抄録

The mechanism of solute incorporation into an ice-layer in freeze concentration with ice-lining was studied by changing the impeller speed N and the difference between the brine temperature and the freezing point of the feed solution ΔT in 10 kg/m³ CCNa solution. The effect of N on the apparent partition coefficient of the solute K, is more serious than that of ΔT. The growth rate of the ice layer is 10^-710^-6 m/s under the condition of ΔT = 2.87.9°C and N = 20400 min^-1. The growth rate had a little effect on solute incorporation into the ice-layer. K values depended on the surface condition of the ice layer, which is effected by the mixing speed of the impeller. The ice layer formed at low mixing speed has a complex rough shape, and has much solute because of adhesion to a large surface area. Therefore, it is recommended that freeze concentration is performed by making an ice layer with smooth surface at high mixing speed.
