Abstract
The invention relates to a determination method for a blending ratio of expanded cut tobaccos in cut tobaccos. The method comprises the following steps: a, balancing the cut tobaccos in an environment with the temperature of 22+/-1 DEG C and the humidity of 60+/-3% for 24 hours; then taking out cigarettes and taking out the cut tobaccos in the cigarettes; weighing and recording; recording the cut tobaccos as T; b, putting the cut tobaccos into a container with liquid nitrogen; agitating and taking out expanded tobaccos floated on the liquid surface; c, manually picking out the expanded cut tobaccos in the expanded tobaccos; balancing the expanded cut tobaccos into the environment with the temperature of 22+/-1 DEG C and the humidity of 60+/-3% for 24 hours; weighing and recording as W; and d, comparing the weighed expanded cut tobaccos W with the weight T of the cut tobaccos to obtain the blending ratio of the expanded cut tobaccos in the cut tobaccos. The invention provides a convenient and feasible method for separating the expanded cut tobaccos in the cut tobaccos and determining the blending ratio.
