On 21th  November, The trial run of Jieya TRP120 devolatilization extrusion system of an Taiwanese customer was successful!



two rotor extruder

As we all know, twin screw extruder is the key equipment in traditional plastic compounding extrusion industry. It can realize the blending modification, reaction, devolatilization, extrusion, granulation and other processes of polymer. It is one of the core equipment in the plastic industry.

To meet the growing demand of products with low VOC and low residue ,Jieya has independently researched and developed the two-rotor devolatilization extrusion system for downstream customers.These extruders are equipped with special features to remove volatile components from the material being processed.The devolatilization process in an extruder typically involves heating the material to release the volatile components through a vaccum system. 


  • New high-efficient chemical processing equipment for high viscosity material systems.

  • Used for various polymerization reactions (polycondensation, polyaddition), high-capacity devolatilization, evaporating concentration, phase-change crystallization, heat and mass transfer, distribution mixing, and other operations.

Two screw devolatilization extrusion system shows advantages:

  • Integrates the self-cleaning capability of the twin-screw extruder with the ability to handle high-viscosity materials, the large heat exchange area of the thin-film evaporator, and the large working volume of the reaction vessel, overcoming inherent weaknesses and bottlenecks of each traditional processing equipment.

  • Unique different speed intermeshing two screw structure with excellent self-cleaning, superior distribution mixing effects, and outstanding heat and mass transfer and interface renewal

  • Ample working volume and gas space, easily meeting the requirements for continuous reactions with long residence times, exhaust devolatilization operations with high volatile content, and large-scale industrial production capacity needs.

  • Both the main body and two screws can be heated or cooled, providing a larger heat exchange area.

  • Lower shear rates significantly reduce damage to the performance of sensitive materials.

  • Can meet the demanding requirements of complex operations such as high vacuum, explosion-proof, toxic, and phase changes in accompanying material systems.

  • Jieya has modular, multifunctional TRP and two-rotor reaction devolatilization complete experimental devices, providing strong support for the feasibility verification, innovative development, and engineering scale-up of new materials, processes, and technologies.

Our company is one of the leading manufacturer of parallel corotating twin screw extruders in China, with independent R&D. Nanjing Jieya is customer-oriented and experienced at different plastic compounding fields and industries, which will bring better service experience and create higher value for customers.
