Automatic Quantitative Packer

±0.2% weighing accuracy at 150–300 bags per hour.

  • 60+ years manufacturing
  • 10–500 t/d capacity range
  • 100+ patents
  • Turnkey commissioning

What it does

The packer is where a mill either makes or loses money quietly. A 0.2% accuracy figure sounds trivial until you calculate it against 60,000 bags a month — it is the difference between giving away product and being fined for underweight.

Technical parameters

Nominal values at standard conditions. Confirm final specification on the order drawing.

Model Output (bags/h) Power Accuracy Range Air supply
LCS5 200–300 3.2 kW ± 0.2% 1–10 kg 0.4–0.6 MPa
LCS25 150–220 3.2 kW ± 0.2% 10–25 kg 0.4–0.6 MPa
LCS50 150–180 3.2 kW ± 0.2% 25–50 kg 0.4–0.6 MPa

Selection guidance

For retail flour, specify the 5 kg unit with a bag-presenting carousel; for bulk, the 50 kg unit with a sewing head. Both need a stable 0.6 MPa air supply — under-supplied air is the most common cause of accuracy drift.

Maintenance

Calibrate with certified test weights weekly. Replace the load cell every 3–4 years; load cells drift silently before they fail.

Answers

Frequently asked questions

Straight answers to the questions engineers and mill owners actually ask us during plant sizing. If your case is not covered, send the wheat specification and your target tonnage.

What accuracy can I legally claim?
Pre-packaged goods regulations in most jurisdictions require the average net content to equal the declared weight, with a tolerated negative deviation. ±0.2% machine accuracy keeps you comfortably inside those limits.
