| Product List |
The Decanter Centrifuge for Lactic Acid Separation is designed for continuous solid-liquid separation in lactic acid fermentation and purification processes.
It is suitable for separating fermentation broth solids, bacterial cells, biomass residues, calcium lactate slurry, and other suspended solids generated during lactic acid production.
The centrifuge provides continuous clarification, solids concentration, and liquid recovery, helping improve downstream filtration efficiency, reduce product loss, and support stable industrial-scale lactic acid processing.
Fermentation broth contains microorganisms and fine suspended solids that are difficult to settle naturally.
Biomass particles often have small size and low settling speed.
Lactic acid remains in the liquid phase, while solid residues may retain valuable liquid.
Industrial fermentation plants require stable operation with minimal downtime.
Acidic liquids and fermentation chemicals may affect equipment materials.
Typical Process Flow:
Lactic Acid Fermentation Broth
→ Feed Tank
→ Optional Flocculant Dosing
→ Decanter Centrifuge
→ Clarified Lactic Acid Liquid + Concentrated Biomass Solids
Clarified Liquid → Purification / Concentration / Refining
Separated Solids → Further Treatment / Disposal / Recovery
Lactic acid fermentation broth enters the rotating bowl through the feed inlet.
Under centrifugal force, biomass and suspended particles move toward the bowl wall.
Separated lactic acid liquid remains in the inner liquid zone and flows toward the clarified liquid outlet.
The scroll continuously transports concentrated biomass solids toward the discharge end.
Clarified liquid and dewatered solids are discharged continuously for downstream processing.

Handles large-volume fermentation liquids without batch filtration cycles.
Reduces valuable lactic acid loss by improving solid-liquid separation efficiency.
Suitable for microbial cells and fine fermentation residues.
Stainless steel contact parts and cleanable structure support food and bio-based applications.
Adjustable operating parameters allow adaptation to different fermentation conditions.
Please provide:
Yes. It is commonly used for separating biomass, fermentation residues, and suspended solids from lactic acid production liquids.
Proper selection of centrifugal force and operating parameters helps maximize liquid recovery and reduce product loss.
Not always. It depends on biomass concentration, particle size, and required liquid clarity.
Stainless steel configurations such as SS304 or SS316L can be selected according to corrosion requirements.
Yes. The decanter centrifuge is designed for continuous feeding, separation, and solids discharge.
Peony welcomes distributor and agent cooperation with lactic acid producers, fermentation plants, biotechnology companies, food ingredient manufacturers, and industrial separation partners.
