ABSTRACT:
Apparatus for the purification of evaporated sugar solution prior to cryslization in which the evaporated sugar solution is mechanically transformed in an in-line continuous process into a homogeneous creamy mixture of sugar solution and hydrophobic particles of non-sugars attached to micron size bubbles from which the sugar solution is separated. The apparatus through which the evaporated sugar solution is passed to so transform it for purification includes, in order, an open-top pump supply tank into which the solution is discharged to revolve about an outlet in the tank so as to form a vortex in the tank outlet drawing large bubbles of air into the solution, a standpipe connecting the tank outlet to the inlet of a centrifugal pump having a high speed impeller with straight radial blades, the standpipe and supply tank having such a relationship to the pump as to provide a pump suction static head only slightly greater than the vapor pressure of the evaporated sugar solution.
