technical field

The utility model relates to the technical field of flue-cured tobacco equipment, in particular to a solar-powered tobacco flue-cured room for waste heat recovery.

Background technique

The flue-cured tobacco room is an indispensable basic equipment in the production of flue-cured tobacco. After being roasted and prepared in the flue-cured tobacco room, the unique color, aroma, taste and shape of the flue-cured tobacco will appear, and it will become a high-quality raw material that meets the needs of the cigarette industry. The basic principle is that after the tobacco leaves are heated, the water in the tobacco leaves is discharged, and the water is vaporized and then discharged out of the flue-curing room, so that the tobacco leaves are yellowed and dried.

The existing tobacco hanging rack cannot be adjusted, which makes it inconvenient for users to hang and collect tobacco leaves. And solar energy resources cannot be effectively utilized, and the heat recovery and recycling in the tobacco flue-curing room cannot be used.

Utility model content

In order to overcome at least one defect of the above-mentioned prior art, the utility model provides a solar tobacco curing room with waste heat recovery, which has a simple structure, is convenient to use, effectively utilizes solar energy resources, and can recover and recycle heat.
