Edible Oil Filling Methods Comparison Table
| Filling Method | Principle | Features | Applicable Viscosity | Filling Accuracy | Production Speed | Equipment Cost | Liquid Level Consistency | Filling Range | Applicable Products |
|---|---|---|---|---|---|---|---|---|---|
| Flow Meter Filling | Uses a flow meter to measure the amount of oil passing through in real-time, controlling valve opening and closing to achieve quantitative filling. | – High accuracy (within ±0.2%, highest precision) – Suitable for various viscosities – High-speed filling – Equipment cost is relatively high |
All viscosities (suitable for low to high viscosity liquids) | High (within ±0.2%, highest precision) | High speed (suitable for mass production) | High (large investment cost) | General (liquid level may vary slightly) | Generally suitable for medium to large volumes (e.g., 100 ml to 5 liters) | High-value, high-precision oils like olive oil |
| Piston Filling | Uses the reciprocating motion of a piston within a cylinder to suck in and extrude a fixed amount of oil. | – Relatively high accuracy (within ±0.5%) – Wide viscosity range – Simple structure, easy maintenance – Medium filling speed |
All viscosities (suitable for low to high viscosity liquids) | Relatively high (within ±0.5%) | Medium speed (suitable for medium output) | Medium (moderate investment cost) | General (liquid level may vary slightly) | Suitable for small to large volumes (e.g., 50 ml to 5 liters) | Various edible oils like peanut oil, rapeseed oil |
| Gravity Filling | Utilizes the liquid’s own gravity, controlling filling time and liquid level to achieve quantitative filling. | – Low cost, simple structure – Suitable for low-viscosity liquids – General filling accuracy – Slower speed |
Low viscosity (suitable for liquids with good fluidity) | General (within ±1% or above) | Low speed (suitable for small batch production) | Low (small investment cost) | General (liquid level may vary slightly) | Best for larger volumes (e.g., 500 ml to 5 liters or more) | Low-viscosity edible oils and beverage products |
| Weighing Filling | Real-time weighing during filling; stops filling when the set weight is reached. | – High accuracy (within ±0.2%, highest precision) – Not affected by density or temperature – Suitable for various viscosities – High equipment cost – Slower filling speed |
All viscosities (suitable for low to high viscosity liquids) | High (within ±0.2%, highest precision) | Low speed (suitable for small batch production) | High (large investment cost) | General (liquid level may vary slightly) | Suitable for large volumes (e.g., 1 liter to 20 liters) | Edible oils requiring high precision, like premium olive oil |
