Clarification of Yeast Slurry


In brewing practice a need may exist to remove coagulated protein particles from yeast slurry prior to centrifugal concentration and re-use. Separating foreign particles from yeast slurry in producing de-bittered yeast for food purposes is also encountered. Kason Separators have been successfully installed on these applications.


Yeast slurry is continuously fed to a Kason Separator equipped with screens ranging from 42 to 200 mesh (wire opening 0.0138"to 0.0029") depending upon process clarification requirement. Oversize impurities total less than 1% of the feed by weight and capacity of a 48" diameter Separator will range from 120 down to 75 IGPM, depending upon the screen opening selected. Impurities are continuously discharged relatively free of yeast solids. Other models are available and a unit may be sized to meet the individual brewery's capacity requirement.


1. The Kason transmits no vibration to supporting structures and may be mounted portably for convenience in moving it to yeast tanks.

2. Polished stainless steel surfaces and absence of comers in this circular design results in ease of cleaning and rigid adherence to highest sanitary requirement.

3. A horizontal screen is used and the Kason's 3-dimensional motion discharges impurities relatively free of yeast contrasted to inclined screens that will discharge yeast with overflow solids, if the optimum angle is not maintained.


  • Single deck Kason.
  • Stainless steel construction at all points of material contact
  • Standard discharge spouts for both yeast and impurity.
  • Screen opening from 42 - 200 mesh to process requirement.
  • Models available for capability ranging from 10 - 175 IGPM.
