Creating a perfect "Rice Brick" requires more than air removal. This technical report analyzes the sophisticated two-step process employed by a modern rice vacuum packaging machine. We explore the engineering principles of "Secondary Vacuuming" within a rigid mold constraints, a defining feature of the vacuum shaping machine. Unlike standard equipment, a brick shape packaging machine forces granule rearrangement to maximize density. As a precision packaging machine manufacturer, we detail how our automatic vacuum packing machine executes this complex cycle to achieve superior structural integrity.

Different legumes require distinct packaging parameters to maintain integrity. This technical report analyzes how a modern vacuum shaping machine adjusts to grain morphology. We examine specific data points: maintaining 0.08MPa for round grains versus 0.06MPa for oval grains to prevent bag rupture. We also explore the integration of nano-coated films in food packaging equipment to reduce OTR to 1.2cc. As a specialized packaging machine manufacturer, we detail how our automatic vacuum packing machine provides the precise control needed for a superior legume packaging machine.
