Tobacco stem-leaf separating and re-curing process

A technology of threshing, redrying and stalking, which is applied in the directions of tobacco, tobacco preparation, tobacco treatment, etc., can solve the problem that the physical properties of tobacco stems and leaves cannot be well taken into account, the horizontal threshing unit has a large load, and the utilization of tobacco stems is unfavorable. and other problems, to achieve the effect of small footprint, increase production capacity, and reduce the number of threshing and wind grading.

Problems solved by technology

The above two threshing and redrying processes do not separate the stems from the leaves. When processing, they often only focus on the index requirements of the leaves, and cannot take into account the physical characteristics of both tobacco stems and leaves. The leaves are separated from the first stage of the horizontal threshing unit until the end, resulting in a large load on the horizontal threshing unit and a decrease in the long stem rate, which is not conducive to the utilization of tobacco stems

Embodiment Construction

[0024] As shown in the figure, the technological process of the present invention is as follows:

[0025] ①Put the tobacco leaves one by one on the leaf cutting table, and cut and separate the stems mainly composed of tobacco stems from the leaves mainly composed of leaves;

[0026] ②The stem material will be processed according to the following process route:

[0027] a) Send the stalks into the constant flow control system composed of feeder and electronic scale to control the stable material flow;

[0028] b) Pack the stem material into a continuous vacuum dampening system for vacuum dampening treatment, and then send it to a drum type leaf conditioner for warming and humidifying treatment. The warming and humidifying treatment can be carried out several times according to the condition of the tobacco stems, and then carry out Storage, so that the tobacco stems can fully absorb water and improve the toughness and processing resistance of the material;

[0029] c) Use a vi...

Abstract

The tobacco stem-leaf separating, threshing and re-curing process includes the separation between tobacco stem and tobacco leaf and the following separated tobacco stem and tobacco leaf treating steps: 1. feeding to constant flow rate controlling system; 2. tobacco stem material temperature and humidity increasing treatment and storing; and tobacco leaf material vacuum remoistening and / or temperature and humidity increasing treatment; 3. sieving out silt; 4. wind separating out other impurity; 5. feeding to constant flow rate controlling system; 6. the last temperature and humidity increasing treatment; 7. eliminating metal impurity; and 8. separating tobacco stem from tobacco leaf in a vertical threshing machine and a horizontal threshing machine, and final separated re-curing and packing of tobacco stem and tobacco leaf. The present invention treats tobacco stem and tobacco leaf separately to reach ideal treating effects.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf threshing and redrying. Background technique [0002] Tobacco farmers have to classify and tie the tobacco leaves after the initial roasting of the tobacco leaves. The base part of the tobacco stem with a high content of tobacco stems is called the stem, and the remaining part of the tobacco stem after removing the stem is mainly the leaves. It is the leaf. [0003] At present, the threshing and redrying process can be divided into two types: the tip-cut leaf threshing and redrying process and the whole leaf threshing and redrying process. The tip-cutting and re-baking process is to manually place the tobacco leaves on the tip-cutting table one by one after the pre-moisture treatment of the tobacco leaves, and then cut them into two parts: the tip and the base. After treatment, the leaves and stalks are separated by the leaf-threshing unit. After the leaf tip part passes the leaf tip treat...
