Tobacco air-curing shed

Abstract

The invention relates to a tobacco air-curing shed. The ground of a shed body is provided with an underground air passage; a plurality of air supply openings are formed in positions, positioned under tobacco air-curing frames, of the underground air passage; an air outlet of a blast blower is connected with the underground air passage through an air supply pipe; and an air inlet of the blast blower is connected with an air inlet pipe. The tobacco air-curing shed is also provided with a circulation air pipe; the circulation air pipe is connected with an air inlet of the blast blower; and an inlet of the circulation air pipe is positioned in a position near the top of the shed body. The tobacco air-curing shed provided by the invention has the advantages that by using a lower air supply structure, the air is uniformly distributed to tobacco air-curing units of each tobacco air-curing frame; the hot air has the naturally ascending trend, so that the whole circulation air flow distribution is uniform; and the energy consumption is low. The circulation air pipe and the air inlet pipe connected with the blast blower are switched through a first valve and a second valve; the switching between fresh air introduction and internal circulation is realized; and the temperature and the humidity in the tobacco air-curing shed can be conveniently regulated. An installed hot-air fan and an installed dehumidifier are matched with a temperature sensor and a humidity sensor, so that the temperature and the humidity in the tobacco air-curing shed can be further precisely regulated.

Description

Technical field

[0001] The present invention involves the field of tobacco leaves to make cigarette sheds. Background technique

[0002] The existing dry smoke (white ribs, Maryland smoke) tobacco leaves are dry in the shed, which is an important part of my country's tobacco leaf products.When the existing technology is made of tobacco leaves, it is mainly completed under natural mild humidity. In this case, because the humidity and temperature are not controlled, the tobacco leaves are easy to deteriorate.

[0003] China Patent CN101831992B has disclosed a cigarette house in the heat air flow. By setting the mezzanine in the shed, the heating airflow cycle is achieved.Heating and dehumidification need to introduce fresh air. Invention content

[0004] The technical problem to be solved by the present invention is to provide a kind of cigarette shed, which can realize the automatic control of temperature and humidity in the cigarette shed, and the structure is simple, easy to ...
