Definitions

  • the present invention relates to a flooded metering device used with any type of product, whether granulated or powdered.
  • Each feeder is suitable for a type of product, which may be powdered or granulated, such as cereals, sugar or powdery flours.
  • the Carousel Mug Dispenser is most commonly used for granular products. It comprises a funnel for receiving the product to be measured and packaged; below the funnel is a turntable provided with a plurality of containers, each of which, in time, is aligned at the outlet of said funnel as the platform is rotated, filling it with the product. Below the turntable is a base with an opening for the exit of the packaging product. As said platform rotates, one of its containers is aligned with the opening of said base, releasing the product from the container.
  • the control of the quantity to be packaged is made by the volume of the mugs that, after being filled, are moved under the rotation of the platform, until they find the exit positioned in the base of the doser, releasing all its contents for packing.
  • the single drawer mug dispenser is also used for granular products.
  • the measurement is made by filling a container that is positioned between a funnel filled with the material to be measured and an outlet of the packaging material.
  • the dispenser further comprises two floodgates, one upper and one lower than the container, which function as drawers that close or open the passage from the funnel to the container and from the container to the outlet.
  • the measurement is then made by the volume of the container, which is filled by keeping the lower gate closed and the upper gate open to receive the funnel material.
  • the upper gate is closed and then the lower one opens, freeing the material for packaging.
  • the volumetric screw feeder is more suitable for powder or flour products because it allows a finer adjustment of the measured quantity.
  • the second funnel further comprises an agitator that advances to the beginning of the dosing thread, facilitating the positioning of the product between its fillets.
  • the dosage is made as a function of the number of turns that the thread makes, the more turns, the greater the amount of product that advances to the exit of the tubular extension where it is released. For example, when choosing a quantity of product to package, you must adjust the number of turns or fraction of turns of the thread required for such volume to be dumped.
  • each of these dosers is suitable for one type of product, and it is not possible to use a single doser for different products, presented in powder or granules.
