Drying in a new two impinging streams reactor

A new gas-solid reactor, employing two impinging streams with oscillatory motion of the solid particles, was developed and successfully tested in evaporation experiments. Comparisons of the performance of the reactor with other commonly used devices, namely, spray dryer, spouted bed, stream dryer and a fluidized bed, indicated a most high efficiency in carrying out drying of moistened particles by a hot stream of gas. In addition, the pumping work per kg of solids transported by air through the reactor is considerably lower in comparison to a fluidized bed.
