One Jar of Salt, One Bag of Sugar, One Jar of Pepper — How a Double-Lane Granule Machine Serves Three Production Lines

One Jar of Salt, One Bag of Sugar, One Jar of Pepper — How a Double-Lane Granule Machine Serves Three Production Lines

A Seasoning Factory's Daily Dilemma

"We have three production lines: salt, sugar, and pepper. Each line requires the same packaging specification — 50g jars — but the material properties are completely different: salt flows freely, sugar tends to clump, and peppercorns are irregular and fragile."

This is the real-world feedback from a purchasing manager at a southern China seasoning factory. Three years ago, they operated three independent granule packaging machines, one for each line. Each machine required independent operation, maintenance, and spare parts inventory — management costs were extremely high.

Last year, they introduced one ZSYAN SY-G2L240DL double-lane granule packaging machine. With 99-recipe storage and dual independent cup metering, a single machine now serves all three production lines.

Core Capability One: Dual Independent Metering System

The core design of the double-lane granule packaging machine is dual independent cup metering working in parallel.

Unlike single-lane machines, the double-lane machine's two metering cups can operate independently without interference:

• Metering Cup A: Handles the salt line, 50g specification, accuracy ±1g

• Metering Cup B: Handles the sugar line, 50g specification, accuracy ±1g

• Or: Metering Cup A: Salt, Metering Cup B: Peppercorns (different specifications packaged simultaneously)

Why dual independent beats single-lane: A single-lane machine can only meter one material at a time, with a capacity ceiling of 20-35 bags/min. The double-lane machine's two metering cups work in parallel, doubling capacity to 40-70 bags/min. More importantly, the two cups can be set with different parameters — salt uses fast metering, peppercorns use slow metering, without interfering with each other.

Core Capability Two: 99 Recipes — One-Touch Changeover

The most common pain point for seasoning factories is frequent material changeover. One day producing salt, the next day MSG, the day after peppercorns. With a single-lane machine, each changeover requires recalibrating the metering cup, adjusting packaging parameters, and cleaning the feeding channel — the entire process takes 15-30 minutes and is prone to weight deviation from calibration errors.

ZSYAN SY-G2L240DL's 99-recipe storage solves this:

Recipe stored content:

• Metering cup capacity parameters (different for each material)

• Vibration feeder frequency (different frequencies for different flowability)

• Packaging speed settings

• Bag length parameters

• Coding date format

Changeover process:

1. Select the target recipe on the 7-inch touchscreen (e.g., "Salt-50g")

2. The machine automatically adjusts all parameters

3. Package 5 test bags for verification

4. Confirm accuracy and begin正式生产

The entire changeover takes approximately 2-3 minutes, far优于 manual calibration's 15-30 minutes.

Core Capability Three: Multi-Material Compatibility

Different granule materials have vastly different flowability:

• Salt: Excellent flowability, falls freely at high speed

• Sugar: Good flowability, but prone to clumping; requires vibration feeding

• Peppercorns: Irregular shape, moderate flowability, requires low-frequency vibration

• Sichuan pepper: Fine particles, prone to dispersion; requires enclosed feeding channel

• Dry soup packets: Regular block shape, good flowability, but significant weight variation

The double-lane granule packaging machine adapts to different materials through the following designs:

Vibration feeder system:

• Adjustable frequency (5-50Hz)

• Adjustable amplitude (adapted to different flowability)

• Enclosed feeding hopper (prevents peppercorn dispersion)

Metering cup design:

• Stainless steel material, easy to clean

• Detachable structure for快速 clearing during changeover

• Anti-residue design, cross-contamination rate below 0.1%

FAQ — Frequently Asked Questions

Q1: Can a double-lane granule packaging machine package two different materials simultaneously? Yes. The dual independent metering cup system allows both cups to be set with different parameters, packaging two different materials (e.g., salt and peppercorns) simultaneously. Capacity doubles without interference.

Q2: How many materials can the 99 recipes of SY-G2L240DL store? The 99 recipes can store packaging parameter combinations for 99 different materials. For small-to-medium seasoning factories, storing 20-50 commonly used recipes typically covers daily production needs.

Q3: Does the double-lane granule machine require cleaning during changeover? Yes. Although anti-residue design controls cross-contamination below 0.1%, different materials (especially switching from salt to peppercorns) still recommend a quick clear. The process takes approximately 3-5 minutes, including vibration feeder idling, metering cup emptying, and feeding channel blowing.

Q4: Is the double-lane granule machine suitable for small-batch multi-variety production? Highly suitable. The 99-recipe one-touch switching design is optimized for small-batch multi-variety scenarios. Compared to single-lane machines requiring 15-30 minutes of manual calibration, the double-lane machine completes changeover in 2-3 minutes, reducing changeover costs by over 80% for small-batch production.

Q5: How is the accuracy of the double-lane granule machine ensured? ±1g accuracy is ensured through the dual independent cup metering system. Each metering cup is equipped with a high-precision weighing sensor for real-time feedback adjustment of metering volume. Additionally, the 99 recipes allow optimized vibration frequency and metering parameters for different materials, ensuring all flowability types achieve ±1g accuracy.
