Definitions

  • the invention relates to a method and an installation for the extraction of juice from sugar beet for the industrial Sugar production, in which the previously washed Sugar beets are crushed and the crushed Beet mass separated into a solid and a liquid phase becomes.
  • Another problem is the protein present in the beet, which is broken down into amino acids in the process, in the heated extraction tower, which then make it necessary to control the pH by adding calcium hydroxide and to add the amino acids from the juice produced remove. This is because the amino acids change the pH value, are the cause of an inversion of the sucrose, thus lead to sugar losses and are a hindrance to sugar crystallization.
  • the amino acids generated in the process are bound with lime and the protein, which can be used as animal feed, is lost for further useful use.
  • the amino acids are spread with the lime on agricultural fields and have hardly any fertilizer value there, while the proteins contained in the beets are intrinsically valuable animal feed, which is lost in this process.
  • a third problem is with the beets in the process introduced bacteria that the beets during their storage do nothing because they are during the beet campaign prevailing outside temperatures are idle, the but at the temperatures of juice making by the Heat in the extraction tower become very active and not only eat sugar, but through their metabolic products make the juice sour what you add by adding of formalin has to compensate. This offer is over questionable for various reasons.
  • the invention avoids the disadvantages of the prior art Technology. It is the object of the invention with simple Means the process of juice production at continuous To design the procedure so that the Juice extraction from those who dominate the beet campaign Temperatures and therefore energetically essential runs cheaper and that the contained in the beet Protein can be fed to the animal diet can, and execute the process so that the with the Sugar beet bacteria introduced into the process cannot take effect.
  • the invention is that the crushing of Sugar beet at normal outside temperature during the Beet campaign takes place through a grinding process in which the cells are mechanically disrupted, but not completely be torn apart that the ground Beet mass at the same temperature in a separation stage, e.g. a centrifuge or press, in their liquid Part and their fixed part separates that one then the fixed portion of a further grinding process subjects, in which the cells are further unlocked and then the ground product at the same temperature in another separation device, e.g. one High performance centrifuge, again in a liquid and separates a fixed part that the cold obtained Juice quickly heated to about 90 ° for a short time, him sterilized with it, and then in a small amount Precipitants, e.g. an electrolyte, admixed and in this way the protein in the juice fails, that is removed from the juice in a separation stage, and that the juice obtained is now for further processing feeds while you have the precipitated protein added to the separated solid part.
  • a separation stage
  • This process can be operated continuously uses considerably less energy because only the one received Juice, but not solid matter and in the extraction tower added water must be heated, the The use of lime is eliminated, the use of chemicals has decreased, in particular the use is no longer applicable of formalin and sulfur dioxide. It will Protein as such is separated and can in the course of the process can be used as cattle feed by adding up to the low sugar residues otherwise only contain fiber Solid mass is mixed.
  • a system is used to carry out this method for the extraction of juice from sugar beet for sugar production with a beet washer, a beet shredder and a separator, which is characterized in that the beet crushing device a grinder or grater is through their grinding process, that at normal outside temperature during the beet campaign, the cells take place mechanically open minded, but not completely torn apart be that the beet grinder a separator, preferably a centrifuge or press, which is the crushed Beet mass in a liquid portion and a solid Part separates that a collection vessel for the liquid part or a pipeline is provided and that to the output of the separator for the fixed portion another shredder connected and this another separation device, preferably in the form of a centrifuge, downstream that a device for the short-term for the juice obtained High heating and a station for adding electrolyte and protein precipitation are downstream that this Station a separator for separating the precipitated Protein is downstream and that this facility a station to hand over the now pure juice downstream of
  • the resulting pectin can also be obtained by separating it from the process.
  • the drawing shows a block diagram of the system according to the invention: Washed sugar beets are fed via a conveyor belt 1 to a mill 2 or grater, the screw conveyor of which feeds the sugar beets to the grinder or grater. During this grinding process, the sugar beet cells are torn open and mechanically disrupted, but not completely destroyed.
  • the crushed beet mass is fed by means of a conveyor 3 to a first separation stage in the form of the centrifuge 4, from which the liquid product portion of juice is fed to the heat exchanger 7 serving as a heating device, in which the beet juice is heated to a temperature of approximately 90 ° C is heated in a short time.
  • the solid obtained in the first separation stage 4 is fed to a further mill 5 by means of a further conveyor and is ground in the latter in such a way that the cells are completely broken down.
  • the liquid part of this mass obtained is also fed to the heating device 7 after it has been separated from the solids content in the separation stage 6.
  • the heating device passes through a mixing device 8, in which the juice is supplied with a means for precipitating the protein by means of the feed pump 9.
  • the juice then flows into a calming vessel 10, where the protein flocculates.
  • the protein is separated in the downstream separator 11 and fed to the mixer 13 by means of the conveying device 12.
  • the juice running out of the separator 11 is then fed to further processing into sugar products, such as granulated sugar, liquid sugar, rock candy, etc.
