Decanter Centrifuge for Lemon Juice Processing
Description
The Decanter Centrifuge for Lemon Juice Processing is designed for continuous separation of lemon pulp, fiber, and suspended solids from citrus juice.
It is suitable for lemon juice clarification, citrus pulp recovery, fruit processing wastewater treatment, and juice concentration pretreatment. The centrifuge separates fine solid particles from liquid through high centrifugal force, improving juice clarity and reducing product loss.
In lemon juice production, the main challenges include fine pulp particles, high fiber content, unstable solids concentration, and strict food-grade hygiene requirements. The decanter centrifuge provides continuous operation, efficient clarification, and reliable solid-liquid separation for citrus processing plants.
Typical Applications
- Lemon juice clarification
- Citrus pulp separation
- Fruit juice solid removal
- Lemon concentrate pretreatment
- Citrus processing wastewater treatment
- Fruit fiber recovery
- Juice production line solid-liquid separation
- Citrus by-product recovery
Lemon Juice Processing Challenges
Fine Pulp and Fiber Separation
Lemon juice contains fine pulp particles, fiber, and suspended solids that are difficult to remove by traditional settling.
Juice Yield Loss
Valuable juice remains trapped in pulp and solid residues, reducing overall product recovery.
High Fiber Content
Citrus fiber can affect liquid flow and increase separation difficulty during processing.
Variable Feed Conditions
Different lemon varieties, maturity levels, and processing methods cause changes in solids concentration and viscosity.
Food-Grade Hygiene Requirements
Juice production requires sanitary equipment design to prevent contamination and maintain product quality.
Continuous Production Demand
Large-scale juice plants require stable equipment operation with minimal manual intervention.

How the Decanter Centrifuge Works
1. Lemon Juice Feeding
Lemon juice containing pulp and suspended solids enters the rotating bowl through the feeding system.
2. Solid Sedimentation
Under centrifugal force, pulp particles and fibers move toward the bowl wall and form a concentrated solids layer.
3. Juice Clarification
Separated juice remains in the liquid zone and flows toward the clarified liquid discharge area.
4. Solids Conveying
The scroll continuously transports concentrated lemon pulp toward the discharge end.
5. Continuous Discharge
Clarified juice and dewatered pulp are discharged separately for further processing.
