Induction heating Mixer

Depending upon the viscosity of the components being mixed, the mechanisms used in mixers are similar to those for heat transfer when fluid paths are disturbed to create turbulence. The design of many types of mixers has improved in leaps and bounds recently, and mixing combined with reactions, together with induction-heated mixers , are of particular interest to PI engineers (see below and Chapter 5). 

Heat and mass transfer has already been included in the discussion of kinetics, but it is worth mentioning some of the areas where intensified heat and mass transfer are attractive, but no reactions are taking place. Several of the applications of PI discussed in Chapters 9 and 10 are of this type and highly compact heat exchangers, electrical enhancement methods, such as ultrasound, and induction-heated mixers are examples of where a need to improve heat and/or mass transfer has been recognised. In some of these examples the heat transfer may be limiting because of the nature of the material being heated or cooled. As discussed in Chapter 9, the...

The mixer used, for example, in a stirred tank, can be given a boost in performance by generating heat in the blades of the mixer itself. Conventionally, in a stirred vessel, the heat input is via a jacket, with conduction of heat through the vessel wall and some forced convection thereafter in the mixed product. Using electrical induction heating via a coil, the paddles themselves can be heated, allowing local reductions in viscosity.
