Fermentation and biotechnology
Fermentation broths, yeast suspensions, protein liquids and ultrafiltration retentates requiring continuous concentration or clarification.
Double-cone screw sedimentation
Double-Cone Horizontal Decanter Centrifuge
High-speed continuous clarification, concentration and dewatering in a purpose-designed double-cone solid bowl. Designed and manufactured for fermentation and biotechnology and starch and food processing. Review the working principle, performance features and available configuration details below when specifying your industrial project.
- Special double-cone geometry performs primary concentration and intensified dewatering in one continuous machine.
- High-speed sedimentation handles fine, soft and difficult-to-settle materials while the scroll processes higher-solids feeds continuously.
- Adjustable differential speed and online pond-depth control balance clarification, solids concentration, cake compaction and residual moisture.

Applications
Double-Cone Horizontal Decanter Centrifuge: industrial applications
Applications include fermentation and biotechnology and starch and food processing. Confirm material properties and process conditions before selecting the equipment configuration.
Starch and food processing
Starch-process streams, beer and protein liquids, fruit-juice by-products and related food-process suspensions.
Plant extraction
Plant extracts and botanical process liquors requiring continuous solids removal, concentration or clarification.
Fine processing
Soft solids and fine-particle suspensions where both clarification quality and concentrated-solids dewatering are important.
Working Principle
From feed preparation to finished product.
The process route is selected around the material and product targets.
Feed and primary separation
Suspension enters through the feed pipe and is introduced near the end of the small-angle scroll into the high-speed double-cone bowl.
Concentration zone
In the increasing-diameter cone, centrifugal force settles the solid phase while the scroll conveys the concentrated material toward the bowl's maximum-diameter section.
Deep-dewatering zone
The solids then enter the large-angle cone. As bowl diameter decreases, centrifugal loading and scroll transport continue to remove liquid from the concentrated solids.
Continuous solids discharge
Dewatered solids are conveyed to the discharge ports at the end of the large-angle cone and leave the machine continuously.
Pressurized liquid discharge
Clarified liquid flows into the clarification zone and is discharged under pressure through an adjustable liquid-discharge impeller, or paring disc.
Performance Highlights
Process performance shaped around the product.
Final performance remains dependent on feed properties and engineering confirmation.
Two-stage double-cone separation
The first cone concentrates the solids and the second cone intensifies dewatering in one continuous rotating assembly.
High separation intensity
The operating range is selected for the material and confirmed for the quoted configuration.
Fine-particle capability
High-speed sedimentation improves separation of fine, soft and comparatively difficult-to-settle solids.
Continuous high-solids processing
Continuous feeding, settling, concentration, dewatering and solids discharge support large-scale production.
Online pond-depth control
The adjustable liquid-discharge impeller changes the liquid level during operation to tune clarification and cake moisture.
Flexible process optimization
Bowl speed, differential speed and liquid level can be coordinated for different feed properties and product-quality targets.
Improved clarification
High centrifugal intensity and controllable residence conditions support clear liquid discharge on suitable feeds.
Integrated concentration and dewatering
Combining both functions in one machine reduces intermediate handling and simplifies the continuous process route.
System Configuration
Standard process path with project-specific options.
Core equipment and auxiliary systems are selected around the process duty.
Double-cone rotating assembly
The increasing-diameter concentration cone and decreasing-diameter dewatering cone complete two separation stages in one continuous machine.
Differential-speed scroll
The bowl and scroll rotate in the same direction with a controlled speed difference that governs solids residence time, conveying rate and cake dryness.
Adjustable pond depth
The liquid level can be changed online through the variable liquid-discharge impeller to optimize clarification, solids concentration, cake compaction and residual moisture.
Pressurized liquid outlet
The paring-disc arrangement removes clarified liquid under pressure and can reduce the need for a separate discharge pump, subject to process design.
Continuous phase discharge
The scroll continuously conveys settled solids to the discharge end while clarified liquid leaves through a separate outlet.
Duty-specific protection
Wear protection, sealing, drive control and condition monitoring are selected for the actual feed and operating environment.
