Airflow alternating type and horizontal type intensive tobacco baking house

The utility model belongs to the technical field of tobacco baking equipment, and discloses an airflow alternating type and horizontal type intensive tobacco baking house. The airflow alternating type and horizontal type intensive tobacco baking house solves the problems that due to the fact that the upper-lower temperature difference and low-temperature dead corners exist in an existing tobacco baking house, the baking time is long and the baking cost is high. The airflow alternating type and horizontal type intensive tobacco baking house comprises a house body, wherein the house body comprises a front end wall, a rear end wall, side walls, a roof and a partition wall, a tobacco baking room is formed between the partition wall and the rear end wall, and a hot wind room and a heating room are arranged between the front end wall and the partition wall; an airflow upper channel opening and an airflow lower channel opening are formed in the partition wall; a heat supply device is arranged inside the heating room, a bi-direction circulating fan is arranged inside the hot wind room, and the bi-direction circulating fan is electrically connected with a variable frequency controller; the front end wall is provided with an airflow rising type cold wind inlet door, and the heating room is provided with an airflow falling type cold wind inlet door; the rear end wall is provided with an airflow rising type moisture removal window and an airflow falling type moisture removal window. The circulating fan is used for forcedly converting the direction of airflow, the upper-lower temperature difference and the dead corners inside the baking room are reduced, and the baking reject rate and the baking cost of tobacco are reduced.
