Abstract
An air-based particle filtration system (10) having at least one fan (26) to filter particles (especially coffee grinds) based on weight. The particle filtration system (10) includes a chamber (44) and a hopper (12) for dispersing particles to be sorted into the chamber. The particle filtration system (10) has a controller driving the one or more fans (26) and a collector (36) for conforming particles and optionally a discard collector (38) for non-conforming particles.
Claims17
A particle filter apparatus, comprising
- a chamber comprising an inlet fan enclosure defining a first zone and an outlet fan enclosure defining a second zone adjacent to the first zone;
- an inlet fan operably connected to a first lateral side of the chamber and adjacent to the inlet fan enclosure to provide a flow of air into the chamber;
- an outlet fan operably connected to a second lateral side of the chamber opposite the first lateral side and adjacent to the outlet fan enclosure to exhaust air from the chamber;
- wherein the outlet fan enclosure overlaps and extends over the inlet fan enclosure and is separated by a gap to define an air inlet for the outlet fan;
- a first collector operably connected to bottom surface of the chamber, the first collector mounted under the first zone of the chamber to collect particles introduced into the first zone of the chamber;
- and
- a controller configured to drive the inlet and outlet fans to expel non-conforming particles introduced into the chamber from the first zone before arriving in the first collector.
A particle filter apparatus, comprising a chamber comprising a first enclosure defining a first zone and an outlet fan enclosure defining a second zone adjacent to the first zone;
- a hopper connected to a top surface of the chamber above the first zone;
- a first fan operably connected to a first lateral side of the chamber and adjacent to the outlet fan enclosure to exhaust air from the chamber;
- wherein the outlet fan enclosure overlaps and extends over the first enclosure and is separated by a gap to define an air inlet for the outlet fan;
- a first collector operably connected to bottom surface of the chamber, the first collector mounted under the first zone of the chamber to collect particles introduced into the chamber from the hopper;
- and
- a controller configured to drive the first fan to expel non-conforming particles introduced into the chamber from the hopper from the first zone before arriving in the first collector.
A particle filter apparatus, comprising a filtration chamber comprising an inlet fan enclosure defining a first zone and an outlet fan enclosure defining a second zone adjacent to the first zone;
- an inlet fan operably connected to a first lateral side of the chamber and adjacent to the inlet fan enclosure to provide a flow of air into the filtration chamber;
- an outlet fan operably connected to a second lateral side of the chamber opposite the first lateral side and adjacent to the outlet fan enclosure to exhaust air from the chamber;
- wherein the outlet fan enclosure overlaps and extends over the inlet fan enclosure and is separated by a gap to define an air inlet for the outlet fan;
- a hopper connected to a top surface of the chamber above the first zone;
- an air filter/collimator element disposed between the inlet fan and the chamber to promote laminar flow of air across the filtration chamber;
- a collector in fluid communication with a bottom of the chamber;
- and
- a control system to drive the one or more fans to expel non-conforming particles introduced into the chamber from the hopper before arriving in the collector.
