Summary Microporous film and MAP were evaluated to find the optimal method for extending postharvest storage of strawberry. To determine most suitable system strawberry, fruits stored in controlled atmospheres (O 2 /CO partial pressures kPa: 5/10; 10/10; 5/15), a separate experiment, strawberries sealed container with different microporous PET/PE films. Results showed that optimum atmosphere was 10 kPa O + CO which could be achieved maintained by using four perforations 100 μm. By...

Abstract The coefficient of restitution (COR) is used to estimate the equivalent free fall drop height packaging during handling and transportation. Various experimental studies were designed explore factors affecting conversion COR height. These include number drops, height, orientation, base, temperature humidity on COR. results indicate that drops orientation are two most influential values. As package undergoes more increases. Among various orientations, largest for flat followed by edge...

In this study, a centrifugal feeding disc device is proposed. To investigate the influence of process parameters on discharging efficiency and lifting efficiency, was dynamically simulated based discrete element method (DEM), simulation results were experimentally verified. Based quadratic regression orthogonal test method, significant lossless model established, response surface interaction obtained. The indicated that order speed as follows: outer turntable > inner tilt angle conical...

A backpressure filling system is a kind of air type which could be applied to power type, fine or coarse grain, mixtures with and components. The working principle was discussed based on fundamental hydromechanics. research limit values were achieved via mechanical analysis. Comparing the exit velocity material by theoretical analysis numerical simulation, CFD simulation model confirmed its related parameters determined. shows relationship between production capacity packaging machine...

Both analyses of the damage boundary and shock response spectrum (RSR) are basis for development protective packaging system. The analysis through lab test numerical simulation found that root cause failure was due to stress critical component beyond yield limit material. Lab data showed design based on is conservative, RSR could be helpful provide support develop more effective Furthermore, can accurately analyze entire product system in great detail.
