XUANYU Centrifugal Separators for Dairy Processing
News 2022-06-14
XUANYU Centrifugal Separators for Dairy Processing are industrial-grade disc-stack centrifuges engineered for high-precision separation in milk, whey, and dairy product manufacturing. They deliver 99.5%+ fat recovery and clarify down to 3μm solids, enabling cream skimming, milk clarification, whey purification, and bacteria reduction (bactofugation) while preserving nutritional integrity and product freshness. Ideal for dairy plants of all scales, they support continuous 24/7 operation with food-grade safety, low product loss, and easy integration into automated processing linesGEA.
Core Advantages
- Food-Grade Hygiene & Safety: Wetted parts in AISI 304/316L stainless steel with crevice-free, polished surfaces (FDA/3-A compliant); fully sealed design prevents cross-contamination. CIP-ready with self-cleaning bowl and automatic sludge discharge for minimal manual intervention.
- Ultra-High Separation Precision: High-speed disc-stack bowl (6,000–12,000 rpm) generates 4,000–6,000×g centrifugal force; optimized disc spacing and flow paths ensure sharp separation of cream, skim milk, and solids (sediment, somatic cells, bacteria). Fat in skim milk can be reduced to ≤0.03% for standardization; solids removal efficiency ≥99%.
- Gentle Product Handling: Hydrosoft feed system minimizes shear to protect fat globules and protein structure; preserves taste, texture, and nutritional value in milk, cream, and wheyGEA.
- Continuous & Reliable Operation: Self-cleaning (purge-type) bowl with automatic solids ejection extends runtime and reduces product loss; heavy-duty bearings and vibration-damped frame enable 24/7 production with low downtimeGEA.
- Flexible & Cost-Efficient: Adjustable cream fat content (10–45%) and flow rates (500–10,000 L/h) to match product specs; energy-efficient motor with VFD control cuts power use by 15–20% vs. conventional units. Modular design integrates with pasteurizers, homogenizers, and filling lines.
- Smart Process Control: PLC+HMI touchscreen for real-time monitoring of flow, temperature, pressure, and fat content; remote access, fault alarms, and data logging for predictive maintenanceGEA.
Working Principle
- Feed & Acceleration: Raw milk/whey enters the rotating bowl via a central pipe and accelerates smoothly through the disc stack, avoiding shear damage to fat globulesGEA.
- Centrifugal Separation: High centrifugal force drives denser skim milk to the bowl periphery; lighter cream migrates to the center; solids (sediment, bacteria) settle on the bowl wall.
- Fractionated Discharge: Pressurized outlets for skim milk (peripheral) and cream (central) enable continuous, pressure-driven transfer to downstream processes.
- Solids Ejection: Self-cleaning bowl periodically ejects sludge via nozzles or valves without stopping, ensuring consistent performance and reducing product lossGEA.

Key Applications
- Milk Skimming: Separate cream from raw milk for standardization (whole, low-fat, skim) and cream production (10–45% fat).
- Milk Clarification: Remove sediment, somatic cells, and fine solids to improve shelf life and product quality.
- Whey Processing: Purify whey from cheese manufacturing to produce whey protein concentrate (WPC) and lactose solutions.
- Bactofugation: Reduce bacteria/spores (e.g., Clostridium botulinum) in milk to enhance food safety and extend product shelf life.
- Cream Concentration: Upgrade cream to 35–45% fat for butter, ice cream, or condensed milk productionGEA.
Customization Options
- Process Configuration: Clarifier (solids removal), separator (cream skimming), or bactofuge (bacteria reduction) modes.
- Material Upgrades: 316L stainless steel for corrosive products; food-grade PTFE gaskets; heated bowl for viscous materials.
