Facilities & Equipment: Wet Fractionation
Wet fractionation is a process in which a raw material is separated into the many components that form the whole, original material. Materials are processed in the presence of a solvent (water, ethanol, etc.). Processing technologies associated with wet fractionation include, but are not limited to, wet milling, distillation and centrifugation.

Colloid Mill (IKA MK 2000)
  • Materials can also be size reduced via a Colloid mill.
  • The material is processed in solution and yields a fine particle slurry. This is useful to minimize molecular damage and combines a size reduction technique with a separation step.
  • The colloid mill can also perform high-speed mixing of two different materials, such as protein and starch, in a solution. This will create micro-droplets or an emulsion. The finer the droplet, the more stable the final solution.
  • Solutions can be separated into dry and wet fractions using a vibratory sieve or centrifugation technology.
      • The vibratory sieve can be setup with 5 different screen sizes to separate particle based on size while removing free water (solvent).
      • Depending on solids content a decanting or disc centrifuge can also be used to separate solids from solvent.
      • The decanting centrifuge is used to process solutions with a solid content between 15% and 40% and the continuous (disc) centrifuge will process solutions with a solid content of 3% to 15%.
      • There is also a Solvent-compatible centrifuge that is safe to use solvents like ethanol, hexane, and methanol.
  • Solutions can also be dried to a powder using spray drying technology.
      • The solution is pumped into a very hot chamber, and water is immediately evaporated to yield a fine powder.
      • Spray drying offers a very flexible control over powder particle properties such as density, size, flow characteristics and moisture content.
  • Primarily projects have centered on starch and protein separation. There has also been work done in the areas of plant extracts and pulp waste separation.
