Abstract

An apparatus for drying and conditioning tobacco leaves, including a heater for heating conditioning air for conditioning tobacco leaves after drying, a temperature controller for controlling the heater so that the temperature of the conditioning air becomes a preset temperature, an atomized water sprayer for cooling the conditioning air fed to the heater, a humidifier for humidifying the conditioning air, and a humidity controller for detecting the moisture content of the tobacco leaves after drying and conditioning and controlling the humidifier so that the moisture content of the tobacco leaves becomes a target moisture content. The humidity controller is so constructed as to control the humidifier on the basis of a wet-bulb temperature. Saving of heat energy can be attained, and because a cooling chamber is not needed, the apparatus can be made compact and it becomes easier to stabilize a target moisture content.
