What is a Small Volume Liquid Filling Machine?
A small volume liquid filling machine is precision-engineered to dispense liquids ranging from 1ml to 100ml. These machines are essential for the cosmetic, essential oil, and biotech industries where products (like serums, perfumes, eye drops) are extremely high-value. The primary challenge in small volume filling is maintaining absolute precision (preventing overfilling) while handling issues like foaming, dripping, and viscosity changes.
Filling Technology Comparison
| Technology | Accuracy | Suitable Liquid | Limitation |
|---|---|---|---|
| Peristaltic Pump (Hozun Optimized) | ±1% | Low–medium viscosity, clean | Requires routine tube replacement |
| Piston Pump | ±0.5% | High viscosity, pastes | Cleaning is difficult, cross-contamination risk |
| Time-Pressure Filling | ±3% | Simple, cheap liquids | Low precision, sensitive to tank pressure |
Result: Hozun utilizes an optimized peristaltic pump combined with a proprietary suck-back valve to deliver the ultimate balance of ±1% precision and sanitary, easy-clean performance.
Why ±1% Accuracy Matters in Liquid Filling?
Especially critical for high-value liquids like serums, essential oils, and biotech reagents.
If your liquid costs $50/L
A 5% overfill = $2.5 lost per 100 bottles
→ That is a $25,000+ loss per 1M bottles.
Hozun helps you take that money back.
Why Standard Filling Machines Fail in Small Volumes?
Standard machines fail at small volumes (<100ml) because they cannot handle complex fluid dynamics. Here is how Hozun engineering solves it.
Dripping & Stringing
Viscous liquids cause tailing, wasting material and dirtying bottles.
Proprietary Anti-Drip Valve
Instantly cuts off liquid flow with negative pressure suck-back, ensuring a clean fill.
Viscosity Fluctuations
Temperature changes alter liquid density, making volumes inconsistent.
Servo-Driven Flow Control
Siemens / Mitsubishi PLC with precise servo motors dynamically adjust to maintain exact volume.
Bubbles & Foaming
Fast filling of chemical/protein liquids causes cavitation and overflows.
Submersible Bottom-Up Filling
Nozzles descend to the bottle base and rise with the liquid level, eliminating foam.
