Full-automatic Specialized Filling Whole Line for Extra Virgin Olive Oil

Product Details
Extra virgin olive oil is extremely sensitive to light and oxygen. The open-type filling process of conventional edible oil filling machines easily exposes the oil to air for extended periods, accelerating oxidative rancidity and directly compromising the shelf life, flavor, and quality of the oil product. This fully automated filling production line, custom-engineered exclusively for premium olive oil, features nitrogen-purged and light-shielded designs across the entire workflow from empty bottle handling to case sealing. It minimizes the exposure of the oil to oxygen and light throughout the whole process, which not only precisely controls filling errors to reduce the loss of high-value oil, but also maximally preserves the natural active substances and delicate aroma of cold-pressed olive oil, drastically extending the product's shelf life.

Before filling, the equipment first injects food-grade inert nitrogen into the empty bottles to fully displace all air inside in advance. The entire filling process is completed under a slightly positive-pressure nitrogen protective environment. The filling head adopts a non-contact oil injection design below the liquid level, which lifts slowly from the bottle bottom while dispensing oil, completely eliminating the issues of splashing oil generating bubbles and introducing oxygen during the filling process. All pipelines and valve bodies that come into contact with olive oil are made of 316L medical-grade stainless steel, which features zero metal ion precipitation, excellent corrosion resistance to olive acid, and prevents the problem of oil contamination caused by inner pipeline wall oxidation even after long-term operation. The entire filling station is equipped with light-shielding protective covers to block direct light exposure to the oil during production, protecting the active components in olive oil from being destroyed by ultraviolet rays.

The whole machine is equipped with a high-precision weighing verification system, which automatically rechecks the weight of every filled bottle, and automatically rejects non-conforming products. The overall filling error is stably controlled within ±0.3%, and the long-term material loss of high-value olive oil can be kept below 0.3% — far lower than the 2% industrial loss level of conventional filling machines. All parts that come into contact with the oil are treated with mirror-polishing to eliminate dead corners, supporting tool-free quick disassembly for manual cleaning. A CIP (Clean-in-Place) module is also available as an optional configuration, enabling full pipeline disinfection without dismantling the machine, which fully meets the stringent hygiene standards for premium olive oil production. The entire line can flexibly adjust the station sequence according to the workshop layout of overseas customers, and is compatible with subsequent light-shielding labeling and gift box packaging equipment, creating a full-chain enclosed automated production solution for premium olive oil brands.

What Specifications Can We Customize for Overseas Buyers?
In response to the high-end production demands from different olive oil producing regions worldwide, we provide comprehensive exclusive flexible customization services, with core customization directions covering 4 major categories:

‌Customization for Exclusive Material Adaptation‌: For high-activity extra virgin olive oil and cold-pressed crude oil with trace olive pulp sediment, we customize fully enclosed nitrogen-purged flow channels, paired with a low-speed uniform material stirring system, to isolate oxygen throughout the process and prevent the oil from oxidation-induced discoloration and flavor deterioration.
‌Customization for Production Capacity and Containers‌: Based on the mainstream premium olive oil bottle types and gift box specifications in the customer's local market, we customize dedicated light-shielding positioning fixtures and filling strokes. The number of filling heads can be extended on demand from 2 to 10, with production capacity ranging from 600 bottles per hour to 2800 barrels per hour, which can accurately match the demands of small boutique olive oil estates as well as large high-end oil groups.

‌Customization for Regional Regulatory Compliance‌: For customers in high-end markets such as the European Union and North America, we upgrade the material of food-contact components to meet corresponding regional standards, provide complete EU food-grade material test reports and FDA compliance documents, and can be equipped with aseptic filling modules and full-machine explosion-proof modules as required, fully satisfying the stringent production supervision requirements for local premium oil products.

‌Customization for Localized Implementation‌: The equipment adapts to industrial voltage standards of different countries, features a built-in multilingual operation interface, and supports direct docking with the customer's existing third-party labeling and gift box packaging equipment, enabling rapid access without revamping the original production line. It can also be paired with a remote operation and maintenance module, with our overseas technical team available 24/7 online to quickly troubleshoot equipment faults.
