Cleaning system for drinks preparation machine has mixer valve or pump connected to water supply and cleaning fluid supply and passes mixture through pipe in machine

摘要

The equipment has a housing (1) containing a control module (40) and a water supply via a pressure reduction valve (5). The water flow is divided and passes through two magnetic valves (21,31). The flow from the first valve (20) passes through an induction pump (70) which draws in cleaning fluid through a throttle valve (82) and a non return valve (81). The flow of cleaning fluid joins the water flow at a T-junction. The flow from the second magnetic valve (30) bypasses the mixer pump and goes to a T-junction (26) leading to a pipe (32) leading to a connector (60) for the pipe to be cleaned (61). The magnetic valves give a pulsating flow of fluid.
