A mechanized system for bagging fruits is crucial, especially in places where horticultural products are produced and harvested on large scales. In this regard, it is equally important to open the bag without damaging the fruit. The objective of this study was to design an automated device for opening of young apple fruit bags and to analyze its mechanical structure and working principle. This was accomplished by examining factors influencing the bag-opening amplitude and determining key parameters of the device used for bag-opening on paper bags. A single-factor test was conducted to examine how each factor influences the size of the bag-opening amplitude. The optimal combination of parameters was determined by employing orthogonal testing, analysis of variance, response surface analysis, and multi-objective optimization. The observations indicated that the optimal combination consisted of a blowing angle of 6.4°, blowing air pressure of 13.0 kPa, and blowing height of 82.85 mm. There was no damage to bag during the bag-opening test, and the bag-opening amplitude was averaged at 47.80 mm. The study findings showed that the bag-opening effect aligned with the expected outcomes for modern fruit bagging systems aimed at younger fruits.
