Title:
METHOD FOR ESTIMATING SWELLING PROPERTY OF LEAF TOBACCO STEM
Document Type and Number:
WIPO Patent Application WO/2019/004003
Kind Code:
A1
Abstract:
Provided is a method with which it is possible for a swelling property of a leaf tobacco stem after the leaf tobacco stem is subjected to a swelling process, to be estimated prior to execution of the swelling process. This method includes: a step of irradiating the stems of leaf tobacco prior to the swelling process with visible light and near infrared light having a wavelength of 400 nm to 2500 nm, and measuring a transmission/absorption spectrum or a diffusion/reflection spectrum; and a step of using the measured transmission/absorption spectrum or diffusion/reflection spectrum to calculate an estimated value of the swelling property after the swelling process, from a calibration model created in advance.
