It is proposed to avoid an excessive formation of foam in the collection vessel of a protein separator by throttling the feed of air to a foam generator according to the foam generation rate in the said separator. The foam generation rate in the separator can be measured by the amount of phase water that is separated in a second separator, which is located between the foam collection vessel and a first separator, in which second separator the mixture generated by the foam generator is freed from liquid constituents.
