Coffee is volatile. The moment it leaves the roaster, it begins to die. Oxygen attacks the delicate lipids, killing the crema and the flavor. This technical report analyzes the thermodynamics of coffee staling. We explore how the Jialong coffee vacuum packaging machine creates a "skin-tight" anaerobic environment. Learn why the vacuum brick for coffee is the only reliable coffee bean storage technology to prevent coffee oxidation and preserve coffee aroma for international export.

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.
