Abstract

A high pressure press for treatment of substances such as food includes a floating piston in a pressure chamber, with seals. The floating piston has drainage system for collecting any pressure fluid that leaks past a seal of the floating piston. The drainage system includes a pressure reducer arranged inside the floating piston. The drainage system also includes an elastometic pad which is so arranged as to supply an underpressure to a space where pressure fluid leaking past a seal may collect. Collected pressure fluid is returned to the pressure chamber later in the cycle.
