Embodiment 1
[0019] (1) Recover the high-temperature steam condensate (3m³, 90°C) of the fluidized bed to the high-temperature condensate tank, use the circulation pump 1 to pump the liquid in the high-temperature condensate tank into the plate heat exchanger, and pass the circulation pump 2 to pump the heavy The heavy solidification mother liquor (3m³, 15°C) in the solidification mother liquor tank is put into the plate heat exchanger, and the heavy solidification mother liquor is preheated to 85°C in the plate heat exchanger (it takes 0.5h), and the heavy solidification mother liquor after heat exchange Beat back to the heavy knot mother liquor tank for standby;
[0020] (2) Pour 3200kg of raw sugar and 3m³ preheated re-condensation mother liquor into the re-consolidation cooking kettle, turn on the re-consolidation circulation pump and steam (steam pressure 1.5kg), and carry out the re-consolidation cooking operation. After 2.2 hours, the temperature of the re-condensed cooking material...
