Industrial Equipment Batch or Continuous Flow

We therefore believe that industrial scale technological management of microwave-assisted chemical reactions is not compatible with batch reactors coupled with multimode applicators. Typical processes with systematic reduction of the dielectric losses of reactant under consideration, for example filtration and drying of mineral or pharmaceutical powders are compatible with multimode applicators. 

As far as we are aware, the only industrial batch microwave device is the micro-wave variant of the Turbosphere all in one solution mrxer/granulator/dryer 

This first industrial device was designed by MBS [122] for drying. It could be used for solid-state reactions with powder reactants. The reactor cannot, therefore, be a classical chemical vessel or a classical chemical reactor with stirrer and other associated technical devices but a container able to enclose a reactant powder layer. The geometric shape of the microwave applicator is parallelepipedical box and the reactants are supported by a dielectric conveyor belt with edges, as shown by Fig. 2.37. 

Each applicator is connected to one or two microwave generators on both sides of the equipment (courtesy of M. Delmotte and MBS company). The conveyor belt passes through several large open parallelepiped applicators. The geometric structure of the waveguides is derived from a standard waveguide adjusted to the TEoi mode at a frequency of 2450 MHz [122]. After interface matching of the layer of 

This equipment could be used for chemical reactions based on strong solid-gas interaction with gas adsorbed on powder, for example limited air oxidation, or with gas release (water, ammonia), for example esterification. The oversized applicator structure enables design of a dielectric pipe to manage such matter transfer. This equipment can be also used for many reactions on solid supports. A typical unit is powered by microwave generators units of 2 or 6 kW for a total microwave power close to 20 or 60 kW.
