Problems solved by technology

Its advantage is high filling capacity, reaching 6.5cm3 / g~7.3 cm3 / g, which can effectively remove miscellaneous gases in shredded tobacco, improve the product quality of cigarettes, and reduce the amount of tar in cigarette smoke; its disadvantage is that during the production process, the production of shredded tobacco Larger shreds, serious loss of some chemical components of shredded tobacco, more aroma loss, heavy burnt smell, dry smoke, 50% to 60% lower change rate of shredded shreds, high production cost, and carbonization of shredded tobacco during the production process, serious Sometimes even fire and smoke, and have CO 2 pollution

Embodiment 1

[0024] A cutting tobacco expansion process using water as the medium, the steps are as follows:

[0025] (1) Rinsing of tobacco slices: continuous rinsing of the loose recured tobacco slices into the washing tank after quantitative feeding, the water flow rate is 0.1m / s, the rinsing water temperature is 25°C, and the moisture content of the tobacco slices after rinsing is 45% (rinsing time 20s );

[0026] (2) Differential speed thinning: After the washed smoked sheets are filtered through the mesh belt, the material is thinned by differential feeding. The speed of the low-speed belt is 2m / s, and the speed of the high-speed belt is 4m / s. A leveling roller is used above the high-speed belt Dilute the material to a material thickness of 10mm;

[0027] (3) Infrared drying and feeding: the leaves are dried by infrared drying until the moisture content is 16% before feeding. The infrared wavelength is 6 μm, the infrared power is 18kw, the drying temperature is 70°C, and the drying ...

Abstract

The invention provides a tobacco shred expanding process adopting water as a medium. The process comprises the following steps: after loosening, enabling redried tobacco strips to be subjected to continuous rinsing for 10-30 s in the medium, namely, water, so as to obtain tobacco strips with the water content being 40-50%, carrying out redrying and casing in a mesh belt, carrying out strip bakingby adopting infrared rays to enable the water content to achieve 18-20%, carrying out shredding, carrying out super resurgence so as to realize temperature increase and humidity increase on the tobacco shreds and improve the water content of the tobacco shreds to 30-40%, carrying out instantaneous heating by adopting vacuum microwave in an expanding device, so as to sufficiently gasify water in tobacco shred cells, enable water vapor to rush out of the cells and further to sufficiently expand the tobacco shreds and obtain tobacco shreds with the water content being 12-13% and the filling valuebeing 5.5 cm<3> / g-7.0 cm<3> / g, carrying out flexible winnowing, and storing the expanded tobacco shreds for later use.

Description

technical field [0001] The invention belongs to the field of tobacco, and in particular relates to a shredded tobacco expansion process using water as a medium. Background technique [0002] During the current cigarette production process, CO 2 Cut tobacco expansion technology is the most mature and popular. Its main steps are: the tobacco leaves are subjected to vacuum re-moisture, loose re-moisture, mixed pre-storage and shredded tobacco leaves to obtain shredded leaves with a water content of 22% to 24%. 2 Dipping for a certain period of time for 60s to form dry ice shreds. After loosening, they are then heated instantaneously by hot air at a high speed of 27m / s to 31m / s at a high temperature of 320°C to 350°C. Fully expand to make leaf shreds with a moisture content of 6% to 8%, and after regaining moisture, meet the requirement of moisture content of 12.7% to 13.8%, and store for use. Its advantage is high filling capacity, reaching 6.5cm3 / g~7.3 cm3 / g, which can effec...
