The invention relates to a centrifugal filtering method of paste juice in a
cane sugar factory. The centrifugal filtering method comprises the following steps: (1) transporting paste juice obtained ina
settling pond in a
settling manner to a number-I centrifugal
machine, separating the paste juice, transporting obtained filtered juice into a filtered juice box, and discharging obtained paste slaginto a paste
slag and water stirring tank; (2) adding water into the mud
slag and water stirring tank, and stirring; (3) transporting a material in the mud
slag and water stirring tank to a number-IIcentrifugal
machine, separating solids and liquid, transporting obtained filtered juice into a filter juice box, mixing the obtained filtered juice with the filtered juice in step (1), then transporting to a concentrating tank, and transporting obtained filtered paste to be used for producing
organic fertilizer or feed, wherein the
water content of the obtained filtered paste is less than 55 percent, and a
sugar degree of the filtered paste is less than 4.5 percent. By adopting the method, the solids and the liquid of the paste juice in the
cane sugar factory can be rapidly separated, the
treatment time of the materials is shortened, the production efficiency is increased, the
cane sugar loss of the filtered paste is reduced, the washing water amount is reduced, the energy is saved, the further comprehensive utilization of the filtered paste can be promoted, and the problems that the
water content of the filtered paste is high, the filtered paste is difficult to transport and the clean production of the environment is influenced can be solved.
