'''Vertical Ribbon Mixers''' Consist of a tank with its contents recirculated through an upright auger. Actual agitation occurs only in auger which occupies less than one-tenth of the space in a typical 1-ton upright. Can not effectively handle liquid molasses or roughage. Operational efficiency also suffers due to the excessive amount of time required for mixing and unloading when compared with a horizontal mixer. Furthermore, thorough clean out is not achieved.

==Working Principle==
 
First step is charging of mixer from the top, manually or vide pneumatic or mechanical conveying. After the mixer is charged the mixing process starts.                                                 
The mixing is carried by means of 3 distinct intermixing actions:
 
*The screw agitator, turning on its axis, produces a lifting action as it spirals the materials in an upward flow.
*At the same time, orbiting the tank, the screw removes material away from the wall and deflects it into the centre of the tank.
*Material lifted by the screw gravitates downward, thoroughly intermixing with material being spiraled upwards.
                 
The typical speed of the central screw is 70 to 80 Rpm. The Tip speed can fluctuate from 1 to 3 m/s. The result is most intimate intermingling of all ingredients. The mixing time is depending on product characteristics, mixing accuracy and batch size
