A method for producing starch soft capsules comprises the following steps: preparing a mixture comprising starch, plasticizer and water, wherein more than 50 weight percent of the starch is present in the form of particles of granular starch; shaping the mixture to form a film in a shaping process; solidifying the mixture by increasing the temperature of the mixture during and/or after the shaping process by more than 5°C; and shaping the film to form a soft capsule. Soft capsules produced by this method have starch particles bonded to one another. A device for performing this method comprises a shaping device to enable shaping of the starch material to form a film, and a heating device to perform a heat treatment to destructure the starch during and/or after the shaping. It comprises a rotary die device.
L'invention concerne un procédé de production de capsules souples en amidon, qui comprend les étapes suivantes: production d'un mélange contenant de l'amidon, un plastifiant et de l'eau, dans lequel l'amidon se présente à plus de 50 %, en poids, sous la forme de particules d'amidon granulaire; opération de formage pour transformer le mélange en un film; solidification du mélange par élévation de sa température de plus de 5° C durant et/ou après l'opération de formage précédente; et opération de formage pour transformer le film en une capsule souple. Les capsules souples produites selon le procédé décrit présentent des particules d'amidon reliées entre elles. L'invention concerne également un dispositif pour la mise en oeuvre du procédé, qui comprend un appareil de formage permettant de transformer la matière de l'amidon en un film, ainsi qu'un appareil chauffant permettant de réaliser un traitement thermique qui vise à déstructurer l'amidon durant et/ou après l'opération de formage, et un appareil à matrice rotative.
