AI Technical Summary

Technical Problem

Existing methods for insect larval growth in industrial settings face challenges such as high storage space requirements, labor-intensive handling, and inefficiencies in separating and sorting small juvenile larvae, leading to yield loss and increased operational costs.

Method used

An insect larva rearing installation comprising pre-growth and growth modules with an inoculation system that allows for seamless transfer of juvenile larvae and frass between modules, minimizing handling and ensuring continuous access to feeding substrates without interruption, using conveyors and chutes for efficient substrate distribution.

Benefits of technology

Reduces storage space and handling operations, maintains continuous growth without yield loss, and optimizes larval rearing on a large scale by adapting module sizes and substrate composition to larval needs, thereby lowering costs and accelerating production flows.

Abstract

The present invention relates to an installation (10) for breeding insect larvae, the installation (10) comprising: - at least one pre-growth module (12) for receiving neonates and a first feeding substrate; - at least one growth module (14) for receiving juvenile larvae resulting from the pre-growth of the neonates, and a second feeding substrate; and - an installation (16) for inoculating the at least one growth module (14), the inoculation installation (16) comprising means (20) for conveying the pre-growth module(s) (12) and means (22) for transferring the contents of the pre-growth module(s) (12). The transfer means (22) are configured to transfer the contents of the pre-growth module(s) (12) into the growth module(s) (14).
