A method for directly measuring and evaluating the effect of online feeding or drying

Abstract

The present invention relates to a method for directly measuring and evaluating the effects of online feeding or drying. Tobacco leaf samples are extracted from a first set position in online production, a portion of which is loaded into a perforated device and then returned to the production line. After the production material emerges from the drum, the perforated device is removed, and the tobacco leaf sample within the perforated device is tested for index data to obtain subsequent index data. The subsequent index data is compared with the initial index data to obtain the precise index data changes for the same tobacco leaf sample before and after the processing step. This technical solution enables precise evaluation of feeding effects, drying effects, residence time, and other factors, completely eliminating the uncertainty introduced by tobacco leaf samples. Furthermore, drying tests can be conducted simultaneously for different incoming material moisture levels, significantly reducing the number of tests, reducing the impact of the tests on large-scale production, and minimizing the risk of the tests.

Description

Technical Field

[0001] The invention belongs to the technical field of online detection, and in particular relates to a method for directly measuring and evaluating online feeding or drying effects. Background Art

[0002] Currently, it is difficult to accurately evaluate the online feeding effect, residence time, etc. The main reason is that tobacco leaves are agricultural products, and the tobacco raw materials in the same batch of formula tobacco leaves are also different. Therefore, the comparativeness of sampling evaluation in the online process is not strong.

[0003] In this case, there is a large difference between the online detection data and the actual data. In order to ensure the quality of the product, the only way is to increase the detection frequency, which leads to a large workload and also poses a quality detection risk. Summary of the Invention

[0004] The purpose of the present invention is to provide a method for directly measuring and evaluating the effect of online feeding or drying, so as to solve the problem that the current online sampling evaluation has low comparability and quality inspection risks.

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

[0006] A method for directly measuring and evaluating the effect of online feeding or drying of fiber, comprising the following steps:

[0007] S1. Extract tobacco leaf samples from the first set position of online production and place part of the tobacco leaf samples into a device with holes;

[0008] S2. Calculate or mark the second set position to which the tobacco leaves at the first set position move when loaded into the perforated device, and place the perforated device at the second set position;

[0009] S3, detecting the index data of the remaining tobacco leaf samples in step S1 to obtain initial index data;

[0010] S4. After the production material comes out of the drum device, the perforated device is taken out, and the index data of the tobacco leaf sample in the perforated device is tested to obtain subsequent index data;

[0011] S5. Compare the subsequent index data with the initial index data to obtain the accurate index data changes of the same tobacco leaf sample before and after the processing step.

[0012] Furthermore, in step S4, it also includes using the indicator data detected by the current online sampling technology to obtain conventional indicator data.

[0013] Furthermore, the same parameter data in the initial index data, subsequent index data and conventional index data are selected for comparison, that is, the difference Δ1 between the parameter data in the conventional index data and the parameter data in the initial index data, and the difference Δ2 between the parameter data in the subsequent index data and the parameter data in the initial index data. If Δ1 is less than or equal to Δ2, it indicates that the conventional detection accuracy meets the design requirements; if Δ1 is greater than Δ2, it indicates that the conventional detection accuracy does not meet the design requirements.

[0014] Furthermore, the device with holes in step S1 is a container with mesh holes.

[0015] Furthermore, the container with mesh is flat or spherical and can be opened to fill with tobacco leaf samples.

[0016] Furthermore, in step S2, the second set position is calculated by calculating the time difference between extracting the tobacco leaf sample and preparing to put the perforated device back into the production line, and the speed of the conveyor belt of the production line, to calculate the instantaneous position of the extracted tobacco leaf sample on the production line, that is, the second set position.

[0017] Furthermore, the index data in step S3 at least include the moisture and chemical composition content data of the tobacco leaves.

[0018] The beneficial effects of the present invention are:

[0019] This technical solution places the container with a perforated device in the bulk production of tobacco leaves during online production, and enters the feeding process or other production process together with the bulk production materials, and then follows the bulk production materials out of the drum equipment. Before entering, the moisture content, chemical composition content and other data of the tobacco leaves are measured, and then the corresponding indicators are tested after the tobacco leaves come out of the container. This allows for an accurate comparison of the indicators of the same tobacco leaf sample before and after the processing process, and allows for accurate evaluation of the feeding effect, drying effect, residence time, etc., completely eliminating the uncertainty brought by the tobacco leaf samples, and allowing for simultaneous drying tests of different incoming material moisture levels, greatly reducing the amount of testing, reducing the impact of the test on bulk production, and minimizing the test risk. DETAILED DESCRIPTION

[0020] The technical solutions of the present invention are described in detail below through examples. The following examples are merely exemplary and can only be used to explain and illustrate the technical solutions of the present invention, and cannot be interpreted as a detailed description of the technical solutions of the present invention.

[0021] This technical solution provides a method for directly measuring and evaluating the effect of online feeding or drying, comprising the following steps:

[0022] First, prepare a perforated device. In this application, the perforated device is a container with mesh holes, either flat or spherical, that can be opened to accommodate a tobacco sample. In other embodiments of this application, the perforated device can be any suitable device, preferably made of metal, to facilitate balancing certain parameters of the tobacco sample within the perforated device with the tobacco produced online, such as moisture and temperature. The shape of the perforated device can be any shape, as long as it ensures the operation of online production without hindering it.

[0023] S1. Extract tobacco leaf samples from the first set position of online production. The first set position here is usually a fixed sampling position. Load part of the extracted tobacco leaf samples into a device with holes, and the remaining part of the tobacco leaf samples is used for subsequent testing to obtain initial indicator data.

[0024] In the technical solution of the present application, tobacco leaf samples can be extracted at a first set position according to a set plan, such as at specific time intervals, and loaded into a corresponding perforated device. At this time, an interval sampling sequence is formed to detect the index data of tobacco leaves in different periods of online production.

[0025] S2. Calculate or mark the second set position to which the tobacco leaves at the first set position move when loaded into the perforated device. Specifically, after the tobacco leaf sample is extracted at the first set position, the tobacco leaves or shredded tobacco produced online continue to move forward driven by the conveyor belt. After running for the set time, the distance they run is the second set position, and this is marked.

[0026] Another method is to determine the second set position by calculation, that is, the time from extracting the tobacco leaf sample from the first set position to loading the tobacco leaf sample into the perforated device and returning the perforated device containing the tobacco leaf sample to the production line. This time is multiplied by the speed of the production line conveyor belt to obtain the moving distance of the conveyor belt. The perforated device is placed back to the production line at this distance as the second set position. In this application, the second set position is preferably calculated to eliminate the differences caused by different speeds of loading tobacco leaf samples.

[0027] S3. The remaining tobacco leaf samples in step S1 are tested to obtain initial index data. In this application, the initial index data is actually the test data of online testing using existing technology. In existing technology, the test data is used to monitor production.

[0028] S4. The perforated device placed in the production line enters the feeding process or other production process together with the mass production materials, and is then taken out of the drum equipment along with the mass production materials. The tobacco leaves taken out from the perforated device are tested to obtain subsequent indicator data.

[0029] At the same time, based on existing conventional technology, conventional index data are detected using existing conventional online sampling technology to obtain conventional index data. The conventional sampling detection of this part may be different in different production lines. Therefore, it can be processed according to the actual detection design of the producer without the need for a separate design. Therefore, the applicant's description of this point is clear to those skilled in the art.

[0030] S5. Compare the subsequent index data with the initial index data to obtain the accurate index data changes of the same tobacco leaf sample before and after the processing step.

[0031] The same parameter data in the initial index data, subsequent index data and conventional index data are selected for comparison, that is, the difference Δ1 between the parameter data in the conventional index data and the parameter data in the initial index data, and the difference Δ2 between the parameter data in the subsequent index data and the parameter data in the initial index data. If Δ1 is less than or equal to Δ2, it indicates that the conventional detection accuracy meets the design requirements. If Δ1 is greater than Δ2, it indicates that the conventional detection accuracy does not meet the design requirements.

[0032] In other embodiments of the present application, the test results of tobacco leaf samples in different perforated devices within a time period may be averaged to obtain an average index data, which is then compared with the average value of the conventional index data within the same time period.

[0033] In an embodiment of the present application, the index data includes at least the moisture and chemical composition content data of the tobacco leaves.

[0034] Through actual tests, this technical solution is also applicable to online parameter tests. For example, when conducting tobacco drying tests, tobacco leaves with different moisture contents can be loaded into the container separately and placed into the drying drum for drying. Drying tests with different moisture contents of incoming materials can be carried out simultaneously, which greatly reduces the amount of tests, reduces the impact of tests on large-scale production, and minimizes the test risks.

[0035] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should fall within the scope of protection of the present invention.
