What is An Aerosol Filling Machine
Aerosol filling machine is a professional equipment used to fill aerosol products into aerosol cans. It can automatically complete a series of processes such as liquid filling, gas pressurization, valve assembly, etc., to achieve mass production of aerosol products.
Widely used in pharmaceutical, cosmetic, food and industrial applications, aerosol filling machines are capable of handling a wide range of product forms from low-viscosity solutions to high-viscosity emulsions. There are various types of aerosol filling machines that are based on different criteria. One of the most common classifications is differentiated by the degree of automation.
Automatic aerosol filling machine
Introduction of Automatic Aerosol Filling Machine
Fully automatic aerosol filling machines are highly efficient production equipment integrated with advanced automation technology, representing the cutting-edge level in the field of aerosol filling. Such equipment adopts a closed-loop control system, integrating high-precision servo drive technology and real-time data acquisition and analysis capabilities, which can realize full unmanned operation. The core components include multi-head filling valve sets, intelligent dosing systems and online quality control units. The filling accuracy is usually up to ±1% and the production speed can be as high as 130-150 cans/minute. Fully automated aerosol filling machines are generally modular in design and equipped with a quick changeover system that allows switching between different product sizes within 15-30 minutes. To meet GMP requirements, the machines often incorporate a CIP/SIP system to ensure the sterility of the filling environment. Advanced models are also equipped with artificial intelligence-assisted visual inspection systems for real-time monitoring of the filling process and the quality of the finished product.
Working Principle
Empty can transportation
Empty aerosol cans are automatically fed into the filling machine via a conveyor belt. Sensors detect the position of the empty cans to ensure accurate positioning.
Filling preparation
The filling valve is cleaned and sterilized to ensure hygiene and safety. PLC control system adjusts the opening and closing time of the filling valve and the filling pressure according to the preset parameters.
Quantitative filling
The filling valve injects the product contents into the aerosol can according to the set time and pressure. The high-precision liquid level sensor monitors the filling volume in real time to ensure that the content of each can is consistent.
Valve Installation
After filling, an automated assembly station precisely installs the valve onto the aerosol can. A rotary tightening device seals the valve securely to prevent leakage of the contents.
Assembly of accessories
Accessories such as spray nozzles and protective caps are automatically assembled onto the aerosol cans by a dedicated station. A robotic arm ensures that the accessories are precisely positioned.
Finished product output
The finished aerosol cans are sent out of the filling machine on a conveyor belt after quality inspection. Non-conforming products are automatically rejected to ensure the high quality of the products leaving the factory.
Semi-automatic aerosol filling machine
Definition of Semi-Automatic Filling Machine
Semi-automatic aerosol filling machines are mid-range production equipment that combines manual operation and mechanical automation for small to medium scale production and multi-species small batch production scenarios. These machines utilize a semi-open-loop control system that integrates precise metering technology and basic data logging functions, requiring operator involvement in some parts of the production process. The core components include single- or dual-head filling valves, manually adjustable dosing systems and off-line quality inspection units. Filling accuracies of ±1% are typical, and production speeds typically range from 10-20 cans/minute.
Working Principle
Manual loading
The operator puts the empty aerosol cans into the filling platform. Manually adjust the position of the can opening and align the filling valve.
Filling control
The operator sets the filling volume and filling time through the control panel. The semi-automatic control system adjusts the opening and duration of the filling valve according to the set values.
Foot switch
The operator steps on the foot switch to start the filling process. The filling valve injects the contents into the aerosol can according to the set time and flow rate.
Manual closing of the valve
After the filling is completed, the operator releases the foot switch to stop the filling. The valve is closed manually to prevent the contents from dripping.
Manual assembly
The operator manually tightens the valve and installs accessories such as nozzles and protective caps. Visual inspection of each assembly step to ensure product quality.
Finished product transfer
Filled aerosol cans are manually transferred by the operator to the next process. Non-conforming products can be rejected at any time, reducing the defective rate.
