Humidifying system of bulk curing barn

Abstract

The invention discloses a humidifying system of a bulk curing barn. The humidifying system comprises a heating chamber and a baking chamber, wherein an upper ventilating duct and a lower ventilating duct are correspondingly arranged at the upper end and the lower end of a wall between the heating chamber and the baking chamber; the heating chamber is communicated with the baking chamber through the upper ventilating duct and the lower ventilating duct; a heating furnace is arranged inside the heating chamber; a fan is arranged at the upper part of the heating furnace; the fan is connected with the upper ventilating duct through a fan air outlet; a cold air door for controlling air flow to enter is arranged on the side wall of the heating chamber; a dehumidifying channel with a ventilation opening is arranged at the bottom of the baking chamber; a row of dehumidifying windows are arranged at the tail end of an external dehumidifying channel of the baking chamber; and the humidifying system is characterized by also comprising an automatically-controlled humidifying system and an automatically-controlled dehumidifying system. The humidifying system of the bulk curing barn can meet precise requirements of humidity by a tobacco baking process, is good in baking effect and convenient to operate.

Description

technical field [0001] The invention relates to a humidity control system, in particular to a humidity control system for dense barns. Background technique [0002] With the advancement of science and technology and the development of modern agricultural construction, flue-cured tobacco production has entered the era of "modernization, scale, and intensification". A new generation of baking equipment - dense precision flue-cured tobacco curing room has been developed in tobacco leaf curing, replacing the The old-fashioned curing barn solves the problem of poor curing effect in the production of flue-cured tobacco. At present, this kind of intensive precision baking room has been researched and promoted in production. [0003] In the process of curing tobacco, the humidity in the curing room is one of the important factors affecting the effect of tobacco curing. However, there is no special humidity control system in the existing tobacco curing room. When the humidity in the...

AI Technical Summary

Problems solved by technology

[0003] In the process of curing tobacco, the humidity in the curing room is one of the important factors affecting the effect of tobacco curing. However, there is no special humidity control system in the existing tobacco curing room. When the humidity in the curing room When the humidity required by the baking process cannot be met, the existing baking equipment cannot make timely adjustments to the humidity in the baking room

[0004] During the tobacco curing process, when the temperature in the curing room reaches a certain temperature range, the humidity has an important impact on the curing process. If the humidity in the curing room is too low, it will seriously affect the quality of tobacco curing.

[0005] In addition, the humidity in the baking room should not be too high. Excessive humidity will prolong the drying time of tobacco leaves and affect the baking effect of tobacco leaves.

[0006] In short, if the humidity in the curing room is too high or too low, it will seriously affect the baking quality of the tobacco leaves. Accurate control has become an urgent problem to be solved
