An electric retort oven will be used to dry a powdered propellant used in automotive airbags. The oven, manufactured by Baker Furnace, Brea, Calif., has a maximum temperature rating of 220°F (104°C).
The heating system utilizes a retort shell, so the propellant powder being processed in the chamber never makes direct contact with the heat source. The propellant can ignite if it comes in contact with high temperatures. Electric elements heat the stainless steel retort shell, which ultimately transfers heat to the interior of the retort chamber.
