cake discharge are needed.
Working Principle
Controlled batch filtration from feed to bottom discharge.
A belt-driven motor brings the basket to operating speed. The programmed sequence controls feed distribution, centrifugal filtration, cake washing, final dewatering and hydraulic or pneumatic scraper discharge, while sensors and filter regeneration support repeatable batch operation.
Feed introduction
The suspension enters the rotating basket through a controlled distribution system that builds a stable filter cake.
Centrifugal filtration
Centrifugal force drives the liquid through the filter medium while solids remain on the basket wall.
Cake washing
Wash liquid is applied when required to displace mother liquor and improve product purity.
Final dewatering
The basket continues at the selected spin speed until the cake reaches the required residual-liquid target.
Scraper discharge
The basket slows to scraper speed and the actuated scraper removes the cake through the bottom outlet.
Filter-medium regeneration
Gas backwashing and scraper-roller action reduce retained cake and prepare the filter medium for the next cycle.
Performance Highlights
Stable, hygienic and automation-ready solid-liquid separation.
The vertical scraper centrifuge platform combines controlled filtration, washing, dewatering and cake handling with a contained structure that can be adapted to demanding industrial duties.
Automatic batch sequence
Feeding, filtration, washing, dewatering and scraper discharge are coordinated by the programmed operating cycle.
Enclosed hygienic containment
A sealed process chamber helps limit contamination and can be configured with nitrogen protection, CIP and explosion-protection measures.
Low-center-of-gravity structure
The compact layout supports stable running, flat-plate foundation-free installation and easier access for service work.
Hydraulic damping and stable operation
A hydraulic damping arrangement absorbs vibration and supports smoother operation across changing cake loads.
Filter-medium regeneration
Gas backwashing and scraper-roller action help reduce retained cake and restore filtration performance between batches.
DCS/HMI automation
Independent drive components, position detection and DCS/HMI interfaces support automatic sequencing and remote supervision.
System Configuration
Process protection and service options matched to the feed.
The equipment scope is selected around particle behavior, cake properties, hygiene requirements, utilities and the required level of automation.
Feed distribution and cake control
An inclined-plate distributor and controlled feed system help form a uniform cake; a level detector stops feeding at the programmed load.
Filtration and cake washing
Filter cloth or screen selection follows particle size, permeability and cake behavior, while the wash stage supports mother-liquor displacement.
Gas backwash and scraper assembly
Back-pulsing and scraper-roller action reduce residual solids and assist filter-medium regeneration before the next batch.
Sealing and process protection
The chamber, bearing housing, scraper area and feed path can use labyrinth and oil seals, nitrogen blanketing and explosion-protection provisions.
Controls, cleaning and maintenance
DCS/HMI control, independent drive components, CIP and project-specific contact materials support repeatable operation and maintainability.
