Definitions

  • the invention relates to a modular breeding system for insects with a breeding box for receiving and breeding insects and with a technology box for supplying the breeding box with conditioned air.
  • the invention also relates to a use of the breeding system for breeding insects.
  • thermal energy and moisture are supplied and removed from the boxes in order to achieve the desired climatic conditions for optimal larvae growth. These conditions can be, for example, 27 ° C and 60% relative humidity.
  • air movement in the storage room is often forced through technical devices such as fans, or parts of the boxes can be made of an air-permeable or perforated material so that air can circulate within boxes stacked on top of one another.
  • closed boxes are also used. These boxes can also be placed in a specially made shelving system and have additional devices that are provided, for example, for laying eggs or for separating the various life stages of the insects. These closed boxes can have individual or central ventilation and heating in order to achieve the desired climatic conditions within the boxes.
  • the optimal conditions for the rapid growth of the larvae are known. So on the one hand the environmental conditions and the ventilation can be adapted to the respective condition of the larvae (e.g. age) and, on the other hand, the humidity can be regulated. With these measures, a significant increase in the fattening yield can be achieved.
  • the implementation on a large scale for example using a high-bay warehouse, there are a number of problems here.
  • One problem is to provide the larvae with sufficient water in an inexpensive manner without causing mold to grow.
  • One way of irrigating the larvae is to take the pallets out of the warehouse several times a day and water them at a central point.
  • irrigation is largely avoided in industrial breeding or attempts are made to cover the water requirement by increasing the air humidity or adding fresh vegetables.
  • this is only insufficiently possible due to the risk of mold formation.
  • irrigation is also carried out manually, which, however, is associated with increased personnel costs and cannot be implemented within a high-bay warehouse.
  • Another problem is to ensure the air conditioning of the high-bay warehouse, which represents a significant expense in terms of investment volume and ongoing operating costs. This also restricts the selection and minimum size of the location, as smaller systems are often uneconomical.
  • the climatic conditions and ventilation should be adapted to the age of the larvae.
  • One possibility is to subdivide the camp into different, smaller climatic zones so that there is one climatic zone for each age group.
  • Another option is to fill the entire warehouse with just one age group. However, this results in a very inefficient utilization of the production facility. Another problem is determining the condition of the larvae and the breeding environment remotely without direct interaction. Only then is real automation of the rearing possible, as the naturally existing variation can be compensated for, e.g. determining the right time for refeeding or harvesting.
  • the object is achieved in that an outlet opening for the conditioned air is provided on the technology box, that an air inlet duct is provided on the cultivation box, which connects an underside of the cultivation box with an opposite upper side of the cultivation box, the inlet air duct being a first on the underside has an open inlet duct end and on the upper side has an opposite, second open inlet duct end, that an inlet air opening is provided on the inlet air duct between the inlet air duct ends, which connects the inlet air duct with an interior of the grow box, and that the grow box can be stacked on the technology box in such a way that the outlet opening of the technology box is connected to the first end of the supply air duct of the supply air duct of the cultivation box, so that the conditioned air from the technology box can be supplied to the interior of the cultivation box via the supply air duct and the supply air opening.
