AI Technical Summary

Technical Problem

Existing industrial systems for collecting and transporting neonate larvae, such as those of black soldier flies, face inefficiencies in hatching rates, continuous operation, precise quantification, and energy consumption, leading to production limitations and inaccuracies in larval counting.

Method used

An installation comprising egg collectors, a transfer line with flared walls and a conveyor system, a cyclone separator, and a dosing mechanism for precise weighing, ensuring efficient hatching, continuous transport, and accurate quantification of neonate larvae without energy-intensive air flows.

Benefits of technology

Enhances hatching rates, maintains continuous production, ensures precise quantification, and reduces energy consumption by using passive mechanical and pneumatic systems, thereby optimizing industrial larval rearing processes.

Abstract

The invention relates to an installation for the production and collection of neonate larvae comprising a set of cages equipped with at least one collector of eggs laid by the insects present in said cages, a transfer line of neonate larvae from the hatched eggs from each of said collectors to a conveyor and equipment for concentrating the neonate larvae from said conveyor for transport to a rearing module or to a buffer storage container of neonate larvae.It further comprises: a set of grouping bays for a plurality of egg collectors, said bays being open in their lower parts; said bays being mobile between a loading point with collectors removed from the cages and said neonate larvae transfer line; said neonate larvae transfer line being open, without a casing in the upper part, to receive said bays in the upper part, and having in the lower part a flared-walled guidance system, said receptacle, having in its upper part a width adapted to the section of said bays, and in its lower part an opening adapted to the dimensions of a conveyor, said receptacle being configured to group the neonate larvae falling by gravity from said collectors onto the upper surface of said conveyor.
