REVIEW ON PNEUMATIC UPLIFTING MECHANISM OF BI-DIRECTIONAL MIXER

– Various types and styles of mixing equipment are utilized within the food industry. Their use and application are determined by the phases being mixed (liquid-liquid, solid-liquid, or solid-solid) as well as physical characteristics of the end product (like viscosity and density). In reality, many mixing technologies overlap in use and function such that certain applications can actually be successfully produced by two or more types of mixing systems. In these situations, economics rules out the more costly initial investments, but differences in efficiencies must also be taken into account. Proper mixer selection is vital to process optimization. In conventional method of mixing the metal oxide powder and vehicle mixing is carried out on ‘Unidirectional Stirring Machine’ The stirrer of conventional machine rotates in one direction only which creates a particular flow pattern in the fluids hence the particles tend to stick to the walls of container owing to the centrifugal force rather than mixing thoroughly in mixture of paint, ultimately results into poor quality mixture of paints there by poor quality output of paint. In order to have a homogeneous mixing would be appropriate to have a directions of rotation of stirrer shaft which will rotate stirrer blades in opposite directions with spiral blades applications in one cycle this will form turbulent flow pattern there by leading to creation of irregular flow pattern and resulting into thoroughly mixed paint mixture preparation which will create the good quality paint in additional pneumatic ram which dynamically move drive head of mixer in up & down direction.
