Why Do Filling Machines Drip or Foam?

The Secret: Viscosity & Surface Tension Hozun's Perfect Solutions for 3 Fluid Types:

1. Aqueous / Watery Fluids

Ex: Toners, Alcohol

The Problem Low surface tension causes splashing or excessive foaming when filled at high speeds.

Hozun's Solution Diving Nozzle Technology: Using an elongated nozzle that dives to the bottom of the bottle and retracts synchronously as the liquid rises. This completely eliminates foam and splashing.

2. Oils / Medium Viscosity

Ex: Essential Oils, Serums

The Problem Strong cohesion causes a "hanging drop" on the nozzle tip after filling, dirtying the bottle and conveyor.

Hozun's Solution Anti-Drip Suck-Back: Servo motor control performs a "Vacuum Suck-back" motion, instantly retracting the residual liquid into the nozzle at the end of the cycle.

3. High Viscosity / Gels

Ex: Creams, Ointments

The Problem Poor flowability leads to slow feeding, clogging, or air pockets (cavitation) in the product.

Hozun's Solution Pressurized Feeding System: Equipped with a "Pressurized Hopper" or Piston-driven system to actively push material, ensuring smooth, high-speed filling even for thick gels.
