A method and apparatus for manufacturing small batches of solid paint is disclosed. The method includes a first step of providing a component of the solid paint as a liquid in a heated mixing container (15) that has a base (41) and sides (43) and includes a stirrer (23) for stirring the contents of the container. The next step of the method incudes controlling heating stirring of the contents of the container and progressively adding other components of the solid paint as solids to the container. The liquid acts as a heat transfer medium that transfers heat from the heated container and from the stirrer to the solids. The mix is heated to a temperature of the solid paint and forms a melt that is a uniform liquid. The final step in the method includes discharging the melt from the container and allowing the melt to cool and form the solid paint.
L'invention concerne un procédé et un appareil de fabrication de petites quantités de peinture solide. Ledit procédé comprend une première étape d'apport d'un composé de peinture solide, sous forme liquide dans un contenant de mélange chauffé (15), ce contenant présentant une base (41) et des côtés (43) et comprenant un agitateur (23) servant à agiter le contenu du contenant. L'étape suivante consiste à commander le brassage et le chauffage dudit contenu et à ajouter petit à petit d'autres composés de peinture solide, sous forme solide, dans le contenant. Le liquide agit comme un milieu de transfère thermique qui transfère la chaleur émanant du contenant chauffé et de l'agitateur, aux éléments solides. On fait chauffer le mélange à une température de peinture solide, ledit mélange formant une matière fondue qui est un liquide uniforme. L'étape finale dudit procédé consiste à décharger la matière fondue du contenant et à permettre à cette matière de refroidir et de former de la peinture solide.
