Vegetable Oil Filling Machine

Our vegetable oil filling machines handle all common edible vegetable oils: sunflower oil (high-oleic and standard), soybean oil, corn oil, canola/rapeseed oil (refined), vegetable oil blends (any ratio), cottonseed oil, rice bran oil, sesame oil (light). For olive oil (especially extra-virgin), we recommend our dedicated olive oil bottling machine with nitrogen flushing capability. For palm oil, which semi-solidifies below 25°C, the heated palm oil filling system is required. All other common vegetable oils remain liquid at ambient temperature and are handled by standard vegetable oil lines.

Flow meter filling measures volume flow through a Coriolis or electromagnetic flow meter and fills to a set volume. It is faster and well-suited for consistent-density single-origin oils where density does not vary significantly batch-to-batch. Net-weight filling weighs each container during the fill cycle and stops when the target weight is reached. It is often preferred for blended oils where blend ratio affects density and for markets with strict net-weight labeling requirements. The final accuracy target should be confirmed after oil density, temperature range, bottle format, and acceptance method are reviewed.

Vegetable oil lines use a simplified flush-based cleaning protocol (not full CIP with water and detergent, which would contaminate oil lines with water residues). Between oil types of the same grade family (e.g., switching between two soybean oil brands), a product flush of 20–50L of the incoming product through all lines clears residual previous product. For switching between oil categories (sunflower to palm oil) or after maintenance shutdowns, a food-grade flushing oil (light mineral oil or a dedicated oil-line flush product) is circulated to remove residues before introducing the new product. Full water-based CIP is only used for annual deep cleaning or before extended shutdowns.

The required documentation depends on the target export market, production site, and buyer acceptance process. EU projects typically require machinery safety and EMC documentation; food production projects usually require product-contact material records and hygiene documentation; the United States may require food-contact material traceability; Russia and CIS projects may require local conformity files. HEMU should confirm the required document set during RFQ review instead of assuming one universal certificate package for every line.
