In industrial grain processing, equipment reliability is paramount. This technical bulletin outlines the official maintenance protocols for the Jialong rice vacuum packaging machine. From critical vacuum pump oil checks to sealing jaw integrity inspections, adhering to this preventive maintenance schedule is essential for operational continuity. This guide provides facility managers with a structured approach to preserving industrial packaging equipment assets.

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.

Traditional packaging bottlenecks result from linear processing. This technical report analyzes how the modern granular vacuum packaging machine overcomes this through multi-station topology. We explore the engineering behind the automatic shaping packing machine, which separates weighing from vacuum sealing to achieve parallel operations. As a packaging machine manufacturer, we examine the integration of pneumatic shaping mechanics within a rice vacuum packaging machine. We also detail the precision control of the weighing and bagging machine unit.

The transition from loose bags to six-sided "rice bricks" represents a significant engineering leap. This analysis explores how a modern rice vacuum packaging machine achieves an oxygen permeability rate of <5cc/m²·24h. We examine the dual-chamber mechanics of the brick shape packaging machine and how it shapes PA composite films into rigid structures. As a packaging machine manufacturer, we detail the precision required in an automatic vacuum packing machine to increase output by 66.7% while ensuring long-term seal integrity within industrial food packaging equipment lines.

On December 12, 2025, Jialong Technology participated in the 24th Jingchu Grain & Oil Boutique Exhibition in Wuhan. As a specialized packaging machine factory, we demonstrated our latest rice vacuum packaging machine, the LZB-1200-R40/S. This report analyzes how our automatic packaging systems integrate data analytics to optimize the grain industry. We explore the technical advancements in food packaging machinery that drew industry experts to our booth, affirming our leadership in grain packing machine innovation.

The modern rice vacuum packaging machine is a sophisticated instrument born from a century of innovation. This technical analysis traces its evolution from rudimentary vacuum chambers to the intelligent automatic packaging systems of today. We examine key engineering milestones, from advancements in vacuum pump technology to the integration of microprocessors. As a long-standing packaging machine factory, we detail how each developmental phase of the vacuum packaging machine and food vacuum sealer machine has systematically improved preservation science.

At the 7th Grain Conference in Shenyang (July 12-14), Jialong Technology launched its "All-in-One Smart Packaging Ecosystem" to showcase industry leadership. Its solutions impressed officials like Director Wang Jindong during a booth visit, earning high praise.
