Description

Technical Field

[0001] The utility model relates to the technical field of flue-cured tobacco moisture regeneration, in particular to a flue-cured tobacco moisture regeneration and cooling device with water resource recovery. Background Art

[0002] Tobacco leaf rehydration is the process of rehydrating the freshly cured tobacco leaves through artificial rehydration and natural rehydration. The moisture content of the tobacco leaves should be kept at 16%-18% after rehydration, which is conducive to the smooth grading and purchase of tobacco leaves. The speed of natural rehydration is too slow, so a rehydration device is needed to speed up the rehydration.

[0003] After searching, a Chinese patent discloses a flue-cured tobacco dehumidifier (Announcement No. CN218999500U), including a base, a barrel body fixedly connected to the base, a wheel frame fixedly connected to the lower end of the base, a rotating shaft connected to the inside of the wheel frame through a bearing, a wheel fixedly connected to the rotating shaft, a brake mechanism provided on the base, a water outlet pipe fixedly connected to the lower end of the barrel body, a water outlet pipe slidably connected to the inside of the base, and a connecting pipe plugged into the inside of the water outlet pipe. The utility model provides a flue-cured tobacco dehumidifier, which is provided with a turntable, a limit block, a clamping block, a threaded rod and other components. By rotating the threaded rod, the threaded rod drives the clamping block on the limit block to slide into the clamping groove on the turntable, and the wheel can be limited to keep stable when placed, which solves the problem that the existing flue-cured tobacco dehumidifier is inconvenient to limit the wheel when in use, which easily leads to instability of the device when placed.

[0004] Although the above-mentioned search patent technology can prevent the occurrence of unstable equipment placement, the water generated by steam condensation during the rehumidification process cannot be directly discharged and recycled, resulting in a waste of water resources. Therefore, technical personnel in this field provide a flue-cured tobacco rehumidification and cooling device with water resource recovery to solve the problems raised in the above-mentioned background technology.
