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 drum drying experimental equipment and a method for establishing a tobacco drum drying REA model. Wherein, the drum drying experimental equipment includes: a drum, the drum is provided with a hole, and the hole is located on the rotation axis of the drum; and a sampling device, the sampling device can enter and exit the cylinder cavity of the drum through the hole. The drum drying experimental equipment can be used to detect the physical parameters during the tobacco drying process, and further establish the tobacco drum drying REA model, which provides a good tool for studying tobacco drying behavior.

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...
