Description

Technical Field

[0001] The utility model relates to the field of tobacco leaf baking equipment and seedling raising equipment, in particular to a flue-cured tobacco temperature-increasing and energy-saving seedling raising facility. Background Art

[0002] In flue-cured tobacco growing areas, densely packed drying houses and seedling greenhouses are generally built separately, occupying more land resources. Moreover, both types of facilities are only used for 2-3 months each year, with long idle times, single functions and low utilization rates.

[0003] The tobacco seedling raising season in the southeastern tobacco planting area is from December to February of the following year. The temperature is low and the tobacco seedlings are often affected by low temperature and frost damage. The tobacco leaf baking season is from May to July every year. When the middle and lower parts are baked, there are many rainy seasons, with heavy rainfall and high air humidity. During the baking process, the baking room uses heat supply and inhalation of outside air for heat exchange and dehumidification, thereby drying the tobacco leaves. The air humidity is high in rainy weather, and the inhalation of high-humidity air causes a significant reduction in dehumidification efficiency. It is difficult to coordinate the water loss of tobacco leaves with yellowing, which affects the baking quality of tobacco leaves. However, the temperature in the closed seedling greenhouse is higher than that of the outside world and the air humidity is lower. When the middle and upper parts are baked, it is in a sunny and hot summer with little rainfall, high temperature and dryness. In sunny weather, the temperature in the closed seedling greenhouse can exceed 60°C, which just meets the heat needs of tobacco leaves in the early stage of baking and reduces baking energy consumption.

[0004] For example, a flue-cured tobacco seedling warming and energy-saving baking device with publication number CN219019731U has the function of realizing the comprehensive utilization of intensive curing rooms and seedling greenhouses, saving construction land, being beneficial to the cultivation of strong flue-cured tobacco seedlings in winter, avoiding adverse weather and saving energy and reducing consumption. The flue-cured tobacco seedling warming and energy-saving baking device utilizes the flow of hot air into the seedling greenhouse to increase the temperature, but the air flow speed is slow. The closer to the heating chamber, the higher the temperature is, and the hot air flow is less on the side away from the heating chamber, which affects the uniformity of the temperature inside the seedling greenhouse.

[0005] Therefore, it is necessary to provide a flue-cured tobacco warming and energy-saving seedling raising facility to solve the above technical problems. Utility Model Content

[0007] In order to solve the above technical problems, the utility model provides a flue-cured tobacco temperature-increasing and energy-saving seedling raising facility, comprising: a flue-curing room;
