Abstract: An apparatus for growing invertebrates, such as arthropods, rheumatoid worms and nematodes is described. The apparatus includes a rotatable casing defining a chamber and at least one growing platform inside said casing. Inside the casing there is a group of first pipes having a pipe wall. The first pipes are configured to act as growing platforms providing growing spaces for the invertebrates. Preferably the number of first pipes is more than three. The first pipes may be immovably attached to the casing.

Abstract: As set out in this disclosure, the growing surface of invertebrates is increased and circumstances for the invertebrate are optimized by a growing apparatus that includes a rotatable casing and a growing chamber inside the casing. Inside the casing is at least one growing platform and the growing platform comprises one or more growing plates. The growing platform is configured in such a way that the growing plate can be kept in the same position even when the casing is rotated. This enables mixing the added food and other compounds in the growing chamber and thus prevents the food layers from becoming too thick while at the same time provides an undisturbed environment for the invertebrates.

Abstract: In the invention the growing surface of an apparatus for growing invertebrates is increased by a body or bodies (202) located in a growing chamber (201). When food is added to the growing chamber it is spread over at least some of the surfaces of bodies and the inner wall (203) of the growing chamber. This means that the area where invertebrates can grow is increased. The body or bodies are movable with respect to the inner wall of the growing chamber. This allows mixing the added food and other compounds in the growing chamber and it keeps air routes between bodies open.
