Abstract
A system for continuous casting of melt-cast products such as soaps, detergents and the like comprising: i) a substantially vertically disposable mold unit to favor solidification/casting of the melt cast composition during an upstream motion through the mold unit; ii) the mold unit operatively connected at it's lower end to a supply source of the melt-cast composition; iii) means for controlling the temperature of the melt in the mold unit to achieve the desired solidification and shaping during traverse of the melt from the bottom of the mold towards the top thereof, which is adapted to eject the formed cast product.
Claims11
A method for continuous casting of shaped fatty acid soap melt-cast compositions comprising:
- supplying a molten melt-cast fatty acid soap composition through a vertically disposable mould unit having temperature control means upstream from bottom, and allowing the melt to traverse upwards in the mould in a continuous casting process;
- controlling the mould temperature to thereby favour selective solidification and shaping of the melt into cast fatty acid soap product in the mould, which finally ejects from the top of the mould unit;
- and
- wherein the fatty acid and soap melt-cast composition cannot be readily stamped and shaped into tablets or bars following extrusion.
