LARGE PRODUCTION DEVICE OF A FLY LARVA

A fly larva mass production apparatus designed to raise seed fly larvae with organic waste on a multi-stage flat belt conveyor, to separate mature fly larvae from fly larva's excrement on a mesh belt conveyor and collecting fly larvae on a collecting belt conveyor is provided. The apparatus kills fly larvae mixed in fly larva's excrement and reutilizes waste organic material such as livestock excretions and food waste. The fly larva mass production apparatus contains: a fly larva raising part(100) comprising a flat belt conveyor(101 to 104); an inlet part(200) for supplying organic waste contained in a hopper(220) to an inlet(210) on one side of the flat belt conveyor; and an automatic organic waste-leveling device(310). The apparatus is characterized in that it has a seed larva mixture supply line(400) at the top of the flat belt conveyor to supply interior conveying material to the organic waste, a mesh belt conveyor(500) at the bottom and a collecting belt conveyor(600) for collecting larvae of flies and a small amount of fly larva's excrement. The seed fly larva mixture contains rice bran, barnyard glass, and fly larva.
