Definitions

  • the crystals are mixed with lean second jet sewer. This operation makes it possible to increase the purity of the crystals by dissolving the film of impurities which covers them.
  • This mixture is then drained in the centrifugal wringer 18 where the refined crystals, discharged at B, are separated from the refining sewer which is directed towards the pasting mixer 20.
  • the refining sewer which contains already small crystals having passed through the sieve of the wringer 18 are mixed with. sugar crystals from the dedusting cyclones 24 of the sugar drying plant of the factory.
  • the mixture formed in the mixer 20 is sent to a mixer 22 then to the first compartment of the device of crystallization 10 where it is used as seed magma.
  • the mixer 22 serves as a buffer capacity to absorb irregularities in the operation of the workshop.
  • the refining sewer C is heated in an exchanger 30 by means of steam taken from one of the last effects of the juice concentration installation.
  • the heated sewer is introduced into a capacity 32 where part of its water is evaporated by expansion, this capacity being placed under vacuum, for example by connecting it to the calender of the crystallization apparatus by a pipe 33.
  • This evaporation allows to maintain the sewer in a supersaturation state despite the rise in temperature.
  • Its concentration is maintained at a set value by a regulator 37 acting on a valve 38 placed on the arrival of heating steam from the exchanger 30 as a function of the temperature of the sewer measured by a sensor 39.
  • the magma produced in the mixer 20 is introduced into a tank 36 from which it is drawn off by a pump 42 which sends it to the first compartment of the crystallization apparatus.
  • the refining sewer constituting the mother liquor of the magma formed in the mixer 20 is heated, demulsified and concentrated to keep it in a supersaturation state.
  • the treatment also makes it possible to lighten the evaporation and crystallization work of the continuous-running crystallization apparatus using magma.
  • the residence time of the magma in the apparatus 50 can be of the order of 2 to 3 hours.
