Definitions

  • the first step is to open the juice containing cells so that the extractable juice of cane be readily available for leaching or displacement.
  • 80 to 84 % of the extractable juice % cane (1) can be extracted by dry pressure in a mill. Sugar (Pol) extraction is from 60 to 80 %. For higher extraction, imbibition have to be resorted to. The aim of imbibition is to dilute the extractable juice of cane before the final juice extraction by pressure.
  • Extractable juice % cane 100-1.25 F If fiber % cane (F) is 16 then extractable juice % cane is 80 %
  • n° 1 mill bagasse is processed in a counter-current multistage dilution process. In each stage, two separate operations take place :
  • stage efficiency in diffusion is not any better than in milling.
  • the number of stages used which should be between 4 and 7 (depending on the imbibition rate) assuming 100 % efficient mixing, is between 15 to 18 (so that the stage efficiency is between 4/15 (26.7 %) to 7/18 (38.9 %)
  • the bulk density may vary from 250 to 350 Kg/cubic meter.
  • the average bulk density (counted on cane only) is between 500 to 600 Kg cubic meter. Which means that the average apparent volume occupied by one ton of cane must be between 1.67 to 2 cubic meters. Deducting the no void volume of cane, this leaves a void volume of between 0.78 to 1.11 cubic meter. The filling of this void volume of with 1.05 density juice will require 819 Kg to 1.655 Kg of juice.
  • the object of the present patent is to make the cane juice displacement process efficient by resorting to "meichage" in a continuous cane juice extraction equipment.
  • the target of 4 brix of juice in the final megasse (corresponding to a Pol extraction rate of 98 %, assuming a final dewatering giving a juice content of the bagasse of 0.64 F) is reached in three stages.
  • the meichage juice (14 F) will be supplied by the drainage juice with a mixed brix of 5.7
  • the dewatering mill juice (5.36 F) will be used as displacement juice, followed by imbibition water 2 F
  • the brix of the displaced juice (7.36 F) will be 6.22
  • a conventional horizontal drag type conveyor can be used to move the prepared cane delivered by the shredder to the dewatering mill.
  • the speed of the conveyor (approximately 20 meter/minute) is set according to the cane flow so that a layer of about 0,3 meter is moved along, over the perforated bottom (1) of the conveyor.
  • the conveyor has a closed double bottom (2) with compartments and piping to comply with the flow diagram in each of the 3 stages.
  • the megasse is discharged from the last section of the displacement conveyor into the chute (9) feeding the preextractor (PE)
  • the preextractor consists in conventional 4 roller mill from which the trash plate and the delivery roll have been removed. It is a tilted 3 roller mill set to remove half of the juice content (6 F) of the megasse.
  • the bagasse coming out of the preextractor is conveyed by a closed chute (Meinecke chute) (C) to the bottom of the conventional bagasse elevator (E) feeding the (Donelly) chute of the final dewatering mill (DWM) which is a conventional 4 roller mill receiving the usual juice content (3 F) consisting, in a conventional milling tandem of the juice content (IF) of the second last mill bagasse and of the imbibition water (2 F) added in front of the last mill.
  • C closed chute
  • E bagasse elevator
  • DWM final dewatering mill
  • the dewatering juice coming from the preextractor (3 F) and the final dewatering mill (2.36 F) are pumped at the rate of 5.36 F to the displacement juice trough (5) of the third stage by pump (10).
  • displacement juice from the third stage is pumped from tank 8 by pump (10) to the displacement juice trough (5) of the second stage.
  • Displacement juice for n° 1 stage is pumped from 2nd stage tank (8) by pump (10) to N° 1 stage displacement juice trough.
  • the juice extracted from the plant overflows from receiving tank (8) of the first stage into a pump feed tank (11) from which it is pumped at the rate of 6.36 F as mixed juice to the process.
  • the level of juice in the receiving tank (8) in each stage must be at least 2 meters, and preferably between 3 to 4 meters lower than the level of juice in the conveyor (top of the cane bed).
  • the conventional drag type conveyor can be used for juice extraction by the displacement process, only up to a capacity of 5/6000 tons of cane per day, because of the following limitations :
  • the displacement process can only be performed efficiently when the juice content of the megasse is at least 20 times the fiber content of the cane - which means that the fiber content of the megasse must be less than 1/20 or 5 %.
  • megasse has the hydrodynamic characteristics of a liquid.
