An Application of Small Hydrocyclones for Separating Yeast in the Brewing Industry
Keywords:Hydrocyclone, Yeast, Clarification, Solid Recovery, Solid-Liquid Separation
The separation performance of the dewatering (MZ) and the deoiling (HY1) hydrocyclones for separating yeast in the brewing industry were investigated. Their applications in the liquid clarification and yeast recovery processes were studied. The feed suspensions used in these experiments were taken from the fermentation tank in the brewing plant. For the liquid clarification application, both hydrocyclones demonstrated their ability to clarify liquid with up to 50% clarification efficiency. The clarification efficiency was found to increase with an increase in pressure drop. Only the dewatering hydrocyclone could provide solid classification for both studied suspensions. Additionally, a high operating pressure drop did not provide any benefit to the classification because yeasts have low time constant, which are turbulence sensitive.
