Abstract

Processes and machines for drying or heating particle materials by means of a heat transfer medium that is introduced into the In direct contact with the particle material inside the continuous rotating cylindrical tank, the particle material flows in the overall direction, generally one direction. Through the tank and the heat transfer medium, it generally flows in a straight direction. Cross each other through the tank. Particle material is subjected to heat treatment. By touching the image up close And directly to the medium, relays heat repeatedly during the flow through the tank, while being Separated from the heat transfer medium per tank rotation

Claims (1)

1. a process for drying or heating particle materials, which consists of steps of Bringing the particle material onto one end of the cylindrical tank where The continuous rotation of such length and large cross-sectional area is arranged by a spiral pathway around the wall along the inner circumference of the tank extending almost the entire length of the tank. The heat is transferred to the other end of the tank. The heat transfer medium has a larger particle size. Particle materials and are heated before entering the tank Displacement
