Abstract

The invention belongs to the technical field of tobacco detection, and particularly relates to a sample pretreatment method for near-infrared detection of finished tobacco lamina, which comprises the following steps: sample selecting; primary crushing: crushing a finished tobacco strip sample until the particle size is less than 3mm; drying: drying the finished tobacco strip sample subjected to primary crushing until the water content is 9.0-10.5%; secondary crushing: continuously crushing the dried finished tobacco strip sample until the particle size is less than or equal to 0.425 mm; and sample balancing: balancing the finished tobacco lamina sample subjected to secondary crushing for 30 minutes at constant temperature and humidity in an environment of 18-26 DEG C and 40-60% RH (Relative Humidity). The pretreatment method is short in time consumption and high in efficiency, and chemical properties of the prepared sample meet related detection requirements.

Description

technical field [0001] The invention belongs to the technical field of tobacco detection, and in particular relates to a sample pretreatment method for near-infrared detection of finished tobacco sheets. Background technique [0002] At present, there is no uniform standard for the pretreatment methods of near-infrared detection samples of finished cigarettes in the tobacco industry, but most of them have problems such as long time-consuming, high consumption of manpower and material resources, and low efficiency.
