Die Temperaturen, die bei der Heißlufttrocknung zur Anwendung ·gelangen, liegen bei der Blattvergilbung .im Bereich von 3.5-40° C, bei der Blattrocknung um 500 C und während der letzten Phase, der Rippentrocknung, bei maximal 75-800 C, wobei die Gesamtzeit, die für die Trocknungsvorgänge benötigt wird, 2 bis ; Tage beträgt. Beim Redryverfahren, das sich nach einer gewissen ZwischenZeit der Heißlufttrocknung anschließt, werden die nochmals nachgetrockneten Tabake Temperaturen von So bis :tooO C ausgesetzt, wieder befeuchtet und abgekühlt und verlassen die Maschine mit einer Temp~ratur von ca. 400 C und einem Wassergehalt von :16-:18%. Die Zeitdauer für die Redry. behandlung hängt von der Länge der Maschine und der Transportgeschwindigkeit ab. Nach der Redrybehandlung werden die Tabake verballt oder in Holzfässern verpackt und verbleiben nach ihrem Umschlag in klimaüberwachten Räumen bis zur Verarbeitung. Diese Reifezeit, auch Agin genannt, dauert mehrere Monate.","PeriodicalId":35431,"journal":{"name":"Beitrage zur Tabakforschung International/ Contributions to Tobacco Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1964-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78406092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the basis of equal weights of tobacco consumed, cigarettes gave the highest yields of both nicotine and particulate materials, with lesser amounts, in decreasing order, obtained from an American-type pipe, cigars, and an oriental water pipe. The highest value from 100 g tobacco for benzo[a]pyrene, 27.0 µg, and phenol, 68.7 mg, was found in the smoke of a pipe filled with standard pipe tobacco. A pipe filled with cigarette tobacco yielded benzo[a]pyrene, 10.5 µg, phenol, 21.2 mg; cigarette smoke, benzo[a]pyrene, 7.8 µg, phenol, 25.4 mg; cigar smoke, benzo[a]pyrene, 4.0 and 5.1 µg, phenol, 7.4 and 10.7 mg, with the lowest values for the smoke from an oriental water pipe, benzo[a]pyrene 1.7 µg, phenol, 1.8 mg. The water-filled oriental pipe retained about 90 percent of the phenol of the original smoke. Particulate matter, nicotine, and benzo[a]pyrene were retained to a lesser degree by the water (about 50 %). Increased puff frequency resulted in higher yields of all 4 groups of compounds in the mainstream smoke. Values at 2 puffs per minute frequency ranged from 50 to 120% higher than those at 1 puff per minute when the other smoking factors were held constant. Since biological tests and comparisons of the carcinogenicity of the condensates of cigarettes, cigars, and pipes have previously been carried out on equal weights of condensate, the analytical results of this study were compared in the same manner. One g of the smoke condensates from 85 mm plain cigarettes, 2 types of cigars, and a standard pipe contain 1.25, 3.6, 3.9 and 6.0 µg benzo[a]pyrene, respectively.
