Tobacco expanding method

Abstract

The invention discloses a tobacco expanding device which comprises a main device body. A first cavity is formed inside the main device body, a rotating roller is in rotating fit connection with the interior of the first cavity, a mixing groove with an upward opening is formed inside the top end face of the rotating roller, a conical gear ring is fixedly arranged on the top end face of the rotatingroller, a second cavity is formed inside the portion, at the lower side of the first cavity, of the main device body, a sliding cavity is formed inside the portion, at the right side of the first cavity, of the main device body, a third cavity is formed in the portion, at the right side of the second cavity, of the main device body, the third cavity is formed in the lower side of the sliding cavity, a conveying cylinder extending left and right is fixedly arranged inside the left side wall of the second cavity, the tail end of the left side of the conveying cylinder stretches out of the leftside end face of the main device body, and the tail end of the right side of the conveying cylinder stretches into the second cavity and is fixedly and cooperatively connected with the end wall of theright side of the second cavity.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a method for expanding tobacco. Background technique [0002] Tobacco expansion is an important measure for the cigarette industry to improve tobacco filling and reduce the tar content of cigarettes. Tobacco expansion technology is used to restore the loose bulk density of tobacco or restore the volume lost during tobacco leaf processing and storage, which is helpful for improving the safety of cigarettes. Significance; the tobacco expansion process needs to go through the mixing of the expansion catalyst and the heating step. The heating step usually makes the tobacco contact with the heat medium such as hot air and / or steam. The heating step causes the expansion agent to be removed from the tobacco, but the traditional tobacco expansion equipment structure Complicated, expensive, high maintenance cost, in addition, small tobacco expansion equipment has poor mixing ef...
