Problems solved by technology

The disadvantage is that the overall efficiency is low, the production cost is high, the large-scale production investment is high, and the extraction process cannot be automatically controlled, etc., resulting in unstable quality of reconstituted tobacco leaves
Some newly developed extraction processes present technical difficulties when scaled up
At the same time, the research on the extraction of tobacco stems in the tobacco industry is not yet mature enough to meet the technical and technical requirements of large-scale industrial production of paper-making reconstituted tobacco leaves, such as production capacity, clean production capacity, physical and chemical regulation, quality stability, and formula applicability. requirements

Embodiment 1

[0035] The continuous countercurrent extraction process of raw material tobacco stems of reconstituted tobacco leaves, such as figure 1 shown, including the following:

[0036] Step 1: Pretreatment of Tobacco Stems

[0037] The measured tobacco stem raw materials are sent to the drum type stem washing machine for stem washing; after washing the stems, they are sent to the tobacco stem dampening machine through the water filter screw conveyor, and the tobacco stems are swelled at 70-80°C to complete Pretreatment of tobacco stems; after the pretreatment is completed, the moisture content of tobacco stems increases by 2% to 5%;

[0038] Step 2 Ⅱ: Coarse Fiber Decomposition of Tobacco Stems

[0039] Put the pretreated tobacco stem raw material into the double-helix thread rolling machine, and break the cell wall of the tobacco stem through rubbing to achieve the purpose of accelerating extraction;

[0040] Step 3 III: Extraction and solid-liquid separation

[0041] Send the to...

Abstract

The invention discloses a continuous countercurrent extraction process and extraction system for reconstituted tobacco raw material stems, and aims to provide a continuous countercurrent extraction process and extraction system for reconstituted tobacco raw material stems, which arelow in cost and high in extraction ratio, save energy, are environmentally friendly and facilitate forming with pulp.The extraction process includes the first step of pretreatment of tobacco stems; the second step of rough solution of tobacco stems; the third step of extraction and solid-liquid separation; and thefourth step of first-stage separation liquid purification. The continuous countercurrent extraction process and extraction system are applicable to the use of various reconstituted tobacco leaves.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf processing, in particular to a continuous countercurrent extraction process and an extraction system for tobacco stems, which are raw materials of reconstituted tobacco leaves. Background technique [0002] The tobacco stem extraction process is one of the key processes in the production process of paper-making reconstituted tobacco leaves, and it plays a vital role in improving the technical level and product quality of paper-making reconstituted tobacco leaves. The development of the tobacco industry has entered a new historical stage, especially the implementation of the level of brand development and technological innovation, which puts forward higher requirements for improving the brand value of cigarettes, reducing harm and reducing tar, and product quality and safety. As one of the important means to solve these problems, papermaking reconstituted tobacco has been given a higher respon...
