Definitions
- the dryer zones 22, 24, 26, 28 and 30 have a plurality of jet tubes 54 which are in flow communication with the pressure plenum 52. Jet tubes 54 force heated air downward onto the tobacco bed 12 with minimal disturbance of tobacco 12 yet causing an even drying of the tobacco throughout the tobacco bed and preventing deviation of moisture content throughout the bed depth. Accurate drying of the tobacco material is required because of pyrazine generation, removal of harsh volatiles and improved machinability of the leaf. Drying of the tobacco material must be closely monitored due to the drying of the heavy casing which is applied prior to this process, as improper drying may harden the casing and cause the tobacco leaf to curl.
- pyrazine formation remains fairly constant while drying at about 248°F (120°C) even though the drying time is reduced from more than minutes to 90 seconds.
- a reduction in total drying time utilizing a process and apparatus such as described herein may be accomplished while still achieving uniformity in redrying of the tobacco to about 5% moisture content .
