In the world of high-viscosity material processing, choosing the right mixer can significantly impact product quality, efficiency, and consistency. At Simptek Machine, we are proud to introduce our Vacuum Sigma Kneader Mixer—engineered for superior mixing, kneading, and vacuum degassing performance in one compact, powerful system.
A Vacuum Sigma Kneader Mixer is a robust batch mixer specifically designed to handle high-viscosity materials such as rubber compounds, chemical ,adhesives, sealants, silicone, resins, dough etc. The kneader mixer consists of two counter-rotating sigma-shaped blades housed in a horizontal, jacketed mixing chamber, which create a kneading and folding action in order to ensure thorough mixing.
When equipped with a vacuum system, the vaccum kneader sigma mixer enables degassing during the kneading process—essential for air-sensitive or high-purity formulations.
Key Features:
Heavy-Duty Sigma Blades: Designed for intensive kneading, ensuring thorough dispersion and uniformity.
Vacuum Operation: Removes trapped air and moisture, improves material quality and shelf life.
Jacketed Chamber: Enables precise temperature control through heating or cooling media.
Custom Capacity: Available in sizes ranging from lab-scale (1L) to industrial production scale (5000L+).
Automated Discharge Options: Including hydraulic tilt, bottom discharge valve, or screw extruder for efficient product removal.
Vacuum mixing involves mixing under a vacuum (below atmospheric pressure), which result in a reduced amount of air. It not just ensures cleanliness during the mixing process but also can achieve various purposes includes:
Avoiding foaming / Degassing:
The vaccum mixing process prevents the formation of bubbles if excess air enter in during the mixing and blending process. Existing bubbles within the sample also disappear due to the pressure difference with the environment, which prevent turbidity, discoloration, and aesthetic issues. It helps to improve product stability, its strength and structure of materials.
Reducing oxidation reactions:
The vaccum mixing chamber create a vacuum environment by removing air and oxygen during mixing ,so that prevents the decomposition of air-sensitive substances and inhibits microbial growth and chemical reactions. This help to enhance product stability and improve product quality.
Wide Applications:
The Vacuum Sigma Kneader Mixer is ideal for industries such as:
* Silicone and Elastomers
* Lithium Battery Slurry
* Hot Melt Adhesives
* Pharmaceutical Pastes
* Ceramic Mass and Metal Powders
* Chemical,Plastic,Rubber
* Carbon,Medicine,Food Industry
