"Our factory needs to produce 50,000 bags daily during peak season, but we cannot hire workers. Wages increase every year. Buying more single-lane machines? No floor space. Managing too many machines? Impossible."
This is the real dilemma faced by a large seasoning enterprise in central China. Producing 50,000 bags/day with single-lane machines at 35 bags/min, running 12 hours/day, requires at least 12 single-lane machines running in parallel — not including downtime for changeover, cleaning, and maintenance.
The solution is not buying more machines — it is using more efficient machines.
The multi-lane granule packaging machine (Multi-Lane Granule Packaging Machine) uses 4-8 lane parallel design, achieving 80-220 bags/min stable output on a single unit. Producing 50,000 bags/day requires only 1-2 machines.
The core of the multi-lane granule packaging machine is the multi-lane parallel metering system.
Structure principle:
4-lane model (SY-GDM400): 4 independent metering cups working in parallel
6-lane model (SY-GDM600): 6 independent metering cups working in parallel
8-lane model (SY-GDM800): 8 independent metering cups working in parallel
Each metering cup is independently controlled, equipped with an independent vibration feeder and weighing sensor. The PLC system coordinates all lane rhythms, ensuring stable parallel output.
Capacity calculation:
Single-lane capacity: 20-35 bags/min
4-lane capacity: 80-140 bags/min
6-lane capacity: 120-180 bags/min
8-lane capacity: 160-220 bags/min
For 50,000 bags/day, running 16 hours/day:
Required total capacity: 50,000 ÷ 16 = 3,125 bags/hour ≈ 52 bags/min
One SY-GDM400 (4-lane) can meet the requirement; recommending two units for changeover and maintenance buffering
The biggest technical challenge of multi-lane machines is cross-lane accuracy synchronization: with 8 metering cups working simultaneously, how to ensure every lane maintains ±1g accuracy?
ZSYAN's solution:
1. Independent weighing sensors Each lane is equipped with an independent high-precision weighing sensor, providing real-time feedback on actual weight. The PLC system adjusts metering volume based on feedback.
2. Dynamic compensation algorithm The PLC includes a dynamic compensation algorithm that automatically adjusts the next bag's metering parameters based on the previous bag's actual weight, ensuring long-term stability.
3. Regular calibration mechanism Every 500 bags, the system automatically runs a calibration verification. If deviation exceeds ±0.5g, the system auto-triggers a recalibration program.
Tested data: After 24 hours of continuous operation, the SY-GDM800's 8-lane average accuracy remains within ±0.8g, with best accuracy reaching ±0.5g.
Another challenge in high-yield mode is frequent changeover. Large seasoning factories typically produce salt, sugar, MSG, peppercorns, and other products simultaneously, requiring high changeover frequency.
ZSYAN SY-GDM series 99-recipe storage solves this:
Recipe stored content:
Each lane metering cup capacity parameters (can be set independently)
Vibration feeder frequency (adapted to different flowability)
Packaging speed settings
Bag length parameters
Coding date format
Changeover process:
Select target recipe on 7-inch touchscreen
Machine automatically adjusts all lane parameters
Package 5 test bags for verification
Confirm and begin正式生产
The entire changeover takes approximately 3-5 minutes, far优于 manual calibration's 20-30 minutes.

Q1: How does the multi-lane granule machine achieve cross-lane accuracy synchronization? Each lane is equipped with an independent high-precision weighing sensor. The PLC system adjusts metering volume based on real-time feedback. A built-in dynamic compensation algorithm automatically recalibrates every 500 bags, ensuring all 8 lanes maintain accuracy within ±1g.
Q2: How should I choose between SY-GDM400/600/800? The choice depends on daily capacity needs and product line count: SY-GDM400 suits factories producing 30,000-50,000 bags/day with fewer product lines; SY-GDM600 suits 50,000-80,000 bags/day with medium product line count; SY-GDM800 suits over 80,000 bags/day with a single or few product lines.
Q3: Does changeover on the multi-lane granule machine require downtime? Not complete downtime. The 99-recipe one-touch switching means selecting the target recipe on the touchscreen auto-adjusts all lane parameters. Changeover completes in approximately 3-5 minutes, after which production resumes.
Q4: How high is the maintenance cost of the multi-lane granule machine? Compared to multiple single-lane machines, multi-lane maintenance cost is significantly lower: spare parts require only 1 set (instead of 4-8 sets), annual maintenance费用 approximately USD 15,000-20,000, far below the USD 40,000-60,000 for 4 single-lane machines.
Q5: What products does the multi-lane granule machine support? Suitable for salt, sugar, rock sugar, MSG, chicken powder, peppercorns, Sichuan pepper, and various dry soup packets with good flowability. For sticky or clumping materials, confirm vibration feeder系统适配性 with ZSYAN technical team.
