The invention relates to a method and devices for short-time heat
treatment and/or quenching of bulk materials and can be used for the
chemical, food, wood and other industries. The inventive method for a
pulse heat treatment of bulk materials consists in evaporating surface
moisture, rapidly heating to a required temperature and in subsequently
cooling by supplying particles to a rotating surface whose temperature is
greater than 100.degree. C., wherein the contact of particles with the
hot surface is carried out by means of centrifugal forces, the time of
contact and a pressure force are controlled by modifying the speed of
rotation of the hot surface and the particle quenching stage is carried
out on a cooling plate by the rapid cooling said particles and collecting
a final product in an accumulator. The treatment of moving bulk material
particles is carried out on the rotatable cylindrical or conical hot
surface on which an excessive moisture evaporating stage and stage for
heating to the required temperature are combined. The time of the
material displacement along the hot surface by the gravity force are
controlled by a friction force which is adjustable by modifying the speed
of rotation. A device for carrying out said method is also disclosed.
