Abstract
The invention relates to a devive and a method for the continuous treatment of putrescent waste in which the waste is eaten by fly larvae. The device comprises: a conveyor belt; a means to distribute the waste; a means for depositing fly larvae eggs onto the waste; a means for removing fly larvae from the waste and from the conveyor belt; a means for removing the waste from the conveyor belt.
Claims27
A device for the continuous treatment of waste by means of fly larvae, in which the said fly larvae actually eat the waste, said device comprising:
- a conveyor belt having two lateral edges and consisting of at least a waste reception zone, a waste treatment zone and a waste evacuation zone;
- means to distribute the waste more or less evenly onto said conveyor belt;
- means for depositing fly larvae or fly larvae eggs onto the waste on the conveyor belt;
- means for removing fly larvae from the waste and from the conveyor belt, and comprising means for inducing fly larvae to crawl out of the waste towards at least one lateral edge of the conveyor belt and off the conveyor belt along said at least one lateral edge;
- and
- means for removing the waste from the conveyor belt.
Method for the continuous treatment of waste by means of fly larvae, in which the said fly larvae actually eat the waste, said method comprising the following steps:
- discharging and more or less evenly distributing putrescent waste onto a conveyor belt having two lateral edges;
- ensuring a movement of the conveyor belt;
- depositing fly larvae eggs onto the waste on the conveyor belt;
- ensuring the hatching of the eggs into larvae;
- ensuring a minimum residence time of the larvae in the waste so that substantially all the putrescent waste is eaten by the fly larvae and so that the majority of the fly larvae reach maturation;
- exposing a part of the waste to light and heat, in such a way that the fly larvae crawl out of the waste and off of the conveyor belt through at least one of its lateral edges, and
- removing the waste from the conveyor belt.
