METHOD OF PREPARING FIRST CRYSTALLIZATION FILLMASS Russian patent published in 2000 - IPC

FIELD: sugar industry, more particularly preparation of first crystallization fillmass in sugar production. SUBSTANCE: method comprises crystals directly in condensed second crystallization sugar clarification containing 70-75 % of CB.. Growing of crystals is carried out in two steps. In first step syrup is pumped into vacuum pan from evaporation plant containing 58-65% of till 46-50% CB of crystals are attained in fillmass and in second step crystals are grown by pumping more third crystallization sugar clarification containing 56-65% of CB and fillmass is finally thickened till 92-92.5 % of CB. are attained in fillmass. After pumping more third crystallization sugar clarification to second growing step, second backflow of first crystallization fillmass is fed into vacuum pan in second growing step. EFFECT: shorter duration of boiling down of fillmass and reduced sugar losses. 2 cl, 2 ex
