Hydronix Sensors for Concentration Measurement in Powder Production - Application note

When manufacturing powders, for example dried drinking chocolate, it is common practice to concentrate a liquid before spray drying and this is typically done in an evaporator. The material is then processed through a spray drier where the remaining moisture is evaporated leaving fine particles of powder.  Measuring the precise level of concentration of the liquid to identify the point at which it can be discharged can achieve considerable savings in the reduction of wasted materials and also provides increased and consistent product quality.
