Process for processing tobacco substitute plant parts to a

Tobacco substitute film

The invention relates to a method for processing wood poor or wood-free tobacco substitute plant parts that can be processed using technological methods customary in the tobacco industry smokable tobacco substitute film and a tobacco substitute film produced by this method. Under tobacco substitute plants are all Understood plants that are not tobacco plants.

Tobacco plants contain harmful nicotine and are expensive as well therefore one has lettuce leaves soaked with plant extracts and other nicotine-free plant leaves as well as one soaked in tea extract Paper proposed as a tobacco substitute film. The taste, the burn and the content of minor substances that are beneficial to health of the smoker are of importance, is unsatisfactory in the case of known tobacco substitutes and the one required for further processing The known tobacco substitute films cannot sufficiently achieve elasticity. These are the main reasons, deretvege «from

Except for the well-known tobacco substitute in special cases, at most as Can be added to natural tobacco.

The object of the invention is to provide a method and a film of the to design initially mentioned type so that with the least possible effort, the end product in terms of burn-off and the Further processing is as similar as possible to the natural tobacco prepared for further processing and in terms of aroma or rather The taste as well as the content of secondary substances can be adjusted largely arbitrarily.

The invention is characterized in that a slurry is formed from the tobacco substitute plant parts pre-ground to a grain size of 150 ^ - and smaller and water in a weight-related mixing ratio of 1: 1 to 1: 10, from which a mouldable pulp is then formed by wet milling, which by while mixing is made hygroscopic from 0.5 to 3% of SCMC (sodium carboxymethyl cellulose) capable of binding to and under mixing 1 to 10% of plasticizer substance and in the up to ^l 4% mineral fibers to improve the structure, up to 1% formate salts in order to promote the erosion and to 5 # aromatic and / or pharmacologically active additives are stirred and that then ^ the slurry is spread out to a layer which is then NEN Trock- to a moisture content of 1 to 15% formed on the film and solidified. All percentages are percentages by weight based on the dry weight of the plants, with the exception of the percentages relating to the moisture content, which are based on the dry weight of Poland. The specified grain sizes of ⁿ 150 and smaller than ^{11 are} intended to mean that all grains can pass through a sieve with a passage cross-section of 150 l ** diameter; all other grain size specifications are based on the same definition.

The invention makes it possible, by selecting suitable replacement plant parts which are composed to aromatic mixtures can from the outset have a targeted influence on the composition and thus

to take on the taste and content of minor substances. 3 if one starts from tobacco substitute plant parts that stimulate, stimulate the circulation, stimulate appetite and / or the like in the smoke contain pharmacologically or aromatically active ingredients, then tobacco substitutes can easily be found contains these ingredients. The term "in the smoke" is used here and in the following to mean that it relates to the effect of these components arrives in the smoke inhaled by the smoker.

To achieve or preserve a good aromatic taste and avoid sticky, scratchy taste components, it comes down to careful treatment of the tobacco substitute plant parts and economical use of additives.

According to the invention, the grinding process is gently wet-ground in the last decisive grinding stage. The pre-grinding can be done dry or wet, dry pre-grinding is easier. Preferably, the tobacco plant replacement parts are pre-ground in a first pre-grinding process by directly knitting mechanical cutting edges, beating edges and / or grinding edges to a grain size of 150 ^ and smaller, and then in a second pre-grinding process solely by colliding the coarsely pre-ground tobacco substitute plant particles in a turbulent air stream Grain size of 50 Jx and smaller fine, pre-ground dry and then slurried. The second pre-grinding process can be carried out very gently despite the small grain size of 50yLC and smaller achieved.

Preferably, for wet grinding the slurry, it is driven between the grinding grains of a grinding grain pack, which roll on one another by stirring. In this way, the slurry can be ground to a particle size of 5 μm and smaller without impairment of the aroma due to local overheating of the ground material. The fine grinding of the slurry takes place in a purposeful manner

while simultaneously heating to 70 to 100 degrees Celsius during 15 to 30 minutes duration, because it makes the binding the binders present in some parts of the plant, such as the Example pectins, can be favored. In many cases, that which occurs anyway during the wet grinding process is sufficient for this heating Frictional heat. The grinding grain packing - preferably glass balls with an initial diameter of 2 millimeters - can are in a container in which a stirring tool the pack is constantly stirring. A mill suitable for this purpose is from Austrian patent specification number 280 870 known.

The inventive method is applicable to all types of at least wood-poor plant parts such as grasses, bark, roots, seeds, Leaves, needles, vegetables, herbs, flowers, stems, shoots and root branches and so on applicable to fermented and non-fermented and dried and non-dried plant parts of this kind as long as their smoke does not contain any inadmissible amounts of harmful substances that have not been withdrawn or can be rendered harmless. Examples are lettuce leaves, lettuce ribs, tea leaves, tea stalks, pine needles, Fir branches, rose petals and mixtures thereof.

Poisonous, harmful and / or for other reasons undesirable substances of the plant parts used are best removed the milled slurry or, better still, extracted from the pulp. As examples of such poisonous, harmful and undesirable plant components that are present in some plants and optionally withdrawn from the slurry or slurry are eligible; Atropine, morphine, heroin, and other toxic products. These unwanted plant components can be removed, for example, by steam distillation can be removed at a certain pH value or by extraction with solvents.

Components »that are missing in the plant parts used or are not present in sufficient quantities, such as stimulating, circulatory, appetizing and / or stimulating in the smoke The same pharmacologically active substances and / or sauces, flavorings or aromatic substances can be added to the slurry or stir in the porridge. Examples of pharmacologically effective additives that can be stirred in are: Menthol, nicotine, caffeine, as well as other heat resistant ones Undecomposed volatile substances in the smoke. These additives are expediently dosed so weakly that harmful effects, the go beyond the desired beneficial pharmacological effect, cannot occur. Nicotine as an additive will expediently be dosed so weakly that with the great harmful effects as is not to be expected with natural tobacco.

Possible plasticizer substances are, for example: 70 percent sorbitol, glycerine and diethylene glycol.

If the tobacco substitute plant parts used contain natural binders such as pectin and the like, then these are at least partially broken down and capable of binding by the inventive treatment, in particular during wet grinding to a pulp. This can be supported and thereby NaCMC can be saved by adding chemicals to the slurry or to the pulp, whereby you limit yourself to small amounts, namely no more than 5% based on the dry plant weight used. Chemicals which can be added to the slurry or the pulp to promote the digestion of the binder include, for example: ammonia, ammonium formate, potassium hydroxide, potassium carbonate, polyphosphate. Citric acid and tartaric acid.

example 1

1 kg of raw material consisting of a mixture of 70 % tea leaves, 5 % potato peels, 12 % rose petals and 13% aniseed root tips are cut to a maximum 2 cm cutting size, then in a hammer mill to 150 ^ and smaller and then in an air jet mill to 50 ^ and smaller pre-ground dry.

The millbase obtained in this way is suspended in 4 liters of tap water and the suspension is forced through a constantly stirred glass ball packing. The average residence time of the slurry in the glass bead packing is 10 minutes. The excess heat generated by frictional heat during the drive through the glass ball packing is dissipated by cooling so that the slurry cannot exceed a temperature of 43 degrees Celsius during the grinding process. In the pulp that leaves the glass ball packing, the plant parts are ground to a particle size of 5 / x and smaller, sometimes even to a colloidal size, that is, to a grain size smaller than iyuu. 20 grams of NaCMC as a binder additive and 30 grams of glycerine as a plasticizer are mixed into the paste. Then the slurry is spread on a horizontal steel sheet and solidified by drying to a moisture level of 2% , and then the solidified film is re-moistened by spraying with water vapor to a moisture content of 10 % and peeled off from the steel sheet with a scraper (the moisture values are percentages by weight of moisture based on the ro'-ieritr-3okenyeu'iclit). The film, which is elastic and firm, is then cut into pieces as large as natural tobacco leaves and many of them or mixed with them to produce smokable articles such as cigarettes, cigars, tobacco and the like.
