Core Application Features of the Edible oil bottle filling machine
Adaptive Filling for Viscous Fluids
For high-viscosity oils such as soybean oil and peanut oil, this edible oil bottle filling machine utilizes a piston-type design that adjusts the compression ratio to eliminate air bubble interference and ensure splash-free filling.
Adapting to a dynamic viscosity range of 5 to 200 cP, it allows for quick switching between sunflower oil (low viscosity) and sesame oil (high viscosity) without component replacement.
Gravity-Pressure Dual-Mode Filling Mechanism
Normal Pressure Mode: Suitable for standard PET bottles, it relies on gravity flow for smooth filling, with a residual volume of ≤0.1 mL at the bottle neck.
Negative Pressure Mode: Suitable for 200L metal drums, it activates a vacuum adsorption system to eliminate backwash, increasing flow rates by 40% and eliminating foaming.
Integrated Oxidation Protection System
The filling valve features a built-in nitrogen circulation channel to achieve headspace gas replacement (oxygen content ≤0.5%) before an oil film forms, extending the shelf life of high-end oil products by over 30%.
Precise Positioning of Heavy-Loaded Containers
The hydraulic lifting platform is equipped with adaptive V-grooves, compatible with both square and round barrels (300-600mm diameter). A positioning error of ±0.5mm prevents dripping caused by barrel mouth deviation.
Temperature Differential Volume Compensation Technology
An embedded temperature sensor monitors oil temperature in real time (0-50°C) and automatically corrects volume deviations caused by thermal expansion and contraction (compensation coefficient 0.00075/°C), ensuring consistent filling accuracy in winter and summer.
Tool-less Quick-Change Structure
The filling head and metering pump utilize a magnetic coupling interface. Changing valve nozzles of different sizes (Ø10-50mm) requires only a twist of the latch, with a changeover time of less than 3 minutes.
Dry-Run Protection Mechanism
Automatically shuts down when oil supply line pressure drops below 0.15MPa to prevent idling and wear on the ceramic plunger. Intelligent refilling upon oil supply restoration eliminates short-circuited bottles.
Irreplaceable Functional Value
Physical anti-mixing design: Different oil types are independently circulated in the filling pipeline (no intermediate buffer tank), eliminating cross-contamination at the source.
Overpressure relief valve: Automatically releases pressure when the oil pipeline pressure exceeds 1.2 times the rated value, protecting precision metering components.
Catalyst residue control: All oil line contact surfaces are electrolytically polished to Ra ≤ 0.4μm, eliminating the risk of metal ion catalytic oxidation.
