Abstract
Foam dispensing systems and methods are disclosed. Such systems and methods may include a foamed material dispenser, a dynamic mixer having a gas input, a process material input, and a foamed material output. The foamed material output may be in fluid communication with the foamed material dispenser. A pump having an output may be in fluid communication with the process material input of the dynamic mixer, and a gas injection valve may be in fluid communication with the gas input of the dynamic mixer. A gas pressure regulator may be coupled between the pressurized gas supply and the gas injection valve, and a gas injection cycle timer may be operatively connected to the gas injection valve, the gas injection cycle timer causing the gas injection valve to pulse open and closed to send pulses of pressurized gas into the dynamic mixer through the gas input.
