Description

Technical Field

[0001] The utility model relates to the technical field of tobacco moisture testing, in particular to a tobacco moisture testing system based on a semi-automatic drying method. Background Art

[0002] The moisture content of cut tobacco refers to the degree of moisture in cut tobacco, expressed as a percentage. It is numerically equal to the ratio of the mass of moisture in cut tobacco to the mass of cut tobacco. For cigarette manufacturers, the moisture content of cut tobacco during production is a key indicator.

[0003] At present, the testing room of the cigarette factory usually uses the oven method and the near infrared method to determine the moisture content of cut tobacco. Among them, the oven method is a method specified by the national standard, which is a quantitative standard for calibrating the near infrared moisture meter and the accurate moisture of the actual sample. The usual method is to detect the moisture value of the sample at a workstation, take three bags of samples, and place them in six sample boxes in parallel to complete the test, and finally calculate the average value to obtain the moisture value of the workstation.

[0004] Taking Table 1 below as an example, the moisture value of a sample at a workstation determined by the oven method is shown in the table:

[0005] Table 1

[0006]

[0007] There are two methods for calculating moisture value in the oven method:

[0008] Calculation method (1)

[0009] Use artificially marked sample boxes (1, 2, 3, 4, 5, 6), weigh these sample boxes in turn and record the weight data (A, B, C, D, E, F), put the samples into the corresponding sample boxes in turn, weigh them, and record the weight data (A1, B1, C1, D1, E1, F1). After drying in an oven for 2 hours, weigh them in turn and record the weight data (A2, B2, C2, D2, E2, F2), and finally calculate the moisture value.

[0010] Calculation method (2)

[0011] Use artificially marked sample boxes (1, 2, 3, 4, 5, 6), weigh these sample boxes in turn and record the weight data (A, B, C, D, E, F), and the weight data obtained by the balance weighing is transmitted to the corresponding window position of the software; then put the samples into the corresponding sample boxes in turn, weigh them, and record the weight data (A1, B1, C1, D1, E1, F1), and the weight data obtained by the balance weighing is transmitted to the corresponding window position of the software. After drying in an oven for 2 hours, weigh and record the weight data (A2, B2, C2, D2, E2, F2) in turn, and finally calculate the moisture value.

[0012] However, the above two methods for calculating moisture value have the following defects:

[0013] The above calculation method (1): three weighings (respectively weighing the sample box without samples, the sample box with samples, and the sample box with samples after 2 hours of drying) must manually select six sample boxes in a sequential sequence. The weight of the sample box after the samples are loaded and the weight of the sample box after drying must correspond to the sequence of the sample boxes. If there is an error in the sequence of the whole process, the final moisture value will be calculated incorrectly.

[0014] The above calculation method (2): Although this method uses computer software to automatically obtain weighing data and transmit it to the corresponding software window, the weighing sequence of the three steps still needs to correspond one by one. This method has only been improved in terms of data recording and calculation, but the order of the entire process must be guaranteed to be correct.

[0015] It should be understood that the above example is only an experimental measurement of moisture at one workstation. In actual work, there are often scenarios where moisture at several workstations is measured simultaneously. The weight of these simultaneous sample boxes increases exponentially, and the requirements for the entire measurement process increase exponentially. Not only does it consume a lot of manpower to check, it is also prone to errors. Utility Model Content

[0017] The present application aims to solve one of the problems in the background technology. The technical solution adopted by the present utility model is to provide the following technical solutions to achieve the above-mentioned purpose and other related purposes:
