Abstract: To improve the efficiency and avoid operator errors, an automatic test cigarette sample preparing system was designed, which was mainly composed of test sample forming & printing unit, automatic sealing & filling unit, and software control & analysis system. Cigarette samples were selected by hopper and ink-jet printed in test sample forming & printing unit, then were assembled and sealed in automatic sealing & filling unit. Software control & analysis system conducted sample encoding scheme generation, sample preparing process control, and statistical analysis of evaluation results. The results of application showed that the designed system realized the automation of test sample preparation and result judgment. The time needed for a triangular test of 20 groups of cigarette samples by a panel of 25 members decreased from 1260 to 198 minutes, the accuracy and reliability of cigarette sensory evaluation were improved.
