Pressurized container – suitable for compressed, liquefied or dissolved gas fitted with a device that, after its actuation, produces a controlled spontaneous release of the contents at atmospheric pressure and room temperature.
Aerosol Filling Methods
This method has a fill accuracy typically + or – ½ mL and capable of filling many different product types and viscosities up to 50,000 centipoise.
Nitrous oxide and carbon dioxide are used as propellants to deliver food products.
Method 1 – Gas is mixed with the product in saturation towers until blended properly. The product and CO2 are filled into the aerosol container as one.
Method 2 – Gas is injected through the aerosol valve stem using time over high pressure. Sometime the CO2 is heated to aid in saturation. Shaking is common during gassing.
Method 3 - CO2 is injected under the aerosol valve cup using time over pressure. Restricted valve lift helps to create turbulence for saturation.
