ABSTRACT:
Disclosed is an apparatus useful in freeze concentration processes such as in the concentration of fruit juices. The apparatus performs both the recrystallization and ice-liquid separation steps of conventional freeze concentration systems. The apparatus comprises an inclined trough divided into zones by dams including, in sequence, a recrystallizer, an ice breakup, an ice drainage and an ice discharge zone. The apparatus is provided with a variable speed, rotating paddle auger with variably pitched paddles which advances, lifts, and breaks up the ice along the trough. The liquid concentrate is discharged through one or more discharge ports spaced along the bottom of the trough. The ice is discharged at the high end of the trough through a discharge chute.
