Roasted coffee presents a unique engineering challenge: it requires oxygen exclusion while simultaneously releasing carbon dioxide. This technical report analyzes how a specialized coffee vacuum packaging machine balances these conflicting needs. We explore the integration of one-way degassing valves within an automatic vacuum packing machine and the mechanics of brick-shaping for dense storage. As a specialized packaging machine manufacturer, we examine the seal integrity required for food packaging equipment handling multi-layer foil laminates typical in the coffee bean packaging machine sector.

The trend towards "block-shaped" or brick-format legumes demands precise engineering. This technical analysis explores how a specialized vacuum packaging machine utilizes multi-axis compression to achieve this dense geometry. We examine the role of the brick shape packaging machine in extending shelf life to 12 months by minimizing interstitial oxygen. Furthermore, we discuss the integration of this technology into a modern bean packaging machine line and the role of food packaging equipment in ensuring seal integrity within an automatic vacuum packing machine system.
