Definitions

• the invention relates to a method for increasing the Fillability of tobacco materials, e.g. sliced Tobacco leaves, ribs or vegetable tobacco additives with cell structure by treatment of 8 to 16% by weight Starting moisture having tobacco material with a Nitrogen and / or argon existing treatment gas at Press from 50 to 1000 bar in either an autoclave or in a cascaded circuit in several autoclaves and subsequent thermal aftertreatment of the discharged tobacco material after decompression.

• Starting moisture having tobacco material with a Nitrogen and / or argon existing treatment gas at Press from 50 to 1000 bar in either an autoclave or in a cascaded circuit in several autoclaves and subsequent thermal aftertreatment of the discharged tobacco material after decompression.
• the tobacco expansion with inert gases under high pressures which is also known as the INCOM blowing method, has its Advantages over the pressure treatment of tobacco with Carbon dioxide, ammonia or volatile organic gases and is shown, for example, in US 4,289,148 known, according to which tobacco material with a humidity of over 20 Wt .-% at working temperatures in an autoclave between 0 and 50 ° C is treated.
• the pressure reduction takes place within 0.5 to 10 minutes and in the examples given at 1.3 minutes, after which the discharged tobacco of a thermal after-treatment e.g. subjected to saturated steam and inflates.
• DE 34 14 625 C2 discloses a cascade method, according to which by cooling the treatment gas before the application of the reactor, cooling of the autoclave or use of a supercooled and liquefied treatment gas low impregnation temperature of the tobacco becomes.
• the Pressure reduction times are 0.5 to 10, in particular 1 to 2 Minutes.
• the minimum temperature of the discharged tobacco should be below 0 ° C.
• Analog are also according to DE 39 35 774 C2 at a Cascade - like inflation by circulation of the Treatment gas through a cooler the required achieved low impregnation temperatures of 25 or 45 ° C.
• the invention is based on the object, the previous Improve INCOM procedures and independent of elaborate cooling measures equal good or better To achieve Blähgrade.
• the pressure reduction of the respective Maximum pressure up to the pressure of the holding level in one Interval from 20 seconds to 5 minutes, during the reduction of the residual pressure in an interval of 3 Seconds to 3 minutes is performed. Furthermore, it is to achieve the invention Tabakaustragstemperatur appropriate that the Temperature increase by a holding time, by a circulation of the residual pressure gas via a Heat exchanger and / or by overflow of heated gas caused by another autoclave.
• the High pressure treatment or the sequence off High pressure treatment and thermal treatment several times the same tobacco material.
• the laboratory device for thermal aftertreatment of Tobacco consisted of a permeable conveyor belt or Wire cloth at a speed of about 5 cm / s was operated.
• the guided between baffles Tobacco fleece was under an approximately 160 mm wide steam nozzle with slit-like outlet opening of about 8 mm with about 10 kg / h of saturated steam aftertreated.
• Below the Conveyor belt opposite the steam nozzle was a Dampfabsaugvorraum.
• the thus treated tobacco samples were spread in shallow dishes and conditioned at 21 ° C and 60% relative humidity.
• T A is the discharge temperature of the high pressure treated tobacco.
• test 1 two holding stages of 2 min each at 400 and 100 bar were used in the pressure reduction and in tests 2 and 3 only one holding stage of 2 min or 4 min at 50 bar.
• Comparative Experiment No. 4 the pressure reduction took place directly, ie without a holding stage in a pressure reduction time of ⁇ 1 min.
• Example 2 Analogously to Example 1, the high-pressure treatment was carried out with 150 g of tobacco at a working temperature of the autoclave of 40 ° C. During the pressure reduction, a holding stage of 2 minutes at 50 bar was applied to experiment No. 5 and during the holding time the gas was circulated by means of a circulating pump through a heat exchanger with a temperature of 80 ° C. The gas supply line during pressure build-up and during circulation took place from above, the gas discharge at holding level and pressure reduction downwards. A sealing ring between the upper limit of the tobacco insert pot and the autoclave lid ensured the direct entry of the gas into the tobacco insert pot.
• Example 2 The procedure was analogous to Example 2, wherein during the pressure reduction, a holding level of 1 min at 50 bar constant adjusted and heated gas from a second, referred to as a donor autoclave was introduced into the treatment vessel.
• the donor had a pressure of 100 bar and an operating temperature of 80 ° C with a content of 4 l before the overflow.

• Example 2 and 3 show, in contrast to Example 1, in which the heating by holding time at preselected holding level or preselected pressure increased working temperature requires that the circulation according to Example 2 via heat exchangers or the gas transfer from the donor according to Example 3 at a constant holding level or constant pressure even at a working temperature of gas-receiving, designated as acceptor Treatment vessel from 40 ° C to an elevated Lead discharge temperature.
