Organic waste processing device and method

An organic waste processing device comprising:

• an organic matter-receiving container having a bottom wall and a peripheral wall extending from the bottom wall and defining together an organic matter-receiving chamber;
• at least one grinding assembly at least partially contained in the organic matter-receiving chamber, each one of the at least one grinding assembly comprising:
• a drive shaft having an outer peripheral surface, the drive shaft being located centrally inside an ascending gas flow channel, the drive shaft being surrounded by a partition wall spaced-apart thereof with the ascending gas flow channel extending inbetween, a descending gas flow channel surrounding the ascending gas flow channel with the partition wall extending inbetween;
• and
• a rotatable blade assembly including a blade support sleeve mounted to said drive shaft and being engaged in rotation therewith, said blade support sleeve having a sleeve outer peripheral surface and the rotatable blade assembly further includes at least one blade mounted to the blade support sleeve and extending outwardly from said sleeve outer peripheral surface into the organic matter-receiving chamber;
• said drive shaft and said blade support sleeve being in fluid communication and configured to define at least one gas path to provide gas flow flowing from the descending gas flow channel of the drive shaft into said organic matter-receiving chamber;
• and
• a gas-propelling unit in gas communication with the ascending gas flow channel of said drive shaft;
• wherein the ascending gas flow channel and the descending gas flow channel are in fluid communication above an upper free end of the partition wall, and the partition wall comprises tubular shell extending upwardly from the bottom wall of the organic matter-receiving container and preventing organic matter contained in the organic matter-receiving chamber to enter into a gas-plenum chamber.

A method for grinding and drying waste organic matter, the method comprising the steps:

• adding waste organic matter into an organic matter-receiving chamber;
• and
• simultaneously grinding the waste organic matter by engaging in rotation at least one grinding assembly having at least one blade mounted thereon and drying the waste organic matter while it is grinded by blowing-gas into the organic matter-receiving chamber from a gas-plenum chamber through an ascending gas flow channel and a desc das flow channel of the at least one grinding assembly, a drive shaft of the at least one blade being located centrally inside re ascending gas flow channel, a partition wall surrounding the drive shaft and being spaced-apart er with the as flow channel extending inbetween, and the descending gas flow channel surrounding the ascending gas flow channel partition wall extending inbetween,
• wherein the ascending gas flow channel and the descending gas flow channel are in fluid communication above an upper free end of the partition wall, and the partition wall comprise tubular shell extending upwardly from bottom wall of the organic matter-receiving chamber and preventing the organic matter contained in the organic matter-receiving chamber to enter into the gas-plenum chamber.
