Aerosol is a state in which solid or liquid fine particles are spread in a gas. The size of fine particles varies from about 10 nm to about 1 mm. Things larger than this to some extents are called dust. Now a days we are using machines for filling aerosols, these may also call Aerosol filling equipment. There are different methods used now a days in industry.

Type of Methods for filling Aerosols:

Cold Filling

Pressure Filling

Compressed gas filling

Cold filling Method:

An equipment for cold filling consists of an insulated box chilled by copper tubing filled with dry ice or acetone.

In the cool filling method, there are two ways to fill spray:

The material and propellant are cooled separately in the first technique. This cold substance is poured into a chilled aerosol canister and then added to the aerosol vessel through valves. Seal the vessel and perform leak and strength tests. After that, the vessel will be caped, labelled, and packaged. X

Pressure Filling Method:

A measuring device that can measure the quantity of propellant or material deposited in a vessel at room temperature is used in the pressure fill method. Under the pressure created by a cylinder of nitrogen or compressed gas positioned on top of the valve, and by the pressure of the nitrogen, the material, and the propellant, the material and propellant are introduced individually or jointly via the input valve. Transfers to a vessel to check for internal pressure. External pressure is the same as the vessel. Return the vessel for testing after it has been sealed. Then cover, label, and wrap the vessel.

Filling using Compressed Gas:

A compressed gas propellant is used in the compressed gas filling process. To fill an aerosol vessel with compressed gas propellant, a pressure gauge in a big vessel is needed. The substance is put into the aerosol vessel and the assembly is in place before the compressed gas propellant is added. The air inside the vessel is then pulled in, and compressed air is delivered from the gas cylinder’s decompression valve.
