A device and method for loosening cigarette packs using ultrasonic humidification

Abstract

The invention discloses a device and method for loosening cigarette packs by ultrasonic humidification, and belongs to the technical field of tobacco processing. It includes an outer cavity and a cigarette pack receiving device arranged in the outer cavity, an ultrasonic steam generator, and a humidification cavity, and the ultrasonic steam generator is used to generate liquid water mist; the humidification cavity is covered by the cigarette pack Above the pick-up device, two groups of nozzles are arranged in the humidification cavity, and the two groups of nozzles are respectively connected with the ultrasonic steam generator; the injection direction of one group of nozzles is the same as that of the cigarette pack, and the other group of nozzles The injection direction of the tube has an included angle with the layer of the cigarette pack. One group of nozzles repeatedly sprays steam on the cigarette pack along the layer direction, and the steam penetrates into the cigarette pack along the layer gap, and the other group of nozzles sprays to separate the layers of the cigarette pack after moisture absorption and heat up, and the separation between the smoke packs Finally, the steam enters the inside of the cigarette pack more easily, ensuring that the inner and outer leaves absorb moisture and heat up more evenly, so as to achieve the effect of loose cigarette packs.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, and more specifically relates to a device and method for loosening cigarette packs using ultrasonic humidification. Background technique [0002] At present, the raw material of the tobacco shredded production line is cigarette bales with dimensions of 1080*640*670 (length*width*height). Only 12%. When the cigarette bales enter the production line, the compacted leaves should be loosened and the leaves should be dampened to about 17%. This process is called the loosening and dampening process. There are three main modes in the process of loosening and regaining moisture of cigarette packs, one is slicing + loosening and regaining moisture; the other is vacuum regaining moisture + loosening and regaining moisture; the third is microwave heating loosening + loosening and regaining moisture. The existing methods for loosening and regaining moisture in cigarette packs still have problems...

AI Technical Summary

Problems solved by technology

However, due to the different grades of tobacco leaves, the cohesive force will also vary. Tobacco leaves with high cohesive power are loosened by microwave heating, and the effect is not very good.

In addition, due to the low moisture content of the raw material cigarette packs, especially in winter, it is difficult to guarantee the temperature rise of the cigarette packs

There is also the safety issue of microwave leakage

[0008] In addition, such as the Chinese invention patent "Using warm and humid gas to realize the method and equipment for loosening cigarette packs" (application number: 200910027132.2, application date: May 22, 2009), this patent discloses a Under the premise of obtaining a higher loosening rate, effectively maintaining the aroma of tobacco sheets, and lower process costs, the method and equipment for loosening cigarette packs uses warm and humid airflow to peel and loosen, but the temperature of the airflow is still high, which may cause the loss of tobacco flavor. In addition, because the jet airflow adopted is horizontal jet, it will cause looseness and unevenness inside and uneven moisture absorption inside and outside.

This patent uses gas injection. If saturated steam is used, due to the high temperature of the steam, it will be directly sprayed on the tobacco leaves, which will cause damage to the quality of the tobacco leaves itself. If saturated humid air with a lower temperature is used, the water content is too small. Insufficient for smoke sheets to absorb moisture and loosen
