An example method for refining lactose may include washing lactose crystals in a lactose stream in an upstream wash stream including an upstream recirculating wash medium. Washed lactose crystals may be sieved from the upstream recirculating wash medium. The upstream recirculating wash medium may be recirculated back to the upstream wash stream. The washed lactose crystals may be discharged to a downstream wash stream comprising a downstream recirculating wash medium. An example system may include a plurality of refining stages. At least one refining stage may include a washing tank including a lactose crystal inlet and a crystal slurry outlet. The refining stage may include a pump to recirculate a wash stream from the crystal slurry outlet back to the washing tank at a predetermined flow rate. The refining stage includes a screen to separate washed lactose crystals from the wash stream.
A method comprising:
A system comprising a series of refining stages to refine lactose crystals in a countercurrent washing system, each stage of the series of refining stages comprising:
