ABSTRACT:
Bulk products are cooled by feeding them into a substantially horizontal drum that rotates about its axis. The drum is housed within an insulated enclosure and has a perforated cylindrical wall. The enclosure is subdivided by a wall that extends parallel to the axis of the cylinder; and this latter wall is sealed against the cylinder in such a way that access between the two sides of this latter wall can only be through the cylinder. Cooling gas is then forced upwardly through the cylinder by a fan disposed in this latter wall. The holes through the cylinder are in the form of peripherally elongated slots; and a brush in continuous contact with the periphery of the cylinder not only provides a portion of the seal that forces the cooling gas to pass through the cylinder, but also cleans these slots.
