Method of and apparatus for processing exhausted air in tobacco processing plants

Apparatus for processing contaminated air which is laden with solid impurities, including reusable tobacco particles, during passage through a machine for the making of smokers' products, comprising means for at least partially decontaminating said contaminated air, including means for separating at least the reusable tobacco particles from said contaminated air;

• and means for introducing the separated reusable tobacco particles into a machine for the making of smokers' products, including means for segregating reusable tobacco particles from other solid impurities.

A method of processing contaminated air which is laden with solid impurities, including reusable tobacco particles, during passage through a machine for the making of smokers' products, comprising the steps of at least partially decontaminating said contaminated air including separating all of the solid impurities therefrom;

• thereafter segregating reusable tobacco particles from other solid impurities;
• and thereafter introducing the segregated reusable tobacco particles into at least one machine for the making of smokers' products.

Apparatus for processing contaminated air which is laden with solid impurities, including reusable tobacco particles, during passage through a machine for the making of smokers' products, comprising means for at least partially decontaminating said contaminated air, including means for separating at least the reusable tobacco particles from said contaminated air;

• means for conveying said contaminated air in a predetermined direction along a predetermined path past said separating means;
• means for admitting into said path at least one stream of air, which contains solid impurities at least substantially free of reusable tobacco particles, upstream of said separating means;
• and means for introducing the separated reusable tobacco particles into a machine for the making of smokers' products.
