  • Patent number: 7618251
    Abstract: The invention relates to a device for processing an edible product in the form a viscous to pasty mass (1), especially an edible product based on a fat mass, such as chocolate, or based on water, such as ice cream. Said device comprises a dosing unit (2) for the dosed delivery of a specific volume of the mass (1) to shaping units (13). The movement of the displacement element (6) determining the dosage volume is performed via servo drive (9) while an inlet (4) and an outlet (5) are closed and opened via servo drive or pneumatic drive, respectively. Preferably, the displacement element is embodied as a combined lifting/rotating plunger (6) which can perform a linear movement for a suctioning lift and a dosing lift while being able to perform a rotary movement for opening and closing the inlet (4) and the outlet (5), i.e. a valve function.

  • Publication number: 20090035430
    Abstract: The invention relates to a method and a device for continuous production of a number of articles including at least two different types of articles from a pasty mass. The mass is introduced into a processor unit (4) by means of a supply unit (2), processed in the processor unit and transported further thereby, whereupon an adjunct is added by a metering unit (10) to the mass transported through the processor unit (4). The mixing of the adjunct introduced to the mass is carried out by a mixing unit (6) with mixing elements located downstream of the processor unit (4). The mass with provided adjunct is formed by a forming unit (S) into individual articles downstream of the mixing unit. According to the invention, the metering of the adjunct is carried out in a sequence of metering conditions with at least two different metering conditions, wherein the metering unit (10), for a given metering condition, introduces the adjunct to the mass at a given metering rate.
