Description

Technical Field

[0001] The utility model relates to the technical field of tobacco manufacturing, and particularly relates to a heat energy circulation device for a tobacco baking room. Background Technique

[0002] Tobacco is a plant of the genus Nicotiana in the Solanaceae family, an annual or limited perennial herb, all covered with glandular hairs, with thick roots, a stem height of 0.7 - 2 meters, and the base is slightly lignified. The leaves are oblong-lanceolate, lanceolate, oblong or ovate, with the apex gradually tapering and the base gradually narrowing to form auricles around the stem and semi-clasping the stem. The inflorescence is terminal, conical, multi-flowered, and the pedicel is 5 - 20 mm long. The capsule is ovoid or oblong-ovoid, about equal in length to the persistent calyx. The seeds are round or broadly oblong, about 0.5 mm in diameter, and the color is brown.

[0003] Tobacco baking is divided into five stages, which are respectively divided into the yellowing stage of the bottom-layer tobacco leaves, the main temperature in this stage is 36 °C to ensure the yellowing of the bottom layer; the yellowing stage of the middle and upper-layer tobacco leaves, the task in this stage is to ensure that the tobacco leaves turn yellow sufficiently, with the second-layer tobacco leaves yellow and the veins green; the temperature rises from 42 °C to 48 - 49 °C, and this stage is to complete the transition from yellowing to drying of the tobacco leaves; that is, the dry leaf stage, which means the temperature rises from 48 °C to 54 °C, and at the end of this stage, it is required that all tobacco leaves are yellow flakes, yellow veins, large rolls, and the leaves are completely dry; that is, the dry vein stage, which means the temperature rises from 54 °C to 68 °C until it stops. During the process of tobacco drying, it is necessary to continuously heat the baking room to keep the temperature of the tobacco at a constant and appropriate level at each stage, and the water vapor generated by the moisture inside the tobacco is discharged through the dehumidification pipe.

[0004] In the prior art, hot air drying is mostly used for tobacco baking. However, since the tobacco contains moisture, during the baking process, water vapor is discharged through the dehumidification pipe, and it is very difficult to achieve heat energy circulation as the hot air escapes.

By means of water heating, a coiled pipe is used to circulate high-temperature water in the baking room, thereby achieving the effect of increasing the internal temperature of the baking room. By cooperating with the flowing cycle of water, heat energy is recovered, and after reheating, the water in the coiled pipe is always in a high-temperature state. While not affecting the dehumidification effect, the heat in the baking room is maintained, and heat loss caused by hot air escape is reduced. Content of the Utility Model
