Abstract

The present invention relates to a method for producing a tobacco product which can be sucked. In order to develop a novel tobacco product which can be sucked, the following processing steps are suggested that a mixture prepared from a tobacco fragment and starch used as an adhesive and an additive or a product containing the starch is prepared, the mixture is impacted and plasticized in an extruder through the addition of heat and mechanical energy, water vapor under the pressure is extruded to pass through the mixture, and accordingly, a channel is formed. When the mixture leaves the extruder, the plastifying mixture which becomes porous because of the airflow channel is expanded and foamed because of the reduction of the temperature and the pressure, continuous spongy cylindrical bars are formed in the mode of hardening, and the plastifying mixture is cut off according to the needed length.

Description

The method of the tobacco product that production can be aspirated

The present invention relates to the method for the tobacco product that a kind of production can aspirate.

Disclose a kind ofly by handling the method that tobacco is made the crimped fibre section again in DE-3339247C1, wherein, tobacco end and/or tobacco waste are processed into a kind of mixture of plasticization with binding agent and doping in case of necessity.In extruder, be configured as the thin-walled hollow body of continuous expansion by the cylindrical bars of compositions of mixtures of plasticizing, and be divided into the curling intermediate products of wire, this intermediate products and then be separated into curling segment of fiber.

DE-3819534C1 discloses a kind of by handling the method that tobacco is made the reconstituted tobacoo section again.Wherein, pulverous tobacco waste and/or tobacco end is with binding agent and doping mixing in case of necessity, and with mixture plasticising in extruder of this acquisition like this.The mixture of this plasticizing is through exactly isometric flow process, is divided into the machinery of even number/consistent cylindrical bars of geometry.Per two adjacent consistent bars are rolled into a thin slice band jointly, then it are cut into the thin slice section.The plasticising of mixture in extruder is carried out under the condition of 90 to 120 ℃ of temperature and pressure 50 to 100 crust.The diameter of cylindrical bars is 2 to 7 millimeters.

In DE-4005656A1, introduced the method that the bigger filling power manufacturing of a kind of usefulness contains the thin slice of tobacco.Wherein, raw material are by the NMF of the tobacco of about 86-98% percentage by weight, about 1-6% percentage by weight and the binding agent of about 1-8% percentage by weight, and mix in 80: 20 to 60: 40 moisture ratio water mixing.The raw material of this humidity pushes from about 30 ℃ to 160 ℃ with temperature profile to the situation of about 200 bar from about 10 at pressure in extruder then, and presses from a nozzle that is provided with the outlet seam, thereby forms reconstituted tobacoo.From both sides heat intensive reconstituted tobacoo, therefore consist of basically air-locked cover layer at reconstituted tobacoo then.By further heat supply consumingly, the moisture that contains in the reconstituted tobacoo between cover layer vaporization, thus produce the air bubble-shaped cavity.

The objective of the invention is to develop a kind of novel tobacco product and a kind of method of producing this tobacco articles.

Be issued in the situation of implementing following process steps by purpose of the present invention:

A) make a kind of by tobacco chippings and the mixture that forms as starch or the amyloid goods of binding agent and additive;

B) this mixture is by adding heat and mechanical energy compacting and plasticising in extruder;

C) wherein, the steam that is under the pressure is extruded by mixture, thereby constitutes passage;

D) when leaving extruder, this plasticizing, owing to there being gas channel to become the mixture of porous, expand and foam because of the reduction of temperature and pressure, be hardened to the cylinder bar of continuous porous, and length is on demand cut off.

The passage that produces by in mixture, introducing steam, with vertically and the form of radial passage be kept in the bar of extruding.The process that takes place this time in suction is the same with the tobacco rods with conventional method system, and difference is, the air of burning usefulness is not that the space in the tobacco of chopping sucks, but the air duct suction by having hardened.Yet also have such gas permeability by the bar that the present invention makes, namely combustion air sucks by the cross section of bar and the length of bar equably when smoking, and the draw resistance that is wherein caused by bar is no more than a higher limit.

Can adopt starch natural and/or improvement as binding agent, the share of binding agent preferably is about 15% percentage by weight.

Can add NMF as additive, for example glycerine, molasses and/other absorbent materials.

In addition, adopt combustion improver, the carbonate or the wetting agent that for example are used to produce the organic acid of grey white fire (Wei β brand) and/or improve aura ability (Glimmfaehigkeit) as additive.

At last, also adopt flavoring essence and/or flavouring as additive, for example by aromatic (Aromapraekursor), extract and the steam distillation water of the ripe leaf system of other plant different from tobacco.

Additive also preferably biology be the basis laminar additive.In order to accelerate the processing in extruder, can add polyvinyl alcohol (PVA) or Pioloform, polyvinyl acetal (PVAC) in the mixture.Therefore obtain the mixture that a kind of better foaming has favorable elasticity/flexibility.The best occupation mode of relevant PVA can be consulted the explanation in DE-4008862C1.

By the present invention, additive also can be used the additive by genetic engineering product system.

In order to generate be used to aspirating essential passage, water vapour pressure is elected 50-120 bar, preferably about 80 bar as.

The tobacco chippings that is used for mixture can be made by shredding ripe tobacco leaf, but also can be the chip that produces during traditional tobacco is processed.In this case, tobacco chippings preferably adopts about 3 to 5 millimeters of screen size.

Commercial current packaged one-tenth cured tobacco has passed through a time-consuming biochemistry evolution: also just begin down on the farm to decompose in tobacco before the tobacco leaf harvesting, the harvesting back is along with the jaundice of fading gradually, drying and fermentation continue to decompose.Ripe chemical reaction course depends primarily on dehydration as far as possible slowly.Having under the life state during beginning, starch that concentration is higher and albumen water content up to the situation of about 80% percentage by weight under hydrolysis, and be converted into soluble sugar and nitrogen compound.Less than 80% o'clock, the enzyme that causes these processes became non-activity in water content; Begin to take place so-called leaf death (Blatt-Tod) this moment.Therefore, in order to make it full maturity, wish in 100 hours, to carry out drying; In this time course, temperature is brought up to 80 ℃ from 32 ℃, and under the situation that increases ventilation gradually, relative air humidity is reduced to 10% from 80%.

Because tobacco leaf is remained on natural climate lower time, just extremely rare the obtaining reliably of this condition is so common this processing can only be carried out in the environment of control is arranged.Should be readily appreciated that in addition, more little and overstepping the bounds of propriety the loosing of the surface area of leaf material to be processed and volume, the effect of artificial best maturation condition is more good.

Be familiar with as starting point take this now, by the present invention suggestion, for making that tobacco chippings for said mixture adopts and chopping unseasoned tobacco leaf still, so that then in the good bar of extruding, that is in the finished product of almost making, implement the slaking of tobacco.For this reason, the bar section of making by the present invention ventilate and air-conditioned environment in carry out temperature, humidity processing, that is leave in the ventilated container in the air conditioning chamber.In this case, the final moisture content that the processing of this temperature, humidity is performed until in bar is, under about 50 ℃ condition approximately from 10 to 13%.Under this state, just can change the last production phase over to.

Under the condition of 20 ℃ and air humidity 60 to 75%, the bar section forms so-called " slaking (aging) " after depositing and surpassing about 0.5 to 2 year.Just can carry out finished product packing afterwards.

Advantage by this method of the present invention is that the processing of steam can play an important role to the tobacco maturation.In processing method, can take full advantage of also but then higher native starch content.At last, the method discloses this possibility, that is, and and whole plant and the leaf of being not only it is only having harvesting in the situation of moderate maturity, chopping and processing by the process of the inventive method then.Therefore can also advantageously utilize to soak the more water storage that the form of swollen water exists in whole plant.

Adopt this new method in fact can with the tobacco full mechanization produce fully novel cigarette finished product.
