Abstract
A multiflow rotary heat exchanger element of the type normally used for the continuous processing of various materials through heating, cooling and stirring includes a shaft arranged to rotate within a container and having on its periphery a plurality of planar coil sets, each formed of a number of individual tubular coils. The coils are interconnected to form separate plural conduits, through each of which a fluid passes continuously and simultaneously. The arrangement is such that, during operation, the temperature of a material being processed is uniform in any plane transverse to the container, but uniformly and progressively altered longitudinally of the container.
