Zhang Guowang, Secretary of the municipal Party committee, led a team to visit Jialong tech for investigation and guidance

On Dec.24, Jialong's production team has finished the production of fully-auto vacuum packing machine , carton loading machine and robotic palletizing line . All the goods are loaded into 7 containers. This packing line will be the most advanced one in the rice packing industry in Thailand

Director of Zhangzhou Municipal People's Congress visits Jialong Technology.

Vacuum packaging for granular materials is often promoted as a shelf-life tool, but the engineering value is wider. A correct vacuum packing system can reduce oxygen exposure, limit moisture ingress, protect aroma, improve tamper evidence, and increase pallet density. This technical note explains how buyers should evaluate film barrier, vacuum recipe, package compaction, seal integrity, and handling damage before approving a granule packaging line.

Vacuum packaging cannot repair a cracked walnut or restore a broken cashew. The real engineering task is to protect whole-kernel value after grading. A nuts packing machine should reduce drop impact, control weighing vibration, prevent hard vacuum compression, and hold seal quality without crushing brittle kernels. This technical note explains how feeding, weighing, nitrogen cushioning, pouch firmness, and carton handling protect premium nut appearance.

Vacuum-packed rice is moving from simple oxygen removal toward controlled package design. Premium rice needs aroma protection, stable grain texture, easier handling, food-contact material review, and traceability that survives the final pack shape. This technical note explains how vacuum recipes, nitrogen flushing, zipper-ready bags, recyclable material claims, and QR-based packaging data should be tested before a rice vacuum packing machine is approved for production.

Granular materials do not respond to vacuum packaging in one uniform way. Coffee beans, nuts, grains, seeds, sugar, spices, and chemical granules have different risks: aroma loss, moisture absorption, caking, oxidation, puncture damage, and particle breakage. This technical note explains how vacuum level, barrier film, seal temperature, dust control, and storage environment should be tuned before a granule packing machine is approved for production.

The future of vacuum-packed nuts is less about novelty and more about measurable control. Nuts need protection against oxygen, moisture, light, oil migration, and mechanical breakage. This technical note reviews three practical directions for 2026 equipment planning: stronger barrier validation, controlled vacuum and nitrogen recipes, and QR-ready packaging that can carry traceability data without damaging seal quality or line speed.

Vacuum-packed rice fails when the package loses its barrier or traps unstable moisture inside the bag. Pinholes, seal splits, carton compression, and temperature cycling can destroy the vacuum effect even when the machine appears to run normally. This technical note explains how composite film choice, sealing jaw control, vacuum decay testing, rice moisture verification, and warehouse temperature discipline should be treated as one engineering process.

Polished rice can lose commercial value before oxygen becomes the main problem. Excessive vacuum pressure pushes brittle grains into hard contact, while poor seal control turns a clean brick pack into a fractured, hard-to-open block. This technical brief explains how vacuum level, evacuation time, nitrogen backfill, film structure, and sealing jaw pressure should be tuned as one process rather than separate settings.
