ABSTRACT:
A device for cleaning surfaces which are soiled in the food industry with grease, starch or protein residues including: a housing body having a first inlet for feeding pressurized water; a propulsion jet positioned behind the inlet and in a direction of flow; a collection jet positioned behind the propulsion jet which is flow connected with a second inlet for feeding a chlorine-free alkaline foam cleaning agent and a third inlet for feeding a hydrogen peroxide solution; and a turbulence chamber into which an elongated jet body of the collection jet extends, the turbulence chamber fitted with a chamber inlet for feeding compressed air into the chamber such that a hydrogen peroxide foam is formed from a solution formed upon dosing an effective amount of the hydrogen peroxide solution into the chlorine-free alkaline foam cleaner at a maximum of 60 seconds prior to contact of the hydrogen peroxide foam with a surface to be cleaned, the turbulence chamber further having a chamber outlet through which the hydrogen peroxide foam leaves the chamber to contact the surface, the chamber inlet and the chamber outlet being fitted in a direction of flow ahead of an outlet orifice of the jet body.
