The Bubble Gum Mixer, also widely known as a Sigma Blade Kneader or Sigma Mixer, is a robust industrial machine specifically engineered for mixing and kneading highly viscous, sticky materials. It plays a critical role in bubble gum production and chewing gum manufacturing, where uniform blending of gum base is essential for consistent product quality.
A Sigma Blade Kneader features a unique double-arm configuration with two sigma-shaped (Z-shaped) blades that rotate at different speeds. This design creates powerful shear forces, folding actions, and excellent material displacement, making it far superior to standard mixers when handling tough, dough-like substances. The overlapping blades ensure every portion of the batch receives thorough mixing, eliminating lumps and delivering a homogeneous final product.

It is a robust industrial Sigma Blade Kneader (also called a Sigma Mixer) specifically designed for highly viscous, sticky materials like gum base. It uses two counter-rotating Z-shaped (sigma) blades that create powerful shear, folding, and displacement actions, delivering homogeneous mixing that standard mixers cannot achieve with tough, dough-like substances.
The machine is offered in the key industrial sizes highlighted on the page: 150 liters, 200 liters, 300 liters, 500 liters, and 1000 liters working capacity (with corresponding gross capacities). Larger and smaller models are also listed in the technical specifications table for flexibility.
The mixer is built from heavy-duty Mild Steel (MS), SS 304, or SS 316. Mild-steel versions receive a rust-inhibiting red-oxide primer plus dual-layer epoxy paint. Stainless-steel contact parts can be finished in matte or high-reflectivity mirror polish according to customer preference.
Two precision-engineered tangential ‘Z’-profile blades rotate at different speeds (typically a 3:2 ratio). This creates continuous axial transfer, stretching, folding, splitting, and re-blending of the material, generating the high shear needed for thorough homogenization of sticky gum bases while eliminating lumps and unmixed zones.
Yes. Optional temperature-control jackets allow external heating or cooling. The trough is insulated with high-density mineral wool and protected by external metal cladding so batch temperature remains consistent throughout the cycle, helping preserve ingredient integrity.
Completed batches can be unloaded via manual hand-wheel tilting, automated hydraulic tilting, bottom-mounted discharge valves, or a lateral extrusion screw positioned beside the mixing chamber, giving operators flexibility to match their production line.
An ultra-tight clearance tolerance between the blades and the inner trough wall virtually eliminates product accumulation. Food-grade PTFE shaft seals further ensure sanitary, leak-free operation and easy cleaning.
While optimized for bubble gum and chewing gum production, the same machine is widely used for other high-viscosity formulations such as adhesives, elastomeric compounds, pigments, dyes, carbon pastes, clay slurries, cosmetics, creams, and pharmaceutical ointments.
Motors are available in both general-duty and heavy-duty ratings matched to capacity. Examples include 15–20 HP for the 150-liter class, rising to 60–70 HP for the 1000-liter class. Voltage can be configured to suit local power-supply requirements.
Yes. Modular upgrades available on request include vacuum integration systems, controlled fluid-spray mechanisms, alternative blade configurations (tangential or overlapping), special material/finish combinations, and variable-speed drives to meet specific process needs.
