Tobacco stem polishing machine

Abstract

The present invention discloses a tobacco stem polishing machine comprising a machine rack, on which are erected a material propeller and a polishing chamber, wherein the material propeller is positioned at the feed end of the polishing chamber, the material propeller and the polishing chamber are provided with mutually communicated channels, the upper end of the material propeller is provided with a hopper, a screw type propulsion shaft is arranged in the material propeller in a rotation manner, the polishing chamber is composed of a cavity enclosed by an upper cover plate and a lower dust sieve tray, the cover plate is provided with a plurality of ribs and air inlets, a sealing chamber is arranged under the dust sieve tray, out of the sealing chamber is connected a dedusting fan, a polishing roll is arranged in the polishing chamber in a rotation manner, the polishing roll and the screw type propulsion shaft are connected and synchronously driven by a driving control part, and a discharge tank is erected at the discharge end of the polishing chamber. In the process of polishing, the tobacco stem polishing machine can adjust flow rate according to condition of production, realize control of polishing quality of tobacco stems, and carry out instant treatment of dust produced in polishing process.

Description

technical field [0001] The invention mainly relates to a device for polishing the surface of tobacco stems, in particular to a tobacco stem polishing machine, which rubs and polishes the surface of roasted tobacco stems to remove surface attachments such as residual tobacco leaves and burrs on the tobacco stems. Background technique [0002] With the demand and development of the tobacco industry, reducing the tar content of cigarettes has become the goal of cigarette companies. Tobacco stems that were originally burned as waste can be processed into cigarette materials (i.e., shredded stems) after swelling and added to shredded tobacco, which has become an important means of reducing the tar content in cigarettes, and it accounts for an increasing proportion of cigarettes. The greater the value, the importance of tobacco stems as cigarette raw materials is generally recognized by cigarette companies. However, in order to process tobacco stems into shredded stems and add th...

Problems solved by technology

[0005] These tobacco leaves attached to the tobacco stems will fall off a part during the curing, conveying, screening and packaging of the tobacco stems, but in the end there are still about 0.2% of the tobacco leaves and burrs attached to the tobacco stems and cannot fall off. Some of the accompanying tobacco leaves affect the quality of the product during the process of puffing the tobacco stems

[0006] As cigarette companies use more and more tobacco stems, tobacco stems are becoming more and more important as a raw material for cigarettes. Therefore, the requirements for the surface quality of finished tobacco stems are also getting higher and higher. The treatment is mainly to polish it along with the wind conveying process, but this treatment method is passive and cannot be used for quality control; the surface processing equipment and surface quality control measures specially for tobacco stems are still Blank

[0007] In the tobacco leaf processing workshop, the tobacco stem processing section is the hardest hit area for dust generation in the workshop. This is because the tobacco flakes and burrs that fall off from the tobacco stems are ground into a large number of fine powders during the process of screening, conveying and packaging.
