Description

Promote bulk curing barn and intelligent wind distribution device and bulk curing barn of dehumidification efficiency

Technical Field

The utility model belongs to the technical field of tobacco leaf processing, concretely relates to promote intelligence wind-dividing device and bulk curing barn of bulk curing barn hydrofuge efficiency.

Background

The bulk curing barn has been widely accepted since the mass popularization of the bulk curing barn in tobacco areas in China, and the airflow descending type curing barn is most popularized and applied at present along with the development of a new energy curing barn. The airflow descending type curing barn main body consists of a heating chamber and a tobacco containing chamber, the two chambers are in airflow circulation communication through a hot air return port at the bottom end of a heat insulation wall and a hot air inlet at the top end of the heat insulation wall, and the whole circulation process is forced to circulate by a fan.

The bulk curing barn heating is that external low-temperature air is sucked through a cold air inlet and enters a curing barn heating chamber, after the cold air is heated by a heating furnace in a heating chamber, hot air flow is pressed into a tobacco loading chamber through a hot air inlet by a circulating fan, the hot air flows through a tobacco layer after being uniformly dispersed, tobacco leaves are heated, the change of the tobacco leaves is promoted, and surplus air flow enters the heating chamber through a hot air return opening of the curing barn to circularly supply heat to the curing barn for heating and heat preservation; the humidity elimination of the curing barn is realized by sucking outside air with lower humidity through a cold air inlet to form pressure difference under the action of a circulating fan and then eliminating the air with higher humidity in the tobacco loading chamber through a humidity elimination air port, so that the humidity elimination capability of the curing barn depends on the amount of dry and cold air sucked from the outside in unit time and the pressure difference in the curing barn to a great extent.

However, in the existing bulk curing barn, as shown in fig. 1, the moisture exhausting air inlets 2 are located on both sides of the hot air return air inlet 1 of the curing barn, and tobacco leaves are dehumidified while the curing barn is heated and heated, and in the actual production process, because the area of the hot air return air inlet is larger than that of the moisture exhausting air inlet, and air dividing devices are not arranged at the air return air inlet and the moisture exhausting air inlet, most of air flow circulates through the hot air return air inlet, and less of air flow participates in the moisture exhausting, so that the moisture exhausting of the curing barn is not smooth, a large amount of bad tobacco leaves are generated, the quality of tobacco leaf curing is greatly influenced, and the income of tobacco growers is reduced.
