Jet mixing lance for foam spraying - esp. for butchery premises having two mixing nozzles for additive and air

摘要

Jet mixing lance to produce a stable foam has a pressurised water supply, a chemical additive supply and a compressed air supply. The chemical and the water are mixed in a section after jet mixing chamber, the water being ejected through a nozzle. The resulting mixture is then ejected through a nozzle into a chamber after which it combines with air to form a foam, the air stream entering normal to the jet axis. The nozzle can have circular or non-circular esp. elongated, cross section. The lance is used esp. for producing stable foams for cleaning purposes esp. in the meat preparation industry and in smoking cabinets.
