ZSYAN SY-LML600DL Multi-Lane High-Output Liquid Stickpack Packaging System
1. Quick Answer & Overview
Overview & Quick Answer: The ZSYAN SY-LML600DL multi-lane liquid packaging machine is a high-speed multi-track vertical form-fill-seal system built for simultaneous 4 to 10 lane volumetric filling and hermetic packaging of liquid and viscous products into slender stickpacks. Operating at an aggregate production throughput of 120 to 400 sachets per minute across a 1ml to 50ml dosing capacity per lane, the machine integrates a multi-cylinder servo piston manifold, precision rotary distribution valves, individual pneumatic shut-off suck-back nozzles, and multi-zone PID heated sealing rolls within an AISI 304/316L stainless steel enclosure. Controlled by a 10-inch Omron multi-axis motion controller with real-time pressure diagnostics, it holds dosing accuracy within ±0.8% across all lanes while eliminating leakage risks. Operating on 0.65 MPa air with 5.5 kW power consumption, it displaces up to 8 single-lane liquid machines, amortizing capital investment within 2.4 to 3.8 operational months in enterprise packaging operations.

The workflow architecture maps ZSYAN's balanced fluid distribution sequence. Pressurized liquid from the jacketed reservoir is drawn simultaneously into a multi-cylinder block. Individual micro-adjustable piston strokes ensure uniform volumetric displacement across every lane, while pneumatic shut-off suck-back tips guarantee zero fluid contact with heated seal edges.

4. Mathematical ROI & Payback
Financial payback model quantifying direct labor reduction, material optimization, and overfill elimination:
Direct Quantified Economic Benefits (Basis: 6-lane model, 1.2M honey/syrup stickpacks/month, 15ml):
1. Cleanroom Labor Reduction: 5 manual filling & packaging attendants displaced ($14,500 annual wages each) = $72,500 USD/year
2. Liquid Giveaway & Drip Elimination: Average overfill reduced from +0.8ml to +0.1ml (0.7ml saved per stick across 14.4M sticks/year @ $0.0015/ml) = $15,120 USD/year
3. Defective Pouch Prevention: Pouch burst & seal contamination dropped from 2.5% to 0.1% (345,600 leaked pouches avoided @ $0.035 empty film value) = $12,096 USD/year
Total Annual Net Economic Benefit (S) = $99,716 USD
Equipment Procurement Capital Expenditure (Capex) = $29,800 USD
Payback Horizon = (Capex / S) × 12 Months
= ($29,800 / $99,716) × 12 = 3.59 Months
By deploying the SY-LML600DL, automated packaging lines amortize initial capital acquisition within 4 months of standard single-shift operation. In high-volume packaging applications, complete payback is achieved in less than 65 operating days.

5. Engineering FAQs
Practical technical answers addressed to plant managers, automation engineers, and procurement directors (Click to expand technical response):
The SY-LML600DL incorporates a heavy-duty servo linear actuator driving a unified high-rigidity piston bridge. Individual piston cylinders feature micro-threaded stroke adjustment micrometers. During commissioning, operators calibrate each individual track with high-precision graduated cylinders, locking each lane within ±0.05ml repeatability across the entire machine array.
The machine utilizes interchangeable rotary valve cores paired with variable servo velocity profiles. For thin water-like fluids, the piston accelerates quickly with a gentle deceleration curve to avoid bubbling; for high-viscosity honey or collagen paste, the cylinder draws fluid at low vacuum speed and injects through heated nozzle jackets up to 75°C to optimize laminar flow.
Each filling lance is equipped with a pneumatic poppet suck-back valve seated at the nozzle tip. Liquid flow is severed instantaneously when injection terminates, while the machine's film advance motion profile smoothly accelerates the pouch sleeve downwards, ensuring liquid settles below the heat seal line before the cross-sealing rollers press the film.
Yes. The horizontal cutting array can be equipped with modular punch dies. Supported options include micro-zigzag easy-tear edges, European-standard hanging holes, V-shaped tear notches, or multi-pack perforated tear-off chains (e.g. 5 connected sticks per strip) driven automatically by the PLC program.
The system features a built-in automated CIP sanitation loop. Operators connect the inlet manifold to plant hot water and sanitizing chemical lines. Controlled via a dedicated touchscreen CIP routine, the piston pump cycles continuously at 80°C, thoroughly scouring all manifolds, rotary valves, and nozzle tips in under 20 minutes with zero manual teardown required.
