Description

Online tobacco flake omnibearing controlled non-smoke substance removing method

Technical Field

The invention relates to the field of tobacco redrying non-tobacco material removal, in particular to an online tobacco flake omni-directionally controlled non-tobacco material removal method.

Background

Threshing and redrying processing is to provide qualified finished tobacco strips (cigarette raw materials) for the cigarette industry, and non-tobacco substances in the finished tobacco strips are one of important factors influencing the quality of cigarette products and are the key focus of attention of customers.

Tobacco leaves belong to agricultural products, and various non-tobacco substances are inevitably mixed in the planting and picking process, the primary baking processing process, the packaging and storage process and the transportation process, so that the non-tobacco substances are required to be removed from the tobacco leaves as much as possible in the subsequent threshing and redrying processing link, and the quality of cigarette products is finally ensured.

The following is data of the enterprise for detecting the non-smoke substances of the finished tobacco strips, and the specific types and proportions are as follows:

serial number	Name of sundries	Detecting impurity content (amount)%	Cumulative percentage
				1	Hemp thread	43.85	43.85
2	Weeds (Laggera arvensis)	19.95	63.80
				3	Insect cocoon	15.08	78.88
4	Cotton thread	7.19	86.07
				5	Seed of corn	5.10	91.17
6	Feather	2.55	93.72
				7	Palm fiber	1.62	95.34
8	Hair, hair-care product and method for producing the same	1.16	96.50
				9	Plastic material	1.16	97.66
10	Paper sheet	0.93	98.59
				11	Pine needle	0.70	99.29
12	Cigarette scale	0.46	99.75
				13	Others	0.25	100.00

From the distribution of the types of non-smoke substances of the finished product, the detection proportion of the hemp threads is the largest and reaches 43.85 percent, and the detection proportion of the hemp threads, weeds, worm cocoons, cotton threads, feathers, palm threads, seeds, hair, plastics, paper sheets and pine needles accounts for 99.29 percent of the total amount. The key to reducing the content of non-smoke substances in the finished product is to remove the impurities according to the types.

At present, a tobacco leaf threshing and redrying processing production line is generally a production line of 12000 kg/h (the flow of leaves after threshing and separating tobacco stems is about 9000 kg/h), and each main processing flow is as follows: spreading leaves, feeding, primary wetting, winnowing non-tobacco material removal (screening sand), manually selecting on line, secondary wetting, leaf and stem separation line (combination of four times of eleven air minutes), hemp thread removing roller table combination, photoelectric non-tobacco material removal, re-baking leaves and packaging finished leaves.

In the threshing and redrying process, the mainly adopted links of non-tobacco material removal are as follows: manual leaf spreading and feeding, winnowing non-smoke substance removal, manual online selection, hemp thread removing roller table combination and photoelectric non-smoke substance removal. The following analyses were performed for these heterocyclic ring-rejecting operations:

a step of manual leaf laying and feeding: the main task is to lay leaves and feed, the visible label hemp rope is only an additional task, and the impurity removal control capability of the link is not strong because the tobacco leaves are adhered and not dispersed and the non-smoke substances in the tobacco leaves are not fully exposed;

winnowing non-smoke substance removal (sand screening): the link is arranged after the tobacco leaves are moistened for one time, the tobacco leaves are still in a conglomerated state and are not fully dispersed, the water vapor is heavy, and the non-tobacco substances scattered in the tobacco leaves can only be removed in the winnowing process, so that the link is only under the condition of insufficient control, and the control capability of the non-tobacco substances is not strong.

Manual on-line selection: the task of the link is to manually select non-tobacco substances and mottled tobacco, the tobacco leaves in the link depend on manual dispersion and manual selection, the controlled result of the non-tobacco substances is unstable and is greatly influenced by human factors, and the overall control capability is weak.

Removing hemp thread and combining roller ways: the link is that hemp thread removing roller ways are arranged on a gathering belt of the threshing blades, and the hemp threads in the blades are adhered and removed by utilizing adhesive hasps arranged on each rotary roller way. The removing mode has great defects that firstly, the online material flow is large, so that the online material cannot be contacted with all materials, and secondly, the adhered hemp threads cannot be cleaned online, so that the adhered agraffe is quickly adhered with the hemp threads to lose effectiveness; this way it is not possible to achieve a continuous (uninterrupted) rejection function for all the material.

Photoelectric non-smoke substance elimination: the link is arranged after a threshing process (before a redrying process), and the photoelectric non-smoke substance removal is a system for monitoring non-smoke substances in the threshed tobacco flakes in a photographic mode and blowing out the non-smoke substances pneumatically. The electro-optical non-smoke material rejection system is unable to reject smoke flakes due to too large an on-line flow of the lamina (9000 kg/hr) to disperse completely and non-smoke material not detected (not visible) by the camera due to the masking effect of the lamina itself. The photoelectric non-smoke material eliminating system also has limitation.

Through analysis of the threshing and redrying processing flow and a common non-tobacco substance removing mode, two main factors influencing low on-line tobacco leaf non-tobacco substance removing efficiency exist, namely, the on-line processing flow is too large; secondly, the existing removal modes are all chip type and random removal modes, the continuous non-smoke material removal function aiming at all materials cannot be realized, and a large part of materials cannot be in a controlled state. That is, the content of non-smoke substances in the finished tobacco sheet processed by threshing and redrying is still in a state of being out of control.
