Embodiment 1

[0020] like figure 1 As shown, the method for measuring the combustibility of tobacco leaves in this embodiment includes the following steps: (1) take more than 30 pieces of flue-cured tobacco leaves for moisturizing and stemming, and then put the flue-cured tobacco leaves into a 35°C blast drying oven to dry, and use a The pulverizer pulverizes the flue-cured tobacco leaves and sieves them through a 40-mesh sieve; (2) The sifted flue-cured tobacco leaves powder is placed in a constant temperature and humidity box with a temperature of (21-23) °C and a relative humidity of (57-63)% for equilibrium More than 48 hours; (3) Put the flue-cured tobacco leaf powder balanced in step (2) into the sample cup of the near-infrared spectrometer, so that the thickness of the flue-cured tobacco leaf powder in the sample cup is consistent and not less than 5mm, and the near-infrared spectrometer The flue-cured tobacco leaf powder in the sample cup is detected, and the near-infrared spectrum ...

Embodiment 2

[0022] The method for determining the combustibility of tobacco leaves in this embodiment includes the following steps: (1) Take more than 30 pieces of B2F flue-cured tobacco leaves, re-moisturize and stem them, then put the flue-cured tobacco leaves in a blast drying oven at 40°C for drying, and use a plant grinder after drying. Pulverize the flue-cured tobacco leaves and pass through a 40-mesh sieve; (2) place the sieved flue-cured tobacco leaves powder in a constant temperature and humidity box with a temperature of (21-23) °C and a relative humidity of (57-63)% for 48 hours to balance above; (3) put the flue-cured tobacco leaf powder after balance in step (2) into the sample cup of the near-infrared spectrometer, so that the thickness of the flue-cured tobacco leaf powder in the sample cup is consistent and not less than 5mm, and the near-infrared spectrometer is used to measure the sample cup. (4) Collect the near-infrared spectrum of the flue-cured tobacco powder, and use...

Embodiment 3

[0024] The method for measuring the combustibility of tobacco leaves in this embodiment includes the following steps: (1) take more than 30 pieces of flue-cured tobacco leaves C3F, re-moisturize and stem, then put the flue-cured tobacco leaves in a blast drying oven at 45°C to dry, and use a plant grinder after drying. Pulverize the flue-cured tobacco leaves and pass through a 40-mesh sieve; (2) place the sieved flue-cured tobacco leaves powder in a constant temperature and humidity box with a temperature of (21-23) °C and a relative humidity of (57-63)% for 48 hours to balance above; (3) put the flue-cured tobacco leaf powder after balance in step (2) into the sample cup of the near-infrared spectrometer, so that the thickness of the flue-cured tobacco leaf powder in the sample cup is consistent and not less than 5mm, and the near-infrared spectrometer is used to measure the sample cup. (4) Collect the near-infrared spectrum of the flue-cured tobacco powder, and use the multiv...

Abstract

The invention discloses a method for determining combustibility of tobacco leaf, which comprises the following steps: 1)removing stalk of tobacco leaf and drying under a proper condition, employing a multi-functional pulverizer for crushing, sieving the tobacco leaf powder; 2)placing a proper amount of tobacco leaf powder in a sample cup of a near-infrared spectroscopy, collecting its near infrared spectroscopy; 3)fitting the collected to the near infrared spectroscopy and the combustibility of tobacco leaf determined by a classic method, establishing a corresponding mathematics model; and 4)using a near infrared prediction model of the combustibility of tobacco leaf for analyzing near infrared spectroscopy of the unknown tobacco leaf so that combustibility data of the sample can be obtained. The method has the advantages of simple operation, labour saving and time saving, and batch detection adaption, can realize rapid and nondestructive analysis of combustibility of tobacco leaf, and provides simple and rapid data acquisition technology support for purchasing tobacco leaf, evaluating quality, and researching and developing the new product.

Description

technical field [0001] The invention relates to a method for measuring the combustibility, in particular to a method for measuring the combustibility of tobacco leaves. Background technique [0002] The physical characteristics of tobacco leaves refer to some physical characteristics that affect the quality of tobacco leaves and technological processing. They are an important part of tobacco leaf quality. index. Cigarettes are special consumer products. What people smoke is the gas produced after the tobacco leaves are burned. The combustibility of tobacco leaves is closely related to the harmful components contained in the smoke. The current smoking and health issues have attracted widespread attention, and people have also conducted a lot of research on many factors that affect the composition and content of harmful components in smoke. [0003] At present, the commonly used method for determining the flammability of tobacco leaves is: select 10 representative tobacco le...
