The invention provides a hot air temperature control method for a drum type machine used in tobacco processing technology. The characteristic of this method is to change the original heat exchanger as datum quantity by steam injection quantity control means, instead of using a constant steam injection quantity for reference quantity, by adjusting the steam heat exchanger to the stability of air temperature control. Compared with the previous control method, the invention of steam injection with constant flow form quantitative join, realize the quantitative control of steam injection, reduce the water change because the steam is caused by the fluctuation of air temperature at the same time, to overcome the thermal inertia of heat exchanger caused by the presence of the regulation of the fluctuation. The method makes the process of cigarette processing more refined and improves the quality of cut tobacco.

用于烟片加工的滚筒类设备热风温度控制方法,其特点在于,改变热风控制模式,以蒸汽喷射的定量控制为基准量,通过对热交换器蒸汽调节阀的控制,恒定量化进入滚筒设备中的蒸汽流量,实现热风温度的控制;具体如下:首先根据烟片物料的流量调整蒸汽喷射控制薄膜阀的开度,固定其开度,使喷入滚筒内的蒸汽量恒定并使其所提供的热量小于烟片物料升温所需的热量5-10%;同时通过启停通入热交换器内部的蒸汽阀微调热风温度,即热风温度达到设定值时停止热交换器蒸汽的供给,低于设定值时打开进蒸汽阀,实现热风温度的平稳变化。
