Many procurement managers make the wrong first step: blindly chasing high capacity and buying a multi-lane machine, only to find themselves with overcapacity, longer payback periods, and wasted budget.
The prerequisite for choosing the right model is calculating your actual needs.
Single-lane liquid packaging machines (SY-L180/SY-L240) cover daily capacity needs of 1,000-4,000 bags. If your factory falls in this range, single-lane is the optimal solution -- lowest price, smallest footprint, fastest payback.
First, calculate your daily capacity requirement:
| Daily Capacity Need | Recommended Model | Reason |
|---|---|---|
| 500-1,500 bags | SY-L180 | Speed 20-35 bags/min, sufficient for small-batch needs |
| 1,500-3,000 bags | SY-L240 | Speed 35-50 bags/min, mainstream choice |
| 3,000-5,000 bags | SY-L240 + dual-machine parallel | Or consider double-lane SY-LN400 |
| Above 5,000 bags | Multi-Lane SY-LNL series | Single-lane cannot cover this range |
Real Cases:
A Shandong seasoning factory needing 2,500 bags/day of sauce -> chose SY-L240 -> daily capacity 3,500 bags, with headroom for peak season
A Sichuan honey factory needing 1,200 bags/day -> chose SY-L180 -> daily capacity 1,800 bags, just enough
Different liquids have vastly different viscosities, which directly determines the configuration:
| Material Type | Viscosity | Recommended Config |
|---|---|---|
| Cooking wine, cooking oil | Low viscosity | Standard piston cylinder, standard config |
| Sauce, oral liquid | Medium-low viscosity | Standard piston cylinder + standard former |
| Honey, shampoo | Medium-high viscosity | Enlarged piston cylinder + optional heating |
| Cream, chemical reagent | High viscosity | Special piston design + heating system |
Important: Different viscosity materials require sample testing. ZSYAN provides free material compatibility assessment.
| Accuracy Level | Application | Recommended Model |
|---|---|---|
| +/-1% (standard) | Seasonings, cooking oil, cooking wine | SY-L180/SY-L240 standard config |
| +/-1% (high precision) | Oral liquids, premium cosmetics | SY-L240 + precision piston cylinder |
| +/-0.5% (ultra high precision) | Pharmaceutical-grade | Special customization (negotiable) |
Note: Single-lane and double/multi-lane both achieve +/-1% accuracy. Lane count does not affect accuracy.
| Budget Range | Recommended Solution |
|---|---|
| USD 6,000-8,000 | SY-L180 basic config (machine + hopper) |
| USD 8,000-11,000 | SY-L240 standard config (machine + hopper + conveyor) |
| USD 11,000-14,000 | SY-L240 full config (including coder + long conveyor) |
| USD 14,000+ | SY-L240 x 2 or double-lane SY-LN400 |
| Parameter | SY-L180 | SY-L240 |
|---|---|---|
| Lanes | 1-lane | 1-lane |
| Speed | 20-35 bags/min | 35-50 bags/min |
| Daily Capacity (10h) | 1,200-2,100 bags | 2,100-3,000 bags |
| Accuracy | +/-1% | +/-1% |
| Screen | 7-inch color touchscreen | 7-inch color touchscreen |
| Recipe Storage | 99 groups | 99 groups |
| Material | 304 stainless steel | 304 stainless steel |
| Dimensions | 1700x1200x1700mm | 1700x1200x1700mm |
| Weight | 600kg | 600kg |
| Power | 2-5KW | 2-5KW |
| Price | USD 6,000-8,000 | USD 8,000-11,000 |
| Payback Period | 4-6 months | 5-8 months |
Key Difference: SY-L240 runs faster, suitable for factories needing over 2,000 bags/day.
` Step 1: What is your daily capacity need? +-- < 1,500 bags -> SY-L180 (entry-level value) +-- 1,500-3,000 bags -> SY-L240 (mainstream choice) +-- > 3,000 bags -> Consider double-lane SY-LN400 or multi-lane SY-LNL series
Step 2: What is your material viscosity? +-- Low viscosity (cooking wine, oil) -> Standard config +-- Medium viscosity (sauce, oral liquid) -> Standard config +-- Medium-high viscosity (honey, shampoo) -> Enlarged piston cylinder + optional heating +-- High viscosity (cream) -> Special design + heating system
Step 3: What is your budget? +-- Under USD 8,000 -> SY-L180 basic config +-- USD 8,000-11,000 -> SY-L240 standard config +-- USD 11,000-14,000 -> SY-L240 full config +-- Above USD 14,000 -> Dual-machine parallel or double-lane model `
Many customers only consider equipment price and overlook these hidden costs:
| Item | Cost (Reference) | Necessary? |
|---|---|---|
| Vibrating hopper | USD 700-1,100 | Recommended, improves feeding efficiency |
| Conveyor belt | USD 400-800 | Recommended, auto-collects finished bags |
| Coder | USD 400-700 | Necessary, production date traceability |
| Installation & commissioning | Usually included | -- |
| Training | Free | ZSYAN remote training |
| Spare parts kit (first year) | USD 280-550 | Recommended, seals and wear parts |
| Shipping | Depends on destination | Necessary |
Total budget estimate: Equipment price + accessories = 110%-130% of equipment price
