Definitions

  • the present invention is a process for the batch production of large sugar crystals with crystal sizes over 5 mm, preferably over 8 mm by evaporation crystallization in a crystallization vessel, wherein between the growing sugar crystals and the supersaturated sugar solution, a relative movement is produced, which suspended the growing sugar crystals holds using a device as defined in the claims for carrying out this method.
  • Large sugar crystals over 5 mm, produced by special crystallization processes from concentrated, pure sugar solutions, are also called candy sugar.
  • sugar candy with crystal sizes over 5 mm, preferably even over 8 mm is still used.
  • Crystallization of sugar from supersaturated solutions produces, depending on the process conditions, more or less fine-grained products and, under certain other conditions, solid agglomerates of crystals of various sizes, which are mechanically coarsely granular. These products have the irregular shape of regrind and not the regular monklin sphenoidal form of sugar crystals, which is a sign of quality and purity to the consumer.
  • a process for the production of stringent candy in which a continuously supersaturated hot sucrose solution circulated outside the crystallization vessel is recirculated is, are added during the crystallization process at constant temperature seed crystals in cocurrent or countercurrent.
  • the sucrose crystals growing in the recycled sucrose solution are separated by sieving after reaching the desired crystal size. This method also leads to a relatively strong mechanical stress on the sugar crystals and thus not or only with very low yields to the desired large sugar crystals.
  • the object of the invention is therefore to provide a process for producing large sugar crystals having crystal sizes of more than 5 mm, preferably more than 8 mm, in which a relative movement is produced by evaporation crystallization in a crystallization vessel between the growing sugar crystals and the supersaturated sugar solution which keeps the growing sugar crystals in suspension, however, further measures are taken to control the crystallization process so as to minimize nucleation disturbances so that the incorporated sugar crystals surely reach the size otherwise achievable only in poor yields.
  • the crystallization vessel according to the invention has an overflow at the upper end into a collecting vessel with a larger diameter than the crystallization vessel, which already leads to a slowing down of the flow velocity. Through installations for flow calming, this leads to a sedimentation of newly formed fine grain, which can collect at the bottom of the collecting vessel and thus can no longer disturb the crystal growth of the large sugar crystals.
  • This is preferably used to increase the rate of production by increasing the rate of upward flow of the sugar solution as the size of the growing sugar crystals increases.
  • water In order to maintain the supersaturation in the solution as a driving force for the crystallization, water must be removed from the solution. In the process according to the invention, this is preferably done by evaporation under reduced pressure. The amount of heat consumed by the evaporation is supplied by appropriate heat in the sugar solution, with a small part is also available through the released heat of crystallization available.
  • the process according to the invention is capable of producing large sugar crystals with high yields, with crystal sizes of up to 25 mm.

  1. Procédé de production discontinue de gros cristaux de sucre présentant des tailles de cristaux supérieures à 5 mm, de préférence supérieures à 8 mm au moyen d'une cristallisation par évaporation dans un cristallisoir, dans lequel on crée un mouvement relatif entre les cristaux de sucre en cours de croissance et la solution de sucre sursaturée, lequel courant maintient en suspension les cristaux de sucre en cours de croissance, caractérisé en ce que le mouvement relatif est obtenu au moyen d'un courant dirigé vers le haut de la solution de sucre sans présence d'éléments mobiles mécaniques dans le cristallisoir, dans lequel la quantité d'eau évacuée par évaporation du système est maîtrisée grâce à l'apport de chaleur dans la solution de sucre et l'apport de chaleur est commandé de telle sorte que la sursaturation de la solution de sucre est conservée grâce à l'utilisation d'un dispositif composé de
    a) un cristallisoir vertical comprenant
    b) une admission inférieure pour la solution de sucre sursaturée,
    c) un fond perforé chauffable,
    d) un trop-plein situé dans un collecteur dont le diamètre est supérieur à celui du cristallisoir, lequel collecteur présente des chicanes permettant de ralentir le courant,
    e) une conduite de retour équipée d'une pompe pour renvoyer la solution de sucre du collecteur vers l'admission inférieure du cristallisoir,
    f) une conduite d'évacuation de la vapeur située dans la partie supérieure du collecteur,
    g) une ouverture d'entrée pour les germes cristallins située dans la partie supérieure du collecteur,
    h) une ouverture de sortie pour les cristaux de sucre finis située au-dessus du fond perforé,
    i) des dispositifs de mesure et de commande pour la température, l'apport de chaleur et la vitesse d'écoulement de la solution de sucre.
  2. Procédé selon la revendication 1, caractérisé en ce qu'un grain fin nouvellement formé est séparé à partir du courant de la solution de sucre sursaturée.
  3. Procédé selon la revendication 1 ou 2, caractérisé en ce que la vitesse du courant dirigé vers le haut de la solution de sucre est augmentée au fur et à mesure que la taille des cristaux de sucre augmente.
  4. Procédé selon l'une quelconque des revendications 1 à 3, caractérisé en ce que l'évaporation de l'eau est réalisée sous pression réduite.
