The insect container has a bottom from a sieve or sift or gauze material. The mesh size of dimensions of the holes or passages should be such that an insect can reach through the openings in order to lay its eggs in a layer of feed below the insect container. On the other hand, insects should not be allowed to pass the sieve bottom. Usually, the sieve bottom comprises or is made of a metal comprising a fine metal
mesh screen on a frame. A loose or open gauze may also be used, as long as it retains the insects.
The assembly uses belt conveyor that comprise a belt that actuated. Free after Wikipedia: A conveyor belt is the carrying medium of a belt conveyor system (often shortened to belt conveyor). In an embodiment, a belt conveyor system comprises two or more pulleys (sometimes referred to as drums), with a closed loop of carrying medium — the conveyor belt — that rotates about them. One or both of the pulleys can be powered/actuated to rotate about their rotational axes, takin the belt with them for moving the belt and the material on the belt forward. In case of one drive pulley, the powered pulley is called the drive pulley while the unpowered pulley is called the idler pulley. In this description, often the term “conveyor belt” is used. This revers to a belt conveyor. In case the wording “surface of the conveyor belt” is used, it refers to the surface of the belt that is available for placing material upon.

In an embodiment, a mesh width is 1-4 mm. In a particular embodiment, the mesh will be 1-3 mm. For making the yield as high as possible, the layer of food is as thin as possible. In an embodiment, the layer of food on the egg conveyor belt is less than 1 cm thick.
In an embodiment, the insect container 4 comprise a circumferential wall for preventing insects to leave the insect container 4. In an embodiment, the insect container 4 may be covered with a lid or mesh for preventing the insects to leave the insect container 4.
The egg conveyor belt 2 here comprises an actuator 5 for driving said egg container belt 2. Usually, the actuator 5 comprises an electromotor and a controller functionally coupled to the electromotor for controlling it.
The container lift system 3 is provided for lifting the insect container 4 from the egg conveyor belt 2, and for lowering the insect container 4 onto the egg conveyor belt 2. In the depicted embodiment, the container lifting system 3 comprises at least one bar or lift rod 7. This lift rod 7 is mounted above the egg conveyor 2, in particular above and functionally parallel to the egg conveyor 2. The insect container 4 is coupled to the
lift rod 7 via cables or chains 8. Using an actuator, here an electromotor 11, the lift rod 7 can be rotated about its longitudinal axis. This will wind the cables or chains 8 around the lifting rods 7 and thus raise or lower the insect container 4 with respect to the egg conveyor belt 2.
The insect container 4 in the depicted embodiment comprises a series of insect crates 6. These insect crates are provided in a layer of insect crates 6. In an embodiment, the crates are rectangular. They can have and size, but it was found that they can have a size of about 25-100 length x 25-100 cm width. This size allows them to be manually handled. In the embodiment with circumferential wall, each insect crate 6 comprises a circumferential wall. Each insect crate 6 may comprise a closure further preventing insects to leave the crate 6. The closure may comprise a lid or a mesh.
In an embodiment, the insect container lift system 3 comprises a frame holding the insect crates 6 together. In an alternative embodiment, the insect crates 6 comprise a crate coupling provision allowing the insect crates to be mutually coupled in order to allow lifting of the series of insect crates 6 together as one part as explained. Such a coupling may comprise a snap fit coupling. The crate coupling can be provided on an outside of a circumferential wall.
The insect egg harvesting assembly 1 further comprises a moistening device 9 extending along the egg conveyor belt 2. In an embodiment, the moistening device 9 extends in a longitudinal direct of the egg conveyor belt 2. The moistening device 9 is provided along a side of the egg conveyor belt 2. It is provided with a series of spray nozzles (indicated with circles) for spraying a mist of water on the egg conveyor belt 2 when the insect container 4 has been lifted from the egg conveyor 2. On the opposite side along the egg conveyor belt, a ventilation device 10 is provided. The ventilation device 10 comprises a series of air inlet/outlets along the egg conveyor belt 2. When sucking in air, the ventilation device 10 assist in distributing the water mist from the moistening device 9.
In an alternative embodiment (not depicted), the moistening device extends along the conveyor, in particular above the conveyor. In this embodiment, it is arranged for spraying on the conveyor. In a particular embodiment, the moistening device comprises a main conduit running along the length of the conveyor, and comprises branching conduits running in width direction of the conveyor. The main conduit can run at a side of the conveyor and for instance elevated from the conveyor
surface. Branching conduits are for instance provided at regular intervals, in an embodiment with 30-600 cm interspacing, in an embodiment 100-500 cm. Each branching conduit can be provided with at least one spraying nozzle spraying in the longitudinal direction of the conveyor. In particular, the nozzles are directed to spray substantially parallel to the belt. The moistening device can be provided for an egg conveyor, for a breeding conveyor, or for both.25-
The insect egg harvesting assembly in an embodiment further comprises a egg conveyor feed dispensing system 19 for distributing larvae feed, often comprising flour, on the egg conveyor belt 2. In an embodiment, the egg conveyor feed dispensing system is provided at an end of the egg conveyor. The dispensing system can distribute a flow of larvae feed in a strip of an egg conveyor width. When running the conveyor belt 2, the larvae feed 12 will distribute on the complete egg conveyor belt surface. Usually, the layer should be as thin as possible in order to get a high yield. In most cases, such a layer has a thickness of below 2 cm. A layer thickness of about 1 cm proved possible. The egg conveyor feed dispensing system 19 may comprise a transport screw for distributing the feed 12 on the (width of the) belt, producing a layer while running the conveyor belt will assure a layer on the entire length of the belt 2. The moistening device 9 can subsequently moistening the larvae feed 12, and the insect container 4 can be lowered on the larvae feed 12 on the egg conveyor belt 2.
Figure 3 shows an insect breeding system comprising in this embodiment two insect egg harvesting assemblies 1 and two breeding conveyor belts 13, 14 above one another. These parts are enclosed or enclosed in a compartment 16. In fact, the compartment 16 is designed for hermetically sealing the parts. In this way, the environment conditions (temperature, humidity, amount of air) can be maintained. Furthermore, ingress is detrimental elements like pests can be prevented. Here, when a pest gets onto a conveyor belt, the entire system needs to be disinfected.
In this embodiment, each breeding conveyor belt comprises a feed distributing device 20. In this case, as eggs or larvae are distributed as even as possible on the complete length of the belt, the feed distributing device here comprises a distributor that extends along the length of the belt 13, 14. This distributes feed evenly on the belt, which is important for getting a high yield. Each belt in an embodiment comprises a moistening device 9 and ventilation device 10 as described above. The belt system allows to keep a predetermined density of eggs per unit surface area, and further down
the process a predetermined density of larvae per unit surface area on a conveyor. In fact, the density can be controlled and modified as larvae grow.
Usually, the various devices are controlled using a controller 15. To that end, the controller is functionally coupled, as indicated. This can be hard wired or wireless. Often, various breeding systems are combined into an insect breeding assembly.
Often, one single controller 15 controls the different insect breeding systems.
It will also be clear that the above description and drawings are included to illustrate some embodiments of the invention, and not to limit the scope of protection. Starting from this disclosure, many more embodiments will be evident to a skilled person. These embodiments are within the scope of protection and the essence of this invention and are obvious combinations of prior art techniques and the disclosure of this patent.
