ABSTRACT:
An apparatus for chemical froth suppression in a fermenter comprises a froth sensor installed in the fermenter for tracing the froth and a vessel containing a chemical froth suppressor which is fed to the froth sensor and to the fermenter. The froth sensor comprises a hollow chamber accommodating a throttle and a nozzle. The chamber has a through opening with the walls having two ports congruent to and coaxial with the outlet orifice of the nozzle, through which passes a jet of the froth suppressor leaving the outlet orifice of the nozzle to fly past the through opening and to get into the chamber to be reflected from its concave wall for being removed into the vessel containing the chemical froth suppressor.
