Foaming systems for food processing
The use of foaming agents increases the time element of the cleaning mix. Foams allow the cleaning chemicals to cling longer to the surfaces being treated and so allow more time for them to work. This means that less chemicals can be used reducing both costs and runoff.
A variety of foaming systems are available. They can be airless or air-assisted. The addition of compressed air to a foaming system allows for lighter more stable foams to be generated that will cling for longer periods. Airless foams will tend to be 'wetter' but nonetheless still give vastly superior dwell times when compared to basic liquid washdown regimes.
Foaming units can be wall-mounted, trolly mounted or the foaming agent can be mixed directly at the gun.
