Thermal distributed tobacco curing barn

Abstract

The invention discloses a thermal distributed tobacco curing barn. A plurality of groups of carbon crystal plates are arranged at the bottom and the top of a curing barn body; the upper side of the back surface of the curing barn body is provided with a number of dehumidifying fans, and a cold air door is arranged on the lower side of the back surface of the curing barn body; a first tobacco hanging frame is arranged in the middle of the curing barn body, a second tobacco hanging frame is arranged on the inner walls of the two sides of the curing barn body, and a temperature sensor, a humiditysensor and the carbon crystal plates are electrically connected with a control cabinet through wires. According to the invention, a traditional hot air chamber is cancelled; the plurality of groups of carbon crystal plates are arranged at the bottom and the top of the curing barn body; heat radiation and weak convection are transmitted to the outside; heat radiation is mainly carried out throughfar infrared radiation, after the far infrared radiation is absorbed by tobacco leaves, intense molecular resonance of moisture in the tobacco leaves is caused, the molecular resonance generates heat,the temperature in the tobacco leaves is promoted to rise, the purpose of synchronously drying the moisture in the tobacco leaves and surface moisture is achieved, the tobacco leaf baking efficiencyand quality are improved, and environmental pollution is avoided.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco rooms, in particular to a heat-distributed tobacco flue-cured room. Background technique [0002] The flue-cured tobacco room is an indispensable basic equipment in the production of flue-cured tobacco. After the tobacco leaves are internally cured, they will show the unique color, aroma, taste and shape of flue-cured tobacco, and become high-quality raw materials that meet the needs of the cigarette industry. The basic principle is that after the tobacco leaves are heated, the water in the tobacco leaves is discharged, and the water is vaporized and then discharged out of the flue-curing room, so that the tobacco leaves are yellowed and dried. [0003] Intensive flue-cured tobacco rooms generally include a tobacco chamber, a hot air chamber, heating system equipment, ventilation and humidity removal, and hot air circulation system equipment. There are air-flow ascending type and air-...

AI Technical Summary

Problems solved by technology

Regardless of the ascending airflow or descending airflow flue-curing room, the 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 will easily cause the temperature of the hot air near the hot air chamber to be higher, and the temperature of the hot air far away from the hot air chamber. low, resulting in uneven temperature in the tobacco-loading room, which affects the baking quality of the tobacco leaves; and the wind force close to the hot air chamber is relatively strong, which may easily cause the tobacco leaves to be blown during the stage of tobacco leaf color fixing and rib drying; in addition, traditional coal-fired boilers or combustion When the machine is heated, the heat loss is large, and a large amount of dust and greenhouse gases are generated when the fuel is burned, causing environmental pollution
