Device and method for removing light and thin pieces in cut stems by using flow guide plate

Abstract

The invention discloses a device for removing light and thin pieces in cut stems by using a flow guide plate. The device comprises a vertically-arranged separation cylinder (T), the cut stem flow guide plate (1) and a cut stem distribution plate (2), wherein the cut stem flow guide plate (1) and the cut stem distribution plate (2) are arranged in the separation cylinder (T). The invention furtherdiscloses a method for removing the light and thin pieces in the cut stems by using the device. By means of the device, the finished cut stems can be fully separated from the light and thin pieces. The device is designed for the first time, occupies a small area and is beneficial to industrial production.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a device and method for removing light flakes from shredded stems by using a deflector. Background technique [0002] Cut stems have always been positioned as an important filler in the tobacco formula structure, and various companies have increased the proportion and value of cut stems by processing cut stems with high filling and high filamentous proportions, and continued to reduce the cost of tobacco formula and processing. At the same time, it also regulates the physical quality such as the weight of cigarettes and the smoke indicators such as tar. [0003] In the actual production process, the quality of incoming tobacco stems is affected by the processing technology level and quality control level of the threshing and redrying enterprises, and the quality of tobacco stems input into cigarette shreds fluctuates greatly, manifested as stem heads or ste...

Problems solved by technology

[0003] In the actual production process, the quality of incoming tobacco stems is affected by the processing technology level and quality control level of the threshing and redrying enterprises, and the quality of tobacco stems input into cigarette shreds fluctuates greatly, manifested as stem heads or stem turns, short The content of unqualified tobacco stems such as stalks and thin stems is relatively high, and due to the restrictions of the industrial and commercial system of the cigarette industry, cigarette manufacturers cannot control the quality of incoming tobacco stems (except for enterprises with industrial threshing and redrying factories)

In this context, the problem of incoming tobacco stems has not been effectively improved

Under the current technical level, this part of tobacco stems enters the cigarette manufacturing process, and unqualified tobacco stems cannot be fundamentally eliminated, resulting in light and thin slices in the processed finished cut stems (often called "fly flakes" in manufacturers, see figure 1 The photo on the right) has a large content, showing defects such as many flakes, white color, low density, and easy to break

At present, most cigarette manufacturers improve the production of light flakes by developing technologies such as on-line multi-layer vibration screening to remove unqualified cut stems, optimizing the stem pressing and cutting process, and reducing the expansion and drying strength of cut stems, but there is no significant reduction in light flakes.
