The invention provides a control method, a control device and cigarette processing equipment. The control method comprises the following steps: acquiring an actual temperature value of air in a circulating air pipe and an expected temperature set value of an internal environment of a roller in the tobacco processing process; calculating a first difference value between the temperature set value and the actual temperature value, comparing the first difference value with a first lower limit value and a first upper limit value, and calculating an adjusting temperature value according to the comparison result; and calculating a second difference value between the adjusting temperature value and the actual temperature value, comparing the second difference value with a second lower limit valueand a second upper limit value, and adjusting the opening degree of a valve positioner according to a comparison result. The stability of roller hot air temperature control can be improved.
