포장용 링타입 고무막 One-way 밸브의 가스배출압력 예측을 위한 수학적 분석 모델 = Analytical Model for Predicting Degassing Pressure of the One Way Valve with Ring Type Rubber Disk for Packaging

다국어 초록 (Multilingual Abstract)

One-way degassing valves usually designed for coffee packaging are recently applied to the various food packaging such as fermented health functional food or home meal replacement (HMR) packaging. The optimized degassing pressure by food product is important factor for keeping effective freshness and improving preservation of the food, therefore the development of degassing valves specified with various open pressure is needed. In this study, the mechanical characteristics of the degassing valve with ring type rubber disk were analyzed and a mathematical model was developed to predict the open pressure of the valve. The model was verified with test results derived from several available valves, and it may be useful in designing and developing a new valve.
