PARA EL PROCEDIMIENTO DE LA INVENCION PARA FRACCIONAR SUSTANCIAS CUYO CRISTALIZADO SE PEGA BASTANTE MAL EN LAS SUPERFICIES DE CRISTALIZACION (39) PRACTICAMENTE VERTICALES EN UN CRISTALIZADOR, EN PARTICULAR DE PARAFINAS, ACEITES, GRASAS Y CERAS, SE COLOCAN ENTRE LAS SUPERFICIES DE CRISTALIZACION (39) DE UN CRISTALIZADOR ESTRUCTURAS EN FORMA DE CRIBA, P. E. HOJAS AGUJEREADAS COLOCADAS EN ZIGZAG (31). EL CRISTALIZADO (51), QUE SE DISUELVE DURANTE LA FASE DE VAPOR EN LAS SUPERFICIES DE CRISTALIZACION (39), SE QUEDA EN BANDAS HORIZONTALES EN LA ZONA TRIANGULAR (41) SOBRE LA HOJA AGUJEREADA (31), SE QUEDA EN CONTACTO TERMICO CON LA SUPERFICIE DE CRISTALIZACION (39) Y GOTEA LA FASE LIQUIDA (55). EL AGUA MADRE (55) GOTEA, EN PARTE TAMBIEN ENTRE EL CRISTALIZADO (51) Y LA SUPERFICIE DE CRISTALIZACION (39), POR LO QUE MEDIANTE EL AGUA MADRE CALENTADA QUEDAN LIBRES LOS CANALES DE GOTEO. In a fractionated crystallisation process for substances whose crystalline products fail, during the sweating phase, to adhere adequately to a vertical or inclined surface, the novelty is that crystals (51) which are released from the crystallisation surface (39) are captured by a sieve-like supporting structure (29), while liquid passes through. Also claimed is an assembly in which a zigzag perforated metal panel (31) extends between the two vertical crystallisation surfaces (39).
