Which oils can share one filling machine?

As a rule, oils that share the same category and have similar viscosity/formulation can run on the same oil filling machine.

• Edible Oils(food-grade): Canola, soybean, olive, sunflower, peanut, etc. These can run on the same edible oil filling machine when paired with food-grade contact parts (SUS304/316) and cleaning.
  

• Industrial Oils: The same type of industrial oils (Such as lubricant, engine oils, etc.) may share a filling machine.
  
  NEOSTARPACK’s recommendation: Before sharing a filler, assess viscosity range, additive compatibility, and aroma/allergen risks (e.g., peanut oil). Plan an appropriate cleaning SOP and keep multiple, color-coded wetted-part kits (tubing, gaskets, nozzles) for quick, error-proof changeovers.

Why don’t we share a filling machine among distinct kinds of oils?

• Risk of Cross Contamination: Different oils may contain distinct additives, allergens, or residual impurities. Sharing equipment increases the risk of quality and food safety issues (especially for edible oils).

• Regulations: Different countries and regions may have strict regulations toward diverse kinds of oils with distinctive characteristics, they demand each kind of oil must have its dedicated production equipment.

• Brand trust & flavor carryover: Edible oils are odor-sensitive. A strongly aromatic prior batch can taint flavor and harm brand quality.

How to safely use one filling machine for multiple oils (recommended only within the same category).

• Replace the Filling Hose: Each time you change different type of oil for production, you must change the filling hose to prevent the residues from contaminating the product.
  NEOSTARPACK solution: Quick-release couplings and standardized spare kits to shorten changeover time.
  

• Thoroughly Cleaning: Before changing the oil for production, please make sure to wash and clean the filling machine’s pump and other parts that directly contact the oil thoroughly, as well as sanitize.
• Choose the Best Suited Filling Machine: Choose a filling machine that is suited to your requirements and with parameters to adjust to response to distinct kinds of oils.
• Maintain Regularly: Regularly maintain and upkeep your filling machines to ensure the consistency of their performance.
  NEOSTARPACK tip: Follow a preventive-maintenance calendar and keep a spare-parts list on hand.
  

Whether to share one oil filling machine depends on product properties, volume, cost, hygiene, and regulations. With the right safeguards (validated cleaning, dedicated wetted-part kits, recipe control), same-category oils can share a machine to increase utilization and reduce cost. For different categories (food-grade vs. industrial), use separate oil filling machines to uphold quality, safety, and compliance.
