Granular flow dynamics present unique storage challenges. Whether handling hygroscopic engineering plastics, organic animal feed, or premium coffee beans, the interstitial air between particles is a catalyst for chemical degradation. Traditional woven sacks fail to address this fundamental flaw. This engineering analysis explores the mechanics of using a granular vacuum packaging machine to extract ambient air. We investigate how achieving a negative pressure environment is the only scientifically sound method to prevent material caking, ensuring absolute granular material preservation while simultaneously optimizing bulk material logistics for global supply chains.
