Edible Oil Filling Machine Line: Comparing 1–5L And 5-30L Capacities 

The edible oil industry demands precision, hygiene, and flexibility in packaging. Among the most widely produced formats are 1–30 liter bottles,pails,drums, which are the standard retail and bulk sizes for sunflower oil, soybean oil, canola oil, and other edible oils. To meet this demand, manufacturers invest in edible oil filling machine lines designed for different container volumes and based on varying filling principles. Choosing the right type of system is essential for balancing accuracy, efficiency, and cost.

Capacity Differences: 1L to 30L Bottles

The same filling machine line can often handle multiple sizes within the 1–5L range, but production speed and configuration vary:

• 1–5L Bottles – High demand for retail packaging requires faster filling speeds. Machines are typically designed with multiple nozzles to achieve higher throughput.

• 5–30L Jerrycans Or Tins – Larger bottles take more time to fill, so the system emphasizes accuracy and stability over extreme speed. In these formats, weighing and Magnetic Pump methods are often preferred to avoid costly overfill.

By adjusting conveyors, nozzles, and capping systems, one line can handle both small household bottles and larger family-size or catering packs.

Filling Principles: Piston, Weighing, and Magnetic

Different filling technologies are applied depending on oil characteristics and packaging needs. For 1–5L edible oils, the three most common methods are:

1. Piston Type Filling

• Works by drawing a precise volume of oil into a piston chamber and then pushing it into the bottle.

• Highly accurate for viscous or semi-viscous oils.

• Suitable for 1–5L bottles, especially when multiple sizes are required.

• Advantage: simple structure, reliable performance, consistent volume control.

2. Weighing Type Filling

• Each bottle is placed on a weighing scale, and the filler stops once the target weight is reached.

• Extremely accurate, minimizing product giveaway and cost loss.

• Best suited for large bottles (5-30L), where even small overfills can significantly impact profit.

• Advantage: compensates for bottle variations and ensures net content compliance.

3. Magnetic Pump Filling

• Uses electromagnetic Pump to measure liquid flow with high precision.

• Ideal for low-viscosity oils and high-speed production lines.

• Excellent for 1–30L bottles where fast filling and accurate dosing are essential.

• Advantage: contactless measurement, high accuracy, and less affected by container irregularities.

Capacity Differences: 1–5L vs. 5–30L Bottles

The same filling line can often be adjusted to handle multiple container sizes, but speed and accuracy differ significantly depending on bottle capacity:

• 1–5L Bottles

• Designed for high consumer demand in retail markets.

• Machines are typically equipped with multiple nozzles and can reach 1,000–5,000 bottles/hour depending on configuration.

• Emphasis on speed and flexibility, as bottles may vary between 1L household packs and 5L family-size packs.

• 5–30L Jerrycans or Tins

• Intended for bulk packaging, catering suppliers, or industrial buyers.

• Machines generally achieve 100–600 containers/hour, as filling a 20L or 30L pack takes much longer than a 1L bottle.

• Emphasis on weighing accuracy to avoid product giveaway, as even a small overfill translates into significant volume loss.

Essential Equipment in a 1–30L Edible Oil Filling Line

A complete edible oil filling machine line is not only about the filler. To operate smoothly, several machines are integrated:

• Bottle Unscrambler or Feeder – Automatically arranges plastic or PET bottles onto the conveyor.

• Edible Oil Filling Machine (Piston, Weighing, or Magnetic type) – Core unit for accurate dosing.

• Capping Machine – Tightens plastic screw caps, handle caps, or spout caps securely.

• Induction Sealing Machine (optional) – Adds tamper-proof seals, common for premium oil packaging.

• Labeling Machine – Applies product labels to bottles for brand visibility and compliance.

• Conveyor System – Links each machine into one continuous operation.

• Carton Packing & Sealing Machine (for larger lines) – Automates final case packing.

• Palletizer (for large-scale factories) – Stacks finished cartons onto pallets for efficient logistics.

Conclusion

The edible oil filling machine line for 1–30L bottles is versatile and adaptable, covering a wide range of consumer and commercial packaging needs. The choice between piston, weighing, or magnetic flowmeter filling depends on production goals—whether the priority is handling multiple sizes, minimizing giveaway, or achieving high-speed output. Supported by unscramblers, cappers, labelers, and packing systems, a well-designed filling line ensures that edible oils are packaged efficiently, safely, and attractively for the global market.
