Fig. 1 presents a rearing pod 100 for rearing food-grade insects on an industrial scale.

The insects can be e.g. maggots, e.g. mealworms, or crickets, or grasshoppers.

The pod 100 comprises a bottom part 1 10 and a wall part 1 12. The bottom part 1 10 is connected to a lower portion 1 13 of the wall part 1 12 so that the parts 1 10, 1 12 form a rectangular bag (box)-like geometry of the pod 100 and define a rearing space 1 15 for insects. The parts 1 10, 1 12 are manufactured from a semi-rigid foldable (collapsible) material, which keeps its intended form when it is properly supported. If the parts 1 10, 1 12 are without any support, it is possible to fold the parts 1 10, 1 12 into a very small volume in order to facilitate logistics. In addition, the parts 1 10, 1 12 can be manufactured from a plastic, e.g. a polypropylene plastic.

Each of the parts 1 10, 1 12 can be manufactured from a single piece or several pieces.

The pod 100 can comprise the part 1 10, which is made from one piece, and the part 1 12, which is made from 2, 3, or 4 pieces.

In addition, the parts 1 10, 1 12 are arranged to surround the space 1 15 from five directions so that an inner surface of the part 1 10 and an inner surface 1 16 of the part 1 12 face the space 1 15.

The space 1 15 forms an incubation vessel for the insects. It is possible to increase a usable area of the space 1 15 by a rearing material.

The rearing material can be a honeycomb-like cardboard matrix or a cardboard chaff.

The space 1 15 makes possible to mount feed and water vessels inside the pod 100 without altering its geometry. The part 1 12 comprises an upper portion 1 14 that defines an opening 1 17 and its size.

The opening 1 17 makes possible to put the insects and the rearing material into the space 1 15, to maintain the insects, and to remove necessary issues from the space 1 15 through the large opening 1 17. The pod 100 can have following dimensions: a width w can be e.g. 900, 1000, or 1 100 mm, a depth d can be e.g. 500, 600, or 700 mm, and a height h can be e.g. 500, 550, or 600 mm.

In addition, the pod 100 can comprise loop parts 120, which are arranged to an outer surface of the upper portion 1 14 or to an upper edge 1 18 of the upper por- tion 1 14, in order to attach at least one wooden suspension rod 122 to the pod 100.

The at least one rod 122 can comprise one rod, two rods according to the figure, or one rectangular or square rod frame. The rod(s) 122 makes possible to move the pod 100 from one place to another and to hang up the pod 100 to a shelving frame 240.

In addition, the rod(s) 122 can rigidity the bag-like geometry.

In addition, the rod(s) 122 can be a bamboo rod(s).

The lower portion 1 13 can comprise at least two slots 124 for external support struts 126.

The slots 124 can comprise 2, 3, or 4 slots, and each slot 124 makes possible to install one wooden strut 126 inside it.

The struts 126, which are installed in the slots 124, rigidity the bag-like geometry.

In addition, the struts 126 can be bamboo struts. However, the pod 100 retains sufficient geometry without the external support struts 126.

The upper portion 1 14 comprises a plastic strip 130 on the inner surface 1 16 so that it covers continuously an inner surface 1 19 of the opening 1 17.

The strip 130 can be manufactured from a single piece or several pieces. In addition, the strip 130 can be manufactured from a polyethene plastic

A height s of the strip 130 can be e.g. 140, 150, or 160 mm.

In addition, the strip 130 can be attached by means of an attachment seam 132 so that an upper edge of the strip 130 is on the same level as the upper edge 1 18.

The seam 132 is attached e.g. 28, 30, 32 mm above a lower edge of the strip 130 so that it is formed a flap-like structure.

The slippery strip 130 prevents the insects to climb along the part 1 12 and escape from the pod 100. In addition, the flap-like structure of the strip 130 prevents the insects to use the seam 132 in order to move along to seam 132 to inner corners 134 of the pod 100 and use the corners 134 in order to escape from the pod 100.

The strip 130 eliminates a need for a separate cover, whereupon it is easy to ob- serve contents of the pods 100, and heat and gases can exchange freely.

The bag-like structure is lightweight, whereupon a single employee can handle it.

In addition, the lightweight structure makes a cleaning and maintenance of the pod 100 easy, which improves hygiene in the pod 100 and its surroundigs (a rearing space). The pod 100 is easily emptied for separation of the contents due to its mobility and non-rigid structure when the supports 122, 126 have been removed.

Fig. 2 presents the shelving frame 240 for rearing pods 1 10.

The frame 240 comprises vertical frame parts (walls) 250 and connection frame parts 254, and horizontal frame parts 260. Each part 250 comprises a vertical front part 252, a vertical rear part 253, and at least two connection parts 254 that connect the front and rear parts 252, 253 successively so that part 250 has a rectangular shape.
