CE Factory Customizable Automatic Weighing Filling Packing Machines (For Nuts, Granules, Candy & Food Oil in Plastic/Glass Jars)

If you’re packing nuts, granules, candy, or food oil into plastic or glass jars, the biggest bottlenecks usually show up in three places: inconsistent fill weight, messy changeovers, and slow throughput. A customizable automatic weighing + filling + packing line fixes those issues by combining accurate dosing, hygienic product handling, and stable jar transport—so you can scale output without sacrificing quality.

Who These Machines Are Built For

These jar lines are designed for end users such as:

• Food factories producing nuts, seeds, granules, spices, sugar, coffee beans

• Candy and snack producers filling hard candy, gummies, pellets, coated snacks

• Edible oil and sauce makers filling food oil, chili oil, honey, syrups, dressings

• Co-packers and private-label brands needing fast changeovers across SKUs

• Businesses upgrading from semi-auto filling to fully automatic production

If your goal is fewer operators, better consistency, and predictable output, a complete line (not just one machine) is usually the fastest route to ROI.

What “Automatic Weighing + Filling + Packing for Jars” Means

A full jar solution typically includes these modules:

• Product feeding system (hopper + elevator/feeder)

• Weighing or dosing system (depending on product type)

• Filling unit (granule filler or liquid/oil filler)

• Jar handling (infeed, positioning, conveyors)

• Capping / sealing options (capper, induction sealer, heat seal as needed)

• Optional labeling and coding (labeler, date/lot coder)

The key is matching the dosing method to the product—because “nuts” and “oil” require completely different filling technology.

Best Filling Method by Product Type

Nuts, Granules, Candy (Discrete Pieces)

For jar filling with piece-based products, the most common approach is:

• Multihead weighing (combination weigher) for speed + accuracy

  • Typical target performance in real production: ±0.3–1.0% depending on product consistency and target weight

• Linear weighers for lower speed and lower cost

• Volumetric cup fillers for very uniform granules where cost is priority

Why it matters: Accurate weighing reduces giveaway. Even a small improvement (for example, reducing overfill from 2–3% down to ~1%) can create meaningful savings over high monthly volumes.

Food Oil (Liquid)

For oil and other liquids, common solutions include:

• Piston filling for accurate, repeatable volumes on medium-viscosity liquids

• Flowmeter filling for high accuracy and clean control at higher speeds

• Gear pump filling for thicker oils and better anti-drip performance

Why it matters: Oil needs clean cut-off, anti-drip nozzles, and stable jar indexing to prevent mess, label rejection, and cleaning downtime.

Key Benefits End Users Usually Care About

1) Stable Output (Without Quality Drops)

A properly configured automatic line can support continuous production with consistent jar positioning, controlled dosing, and fewer stops—especially compared to manual filling where variation increases as operators fatigue.

2) Cleaner Production and Easier Compliance

Food-contact parts are typically built with food-grade stainless steel (commonly SS304, with SS316 available for more demanding products), plus smooth surfaces to reduce residue buildup. This is helpful when you need reliable sanitation routines and cleaner audits.

3) Faster SKU Changeovers

Smart customization focuses on quick adjustments:

• Recipe memory / parameter presets (where applicable)

• Tool-less hopper access

• Quick nozzle swaps (liquid)

• Faster weigher tuning (granules)

Even saving 10–20 minutes per changeover adds up quickly when you run multiple SKUs daily.

4) Lower Labor Dependence

A complete jar line often reduces operator requirements to feeding, monitoring, and packing-out—rather than manual weighing and filling.

What “CE Factory Customizable” Should Include

When you see “CE” and “factory customizable,” you should expect:

• Guarding + emergency stops + safety interlocks on moving sections

• Electrical layout and protection designed for industrial use

• Adjustable format parts for different jar diameters/heights

• Multiple dosing options so the line fits your product today and can expand later

How to Choose the Right Configuration (Simple Buyer Checklist)

Before requesting a quotation, prepare these details:

1. Product

• Nuts / granules / candy type, piece size, stickiness, oiliness, dust level

2. Jar

• Material (plastic or glass), mouth diameter, height, shape, cap type

3. Target fill

• Net weight or volume per jar (and acceptable tolerance)

4. Required speed

• Jars per minute/hour target, shift length, and peak season demand

5. Sealing needs

• Cap only, induction seal, liner, tamper-evidence, or foil seal

With that information, it’s much easier to match you with the correct weigher/filler and ensure the line runs smoothly in real production.

---

Typical Line Options You Can Add Later

A scalable system often allows add-ons like:

• Induction sealing for leak prevention and tamper evidence

• Labeling + date/lot coding for retail readiness

• Checkweigher for in-line verification and reduced compliance risk

• Turntable / accumulation table for smoother downstream packing

• Nitrogen flushing (for some dry snacks) to support shelf life goals

If you want a line that grows with you, plan the layout with expansion in mind from the beginning.

Next Step: Get a Jar Line Matched to Your Product

The “best” machine isn’t the one with the highest speed on paper—it’s the one that runs your product cleanly, hits your target weight reliably, and changes over fast enough to keep your schedule on track.
