Heat-pump-type heat-recovery tobacco drying device controlled by computer

Abstract

The invention discloses a heat-pump-type heat-recovery tobacco drying device controlled by a computer. A horn opening in the left end of an air outlet hopper of a heat preservation enclosure is provided with baffle-controlled sine-wave humidness expansion devices, the distance between a baffle and the horn opening in the left end of the air outlet hopper is automatically controlled by the humidness, and an outlet in the right end of the air outlet hopper corresponds to a vapor-liquid-coexistence coil pipe area of an external machine; tobaccos are densely hung into the heat preservation enclosure, the temperature and the humidness of drying are automatically adjusted by the computer according to the temperature and the humidness, and the optimum drying effect is obtained. According to the heat-pump-type heat-recovery tobacco drying device controlled by the computer, as a temperature-fluctuation-generated sine-wave heat-expansion and cold-contraction device expands to automatically control the size of the air volume, even efficient drying can be achieved; as the sine-wave humidness expansion devices controls an air door through humidness to automatically control the humidness-discharging air flow, the drying rate can be specially increased; as a humidness discharging opening is aligned to the vapor-liquid-coexistence coil pipe area, efficient recovery of tail heat can be specially achieved, and energy saving and efficiency are achieved; efficient recovery of the tail heat of a system can be specially achieved through external-machine-fin-coil-pipe design, and meanwhile power consumption of a compressor is special low.

Description

technical field [0001] The invention relates to a heat pump type heat recovery tobacco leaf drying device controlled by a computer. Background technique [0002] Tobacco leaves, annual herb, Solanaceae, plant covered with glandular hairs, about 1 meter high, petiole is not obvious or wing-like stalk, feels sticky to the touch, panicles are terminal, calyx tube-shaped, corolla funnel-shaped, shaped like Trumpet, terminal pink, capsule, seed yellowish brown. Native to South America, it is cultivated all over the world. Tobacco leaves are the raw material for the tobacco industry. [0003] In order to facilitate the later processing, it is necessary to dry the fresh tobacco leaves. At this stage, there are mainly two kinds of artificial natural drying and dryer drying. Natural drying is greatly affected by the weather and has low efficiency, which is not conducive to the industrialization of tobacco leaves; while the existing drying machine can achieve rapid drying, but beca...

Problems solved by technology

Natural drying is greatly affected by the weather and has low efficiency, which is not conducive to the industrialization of tobacco leaves. Although the existing drying machine can achieve rapid drying, it also discharges a large amount of heat while dehumidifying, so the energy consumption is high. economically uneconomical
