Description

Process for the manufacture of smoking preparations. The one during the war The tobacco shortage caused by the blockade had led to the tobacco being thrown through rhöste to replace tobacco-like plant leaves. The blockage no longer exists, the tobacco threatens to become prohibitively expensive, so that with the possibility it is to be expected that one will return to tobacco substitutes out of economic hardship. This is the purpose of the present invention.

According to this experience tobacco-free foliage and foliage-like parts of plants a preparation through which they are healthy and tobacco-like Properties obtained so that they can be used even in the complete absence of real tobacco leaves if not equivalent to real tobacco, for the smoker it is modest Claims become palatable and decidedly more tasty than those in war in many cases offered substitutes.

For this purpose, the yellow, arid foliage to be used becomes first Treated with steam of more than roo ° until it is sterile and at the same time is freed from substances that taste unpleasant when smoked and develop smelling fumes. Leaves taken off green will be useful before steaming first a fermentation (fermentation) process, similar to that of tobacco leaves applied, subjected and dried. If for similar purposes the one hand one Twenty-four hours of boiling, on the other hand again a mere treatment with tepid Steaming is prescribed, so the first goes far too far, the second long not far enough. # In the first case, there is little more than pulp left over, in the. second, eliminating unwanted flavorings is out of the question.

The moderately moist, but treated in the manner just described Not wet foliage is either by drying interrupted at the right time to a moisture content suitable for further treatment (about 2o percent) brought or, if further processing is to take place later, @ "first completely dried and at a suitable time by moistening to the mentioned water content brought.

The further treatment consists of "making a sauce" with one of the real ones Tobacco, mainly lye obtained from tobacco dust. The tobacco waste is made with water leached as much as possible on a warm or cold route, but with temperatures which could destroy fragrances, for example, are to be avoided. So far is reached for boiling, this has to be done with negative pressure. The lye will Thickened for the sake of durability (avoiding the formation of mold). That For the reasons just given, thickening takes place under negative pressure.

The treatment of the leaves with the tobacco liquor can be done in different ways Way done. Either you evaporate the lye and pass the vapors through loosely piled leaves, possibly in motion, whereby one for To protect the fragrances, it is advisable to use negative pressure, or to sprinkle it the Leaves with the lye or you can dip it in the lye. In the first case scored a uniform and economical enforcement of the good with the active ingredients the lye and a mild product. In the other embodiments, it arrives with less economical consumption of lye you can use a more powerful smoke, because the more difficult to evaporate constituents of the lye also get into the leaves.

The foliage treated in one way or another with the lye Finally, it is useful in the case of negative pressure, but in any case if higher pressure is avoided Temperatures that could damage the fragrances, dried. possibly stored and processed.

Exemplary embodiment Green, picked or already yellow, fallen cherry tree leaves of sweet and sour cherries are subjected to a fermentation process similar to that used in real tobacco, whereby it must be avoided that the leaves remain exposed to fermentation-producing bacteria during the rather strong self-heating for too long. Depending on the months following the harvest, the weather will be dry or wet, the process will be completed more quickly or more slowly. The leaves, which have turned dark brown in color, are now steamed for 30 minutes in an iron steamer with a capacity of 30 kg, roughly in the manner of the Henze steamer, with direct steam at about two atmospheres pressure, while at the same time water or Tobacco liquor can be made to evaporate. After the indirect and direct steam has been switched off, the still hot kettle is exposed to a vacuum of about 600 mm for a period of ten minutes with the help of a vacuum device. After cooling for a long time, but at least one hour, the almost dry leaves are removed. If used immediately, it is evenly moistened with a tobacco liquor about 10% thick using a spray device. To avoid the formation of mold, the tobacco liquor is produced either by sterile dissolving of tobacco extract that has been thickened in a vacuum, 40 'trees strong, with water or by hot leaching of tobacco waste with water to the required strength. For a stronger effect, it is advisable to soak the sterile material in tobacco liquor from -8 to 10 ° Baume, whereby the duration of the action can be extended from 30 minutes to 6 hours. Pressing and rapid drying of the wet leaf material to the moisture required for the tobacco substitute cutting machine, expediently with the aid of a drying apparatus that avoids temperatures higher than 55 to 60 ° C, for example in the form of a belt dryer, ends the processing according to the aforementioned process.

Of the many possible mixtures of leaves with one another, taking account of the taste requirements, the following may be given ; o parts of cherry tree leaves, 2.5 - apple tree leaves, 15 - linden tree leaves, 15 - walnut leaves, - pear tree leaves, 5 - sweet chestnut leaves, a - horse chestnut leaves, i - rose petals ioo parts mixture. The foliage mixtures treated in the manner described above, which incidentally have to be mixed thoroughly beforehand, can of course be added by adding leaves of a wide variety of herbs, e.g. B. Jerusalem artichoke, tomato, sunflower, nettle, ribwort, sweet clover, peppermint, spearmint, gentian and thyme, as well as other hobbies can be varied in taste. It is advisable to avoid bitter, scratchy and saliva-contracting plant substances such as hops, coltsfoot, sorrel and similar in larger quantities or entirely.
