2382 .Process for treatment of. Tobacco, a-1 in particular for denikotlation of tobacco »

The invention relates to a method of treatment of tobacco to reduce its content of alkaloids and other undesirable substances, in particular free or bound nicotine, using ammonia and water. . .

Has long "been the joint action of, ammonia and water on tobacco used to reduce the nicotine content of the Reduce tobacco au. It is known that the first marriage of this ■ Substances that nicotine releases from its organic salts (this is mainly in the form of nitrates and Malates naturally present in tobacco) and that the water the nicotine released in this way - as well as the excess ammonia, by the way - is easily removed. .

It has already been suggested; to contact between dsm tobacco and these two substances' in liquid form {for example washing or sprinkling with an ammonia solution followed by rinsing with pure water), or in gas mixture form (leaching of loose, tobacco by a for example by distilling an ammonia solution suitable titer obtained Bampfgeiöischstrom from water and HH *) j or by the successive action of an ammonia solution and water vapor with lower Bring about temperature.

All of these procedures have the same night o that for the discharge of nicotine and the remaining ammonia a much higher weight of water must be used than at This excess would have two major disadvantages. On the one hand, you get at the end of the treatment process a tobacco overloaded with moisture, which must therefore be dried on it sustainably, with it let ensures its durability. On the other hand, the water or the steam - even if their tem-

For the same reason and also because of the. To condition treated tobacco so that its moisture content is in equilibrium with the surrounding atmosphere, after the contact treatment section taking place between the tobacco and water vapor, a Ya M kuum is expediently brought about, which is a hissing (wet) vacuum (More precisely, one understands an absolute pressure which corresponds to the pressure of the water vapor under the prevailing temperature conditions).

To speed up the treatment, the vacuum can be used. that on a contact treatment section tobacco ammonia or Tobacco Waeserdampf follows, through a direct introduction of water vapor in the former case, and of ammonia in the latter Trap to be interrupted.

The tobacco can also advantageously - for example in the container used for treatment - be subjected to pre-moistening under a so-called "classic" vacuum (ie a vacuum _f built up from the creation of a first vacuum and a steam injection with subsequent creation of a moist vacuum, which the Tobacco temperature eneprioht).
