Salient Features

• Designed in compliance with cGMP (Current Good Manufacturing Practices).

• All product contact parts are constructed from AISI 316/316L stainless steel, while non-contact parts are made from AISI 304 stainless steel or painted mild steel.

• The Universal Double Arm Kneading Machine, commonly known as a Sigma Mixer, features two counter-rotating tangential rotors within a specially shaped trough, curved at the bottom to form two longitudinal half-cylinders with ample overboard volume.

• The main trough is fully welded, and the rotors are taper-bored and key-fitted onto stub shafts that operate on anti-friction bearings. Shaft sealing is provided by PTFE Chevron Rings.

• The counter-rotating tangential Sigma blades ensure effective mixing, with a greater heat transfer area per unit volume and minimal material riding on the blades, optimizing the kneading process.

• In conventional models, a single motor coupled with a gearbox drives the front blade, which transmits part of the power through gear trains to rotate the rear blade.

• Prism Sigma Mixers feature a Dual Drive System that allows two Sigma-configured blades to be driven independently by separate motors and gearboxes, enhancing energy efficiency, reducing vibrations, and minimizing noise levels. This design eliminates the need for external lubricants, preventing product contamination.

• Equipped with a power-assisted hydraulic tilting device for easy and complete material discharge.

• The Sigma-configured blades operate independently, achieving an efficiency range of 95% to 98% due to the use of separate motors and gearboxes.

• The elimination of transmission gears reduces noise levels to 60-65 decibels, significantly lower than industry standards.

• The Dual Drive System delivers power to each shaft independently, allowing for customization of speed ratios between front and rear blades to accommodate different products and recipes. Separate speed control for the motors is also available.

• Smooth power transmission and step-less speed increases via the variable frequency drive (VFD) absorb shock loads effectively.

• The right-angle gearbox design optimizes vertical space, saving over 25% in floor space.

• The Dual Drive Mixer offers significant energy savings since each rotor is driven independently.

• Aesthetic design, user-friendly operation, rugged construction, and high energy efficiency make the Dual Drive Sigma Mixer an ideal solution for demanding mixing applications.
