Contexte client et exigences du projet<\/h2>\n

En juin 2024, Square Technology a livr\u00e9 et mis en service l\u2019un des plus grands tunnels de cong\u00e9lation \u00e0 lit fluidis\u00e9 IQF (cong\u00e9lation rapide individuelle) de Chine pour Groupe Liqun<\/strong>, l\u2019un des plus grands conglom\u00e9rats chinois dans les domaines de la grande distribution, de la logistique commerciale et de l\u2019industrie agroalimentaire.<\/p>\n

Dans le cadre de l'expansion de sa division de transformation alimentaire \u00e0 Qingdao, le groupe Liqun avait besoin d'une ligne de cong\u00e9lation IQF en continu capable de traiter 7 tonnes par heure (7 000 kg\/h)<\/strong> de frites chaudes et pr\u00e9cuites sortant de la ligne de friture et de pr\u00e9-refroidissement sans s'agglutiner, sans \u00e9gouttement d'huile ni perte excessive d'humidit\u00e9.<\/p>\n

Proc\u00e9d\u00e9 de cong\u00e9lation IQF \u00e0 trois zones sur mesure<\/h2>\n

Pour faire face \u00e0 la chaleur sensible \u00e9lev\u00e9e et \u00e0 l\u2019humidit\u00e9 de surface des frites fra\u00eechement pr\u00e9cuites, Square Technology a mis au point un tunnel IQF \u00e0 lit fluidis\u00e9 sp\u00e9cialis\u00e9 \u00e0 trois zones :<\/p>\n

    \n
  1. Chambre de pr\u00e9-refroidissement :<\/strong>\n
      \n
    • Temp\u00e9rature :<\/strong> Contr\u00f4l\u00e9 au-dessus du point de cong\u00e9lation<\/li>\n
    • Fonction :<\/strong> \u00c9limine la vapeur de surface et la chaleur sensible avant la cong\u00e9lation de la cro\u00fbte<\/li>\n
    • Avantage :<\/strong> Emp\u00eache l'accumulation importante de givre sur les \u00e9vaporateurs des cong\u00e9lateurs \u00e0 basse temp\u00e9rature<\/li>\n<\/ul>\n<\/li>\n
    • Chambre de fluidisation pour le refroidissement de la cro\u00fbte :<\/strong>\n
        \n
      • M\u00e9canisme :<\/strong> Un flux d\u2019air froid vertical ascendant \u00e0 grande vitesse cr\u00e9e une v\u00e9ritable fluidisation<\/li>\n
      • Fonction :<\/strong> Forme rapidement une fine cro\u00fbte congel\u00e9e autour de chaque frite<\/li>\n
      • Avantage :<\/strong> S\u00e9pare imm\u00e9diatement les frites humides, ce qui emp\u00eache leur agglutination, leur adh\u00e9rence \u00e0 la bande transporteuse et la d\u00e9formation de leur forme<\/li>\n<\/ul>\n<\/li>\n
      • Chambre de surg\u00e9lation :<\/strong>\n
          \n
        • M\u00e9canisme :<\/strong> Circulation d'air \u00e9quilibr\u00e9e au niveau du deuxi\u00e8me \u00e9tage du convoyeur<\/li>\n
        • Fonction :<\/strong> R\u00e9duit la temp\u00e9rature \u00e0 c\u0153ur de mani\u00e8re uniforme jusqu\u2019\u00e0 \u221218 \u00b0C<\/li>\n
        • Avantage :<\/strong> Permet de conserver un ext\u00e9rieur croustillant et un int\u00e9rieur moelleux avec un minimum de d\u00e9shydratation<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n

              \n
            • 7 \u00e9vaporateurs ind\u00e9pendants log\u00e9s dans des compartiments isol\u00e9s<\/li>\n
            • Le d\u00e9givrage s\u00e9quentiel permet plus de 7 jours de production ininterrompue sans arr\u00eat de la cha\u00eene.<\/li>\n
            • Des volets d'isolation motoris\u00e9s emp\u00eachent la vapeur chaude issue du d\u00e9givrage de p\u00e9n\u00e9trer dans le tunnel de cong\u00e9lation<\/li>\n
            • Des bacs de drainage inclin\u00e9s et chauff\u00e9s emp\u00eachent la formation de glace sous les serpentins<\/li>\n<\/ul>\n<\/li>\n
