Complete Industrial Production Line for Automated Weighing and Bag Packaging of Salt
Automated feeding metering sealing inspection coding palletizing. One-stop integration for edible and industrial salt.
Get a custom quoteManual weighing and sealing often cause weight deviation and weak seals, while open handling risks moisture pickup and contamination. Our automated solution raises throughput to 100–150 bags per minute, holds weight accuracy within ±0.3 g, and ensures closed transfer from hopper to finished bag for hygiene compliance.
| Model | Salt types | Speed | Range | Accuracy | Bag styles | Highlights |
|---|---|---|---|---|---|---|
| SPX-600 | Refined edible salt iodized salt | 100–120 bags/min | 100 g–3 kg | ≤ ±0.3 g | 3-side seal back seal | Dynamic weighing compensation PLC touch panel |
| SPX-900 | Sea salt rock salt industrial salt | 120–150 bags/min | 500 g–10 kg | ≤ ±0.5 g | Doypack zipper stand-up | Anti-caking feed screw constant-temperature sealing |
Upstream salt conveying before packaging
All contact parts use 304 stainless steel. Closed hoppers and dehumidified air help reduce moisture pickup and clumping. The control cabinet supports recipe management, remote diagnostics, and line OEE reporting. Optional metal detector and checkweigher provide reject control.
Vacuum loader with anti-stick piping 0–500 kg/h adjustable.
Two-stage auger plus load cell 0.1 g resolution.
80–180 °C constant temperature 0.3–0.5 MPa pressure seal strength ≥ 35 N/15 mm.
Checkweigher metal detector seal integrity automatic reject.
Laser date lot QR for traceability ERP ready.
Robotic palletizer ±5 mm accuracy 10 boxes per layer.
Small packs 250 g to 1 kg with date and lot coding for retail.
10–25 kg laminated sacks for water treatment and deicing.
Granular or block lines with customized labeling.
- Daily output raised from 24,000 to 250,000 bags in peak season.
- Loss rate reduced from 3% to 0.2% with closed transfer and weighing control.
- One inspector per line saves annual labor cost while improving consistency.
