Defoaming Machines
Defoaming Machine
DP series mechanical defoamer for open and closed vessels.

Foam Breaker
The foam breaker build of the DP series, separating gas from liquid so the batch stays in the tank.
Overview
What This Pump Does
The DP series foam breaker is a mechanical defoaming machine used mainly in fermentation processes for yeast raising, amino acid production and vinegar, and in pulp and paper washing systems.
It uses centrifugal power to break foam and separate liquid from gas during fermentation. DP-F is applied to closed tanks and DP-K is designed for open tanks or pools.
- DP series mechanical foam breaker
- Centrifugal foam breaking action
- Gas and liquid separation with liquid return
- DP-F for closed tanks
Key Benefits
Keeping The Batch In The Vessel
Mechanical Not Chemical
Foam is broken by centrifugal action, so the fermentation chemistry is untouched.
Recovers The Liquid
Separated liquid returns to the tank, reducing the loss that foam carryover causes.
Closed Or Open Vessels
DP-F mounts on closed tanks, DP-K works on open tanks and pools.
Continuous Operation
The machine works through the batch rather than being started when foam is already out of control.
Application Scenarios
Where It Is Installed
Closed Fermenters
DP-F mounted on a closed vessel with controlled headspace.
Open Tanks And Pools
DP-K arranged above an open vessel where foam builds on the surface.
Mill Washing Circuits
Pulp and paper washing systems with persistent foam.
Who It Is For
- Fermentation and biotechnology plants
- Vinegar and food acid producers
- Pulp and paper mills
- Plants reducing defoamer chemical costs
Problems It Solves
Foam escapes the vessel
Breaking the foam mechanically stops carryover before it leaves the tank.
Chemistry changes the product
No chemical is added, so the fermentation and the downstream process stay as designed.
Lost liquid is lost yield
Returning separated liquid to the tank recovers what would otherwise be waste.

Compared With Other Options
| Defoaming machine | The same DP series principle. Which name appears on the quotation depends on the version and the vessel. |
|---|---|
| Antifoam dosing | Dosing adds a chemical that may need removing later. Mechanical breaking does not. |
Use Guide
Setting Up A Foam Breaker
Confirm Vessel Type
Closed tank means DP-F, open tank or pool means DP-K.
Measure Headspace
The machine needs working space above the liquid at maximum fill.
Arrange The Return
Make sure separated liquid drains back into the vessel cleanly.
Tune During Fermentation
Commission during a live batch, as foam behaviour changes through the cycle.
Answers
Foam Breaker FAQ
How is it different from the defoaming machine listing?
It is the same DP series equipment. The version, DP-F or DP-K, is chosen by the vessel.
Does it add anything to the fermentation?
No. It breaks foam mechanically using centrifugal power.
Where does the liquid go?
Back into the fermentation tank, which reduces the loss of escaped liquid.
Can it be used outside fermentation?
Yes, it is also used in pulp and paper washing systems.
What do you need to quote one?
Vessel type and volume, headspace, the process and how the foam behaves.
