A high-pressure steamed stalk processing technology

Abstract

A technique of processing cut stem by high pressure stem steaming comprises the steps of screening stems, washing stems, expanding the tobacco stems, compressing the stems, cutting the stems, feedingthe cut stem, drying the cut stem, and enhancing aroma of the cut stem. Stem ends in the stems are removed through two-stage stem screening; the stem ends in the stems are effectively removed, stem purity is improved, removal rate of available stems is decreased, and utilization rate of tobacco stems and quality of cut stem are improved; according to stem expanding, the tobacco stems are steamed under the steam pressure of 1.4-1.8 mpa and are expanded under the pressure of 0.4-0.6 mpa, traditional multiple steps of cut stem are replaced by one step, moisture permeability of stems is increasedto 98% and above, and the requirement of the cut stem processing process for moisture permeability of stems is met; the traditional processing flow of cut stem is greatly simplified, the requirement of cut stem layout for spatial area is lowered, the line processing flow of cut stem is shortened, energy consumption of the processing of cut stem is reduced, the production process time of cut stem is shortened, and production efficiency of cut stem is greatly improved.

Description

technical field [0001] The invention relates to a processing method for tobacco products, in particular to a high-pressure steamed shredded stalk processing technology. Background technique [0002] In the traditional shredded stem processing technology, tobacco stems need to be sieved, but mainly thin stems and broken stems are screened out, because thin stems and broken stems are not suitable for being cut during the process of cutting stems due to their small size, and they are easy to form Stem sticks exist in the shredded stems. Even if they are cut, most of them become stem ends, which are screened out in the subsequent process to form waste and cannot be effectively used; at the same time, tobacco stems themselves contain a large amount of pectin. Under the conventional washing and steaming process conditions, moisture is difficult to penetrate, so there is a stem storage process in the traditional shredded stem processing technology, and the storage time is generally...

Problems solved by technology

[0002] In the traditional shredded stem processing technology, tobacco stems need to be sieved, but mainly thin stems and broken stems are screened out, because thin stems and broken stems are not suitable for being cut during the process of cutting stems due to their small size, and they are easy to form Stem sticks exist in the shredded stems. Even if they are cut, most of them become stem ends, which are screened out in the subsequent process to form waste and cannot be effectively used; at the same time, tobacco stems themselves contain a large amount of pectin. Under the conventional washing and steaming process conditions, moisture is difficult to penetrate, so there is a stem storage process in the traditional shredded stem processing technology, and the storage time is generally about 4-24 hours, so that the moisture in the tobacco stems is slow during storage. Penetrating into the interior of the tobacco stems, in order to ensure the full penetration of water, it is even necessary to steam the stems and store the stems multiple times. The process of cut stems is complicated and repeated, and the processing time is long.
