Flour is highly hygroscopic and susceptible to lipid oxidation and pest infestation. Traditional paper packaging fails to mitigate these biological and chemical threats. This engineering report explores how utilizing a highly calibrated flour vacuum packaging machine halts these degradations. We analyze the critical role of vacuum sealing technology combined with advanced moisture barrier film in securing the micro-environment to effectively prevent flour oxidation in large-scale industrial flour packing operations.

Milled wheat is chemically unstable. From the moment of processing, lipids within the germ begin to oxidize, and hygroscopic properties invite moisture. Traditional woven sacks fail to address these fundamental decay mechanisms. This engineering analysis explores the transition to vacuum brick packaging for high-value flours. We examine the technical challenges of handling micron-level particulates, the necessity of specialized filtration systems in vacuum pumps, and how the Jialong system extends shelf life by 50% while stabilizing the logistics chain.
