Abstract: Continuous insect-based biowaste processing apparatus has a tubular drum; a drive for rotatably driving the drum; a shaftless screw conveyor fixedly connected to an inner surface of the drum; circumferentially spaced cantilevered blades that (a) are connected to the inner drum surface and (b) each longitudinally extends throughout the drum; and a mechanism for introducing a conglomerate portion that includes biowaste and insect larvae into the drum interior. The screw conveyor is subdivided into longitudinally spaced chambers for the introduced insect larvae, each of the chambers being defined by two adjacent flights of the screw conveyor and by the blades. The size of the insect larvae progressively increases within a more distally located rearing chamber. Two or more blades firmly hold and unify the conglomerate portion throughout its residing time within the drum interior while being distally conveyed.
