Description

Technical Field

[0001] The utility model relates to the technical field of tobacco leaf baking equipment, in particular to a circulating air electric tobacco leaf baking house with high-efficiency dehumidification. Background Art

[0002] Tobacco leaf baking is an important step in tobacco leaf processing, and tobacco leaf baking equipment is required for tobacco leaf baking. Among them, the heating device is the core component of the baking equipment. The Chinese patent with the authorization announcement number CN218245606U discloses an electric heating type tobacco leaf baking house, which realizes the heating of the circulating air flow in the tobacco loading chamber by means of electric heating. However, in different stages of tobacco leaf baking, the baking temperature is different. In the prior art, the method of changing the heating temperature in the tobacco loading chamber is usually to change the power-on of the heating device. Only by changing the power-on of the heating device, since the area of the air passing through the heating device remains unchanged, it takes a long time for the temperature in the tobacco loading chamber to change to the required temperature, resulting in a long interval of temperature stabilization time between the two stages, increasing the overall duration of flue-cured tobacco; it may affect the quality of flue-cured tobacco.

[0046] In the above embodiments, since the internal circulation dehumidifier 5 is a conventional device in the equipment room 2 of the existing tobacco leaf curing barn, the present invention does not improve its specific internal structure, and therefore does not further describe its structure.

[0047] In the above embodiment, an internal circulation dehumidifier 5, a circulation fan 6 and a heating assembly 7 are sequentially arranged in the equipment room 2 from top to bottom, and the airflow is guided downward by the circulation fan 6 so that the airflow flows through the electric heating plate 72 of the heating assembly 7. After the airflow is heated, it enters the tobacco loading chamber 1 from the second sealed window below to dry the tobacco leaves hanging in the tobacco loading chamber 1. The moisture of the tobacco leaves carried by the airflow flows back to the upper part of the equipment room 2 from the first wind window 3 above, and the moisture carried by the airflow is removed by the internal circulation dehumidifier 5, thereby circulating; in the heating assembly 7, the electric heating plate 72 can move along the X direction with the movable frame 71, and the electric heating plate 72 can move along the X direction with the movable frame 71.

In the conventional structure of a tobacco leaf baking house, a moisture exhaust window is provided on one side of the tobacco loading chamber 1. At this time, the moisture exhaust window is opened to conduct an external air circulation to assist in moisture exhaust.
