Filling stick deodorants is a challenging process. These products must stay liquid throughout the operation, yet they solidify quickly if temperatures drop even slightly. For a leading global personal care manufacturer, the challenge was clear: deliver high-speed hot-fill production without sacrificing dosing accuracy, hygiene, or efficiency, all while integrating smoothly into an existing high-volume line.
The challenge
Producing heat-sensitive deodorants involves several critical risks. The product must remain fluid from tank to container, while doses need to hit exact net weight targets even at full line speed. Valves and surfaces must stay clean to avoid leaks and contamination, and caps must be applied gently yet securely. Any hiccup could slow the line, generate waste, or compromise product quality—outcomes unacceptable in personal care manufacturing.
The solution
The customized hot-fill system delivers a complete answer. Fifteen temperature-controlled filling heads ensure precise dosing, while continuous recirculation keeps the product flowing and prevents solidification. The tankless, hygienic design minimizes waste and simplifies cleaning, and an external heated buffer tank maintains stable temperatures. A press-on capper paired with a puck-based container handling system secures closures gently but reliably. Integrated fully with the existing line, the system combines speed, hygiene, and precision without compromise.
To ensure optimal performance, efficiency, and reliability, the system is equipped with several advanced features designed specifically for heat-sensitive stick deodorants:
- High-speed operation up to 145 bpm for maximum throughput without sacrificing accuracy
- Precise fill accuracy to ensure consistent dosing and minimize waste
- Continuous product recirculation to prevent solidification in valves
- Hygienic, temperature-controlled system that maintains consistent product flow
- Press-on capping system for secure closure without damaging packaging
- Tankless filler design to reduce product retention and simplify cleaning
- Heated external buffer tank to guarantee thermal stability and smooth supply
- Puck-based handling system for stable and reliable container support
With precise dosing, advanced thermal control, and hygienic design, this hot-fill system adapts net weight technology to even the most heat-sensitive formulations, ensuring consistent, reliable, and high-speed production.
