Dans ledit appareil, une plaque de prévention de concentration des boues est installée au niveau de la chambre pour former une surface de séparation dans l'espace entre un côté des vis d'une pluralité de vis et, de manière adjacente, l'autre côté des vis d'une pluralité de vis disposées dans l'espace intérieur pour le transfert des boues, formant ainsi une pluralité d'espaces de transfert de boues, une plaque réfléchissante est installée au niveau de la surface supérieure intérieure de la chambre pour refléter les micro-ondes émis vers l'arrière à partir d'une pluralité de magnétrons et les rayons infrarouges ou proches infrarouges émis vers l'arrière à partir d'une pluralité de lampes chauffantes, dans le sens des axes des vis à axes multiples, et un matériau thermo-isolant adhère à la surface extérieure d'une paroi formant un espace intérieur de la chambre pour améliorer le rendement thermique. La présente invention peut améliorer l'efficacité du séchage puisque les micro-ondes émis par les magnétrons et les rayons infrarouges ou proches infrarouges émis par les lampes chauffantes irradient directement les boues et les micro-ondes et les rayons infrarouges ou proches infrarouges réfléchis par la plaque réfléchissante irradient les boues grâce à l'installation de la plaque réfléchissante au niveau de la surface supérieure intérieure de la chambre au moyen d'un matériau métallique doté d'excellentes propriétés physiques telles que la résistance chimique, la résistance thermique, et analogues et doté d'une certaine brillance, peut sécher rapidement une grande quantité de boues en empêchant la perte de chaleur grâce à l'enveloppage de la périphérie de la chambre avec un matériau thermo-isolant en laine de verre, et maximise l'efficacité du séchage des boues en empêchant les boues d'être concentrées dans une direction si une boue très visqueuse circule dans la chambre afin d'éviter l'interférence du rayonnement des micro-ondes et de l'irradiation des rayons infrarouges ou proches infrarouges grâce à l'installation de la plaque de prévention de concentration des boues entre les vis à axes multiples, et permet ainsi le séchage rapide d'une grande quantité de boues.
