Produktionsvorrichtung nach Anspruch 5, wobei die Behältnisse (1) mit Harnstoffagglomeraten durch Säcke gebildet sind, wobei das Greifelement (18) und die Schiene (16) angeordnet sind, um ein Behältnis (1) über den Behälter (42) der Auflösungsvorrichtung (26) zu bringen, die Öffnungseinheit (48) umfassend mindestens eine Diamantspitze (50), die mit Schneidmessern ausgestattet ist, die sich in einer Linie mit dem Behälter (42) erstrecken und angeordnet sind, um den Boden des Behältnisses (1) aufzureißen, sodass die Harnstoffagglomerate unter der Wirkung der Schwerkraft in den Behälter (42) fließen, nachdem der Boden des Behältnisses (1) aufgerissen wurde.
  7. Produktionsvorrichtung nach Anspruch 6, umfassend eine Rückgewinnungsstation (24) für Behältnisse (1), nachdem sie entleert worden sind, wobei das Greifelement (18) und die Schiene (16) angeordnet sind, um das Behältnis (1) zu der Rückgewinnungsstation bringen, nachdem fester Harnstoff aus dem Behältnis (1) in einen Behälter (42) abgegeben worden ist.
  8. Produktionsvorrichtung nach einem der Ansprüche 1 bis 7, wobei ein Behälter (46) zum Aufnehmen von festem Harnstoff teilweise in den Behälter (42) eingetaucht ist, wobei zumindest der eingetauchte Teil des Behälters (46) einen Korb (52) bildet, der in Fluidverbindung mit dem Innenvolumen des Behälters (42) ist, sodass der in dem Behälter (46) enthaltene Harnstoff in das demineralisierte Wasser in dem Behälter (42) eingetaucht ist.
  9. Produktionsvorrichtung nach einem der Ansprüche 1 bis 8, wobei der Behälter (42) ein Filterelement (47) umfasst, durch das fester Harnstoff in den Behälter (42) abgegeben wird, wobei das Filterelement (47) angeordnet ist, um feste Harnstoffagglomerate mit einem durchschnittlichen Durchmesser zurückzuhalten, der größer ist als ein vorbestimmter durchschnittlicher Durchmesser.
  10. Verfahren zur Herstellung einer wässrigen Harnstofflösung aus festem Harnstoff und entmineralisiertem Wasser mittels einer Produktionsvorrichtung nach einem der Ansprüche 1 bis 9, umfassend die folgenden Schritte:
    - Zuführen von festem Harnstoff aus der Speicherstation (2) in den Behälter (42) einer Auflösungsvorrichtung (26) und Abgeben des festen Harnstoffs in den Behälter (42) mittels der Fördervorrichtung (14), um einen Haufen festen Harnstoffs in dem Behälter (42) zu bilden,
    - Einspritzen von entmineralisiertem Wasser in den Behälter (42) unter den Haufen von festem Harnstoff, um den Harnstoff in dem entmineralisierten Wasser aufzulösen und die wässrige Harnstofflösung in dem Behälter (42) zu bilden,
    - Rückgewinnung der wässrigen Harnstofflösung aus dem Behälter (42).
  11. Herstellungsverfahren nach Anspruch 10, wobei das entmineralisierte Wasser mit einer Temperatur von im Wesentlichen zwischen 30 °C und 50 °C in den Behälter (42) eingespritzt wird.
  12. Herstellungsverfahren nach Anspruch 10 oder 11 mittels einer Vorrichtung nach Anspruch 2 oder 3, wobei die Fördervorrichtung (14) festen Harnstoff in den Behälter (42) einer der Auflösungsvorrichtungen (26) und anschließend in den Behälter (42) einer anderen Auflösungsvorrichtung (26) fördert und abgibt, wobei das Einspritzen von entmineralisiertem Wasser in die Behälter (42) beginnt, sobald sich in den Behältern (42) ein Haufen von festem Harnstoff gebildet hat, sodass der Beginn der Auflösung in einer Auflösungsvorrichtung (26) in Bezug auf den Beginn der Auflösung in einer anderen Auflösungsvorrichtung (26) zeitlich versetzt ist.
