Embodiment 1

[0141] 1.1 Sample preparation

[0142] The upper tobacco and lower tobacco from Sanming, Fujian were selected, and the tobacco leaf material was cut into shreds and then equilibrated in a constant temperature and humidity room for 48 hours, and adjusted to a moisture content of 23% on a wet basis for use. The two tobacco samples had similar three-dimensional dimensions: average length 2 cm, average width 0.1 cm, and average thickness 0.018 cm.

[0143] The surface area A of the tobacco sample can be calculated by the following formula:

[0144]

[0145] In the formula, m (kg) is the initial mass of shredded tobacco, without considering the shrinkage effect of shredded tobacco during the drying process. The initial mass of shredded tobacco in this patent is 2kg, A s (m 2 ) is the surface area of ​​a single tobacco, V s (m 3 ) is the volume of a single cut tobacco, ρ t (kg·m -3 ) is the true density of cut tobacco. According to the three-dimensional size of the tobacc...

Abstract

The invention relates to a roller drying experimental device and a method for establishing a tobacco roller drying REA model. The roller drying experimental device comprises a roller, wherein a hole is arranged on the roller, and the hole is located on a rotation axis of the roller; and a sampling device which can get in and out of the roller cavity of the roller. The roller drying experimental device can be used for detecting physical property parameters in a tobacco drying process, further establishing the tobacco roller drying REA model and providing the good tool for research of tobacco drying behaviors.

Description

technical field [0001] The invention belongs to the field of material drying treatment, in particular to a drum drying experimental equipment and a method for establishing a tobacco drum drying REA model. Background technique [0002] In modern large-scale cigarette industrial production, drum drying equipment is widely used for drying and dehydrating tobacco materials. Drying and dehydration is a key heat-humid link in the processing of tobacco materials, which runs through the entire processing process of tobacco leaf raw materials from post-harvest primary roasting, threshing and redrying to silk making. The main purpose of drying tobacco is to remove a specific amount of moisture from the tobacco, enabling the tobacco to meet packing density requirements while also improving the organoleptic quality of the tobacco. During the tobacco drying process, changes in the temperature and humidity of the tobacco have a significant impact on the physical quality and sensory quali...
