Product Overview
PROMIX-11 is a floor-standing 11 mm lab-scale twin-screw extruder intended for R&D and small-batch processing. It supports formulation development, material screening and early-stage process research with low material consumption, enabling evaluation of feeding behaviour, melting, screw configuration, additive dispersion, torque response, venting and pellet quality.

Description
Continuous twin-screw extrusion integrating feeding, melting, venting and discharge. Typical configuration allows easy integration with upstream material handling and downstream pelletizing, cooling or analytical equipment. Suitable for polymer compounding, elastomer testing, engineering plastics, bio-based materials and pharmaceutical extrusion research and scale-up trials.

Design Highlights

• CIP cleaning kit: insert cleaning hose into adapter port to flush screw and barrel; screw elements and barrel are detachable and washable.
• Barrel operating device: process units can be disassembled using dedicated barrel tools after disconnecting.
• Modular machine design: quick assembly and disassembly of segments and screw elements.
• Heater housing: stainless-steel mirror-polished finish for easy cleaning and corrosion resistance.

The Lemix Control System Enables
Centralised data acquisition and equipment status monitoring with user authority management and security features designed for regulated environments:

• Audit trail
• Electronic signature
• Recipe management and batch record reporting
• Full process recording and traceability
• Encrypted, tamper-evident database files
• Comprehensive change logging
• Local and remote historical data backup

Applications

• Hot Melt Extrusion (HME): disperses APIs into polymer carriers (e.g., PVP, methacrylates, cellulose derivatives) to form solid dispersions; enables molecular-level dispersion to improve dissolution and bioavailability of poorly soluble drugs.
• Solid Lipid Extrusion: cold or low-temperature extrusion of lipid matrices for thermosensitive APIs without solvents.
• Granulation: continuous twin-screw granulation via wet or melt granulation; adjustable mixing intensity for targeted pellet or granule properties.
• Transdermal Preparations: formulation and processing for implants, patches and topical dosage forms.
• Pharmaceutical 3D Printing: formulation homogenisation and melt extrusion feedstock production for additive manufacturing.
