Device and method for identifying tobacco extract quality

Abstract

The invention discloses a device for identifying the tobacco extract quality. The device comprises: a sample bottle (1), which is equipped with a cover for sealing at the top, has one end connected toan air compressor (2) through an air pipeline (16), on which a flowmeter (3) is equipped to control the air velocity, and has the other end connected to one end of a detector (4) through an air inletpipeline (12); the detector (4), which has the other end connected to a gas collecting bottle (14) through a waste gas pipeline (13), and comprises a detection chip (5), which comprises a substrate (17), a gas sensitive layer (15), a heating electrode (6), a measuring electrode (7) and a heater (8); and a data collector (9), which has one end connected to the detector (4) and the other end connected to a data analysis system (11). The detection device and the identification and analysis method are pertinently suitable for identifying the tobacco extract quality with small difference.

Description

technical field [0001] The invention belongs to the field of tobacco industry application, and in particular relates to a device and method for identifying the quality of tobacco extracts. Background technique [0002] In the process of shredded cigarettes, in order to improve the processing performance and smoking characteristics of tobacco, it is usually added after the loosening and rehydration process. The added liquid contains tobacco extract after preparation, and tobacco extract is tobacco products. Key factors in the formation of style characteristics. Tobacco extracts are put into large-scale production after being tested and selected by scientific researchers. Due to the influence of environment, storage, long-distance transportation and other factors, some tobacco extracts will inevitably be contaminated by microorganisms and deteriorate. However, the tobacco extract itself is expensive, which increases the cost of the enterprise, and if such tobacco extract is n...

Problems solved by technology

Tobacco extracts are put into large-scale production after being tested and selected by scientific researchers. Due to the influence of environment, storage, long-distance transportation and other factors, some tobacco extracts will inevitably be contaminated by microorganisms and deteriorate. Tobacco extract itself is expensive, which increases the cost of the enterprise, and if such tobacco extract is not detected in time and used in cigarette products, it will have an important impact on product quality

[0003] At present, the detection of the quality of tobacco extracts is mainly carried out by sensory evaluation and gas chromatography-mass spectrometry. The sensory evaluation method is straightforward, but because it relies on manual evaluation, the method itself is not objective enough and lacks scientificity.

Gas chromatography-mass spectrometry equipment is cumbersome, and because the components of tobacco extract itself are relatively complex, using gas chromatography-mass spectrometry to detect the quality of tobacco extracts requires a lot of trouble in the sample pretreatment process, and the detection process is easily affected by other components. Interference will affect the test results, and the maintenance cost of the equipment is high, the operation is complicated, and special training is required for the operators of the test equipment

[0004] On the other hand, the detection of the quality of tobacco extract is different from the detection of other substances. The reasons are that 1. The components of tobacco extract are complex, containing many esters, alcohols, ketones, and aldehydes. Samples are not easy to distinguish; 2. The testing requirements for the quality of tobacco extracts are more stringent. After using the existing testing methods to determine that the samples with similar quality to the standard products are used for smoking, the smoking taste will be significantly different from that of the standard products. Therefore, tobacco The detection requirements for the quality of extracts are more stringent. Not only can the standard products with large differences be detected and distinguished from the samples to be tested, and the quality can be judged, but more importantly, the standard products with small differences can be detected and distinguished from the samples to be tested.
