Automatic 8-Lane Milk Powder Packing Machine (Multi-Track VFFS) for Small Sachets

What this machine does—at a glance

An 8-lane, multi-track VFFS (vertical form-fill-seal) line forms, fills, and seals small powder sachets in parallel. It’s purpose-built for milk powder, protein powder, instant drink mixes, and fine chemical powders—delivering high output, consistent weight accuracy, and clean, hermetic seals on laminated plastic foil.

Key performance data (typical configuration)

• Lanes: 8 tracks (independent forming sets)

• Output: up to 320–480 sachets/min total (40–60 cycles/min per lane, product/film dependent)

• Dose range: 2–50 g (auger filler), optionally up to 100 g with larger screws

• Fill accuracy: typically ±0.2–0.5 g (steady humidity, proper dust extraction)

• Sachet format: 3-side seal or 4-side seal

• Sachet size (per track): width 30–80 mm, length 60–160 mm (format-set dependent)

• Film type: laminated plastic foil (e.g., PET/AL/PE, OPP/AL/PE, Paper/AL/PE)

• Utilities: 380–480 V, 50/60 Hz; clean, dry air 0.6–0.8 MPa

• Footprint: compact multi-lane frame with guarding; integrates upstream/downstream

Why multi-track VFFS for dairy & nutrition powders

• Throughput without more floorspace. Eight lanes run simultaneously, multiplying output versus single-lane machines.

• Repeatable dosing in dusty products. Servo augers with agitation maintain a stable powder column for precision.

• Premium retail finish. Four-side or three-side seals with crisp registration for brand-forward sachets.

• Cost per pack advantage. High OEE and fewer operators drive lower unit costs for trial packs and sample sizes.

Product & packaging compatibility

Powders handled

• Skim/whole milk powder, whey, caseinates

• Protein powder blends (whey, soy, pea)

• Cocoa, instant coffee, creamer mixes

• Fine chemicals and lab powders (non-hazardous)

Packaging materials

• Plastic-foil laminates (barrier to oxygen, light, and moisture)

• Optional easy-tear notches, rounded corners, or laser scoring

• In-line date/lot coding (inkjet or TTO), QR/Datamatrix, and tear-assist

---

Hygiene, safety, and compliance by design

• Dust-tight enclosures with central extraction to keep heads clean and weighers precise

• HEPA H13 filtration at the dosing zone (optional)

• Contact parts in SS304/SS316, tool-less removal for washdown

• GMP-oriented layout; supports HACCP documentation and US/EU food safety norms

• CE electrical safety; food-grade seals and gaskets available

---

Accuracy & weight control stack

1. Servo auger dosing with level probes and agitation for flow-challenged powders

2. Target-weight auto-tuning (closed-loop trim via checkweigher feedback)

3. Statistical process control (SPC) dashboard; alarms on drift/out-of-tolerance

4. Optional dual-stage weighing: auger bulk + fine-trim pulse for micro-doses

---

Film handling & registration

• Independent film unwind per lane for stable web tension

• Photocell registration for perfect logo alignment on each sachet

• Smart temperature control to protect foil laminates and ensure tight seals

---

Typical line integration

• Infeed: spiral conveyor, de-dusting, de-humidified hopper

• Dosing: multi-lane servo augers with quick-change screws and tubes

• VFFS: 8 forming sets, heated jaws, and vertical/horizontal sealers

• Inspection: in-line metal detector and checkweigher

• Discharge: synchronized conveyors to cartoners or flow-wrappers

• Coding & vision: TTO/inkjet, camera for print/lot verification

Clean changeovers for short runs

• Format-set swaps (forming tubes & jaws) in ~20–30 minutes with alignment guides

• Recipe memory (dose, temps, jaw pressure, registration) for SKU recalls

• Color-coded contact parts to safeguard allergen control plans

---

Controls, data, and uptime

• PLC + 10–15″ HMI with multi-language UI and guided wizards

• OEE, scrap, and weight-variance dashboards; export via Ethernet/OPC UA

• Predictive maintenance prompts on cycles/temperatures/drive loads

• e-Stops, interlocked doors, and safe-speed jog for technicians

---

Example ROI snapshot (illustrative)

• Output: 400 sachets/min, 8 hrs/day → 192,000 sachets/day

• Labor: 2 operators/shift vs. 4 on semi-auto → labor savings ≈50%

• Film & product waste reduced 1–2% via registration and weight control

• Payback: 12–18 months typical for dairy/nutrition SKUs with >1.5M sachets/month

(Your actual ROI depends on SKU, film width, sachet size, and dose variance targets. Get an exact pro-forma from HMD Packaging Machine.)

Is an 8-lane machine right for you?

Choose 8 lanes when you need high volumes of small sachets (sampling, single-serve, hotel, retail trial, or e-commerce kits) and want to lower cost per pack without adding extra floorspace. If you run larger doses or need future flexibility, consider modular 6- or 10-lane variants built on the same platform.
