A High-Speed Nasal Saline Spray Bag-on-Valve (BOV) Filling Machine is a specialized piece of equipment used to fill nasal saline sprays that utilize bag-on-valve technology. This machine is designed to quickly, efficiently, and accurately fill and seal containers with saline solution, ensuring sterile, high-quality production for nasal sprays. It is particularly suited for large-scale manufacturing operations that require high output without compromising on precision.
Features
Bag-on-Valve Technology
Bag-on-valve systems consist of a valve attached to an aluminum or tinplate canister, with a collapsible bag inside that holds the saline solution. The product is separated from the propellant (usually compressed air or inert gas) by the bag.
This technology ensures that the saline is dispensed as a fine mist without coming into contact with the propellant, providing better hygiene and product longevity.
01
High-Speed Operation
The machine is built to process large volumes of nasal spray cans quickly, filling them at high speeds to meet the demands of mass production. This is essential for companies looking to increase production efficiency and reduce lead times.
High-speed machines typically have multiple filling heads, allowing multiple containers to be filled simultaneously.
02
Precision Filling
These machines are equipped with PLC control systems (Programmable Logic Controllers) and photoelectric sensors to ensure the exact volume of saline solution is filled into each bag inside the can.
Precise crimping and sealing technology prevent leaks and ensure that the bag is filled uniformly in every canister.
03
Vacuum Sealing and Crimping
Many high-speed nasal saline spray filling machines include a vacuum sealing function to remove air from the bag before filling, ensuring a longer shelf life and maintaining product sterility.
The crimping process ensures the valve is securely sealed to prevent leakage.
04
Automation and Control
Fully automated systems allow for minimal manual intervention, from feeding empty containers into the system to filling, sealing, and ejecting completed cans.
HMI (Human Machine Interface) panels are typically included, allowing operators to control and monitor the process with ease.
05
Compatibility with Different Can Sizes
These machines are often designed to handle various can sizes and shapes, making them versatile for different product lines or formulations.
06
Sterility and Hygiene
Designed specifically for pharmaceutical-grade production, the high-speed BOV filling machine ensures that the saline solution remains uncontaminated throughout the process. The product is never exposed to outside air, protecting it from contamination.
07
Filling Without Air Contact
Since the saline solution is contained inside the bag and the propellant is pressurized outside the bag, the product is dispensed only through pressure. This ensures that the saline is never in contact with the propellant, preserving its purity and sterility.
08
This Salt Water Nasal Spray Filling Equipment features twelve filling heads and four customizable cleaning heads, all operated by a PLC-controlled servo system that allows for automated and parameterized control. The cleaning heads can be tailored to meet specific customer requirements and are primarily designed to clean colored and easily solidifying materials. Utilizing pressurized industrial alcohol gas as the cleaning medium, the system effectively removes residual material from the valve core, preventing blockages and ensuring optimal performance.

Advantages
High Efficiency and Productivity
Fully automated, the system operates continuously with minimal human intervention, greatly enhancing production capacity.With several filling heads, it can process numerous containers simultaneously, cutting production time and boosting throughput.
01
Precise and Consistent Filling
The PLC system ensures accurate filling volumes and consistent operation, minimizing waste and enhancing quality control.Bag-on-Valve technology allows for precise filling without contact between the product and propellant, maintaining the purity of the saline solution.
02
Enhanced Product Shelf Life
This technology prevents contamination and oxidation by separating the saline solution from the propellant, extending the product's efficacy and shelf life.
03
Improved Hygiene and Sterility
The saline is filled into a sealed bag, preventing exposure to external air and maintaining sterility.
Clean-in-Place (CIP) System: The inclusion of a CIP system allows for automated cleaning, upholding hygiene standards and pharmaceutical regulations.
04
Versatility and Flexibility
Capable of handling various container sizes and shapes, the system adapts to different nasal spray products. Cleaning heads can be customized to meet specific product needs, effectively addressing difficult-to-clean materials.
