Description

Technical Field

[0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a leaf threshing, redrying and homogenizing processing method. Background Art

[0002] The leaf threshing and redrying process is to mix and roast similar materials from multiple tobacco producing areas, that is, a redrying production formula, which is a finished tobacco strip made from a combination of tobacco leaves from multiple producing areas. It is an important link between tobacco agriculture and tobacco industry. The finished tobacco strips after leaf threshing and redrying should not only reflect the quality and style characteristics, but also have good product consistency and stability. The quality characteristics and uniformity of finished tobacco strips directly affect the quality and stability of downstream finished cigarettes. The nicotine variation coefficient is an important indicator for measuring the homogeneity of finished tobacco strips. At present, the industry conducts online real-time nicotine detection on tobacco leaves by constructing an online nicotine prediction model, and classifies and stacks and processes them. Under flat warehouse conditions, the homogenization control method that uses the nicotine content of tobacco leaves as a parameter for classification and matching has a large number of tobacco leaf samples tested and a certain time lag. At the same time, the classification of semi-finished tobacco leaves in and out of the warehouse is relatively complicated; and the investment and operation costs of the high-bay warehouse homogenization control method are very high. Therefore, it is necessary to adopt an effective homogenization feeding processing method in the initial tobacco assembly stage.

[0003] During the production process, the industry currently builds an online nicotine prediction model to conduct online real-time nicotine detection on tobacco leaves and classify them for stacking and processing. Under flat warehouse conditions, the homogenization control method uses the nicotine content of tobacco leaves as a parameter for classification and matching. The number of tobacco leaf samples tested is large, and there is a certain time lag. At the same time, the classification, storage and outbound operations of semi-finished tobacco leaves are relatively complicated. The investment and operating costs of the homogenization control method in elevated warehouses are very high. Summary of the invention

[0004] The object of the present invention is to provide a leaf threshing, re-roasting and homogenizing processing method to solve the problems existing in the above-mentioned background technology.

[0005] To achieve the above objectives, this application is implemented through the following technical solutions:

[0006] A leaf threshing, re-roasting and homogenizing processing method comprises the following steps:

[0007] S1. Obtain parameter information of the formula feed list, and divide into several groups based on the formula ratio in the established formula and the information of the feed tobacco leaves;

[0008] S2. Calculate the feed amount of each group in a single batch according to the proportion of each group and the number of batches;

[0009] S3. Based on the formula characteristics and the single batch feeding amount, several feeding groups are divided;

[0010] S4. According to the single batch feeding amount, feeding ratio, and total feeding amount of a single group, the feeding amount of each group of tobacco leaves in each feeding round is calculated;

[0011] S5. Allocate the number of feeding personnel based on the feeding amount of each group of tobacco leaves in each feeding round, and distribute them on the leaf laying platform according to the set rules;

[0012] S6. By utilizing the time difference of the mixing belt, the feeding ratio and nicotine homogenization can be achieved when the tobacco leaves reach the climbing belt.

[0013] Furthermore, in step S1, the information of the tobacco leaves includes one or more of the nicotine content of the tobacco leaves, the sugar-alkali ratio of the tobacco leaves, the origin of the tobacco leaves, and the grade of the tobacco leaves.

[0014] Furthermore, in step S2, the feeding amount of each group in a single batch = the proportion of each group ÷ the number of batches fed,

[0015] , where S n Represents the amount of each group in a single batch, unit: Kg, P n Represents the proportion of each group, unit: dan, B represents the total batch size, and n represents the number of groups.

[0016] Furthermore, the number of frames in each group is, , where Q n It represents the number of tobacco frames for each group, unit: pieces; M represents the capacity of one frame of industrial graded tobacco, unit: kg.

[0017] Furthermore, the total number of tobacco leaves packed in frames is, , where Q Hn , Q Mn , Q Ln They respectively represent the number of frames of tobacco leaves classified by characteristics.

[0018] Furthermore, in step S5, the number of people feeding in each group is, , where a n represents the number of people feeding in each group, unit: person, c represents the classification characteristics of the tobacco leaves fed, and A represents the total number of people feeding.

[0019] Furthermore, a warning device is provided on the leaf laying handle table to remind the feeding personnel to feed the materials accurately.

[0020] The beneficial effects of the present invention are:

[0021] This technical solution improves the uniformity and homogenization of feeding: by accurately calculating the feeding amount of each group of tobacco leaves, it solves the problem of unscientific grouping in the traditional redrying feeding process. It divides tobacco leaves into different groups based on the established formula ratio and the nicotine value of tobacco leaves, and further subdivides based on the feeding amount of a single batch, ensuring that the feeding amount of each group of tobacco leaves in each feeding round can meet the preset standard. By utilizing the time difference of the running of the mixing belt, the feeding ratio and nicotine homogenization are achieved when the tobacco leaves reach the climbing belt, which significantly improves the quality stability of the finished redrying tobacco leaves.

[0022] This technical solution reduces the complexity and cost of manual feeding: through refined grouping and calculation, the feeding amount of each group of tobacco leaves, the number of feeding personnel required, and the workload of feeding personnel can be clearly defined, making the feeding process more orderly and efficient. Personnel stand on the mixing belt according to groups to feed, which reduces the complexity and uncertainty of manual operation and improves the controllability and stability of the feeding process. At the same time, since the number of unpacking and tobacco leaf crushing is reduced, production costs are further saved.

[0023] This technical solution improves the quality stability of finished tobacco strips: uniform feeding and homogenization processing ensure that the coefficient of variation of nicotine in the finished tobacco strips is effectively controlled, and contributes to the quality and stability of downstream finished cigarettes, meeting the tobacco industry's high requirements for raw material quality.

[0024] The technical solution has wide applicability: it is not only suitable for the redrying production feeding method using nicotine amount as a grouping method, but can also be extended to the situation where different origins and different grades are used as feeding formulas. This versatility makes the present invention have a wider application prospect and higher practical value. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Figure 1 This is an operation flow chart of the leaf threshing, re-roasting and homogenizing processing method of the present invention.

[0026] Figure 2 It is a schematic diagram of the leaf-laying swing table workstation of the present invention. DETAILED DESCRIPTION

[0027] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, but cannot be construed as limiting the technical solution of the present invention.

[0028] like Figure 1 and Figure 2 As shown, a leaf threshing, redrying and homogenizing processing method comprises the following steps:

[0029] S1. Obtain parameter information of the formula feed sheet, and divide into several groups based on the formula ratio in the established formula and the information of the feed tobacco leaves; each brand of tobacco leaves involves a specific formula, and the parameter information of the formula is determined by the designer. The information of the feed tobacco leaves is provided by the tobacco leaf raw material party or the purchasing department, and is reflected in the warehousing information of the tobacco leaf warehouse, and also includes relevant inspection information of the tobacco leaves by the inspection department. In this embodiment, the information of the feed tobacco leaves is grouped by the nicotine content of the tobacco leaves. In other embodiments of the present application, one or more of the sugar-alkali ratio of the tobacco leaves, the origin of the tobacco leaves, and the grade of the tobacco leaves are also included as grouping methods.

[0030] S2. Calculate the feed amount of each group in a single batch according to the proportion of each group and the number of batches;

[0031] In step S2, the feeding amount of each group in a single batch = the proportion of each group ÷ the number of batches put in,

[0032] , where S n Represents the amount of each group in a single batch, unit: Kg, P n Represents the proportion of each group, unit: dan, B represents the total batch size, and n represents the number of groups.

[0033] Since the capacity of each frame of industrial graded tobacco leaves is M kilograms (usually 400 kg per frame), first divide the specific number of frames in each group.

[0034] The number of frames in each group is, , where Q n It represents the number of tobacco frames for each group, unit: pieces; M represents the capacity of one frame of industrial graded tobacco, unit: kg.

[0035] The total number of tobacco leaves in the packaging is, , where Q Hn , Q Mn , Q Ln They respectively represent the number of frames of tobacco leaves classified by characteristics.

[0036] S3. Based on the formula characteristics and the single batch feeding amount, several feeding groups are divided;

[0037] S4. According to the single batch feeding amount, feeding ratio, and total feeding amount of a single group, the feeding amount of each group of tobacco leaves in each feeding round is calculated;

[0038] S5, based on the amount of tobacco leaves fed to each group in each feeding round, the number of feeding personnel is allocated and distributed on the leaf laying platform according to the set rules; in step S5, the number of feeding personnel in each group is, , where a n represents the number of people feeding in each group, unit: person, c represents the classification characteristics of the tobacco leaves fed, and A represents the total number of people feeding.

[0039] S6. By utilizing the time difference of the mixing belt, the feeding ratio and nicotine homogenization can be achieved when the tobacco leaves reach the climbing belt.

[0040] Personnel are assigned according to the high, medium and low nicotine feed amounts. Personnel stand on the mixing belt according to groups to feed the materials. The three belts are started in sequence according to the feeding situation, and the purpose of uniform mixing is achieved at the climbing belt outlet.

[0041] This technical solution achieves homogenized feeding of tobacco leaves through precise calculation, reasonable grouping, precise allocation of feeding amount, and reasonable allocation of feeding personnel. The innovation of this method lies in its ability to significantly improve the homogeneity and stability of finished tobacco leaves, thereby meeting the quality requirements of downstream finished cigarettes.

[0042] The parameter calculation formula used in this technical solution is derived from actual production experience and data optimization, and is highly accurate and practical. These formulas are not only applicable to the case where nicotine value is used as the basis for grouping, but also to the case where the proportion of tobacco leaves in the tobacco station is used as the basis for grouping, and are highly versatile and flexible.

[0043] This technical solution can also add a code scanning device in the feeding process and add a small storage device inside to record the data of each scan for subsequent analysis and tracking. Add a metering device to the feeding table to remind the user whether the feeding amount is accurate and reduce uneven feeding caused by human factors. Add a sound or light warning device to the feeding table to remind the user whether the feeding is accurate and reduce erroneous operations.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
