La présente invention vise à simplifier un processus de développement de couleur pour du granit naturel utilisé comme matériau de construction, et de rationaliser le processus de développement de couleur de façon à permettre une production automatique, permettant ainsi une production efficace. La présente invention comprend : une unité de transport qui transporte du granit en ligne et permet un transport automatique de produits entre des procédés de développement de couleur pour permettre un développement de couleur individuel de granit ; une unité de coloration qui est conçue à une position arbitraire dans l'unité de transport de telle sorte que le processus de développement de couleur peut se dérouler dans un type en ligne ; et une unité de chauffage et une unité de refroidissement, qui sont disposées à la suite de l'unité de coloration sur un trajet de transport de l'unité de transport : une ligne de solution pour injecter une solution de chambre de pression, et une ligne de pression pour injecter et décharger une pression étant raccordées à l'unité de coloration ; des morceaux coupés de granit à l'état de pierre broyée étant individuellement fournis par l'ouverture et la fermeture d'une porte dans la chambre de pression, et après le remplissage d'un espace interne de la chambre de pression avec une solution, une pression étant appliquée de façon à développer une couleur dans le granit ; et l'unité de chauffage comportant un dispositif de chauffage monté sur l'unité de transport transportant le granit, le dispositif de chauffage ayant une lampe proche infrarouge montée sur les extrémités supérieure et inférieure d'un élément de transport de façon à permettre aux morceaux de granit d'être individuellement chauffés et séchés, puis refroidi par l'unité de refroidissement. Par conséquent, des couleurs peuvent être développées dans du granit naturel dans une ligne automatisée, améliorant ainsi la productivité et la qualité.
