Product introduction of Vacuum Liquid Filling Machine
The vacuum liquid filling machine is a precision filling system designed for liquid products requiring accurate level control and clean filling. Built with 304 stainless steel for product-contact parts, it ensures hygienic and durable operation. The system is suitable for filling perfumes, essential oils, and other cosmetic liquids where overflow and fragrance loss must be minimized. It solves common issues such as inconsistent filling levels, spillage, and air contamination. This equipment is ideal for cosmetic manufacturers, fragrance brands, and small to medium production facilities seeking reliable and efficient liquid filling automation.


Working Principle
The machine operates based on a vacuum constant liquid level filling principle. When a bottle is placed under the nozzle, the bottle sensor detects it and activates the filling process. Liquid is drawn from the storage tank through a suction pipe under negative pressure and flows into the bottle. As the liquid reaches the preset level, excess liquid is automatically sucked back into the reservoir, ensuring uniform fill height. The vacuum system prevents overflow and reduces exposure to air, while the barometer allows real-time adjustment of air pressure for precise control.
