Drying device for reconstituted tobacco production by means of dry method of paper-making

Abstract

The invention relates to a drying device for reconstituted tobacco production by means of a dry method of paper-making. The drying device comprises a drying oven body, and a hot air inlet 11 connected with the drying oven body, wherein a first air uniformizing baffle 1, a second air uniformizing baffle 2 and a third air uniformizing baffle 3 are fixedly arranged in the drying oven body in parallel at equal intervals, the three air uniformizing baffles are arranged in the drying oven body and connected with the hot air inlet 11, an adjustable baffle is arranged at the tail end of each air uniformizing baffle, and a forced dehumidification device 7 is arranged on the rear portion of the drying oven body. The drying device has the advantages that blast capacity is uniform and the internal humidity of the drying device can be effectively reduced and is suitable for a reconstituted tobacco production line with the dry method of paper-making adopted.

Description

[0001] The present invention claims the priority of the Chinese invention patent application date of March 7, 2014 and application number CN2014100836704 for a drying device for producing reconstituted tobacco leaves by dry papermaking. technical field [0002] The invention belongs to the technical field of tobacco material production. Specifically relates to a drying device suitable for producing reconstituted tobacco leaves by dry papermaking. Background technique [0003] Reconstituted tobacco leaves are tobacco flakes, also known as recombined tobacco leaves, homogeneous tobacco leaves, mainly composed of tobacco powder fragments, tobacco stems or low-grade tobacco leaves, plus some foreign fibers, adhesives and other additives. Reconstituted tobacco leaves have been widely used in cigarette production as a raw material for tobacco products, and have the advantages of low cost and good filling properties. And can reduce the tar content in the flue gas and other charact...

AI Technical Summary

Problems solved by technology

The existing dry papermaking method produces reconstituted tobacco leaves by entering the hot air from the heat exchanger into the oven to dry the reconstituted tobacco leaves. The temperature and the uniformity of hot air during drying will have an impact on the strength and quality of dry-laid papermaking reconstituted tobacco leaves

[0005] The drying device of the existing dry-laid paper machine cannot meet the needs of manufacturing and producing the reconstituted tobacco leaves of the dry-laid papermaking method. There are two main defects in the drying process: 1. There is no uniform air device in the existing oven. The hot air enters the oven box, and the hot air is naturally distributed, resulting in uneven hot air in various parts. When drying the reconstituted tobacco leaves by dry-process papermaking, it often occurs that some parts cannot be dried, and some parts are over-dried, resulting in the tobacco substance. Drain, and even a problem similar to baking aroma

2. There is no forced dehumidification device between the ovens on the existing dry-laid paper machine production line, and the drying of reconstituted tobacco leaves in the dry-laid papermaking method is done by connecting one set of ovens to the next set of ovens.

If it is not solved, it is difficult to meet the drying process of reconstituted tobacco leaves

[0006] Chinese patent application CN201310393610.8 discloses a fully assembled production line for dry-laid papermaking reconstituted tobacco leaves, but does not mention the special requirements for the drying device in the dry-laid papermaking method for reconstituted tobacco leaves, and does not propose a hot air uniform air solution in the oven , so the package production line described in this patent is difficult to meet the requirements for the production of dry-laid papermaking reconstituted tobacco leaves, and it is difficult to produce qualified dry-laid papermaking reconstituted tobacco leaves
