Horsepower: The Effects of Impeller Diameter and R.P.M.

The power or energy applied to a mixing process is always an essential component to successful results. This may seem like a very obvious concept, but after 32 years in the business of providing mixing solutions, I am certain that very few mixer users understand how the horsepower of a mixer motor actually effects and is applied to their process.

Many simply feel more horsepower is better. Others are sold on the idea that energy efficiency or less power as a result of ‘impeller technology’ or drive efficiency is a modern panacea.

The facts are, you can’t mix your process without power and all the power applied is in the form of flow and velocity head. Anyone can find the optimum level of each by endlessly testing at full scale with different impeller diameters and R.P.M. However, a much wiser approach would be to contact Brawn and let us employ our decades of knowledge and expertise to zero in on the right combination with little or no need for testing.

Sanitary Mixing: FSMA and Cleanability

The Food Safety Modernization Act was signed into law on January 4, 2011 by President Obama. Like it or not, this is the most sweeping reform of our food safety laws in over 70 years. One thing is certain: food and beverage manufacturers will be scrutinized more thoroughly than ever before with regard to their practices for producing their products.

As far as mixing is concerned, Brawn Mixer, Inc. has been building stainless steel and sanitary mixers from its beginning in 1993. Today Brawn remains a leader and innovator when it comes to helping food and beverage producers solve the problems of mixing their products safely. Standard motors in both electric and pneumatic form are Brawn standard options as are stainless steel gearboxes. Sanitary seals are also options for preventing product side contaminants.
