The 5L Edible Oil Linear Bottle Filling Production Line

The 5L edible oil linear bottle filling production line is a fully automated packaging system engineered for high-efficiency filling of 5-liter containers. It is designed to handle a wide range of edible oils, including corn oil, olive oil, peanut oil, sunflower oil, vegetable oil, and more . The line integrates multiple core units, typically including an unscrambler, bottle rinser, filler, capping machine, labeling machine, inkjet printer, and conveyor system, forming a seamless closed-loop from empty bottle handling to finished product packaging.

At the heart of the system is the linear filling machine, which employs either high-precision flowmeter or servo-driven piston/cylinder metering technology. The entire line is controlled by a PLC system with a user-friendly touchscreen interface, allowing operators to set filling volumes directly. This enables accurate and consistent filling with precision typically within ±0.5% or better . The filling heads feature advanced anti-drip designs with mechanical seals and vacuum suction to prevent oil leakage and waste. A dual-speed filling mode (fast then slow) ensures both high throughput and spill-free operation.

The line offers remarkable versatility. It supports quick changeover between different bottle sizes and shapes, with adjustable height, nozzle spacing, and clamping systems allowing fast switching—typically within 15 to 30 minutes. All components that come into contact with oil are constructed from food-grade SUS304 or SUS316L stainless steel, ensuring hygiene, corrosion resistance, and compliance with international food safety standards. Production capacity varies by configuration, ranging from 200 to over 2,000 bottles per hour . With its combination of automation, precision, flexibility, and sanitary design, this production line is an ideal solution for edible oil manufacturers seeking to enhance productivity and product quality.
