Mechanical Foam Breakers For Fermenters And Washing Systems

Machines that break foam mechanically with centrifugal force, separating gas from liquid and returning the liquid to the tank instead of losing it over the top.

The Range

DP-F For Closed Tanks DP-K For Open Tanks

Both machines work the same way. The difference is where they mount: DP-F on a closed fermenter, DP-K over an open tank or pool.

Who Buys This Line

  • Yeast, amino acid and organic acid fermentation plants
  • Vinegar producers running aerated fermentation
  • Pulp and paper mills with foaming washing systems
  • Any process losing product as foam carryover

Problems It Solves

Product escapes as foam

Foam carrying liquid out of the vessel is lost product. Breaking the foam mechanically and returning the liquid cuts that loss.

Chemical defoamer contaminates the batch

A mechanical foam breaker uses centrifugal force rather than chemistry, so nothing is added to the fermentation.

Foam limits the working volume

When foam has to be allowed for, the vessel runs below its capacity. Controlling foam lets the batch size go back up.

Why This Line

How A Mechanical Foam Breaker Works

Centrifugal Separation

The machine uses centrifugal power to break foam during the fermentative process and separate liquid from gas.

Liquid Goes Back In

The separated foam liquid returns to the fermentation tank, which reduces the loss of escaped liquid.

Two Mountings

DP-F is applied to closed tanks, DP-K is designed for open tanks and pools.

Application Scenarios

Where Foam Breakers Are Fitted

Yeast And Amino Acid Fermentation

High aeration rates create persistent foam that has to be controlled without adding chemicals.

Vinegar Production

Aerated acetic fermentation where foam forms continuously through the batch.

Pulp And Paper Washing

Washing systems that foam heavily and carry liquid out of the circuit.

Industries Served By This Line

Selection Guide

Specifying A Foam Breaker

Closed Or Open Vessel

DP-F for a closed fermenter with a mounting nozzle, DP-K for an open tank or pool.

Describe The Foam

How fast it forms, how stable it is and how much aeration drives it. Stable protein foam needs more than a light foam.

Vessel Size And Nozzle

Tank volume, headspace height and the available mounting connection.

Materials And Cleaning

Stainless wetted parts and the cleaning regime the vessel already uses.

Answers

Defoaming Machines FAQ

Does the machine add anything to the product?

No. It breaks foam mechanically using centrifugal force, so no chemical defoamer enters the fermentation.

What happens to the liquid in the foam?

It is separated from the gas and returned to the fermentation tank, which is how the machine reduces the loss of escaped liquid.

Which version do I need?

DP-F is for closed tanks. DP-K is designed for open tanks and pools. The process vessel decides.

Which processes is it used in?

Fermentation for yeast raising, amino acids and vinegar, and washing systems in pulp and paper.

Can it replace a chemical defoamer completely?

That depends on how stable the foam is. Many plants use the machine to cut chemical dosing sharply rather than remove it entirely. Send the process detail and we will say what is realistic.
