Berkowicz & Hagenkamp Maschinenfabrik Berhag in Cologne-Ehrenfeld. Fresh air heating device for tobacco roasting machines. Patented in the German Empire on September 13, 1921.

The present invention relates to heating devices for the fresh air required by hot tobacco roasters.

In the previously known devices of this type, the "air to be introduced into the drum" is heated in the cone in hcizkaiiiinern with cast-iron walls, which are wired with so-called heating fans the Blechummantehmg the roasting machine are limited, led to the tube-like Trommelbüge!. This is a perfect sealing of air ducts hardly reach ¹ S against the entry of flue gases. What matters is still very membranous that the gases into the air line and continue into the Reach the drum and thereby exert an extremely harmful effect on the aroma of the processed tobacco, so the temperature that can be reached and the speed of circulation of the air to be heated is also limited with this type of construction.

Avoiding these disadvantages is the purpose of the present publication.

It consists in the fact that between Rlcehniautel and Rüsltronimel of the roasting machine a freely arranged, on the front sides of the Roasting machine so movably mounted Ruhrschlangensystcni is arranged that the

A passage of flue gases into the air line is completely excluded with this arrangement, since the pipe coil, if within the space swept by the fire gases, has only two connection points r , which can be made completely gas-tight in a known manner. The design of the roasting machine is also considerably simpler and clearer than it is the case with the previously known devices.

Furthermore, the circulation can be much faster than 90. this was previously possible. This greatly shortens the roasting process and makes it a significant one greater profitability achieved than could previously be achieved. 95 Fresh air heating device for tobacco roasting machines, machines and the like, characterized by a freely arranged between sheet metal jacket (c) and roasting drum (d) on the 100 _ End faces (c) and (/) of the roasting machine ~ so movably mounted pipe coil system (g) that the pipe coil system, which is longitudinally displaceable in the direction of the drum axis, is pressed towards the front end wall (V) by the pressure of a spring (0) arranged on the rear end wall (f) in order to ensure a secure seal the joint (/>) between the connecting pipe (//) on the cover bracket (11) , which directs the heated air from the pipe-nexangnisystem (ff) into the drum (</) 1 sheet of drawings.
