Contra Rotary Mixer

Contra Rotary Mixer is an ideal mixer for the products of high viscosity & density. It is suitable for thorough mixing / blending of tooth paste, grease & other viscous compounds.

WORKING PRINCIPLE
The mixer consists of two different blades rotating clock wise as well as anti clock wise at the same time. It consists of two different shafts having solid & hollow shaft. The solid shaft is provided with multiple paddle blades which rotates in clock wise direction while the hollow shaft with anchor scrapper blades assembly rotates in anti clock wise direction. Intimate & homogeneous mixing of products is achieved by contra rotary motion of two different blades & high speed homogenizer. Vacuum jacketed mixers are provided with vacuum pump, heating arrangement etc.

HOMOGENIZER:
Inbuilt homogenizer with mechanical seal is provided with the bottom dished end for emulsification. It is a chopper type high shear emulsifier. The high shear action creates a forced product flow. The interchangeability of chopper blades are also possible to suit the mixing requirements of various viscous products. On-line homogenizer with specially designed filter can also be provided for re-circulation of the products.

• All contact parts - AISI-304 or 316, 304L or 316L
  
• Jacketed mixers are provided for heating of
  products during mixing.
  
• Provision to mix/blend the viscous products under vacuum for de-aireation purpose.
  
• Mechanical seal is provided instead of stuffing box for main shaft sealing for vacuum operation.
  
• Anchor blade assembly with adjustable Teflon
  scrappers is provided to avoid localized heating & ensure uniform mixing.
  
• Top drive & agitator assembly can be lifted & lowered by motorised as well as hydraulic operations if required.
• Pneumatic System is also available for lifting & lowering top drive & agitator assembly for smaller
  version of Contra Mixers.
  
• Flame proof control panel as an optional.
  
• Available in STANDARD / GMP / cGMP / GAMP / GLP / GCP & Lab Models.

• Uniform mixing & homogenizing of the viscous
  product because of the contra rotary motion with
  homogenizer & anchor blades with scraper
  assembly.
  
• No air contamination because of vacuum operation.
  
• No product contamination because of the sanitary
  design.
  
• Minimum residual product loss because of anchor
