[0018] The preferred embodiments of the present invention are further described below:

[0019] A leaf threshing and re-roasting full-formula pre-feeding processing technology comprises the following steps: manual leaf selection, framing, large frame inspection, whole frame weight determination, classified warehousing, digital warehouse storage, homogenized formula, and one-time assembly and delivery. After the assembly and delivery are completed, the process also comprises the following steps: material preparation before cutting, feeding before cutting, whole frame cutting, cabinet mixing, online inspection, framing after inspection, classified warehousing, secondary assembly and delivery, vacuum rehumidification, material preparation, accurate feeding, and feeding completion.

[0020] The homogenization formula includes a production plan sheet and a process formula sheet.

[0021] The material preparation before cutting is specifically as follows: the tobacco leaves in the warehouse that have been tested and classified on the whole frame chemical composition surface are divided into material preparation lanes for feeding and assembly according to the industrial formula ratio and the chemical composition classification, so as to complete the buffer preparation.

[0022] The whole frame cutting is specifically: the tobacco frame in the buffer area is transported to the cutting equipment for cutting, and the tobacco leaves after cutting enter the silo of the precision feeder according to the grade.

[0023] The feeding before cutting is specifically: cumulatively weighing the cut tobacco leaves to ensure the accuracy of the feeding amount. Under the premise of ensuring the original formula grade ratio, the feeding machine automatically adjusts the feeding flow through precise climbing to achieve precise feeding of the entire line.

[0024] The cabinet mixing is specifically as follows: the precisely fed tobacco leaves are mixed on the aggregation line, and are placed in a large tobacco leaf mixing cabinet in a flat-laying mode for sufficient mixing and temporary storage to ensure the uniformity and adequacy of the tobacco leaf mixing.

[0025] The on-line detection specifically includes: performing near-infrared chemical composition flow detection on the tobacco leaves in the mixing cabinet.

[0026] The post-inspection framing and classified storage specifically includes: calibrating the framed tobacco leaves according to the near-infrared detection results, and storing them in the warehouse according to the classification of chemical inspection data.

[0027] The secondary assembly and delivery is specifically as follows: according to the classified storage situation, the materials are assembled by interval matching, and the frames are turned over in sequence for precise material feeding.

[0028] The process of this application can meet the needs of industrial enterprises for the number of design levels and overall scale of leaf-threshing modules, continuously improve the process realization capabilities of whole material selection and preparation, precise feeding, multi-link impurity removal, and multi-level uniform mixing, and have the ability to use control factors such as color and spectrum to achieve multi-dimensional internal component uniformity, large modules, and multi-level modules. The ability to precisely control the feeding of modules ensures the stable realization of complex module homogenization processing. This application uses a new pre-feeding process to pre-mix the processing raw materials, and feeds them precisely in strict accordance with the industrial formula. At the same time, the mixed tobacco leaves are subjected to secondary chemical composition testing and classified for storage, meeting the purpose of precise control of chemical composition indicators or using a second indicator for control.

[0029] This application designs a leaf threshing and re-roasting pre-feeding process to achieve a "two-level chemical inspection and matching" formula preparation mode:

[0030] The first level of chemical testing is matched, using the near infrared large frame test data after the first selection ( Figure 1The "whole frame inspection" in the system is introduced before the tobacco leaves regain moisture. The fully automatic frame cutting and automated precise feeding technology are introduced, and the online belt-type near-infrared chemical detection equipment is used to match the chemical data of the first large frame inspection and the cutting of the selected tobacco leaves before they are shipped out. Then, the selected tobacco leaves are fed with precise formulas through 12 sets of automated precise feeding equipment, and the second online inspection ( Figure 1 "Online detection (near infrared online detection)" in the system can realize the second-level mixing and packaging and formula preparation and storage, thus improving the representativeness of the detection and the accuracy of the ratio;

[0031] The second-level chemical inspection team uses the second online inspection data to introduce four automatic frame-turning precision feeding equipment in the pre-treatment leaf laying and feeding link to replace the original manual leaf laying table. The cut tobacco leaves are fed according to the batch homogenization processing and proportioning strategy formed by the second online inspection data, and enter the pre-treatment mixing cabinet through the automatic frame-turning feeding equipment, further improving the accuracy of the tobacco leaf proportioning.

[0032] In a specific embodiment, two-level chemical inspection can realize multiple variable control factors, and the two combinations are respectively made according to the ratio combination of the two chemical inspection binding factors. In addition to the physical formula factors, the two combinations are two independent chemical factor combinations. It can realize the application combination of control factors such as nicotine + sugar alkali ratio, nicotine + color, nicotine + spectrum, sugar alkali ratio + nicotine, color + nicotine, spectrum + nicotine, sugar alkali ratio + color, sugar alkali ratio + spectrum, etc. At the same time, the control factors of each level of chemical inspection can also be set with multi-indicator control weight ratio (for example: nicotine accounts for 70%, total sugar accounts for 20%, and total nitrogen accounts for 10%), which can finally achieve multi-dimensional internal component uniformity and precise control of large module and multi-level module feeding.

[0033] The present application is further described below in conjunction with specific embodiments:

[0034] Example 1

[0035] Using the first post-selection large frame inspection data, ny frames (y is set according to the secondary formula library capacity) (400kg or 450kg per frame) of tobacco leaves are grouped and fed according to n grade formulas. Using the second online inspection data, 36 frames (400kg per frame) of tobacco leaves are grouped and fed.

[0036] When n is less than or equal to 12

[0037] Step 1: Adopt the existing homogenization system solution, use the large frame inspection data after the first selection, form chemical inspection and physical formula units according to the grade formula, and send them out to the pre-feeding preparation area.

[0038] Step 2: Using 12 sets of automated precision feeders, n grades are evenly mixed according to chemical inspection and physical formula, and re-framed (400kg per frame) through the second online inspection.

[0039] Step 3: Using the second online detection data, the graded blended formula tobacco leaves are classified and divided into different lanes according to the online detection data and then put into the formula library for material preparation.

[0040] Step 4: Prepare materials in the recipe library. Using the second online test data, 36 frames (400kg per frame) of tobacco leaves are grouped and fed for the second time. After rehumidification, the materials are fed through 4 automatic and precise feeding machines for feeding;

[0041] Step 5: After the feeding is completed, the materials enter the pre-treatment mixing cabinet for storage and a cabinet switching signal is given. The two groups of mixing cabinets work alternately to meet the production efficiency requirements.

[0042] When n is greater than or equal to 12

[0043] Using the large frame inspection data after the first selection, ny frames (y is set according to the capacity of the secondary formula library) (400kg or 450kg per frame) of tobacco leaves are grouped multiple times according to the proportion of n grade formulas to form x small bundled preparation groups. Using the second online inspection data, according to 36 frames (400kg per frame) of tobacco leaves, according to the proportion of small bundled preparation groups, combined with online inspection data, they are extracted separately to form a feeding list for group feeding.

[0044] Step 1: Adopt the existing homogenization system solution, use the large frame inspection data after the first selection, and form ny frames (400kg or 450kg per frame) as a group of chemical inspection and physical formula units according to n grade formulas, and send them out to the pre-feeding preparation area.

[0045] Step 2: Use 12 sets of automated precision feeding machines to accurately feed the X small bundled preparation groups, and re-frame them (400kg per frame) through the second online inspection, and merge them into X merged levels. (Note: The maximum design value of X is equal to 36 subsequent feeding frames, and the maximum level that can be processed at the same time is 12*36. At present, the maximum number of formula levels of redrying enterprises is generally within 60, and x is generally less than or equal to 5)

[0046] Step 3: Using the second online detection data, mix and frame the n grades into x combined grades, classify them according to the second online detection data, divide them into lanes and enter them into the formula library for material preparation again.

[0047] Step 4: Prepare materials in the formula library. Using the second online test data, according to x combined grade chemical inspections and physical formula ratios, perform secondary batching and feeding according to 36 frames (400kg per frame) of tobacco leaves. After rehumidification, use 4 frame-turning automatic precision feeding machines of the secondary batching to turn the frame and feed.

[0048] Step 5: After the feeding is completed, the materials enter the pre-treatment mixing cabinet for storage and a cabinet switching signal is given. The two groups of mixing cabinets work alternately to meet the production efficiency requirements.

[0049] Of course, in order to improve production efficiency, the 12 sets of automatic precision feeding machines can be divided into two groups for feeding, with 6 in each group. At this time, it is divided into n≤6 and n greater than 6.

[0050] With the pre-feeding process after the transformation of this application, the mixing of industrial formulas is completed in advance through precise feeding equipment:

[0051] When the feeding level is ≤12: all formula levels are tested for chemical composition once (nicotine index is generally used here) and then an interval matching plan is generated. The tobacco frames of each grade are placed in 12 precise feeders according to the proportion, and the feeders are adjusted to ensure real-time feeding and mixing according to the industrial formula. After feeding, a secondary chemical composition test is carried out (nicotine, composite index sugar-alkali ratio or other controls can be used as needed here). Since all tobacco leaves are mixed into a full formula level after mixing, the intervals can be divided according to the size of the full formula storage area after testing, and the test results are subdivided into N intervals for storage. When out of the warehouse, the outbound delivery is matched according to the outbound quantity and interval conditions to form an outbound feeding unit. Taking the single-grade chemical composition matching as an example, the cargo position AN stores N interval tobacco leaves respectively, and the number of tobacco leaves in the warehouse is Na, Nb, Nc,...Nn, respectively, and the proportions are a%, b%,...,n% respectively.

[0052] Na / (Na+Nb+...+Nn)=a%

[0053] Nb / (Na+Nb+...+Nn)=b% ........

[0055] Nn / (Na+Nb+...+Nn)=n%

[0056] Set the outbound quantity to Z frames (generally, the number of frames that a pre-treatment cabinet can accommodate is about 30-36), and the outbound quantities of the corresponding levels are Za, Zb, ..., Zn. Then the corresponding outbound principles for interval matching are:

[0057] Za=Z*a%

[0058] Zb=Z*b% ..............

[0060] Zn=Z*n%

[0061] When the feeding level is ≥12, if the number of matching levels is large and exceeds the processing capacity of 12 feeders (this situation is rare, accounting for about 1 / 10, and can be divided into two mixed levels), all matching levels can be mixed multiple times, and then the proportion of each mixed level can be fed in proportion when feeding. Follow the principle of first matching single levels and then mixing multiple levels. That is, set the outbound quantity of levels A1, A2-An, the first level is outbound and prepared according to the interval ratio, the second level is outbound and prepared according to the interval ratio, and so on. After all levels are outbound, they form a preparation unit.

[0062] The prepared material units are taken out of the warehouse, and 4 precision feeders are used to feed the materials in order (when divided into multiple mixed grades, the feeders can be quantitatively adjusted to different flow rates according to the proportion of each grade for feeding).

[0063] Example 2

[0064] Using the data of the first large frame inspection after the first selection, a total of ny (a multiple of 36, with a maximum value of 432) frames are taken out at a time and placed in the preparation area according to n grade formulas, without considering factors such as the origin grade. When feeding, 12 frames are randomly selected for feeding, and placed in a cargo position after chemical testing. When feeding out of the warehouse, the same number of cigarette frames are fed to each cargo position according to the chemical composition. A feeding list is formed and the feeding is combined.

[0065] Step 1: Adopt the existing homogenization system solution, use the large frame inspection data after the first selection, form chemical inspection and physical formula units according to the grade formula, and ship them out to the pre-feeding preparation area (the number of shipments is a multiple of 36).

[0066] Step 2: Use 12 sets of automated precision feeders to evenly mix 12 frames from the preparation area each time, and then re-frame through a second online inspection.

[0067] Step 3: Using the second online test data, the graded blended formula tobacco leaves are classified according to the online test data and put into the formula library for preparation. Each time 12 frames of tobacco are put into a storage location, and the storage location is classified according to the online test results.

[0068] Step 4: Prepare materials in the recipe library. Using the second online test data, 36 frames (400kg per frame) of tobacco leaves are grouped and fed for the second time. After rehumidification, the materials are fed through 4 automatic and precise feeding machines for feeding;

[0069] Step 5: After the feeding is completed, the materials enter the pre-treatment mixing cabinet for storage and a cabinet switching signal is given. The two groups of mixing cabinets work alternately to meet the production efficiency requirements.

[0070] In this embodiment, all formula levels are chemically tested once to generate an interval matching plan, 36w boxes are selected at one time and warehouse processing is performed at the same time (144 / 288 / 432 can be selected here, and w can only be a number divisible by 36), 12 boxes are fed each time through the precision feeding machine (all at the same fixed speed), and secondary chemical composition testing is performed after feeding (nicotine, composite indicator sugar-alkali ratio or other adjustments can be used as needed here), and 12 boxes enter a preparation cargo position (at the same time, interval arrangement is performed in the cargo position, and the same partition interval range is set for each cargo position). After 3w feedings are completed, 36 / 3w boxes are taken from each of the 3w cargo positions when feeding, so that a uniform mix including 36w boxes can be formed, and the maximum deviation of the industrial formula feeding is 1 / 36w*100%.

[0071] When feeding, the selection of cigarette frames for each cargo position must be carried out according to the method of outbound feeding when the feeding level is ≥12. Due to the large number of cargo positions, the chemical composition combination of each cargo position can be considered centrally, and each cargo position can be divided into different partitions to achieve comprehensive consideration, complete the secondary feeding and preparation, and form a preparation unit after all levels are outbound. The preparation unit formed by outbound feeding can be outbound, and 4 precision feeding machines can be used to feed in order.

[0072] The process of this application can improve the uniformity of tobacco leaf mixing: by adopting this formula feeding method, the leaf beating and re-roasting pretreatment and pre-feeding process can realize the "two-level chemical inspection and matching" formula preparation mode, and the physical formula single small-level clustering grouping technology can be used to solve the problem of multi-level formula feeding, improve the accuracy of batch processing tobacco leaf grade formula, and achieve the purpose of no missing items in industrial formula. (Data: When the formula leaf beating and feeding is used, the feeding quantity is generally calculated by frame. The number of feeding frames is determined by the storage capacity of the rear-end leaf storage cabinet. The deviation is a whole frame, generally 400-500KG. Calculated based on 24 feeding stations, the uniformity difference may be 1 / 24=4.17%, which can be significantly reduced after the process is changed. Calculated based on 144 frames of feeding at a time, the difference is 0.7%, a reduction of about 3.47%, and there is almost no difference when feeding at a variable speed)

[0073] The process of the present application can also improve the uniformity of the chemical composition of the finished tobacco leaves: by adopting this formula feeding method, the large-scale frame inspection data after the first selection is used to carry out the formula combination of large batches of tobacco leaves for the first-level chemical inspection, and then the second online detection data is used to adjust the formula combination between the feeding units in the large batch of the second-level chemical inspection. When preparing materials in the formula library, the secondary reorganization of large batches of formula-grade tobacco leaves can be achieved, so that the difference between the nicotine mean values ​​of the tobacco leaves of several feeding units prepared at the same time is significantly reduced, thereby achieving the purpose of balancing the difference in nicotine values ​​between the feeding units, reducing the coefficient of variation of nicotine in the finished tobacco leaves, and improving the level of homogenization processing. (Data: After secondary blending, the nicotine variation coefficient was 2.47% after testing, which was a 48% decrease compared to the average nicotine variation coefficient of 4.75% for other tobacco leaves of the same grade. Simply using storage cabinets can reduce the nicotine variation coefficient by about 10%. Table 1 is the statistical results of nicotine data in the small unit process actually obtained by the applicant. Each level of storage cabinet can reduce the nicotine variation coefficient (CV value) and make the chemical composition mix more evenly). After the implementation of the overall process path, the nicotine variation coefficient can be effectively reduced by 10%-20%.

[0075]

[0076] The process steps of the present invention are clear and concise, and the operation is simple and easy to control, which is suitable for large-scale industrial production. After using this method, the tobacco leaf material will form a new process path of two inspections, three mixing cabinet mixing, and two precise feeding machines. It has processing capabilities such as "two inspections and three mixings, five-level assembly", and has adjustable multi-index homogenization feeding processing capabilities. By adopting this formula feeding method, the traditional leaf threshing and redrying pretreatment feeding process is moved forward to the pretreatment feeding and preparation link, and the process flow is optimized and reconstructed. The whole process of leaf threshing and redrying batch tobacco leaf processing from selection and preparation to assembly and feeding can be realized. The dynamic process can also ensure that the nicotine CV value of the tobacco leaf feeding unit in a large batch is highly consistent with the average nicotine CV value of the entire tobacco leaf in the large batch.

[0077] Possessing multi-index control capability: By adopting this formula feeding method, two-level chemical inspection control factors can be variable during material preparation, such as: nicotine, sugar-alkali ratio, color, spectrum and other control factor application combinations. At the same time, the control factors of each level of chemical inspection can also be set with a control weight ratio, ultimately achieving multi-dimensional internal component uniformity and precise control of large-module and multi-level module feeding.

[0078] This application involves a large number of professional terms in the field of leaf threshing and re-drying. The relevant professional terms shall be based on their meanings in this field and will not be explained one by one here.

[0079] Although the technical solutions of the present invention have been described and listed in detail, it should be understood that it is obvious to those skilled in the art to make modifications to the above embodiments or adopt equivalent alternatives. These modifications or improvements made without departing from the spirit of the present invention are within the scope of protection required by the present invention.
