Problems solved by technology

However, the soft beating and subdividing process does not change the traditional mode of air separation for leaf threshing, and the leaves and stems are repeatedly torn due to the addition of leaf threshing units; and the increase in air separators leads to a decrease in crushing rate and energy consumption Increase

Embodiment 1

[0036] Example 1 (eg figure 1 )

[0037] A threshing and redrying process, comprising a tobacco leaf wetting step and a leaf threshing step for wetting the tobacco leaves, characterized in that the threshed tobacco leaves undergo the following steps:

[0038] A. On the air separation unit, carry out primary winnowing to the tobacco leaves after threshing according to the air separator efficiency 62%, and obtain the winnowing product and the winnowing residue with a stalk-containing rate of 2.3%, and the winnowing product is sent into the air-separating product containing In the stalk leaf sorting device, the product and residue are further separated, the product is sent out through the leaf collection belt, and the residue is returned to leaf threshing;

[0039] B, on the secondary air separation unit, under the condition that the efficiency of the air separator is 62%, the wind selection residue of step A is carried out by wind selection, and the wind separation product and...

Embodiment 2

[0045] Example 2 (eg figure 2 )

[0046] A threshing and redrying process, comprising a tobacco leaf wetting step and a leaf threshing step for wetting the tobacco leaves, characterized in that the threshed tobacco leaves undergo the following steps:

[0047] A. On the air separation unit, under the condition that the efficiency of the air separator is 50%, the tobacco leaves after threshing are carried out to a first-level winnowing, and the winnowing product and the winnowing residue with a stalk rate of 1.8% are obtained. The selected product is directly sent out through the blade collection belt;

[0048] B, on the secondary air separation unit, under the condition that the air separator efficiency is 55%, the air selection residue of step A is carried out by air selection, and the air selection product and air selection residue with a stalk rate of 2% are selected. The air-selected products are directly sent out through the blade collection belt;

[0049] C, on the th...

Embodiment 3

[0054] Example 3 (as image 3 )

[0055] A threshing and redrying process, comprising a tobacco leaf wetting step and a leaf threshing step for wetting the tobacco leaves, characterized in that the threshed tobacco leaves undergo the following steps:

[0056] A. On the air separation unit, under the condition that the efficiency of the air separator is 50%, the tobacco leaves after threshing are carried out to a first-level winnowing, and the winnowing product and the winnowing residue with a stalk rate of 1.8% are obtained. The selected product is directly sent out through the blade collection belt;

[0057] B, on the secondary air separation unit, under the condition that the air separator efficiency is 52%, the air selection residue of step A is carried out by air selection, and the air selection product and air selection residue with a stalk rate of 1.9% are selected. The air-selected products are directly sent out through the blade collection belt;

[0058] C, on the t...

Abstract

The invention provides a tobacco leaf threshing and redrying process. The tobacco leaf threshing and redrying process includes steps of a tobacco leaf wetting step, a wet tobacco leaf threshing step and a multi-stage winnowing step. The tobacco leaf threshing and redrying process is characterized in that in at least one stage of the multi-stage winnowing step, winnowed products with stem ratio lower than 2% are directly discharged, winnowed products with stem ratio higher than 2% are fed into a stem-contained tobacco leaf sorting device and are further sorted to obtain products and residues, the products are discharged, and the residues are fed back to thresh. By improving efficiency of a winnowing device, more large and medium-sized tobacco leaves and stem-contained tobacco leaves can be winnowed to the greatest extent, and by matching with the stem-contained tobacco leaf sorting device, and the stem-contained tobacco leaves can be further removed and fed back to thresh, so that rate of the large and medium-sized tobacco leaves is increased by about 7% on the original basis, and meanwhile, stem containing rate in the tobacco leaves is greatly reduced to lower than 0.5% which is much lower than the nation-regulated standard of 1-2%, and can be accurately effective controlled, tobacco stem and leaf threshing times can be reduced, smashing rate of the tobacco leaves is decreased and cigarette quality is improved.

Description

technical field [0001] The invention relates to a threshing and redrying process, which belongs to the technical field of tobacco leaf threshing and redrying processing. Background technique [0002] Threshing air fractionation is an important link in the process of tobacco leaf threshing and redrying. The quality of threshing air fractionation directly affects important production indicators such as the unit cut tobacco consumption in the final cigarette production, as well as the quality of cigarette smoking taste. In the process of leaf threshing and air separation, the quality control indicators include: the yield of slices, the rate of large and medium slices, the rate of small slices, the rate of fragments, the rate of stems in leaves, the rate of long stems, the rate of short stems, and the percentage of leaves in stems. Among them: the output rate is an important index reflecting the utilization rate of tobacco leaves, and it is also an important indicator to ensure ...
