Vertical Pelletizing Extruder (Cooling Type)
Pharma extruder with an integrated cooling mechanism to handle heat-sensitive materials for pharmaceutical products and drugs
The cooling-type vertical pelletizing extruder is an advanced model developed based on the standard vertical design, enhanced with integrated cooling, anti-slipping, and precise temperature control functions. It is engineered for processing temperature-sensitive materials used in pharmaceutical production.

- Efficient temperature control
The cooling system maintains the extrusion zone within a temperature rise of ≤5 °C (with chilled water) or ≤10 °C (with tap water), ensuring stable operation without heat buildup. - Stable material feeding
The extruder prevents material slippage during processing, maintaining uniform extrusion and consistent product quality. - Reliable sealing and easy maintenance
Equipped with a main inlet and outlet for cooling water, featuring quick-connect couplings for easy setup and disassembly without leakage. - Continuous production for heat-sensitive materials
Enables efficient continuous extrusion for temperature-sensitive compounds, improving productivity and expanding material compatibility. - Automated temperature monitoring
The system continuously measures and regulates the material temperature in real time, ensuring optimal process conditions.
Ideal for the production of heat-sensitive pharmaceutical pellets and sustained-release formulations such as ibuprofen extended-release micro-pellets, as well as other active pharmaceutical ingredients (APIs) requiring precise temperature control during extrusion.
This extruder is typically paired with a spheronizer to form a complete pelletizing system.
For powder processing, we also provide a one-stop solution.
What are the key upgrades of the cooling type vertical palletizing extruder compared with a standard extruder?
Three major technical advancements distinguish the cooling type extruder:
- Precise temperature control: The extrusion zone maintains a temperature rise of ≤5 °C (with chilled water) or ≤10 °C (with tap water), effectively preventing degradation of heat-sensitive materials.
- Anti-slipping design: The extrusion chamber features a special surface treatment and an adaptive pressure control system, eliminating slippage and material blockage during operation.
- Intelligent monitoring: Real-time temperature monitoring and automatic adjustment of extrusion parameters ensure consistent processing and stable product quality.
Does this extruding equipment meet pharmaceutical industry compliance requirements?
It is fully compliant with pharmaceutical manufacturing standards:
- Material: All contact parts are made of 316L stainless steel in accordance with FDA requirements.
- Cleaning: Supports CIP/SIP cleaning with dead-space residue less than 0.01%.
- Documentation: Includes complete IQ/OQ/PQ validation documentation and SAT protocol covering the temperature control module.
