  • Process for continuous crystallization of dextrose monohydrate
    Patent number: 4816079
    Abstract: A process for continuous dextrose-monohydrate crystallization whereby an evaporated concentrated liquor is mixed with a recirculated dilute phase to form a feeding liquor. At least a portion of this feeding liquor is fed through the shearing zone of a homogenizer. The sheared mother liquor is then fed to a vertical cooling-crystallizer to form a suspension. The suspension is separated into a concentrated phase and a dilute phase. The dilute phase separated from the suspension is employed as the dilute phase which is mixed with the evaporated concentrated liquor.
