New-type tobacco flue-curing room and the tobacco flue-curing process

Abstract

The new-type tobacco flue-curing room has tobacco racks in the inner walls for arranging tobacco leaves; boiler outside the room with sealed flue on the top, re-moistening pot on the boiler cover and boiler tubes on the sides; and the boiler tube has one end extending into the room, the other end connected to the flue and wind distributing boards on the upper side. Tobacco leaves arranged on the racks are flue-cured in three stages under controlled temperature and humidity and the flue-cured tobacco leaves the re-moistened directly to produce high quality tobacco leaf. The method of the present invention is safe and reliable and results in high quality and yield of tobacco leaf.

Description

technical field [0001] The invention relates to a novel tobacco curing room and a method for curing tobacco leaves. Background technique [0002] The flue-cured tobacco room and the flue-cured tobacco oven are the necessary technical equipment for the production of flue-cured tobacco. At present, the flue-cured tobacco rooms used in flue-cured tobacco production are all old-style flue-cured rooms, no matter whether they are of the ascending airflow type or the airflow descending type. The smoking rooms occupy a large area , it is also necessary to set up a resurgence site and a smoking room alone; when the old-style tobacco leaves are baked, the tip of the tobacco is at the bottom and the stem is at the top. The part flows back from the leaves to the main veins. After baking, the main ribs are very thick, the thickness of the leaves is uneven, and the quality is poor. The top-quality tobacco only accounts for 15%, and the medium-level tobacco accounts for 75%, and the yield ...

Problems solved by technology

[0002] The flue-cured tobacco room and the flue-cured tobacco oven are the necessary technical equipment for the production of flue-cured tobacco. At present, the flue-cured rooms used in the production of flue-cured tobacco are all old-style flue-cured rooms, no matter whether they are of the ascending airflow type or the airflow descending type. The smoking rooms occupy a large area. , it is also necessary to set up a resurgence site and a smoking room alone; when the old-style tobacco leaves are baked, the tip of the tobacco is on the bottom, and the stem is on the top. The part flows back from the leaves to the main veins. After baking, the main ribs are very thick, the thickness of the leaves is uneven, and the quality is poor. The top-quality tobacco accounts for only 15%, and the medium-sized tobacco accounts for 75%, and the yield is low.

The old-style tobacco flue-cured room has been used for a long time, the technology is outdated, the labor intensity is high, the operation technology is not easy to master, and there are many factors restricted by natural conditions.

The price of flue-cured tobacco ovens is relatively high, which is difficult for Chinese tobacco farmers to accept. The backwardness of flue-cured tobacco baking equipment seriously restricts the production of flue-cured tobacco in my country
