Abstract

The present disclosure has provided an automatic multichannel apparatus for assessing hot coal fallout propensity of burning cigarettes and an assessing method thereof. The apparatus comprises a multichannel rotary plate unit, an automatic supplying unit for cigarette samples, an automatic ignition and burning line detection unit for cigarette samples, a cigarette holding and force applying unit, an automatic hot coal fallout detection and removal unit, a smoke collecting unit during suction, a suction unit, a gas exhaust unit arranged in a main frame, and an electric circuit and air path control unit for controlling actions and processes of the above units. The apparatus operates based on certain steps and performs automatic ignition and burning line detection on cigarette samples inserted into a rotary plate in sequence. A controllable external force is applied to the cigarettes during burning and suction, and hot coal fallout propensity of this kind of cigarette is detected by hot coal fallout occurrence of multiple cigarettes. The apparatus according to the present disclosure can improve test repeatability and working efficiency.
