An edible oil filling machine is a broad category that encompasses equipment for packaging any oil intended for human consumption, including vegetable, olive, coconut, and peanut oils. The paramount concerns are hygiene, accuracy, and preservation of oil quality. The machine must be constructed according to food-grade standards, using AISI 304 or 316 stainless steel and food-safe seals. The filling technology must be precise to avoid giveaways and ensure compliance. To maintain the oil's freshness, many modern edible oil fillers incorporate an nitrogen inerting system. This technology floods the bottle with nitrogen gas just before filling to displace oxygen, and can also blanket the oil in the storage tank. This prevents oxidation, which causes rancidity and spoilage, significantly extending the product's shelf life without the need for preservatives. Ace-Filling provides solutions tailored to the edible oil industry, from semi-automatic machines for artisanal producers to fully automated lines for large refineries. These systems are designed not just to dispense oil, but to protect its quality from the moment it is filled until it is opened by the consumer, ensuring a premium product experience.
