Definitions
- the invention relates to a method and a device for expansion of food or Consumable items.
- the inventive method and the invention Device for increasing the filling capacity of tobacco material or comminuted Smoking materials serve.
- tobacco material As regards the tobacco material, the term tobacco material or crushed Smoking materials entrippt tobacco leaf, tobacco rib, tobacco stem, each cut or shredded, recycled tobacco and tobacco by-products such as TV and ZHV winnowings be understood.
- the water content is defined as the mass loss of the tobacco relative to the % Moisture content in% in a drying oven through a drying time of 3 Hours at 80 ° C (so-called Salvis moisture).
- This processed tobacco comes as a raw material, called raw tobacco, in the factories for the production of e.g. Cigarettes or others Beverages based on tobacco.
- the processing chain from the green leaf to the raw tobacco leads to a strong shrinkage. This reduction in volume adversely affects the so-called filling capacity.
- the tobacco industry refers to filling as the property with as little mass use nevertheless produce physically stable, solid or hard end products (e.g., cigarettes) to be able to.
- the filling capacity is also defined as the residual volume in relation to the weight in ml / g, which after compression with a 3kg weight in a cylindrical Setting vessel after a 30 second reaction time).
- phase change to gaseous by heat differ essentially by the impregnation / blowing medium and thus by the phase change.
- Examples are the impregnation with CO 2 (phase change fixed to gaseous), the impregnation with fronen / liquefied gas (phase change liquid to gaseous) and the impregnation with highly stressed N 2 (phase change dissolved according to gaseous)
- the variants of the chemical processes differ essentially by the type of gas generating reaction such as decomposition of additives by heat input in the dryer or by adding a further additive to initiate a reaction.
- the type of gas generating reaction such as decomposition of additives by heat input in the dryer or by adding a further additive to initiate a reaction. Examples of this are the impregnation with NH 3 / CO 2 (thermal decomposition solid to gaseous), the impregnation with H 2 O 2 (thermal decomposition liquid to gaseous) and the impregnation with N 2 H 4 / H 2 O 2 (exothermic reaction liquid in gaseous form).
- Impregnation process is usually designed as a complex batch process.
- DE 195 21 243 describes a method and a device wherein in batch mode a closed container is pressurized and the material therein is heated. Of the Upper good-free area is briefly put under increased pressure. By sudden opening of the container, the material is ejected into an expansion chamber at atmospheric pressure. The increased pressure acts as a propellant. The water in the estate evaporates and the estate is expanding.
- DE 195 21168 describes apparatus and method analogous to DE 195 21 243, however the inner container has no holes in the upper good-free area.

- This invention has set itself the task of the above-mentioned disadvantages of the prior art overcome the technique.
- optimal expansion should be effectively possible and with regard to the tobacco material, the mentioned reduction in filling capacity / shrinkage as far as possible undone.
- the invention allows in the tobacco area advantageously not reached Corressteigerache with filling capabilities after expansion, which can be up to about ten percent above the values for usual, so far generally regarded as optimized expansion methods lie.
- the positive effects on the efficiency of smoking article production are enormous in the quantities of tobacco used in industry. In the field of others expandable food and beverages are corresponding benefits.
- the material continuously passes through an area higher Pressure, subsequently an area of reduced pressure and finally an area atmospheric pressure.
- the core principle of the process utilizes the property of gases and vapors of pressure energy to convert completely into kinetic energy by means of a nozzle (extreme case: Pressure reduction up to 0 bar). This extreme pressure reduction succeeds only if at the narrowest point the nozzle reaches the speed of sound or, equivalently, the critical pressure ratio becomes. Under these conditions, a further pressure reduction and thus speed increase in the extended section of the nozzle.
- the invention allows a continuous process, integrable in e.g. a tobacco preparation process without special steps (In particular, integration without previous tobacco discharge is in one Air flow dryer possible). This results in only a small additional expenditure on equipment and additional tobacco preparation process steps such as casing / flavoring are without further integrable.
