A kind of online drying method of heating cigarette cut tobacco

Abstract

The object of the present invention is to provide a novel online drying method for heated cigarette cut tobacco, which comprises the following two steps: step 1) increasing the moisture content of natural tobacco leaves to 18.5-20.5% through the leaf making section, cutting into shreds, and shredding the width of the shredded tobacco. Controlling to 0.9 to 1.1 mm; Step 2) Drying the cut tobacco with high-temperature air flow to reduce the moisture content of the cut tobacco to 9.5-10.5%; Step 3) Carrying out a warming and moistening treatment for the cut tobacco, increasing the temperature of the cut tobacco to 86°C±3, and controlling The content of the humectant in the cut tobacco is 2-6%; step 4) the cut tobacco is subjected to drum drying treatment to reduce the moisture content to below 3%.

Description

technical field [0001] The invention belongs to the field of novel tobacco, and in particular relates to an on-line drying technology for shredded tobacco of heated cigarettes. Background technique [0002] Compared with traditional cigarettes, the basic condition for the new type of heated cigarettes to smoke is that the cut tobacco needs to be preheated to about 300°C. If the moisture in the cut tobacco is not sufficiently treated, water vapor will be generated during smoking, resulting in high smoke temperature. According to research, if natural tobacco leaves are to be used in heated cigarettes, it is necessary to reduce the moisture content of cut tobacco to less than 3%, so as to avoid excessive smoke temperature caused by water vapor during smoking. SUMMARY OF THE INVENTION [0003] In view of the technical problem that the cut tobacco moisture is too low in the production process of the cut tobacco, resulting in a sharp increase in the amount of shredded shreds and...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the technical problem that the cut tobacco moisture is too low in the production process of cut tobacco, the amount of shredded shreds increases sharply to cause waste of shredded tobacco. The present invention adopts the combined drying production mode of "high-temperature airflow drying + warming and moistening + low-temperature drum drying" to ensure the moisture content of cut tobacco. Under the condition of less than 3%, increase the whole filament rate to more than 80%; at present, there is no similar production technology and production line for new heating cigarettes in the industry
