Description

Technical Field

[0001] The invention belongs to the technical field of tobacco curing rooms, and in particular relates to a heat dispersion type tobacco curing room. Background Art

[0002] The flue-cured tobacco room is an indispensable basic equipment in flue-cured tobacco production. After the tobacco leaves are cured and tempered, they show the unique color, aroma, taste and shape of flue-cured tobacco, becoming high-quality raw materials that meet the needs of the cigarette industry. The basic principle is that after the tobacco leaves are heated, the moisture in the tobacco leaves is discharged, and the moisture is discharged outside the flue-cured tobacco room after vaporization, so that the tobacco leaves are roasted yellow and dry.

[0003] Intensive flue-cured tobacco rooms generally include a tobacco loading room, a hot air room, heating system equipment, ventilation and dehumidification, and hot air circulation system equipment. Its basic characteristics are that the tobacco loading density is relatively high, and fans are used for forced ventilation and hot air circulation. According to the direction of airflow, there are two types: airflow rising type and airflow descending type. The heating system equipment generally uses a coal-fired boiler or burner to send coal or biomass fuel into the furnace or the burner, and uses a fan to blow the hot air in the hot air room into the tobacco loading room to bake the tobacco leaves. Whether it is an airflow rising type or an airflow descending type flue-cured tobacco room, tobacco leaves are dried by circulating air. However, the wind direction of the circulating air is basically controlled by the wind force of the fan, which can easily cause the hot air temperature near the hot air room to be higher, while the hot air temperature far away from the hot air room is lower, resulting in uneven temperature in the tobacco loading room, affecting the baking quality of tobacco leaves; and the wind force near the hot air room is relatively large, which can easily cause tobacco leaves to be blown off during the color setting and dry tendon stages of tobacco leaves; in addition, when traditional coal-fired boilers or burners are heated, heat loss is large, and a large amount of dust and greenhouse gases are generated when fuel is burned, causing environmental pollution. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and to provide a thermally dispersed tobacco curing room, in which the traditional hot air chamber is eliminated and a plurality of groups of carbon crystal plates are arranged at the bottom and the top of the curing room body, which are transmitted to the outside in the form of heat radiation and weak convection. The heat radiation is mainly carried out in the form of far-infrared radiation. After the far-infrared radiation is absorbed by the tobacco leaves, it causes intense molecular resonance of the water inside the tobacco leaves. The molecular resonance generates heat, which causes the temperature inside the tobacco leaves to rise, thereby achieving the purpose of synchronous drying of the water inside the tobacco leaves and the water on the surface of the tobacco leaves, which not only improves the efficiency and quality of tobacco leaf baking, but also avoids environmental pollution.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

The carbon crystal plate transmits heat to the outside in the form of heat radiation and weak convection. The heat radiation is mainly carried out in the form of far-infrared radiation. After the far-infrared radiation is absorbed by the tobacco leaves, it causes intense molecular resonance of the water inside the tobacco leaves. The molecular resonance generates heat, which causes the temperature inside the tobacco leaves to rise, so as to achieve the purpose of synchronous drying of the internal moisture and surface moisture of the tobacco leaves, which not only improves the efficiency and quality of tobacco leaf baking, but also avoids environmental pollution. The moisture generated during tobacco baking is discharged through the dehumidification fan. When dehumidifying, open the cold air door, and the external air enters the flue-curing room body through the cold air door to promote the hot air circulation inside the flue-curing room body.

The blowing direction of the circulating fans is parallel to the bottom of the baking room body. The hot air at the top of the baking room body enters into the guide air duct and is blown out horizontally under the action of the circulating fans, so that a breeze circulation is formed inside the baking room body, thereby ensuring the hot air circulation inside the baking room body.

[0015] As a further optimization of the technical solution, a plurality of convection fans are provided on the upper part of one end of the first tobacco hanging rack, and the convection fans blow the hot air to one side of the guide duct, thereby enhancing the effect of hot air circulation and improving the efficiency of tobacco leaf baking.
