Progressive freeze‐concentration was effectively applied to concentrate glucose in a model solution. Effective partition constants of the solute between the liquid and solid phases were determined experimentally. The constant was strongly dependent on the stirring rate at the ice front and the advance rate of the ice front. Increasing stirring rate and reduced rate of advance lowered the effective partition constant: an improvement in freeze concentration performance. A concentration polarization model was useful to describe the effects of the operating conditions on the effective partition constant.
