1. IntroductionVacuum drying is an advanced drying technology that removes moisture or solvents from materials by combining reduced pressure, controlled heating, and vapor removal inside a sealed drying system.Unlike conventional hot air drying, which relies mainly on high-temperature air circulatio
—Why Does It Determine Powder Flowability and Mixing Difficulty?In powder engineering, many parameters are used to evaluate powder behavior, including:Particle size;Particle size distribution;Angle of repose;Bulk density;Tapped density;Flowability;Cohesion.However, one of the most fundamental proper
