Most filling discussions start with bottles and small pouches. A different group of buyers fills 5-litre pails, 20-litre jugs and 30–50 kg drums: lubricants, detergents, base oils, sauces in food-service sizes, chemicals and cleaning concentrates. Filling these containers is closer to a weighing task than a dosing task, because at 50 kg the only reliable acceptance check is mass. This guide explains how a weighing filler differs from a volumetric or pump-metering filler for large containers, and what to verify before requesting a quotation for a pail or drum line.
1. Why large containers are a weighing problem
With a 50 kg fill, a 1% volume error is half a kilogram. Product density changes with temperature, supplier lot and — for many liquids — aeration. Pump-metered and volumetric routes accumulate exactly this kind of drift. A gravimetric filler weighs every container during filling and stops on target mass, so the batch record is produced by the machine rather than inferred from a calibration. For any container above roughly 5 kg, weigh-to-target should be treated as the default and volume-based dosing as the exception that needs justification.
2. Single-head or dual-head: match throughput, not catalogue size
Both approved MUJIU weighing models cover the same 5–50 kg range at a stated accuracy of ±0.2%, and both are semi-automatic: an operator places the pail or drum on the platform, the machine fills to the set mass, and the operator removes it. The difference is stations and pace.
| Model | Heads | Stated speed | Footprint (L×W×H) |
|---|---|---|---|
| AT-DGS-50Y | 1 | up to 6 barrels/min | 60×70×150 cm, ~100 kg |
| AT-2DGS-50Y | 2 | 0–12 barrels/min | 120×70×150 cm, ~200 kg |
Stated speeds depend on product, dose and pack format, so use them as relative guidance. The practical decision is simpler than the numbers: if your daily volume can be served by one filling position plus operator handling time, the single-head machine is the lower-risk purchase. Choose the dual-head version when a second filling position removes a queue — for example two operators exchanging containers, or one large-drum route beside a pail route.
3. Check your smallest size before committing to 50 kg
Weighing fillers have a lower comfort limit. Below about 5 kg, other approved MUJIU routes fit better: a desktop weighing filler such as the CSY-L36 covers 30 g–30 kg at ≤5 g accuracy on 110/220 V. If your order book mixes retail bottles and service pails, plan one container family per machine rather than asking a single filler to cover both extremes.
4. Product, container and interface questions
Liquid compatibility is defined by the weighing hopper and contact parts, so state the actual product — corrosive concentrates, oily or viscous sauces and solvents place different demands on seals and materials. Confirm your container profile: open-head vs. tight-head drums, pail handle position, fill-neck diameter and whether the container sits on the platform throughout the fill. Drip behaviour after cut-off matters more at drum scale than at bottle scale: a nozzle that strings will contaminate the platform and shift subsequent weights. Review the product-supply and pump checklist for the upstream supply boundary and the liquid-filling selection checklist for the general qualification sequence.
5. Verify with your own containers and product
Before treating a quotation as comparable, agree a sample check with your material: fill your heaviest and lightest target sizes several times, weigh each accepted container on your own scale, and record start/stop repeatability and any nozzle drip between fills. The liquid product sample data sheet gives a ready format for the inputs; the FAT acceptance checklist structures the final review. Both models list 1-year warranty, 1-unit MOQ and a 10-day lead time for one unit; multi-voltage configurations (220/380/415/440 V) should be confirmed for your destination supply before order.
Minimum drum-and-pail enquiry package
- Product name, viscosity behaviour, temperature and any corrosion or cleaning requirement for contact parts.
- Container list with nominal fill mass, tolerance and fill-neck geometry.
- Target containers per hour, single- or dual-operator pattern.
- Platform space, drainage and spill-handling constraints.
- Sample-check plan with the scale both sides will use.
Send your container list and product description to MUJIU. The goal is to confirm that weigh-to-target at your actual masses and pace is the right route before you compare prices.
