Regardless of the foam machine, to the basic principles of foam is blowing air into the solution. Various models of change is the introduction of gas in different ways, so results would be different.
 Bubble formation has two essential factors, one foaming agent solution, and second, air, and neither is dispensable. No foaming agent solution, the liquid film surrounding the gas will not form, there is no air bubbles. Without gas, a foaming agent single solution, foam can not be formed.
 Bubble formation in the system, the foaming agent solution is a dispersion medium, the gas is dispersed, the gas dispersed in a liquid to form bubbles, then bubbles formed by the numerous bubbles. In addition to blowing performance of this important factor, gas foaming agent solution is to introduce another important factor. While the gas into liquid, must be done by the foam machine, foam machine that uses a certain method of gas into liquid
