Overview
The CEPA Z61 GP Tubular Bowl Centrifuge is an industrial-grade, high-speed continuous separation system engineered for precise clarification and three-phase (liquid–liquid–solid) separation in food, dairy, pharmaceutical, and biochemical processing environments. Operating on the principle of sedimentation under ultra-high centrifugal force, it utilizes a vertically oriented, narrow-diameter tubular rotor to generate up to 17,000 × g at 17,000 rpm — enabling efficient separation of fine particulates, emulsified fats, and suspended solids from low-viscosity aqueous or oily matrices. Designed specifically for compliance with food-grade hygiene standards, the Z61 GP integrates full 316L stainless steel (EN 1.4404 / AISI 316L) wetted components, including feed inlet tubing, cooling jacket, bowl assembly, and discharge trays, ensuring corrosion resistance, cleanability, and regulatory alignment with EC 1935/2004 and FDA CFR 21 Part 110.
Key Features
- High-performance tubular bowl design with nominal rotor capacity of 6 L and continuous throughput ranging from 50 to 1,500 L/h depending on application viscosity and phase density differentials
- Sealed, fully welded 316L stainless steel housing (material grades EN 1.4571, 1.4517, 1.4404, and 1.4307) — all product-contact surfaces constructed to hygienic surface finish Ra ≤ 0.8 µm
- Grease-free bottom bearing assembly with PTFE-reinforced glass fiber guide rings, eliminating lubricant contamination risk and supporting long-term maintenance intervals
- Integrated electronic door interlock system with speed-synchronized safety logic — door remains mechanically locked during rotation and only releases after full deceleration
- 5.7-inch front-mounted touchscreen HMI with three-tier password-protected access levels for parameter configuration, acceleration/deceleration ramp control, and real-time operational monitoring
- Acoustic enclosure design achieving ≤ 80 dBA at 1 m distance, compliant with ISO 4871 and EU Directive 2006/42/EC machinery noise requirements
- Modular electrical interface architecture — all signal and power connections routed externally to simplify integration into plant-wide automation systems
Sample Compatibility & Compliance
The Z61 GP accommodates a broad range of food-grade process streams, including raw milk, whey, plant-based extracts, fruit juice concentrates, and edible oil emulsions. Its validated design supports both single-stage clarification and dual-stage liquid–liquid–solid partitioning using optional specialized rotors. All elastomeric seals contacting product are certified food-grade silicone or virgin PTFE (USP Class VI compliant). The unit meets stringent hygiene requirements per EHEDG Doc. 8 (2022), ISO 22000:2018, and is compatible with Clean-in-Place (CIP) protocols using caustic soda (NaOH) and nitric acid solutions. Optional FAT/IQ/OQ documentation packages support GMP-compliant commissioning and audit readiness per EU Annex 15 and FDA Guidance for Industry: Process Validation.
Software & Data Management
The embedded control firmware provides deterministic real-time response to operational commands and fault conditions. Optional Modbus RTU/TCP communication enables bidirectional data exchange with SCADA or MES platforms, supporting transmission of key status signals: centrifuge start/stop, door open/close state, actual rotational speed, emergency stop triggers, acceleration/deceleration status, and critical alarm codes (e.g., imbalance, overtemperature, seal failure). Audit trail functionality records all parameter changes with timestamp, operator ID, and reason-for-change fields — meeting 21 CFR Part 11 electronic record integrity requirements when paired with validated user access controls.
Applications
- Dairy industry: Skim milk clarification, butterfat recovery from cream, whey protein concentration
- Beverage processing: Juice stabilization, removal of pectin haze and yeast cells
- Plant-based food manufacturing: Separation of starch–protein–fiber fractions from legume or cereal slurries
- Functional ingredient production: Isolation of microalgae biomass, probiotic cultures, or enzymatic reaction byproducts
- Pharmaceutical intermediates: Purification of fermentation broths and cell lysates under cGMP-aligned workflows
FAQ
What is the maximum allowable feed temperature for continuous operation?
The standard cooling coil option supports feed temperatures up to 60 °C; with enhanced cooling configuration, sustained operation at ≤ 85 °C is achievable.
Can the Z61 GP be integrated into an automated production line?
Yes — via optional Modbus interface, PLC-triggered start/stop, and configurable digital I/O for seamless coordination with upstream/downstream unit operations.
Is validation support available for regulated industries?
Factory Acceptance Testing (FAT), Installation Qualification (IQ), Operational Qualification (OQ), and Site Acceptance Testing (SAT) documentation packages are available upon request and executed per ISO/IEC 17025-accredited procedures.
What maintenance intervals are recommended for the grease-free bearing system?
Under typical food-grade operating conditions, the PTFE-guided bottom bearing requires inspection every 6,000 operational hours; no scheduled lubrication is required.
Does the unit comply with explosion protection requirements for solvent-based applications?
The base Z61 GP is not ATEX-certified; however, an ATEX Zone 22 variant (with motor, cabling, and sensor upgrades) can be supplied under separate configuration.
