Three Phase Disc Stack Centrifuge for Milk Processing

Three Phase Disc Stack Centrifuge for Milk Processing is designed for continuous separation and clarification of low-solids dairy liquids.

In dairy processing, milk streams may contain milk fat, skim milk phase, fine suspended impurities, protein particles, and process residues.

The disc stack centrifuge uses high-speed centrifugal force and a compact disc stack structure to separate different phases efficiently and support stable dairy production.

This centrifuge is suitable for general dairy liquid clarification and process stabilization in milk processing lines.

• Raw milk clarification before heat treatment
• Removal of sediment and fine suspended impurities
• Dairy liquid polishing before pasteurization or UHT processing
• Clarification of preheated milk streams
• Whey liquid clarification before concentration or evaporation
• Reduction of fine solids entering downstream equipment
• Protection of heat exchangers, filters, and separators
• Process support for milk standardization lines
• Low-solids dairy liquid separation
• Continuous hygienic dairy processing systems

The milk stream enters the rotating bowl through the feed system.

Inside the bowl, a stack of conical discs creates many thin separation layers. Under centrifugal force:

• The lighter cream or fat-rich phase moves closer to the center.
• The heavier skim milk or low-fat liquid phase moves outward.
• Fine suspended impurities and heavier particles move to the outer area of the bowl.

The separated liquid phases are discharged through different outlets. Fine solids are retained or discharged according to the machine design.

The machine can support cream separation, milk clarification, skim milk production, whey cream recovery, and dairy liquid pretreatment.

The disc stack structure helps remove fine suspended impurities from low-solids dairy liquids.

Separated cream and skim milk phases can be used for fat adjustment and process control.

The centrifuge supports continuous feeding, separation, and liquid discharge in dairy production lines.

Compared with settling or coarse filtration, disc stack centrifugation provides faster and finer separation in a compact footprint.

Food-contact materials and CIP-friendly design help meet dairy production cleaning requirements.

• 50–90% reduction of fine suspended impurities
• 30–70% reduction of sediment and process residues before downstream heat treatment.
• Lower impurity load before pasteurization, UHT, concentration, or evaporation.
• Reduced risk of fouling in heat exchangers, filters, and pipelines.
• More stable dairy liquid quality for continuous processing.
• 8–24 hours/day continuous operation

Final performance depends on milk type, feed temperature, flow rate, solids load, viscosity, bowl speed, and process control settings.

To recommend a suitable disc stack centrifuge for milk processing, please provide:

• Feed material: raw milk, preheated milk, whey, cream-containing stream, or skim milk stream
• Processing capacity, in L/h or m³/h
• Feed fat content
• Target cream concentration
• Target skim milk fat content
• Feed temperature
• Solids or impurity content
• Required clarification effect
• Required sanitary standard
• CIP cleaning requirement
• Continuous operating hours per day
• Existing process position
• Site voltage and control preference
• Need for skid-mounted system or not

It is used for continuous cream separation, skim milk clarification, fine impurity removal, and dairy liquid process stabilization.

No. Disc stack centrifuges are suitable for low-solids dairy liquids. High-solids slurry or thick residue should be handled by other equipment.

Yes. By separating cream and skim milk phases, it can support downstream fat adjustment and milk standardization.

Yes. It can remove part of the fine suspended impurities, depending on feed condition and machine configuration.

Yes. CIP design is recommended for dairy processing to support hygiene and reduce manual cleaning.
