<p>The liquid containing active ingredients is pumped by a piston pump to a pressurised reservoir is a non-return valve. This is connected via a mixer valve through a diffuser into a mixing cylinder, containing baffle plates, in which saturation occurs. The saturated liquid is led to a filling device by pumping and the overpressure in the filling device is regulated by a recycle valve so to be infinitely variable. The filling device also has a bleed valve allowing a purge of the apparatus and a quick changeover. of liquids handled.</p> |
