Applications
Hygienic Through-Wall Horizontal Scraper Filtration Centrifuge: industrial applications
Applications include pharmaceuticals and intermediates and food processing. Confirm material properties and process conditions before selecting the equipment configuration.
Food processing
Low-viscosity food and ingredient suspensions requiring cleanable product-contact surfaces and controlled batch operation.
Fine chemicals
High-value chemical products requiring low cake moisture, effective washing and separation from the mechanical drive area.
Hazardous media
Selected toxic, harmful, flammable or explosive suspensions after material compatibility review and project-specific hazardous-area engineering.
Working Principle
From feed preparation to finished product.
The process route is selected around the material and product targets.
Inerting and acceleration
Purge the enclosed process chamber with nitrogen or another approved inert gas. Once the permissive conditions are satisfied, the machine accelerates automatically.
Automatic feeding
At feed speed, the inlet valve opens and cake-level detection starts. Liquid passes through the filter medium and basket perforations while solids form a cake inside the basket.
Cake-depth control
When the preset cake thickness is reached, the level controller closes the feed valve to prevent overfilling and maintain repeatable batch loading.
Cake washing
The centrifuge adjusts to the programmed washing speed and opens the wash valve until the specified wash volume has been delivered.
Final dewatering
After washing, the basket accelerates to the selected dewatering speed until the required cake-moisture target is achieved.
Scraper and screw discharge
At discharge speed, the scraper progressively enters the cake and transfers solids into the screw-conveyor hopper. The screw removes the product, the scraper retracts and the next cycle can begin.
Performance Highlights
Process performance shaped around the product.
Final performance remains dependent on feed properties and engineering confirmation.
Through-wall hygienic layout
Physical separation of the drive zone and production zone reduces the risk of mechanical contaminants entering the clean room.
Fully automatic batch cycle
PLC sequencing coordinates inerting, acceleration, feeding, washing, dewatering, scraper discharge and return to the next cycle.
Comprehensive safety protection
Multiple mechanical, electrical and hydraulic interlocks monitor speed, vibration, cover position, motor load, scraper position, bearings and lubrication.
Contained explosion protection
Positive-pressure inerting, optional online oxygen monitoring and fully enclosed construction support suitably engineered flammable or explosive duties.
CIP cleanability
Strategically positioned spray devices provide multi-directional internal washing and help minimize hygienic dead zones and cross-contamination risk.
Optional sterile processing
Steam-sterilization components can be added for SIP and sterile-product applications.
Flexible low-energy operation
Stepless VFD speed control matches each process stage, while regenerative braking can recover energy where appropriate.
GMP-oriented engineering
The hygienic architecture is intended for validated facilities working toward GMP and applicable FDA, COS or TGA expectations; final compliance depends on the complete project and qualification scope.
System Configuration
Standard process path with project-specific options.
Core equipment and auxiliary systems are selected around the process duty.
Through-wall segregation
The process housing faces the clean production room while the drive and service components remain in the technical area, reducing contamination transfer from mechanical systems.
Nitrogen and oxygen monitoring
Automatic inert-gas pressure monitoring and optional online oxygen analysis help maintain the enclosed process chamber within the approved operating envelope.
CIP coverage
Multiple spray balls and directional nozzles can wash the basket, chamber and product-contact areas in place while reducing inaccessible hygienic zones.
SIP capability
Optional steam-sterilization components support sanitization or SIP cycles for sterile API and other high-hygiene applications.
Multi-layer safety interlocks
Speed, vibration, cover-open, motor overload, hydraulic cover lock, scraper position, main-bearing temperature and lubrication protection can be integrated into the control system.
Energy-efficient drive
VFD control provides stepless recipe speeds, with dynamic or regenerative braking selected according to the project.
Automatic cake discharge
The controlled scraper cuts the cake into the screw-conveyor hopper for enclosed, repeatable solids removal.
