Abstract

The improved Burley tobacco sheet treating process includes twice additions of liquid material before roasting, and increased Bruley leaf storing step and Bruley leaf moistening step between the twice additions. The liquid material adding amount of the first addition accounts for 50-67 % of total amount and results in Bruley tobacco leaf water content of 23-30 %; and the liquid material adding amount of the second addition accounts for 33-50 % of total amount and results in Bruley leaf water content of 30-35 %. The Bruley tobacco leaf storing step has time controlled in 0.5-3.0 hr, Bruley tobacco leaf moistening step is at 40-60 deg.c, and the second addition step has Burley tobacco sheet temperature increased to 60-100 deg.c. The present invention can make Burley tobacco sheet absorb liquid material homogeneously, increase the compatibility of its chemical components and raise its quality.

Description

(1) Technical field: [0001] The invention relates to a tobacco processing technology, in particular to a processing technology of burley tobacco sheets in the manufacturing process of mixed cigarettes in the tobacco processing industry. (two) background technology: [0002] Blended cigarettes are one of the main types of cigarettes in the world, and the proportion of Burley tobacco leaves in the leaf formula of blended cigarettes is generally more than 30%. Burley tobacco is a porous tobacco leaf with thin leaves, loose tissue, and can absorb a large amount of external feed liquid. In terms of chemical composition, compared with other types of tobacco leaves, Burley tobacco leaves have higher nitrogen content and lower sugar content, so they are more miscellaneous and irritating. They need to be processed separately before being mixed with other types of tobacco leaves into shredded, Rolling process. The processing technology of Burley tobacco sheet generally adopts the me...
