Problems solved by technology
[0007] However, although ordinary agricultural product dryers can shorten the drying time of agricultural products that are not sensitive to temperature and humidity, dry tobacco requires various drying environments depending on the type and harvested part. If the temperature and humidity are not adjusted properly, dry tobacco will rot. , and the drying operation cannot be carried out smoothly
[0008] In addition, the usual agricultural product dryer is a recovery device for recovering exhaust air heat, which has a complicated structure and always recovers the heat of the exhaust air passing through the exhaust outlet, so it is difficult to adjust the temperature and humidity.

An exhaust air heat recovery system of a tobacco leaf agricultural product dryer, according to the present invention, is characterized by a heat exchange means comprising: a recovery duct (330) which is arranged so as to communicate with one side of an exhaust air outlet (140); a damper (310) which is arranged so as to be rotatable between the recovery duct (330) and the exhaust air outlet (140), and which selectively opens and closes the recovery duct (330) and the exhaust air outlet (140) according to the forward or reverse rotation of a motor (320); an exhaust air heat exchanger (220) which is disposed inside the recovery duct (330) so as to recover the heat of exhaust air, which is expelled through the exhaust air outlet (140), and in which a heat transfer medium is circulated; an inlet heat exchanger (210) which is connected to the exhaust air heat exchanger (220) by a pipeline, and which heats air being sucked into an inlet (130) through the heat transfer medium which is circulated by a pump (250); and a control unit (450) which receives the measurement values of a temperature sensor (410) and a moisture sensor (420) which measure the temperature and the moisture of a drying room (120), and which outputs a control signal for controlling the operation of the tobacco leaf agricultural product dryer, wherein the exhaust air outlet (140) has therein an exhaust fan (510) for sucking in and blowing the air inside the drying room (120) during the drive of a driving motor (520) which drives according to the control signal of the control unit (450).
Description
technical field [0001] The present invention relates to an exhaust air heat recovery device of a dry tobacco agricultural product dryer, in particular, relates to a device for selectively recovering the exhaust air heat of the dry tobacco dryer used when drying tobacco crops such as dry tobacco according to the rotation direction of the damper, thereby , not only saves energy, but also can easily adjust the temperature and humidity suitable for drying. The exhaust heat recovery device of the dry tobacco agricultural product dryer with improved structure. Background technique [0002] Generally, an agricultural dryer that supplies high-temperature hot air to various agricultural products such as peppers, grains, and beans to dry agricultural products includes a drying furnace that provides a storage space for agricultural products and supplies hot air generated by electric heating or combustion to the The air heater of the drying furnace is provided with an air inlet and an e...
