Automatic Liquid Filling Machine for Cosmetics and Daily Chemicals (30-500ml)

Anti-Foaming Servo-Dosing and Nitrogen Blanketing for Premium Formulations

Product Overview

In the highly competitive cosmetic and daily chemical sectors, packaging machinery must deliver rapid changeovers while handling diverse fluid characteristics—from water-thin toners to highly viscous, prone-to-foaming dish soaps. The Lingyao LYGZZ Series Automatic Liquid Filling Machine is a heavy-duty, versatile linear platform engineered to process 30ml to 500ml PET, rigid plastic, and glass bottles.

Available in flexible configurations with 6, 8, 10, or 12 synchronized dosing heads, this platform achieves a steady, high-velocity output ranging from 2,000 to 4,000 Bottles Per Hour (BPH). By integrating intelligent anti-foaming nozzle architecture with optional nitrogen purging, it ensures flawless volumetric accuracy of ≤ ±0.5%, safeguarding both product presentation and raw material costs.

The Cause: Excessive Foaming and Oxidative Degradation

Processing diverse chemical and cosmetic formulations introduces severe mechanical friction points that standard liquid fillers fail to mitigate:

1. High-Speed Foaming: Daily chemicals containing surfactants (such as dish soaps, shampoos, and glass cleaners) naturally generate massive amounts of foam when dispensed at high speeds. This foam overflows the bottle neck, contaminating the threads, destroying the seal integrity, and halting the entire production line for clean-up.

2. Oxidation of Premium Cosmetics: High-value facial serums, active toners, and essential oils degrade rapidly when exposed to ambient oxygen. Trapping atmospheric air inside the PET bottle during the filling process severely compromises the formulation's shelf-life and efficacy.

3. Drip Contamination: Viscous cosmetic lotions frequently create a "tailing" effect at the end of a fill. Drips falling onto the external bottle surface ruin the premium retail presentation and require costly secondary wiping.

The Solution: Diving Nozzle Architecture and Inert Nitrogen Control

The Lingyao engineering team resolved these cross-industry bottlenecks through adaptable fluid dynamics and targeted atmospheric management.

To conquer foaming and drip contamination, the LYGZZ platform is equipped with servo-controlled Diving Nozzles with Vacuum Suck-Back. The nozzles descend to the bottom of the PET bottle and rise in perfect synchronization with the liquid level, effectively eliminating top-down splashing and foam generation. At the exact millisecond the fill concludes, a targeted vacuum retracts any residual droplets, leaving the bottle threads completely pristine for capping.

To protect high-value, sensitive cosmetics, the system can be configured with an integrated Nitrogen Purging Manifold. This mechanism injects a blanket of inert nitrogen into the bottle immediately prior to and during the dosing phase, aggressively displacing ambient oxygen and securing the molecular stability of premium skincare formulations.
