4. The Puffing Process

The essence of puffing is to gelatinise the starch in wheat in a hot
pressure chamber and then suddenly release the pressure, so that the grain
expands to several times its original size.

The first step is to deliver a measured quantity of wheat into a pressure
chamber (known as `the gun') and heat it by high pressure steam to almost
200oC. This is achieved in less than a minute. The pressure is then
released, expanding the grains and shooting them into a large chamber
(referred to as `firing the gun').

I am not aware of any home puffing appliances.
