Chewing Gum Sigma Mixer

Chewing Gum Sigma Mixer

Chewing Gum Sigma Mixer comprises of a double 'U' shaped container welded and machined together inside which rotates two 'Z' shaped sigma blades in opposite directions. The clearances between the walls and the container are kept to a minimum to ensure maximum efficiency in kneading and mixing. The shafts of the sigma blades are fitted in bearing blocks which are each provided with roller bearings, steel glands/PTFE rubber seals for smooth and leakless operations. The kneader is mounted on a sturdy base frame fabricated out of ISMC sections and are free from vibrations. For cooling and heating jackets are provided.

These types of machines are available in M.S. And S.S. construction. The kneader can be tilted by means of a mechanical system or manually and for bigger models beyond 250 Kgs we provided hydraulic tilting.

Hydraulic tilting system is provided with complete power pack, electric motor, pressure valves, pipes, fittings, cylinders and hoses which makes the tilting mechanism quick, easy and simple to operate.

Sigma Mixer Operation

Sigma mixer, the tangential action of mixing and kneading is thoroughly obtained by 'Z' (SIGMA) shaped kneading blades, which rotates very accurately at different speed towards each other causing product to be transferred from blade to blade. Discharge of the mixed product is achieved by tilting the container or through the valves at the bottom or by means of an extrusion screw below the container if provided

Sigma Mixer Options

• GMP / Non GMP / models.

• Discharge in sigma mixers is done by tilting container / bottom sliding valves / bottom gates / flush bottom gate valves.

• Tilting in sigma mixers is done by hand liver / hand wheel with lead screw / electrical arrangements / hydraulic systems.

• Lifting of lead either manually, with help of counter weights or hydraulically.

• 'Z' Type Spiral blade / Naben / double naben blades to circulate hot / cold water in cases of heavy masses.

• Jacketed shell for heating or cooling by steam, oil, water etc. with fiber glass insulation over the jacket.

• Spray system for liquid addition / gas purge.

• Flame proof / Non-flame proof electrical controls.
