MIXING BATCH TUB REACTOR CONVERSION

We provided the mechanical and electrical engineering needed to upgrade a vintage 1905 candy mixing tub to a modern mixing reactor for batching monocalcium phosphate. The reaction, which takes place during mixing, brings the product to a consistency of wet concrete before crystallization. Over 300-hp worth of mixing energy is dissipated into this restored tub. A 200-hp adjustable frequency drive was employed to adjust the speed of the mixing rotor during different stages of the reaction. Rhone-Poulenc engineers had estimated around a million dollars at that time to buy and install a new modern mixer along with the relocations of auxiliary equipment. Using this approach, total project cost was under 100k.
