Frequently Asked Questions
Direct answers to the most searched technical and commercial questions about bio extrusion systems.
What is a bio extruder and what materials can it process?
A bio extruder is a specialized twin-screw extrusion system designed to process heat-sensitive, bio-based materials. It features precise low-temperature zones and specialized screw geometries to prevent thermal degradation.
Materials processed include: PLA, PHA, PBS (biopolymers), starch-based polymers, agricultural biomass composites, biodegradable packaging materials, organic fertilizers, and pharmaceutical compounds.
Why choose twin-screw over single-screw for bioplastics?
Twin-screw extruders are overwhelmingly preferred for bio-materials due to:
- Superior Mixing: Co-rotating twin screws provide exceptional distributive and dispersive mixing.
- Precise Temperature Control: Independent zone control (±1°C) prevents thermal degradation.
- Self-Wiping Action: Prevents material stagnation in narrow-processing-window bio-materials.
- High Viscosity Handling: Superior conveying efficiency for sticky biomass that would clog single-screw systems.
What is the optimal L/D ratio for biomass extrusion?
The optimal Length-to-Diameter (L/D) ratio depends on your application:
- L/D 32:1 – 36:1: Laboratory R&D, low-viscosity biopolymers.
- L/D 36:1 – 40:1: Pilot-scale production, conventional biopolymers (PLA, PBS).
- L/D 40:1 – 44:1: Industrial production, high-viscosity biomass, intensive mixing.
- L/D 44:1 – 52:1: Maximum mixing intensity, devolatilization, complex multi-stage processes.
We recommend L/D 40:1 as the optimal balance for most bio-material applications.
Can bio extruders handle high-viscosity or sticky biomass without clogging?
Yes, when properly configured. Our bio extruders feature:
- Optimized Screw Geometry: Progressive pitch variation prevents material bridging.
- Precise Temperature Control: Multi-zone heating prevents cold spots causing solidification.
- Anti-Clogging Monitoring: Real-time torque and pressure sensors with automatic speed adjustment.
- Forced Feeding: Optional gravimetric feeders with agitation prevent hopper bridging.
What is the typical output capacity and delivery time?
Output Capacity: Lab-scale (10-50 kg/hr), Pilot-scale (150-350 kg/hr), Industrial (500-900 kg/hr), Large-scale (1000-1800 kg/hr).
Delivery Time: Standard models: 2-4 weeks. Customized configurations: 6-8 weeks. Shipping: 2-6 weeks depending on destination.
Payment Terms: 30% deposit, 70% before shipment (T/T), L/C accepted for orders above $50,000.
Do you provide customization and after-sales support?
Yes, comprehensive support includes:
- Custom Configuration: Screw design, L/D ratio, metallurgy, and temperature zones tailored to your material.
- Warranty: 12 months comprehensive (24 months for core components: screws, barrels, gearbox).
- Installation: On-site commissioning by certified engineers and 3-5 days of operator training.
