AI Technical Summary

Problems solved by technology

Relative density, refractive index and other physical indicators have a single amount of information, and are not sensitive enough to monitor the quality of the blending process
The complicated pre-treatment and long analysis time of chromatographic analysis technology make it difficult to connect with actual production
The above-mentioned method is difficult to apply to the online real-time monitoring of the flavor and fragrance blending process

Embodiment 1

[0021] Such as figure 1 As shown, there are mainly the following process monitoring points in the blending process of flavors and fragrances for tobacco: fragrance base, material base preparation tank discharge, fragrance liquid, feed liquid preparation tank discharge and workshop storage tank discharge. Such as figure 2 As shown, sampling pipes are installed on the discharge pipes of the above-mentioned process monitoring points, and near-infrared optical fiber probes are installed behind the sampling pipes, and the probes are connected to near-infrared spectrometers through optical fibers. Such as figure 1 As shown, multiple near-infrared optical fiber probes at different monitoring points share a near-infrared spectrometer, and the near-infrared spectrometer is incorporated into the main control system of the spice kitchen through the data line. The near-infrared spectrometer control system is embedded in the main control system of the spice kitchen, and the near-infrare...

Abstract

The invention discloses an on-line monitoring device for preparing tobacco essence perfume. According to the on-line monitoring device, one or more process monitoring points are provided with sampling pipelines respectively; near infrared optical fiber probes are arranged behind the sampling pipelines respectively; a plurality of near infrared optical fiber probes at different process monitoring points share and are connected with a near infrared spectrometer; and the near infrared spectrometer is connected with a perfume kitchen master control system through a data line. The near infrared spectrum technology is applied to on-line real-time monitoring of the tobacco essence perfume preparation process. After establishing the on-line monitoring device and a model, a quantitative chemical index and a mahalanobis distance of a sample can be obtained in real time by scanning a spectrum of the sample on line and are compared with control requirements; and if abnormity occurs, the master control system alarms to prompt the technical personnel to search the reason.

Description

technical field [0001] The invention belongs to an on-line monitoring device and method for the blending process of flavors and fragrances for tobacco, and specifically uses near-infrared spectrum technology to online monitor the quality stability of the blending process of flavors and fragrances for tobacco. technical background [0002] In order to improve the smoking quality of cigarettes and endow cigarettes with characteristic aroma, a certain proportion of flavors and fragrances are generally added in the production process of shredded cigarettes. The spice kitchens of cigarette companies blend tobacco flavors and fragrances according to the recipe list and apply them on leaves or shredded tobacco. The quality stability of tobacco flavors and fragrances after blending is directly related to the quality stability of cigarette products. At present, the quality of the blending process of tobacco flavors and fragrances is mainly controlled by empirical process parameters, ...
