Kinetic analysis of changes in concentrations of tobacco constituents during heating

KATSUOKA T.; SAKAMOTO K.

Japan Tobacco Inc., Yokohama, Kanagawa, Japan

Heat treatment of tobacco represented by heating and steaming is of crucial importance in the tobacco industry because it influences the quality of cigarettes such as their aroma and taste. The rates of these changes depend on the temperature and the...

Kinetic analysis of changes in concentrations of tobacco constituents during drying

KATSUOKA T.; OSAKI E.; SAKAMOTO K.

Japan Tobacco Inc., Tobacco Science Research Center, Yokohama, Kanagawa, Japan

Reaction kinetics was applied to the estimation of changes in the concentrations of some constituents in tobacco cut-filler during drying. Nicotine, α-CBT and sugars related to the smell and taste of tobacco were chosen as the prime chemical species...

A drying model of tobacco stem expanding in air flow

SAKAMOTO K.; TSUCHIZAWA K.; KATSUOKA T.

Japan Tobacco Inc., Yokohama, Kanagawa, Japan.

A drying model was developed to simulate changes in the water content and the temperature of a cylindrical plant material, tobacco stem, which expands in air flow mixed with or without superheated steam. The model is characterized as follows: (1)...

Simulation model for conditioning and casing processes in a rotary cylinder

SAKAMOTO K.; UCHIDA S.; OGAWA T.; YOSHIMOTO K.

Japan Tobacco Inc., Manufacturing Technology R&D Division, Kanagawa, Japan.

The water content and the temperature of tobacco material in conditioning and casing processes affect the quality of tobacco products. It is necessary to clarify the mechanisms of the processes for improving quality and for designing the optimum...

The pore-size distributions and states of adsorbed water on tobacco cut-fillers

SAKAMOTO K.; NAKANISHI Y.

Japan Tobacco Inc., Yokokawa, Tokyo, Japan.

The physical states of water adsorbed on tobacco cut-fillers depend on the micro-structure of the tobacco tissue, and the physicochemical behavior of the water is quite different from that of bulk water. The behavior of adsorbed water affects the...
