Description

Process for the manufacture of a smoke or steam product for immediate consumption in a shisha

Field of invention

The invention relates to a new, commercially applicable process for the production of products for immediate consumption in the shisha. It can be smoke or steam products. The differences between smoke and steam products are explained below.

In the following, an extremely flexible multi-component system is described, by means of which numerous variants of flavored smoke and steam products can be quickly produced from a few components, either on the basis of classic tobacco or on the basis of an alternative carrier. In this way, dealers and hookah bar operators can save considerable storage quantities and thus considerable storage costs.

Background of the Invention and Prior Art

Shisha smoking has been gaining popularity in western countries for a number of years. In many cities there are cafes and bars in which the corresponding shisha pipes and the corresponding tobacco are offered.

The shisha is a water pipe that has been known since the 16th century at the latest and first spread to India and large parts of the Arab world. In many Arab countries, the shisha is an integral part of the culture; the common smoking was and is to this day as a symbol of the

Respected hospitality. This culture also arrived in western countries through vacationers and migrants. Structure, components and functionality of the shisha

The structure, the components and the functioning of a shisha can be described as follows. A shisha initially contains a water-filled vessel, the so-called bowl. A so-called smoke column with an immersion pipe is screwed onto it. The smoke column with immersion pipe is screwed onto the bowl. So much water is filled into the bowl that the immersion pipe protrudes into the water after the smoke column is screwed on. The shisha head and a charcoal carrier are placed on the upper end of the smoke column. The shisha head together with the coal carrier is also called the head structure. The hookah head is filled with hookah tobacco (or the alternative carrier material described below. The charcoal carrier has one or more openings for the air flow, which in principle act like a sieve. The screen-like charcoal carrier is filled with charcoal and placed on the hookah head.

Above the water level on the bowl is an opening into which a hose with a mouthpiece can be inserted.

When the mouthpiece is pulled, a vacuum is created in the bowl. This negative pressure causes an air flow that is heated over the coal and then drawn into the bowl over the tobacco or carrier material. The mixture of glycerin and aroma with which the tobacco or carrier is impregnated evaporates and ultimately reaches the consumer's lungs via the smoke column, bowl, hose and mouthpiece.

The difference between steaming and smoking in the shisha

If smoke particles, volatile hydrocarbons or even polycyclic carbons are produced when the ash is burned, it is referred to as hookah smoking. When using tobacco, the formation of smoke is practically unavoidable. If the mist consists only of liquid droplets, then one speaks of shisha steam. The alternative carrier described below allows such vaporization without the formation of smoke particles.

Particularly when steaming, further precautionary measures must therefore be taken to ensure that no ash falls through the sieve onto the alternative carrier and that no overheating occurs in the system.

However, there is a fundamental difference in how tobacco-based smoke products (R) and tobacco-free steam products (D) are used in the shisha.

The smoking product is smoked in a conventional manner. The head is filled with tobacco-based smoking product (R), the sieve-like charcoal carrier is put on and smoking can begin when the glowing charcoal is put on. As the coal burns, ash regularly falls through the holes in the sieve-like coal carrier onto the tobacco. In addition, the coals are changed by a coal boy. When changing the coal with the pointed edges on the tongs, glowing pieces of coal fall through the sieve onto the tobacco. In addition, moving the charcoal on the sieve balances the heat. If the heat becomes too strong at certain points, the tobacco burns too much, causing scratching and pressure in the consumer's throat. When smoking the shisha, charcoal tongs are always supplied so that the smoker can prepare his own charcoal. In all cases, ash always falls on the tobacco and at least volatile combustion materials are always produced. This process is therefore always a "smoking" process in which smoke particles are emitted. If you look at the head after the smoking process (the "session"), the top layer is of the tobacco always black as a sign of the charring of the tobacco.

When consuming the tobacco-free vapor product (D) in the shisha, proceed as follows:

The prerequisite for safe consumption of the steam product is that under no circumstances do charcoal particles or charcoal ash, in particular no glowing components, fall on the carrier material. It is also important to ensure that the carrier is not overheated. It is therefore essential to ensure that the carrier is not in direct contact with the embers or with metal parts that are heated by the glowing charcoal (e.g. the sieve of the charcoal). Otherwise no vaping is possible.

Since the shisha heads differ in size from the inner volume, an amount of carrier material must be selected that ensures that overheating is excluded. The carrier material must therefore not have direct contact with the metal parts of the carrier head or the aluminum foil described below. The ideal distance between tobacco and heated metal has proven to be 2-3 mm.

Various accessories are offered to support the charcoal. Sieves, chimney tops or charcoal boxes etc. All parts are built so that you have openings downwards and you can see the tobacco through the openings. If the glowing coal is now placed on the carrier, of course burned and also moved back and forth, hot ash inevitably falls through the holes. As a result, ash or glowing coal particles always fall on the tobacco or carrier if no precautions are taken. To prevent this, a commercially available aluminum foil is first placed or pulled over the shisha head filled with carrier material. The aluminum foil is chosen a little larger than the upper opening of the hookah head and is then pressed all around the hookah head so that the aluminum foil clings to the hookah head. Then 5 to 20 openings are pushed into the aluminum foil with a pointed object. The openings should have a diameter of approx. 1-2 mm. Then the carrier for the coal is put on. As described above, the carrier has one or more sieve-like openings at the bottom. The carrier is placed on the aluminum foil in such a way that you can no longer look at the tobacco visually. The holes formed by piercing the aluminum foil are therefore not under the holes in the portafilter. This ensures that no glowing charcoal particles fall on the tobacco. The passage is still guaranteed. So the steaming pleasure can begin with. Alternatively, you can proceed as follows:

First, as described above, an aluminum foil is placed over the hookah head filled with carrier material and pressed all around the filled hookah head. Then the coal carrier is put on. As described above, the coal carrier has one or more sieve-like openings. Use a pointed object to pierce the aluminum foil through the openings in the carbon carrier. The holes in the aluminum foil (diameter approx. 1-2 mm) are therefore exactly below the sieve-like openings in the carbon carrier. Then the foil and the charcoal carrier are turned slightly against each other so that you can no longer look at the tobacco visually. The holes formed by piercing the aluminum foil are no longer under the holes in the portafilter. This also ensures that no glowing charcoal particles fall on the tobacco. Preparation of the tobacco

A special, very "moist" tobacco is generally used for the shisha, which is difficult to ignite because of its "moisture" properties. The main humectant used for water pipe tobacco is glycerine. Depending on the recipe, honey or all kinds of sugar and flavors are usually added to this. There are hundreds of flavors that can be added, but additions to the basic flavors of menthol, mint and mint oil as well as eucalyptus are very popular at the moment. Classics that are popular everywhere are Ice Grape, Doppelapfel, Ice Apple. The flavoring substances are usually dissolved in propylene glycol.

The term "moisture" is at least partially misleading because "moisture" is commonly associated with water. The "moisture" of the shisha tobacco, however, is based on its glycerine content. If the aroma is mixed with the glycerine, honey, sugar, the singular is molasses and the plural molasses. Each manufacturer has its own recipes, including through The different qualities of the tobacco types, i.e. the ratio of leaves / ribs, the recipes and mixing ratios are different, but it can be said that the ratio of tobacco to molasses is typically 10-15% tobacco to 90-85% molasses.

For the conventional preparation of shisha tobacco, the 10-15% dried tobacco leaves are placed in a stirred kettle and the complete flavored molasses, i.e. 90-85%, is poured onto it. Then the tobacco is stirred. How long is stirred depends on the speed and shape of the stirrer. But it can be said that the stirring process should not take longer than 5-10 minutes. When stirring, the dry tobacco learns a mechanical load and is crushed as a result. The stirring only causes a uniform external wetting of the tobacco with molasses. Glycerine and other additives (such as honey) only begin to be absorbed after a few days. The tobacco leaves are dried and the pores take a while to open.

The stirring time must be limited in time due to the shredding of the tobacco leaves, otherwise only a tobacco pulp is obtained, which consumers reject for various reasons. If the tobacco leaves are too crushed, the small leaves fall through the holes in the head into the water in the bowl. On the one hand, it looks unsavory and, on the other hand, there is a significant loss of quality because the tobacco leaves also end up with the aromas in the water.

The tobacco is then stored in containers or barrels so that the molasses can move in. By regularly stirring the tobacco or turning the barrels, the tobacco can only be consumed or smoked after a few weeks.

The process of drawing in can be accelerated by heating the glycerine. However, moistening with warmed glycerine also takes at least twelve to 18 hours. The boiling point of glycerin is around 290 degrees Celsius, but the glycerin must not be heated to more than 120 degrees Celsius, as otherwise the hot glycerin will severely damage the tobacco leaves and the tobacco can no longer be used.

One problem with the preparation shown is that it is impossible to provide finished hookah tobacco at short notice. This production method inevitably always produces quantities of tobacco that cannot be sold and consumed immediately and therefore long stocks bring yourself. Sometimes the flavors in demand change at short notice, flavors are typically also seasonal. In summer, citrus flavors are in demand, fresh and light. Creamy aromas in winter or Christmas aromas such as baked apples or cinnamon and biscuits. The flavors also differ from region to region. In the various shisha bars, it also depends on the flavor directions that have been introduced. Therefore, not only is great flexibility required in the production of hookah tobacco, but also the possibility of being able to make flavored hookah tobacco available at short notice in order to avoid bottlenecks in certain aromas.

Another problem is the large amount of capital tied up for the dealers due to the need for warehousing.

These problems are overcome by the present invention.

State of the art

EP 2957183 A1 describes microparticles obtained from tobacco plants (average particle size <30 μm) as an additive to cigarettes to improve the smoke aroma.

US 2008/0000488 A1 describes the use of cigarette rolling paper ("cigarette rolling paper", in Germany called "rolling papers") as a base material for tobacco-free smoking material. Such cigarette paper contains numerous fillers and fire salts in order to match the flammability of the paper to the flammability of tobacco. For technical reasons, the cigarette paper is also very poorly absorbent.

DE 202019 103 342 U1 describes aerosol-forming substances for use in a water pipe, containing honey or sugar cane molasses.

WO 2014/020337 A1 describes the production of an extract from tobacco plants. Principles of the invention and preferred embodiments

The present invention teaches a component system for the manufacture of ready-to-use smoke and steam products.

The invention consists of the components shown in FIG. 1, which are further described below.

Dry raw tobacco (RT dry), preferably with very little nicotine. The most suitable for use in the shisha is the German Virginia, which contains the least amount of nicotine and is honey-yellow in color.

Carrier (T-dry) made of chemical-free crepe paper without any additives, i.e. pure cellulose.

Moisturizer (B1) for dry raw tobacco (RTdry) or for the carrier T dry. Components can be:

Glycerine, water and optionally propylene glycol.

In an optional embodiment, namely for pre-moistening the alternative carrier (T-dry), the moistening agent (B1) can also contain tobacco aromas and / or nicotine.

Moisturizer (B2) is a liquid product for moistening and flavoring. Components can be: aromas, glycerine, water, propylene glycol. Applied to pre-moistened tobacco T, immediately consumable shisha tobacco (R), known as a smoking product, is produced. The wetting agent B2 can optionally also contain admixtures of sugar and / or honey. Alternatively, the humidifying agent (B2) can also be applied to an alternative carrier substance (TS), so that a vapor product (D) is created.

Pre-moistened raw tobacco (Dfeucht) is created by adding the moisturizing agent (B1) to the dry raw tobacco (RTtrocken) will .

Pre-moistened carrier material (TS _moist ) is created by adding the moisturizing agent (B1) to the carrier material (T Strocken).

In retail stores or in hookah bars, only pre-moistened raw tobacco (T moist), pre-moistened carrier (T S moist) and various humectants (B2) need to be offered and kept in stock for this purpose.

The consumer can purchase the components pre-moistened raw tobacco (T moist), pre-moistened carrier (TS moist) and one or more moistening agents (B2) in stores. If the consumer (B2) _{pours (T moist} ), he receives a tobacco-based smoking product (R). But if he pours humectant (B2) on (TS _moist ) then he receives a vapor product (D). Both products can be consumed immediately. The difference between smoking and vaping has already been explained above.

Process for moistening dry raw tobacco (RT)

In the context of the invention it has been found that, surprisingly, the moistening process of the raw tobacco with glycerol can be accelerated considerably if the dried raw tobacco with a composition containing 50 to 90% glycerol, 5 to 25% water, 0 to 30% propylene glycol via a Period of one to six hours at a temperature of 18 degrees to 120 degrees Celsius. The mixture of raw tobacco and first composition contains 10-15% raw tobacco and 85-90% of the first composition.

The invention therefore also relates to a method for preparing raw tobacco, in particular leaves of whole raw tobacco, for later use in shisha pipes, characterized by bringing dried raw tobacco in leaf form into contact with a composition containing 50-90% glycerol, 0-25% water, 0-30% propylene glycol, over a period of 1-6 hours at a temperature of 18 ° C to 120 ° C in a mass ratio tobacco: composition of 10:90 to 25:75 as well as the necessary glycerine-containing compositions.

A homogeneous composition containing 50 to 90% glycerol, 0 to 25% water and 0 to 30% propylene glycol is essential for the described method according to the invention.

It goes without saying that the sum of the components must be 100%. A preferred composition consists of 85% glycerin and 15% water. It has been found that the moistening process is accelerated the more the warmer the moistening agent should be and the more water it contains. As stated elsewhere, however, the temperature must not exceed 120 °, the water content should not exceed 25%, it is preferably around 15%.

In the context of the present invention it has been found that the use of tap water in the composition described is suitable for quickly moistening dried raw tobacco in the desired manner. Surprisingly, however, it has been found that the shisha smokers often do not "taste" the tobacco obtained in this way. It is reported to be indigestible, accompanied by unpleasant scratching and pressure in the throat. This disadvantage is overcome if instead of tap water, distilled or preferably double-distilled water is used is used.

By using a composition of 50 to 90% glycerine, 5 to 25% (preferably double-distilled) water and 0 to 30% propylene glycol, preferably 85% glycerine and 15% Water is a shisha tobacco, which is felt to be extremely pleasant and digestible.

In the context of the process according to the invention, the humidifying agent (B1) is first added to the dry raw tobacco (RT dry). The mixture is preferably set in motion carefully. Too fast stirring should be avoided so that the tobacco leaves are not damaged (see above). The process can be carried out at room temperature; the process is preferably carried out at an elevated temperature (> 50 ° C.). It has been found that the temperature must not exceed 120 ° C.

The tobacco leaves, which are typically yellow when dry, change their color to medium to dark brown as part of the moistening process. This color change can be used to read when the tobacco is continuously moistened. As long as there are yellow spots in the tobacco leaves, the moistening is not sufficient. The humidification process takes four to six hours at room temperature; at 120 degrees Celsius, sufficient humidification is achieved after just one hour. A further increase in temperature above 120 degrees Celsius leads to the destruction of the tobacco leaves, which is undesirable.

For moistening within the scope of the method according to the invention, usually 10-15 grams of raw tobacco are mixed with 85-90 grams of the moistening agent B1. It becomes a with

Glycerine pre-moistened tobacco (Tf _eU cht) is obtained as an intermediate product, which can be briefly flavored as described below, so that the desired smoking product (R) is created. Description of the humidifier (B2)

It has also been found that the pre-moistened tobacco (Tf _eU cht) produced as described above can be briefly flavored with the second moistening agent (B2) described below and the tobacco is given the desired residual moisture. Component B2 contains 30 to 82% glycerine, 10 to 30% water, 3 to 30% propylene glycol, and flavorings. The end product (R) typically contains 4-16%, preferably 8-13%, flavoring substances.

The flavorings are commercially available; they are preferably used as a solution in propylene glycol.

The reaction of the pre-moistened tobacco (Tf _eU cht) with the moistening agent (B2) can be done, for example, at room temperature. Component B2 can also be preheated to up to 60 degrees Celsius. It should not be heated above 60 degrees, because then the volatile components turn into steam and the aroma undergoes changes in taste.

The advantage of the method according to the invention is the immediate availability of the desired smoke product (R) ready for consumption. The consumer (or operator of a corresponding hookah bar) can very quickly prepare the tobacco (Dfeucht) that has been moistened in stock into a consumable hookah tobacco, as a smoking product (R). The moistened raw tobacco T _moist absorbs the component (B2) immediately and completely and is immediately ready for consumption. Optionally, other substances can be added immediately before smoking, e.g. nicotine shots and / or CBD, within the framework of the legal provisions.

The components are matched to one another in such a way that when the components are mixed, a smoke or steam product that can be consumed immediately and of a significantly better quality is created than the conventionally manufactured shisha products described above and without storage or maturing time. The better quality can be derived from the following points:

- The flavors are mostly heavy oils. In a large-scale production where large quantities are produced, everything is put into a stirred tank and mixed. As soon as you stop stirring, the heavy aromas begin to settle down. When the tobacco is withdrawn in portions, it is inevitable that the tobacco first withdrawn at the top has a lower aroma concentration than the last tobacco withdrawn from below. This is inevitable because large containers cannot be stirred in such a way that the flavor distribution is homogeneous during the filling in portions. The quality of the shisha tobacco can therefore fluctuate greatly within a batch: This explains the reports from customers on the Internet that warn of certain batches of tobacco, while other customers do not express any complaints.

- In the production according to the invention described herein, precisely the amount of aromas per portion that is desired or specified is weighed and filled. You always have the same taste quality for each unit.

- Additions of water surprisingly lead to an improved absorption of the glycerine into the tobacco.

Additions of up to 25% water do not affect the smoking behavior of the tobacco. The "taste" of the smoke is not changed either.

The addition of propylene glycol also surprisingly leads to an improved absorption of the glycerol into the tobacco. The propylene glycol vaporizes almost as much like glycerin. Because you like these steam clouds when consuming shisha, it is suitable for mixing.

Differentiation from the state of the art

Instructions for moistening finished hookah tobacco with molasses and / or water are circulating on the Internet. Some of the "molasses" used for this purpose are also described as containing water. In contrast to the present invention, this involves (re-moistening) older, dried out tobacco that was originally already moistened such "rewetting" is obtained, these procedures do not fall within the scope of the invention described herein.

Use of an alternative carrier

The invention allows yet another embodiment by using an alternative carrier (TS) which is not made from tobacco. An excellent tobacco-free vapor product (D) can be produced with this.

The component TS is a shredded crepe paper which can be used as an alternative carrier for the tobacco-free use described in a shisha pipe. In the context of this application, special, chemically unstressed crepe paper is used as an alternative carrier material (T S). The initially dry carrier material (T Strocken) is first mixed with the moistening agent (B1) so that a pre-moistened carrier material (T S moist) is obtained as an intermediate product.

The pre-moistened carrier material (T S moist) becomes an immediately consumable vapor product (D) by applying the above-described second moistening agent (B2).

According to the invention, a special crepe paper is used as the carrier material. This crepe paper shouldn't come with

Chemicals (e.g. to improve tear resistance or bleaching) and should be food safe according to BfR 36, 36/1, 36/2 and FDA. The crepe paper must also not contain any fire salts. The crepe paper is shredded and produced as paper wadding or, for example, in strips 2-5 mm wide with a length of 1-6 cm. In this way, the crepe paper can be easily portioned as a carrier. The crepe paper used as a carrier has the following properties:

Weight per unit area: 30-60 g / m ² , preferably 35-56 g / m ² , in accordance with DIN EN ISO 536

Thickness (801 layer): 10-12 mm, preferably 11.0 mm, according to DIN EN ISO 534

Breaking strength, lengthways: 10-35 N / 15mm, preferably 32 N / 15mm, according to DIN EN ISO 1924/2

Breaking strength, transverse: 20-25 N / 15mm, preferably 22 N / 15mm, according to DIN EN ISO 1924/2

Wet breaking strength, lengthways: 5-7.5 N / 15mm, preferably 6.7 N / 15mm, according to DIN EN ISO 1924/2

Wet strength: 1200-1300 mm water column, preferably 1250 mm water column, according to the Melitta method

In the case of the vapor product (D) with cellulose-based crepe paper as an alternative carrier (TS), nothing has to be taken into account with regard to the drawing in of liquids. The alternative carrier takes up both the humidifying agent (B1) and the second humidifying agent (B2) within seconds. Due to these suction properties of the alternative carrier (TS), it is theoretically also possible to convert the dry carrier substance (Tdry) into a vapor product (D) in just one process step using a humectant (B2), as shown in FIG. For this purpose, the moistening agent (B2) may have to be adjusted in terms of its composition, since otherwise the amount of flavoring in the end product may be too high.

The end product ready for consumption, namely the tobacco-based smoke product (R) or the tobacco-free vapor product (D), typically contains 4-16%, preferably 8-13%, flavoring substances. Optionally, the end products can be enriched with additives, such as vitamins. It is also possible to add cannabinoids, especially CBD.

The tobacco-free vapor product (D) can optionally also contain nicotine and / or tobacco flavors. For this purpose, nicotine and / or tobacco aromas can be added to the carrier either as a component of the humectant (B1) or as a component of the humidifier (B2). It is also possible to add nicotine and / or CBD immediately before vaping by adding "shots", whereby the nationally different, legal provisions must be observed.

The carrier substance is steamed in the same shisha head as tobacco is smoked. However, the instructions described above must be followed.

Shishas with electrical heating can also be used in this embodiment.

By observing the instructions described above, it is ensured that only components of the humidifier are brought into the gas phase by means of (B2). This embodiment uses the resulting steam, which consists only of glycerine, water and propylene glycol, which contains the gaseous aroma components. For this embodiment, trademark protection for the designation "AROMING" was applied for at the DPMA.

Since no tobacco is used in AROMING, the resulting vapor contains neither nicotine, nor tobacco aromas or other tobacco components, unless these are added.

In summary, it can be said of this embodiment with an alternative carrier that the carrier TS always immediately absorbs liquid additives such as the humidifying agent (B1) or the humidifying agent (B2). With the purchase of the humidifier (B2), the customer can decide whether he wants to smoke or vape in a health-friendly way. It has been proven that the carrier substance (TS) does not develop any substances that are harmful to health when used as intended.

The particular advantage of the system according to the invention is that the pre-moistened carrier (TS moist) _{can be offered in the same container sizes as an alternative to the pre-moistened tobacco (T f eU} cht), which can each be mixed with the same amount of moisturizing agent. The consumer therefore does not have to purchase different types or quantities of humidifying agents for use as a smoke or as a vapor product. The consumer can thus stay true to his habits when switching from smoking to vaping. The invention also enables the consumer to use either tobacco or a carrier, so that the consumer can find out that the aromas taste better on the carrier than on tobacco because the products of combustion are no longer consumed. The switch from smoking to much healthier vaping is made much easier.

Due to the similarities of pre-moistened carrier (TS moist) pre-moistened tobacco (T f _euc ht) in optics, feel and use, these can also be made available and used as a mixture. The mixing ratios are arbitrary: Mixing ratios T moist: TS moist of 90:10, 75:25, 50:50, 25:75, 10:90 are possible. By

Using such mixtures, avid smokers can gradually be weaned from tobacco. Objects of the invention
