Cashew Vacuum Packing Machine
Nitrogen-flush, export shelf life
Vacuum and nitrogen-flush packing lines that seal graded kernels into tins or pouches for long, export-ready shelf life.
The TTQ Cashew Vacuum Packing Machine seals graded kernels under vacuum with a nitrogen flush, removing oxygen so cashews stay fresh, crisp and rancidity-free through long export shipping. It packs the industry-standard formats — 10 kg vacuum tins and blocks, and retail pouches — at 50–70 packs per hour on a 45-second vacuum cycle with two operators. Nitrogen flushing gives cashew kernels a shelf life of up to 12 months, which is what makes container-load export viable.

What holds twelve months of shelf life
Export-ready formats
Seals the standard 10 kg vacuum tins and blocks plus retail pouches from one line.
Nitrogen-flush freshness
Displacing oxygen with N₂ keeps kernels crisp and prevents rancidity in transit.
Up to 12-month shelf life
Long, stable shelf life is what makes full-container export shipping viable.
Semi or fully automatic
Scale from an operator-fed sealer to an automatic packing line as volume grows.

Vacuum packing is the stage that turns a perishable kernel into an exportable one. Cashews oxidise and go rancid in contact with air, so removing the oxygen — and replacing it with nitrogen — is what converts a few weeks of shelf life into up to twelve months. Everything else about the pack is secondary to that.
Formats
| Format | Use | Typical throughput |
|---|---|---|
| 10 kg tins and blocks | The export standard for bulk kernel | 50–70 packs per hour |
| 25 lb / 50 lb bags (11.34 / 22.68 kg) | Bulk trade, particularly to North America | 50–70 packs per hour |
| Retail pouches, 100–500 g | Consumer packs, usually on a separate pouch line | Weigher-dependent |
Double-chamber machines seal one side while the operator loads the other, which is where most of the throughput gain comes from on bulk formats.
How it works
Chamber evacuation
the pack is placed in a sealed chamber and air is drawn out to a set vacuum level.
Nitrogen flush
inert gas replaces the evacuated air, displacing residual oxygen and stopping the film pulling hard onto the kernels, which reduces breakage in transit.
Heat sealing
the seal bar closes the pack. Temperature and dwell time are set for the film in use, and both matter more than operators usually expect.
Cooling
the seal has to set before handling, or it fails later in the container rather than in your factory.
Programmable control
recipes per bag size and film type, so changing format does not mean re-learning the settings.
What determines whether the pack holds
Kernel moisture below 5%
packing damp kernels seals in the moisture, and mould appears in the pack rather than on your floor.
Kernels fully cooled
packing warm product causes condensation inside the pack. If the line runs roasting, this is the most common failure.
Correct seal temperature
too cool and the seal is weak, too hot and the film thins and splits along the seal.
Clean seal area
a single kernel fragment or a trace of oil across the seal line is enough to leak, and a slow leak is invisible until arrival.
Film specification
barrier properties matter. A cheap film with poor oxygen barrier undoes the nitrogen flush you paid for.
Maintenance
Replace seal bar PTFE and elements on schedule
worn elements give intermittent weak seals, which is worse than an obvious failure because it passes inspection.
Service the vacuum pump
oil changes on schedule; a tired pump takes longer to reach vacuum and slows the whole line.
Check chamber gaskets
a perished gasket means the chamber never reaches full vacuum and nobody notices until shelf life complaints arrive.
Verify residual oxygen periodically
the only way to confirm the flush is working is to measure it.
Keep the machine clean
kernel dust and oil accumulate around the seal area and are the usual cause of leaking packs.
Vacuum packing comes after colour sorting and metal detection — pack only product that has cleared both. For retail formats see pouch packing machine and retail packing.
The process, drawn
The packing end of the line
Four machines, often quoted as one. The sorting line ahead of the packer is the piece most commonly missed from a comparison.
TTQ builds vacuum equipment, not pouch machines or bags. Retail pouch formats are a separate class of machine from a different supply chain.
Where it fits in the process
Packing is the final stage. Graded, colour-sorted kernels arrive here and leave as sealed, labelled, export-ready lots — ready for the container.
