Intelligent tobacco leaf bulk curing barn

Abstract

The invention discloses an intelligent tobacco leaf bulk curing barn. The intelligent tobacco leaf bulk curing barn comprises a baking chamber, outer chambers, a heating chamber and a wind chamber, wherein the wind chamber is located above the heating chamber, the wind chamber is communicated with the heating chamber through a circulating draught fan which not only can rotate forward but also canrotate backward, the wind chamber and the heating chamber are separated from the baking chamber through a same partition wall, the outer chambers are located on the outer walls of a front wall and rear wall of the baking chamber, the heating chamber is internally provided with a heater, the bottom of the partition wall is provided with a first ventilation port communicated with the bottom of the heater, and the top of the partition wall is provided with a second ventilation port. The intelligent tobacco leaf bulk curing barn has the advantage of significantly improving the baking quality of tobacco leaves.

Description

technical field [0001] The invention relates to the technical field of tobacco curing, in particular to an intelligent intensive tobacco curing barn. Background technique [0002] In recent years, with the intensification of flue-cured tobacco production and the development of large-scale planting models, as well as the continuous increase in fuel prices and labor costs, intensive curing barns have been widely used and promoted. The baking principle of the intensive barn is that under the high smoke density, through forced ventilation, the hot air in the heating room, under the action of mechanical power such as a fan, heats the tobacco leaves evenly and takes away the moisture, and continuously heats and dries the tobacco leaves. The basic characteristics of the cycle process are that the smoke density is usually 2-3 times that of ordinary barns, forced ventilation, hot air circulation, and temperature and humidity control. Existing dense barns can generally be divided int...

Problems solved by technology

[0003] However, there is a temperature difference of 5°C between the top table and the bottom table in both the ascending-air-flow curing barn and the descending-air-flow barn, which leads to inconsistencies in the curing process of the tobacco leaves, and it is impossible to make the whole curing process complete. Overall availability of tobacco leaves is poor
