• Sigma Mixer R&D Lab Model


Lab Sigma Mixer is a small sized compact model that is commonly uses for small batch production and it finds it application in research laboratories and institutions. It is highly reliable for the production of high value products that are required to be produced in small batches. Entirely manufactured with stainless steel 304/316, it has a sturdy structure.

As a premier manufacturer, we manufacture laboratory kneaders in various sizes ranging from 5 kgs. to 50 kgs. The machine has a W shape container that is made either of mild steel or SS 304 or 316. It also has a jacket optionally that covers two sides for heating and cooling application. The mixing blades are sigma type steel casted and these blades contra-rotate at a specified clearance for optimum mixing outputs. Our lab sigma mixer ensures minimal friction and the blades have long service life as well.

The machine is manufactured according to good engineering practice and hence it is worth your penny. Owing to safety features such as over load protection & enclosed drive, our laboratory kneader is extremely safe to use. If you need optional features such as hydraulic lifting/unloading & spraying system, we can make it happen for you as well.

Salient Features of Lab Sigma Mixer

  • Option of Stainless Steel 304, 316 and Mild Steel materials.
  • Compact in size and easy to use.
  • Surface finish mirror or matt as per user requirements.
  • Suitable for mixing dough type materials as well stiff pastes.
  • Jacket can be offered for heating and cooling process.
  • Insulation on jacket for safety from heat.
  • Tangential type Z shaped blades for uniform mixing process.
  • Teflon shaft sealing for food grade usage.
  • There is minimal gap between blades and inner surface for proper mixing operations.

Working Principle of Lab Sigma Mixer

Mixing is the main activity in any industrial blending process. Homogeneous mixing ensure quality of final product which is key for quality finish product. Sigma Mixer perform tangential action kneading through its Z shapes blades. These Z shaped blades rotates in opposite direction to each other which makes mixing really easy. Through option of adjusting RPM of blades one can achieve quality mixing. As some products required slow speed mixing when adding liquid to avoid foaming & overflowing. For discharge of product tilting and screw extruder system can be offered.

Mixing action is combination of various activities which generate vertex for homogeneous mixing operations. Shearing action between blades and side walls resulting reduction of solid product. Ratio of front and rear blade usually is 3:2 for mixing of heavily viscous products.

In case of overlapping mechanism blades overlap one saddle of the bowl. In overlapping action it is essential that the relative position of the two blades are unchanged. Both the blades rotate with equal speed. Product flow freely into the blades are mixed by overlapping blade action.

Discharge mechanism are two types – one is hydraulic tilting through pneumatic operated power pack system and second is mechanism tilting through induction & gearbox. Suppose if after kneading product is needed to be in specific form then side discharge screw system offered.
