A smoking machine is described which is capable of smoking cigarettes in large quantities completely automatically. The machine was developed from the smoking machine of BAT type for 30 cigarettes. 30 cigarettes are smoked simultaneously and each puff is drawn from the cigarette individually. The following processes are automatic: the feeding of the cigarettes from a hopper into the smoking head, the lighting and the smoking of the cigarettes, the counting of puffs, the ejection of the butts after a determined number of puffs and the extinction of the butts. The control of these automatic processes is effected electrically. In the case of a deficiency of cigarettes in the hopper or when the operation of the machine is defective, the staff is alerted by means of an automatic control system. The smoke is condensed in a cold trap with a high capacity. The capacity of the trap is large enough to receive the smoke production of five days. The puff profile of the smoking machine is rectangular. The smoking machine can be used for plain cigarettes as well as for filter cigarettes. The length of the cigarettes to be smoked is unrestricted. Any number of puffs per cigarette can be chosen. The conditions of smoking correspond to the CORESTA standard. The dimensions of the machine are small enough to make the machine fit easily in every normal laboratory hood. 8 machines can be supervised by one person. This means that one experienced person could control the smoking of 8000-10 000 cigarettes a day. It is shown that the smoking to a constant number of puffs gives the same results as the smoking to a constant butt length, provided the number of puffs yields the required butt length.
