Embodiment 1
[0047] The Yunyan (purple) thin plate module of Kunming Cigarette Factory was selected as the test raw material, and the tobacco samples were taken at different leaf storage times at the entrance of the feeding process, the outlet of the feeding process, and the leaf storage process;
[0048] At the entrance of the feeding process, samples were taken at intervals of 10 minutes, and 3 parallel samples were taken each time (100g / time), and a total of 10 samples were taken; sealed and refrigerated respectively, pending GC-MS detection;
[0049]At the outlet of the feeder, samples are taken at intervals of 10 minutes, and 6 parallel samples (100g / piece) are taken each time. After the 100g samples are fully mixed, 15g of tobacco leaf samples are weighed by the quartering method (the sample weight is accurate to 0.0001g); Of the 6 parallel samples at each time series point, 3 of them were eluted by the extraction method, and the remaining 3 were eluted by the extraction method; Afte...

The invention discloses a method for measuring absorption rate and effective absorption ratio of feed liquid of a flue-cured tobacco lamina. The method comprises the following steps: processing a sample before testing, digesting the sample, extracting the sample, carrying out CS-MS (Gas Chromatography-Mass Spectrometry) detection, expressing the detection result, and calculating. According to the invention, a method for effectively separating feed liquid on the surface of the flue-cured tobacco lamina from the feed liquid in the flue-cured tobacco lamina is established; the process of the flue-cured tobacco lamina absorbing the feed liquid is quantified; a concept of the absorption rate of the feed liquid in the flue-cured tobacco lamina is proposed, and the calculation method is established; the new basis is provided for adjusting and optimizing feeding and tobacco storing technological parameters; the concept of full absorption of the feed liquid is quantified; the concept of effective absorption ratio of the feed liquid in the flue-cured tobacco lamina is proposed; and the calculation method of the effective absorption ratio of the feed liquid in the flue-cured tobacco lamina is established.
Description
technical field [0001] The invention belongs to the technical field of cigarette technology, and in particular relates to a method for accurately measuring the liquid absorption rate and effective absorption rate of sheet tobacco, which is applied in a cigarette production and feeding process or a storage process. Background technique [0002] Tobacco dosing is an important process in the cigarette shredding process. The main task is to accurately and evenly apply the prepared feed liquid to the cigarette according to the product formula. The leaf storage process is to provide the space and time for the laminar tobacco to fully absorb the feed liquid, so that the feed liquid can play the functions of seasoning, flavoring, moisturizing, mildew prevention, and combustion support to a certain extent. [0003] At present, the evaluation of the feeding effect mainly focuses on several aspects: [1] Judging the uniformity by the feeding accuracy, that is, the fluctuation of the rat...
