  • System for content analysis of comestible products using volumetric determination
    Patent number: 6829927
    Abstract: A system that performs content analysis on comestible products using volumetric determination with a single-chamber technique in a mass production environment. The content value determination system includes a conveyor system, a system for weighing the comestible products interposed along the path of the conveyor, a volumetric determination station that consists of a plurality of receiving chambers, and a control module. In this embodiment, each receiving chamber is equipped with a pressure sensor and a mechanical system for modifying the volume of the chamber. In addition, both the pressure sensors and the volume modification system of each receiving chamber are operably connected to the control module.
    Type: Grant
