Embodiment 1

[0029] According to the method for detecting the flavoring uniformity of shredded tobacco based on the principal component analysis method established in the present invention, the drum flavoring process of a certain brand in the silk making process of a certain production plant is tested and analyzed under different production process conditions, and the uniformity of flavoring is tested. The results guide the optimization of the process parameters of the silk production line. The specific test steps are:

[0030] a. Sample preparation:

[0031] Sample 1: The process parameters of the aromatization process are set as follows: flow rate 8000kg / h, atomization medium air pressure 0.3Mpa, drum speed 9r / min, and aromatization ratio 0.33%. Sampling method: After the equipment is running stably, 20 cut tobacco samples are continuously taken from the drum flavoring outlet every 1 minute, each sample is 10g, and placed in a plastic sealed bag.

[0032] Sample 2: The process paramete...

Embodiment 2

[0046] The method for detecting flavoring uniformity of shredded tobacco based on principal component analysis established according to the present invention is used for comparative analysis of flavoring uniformity of different flavoring methods (thread drum flavoring, laboratory artificial spray flavoring). The specific test steps are:

[0047] Sample preparation:

[0048] Sample 1: Silk thread made by a certain production plant, in the normal production process of a certain brand, set according to the normal process standard parameters, the process flow rate is 8000kg / h, the air pressure of the atomizing medium is 0.3Mpa, the drum speed is 9r / min, and the fragrance is set The ratio is 0.33%. After the equipment is running stably, 20 samples are continuously taken from the outlet of the aromatizing drum every 1 minute, 20g of each sample is taken, and placed in a plastic sealed bag.

[0049] Sample 2: For the same brand of shredded tobacco, all the processing procedures of ...

Abstract

The invention discloses a method for detecting the flavoring uniformity of cut tobacco based on a main component analysis technology. The method comprises the following steps: (1) preparing samples: uniformly taking samples by time or position from the flavoring outlet of a cut cigarette making line; (2) placing every sample in a brown headspace bottle, adding an internal standard solvent, and screwing bottle caps to seal the bottles; (3) detecting the content of volatile and semi-volatile components in every sample in a headspace-gas chromatograph/mass spectrometer (HS-GC/MS) full-scanning manner, performing mass spectrum database retrieval to achieve qualitative diagnosis, and performing quantification through an internal standard technology; (4) performing dimension reducing processingon the detection data of every sample through a PCA main component analysis technology, and projecting the data in a two-dimensional plane or a three-dimensional space; and (5) drawing a PCA map by using computer software, and detecting the flavoring uniformity of the cut tobacco according to the discrete degree of distribution of data points. The method provides a scientific and intuitive methodfor evaluating the flavoring uniformity of the cut cigarette, and can be used for detecting the flavoring uniformity of cut tobacco in different cut tobacco flavoring devices or different flavoring processes.

Description

technical field [0001] The invention relates to the technical field of tobacco manufacturing, in particular to a method for detecting the flavoring uniformity of shredded tobacco based on a principal component analysis method. Background technique [0002] During the cigarette manufacturing process, the shredded tobacco and shredded stalks are the key processes in the shredded tobacco production line. The main function is to evenly spray the essence into the shredded tobacco or shredded stalks in a certain proportion. The uniformity of flavoring directly affects the quality of cigarettes. Consistency of mass and its pumping qualities. At present, the flavoring uniformity of the cigarette factory’s shredded production line is generally monitored online through the flavoring accuracy index, but the flavoring accuracy is more to measure the matching of shredded tobacco and flavoring materials in the flavoring process. The uniformity of actual aromatization cannot be accurately...
