Three Phase Disc Stack Centrifuge for Milk Processing
Description
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.
Typical Applications
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
What It Controls in Milk Processing
A three phase disc stack centrifuge helps clarify low-solids dairy
liquids and control different fractions according to density
difference.
| Separation Target | Typical Composition | Main Purpose |
|---|
| Clarified Dairy Liquid | Milk, whey, or low-solids dairy liquid after clarification | Provide a cleaner and more stable liquid stream for downstream
processing |
| Light Fat-Rich Fraction | Small amount of cream or fat-rich phase, depending on process
target | Support fat adjustment or reduce fat fluctuation when required |
| Fine Impurities | Sediment, fine suspended solids, protein particles, and process
residues | Reduce impurity load and protect downstream equipment |
The actual separation result depends on milk type, feed
temperature, flow rate, fat content, solids load, viscosity, and
downstream process requirements.
How the Three Phase Disc Stack Centrifuge Works
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.

Main Advantages in Milk Processing
Wider Dairy Process Use
The machine can support cream separation, milk clarification, skim
milk production, whey cream recovery, and dairy liquid
pretreatment.
Fine Clarification Performance
The disc stack structure helps remove fine suspended impurities
from low-solids dairy liquids.
Stable Milk Standardization Support
Separated cream and skim milk phases can be used for fat adjustment
and process control.
Continuous Operation
The centrifuge supports continuous feeding, separation, and liquid
discharge in dairy production lines.
Compact High-Speed Separation
Compared with settling or coarse filtration, disc stack
centrifugation provides faster and finer separation in a compact
footprint.
Hygienic Processing Design
Food-contact materials and CIP-friendly design help meet dairy
production cleaning requirements.
Expected Results
- 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.

FAQ
What is a three phase disc stack centrifuge used for in milk
processing?
It is used for continuous cream separation, skim milk
clarification, fine impurity removal, and dairy liquid process
stabilization.
Is this suitable for high-solids dairy slurry?
No. Disc stack centrifuges are suitable for low-solids dairy
liquids. High-solids slurry or thick residue should be handled by
other equipment.
Can it support milk standardization?
Yes. By separating cream and skim milk phases, it can support
downstream fat adjustment and milk standardization.
Can it remove fine impurities?
Yes. It can remove part of the fine suspended impurities, depending
on feed condition and machine configuration.
Is CIP cleaning available?
Yes. CIP design is recommended for dairy processing to support
hygiene and reduce manual cleaning.
