Cream Separator: Operating Procedures, Safety Guidelines and Troubleshooting

Cream Separator Operating Procedures and Maintenance

Factors Affecting Separation Efficiency

• Density Difference: The greater the density difference between solid particles and mixed liquid, the better the separation
• Viscosity: Lower viscosity of mixed liquid yields better separation
• Processing Volume: Smaller processing volume allows longer residence time in drum, improving separation
• Particle Shape and Size: More regular and spherical particles with larger size produce better separation

Factors Affecting Production Capacity

• Rotation Speed: Higher speed increases production capacity
• Fat Globule Diameter: Larger fat globule diameter improves separation
• Disc Radius: Larger lower radius and smaller upper radius improve separation
• Disc Angle: Optimally 50-60 degrees with apex angle of 60-80 degrees
• Preheating Temperature: 35-40 deg C (can go to 50 deg C, but no higher to prevent protein coagulation)

Pre-Operation Checks

1. Confirm all separator components are intact, undamaged, and not loose
2. Thoroughly clean interior and exterior ensuring no residue or impurities
3. Prepare material meeting separator processing requirements
4. Check gearbox lubricant quality and level; clean gearbox bottom when changing oil
5. Verify correct assembly of separation bowl and inlet/outlet devices
6. Check that machine cover handwheel is tightened
7. Check suspension loops on inlet/outlet devices for looseness
8. Verify base bolts are tight

Startup and Operation

1. Turn on centrifuge power and gradually accelerate to required rotation speed
2. When target speed is reached, the centrifuge begins operation
3. Avoid overspeed operation to prevent equipment damage or accidents
4. Comply strictly with operating procedures; avoid overload and non-compliant operation

Stopping Procedure

1. Gradually reduce rotation speed until centrifuge stops completely
2. Due to high rotational inertia, free stop time exceeds 30 minutes
3. Brake can reduce stop time to approximately 10 minutes
4. Brake surface is on coupling friction drum with limited braking torque

Safety and Maintenance

• Do not place hands or other objects in the rotating area to prevent injury
• Avoid overspeed operation to prevent equipment damage or accidents
• Lubrication: Regularly lubricate bearings, gears, and other components to reduce wear and noise
• Cleaning: Frequently clean exterior housing and internal components. Maintain clean working environment. After each use, promptly clean centrifuge tubes and bowls to prevent residue corrosion.
• Corrosion Prevention: Regularly inspect metal components, especially those in contact with materials. Treat any corrosion promptly.
• Electrical Inspection: Regularly inspect electrical components for safety and stability
• Bowl Maintenance: Bowl component lifespan depends on material properties, operating environment, and conditions. Internal scale should be regularly treated.
