ABSTRACT:
An apparatus for weighing a softened solid rapidly and precisely, wherein no excessive force is exerted on, and no shock is given to, the load cell. The apparatus has a simplified structure including 1/4 cylindrical weighing containers so that the apparatus is easy to disassemble and clean.
The inventive apparatus comprises a load cell for transmitting signals; a pair of weighing containers each having a cross-section of approximately 1/4 of a cylinder, arranged closely, and installed on the load cell rotatably around center axis of rotation; a scraping member installed closely to the inner surface of the weighing containers; and a driving unit, which is not connected to said load cell, for opening and closing the weighing containers by reversely rotating them around their axes. This apparatus for weighing a softened solid discharges the weighed substance as it is scraped from the sides of the containers by the scraping member.
