1. Product Overview
Our Lab Type 32 Double Screw Extruder (L/D 32:1) is a compact, high-precision co-rotating twin-screw extruder designed for laboratory R&D, formula development, small-batch production, and process simulation in food, feed, plastics, and new materials. With a 32mm screw diameter and modular design, it mirrors full-scale production extruders in performance, enabling accurate data translation from lab to production while minimizing material waste and operational costs.
2. Key Features
- Modular & Flexible Design: 32mm diameter, L/D ratio 32:1 (extendable to 40–48:1); interchangeable screw elements and barrel sections for customized mixing, shearing, and extrusion processes.
- Co-Rotating Fully Intermeshing Screws: Excellent self-cleaning, uniform mixing, and consistent material residence time; ideal for high-shear compounding, reactive extrusion, and delicate material processing.
- Precision Control System: PLC + HMI touchscreen operation; real-time monitoring and recording of temperature (±1°C accuracy), pressure (0–30MPa), screw speed, torque, and throughput; supports data export for analysis and reproducibility.
- Multi-Zone Temperature Regulation: 5–8 independent heating/cooling zones (RT–300°C) with PID control; ensures precise thermal profiling for diverse materials (cereals, proteins, polymers, biodegradable materials).
- Compact & Space-Saving: Small footprint, easy installation and maintenance; stainless steel construction for food-grade hygiene and corrosion resistance.
- High Efficiency & Cost-Effective: Low energy consumption (5.5–22kW motor); output 10–50kg/h, perfect for small-scale trials without full production investment.
- Safety Protection: Overload, over-temperature, and pressure overload alarms; emergency stop button for safe operation.
