Description

Technical Field

[0001] The utility model relates to the technical field of tobacco curing, in particular to a fully closed hot air circulation intensive curing room. Background Art

[0002] There are intensive tobacco leaf baking rooms, which have two hot air circulation channels. The channels are usually made of 160-300mm PVC plastic pipes, and there are also 400-500mm ducts made of bricks. This duct is specially designed for hot air circulation during the heating or constant temperature period of the baking process. There are gates in the duct to control the hot air circulation channel.

[0003] During the baking process, if it is in the heating or constant temperature stage, the gate of the hot air circulation channel (most gates are in the form of plug plates) must be opened to keep the air duct unobstructed. In the dehumidification stage, closing the gate and pausing the hot air circulation process is conducive to dehumidification, so that a large amount of moisture can be discharged smoothly, and the dehumidification effect will be better. When the dehumidification period ends and the heating or constant temperature period begins, the gate of the hot air circulation channel should be opened again to restore the unobstructed hot air circulation channel. This is a common baking process in intensive baking rooms with rising airflow.

[0004] In the past, the gates in the hot air circulation channel were opened or closed manually. Since the dehumidification and heating or constant temperature operation in the baking room are frequently performed alternately, the manual operation of the gates is very intensive and sometimes cannot keep up with the dehumidification action, resulting in poor dehumidification effect and affecting the baking quality. In order to improve the baking quality, the opening or closing of the gates in the hot air circulation channel must be automatically followed by the dehumidification action, and it is very necessary to realize the automatic control of the opening or closing of the hot air circulation channel.
