The moisture drying control device of the cut-tobacco drier as claimed in claim 5, wherein: an air inlet thermometer (201) and an air inlet hygrometer (202) are respectively arranged at one end, close to the roller cut-tobacco drier (1), of the hot air pipeline (20), and an air outlet thermometer (402) and an air outlet hygrometer (403) are respectively arranged on the moisture exhaust pipeline (40).
7. The moisture drying control device of the cut-tobacco drier as claimed in claim 6, wherein: a feeding water content tester (5) for detecting the water content of the cut tobacco to be dried is arranged above a feeding belt of the roller cut tobacco dryer (1); and a discharged water content tester (6) for detecting the water content of the dried cut tobacco is arranged above a discharged belt of the roller cut tobacco dryer (1).
8. A method for controlling the moisture drying of a cut-tobacco drier is characterized in that the moisture drying control device of the cut-tobacco drier according to any one of claims 1 to 7 is adopted, and the method comprises the following steps:
s1, after the hot air blower (2) and the steam injection equipment (3) are started, the hot air valve (200) and the steam injection valve (300) are opened, dry hot air generated by the hot air blower (2) and water vapor generated by the steam injection equipment (3) are conveyed into the roller cut tobacco dryer (1) through the hot air pipeline (20), and the temperature and the humidity of wet hot air in the hot air pipeline (20) are adjusted by changing the air outlet temperature of the hot air blower (2) and the opening degrees of the hot air valve (200) and the steam injection valve (300);
s2, after the exhaust fan (401) is started, the moisture exhaust valve (400) is opened, the damp and hot tail gas after the cut tobacco is dried in the roller cut tobacco dryer (1) is conveyed into the filter element (44) of the dust removal device (4) through the moisture exhaust pipeline (40), and the exhaust speed of the damp and hot tail gas in the moisture exhaust pipeline (40) is adjusted by changing the opening degree of the moisture exhaust valve (400);
s3, opening a circulating valve (410), conveying the wet and hot tail gas subjected to dust removal by a filter element (44) into a hot air pipeline (20) through a circulating pipeline (41), heating and diluting fresh wet and hot air in the hot air pipeline (20) and blowing the wet and hot tail gas subjected to dust removal into the roller cut-tobacco drier (1) again, and adjusting the circulating return amount of the wet and hot tail gas subjected to dust removal by changing the opening degree of the circulating valve (410); when the circulation returning of too much damp and hot tail gas is not needed, the pressure relief valve (420) is opened, and the circulation returning amount of the damp and hot tail gas after dust removal is adjusted by changing the opening degree of the pressure relief valve (420);
s4, periodically opening the slag discharge valve (450), and discharging the dust at the bottom of the filter element (44) into the dust collection groove (47) through the slag discharge pipe (45).
