Abstract

245,712. Kessler, F. Jan. 7, 1925, [Convention date]. Crystallizing.-Sugar syrup is passed through a series of horizontal crystallizing tanks to a centrifugal separator, the syrup being discharged from the bottom of each tank and fed to the bottom of the next. Stirrers, preferably formed of worms of opposite hand, work the syrup across the tanks in zig-zag courses. As shown, the syrup is fed from a container a to a tank d<1>, an agitating screw comprising opposite-handed sections f<1>, f<2> passing the syrup in the direction of the arrow, Fig. 2. The syrup is then fed successively to similar tanks d<2>, d<3>, d<4>, being finally passed to centrifugal separators by a pump h. A sampling faucet and a thermometer are fitted between each tank, and syrup or water may be fed to the tanks from storage tanks k. As shown in Fig. 3, the separators, which may be fitted between the tanks. comprise screw-conveyers n held clear of the walls of the containers p by wire spirals x the separated syrup being discharged from apertures o in the containerbottoms.
