Problems solved by technology

[0011] At present, there is no relevant standard for the determination of volatile content in tobacco, but due to the large differences in the test conditions of moisture, ash and volatile content, the tests of these three indicators have always been independent and carried out in sequence. , the whole test process takes a long time and the work efficiency is low, which cannot meet the requirements of fast on-line analysis in the industrial field

Embodiment 1

[0024] Such as figure 1 As shown, a rapid industrial analysis method for tobacco of the present invention directly uses thermogravimetric analysis (TGA), the instrument generates a complete TG curve, and simultaneously obtains the moisture value, ash value, and volatile content value in the tobacco through the TG curve And fixed carbon value.

[0025] The specific operation includes the following steps:

[0026] (1) Tobacco samples are crushed and sieved to obtain tobacco dust. Weigh 10 mg of tobacco dust and place it in the sample crucible of the thermogravimetric analyzer. In an inert gas atmosphere (flow rate 100mL / min), the temperature is raised to 105 at 20℃ / min. ℃, and keep it for 8min. At this time, the weight loss percentage of the sample in the TG curve is the moisture value of the tobacco sample.

[0027] (2) Continue to program the temperature from 105°C to 950°C at 20°C / min under an inert gas atmosphere (flow rate 100mL / min) and keep it for 5 minutes. At this time, the w...

Abstract

The invention discloses a tobacco rapid industrial analysis method. According to the invention, a thermogravimetric analysis method replaces a drying oven method and a Muffle furnace method which are used for traditional proximate analysis, and a moisture value, an ash content value, a volatile matter value and a fixed carbon value of a tobacco sample are obtained through a TG curve at the same time. The method has the advantages of small sample amount for detection, short analysis time, low cost, simple operation and accurate experimental result, and is a tobacco rapid industrial analysis method capable of meeting rapid on-line analysis requirement of industrial current environment.

Description

1. Technical Field [0001] The invention relates to an analysis method, in particular to a rapid industrial analysis method of tobacco, belonging to the field of tobacco analysis. 2. Background technology [0002] Industrial analysis originated from the coal industry, and then expanded to other biomass material analysis indicators, usually including moisture, ash, volatile and fixed carbon analysis and testing of these four values. Among them, moisture, ash, and volatile content are all calculated through experiments, and fixed carbon is calculated through the use of the above three test results. That is to say, the conventional industrial analysis test should have at least the above three test processes, and the industrial analysis of the sample should be completed after obtaining the moisture, ash, volatile content in the sample and calculating the fixed carbon value. [0003] Tobacco is a special kind of biomass, and its industrial analysis indicators are also very important. T...
