ZSYAN SY-HWDJ6000 Continuous Horizontal Produce Packaging Line
1. Quick Answer & Overview
Overview & Quick Answer: The ZSYAN SY-HWDJ series horizontal
mesh bag packaging machine is an industrial automated bagging system specifically engineered for continuous packaging of elongated agricultural produce and bundled materials into tubular knitted net bags. Operating across a throughput rate of 15 to 30 bags per minute with package weights from 1kg to 10kg and lengths up to 650mm, the system utilizes a synchronized horizontal lug conveyor to push products smoothly through a low-friction tubular netting former. Fabricated in heavy-duty AISI 304 stainless steel with Omron PLC control, pneumatic double galvanized wire-clipping jaws, and thermal label threading, it prevents snapping or jamming of fragile elongated produce. Operating on 0.65 MPa compressed air with 3.0 kW power draw, it displaces 3 manual bagging operators, achieving total capital investment recovery within 3.2 to 4.5 operational months in commercial packing operations.

Elongated items such as Dutch carrots, celery stalks, and kiln-dried firewood cannot tumble through vertical funnels without severe bridging or snapping. The horizontal architecture uses servo-timed pusher flights to guide aligned bundles horizontally directly into the continuous tubular mesh. Once the batch is inside, the pneumatic clipper simultaneously swages the trailing clip of the completed bag and the leading clip of the upcoming sleeve.

Direct horizontal engineering benchmark comparing ZSYAN equipment against conventional machinery and manual packaging:
| Performance Parameters | ZSYAN SY-HWDJ6000 / 7000 | Vertical Funnel Net Bagger | Manual Net Sleeve Stuffing Bench |
|---|
| Feeding Orientation | Horizontal continuous pusher lug | 90° vertical drop funnel | Manual hand sleeve stuffing |
| Operating Throughput | 15 – 30 bags/min (continuous cycle) | 8 – 12 bags/min (frequent bridging) | 3 – 5 bags/min per worker |
| Max Package Length | Up to 650 mm (continuous variable) | Max 300 mm (funnel restricted) | Variable / inconsistent |
| Produce Breakage / Snapping | < 0.2% (zero bending stress) | 4.5% – 8.0% (impact snapping) | 1.5% – 3.0% (manual forced entry) |
| Closure Mechanism | Pneumatic dual galvanized wire clip (SMC) | Heat seal / single clip | Manual plastic zip / hand knot |

4. Mathematical ROI & Payback
Financial payback model quantifying direct labor reduction, material optimization, and overfill elimination:
Direct Annual Net Savings (S) = [Labor Replacement] + [Produce Breakage Elimination] + [Netting Waste Reduction]
Where:
- Labor Replacement: 3 manual stuffing workers eliminated × $13,500 annual cost = $40,500
- Breakage Elimination: 5% snapping eliminated on 800 metric tons of export carrots ($0.45/kg) = $18,000
- Netting Waste: Uniform mechanical tension saving 14% tubular mesh material = $5,200
Total Annual Net Economic Benefit (S) = $63,700 USD
Machine Purchase Capital Expenditure (Capex) = $18,200 USD
Payback Horizon = (Capex / S) × 12 Months
= ($18,200 / $63,700) × 12 = 3.43 Months
For root vegetable washing plants and export packing houses, eliminating broken carrot tails and bruised celery stems directly salvages premium market prices. Capital expenditure amortizes in under 3.5 months of seasonal packing.

5. Engineering FAQs
Practical technical answers addressed to plant managers, automation engineers, and procurement directors (Click to expand technical response):
Long and brittle products tumble chaotically in vertical baggers, resulting in severe crosswise jamming inside the forming funnel and high tip breakage rates. The horizontal configuration aligns products parallel to the conveyor axis and injects them longitudinally into the mesh tube. Products experience zero vertical impact velocity and zero bending load, completely eliminating broken tips and jammed tubes.
The infeed flight conveyor features adjustable quick-release flights mounted on twin nickel-plated roller chains. Through the touchscreen interface, operators select the product recipe, and the servo motor automatically adjusts the indexing distance and bag clamp stroke to accommodate lengths from 150mm up to 650mm without swapping physical chains.
Yes. For heavy firewood packaging, the SY-HWDJ7000 is equipped with a heavy-gauge mandrel tube and high-tensile raschel netting guides. The bottom of the netting sleeve is supported by a continuous driven roller bed that supports the full 10kg weight during injection, relieving tensile strain from the mesh fabric and preventing burst seams.
The horizontal packaging machine includes an automated side-entry label applicator. As the bag neck is gathered horizontally by the pneumatic side jaws, a thermal ribbon wine-glass tag or printed plastic handle tape is positioned directly across the netting throat. The dual galvanized wire clip clamps through the label hole, anchoring the tag securely without puncturing the produce.
The primary lug conveyor chains utilize factory-sealed O-ring links that require only monthly wipedowns and food-grade mineral oil spray. The pneumatic clipping assembly requires weekly lubrication of guide pillars and regular inspection of the galvanized iron wire feeding rollers. The wire cutting blade is rated for 500,000 cuts and can be easily accessed from the side service panel.
