Mechanical Foam Breaker Applications — 17 Industries
The DP Series mechanical foam breaker replaces chemical defoamers wherever stable foam costs product, time or yield. Pick your process below — each application page shows how the unit is mounted and sized for that industry.
Food & beverage foam control
Soymilk foam control
Soymilk foams heavily during boiling, homogenising and tank storage — the protein-rich foam overflows, carries product away and traps air in filling lines. Chemical defoamers leave residue in a product consumers expect to be clean.
View application
Coffee extraction foam control
Extraction tanks, holding vessels and instant-coffee lines foam as dissolved gases and saponins escape the brew. Foam carries aroma and solids out of the process and makes level control unreliable — and chemical defoamers can be tasted in the cup.
View applicationFermentation foam control
Vinegar brewing foam control
Acetic acid fermentation generates strong surface foam as aeration and metabolic gases rise through the mash. If it escapes the fermenter, you lose product, acid and process time — and chemical defoamers can interfere with the acetobacter culture itself.

Soy sauce brewing foam control
Moromi (soy sauce mash) fermentation produces thick foam as yeast and enzymes work through the mash. Foam overflow loses product, disturbs fermentation and can carry spoilage organisms — and chemical defoamers risk affecting the delicate flavour balance.

FGD desulfurization foam control
Flue-gas desulfurization systems build up foam in the limestone slurry — driven by organic carry-over from the flue gas and process additives. Foam pushes slurry out, upsets level control and can drop desulfurization efficiency when reagent is wasted.

Coal washing foam control
Washing water, flotation and settling circuits in coal preparation generate foam that carries fine coal away and slows water recovery. Chemical defoamers add cost and can interfere with the same process chemistry you depend on.

Paper making foam control
Pulp suspensions, white water and coating kitchens all foam — and the bubbles travel into the sheet. Foam causes pinholes, breaks and fibre loss, while chemical defoamers can upset retention and sizing chemistry.
View application
Textile process foam control
Dyeing, desizing, mercerising and finishing baths foam from surfactants and processing aids. Foam causes uneven dyeing, fabric marking and lost chemicals — and defoamers can leave residue that affects hand feel and subsequent finishing.

Lithium battery recycling foam control
Leaching, precipitation and washing steps in battery recycling generate foam as gases evolve from reacting slurries. Foam carries metal-bearing liquor out of the tank and can create overflow safety hazards — chemical defoamers add cost and risk contaminating the recovered salts.
View application
Electroplating foam control
Electroplating baths foam from wetting agents, brighteners and the hydrogen evolved at the electrodes. Foam can carry bath liquor over the tank edge, leave pinholes in the deposit and unbalance the bath chemistry.

Flotation cell foam control
In mineral flotation, controlled froth is part of the process — but unstable, surging foam overflows the cell lip, spills concentrate and upsets the pulp level that operators work hard to stabilise. Chemical defoamers attack the same froth you rely on.
