ABSTRACT:
Apparatus for transferring heat between solid particles includes placing a first granular material composed of particles of a first size on the upper side of a downwardly sloping vibratory screen. The openings in the screen are sufficiently small to prevent passage therethrough of the particles of the first material. A second granular material composed of particles of a second size, smaller than the first size, is spread over the first material on the screen to mix with and sift through the first material as the screen is vibrated. The size of the particles of the second material is small enough to allow passage through the openings in the screen. The first and second materials are at different temperatures so that as the particles of the two materials mix, heat is transferred between the particles. After mixing and heat transfer, the first material flows off the lower edge of the screen where it can be gathered, and the second material flows through the screen where it likewise can be gathered.
