Why the Right Essential Oil Bottle Filling Line Can Transform Production Efficiency

With the growing demand for essential oils and wellness products, many manufacturers are re-evaluating how they manage production. For those working with roller-ball bottles, manual filling can only go so far. Automation is now a requirement.
The Automatic Essential Oil Roller Ball Bottle Filling Line from ZONESUN is designed to meet this demand with an integrated system that handles filling, roller-ball placement, capping, and optional labeling, all in one streamlined process.

How the Machines are Designed for Efficiency

This essential oil bottle filling line is built with 316 stainless steel magnetic pumps. It can ensure filling cleanliness and accuracy, and avoid dripping. The filling and capping system utilizes a starwheel, enabling it to position each bottle gently and ensuring precise handling. A touchscreen PLC interface makes it convenient to switch settings for different product types. The roll-on essential oil filling line is capable of packing 25-30 bottles per minute, which is well-suited for growing brands and medium-scale operations.

What’s inside the essential oil bottle filling line

The machine combines several high-performance components:

  • Automated vibratory bowls for precise sorting and feeding of roller balls and caps
  • Non-drip nozzles ensure precise and mess-free liquid filling
  • Modifiable capping heads that adjust to fit different types of closures
  • An optional labeling unit to streamline and complete the packaging process
  • Space-saving compact rotary design that boosts production efficiency
