  • Patent number: 8585393
    Abstract: An edible product is made from a castable mass such as chocolate in a casting device that includes a container for receiving the castable mass and a metering unit. The metering unit has a nozzle block having nozzles facing away from the container and a valve block facing the container. The volume of a metering chamber between the nozzle block and the valve block can be changed by moving the nozzle block relative to the valve block. The casting method comprises steps of a) filling the mass container with the castable mass; b) drawing the mass into the metering chamber by enlarging the metering chamber volume by a first relative motion between the nozzle block and the valve block, and c) discharging the mass from the metering chamber by reducing the metering chamber volume by a second relative motion between the nozzle block and valve block.

  • Patent number: 8574476
    Abstract: A melt is made by heating a salt mixture containing a salt of sodium. The melt is set at a temperature higher than the liquidus temperature of the salt mixture, and poured into a mold for expendable core molding. The temperature when the melt is completely poured into the mold is set within a range not exceeding the liquidus temperature of the salt mixture by 30° C. An expendable salt core for casting is molded by solidifying the melt inside the mold. This makes it possible to more stably obtain the strength of a water-soluble expendable salt core for casting made of a salt cast product obtained by melting and molding salts of sodium and the like.

  • Patent number: 8562882
    Abstract: The invention relates to a method for the continuous production of semicrystalline polycondensate pellets. Said method comprises the following steps: producing a polycondensate material; shaping polycondensate pellets and solidifying the polycondensate melt in a liquid cooling medium, wherein the shaping of the pellets can be carried out prior to or after solidification; separating the pellets from the liquid cooling medium once the polycondensate pellets have cooled down to an average temperature that lies within the crystallization temperature range of the polycondensate; and crystallizing the pellets in a treatment chamber, the treatment gas being led in said treatment chamber in a countercurrent to the polycondensate pellets, the flow rate of the treatment gas being above the incipient fluidization point of the polycondensate pellets and the polycondensate pellets having a narrow dwell time spectrum in the treatment chamber.
