Indonesian Snack Factory Doubles Output with a Multi-Lane Granule Packaging Line
Customer Snapshot
A snack manufacturer in Surabaya, Indonesia, producing roasted peanuts, coated peanuts, cassava chips, and mixed nut packs for domestic retail and export to Malaysia and the Philippines. Monthly output: approximately 120 tons of finished snacks.
The factory ran three single-lane packaging machines of mixed age, each requiring separate operators and frequent manual intervention.
The Packaging Challenge
The factory's existing line had three bottlenecks:
Throughput ceiling. Three single-lane machines produced a combined 90 bags/min, but peak-season demand required 150+ bags/min. Overtime and a second shift could not close the gap.
Inconsistent weight. Older machines held +/-3-4g accuracy. For 60g snack bags, that was a 5-7% variance -- enough to trigger retailer complaints and absorb margin.
High labor intensity. Eight operators were required across three machines, plus two material handlers. Labor accounted for 11% of packaging cost.
Frequent changeovers. The factory ran five SKUs (peanut, coated peanut, cassava, mixed nut, and spicy mix). Each changeover on the old machines took 25-40 minutes and required recalibration.
Solution Configuration
ZSYAN proposed replacing the three old lines with one 4-lane granule VFFS system:
Machine: ZSYAN SY-GNL400 four-lane VFFS granule packaging machine
Filling: four independent servo auger/vibration feeders, +/-1g accuracy
Bag formats: 40g, 60g, 100g, 200g pillow bags with printed film
Changeover: 99 stored recipes; one-touch SKU switching
Downstream: checkweigher, metal detector, date coder, carton erector
Air and dust: centralized dust collection for coated peanut seasoning
Machine price: USD 28,000. Freight, installation, and commissioning: USD 4,500. Total project cost: USD 32,500.
Implementation Results
| Metric | Before (3 old lines) | After (1 x 4-lane) | Change |
|---|---|---|---|
| Output | 90 bags/min | 180 bags/min | +100% |
| Weight accuracy | +/-3-4g | +/-1g | 3-4x tighter |
| Packing staff | 8 operators | 3 operators | -62.5% |
| Changeover time | 25-40 min | under 5 min | -85% |
| Floor space | 3 lines | 1 line | -55% |
| Material waste | 2.8% | 1.1% | -61% |
ROI Analysis
| Cost / Saving Item | Monthly Amount (USD) |
|---|---|
| Labor saving (5 fewer operators) | 2,750 |
| Material saving (waste reduction) | 900 |
| Energy and maintenance saving | 350 |
| Total monthly benefit | 4,000 |
| Project investment | 32,500 (one-time) |
| Payback period | ~8.1 months |
The factory also avoided a planned USD 45,000 investment in a fourth single-lane machine and additional factory space.
What Made the Difference
Four lanes replaced three aging lines. The footprint reduction freed space for a new seasoning room, which the factory used to launch two additional flavors.
Independent lane control allowed mixed production. During low-demand periods, the factory runs two lanes instead of four, cutting energy use by 40%.
Recipe storage eliminated recalibration. Changeover dropped from 25-40 minutes to under 5 minutes, enabling smaller batch runs and faster response to retailer orders.
Integrated checkweigher caught drift early. The factory now rejects fewer than 0.3% of bags for weight, down from 2.1%.
Transferable Lessons
When three or more single-lane machines run the same product family, consolidate to a multi-lane system. The labor, space, and energy savings usually pay back in 8-12 months.
Specify independent lane control if your demand fluctuates. Running two of four lanes is far cheaper than running a full line at low utilization.
Include a checkweigher and metal detector from day one. Retail buyers increasingly require them, and retrofitting is more expensive.
Test coated and seasoned products specifically. Seasoning dust can clog feeders; centralized dust collection is essential.
FAQ: Common Questions
Q1: How many lanes do I need for 150 bags per minute? A: A 4-lane VFFS system typically produces 160-200 bags/min for 40-100g snack bags. A 3-lane system reaches 120-150 bags/min. For 150 bags/min with peak flexibility, 4 lanes is the safer choice.
Q2: Can a multi-lane machine run different products on different lanes? A: Yes. ZSYAN SY-GNL series supports independent lane recipes. You can run peanuts on lanes 1-2 and cassava chips on lanes 3-4, provided the film and bag format are compatible.
Q3: What is the price of a 4-lane granule packaging machine? A: A ZSYAN SY-GNL400 four-lane granule VFFS machine typically costs USD 24,000-32,000 depending on filling system and downstream equipment. Add 15-20% for freight, installation, and commissioning.
Q4: How long does installation take? A: Installation and commissioning typically take 5-7 days for a multi-lane line. Operator training takes 3 days. The customer in this case was producing saleable bags on day 6.
