Abstract: The invention relates to a tray for farming insects, comprising a solid bottom (2) that defines a substantially horizontal plane, and side walls (4) defining a peripheral enclosure (5) of the tray. The bottom (2) and the side walls (4) define a tray body. The tray comprises feet (6) that extend vertically from the bottom (2) of the tray to a level above the enclosure (5) of the tray. The feet make it possible for an identical insect farming tray to be stacked on top of the farming tray while creating a space between the bottom (2) of said identical tray and the enclosure (5) of the tray. The body of the tray has no sharp edges in order to limit disruption to a laminar air flow flowing around the tray. The invention also relates to a stack of multiple trays of this type.

Abstract: The invention relates to a device (1) for rearing termites comprising a tray (2) containing a bed of a substrate (3) suitable for the life of termites, and a set of frames. A lignocellulosic material is placed in each frame (4). The frames are mounted removably side by side in parallel and vertically in the tray such that a lower edge of each frame rests on the substrate bed. The lower edge has one or more openings configured to allow at least some termites to pass between the substrate bed (3) and the interior of the frame (4). The lignocellulosic material of each frame is separated from the lignocellulosic material of the adjacent frame(s) (4) by at least one lateral wall.

Abstract: The invention relates to a process and a system for producing a textured edible protein product derived from insect larvae or worms. The process comprises a) reducing the insect larvae or worms in size to obtain a pulp, b) mixing the pulp with a hydrocolloid that gelates with metal cations in aqueous solution to form a protein-hydrocolloid slurry, and c) injecting the protein-hydrocolloid slurry into an aqueous solution of a metal cation with a valency of at least 2 to form the textured edible protein product. In step c) the protein-hydrocolloid slurry is jetted under pressure from outside of the aqueous solution of a metal cation with a valency of at least 2 into the aqueous solution at an oblique angle with respect to a liquid surface of the aqueous solution, thereby producing flakes of the textured edible protein product in the aqueous solution, in which flakes substantially all hydrocolloid has been gelated with the metal cations.
