Aerosols are widely used in daily chemical, pharmaceutical, food, and industrial fields, and filling technology directly determines product safety and performance stability. Among them, the single chamber and dual chamber aerosol filling machines have become the core equipment for the industry's intelligent and refined transformation due to differences in technological routes.

1、 Technical principles and core differences

1. One yuan aerosol filling machine

Working principle: Pre mix the active ingredient with propellant (such as propane, compressed gas), fill it into a single chamber metal/plastic can, and release it uniformly through a valve.

Applicable scenarios: insecticides, air fresheners, and some cosmetics (such as hair gel) that require low mixing stability.

2. Binary aerosol filling machine

　　•Technological breakthrough: Adopting a dual chamber structure, separating the active substance from the propellant (or two immiscible components), and instantly mixing and spraying them out through a built-in channel during use.

　　•Core values:

• Avoid early reaction of ingredients and improve product shelf life (such as pharmaceutical spray containing protein);

• Realize stable atomization of high viscosity materials (lotion, gel).

2、 Comparison of Technical Advantages

1. Precision control

• The binary system is equipped with an independent metering pump with an error rate of ≤± 0.5%, which is suitable for high value-added products (such as insulin spray and skin care products);

The one yuan system has lower costs and is suitable for large-scale standardized production.

2. Security Enhancement

Binary filling reduces the contact between combustible propellants and their contents, thereby reducing storage and transportation risks;

• Inert gas displacement technology can avoid oxidation reaction (such as vitamin spray).

3. Environmental compatibility

The new generation of equipment supports the filling of low-carbon propellants such as hydrofluoroolefins (HFO) and nitrogen, helping to achieve the "dual carbon" goal;

The residual material recovery rate exceeds 95%, reducing raw material waste.

3、 Future Development Trends

1. Intelligent upgrade

Integrated AI visual inspection system, real-time detection of micro cracks and sealing defects in tank bodies (missed detection rate<0.001%);

Digital twin technology simulates the filling pressure curve and optimizes process parameters.

2. Material Innovation

Lightweight aluminum cans and renewable plastic composite packaging reduce carbon footprint;

Self repairing coating technology extends the corrosion resistance life of tank bodies.

3. Miniaturization and Customization

Portable nanoscale aerosols (such as personal disinfectant pens) have spurred the demand for micro filling lines;

Modular design supports quick switching of filling modes (one yuan/two yuan/multiple mixed).

　　Conclusion

From quick consumption of daily chemical products to biomedicine, the technology iteration of mono/binary aerosol filling machine is redefining the possibility of spray products. With the integration of new materials, the Internet of Things, and green chemistry, this field may enter a new era of "precision, safety, and sustainability" for the packaging industry.
