Whirlwind type separation juice extracting method and equipment

The invention relates to an evaporation and sugar boiling method and equipment in a cane sugar factory, in particular to an entrainment separation juice extracting method and a device. The device consists of a plurality of whirlwind separators, wherein the whirlwind separators are uniformly distributed on the top of an evaporation tank, juice steam enters into air inlets of a whirlwind juice extracting device in the tangential line direction at high speed, under the effect of the centrifugal force, liquid drips in the juice steam are thrown to the device wall to be separated, and the liquid drips flow back into the tank through U-shaped pipes arranged at the bottom of the whirlwind separators, so the liquid drips are prevented for being converted into fog again because of the steam flow impact, clean juice steam is discharged to the top from center pipes of the whirlwind separators, and the goal of separation is reached. The sugar loss of the evaporation tank and a sugar boiling tank is avoided, and the invention has the juice extracting effects that the sugar content of dual effect condensing water is reduced from a range between 100 ppm and 150 ppm to a range between 25 ppm and 40 ppm, and the boiler soft water standard is reached.
