The latest food and beverage industry news and trend analysis

GEA has announced the launch of the GSE 150 CPR, a new clarifying separator specifically engineered for pulp-rich citrus juices. The machine targets medium-capacity processors who are increasingly challenged by fluctuating raw material quality. The launch arrives as the global citrus industry faces significant pressure from the HLB (citrus greening) plant disease and extreme weather conditions in major production hubs like Brazil.

According to Fundecitrus, approximately 48% of the Brazilian Citrus Belt is currently affected by greening, resulting in smaller fruits with lower juice content and uneven solids. The GSE 150 CPR is designed to stabilise the clarification process under these variable conditions while minimising juice losses.

Technical Innovation in Continuous Pulp Discharge

The core of the GSE 150 CPR is its Constant Pulp Removal (CPR) technology. Unlike conventional separators that rely on intermittent solids discharge, this model utilises a specialised separating disc and a second centripetal pump. This configuration allows for the continuous conveyance of pulp out of the machine under pressure of up to 4 bar.

By removing the reliance on solids-holding volume for process stability, the machine can handle highly fluctuating pulp content without frequent interruptions. Technical performance indicators show that CPR separators can process approximately 50% more product than conventional separators of a similar size. During standard operation, the GSE 150 CPR requires only two to four solids discharges per hour, compared to up to 30 discharges per hour for traditional models under high solids loading.

Precision Control and Texture Management

The move toward premium juice products has increased the demand for defined texture profiles, where pulp content is a specific quality parameter rather than a variable. To meet this demand, the GSE 150 CPR includes several operational features:

• Automatic Pulp Control: An optional system that measures discharge viscosity to adjust pulp flow, reducing losses during batch changeovers.

• Variable Capacity: The system supports throughputs of up to 17,000 litres per hour for orange juice and 12,000 litres per hour for lemon juice.

• Versatility: Beyond standard juices, the separator is suitable for pulp washing processes and cloudy peel extracts.

Rüdiger Flocke, Area Sales Manager for Beverage at GEA, stated that process stability has become a critical economic lever as raw fruit quality fluctuates. He noted that the continuous discharge under pressure makes clarification more robust and directly reduces product loss.

Context for Global Demand

The launch complements GEA’s existing CPR series and is strategically positioned for processors in growing markets such as Egypt, Turkey, and Southeast Asia. In these regions, the use of oranges for processing is increasing, creating a requirement for efficient, professional-grade separation technology that balances investment costs with high throughput.

Global stocks of Brazilian orange juice concentrate reached a historic low in 2025, meaning any processing losses now have a direct impact on producer margins. Furthermore, market trends identified by Innova Market Insights show a growing consumer preference for natural products differentiated by specific textures and pulp content, placing higher technical demands on the clarification stage.

Engineering and Maintenance Specifications

The GSE 150 CPR is constructed with stainless steel components that meet food processing hygiene requirements and is fully CIP (Clean-in-Place) capable. The drive system utilises a low-maintenance flat belt powered by a 30-kilowatt motor, with the bowl rotating at 5,300 revolutions per minute.

For high-availability operations, GEA offers the InsightPartner Separation Monitoring system. This digital condition-monitoring tool records vibrations and other performance data to enable condition-based maintenance, further reducing the risk of unscheduled downtime in volatile processing environments.
