Edible oil nitrogen filling equipmentIt is a nitrogen preservation equipment designed specifically for the storage and filling of edible oils. With core characteristics such as precise nitrogen control, strong anti oxidation targeting, and adaptability to the characteristics of oils and fats, it effectively delays the oxidation and rancidity of oils and fats by filling inert nitrogen gas into oil bottles and tanks to replace oxygen. It is widely used in the production and storage of various edible oils such as peanut oil, soybean oil, olive oil, etc. It is a key equipment to ensure the shelf life and quality of edible oils. ​

Precise nitrogen control and anti oxidation structure are the core competitiveness. The equipment adopts an integrated design of "nitrogen generation purification precise filling": high-purity nitrogen with a purity of ≥ 99.9% is generated through a PSA pressure swing adsorption nitrogen production system, meeting the strict requirements for nitrogen purity in edible oil preservation; The nitrogen filling device is equipped with high-precision flow sensors and pressure regulating valves, which can accurately control the nitrogen filling amount according to the specifications and filling speed of the oil bottle, ensuring that the oxygen concentration in the bottle drops below 1%, greatly delaying the rate of oil oxidation. In response to the viscous and wall hanging characteristics of edible oil, the nitrogen filling nozzle adopts an anti drip design, combined with a tilted nitrogen filling angle, to avoid oil contamination of the nitrogen filling channel; Some models integrate pre vacuum function, which first extracts the air inside the bottle and then fills it with nitrogen to further reduce oxygen residue. In the olive oil filling production line, the shelf life of olive oil after nitrogen filling can be extended from 6 months to 12-18 months, while maintaining its original flavor and nutritional content. ​

Structural design suitable for oil production scenarios. The equipment can be flexibly configured according to the production scale of edible oil: small desktop nitrogen filling machines are suitable for the filling needs of small workshops, with simple operation and low cost; The large-scale fully automatic nitrogen filling unit can seamlessly connect with the edible oil filling production line, realizing the full process automation of "filling nitrogen filling sealing", with an hourly production capacity of 2000-8000 bottles. For the storage scenario of oil tanks, a dedicated nitrogen filling device for oil tanks is equipped. Nitrogen is slowly filled through a nitrogen pipeline that extends into the bottom of the oil tank, forming a uniform nitrogen protection layer to prevent oxidation of the upper layer of oil and grease inside the tank; At the same time, an online oxygen content monitor is equipped to monitor the oxygen concentration in the oil tank in real time. When the oxygen content exceeds the standard, nitrogen gas is automatically replenished. In the raw material storage tank area of large edible oil production enterprises, nitrogen filling equipment can effectively protect the quality stability of bulk oil raw materials during storage. ​

The safety, reliability, environmental protection, and energy-saving characteristics are outstanding. The edible oil nitrogen filling equipment is made of stainless steel 304 material, which contacts nitrogen gas and oil, is corrosion-resistant, and meets food grade hygiene standards; The nitrogen production system does not require chemical reagents and only produces nitrogen through air separation, which is environmentally friendly and cost-effective. Equipped with overload protection, abnormal pressure alarm and other safety devices to ensure stable operation of the equipment. In small and medium-sized edible oil factories, nitrogen filling equipment can be used to enhance product competitiveness and avoid return losses caused by oxidation; In the production of edible oil brands, nitrogen filling and preservation have become important guarantees for product quality, enhancing brand added value. ​
