Dencanter Centrifuge for Casein Milk Separation
Description
The Decanter Centrifuge for Casein Milk Separation is designed for continuous separation of casein solids from milk or dairy fermentation streams.
It is suitable for casein production, dairy protein recovery, milk processing, and whey treatment applications. The centrifuge uses high centrifugal force to separate fine protein particles from liquid, improving solid recovery and reducing moisture content.
For casein processing, the main challenges include fine protein particles, high moisture content, sticky solids, and strict hygiene requirements. The decanter centrifuge provides continuous operation, stable separation performance, and sanitary processing for dairy plants.
Typical Applications
- Casein curd dewatering
- Milk protein recovery
- Acid casein production
- Rennet casein processing
- Dairy fermentation residue separation
- Whey protein solid recovery
- Dairy wastewater treatment
- Protein slurry concentration
Casein Milk Separation Challenges
Fine Casein Particle Separation
Casein particles are extremely fine and difficult to separate by gravity settling, which may cause protein loss and reduced recovery efficiency.
High Moisture Content in Casein Cake
Fresh casein curd contains high retained moisture, increasing drying time and energy consumption during downstream processing.
Sticky and Compressible Casein Solids
Casein solids can form sticky cakes with poor flowability, making conveying, discharge, and further handling more difficult.
Protein Loss During Separation
Fine protein particles may remain suspended in liquid, affecting product yield and increasing valuable material loss.
Strict Dairy Hygiene Requirements
Dairy production requires clean processing conditions to prevent contamination and meet food-grade standards.
Variable Casein Slurry Conditions
Feed concentration, particle size, and slurry properties can change depending on milk source and production process.

How the Decanter Centrifuge Works
1. Casein Slurry Feeding
Milk-based casein slurry enters the rotating bowl through the feed system.
2. Solid Sedimentation
Under centrifugal force, casein particles move toward the bowl wall and form a concentrated solids layer.
3. Liquid Clarification
Separated liquid moves toward the inner liquid zone and exits through the liquid discharge area.
4. Solids Conveying
The scroll continuously transports concentrated casein solids toward the discharge end.
5. Continuous Discharge
Dewatered casein cake and clarified liquid are continuously discharged for further processing.

FAQ
Can the decanter centrifuge separate fine casein particles?
Yes. High centrifugal force helps recover fine protein solids that are difficult to settle naturally.
Is it suitable for dairy food production?
Yes. It can be configured with SS304 or SS316L wetted parts and sanitary design options.
Can it reduce casein drying costs?
Yes. Removing free water before drying can reduce downstream drying load.
Can it operate continuously?
Yes. The decanter centrifuge is designed for continuous feeding, separation, and discharge.
What affects separation performance?
Feed concentration, particle size, bowl speed, differential speed, and moisture requirements affect final results.
