Drying apparatuses, dust separation devices, crushing devices, organic waste disposal systems, and operating methods

An organic waste disposal system, comprising:

• a crushing device for separating organic waste into organic solid residue and a free liquid;
• and
• a drying apparatus connected to the crushing device, comprising:
• a drying chamber having a substantially circular or polygonal cross-section, and including:
• a waste inlet connected to a residue outlet of the crushing device for introducing an intake airflow and the organic solid residue into the drying chamber, the waste inlet positioned radially offset from an axis of the substantially circular or polygonal cross section such that the organic solid residue cyclonically rotates around the axis;
• a flow outlet for discharging a first airflow, positioned on or adjacent to the axis of the substantially circular or polygonal cross-section;
• and
• a discharge outlet for discharging dried organic waste, and radially offset from the axis of the substantially circular or polygonal cross-section, wherein a discharge channel directly coupled to the discharge outlet is oriented to extend in a direction substantially opposite to gravity;
• an air pump fluidly coupled to the flow outlet and configured to generate a negative pressure in the drying chamber, thereby causing the intake airflow and the organic solid residue to enter the drying chamber through the waste inlet and to maintain a cyclonic rotational movement of the organic solid residue within the drying chamber, while the first airflow is drawn out of the drying chamber through the flow outlet;
• and
• a microwave inlet for coupling to a microwave generating device, the microwave inlet providing a microwave pathway into the drying chamber for microwaves to contact and dry the organic solid residue cyclonically rotating therein.

A method for disposing organic waste, comprising:

• crushing and dehydrating the organic waste to form organic solid residue and liquid;
• cyclonically rotating the organic solid residue in the drying chamber of a drying apparatus comprising:
• a drying chamber having a substantially circular or polygonal cross-section, and including:
• a waste inlet for introducing an intake airflow and the organic solid residue into the drying chamber, the waste inlet positioned radially offset from an axis of the substantially circular or polygonal cross section such that the organic solid residue cyclonically rotates around the axis;
• a flow outlet for discharging a first airflow, positioned on or adjacent to the axis of the substantially circular or polygonal cross-section;
• and
• a discharge outlet for discharging dried organic waste, and radially offset from the axis of the substantially circular or polygonal cross-section, wherein a discharge channel directly coupled to the discharge outlet is oriented to extend in a direction substantially opposite to gravity;
• an air pump fluidly coupled to the flow outlet and configured to generate a negative pressure in the drying chamber, thereby causing the intake airflow and the organic solid residue to enter the drying chamber through the waste inlet and to maintain a cyclonic rotational movement of the organic solid residue within the drying chamber, while the first airflow is drawn out of the drying chamber through the flow outlet;
• and
• a microwave inlet for coupling to a microwave generating device, the microwave inlet providing a microwave pathway into the drying chamber for microwaves to contact and dry the organic solid residue cyclonically rotating therein;
• and
• directing microwaves to the cyclonically rotating the organic solid residue thereby producing dried organic residue.
