Engineered for Polymerization and High-Viscosity Applications
The KARVIL 5L Vacuum Electric Heated Sigma Kneader with Screw Extruder is a state-of-the-art industrial mixer, meticulously designed for laboratory, pilot-scale, and small-batch production involving complex chemical reactions and highly viscous materials. This unit's capabilities are perfectly suited for demanding processes such as polymerization reactions (e.g., the synthesis of PET from terephthalic acid and ethylene glycol) where precise environmental control, efficient mixing, and reliable discharge are paramount.
Our commitment to quality is underscored by its recent production for a discerning U.S. client, affirming KARVIL Machinery's reputation for delivering robust and high-performance solutions globally.
Detailed Features
Optimized for Polymerization with Precise Temperature Control
The integrated electric heating jacket, utilizing a purified water medium, enables stable and accurate temperature management up to 80°C. This precise control is crucial for delicate polymerization reactions, ensuring optimal reaction kinetics and consistent material properties.
Efficient Vacuum Processing for Enhanced Purity
Our comprehensive vacuum system, featuring a dedicated pump, buffer tank, and robust metal hoses, effectively removes moisture, volatile components, and entrapped air. This capability is vital for achieving higher product purity, improving reaction efficiency, and managing solvent recovery in sensitive processes.
Superior Sigma Blade Mixing for Homogeneous Blending
The heavy-duty Sigma blades are engineered to deliver intensive shear and thorough blending for highly viscous and semi-solid materials. Powered by a 1.5 kW Siemens-Bade motor with VFD control (0-42 rpm fast, 0-35 rpm slow), it ensures homogeneous dispersion, consistent product quality, and efficient reaction completion.
Reliable Screw Extrusion Discharge for Clean Material Removal
The reversible screw extruder mechanism guarantees complete and efficient material removal from the mixing chamber. This feature is particularly advantageous for sticky or hard-to-handle viscous products, significantly reducing material waste, simplifying cleaning procedures, and minimizing manual intervention.
