Abstract

Ujawniono sposób wytwarzania dużych kryształów cukru o wielkości powyżej 5 mm, zwłaszcza powyżej 8 mm, poprzez krystalizację z odparowaniem w zbiorniku krystalizacyjnym, przy czym między narastającymi kryształami cukru i przesyconym roztworem cukru wytwarza się ruch względny, który utrzymuje kryształy cukru w stanie zawieszenia, przy czym ruch względny wytwarza się bez udziału ruchomych mechanicznych części, przez doprowadzany z zewnątrz strumień roztworu cukru, zaś odparowanie z systemu odprowadzanej wody jest sterowane przez doprowadzenie ciepła do roztworu cukru, przy czym doprowadzenie ciepła jest tak sterowane, że roztwór cukru jest utrzymywany jako przesycony. Wynalazek obejmuje także urządzenie do stosowania tego sposobu.A method is disclosed for producing large sugar crystals having a size above 5 mm, especially above 8 mm, by evaporative crystallization in a crystallization tank, wherein a relative motion is produced between the growing sugar crystals and the supersaturated sugar solution which keeps the sugar crystals in suspension, wherein the relative motion is produced without the use of moving mechanical parts by an externally supplied stream of sugar solution, and evaporation from the discharge water system is controlled by applying heat to the sugar solution, the heat input being controlled such that the sugar solution is kept supersaturated. The invention also includes a device for applying this method.
