Three Phase Disc Stack Centrifuge for Milk Fat Removal
Description
Three Phase Disc Bowl Centrifuge for Milk Fat Removal is designed
for continuous separation of cream, skim milk, and fine impurities in dairy processing lines.
In milk processing, raw milk or pre-treated milk may contain fat
globules, water-based milk phase, fine suspended solids, and light
impurities.
A three phase disc bowl centrifuge uses high-speed centrifugal
force to separate milk fat from the heavier skim milk phase, while
removing a small amount of fine solids at the same time.
Typical Applications
- Milk fat removal
- Cream separation
- Skim milk production
- Milk standardization
- Raw milk clarification
- Dairy process liquid separation
- Whey cream recovery
- Fine impurity removal from milk
- Pretreatment before pasteurization or further processing
- Continuous dairy production lines
What It Separates in Milk Fat Removal
A three phase disc bowl centrifuge separates the milk stream into
different phases according to density difference.
| Output Phase | Typical Composition | Main Purpose |
|---|
| Cream Phase | Milk fat / cream-rich fraction | Recover or control milk fat content |
| Skim Milk Phase | Lower-fat milk liquid phase | Produce skim milk or standardized milk base |
| Fine Solids Phase | Fine impurities and suspended particles | Improve milk cleanliness and process stability |
The actual separation result depends on milk temperature, feed fat
content, flow rate, viscosity, solids content, and target fat
level.
Why Milk Fat Removal Needs Disc Bowl Centrifugation
Milk fat globules are much smaller and lighter than the water-based
milk phase. Simple settling is too slow and unstable for industrial
dairy production.
A disc bowl centrifuge provides a compact high-speed separation
field, allowing cream and skim milk to separate continuously.
If milk fat separation is not controlled well, the dairy plant may
face:
- Unstable cream concentration
- Inconsistent skim milk fat content
- Higher load on downstream standardization
- More impurities entering pasteurization or processing sections
- Lower process consistency
- More frequent quality adjustment
How the Three Phase Disc Stack Centrifuge Works
Milk enters the high-speed 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 phase moves toward the center.
- The heavier skim milk phase moves outward.
- Fine impurities and suspended solids move toward the outer area of
the bowl.
The separated cream and skim milk phases are discharged through
different outlets. Fine solids are collected or discharged
depending on the machine design.

Main Advantages in Milk Fat Removal
Efficient Milk Fat Separation
The centrifuge separates cream from skim milk continuously and
supports stable milk fat control.
Better Skim Milk Quality
It helps reduce residual fat and fine impurities in the skim milk
phase, depending on feed and operating conditions.
Continuous Dairy Processing
The machine supports continuous feeding, separation, and discharge,
making it suitable for dairy production lines.
Compact High-Speed Separation
Disc bowl structure provides high separation efficiency in a
compact footprint.
Supports Milk Standardization
Separated cream and skim milk can be recombined or adjusted to meet
target fat levels.
CIP-Friendly Design
The machine can be configured for cleaning-in-place, supporting
dairy hygiene and reducing manual cleaning workload.
Expected Results
Under suitable feed and operating conditions, the system can
typically help achieve:
- 80–98% milk fat separation efficiency
- 0.03–0.10% residual fat in skim milk
- 20–45% cream fat concentration
- 50–90% reduction of fine suspended impurities
- 8–24 hours/day continuous operation
Final performance depends on milk temperature, feed fat content,
flow rate, viscosity, solids load, bowl speed, and process control
settings.
What Data Is Needed for Selection?
To recommend a suitable three phase disc bowl centrifuge for milk
fat removal, please provide:
- Feed material: raw milk, preheated milk, whey stream, or dairy
liquid
- Processing capacity, in L/h or m³/h
- Feed fat content
- Target skim milk fat content
- Target cream concentration
- Feed temperature
- Solids or impurity content
- Viscosity, if available
- 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
FAQ
What is this centrifuge used for?
It is used to separate cream, skim milk, and fine impurities from
milk or dairy liquid streams.
Can it produce skim milk?
Yes. It can remove most milk fat from the feed and produce a
lower-fat skim milk phase.
Can it control cream concentration?
Yes. Cream concentration can be adjusted within a certain range by
controlling operating parameters and outlet conditions.
Is CIP cleaning available?
Yes. For dairy applications, CIP cleaning design is usually
recommended to support hygiene and reduce manual cleaning.
Can it be used before pasteurization?
It can be used before or after heating depending on the dairy
process design. The final arrangement should be confirmed according
to the plant process.
