Method and system for detecting quality of tobacco slice

Abstract

The invention discloses a method and a system for detecting the quality of a tobacco slice. The method comprises the following steps of: performing microwave moisture detection on a tobacco slice to be stored into a warehouse by using a corrected microwave moisture instrument; judging whether the moisture content detected by the corrected microwave moisture instrument accords with a moisture content normal range of the technological requirement; if so, determining that the moisture content of the tobacco slice to be stored into the warehouse is qualified, otherwise, detecting the moisture content of the tobacco slice to be stored into the warehouse by using an oven method; judging whether the moisture content of tobacco slice to be stored into the warehouse, which is detected by the oven method, accords with the moisture content normal range of the technological requirement; and if so, determining that the moisture content of the tobacco slice to be stored into the warehouse is qualified, otherwise, determining that the moisture content of the tobacco slice to be stored into the warehouse is unqualified. By the method and the system, compared with the time needed when the moisture content is detected by the oven method, the time needed when the moisture content of the tobacco slice to be stored into the warehouse is detected by using the corrected microwave moisture instrument is reduced greatly, so the quality of a large number of tobacco slices to be stored into the warehouse can be detected, and unqualified tobacco slices can be prevented from being stored into the warehouse.

Description

technical field [0001] The present invention relates to the field of measurement and detection, and more specifically, to a method and system for detecting the quality of tobacco sheets. Background technique [0002] In the prior art, the inspection of the moisture content of laminar tobacco usually depends on the photosensitive judgment of the inspector when it is put into storage. When an obviously unqualified laminar tobacco is found, the oven method is used for detection. [0003] The process of detecting the moisture content of laminar tobacco by oven method is as follows: [0004] When testing the moisture content of the sample, first turn on the power of the oven, set the temperature at 100°C, start preheating, and start the test after the temperature rises to 100°C and stabilizes. The specific steps of the test are: use a sample box with known dry mass to weigh 5-10g of the crushed sample, weigh and record the weight of the sample, put it in the oven, the sample box...

AI Technical Summary

Problems solved by technology

[0005] It can be seen from the method of detecting moisture content by the oven method that it has disadvantages such as long detection time, low efficiency, small number of samples, damage to samples, and easy missed and false detections.
