A comminuting device for solids-conducting liquids includes a housing with an inlet opening, an outlet opening and a housing interior space which extends from the inlet opening to the outlet opening. A first comminuting shaft arranged for rotation about a first comminuting shaft axis, and a second comminuting shaft arranged for rotation about a second comminuting shaft axis each extend through the housing interior space. A first screen device is arranged in the housing interior space adjacently with respect to the first comminuting shaft with a first screen wall having a multiplicity of slots. A first evacuating device with a plurality of evacuating elements which can be moved along a movement path relative to the screen wall extends through the plurality of slots on at least one portion of the movement path.

A food waste disposer includes: a housing; a grinding case positioned inside the housing and configured to be separable from inside of the housing to outside of the housing and treat food waste; a rotating grinder configured to treat the food waste by rotating inside the grinding case and rotatably coupled with respect to a bottom surface of the grinding case; a grinder rotating shaft inserted in the rotating grinder and configured to rotate together with the rotating grinder; and a driver positioned below the grinding case and configured to provide rotation power of the rotating grinder, wherein the driver includes: a driving motor configured to generate power; a shaft driving gear configured to rotate by receiving power of the driving motor; and a connecting shaft configured to be rotatable within a range of a first angle with respect to the shaft driving gear, wherein one end of the connecting shaft is inserted in the grinder rotating shaft and another end of the connecting shaft is inserted in the shaft driving gear to transfer power from the shaft driving gear to the grinder rotating shaft.

A food waste disposer includes: a housing; a grinding case positioned inside the housing, configured to grind food waste, and separable from the housing, wherein a discharge hole is formed in a bottom of the grinding case; a valve assembly coupled to the grinding case below the discharge hole and configured to open or close the discharge hole, the valve assembly protruding below the grinding case; a storage case positioned below the grinding case and configured to store the grinded food waste from the grinding case; a transfer tube positioned between the valve assembly and the storage case and configured to transfer the grinded food waste from the grinding case to the storage case; and a connector coupled to the transfer tube, wherein a shape of the connector is deformable upon the valve assembly resting on the connector.
