Abstract

A continuous crystalliser preferably a vacuum crystalliser is shown having particular application to the sugar production and refining industry. The crystalliser comprises a vertically disposed cylindrical vessel 10 in which there are a series of sector shaped cells 38-52 defined by partitions 22-36 radially disposed about the axis of the vessel. Each cell is provided with an inlet eg 72 for molasses. A calandria is provided for heating the massecuite in each cell. Seed crystals are introduced into the massecuite in a first cell and the massecuite passes from cell to cell in a generally circular path through the vessel before passing through an outlet 78 in a cell adjacent the first cell but isolated therefrom. <IMAGE>
