Abstract
A foaming apparatus and method according to which a mixture of gas and a liquid is introduced into a vessel at a predetermined velocity and passes through a passage in the vessel. The flow of the mixture through the passage is increased to increase the velocity of the mixture and cause corresponding shearing forces on the mixture to create a turbulance and form foam from the mixture. The restrictor can be moved in the passage to vary the amount of restriction and therefore the amount of the foam.
