How do I choose between single-lane, double-lane, and multi-lane granule packaging machines?

Choose based on your daily output: daily output up to 2,000 bags → single-lane SY-G2L180; 2,000-6,000 bags → double-lane SY-G2L240DL (best value); over 6,000 bags → multi-lane SY-ML series (4-8 lanes). More lanes does not always mean better — the right capacity match delivers the best return on investment.

Does multi-lane packaging machine have lower precision than single-lane?

No. This is a common misconception. ZSYAN cup metering systems use the same core technology across all models — servo-controlled cup positioning with real-time feedback adjustment. All lane configurations achieve ±1g accuracy: single-lane ±1g, double-lane ±1g (dual-lane sync), 4-lane ±1g (quad-lane sync), 6-lane ±1g, and 8-lane ±1g. Accuracy depends on the metering system and maintenance, not on lane count.

Which lane configuration offers the best cost-effectiveness for granule packaging?

Double-lane SY-G2L240DL offers the best value. Cost per bag per day is ¥21-28 for double-lane vs ¥28-38 for single-lane and ¥24-33 for multi-lane. Double-lane also has the fastest payback period at approximately 8 months, compared to 10 months for single-lane and 11-12 months for multi-lane. It delivers 2x single-lane capacity at less than 2x the price.

How much floor space does each granule packaging machine model require?

Single-lane SY-G2L180 requires approximately 2㎡. Double-lane SY-G2L240DL requires approximately 3.5㎡. 4-lane SY-ML400DL requires approximately 5㎡. 6-lane SY-ML600DL requires approximately 6.5㎡. 8-lane SY-ML800DL requires approximately 8㎡. If factory space is limited, single-lane or double-lane are the most practical choices.

What are real customer results for double-lane vs multi-lane granule packaging machines?

A Shandong seasoning factory needed 3,000 bags/day salt packaging. They chose double-lane SY-G2L240DL and achieved 4,500 bags/day with operators reduced from 3 to 1, payback in 9 months. A Sichuan spice factory needed 12,000 bags/day pepper grain packaging. They chose 6-lane SY-ML600DL and achieved 14,000 bags/day with ±1g accuracy and payback in 11 months.

Before Buying a Multi-Lane Granule Packaging Machine, Calculate This First

Before Buying a Multi-Lane Granule Packaging Machine, Calculate This First

I. Five Key Questions That Determine Your Selection Direction

Multi-lane granule packaging machines are not "the bigger the better." Choosing the right model maximizes your return on investment. Before contacting suppliers, answer these five questions:

What is my daily capacity requirement?
What materials am I packaging?
How strict are my accuracy requirements?
How much factory space do I have?
What is my budget range?

II. Question 1: Daily Capacity Requirement

This is the most important decision factor. First calculate your current demand, plus a 25% growth buffer:

Current daily production × 1.25 = Target daily capacity

Reference Standards:

Target Daily Output	Recommended Model	Speed Range
3,000-6,000 bags	Double-lane SY-G2L240DL	40-70 bags/min
6,000-10,000 bags	4-lane SY-ML400DL	80-120 bags/min
10,000-15,000 bags	6-lane SY-ML600DL	100-150 bags/min
15,000-20,000 bags	8-lane SY-ML800DL	150-220 bags/min

Warning: Do not blindly choose high lane count models. Excess capacity means wasted equipment investment. Insufficient capacity means peak season bottlenecks.

III. Question 2: Material Properties

Multi-lane granule packaging machines are suitable for free-flowing granular materials. Common applicable materials include:

Material Type	Particle Size	Flowability
Salt	0.1-2mm	Excellent
White Sugar	0.3-1mm	Excellent
Rock Sugar	1-5mm	Good
MSG	0.2-1mm	Excellent
Chicken Essence	0.5-3mm	Good
Pepper Grains	2-5mm	Good
Sichuan Peppercorn	1-4mm	Good
Dry Soup Packs	5-20mm	Fair

Materials NOT suitable:

Sticky materials (such as sesame paste)
Liquids (such as soy sauce)
Large chunk materials (such as whole garlic)
Highly dusty materials (such as ultra-fine flour)

IV. Question 3: Accuracy Requirements

The standard accuracy for multi-lane granule packaging machines is ±1g. For most seasoning packaging scenarios, this accuracy is completely sufficient.

If your customers have extremely strict weight requirements (such as pharmaceutical-grade products), you need to add a checkweigher, costing an additional ¥15,000-25,000.

V. Question 4: Factory Floor Space

The floor space of multi-lane packaging machines increases with lane count:

Model	Floor Space	Recommended Clearance
SY-ML400DL	~5㎡	Front 2m + Sides 0.8m each
SY-ML600DL	~6.5㎡	Front 2.5m + Sides 1m each
SY-ML800DL	~8㎡	Front 3m + Sides 1m each

Tip: Leave enough space for operation and maintenance.

VI. Question 5: Budget Range

Price range for multi-lane granule packaging machines:

Model	Price Range (RMB)
SY-ML400DL	¥145,000-175,000
SY-ML600DL	¥195,000-235,000
SY-ML800DL	¥245,000-295,000

Accessory Budget:

Vibrating hopper: ¥6,000-12,000
Conveyor belt: ¥4,000-8,000
Inkjet coder: ¥3,000-6,000
Checkweigher: ¥15,000-25,000

Total Investment Estimate = Main unit price + Accessory price + Shipping cost

VII. TCO Calculator: Three-Year Total Cost of Ownership

Taking SY-ML800DL as an example, three-year TCO estimate:

Item	Amount (RMB)
Equipment purchase	¥270,000
Shipping & insurance	¥15,000
Installation & training	¥5,000
Three-year energy cost	¥25,000
Three-year maintenance	¥18,000
Three-year consumables	¥12,000
Three-year total cost	¥345,000
Three-year labor savings	¥432,000
Three-year net benefit	¥87,000

VIII. Selection Checklist

Before contacting suppliers, please confirm the following information:

Daily capacity requirement (bags/day)
Packaging material type and particle size
Target bag weight range
Accuracy requirement (±1g or ±0.5g)
Available factory floor space
Budget limit
Whether accessories are needed (vibrating hopper, conveyor, coder, etc.)
Target delivery time
Whether multi-language interface is required

IX. FAQ

Q: How do I choose between multi-lane and double-lane? A: Choose multi-lane if daily demand exceeds 8,000 bags; choose double-lane for 2,000-8,000 bags for better value.

Q: Can a multi-lane machine package different products simultaneously? A: No. All lanes package the same product at the same time. But you can switch products quickly in different time periods.

Q: Is multi-lane machine maintenance costly? A: Annual maintenance cost is approximately ¥4,000-8,000 (seal strips, cutters, sensors, and other consumables).
