Device for subjecting bulk goods to heat, cold and/or mechanical treatment

摘要

A device for subjecting bulk goods, especially foodstuffs and semi-luxuries such as coffee beans or cocoa beans to heat, cold and/or mechanical treatment has a drum (3) which has at least one chamber, is essentially cylindrical in particular, is intended to receive the bulk goods to be treated and is mounted so as to be rotatable about its axis. In the drum there is arranged a distributing channel (12) for the fluid with nozzles (18) which open out above the inside surface of the drum (3), especially in the bulk goods. The nozzles are arranged so as to be non-rotating with respect to the drum (3) and to be adjustable if necessary. The outline of the cross-section of a multiplicity of nozzles (18) of the distributing channel (12) takes the form of a streamlined body, at least in the region in which they open out, which is adjacent to the surface of the drum, which streamlined body is oriented in the direction of movement of the drum and extends further in this direction than it does perpendicular to it. <IMAGE>
