摘要

An apparatus for chemical froth suppression in a fermenter comprises a vessel containing a chemical froth suppressor and communicating via a pressure pipe with the fermenter. The pressure pipe has arranged at a preselected level with respect to the froth height a nozzle intended to form a jet of froth suppressor which enters a chamber through an inlet port thereof. This chamber is accommodated inside the fermenter substantially above the level of froth therein. The jet of froth suppressor is reflected from the concave wall of the chamber to be conveyed along the discharge pipe by a pneumatic or suction pump into the vessel containing the froth suppressor. The discharge pipe is provided at tne end thereof inside the vessel with a nozzle intended to form a jet of the chemical froth suppressor flowing along this discharge pipe into the vessel. A gas zone of the vessel containing the chemical froth suppressor is communicable with a gas zone of the fermenter by a pipe having provided therein a throttle means serving to maintain a required pressure inside the pressure pipe.
