Problems solved by technology

[0003] However storage of tobacco leaves is a problem
In order to solve the storage problem of tobacco leaves, people use sulfur fumigation. Although the tobacco leaves after fumigation can be stored for a long time, there will be more or less sulfur compounds on the tobacco leaves.
If it is made into shredded tobacco, it is not conducive to people's health

Embodiment 1

[0017] Rinse the tobacco first, and use high-pressure water to remove impurities on the surface, then cut the tobacco into sections, and put the cut tobacco into a closed reactor, the reactor is equipped with steam Injection device, ultrasonic generating device, etc. The reactor is provided with several layers of screens, and the tobacco is respectively placed on several screens. The steam injection device has several injection heads, which are evenly distributed in the reactor. It is convenient for the steam to be evenly distributed on the tobacco.

[0018] First spray the tobacco in the reactor with steam, after spraying for 4 to 5 minutes, continue to spray, and start ultrasonic treatment at the same time, the ultrasonic power is 200 to 300W, and the time is 20 to 30 minutes. Then, the tobacco is tested and small pieces are selected. Tobacco samples, grind the samples, prepare the liquid in a centrifuge tube, put it into a high-speed centrifuge, and put it into an automati...

Abstract

The invention discloses a method of removing sulfur compounds in tobacco. According to the method, firstly, the tobacco is washed with high-pressure water to remove impurities on the surface; secondly, the tobacco is segmented, the segmented tobacco is placed in an airtight reactor, the reactor is provided with a steam jet device, an ultrasonic generation device and the like, steam jet is performed on the tobacco in the reactor firstly, jet is continued after being performed for 4-5 minutes, and meanwhile ultrasonic treatment is performed at the ultrasonic power of 200-300W for 20-30 minutes;thirdly, the tobacco is detected, if the sulfur compounds dot not reach a standard, the ultrasonic power is regulated to 350-400W, jet is continued, and meanwhile microwave treatment is performed for15-20 minutes; and secondary detection is performed, and the tobacco is dried after the standard is reached.

Description

technical field [0001] The invention belongs to the technical field of tobacco treatment, and in particular relates to a method for removing sulfur compounds in tobacco. Background technique [0002] Tobacco leaf is an annual or limited perennial herb, Solanaceae. The mature tobacco leaves are first steamed at high temperature (or they may be first roasted, the taste of the tobacco leaves is different depending on the temperature and time). Then put the tobacco leaves into the machine (mainly sorting and cleaning up the sundries and cutting the tobacco leaves), and the large tobacco leaves gradually become small compressed tobacco leaves. Then cut into shreds. Finally, it enters the packaging, the machine packaging is very uniform (this is also the main feature that distinguishes fake cigarettes), the filter tip and shredded tobacco are packaged together and cut into sections, and the finished cigarette is ready. [0003] However storage of tobacco leaves is a problem. I...
