Description

[Technical field]

[0001] The present invention relates to an insect larvae rearing device, in particular for black soldier fly larvae. [Background technology]

[0002] The growing demand for protein for livestock production and from a growing world population requires alternative protein sources. Insect larvae have a high protein content, can be fed organic waste and are significantly more climate friendly to rear than traditional protein sources. They are therefore suitable to supplement or completely replace protein-rich livestock feeds such as fishmeal.

[0003] In addition to providing an alternative protein source for livestock, livestock farmers also have the opportunity to utilize their own organic waste by using insect larvae. It therefore makes sense to carry out the majority of the rearing directly on the farm, allowing farmers to benefit from insect larvae not only in the form of protein-rich feed, but also as a natural waste disposal mechanism.

[0004] Up to now, the rearing of insect larvae has been mostly done manually. Rearing is understood here to mean, in particular, the removal of larvae from eggs. It is always desirable to have a high hatching rate and a large number of healthy larvae, which can then be processed into animal feed. In some cases, larva monitoring is installed to evaluate the condition of the larvae. From the evaluation of the condition of the larvae, conclusions can be drawn regarding the optimal harvest time and recommendations for actions, such as feeding or adjusting the environment in the insect larva rearing facility.

[0005] In the context of increasing decentralization, it is desirable to support systems to assess larval condition in order to optimize yields and achieve improved feed quality of animal feed obtained from insect larvae.

[0006] For example, the modular system described in US Pat. No. 6,399,633 includes sensors and cameras that allow remote monitoring of the larvae. A camera and a Bluetooth-enabled thermocouple are each disposed within the rearing tray, whereby the camera is configured to visually assess the condition of the larvae and the thermocouple is configured to measure the temperature of the insect larvae. The main drawbacks of this solution lie in the complex equipment set-up and the fact that the condition of the larvae is still assessed visually. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] International Publication No. 2019 / 053439 Summary of the Invention [Problem to be solved by the invention]

[0008] It is an object of the present invention to provide an improved device for assessing insect larval activity to assess the condition of the larvae. [Means for solving the problem]

[0009] This object is achieved in an insect larvae rearing apparatus of the above mentioned type by a first insect fattening container arranged to accommodate a first insect larvae cohort for fattening, an activity sensor device and a processing unit. The activity sensor device is arranged to detect at least one first humidity measurement value at at least one first humidity measuring point and provide it to the processing unit. The first humidity measuring point is preferably arranged in a central part of the insect fattening container.

[0010] In addition, the activity sensor device is configured to detect and provide at least one first temperature measurement value at at least one first temperature measurement point, the first temperature measurement point being preferably disposed in a central portion of the insect fattening container.

[0011] The processing unit is designed to process the detected first humidity measurement and the detected first temperature measurement and determine the activity of the insect larvae based on the processing results.

[0012] The activity of the insect larvae cohort in the first insect fattening container increases as the developmental stages progress. The distribution of the first insect larvae cohort in the first insect fattening container depends on the activity of the insect larvae cohort and therefore on the developmental state. Repeated observations have shown that the larvae of the black soldier fly are essentially evenly distributed in the insect fattening container at the beginning of the fattening process, and as their activity increases, they crowd in the central part of the insect fattening container and then also crowd on the edges of the insect fattening container. In the case of a cubic insect fattening container with a rectangular bottom, the insect larvae preferentially crowd in the corners of the insect fattening container. As a result, at different times during the development of the insect larvae, certain sections of the insect fattening container are occupied or not occupied by the insect larvae. The activity sensor device determines the activity of the insect larvae cohort, preferably without optical detection. This means that the activity sensor device preferably does not have an optical sensor, a camera or similar device for optical detection.

[0013] Using the activity sensor device according to the invention and the associated arrangement of one or more measurement points, relevant sections of the insect fattening vessel can be measured for activity determination purposes, so that the activity of the insect larvae cohort can be determined. The measurements are preferably used to position the insect larvae in the insect fattening vessel. It is also possible to preferably detect further temperature and / or humidity measurement points using the activity sensor device. Based on the measurements, the position of the insect larvae in the insect fattening vessel is determined.

[0014] In a particularly preferred refinement, the activity sensor device is configured to detect at least one second humidity measurement value at a second humidity measurement point and / or at least one third humidity measurement value at a third humidity measurement point and provide these to the processing unit, the second humidity measurement point being preferably spaced laterally from the first humidity measurement point and the third humidity measurement point being preferably spaced laterally from both the first and the second humidity measurement point.

[0015] The activity sensor device is also preferably configured to detect and provide to the processing unit at least one second temperature measurement at a second temperature measurement point and / or at least one third temperature measurement at a third temperature measurement point, the second temperature measurement point preferably being laterally spaced apart from the first temperature measurement point and the third temperature measurement point preferably being laterally spaced apart from both the first and second temperature measurement points.

[0016] With this preferred arrangement of the activity sensor device it is possible to better measure the relevant sections of the insect fattening vessel for the purpose of determining the larvae activity. The laterally spaced positioning of the measurement points means that the insect larvae can be reliably located within the insect fattening vessel.

[0017] In a preferred refinement, the second humidity measuring point is arranged on or adjacent to the side wall of the first insect fattening vessel. The second temperature measuring point is preferably arranged on or adjacent to the side wall of the first insect fattening vessel. The third humidity measuring point is preferably arranged on the edge of the first insect fattening vessel, particularly preferably at the corner. The third temperature measuring point is also preferably arranged on the edge of the first insect fattening vessel, particularly preferably at the corner. By positioning the measuring points in the central part of the first insect fattening vessel, on the side walls and corners and / or adjacent thereto, the insect larvae can be particularly reliably located in these sections of the first insect fattening vessel. These are also the sections of the first insect fattening vessel where the insect larvae swarm during the fattening process, as shown by repeated observations. It is preferred that further humidity and / or temperature measuring points are arranged in the first insect fattening vessel. Further humidity and / or temperature measuring points are preferably arranged on or adjacent to the side walls and / or corners of the insect fattening vessel. In a preferred refinement, humidity and / or temperature measuring points are arranged on all side walls of the insect fattening vessel. In a preferred refinement, humidity and / or temperature measuring points are arranged on all corners of the insect fattening vessel.

[0018] Preferably, the first humidity measurement point is disposed adjacent to the first temperature measurement point, the second humidity measurement point is disposed adjacent to the second temperature measurement point, and / or the third humidity measurement point is disposed adjacent to the third temperature measurement point, In this embodiment, both temperature and humidity measurements are detected in a section associated with determining activity.

[0019] Preferably, a first humidity sensor is arranged at the first humidity measuring point, a second humidity sensor is arranged at the second humidity measuring point and / or a third humidity sensor is arranged at the third humidity measuring point. It is particularly preferred that the first, second and / or third humidity sensor are capacitive humidity sensors.

[0020] In a preferred refinement, a first temperature sensor is arranged at the first temperature measuring point, a second temperature sensor is arranged at the second temperature measuring point and / or a third temperature sensor is arranged at the third temperature measuring point.

[0021] It is further preferred that the insect larvae rearing apparatus comprises a second insect fattening vessel configured to accommodate a second cohort of insect larvae for fattening. In this embodiment, it is preferred that the activity sensor device detects the measurement value in a manner similar to the detection of the measurement value in the first insect fattening vessel. In addition, the further insect fattening vessel configured to accommodate the further cohort of insect larvae for fattening may be provided with a similar measurement device. For the positioning of the measurement value in the first, second and other insect fattening vessels, please refer to the above description of the first insect fattening vessel.

[0022] The first, second and optional further insect fattening containers are arranged in the insect larvae rearing apparatus, for example, not only vertically on top of one another, but also horizontally next to one another or both vertically and horizontally. This is advantageous when the insect larvae rearing apparatus has a rearing area isolated from the environment, in which the first, second and further insect fattening containers are arranged and the air conditions in the rearing area are known, for example determined by sensors.

[0023] The sensor device can also be installed in rearing devices for insect larvae of species other than black soldier flies. For this purpose, it can be observed how the corresponding insect larvae genera are distributed and swarmed in the insect fattening containers with their activity levels. The arrangement of the measuring points should be such that a suitable section is measured to determine the activity of the corresponding insect larvae species.

[0024] The second invention further comprises a method for determining the activity of insect larvae using an insect larva rearing device, comprising the steps of adding a fattening substrate at the start of the fattening phase to fill the insect fattening container with insect larvae, and processing the detected first, second and third humidity measurements and the detected first, second and third temperature measurements at a first time t1 using a processing unit. It is particularly preferred that the fattening substrate added comprises a certain percentage of water. The fattening substrate added preferably comprises a certain percentage of water-binding substances. The fattening substrate added preferably comprises a certain percentage of nutrients. The percentage of water in the fattening substrate added is preferably in the range of 0% to 90%. The percentage of water-binding substances in the fattening substrate added is preferably in the range of 10% to 100%. The percentage of nutrients in the fattening substrate added is preferably in the range of 0% to 100%. The water-binding substrate is, for example, bran, water-binding gel or other water-binding elements. The fattening base preferably has a porridge-like consistency when added. During the fattening process, the proportion of water in the fattening base decreases. As a result, the fattening base changes in consistency and becomes free-flowing and divisible.

[0025] The processing of the detected measured values ​​consists of several sub-steps: in a first sub-step, the first detected humidity measured value at time t1 is compared with a first humidity reference value at time t1, the second detected humidity measured value at time t1 is compared with a second humidity reference value at time t1, the third detected humidity measured value at time t1 is compared with a third humidity reference value at time t1, the first detected temperature measured value at time t1 is compared with a first temperature reference value at time t1, the second detected temperature measured value at time t1 is compared with a second temperature reference value at time t1 and / or the third detected temperature measured value at time t1 is compared with a third temperature reference value at time t1.

[0026] The first, second and / or third humidity reference values ​​at time t1 may be different reference values ​​or the same reference value. Each humidity reference value at time t1 is preferably obtained from repeated observations of humidity measurements of the fattening substrate at time t1 and may be stored in or retrieved from the processing unit. The consistency of the fattening substrate is preferably a porridge-like consistency at the time of addition. During the fattening process, the proportion of water in the fattening substrate decreases. As a result, the consistency of the fattening substrate changes and becomes free-flowing and divisible.

[0027] Similarly, the first, second and third temperature reference values ​​at time t1 may be different reference values ​​or the same reference value. Each temperature reference value at time t1 is preferably obtained from repeated observations of temperature measurements of the fattening substrate at time t1 and may be stored in or retrieved from the processing unit.

[0028] In a second sub-step, an undershoot of the reference value is preferably determined at time t1 if one or more of the detected measurements falls below the respective reference value, and an overshoot of the reference value is preferably determined in a third sub-step at time t1 if one or more of the detected measurements exceeds the respective reference value.

[0029] Preferably, it is recognized that there is no clustering of insect larvae at time t1 at one or more of the humidity and / or temperature measurement points where the undershoot of the reference value or the correlation between the reference value and the detected measurement value is within ±2%, preferably ±5%, more preferably ±10%.

[0030] In a fourth preferred sub-step, clustering of the insect larvae at time t1 is determined at one or more of the humidity and / or temperature measurement points if an overshoot of the reference value is detected at said one or more humidity and / or temperature measurement points at time t1.

[0031] If the reference value is exceeded at one or more of the humidity and / or temperature measurement points, it can be assumed that the measurement values ​​are falsified due to clustering of the insect larvae at one or more of the humidity and / or temperature measurement points. This means that not only the humidity or temperature of the fattening substrate but also an increase in the humidity or temperature of the swarming insect larvae is detected. If the insect larvae swarm at a measurement point, this affects the measurement value. In contrast, the measurement values ​​detected at the measurement points where the insect larvae are not swarming are not further affected. For this reason, the clustering can be determined at the corresponding points. These measurement values ​​are used to place the insect larvae at time t1 in the insect fattening container. Visual observation of the insect larvae to evaluate the positioning of the insect larvae in the insect fattening container is not necessary.

[0032] In a preferred fifth sub-step, the determined clustering of the insect larvae at time t1 is compared with a reference clustering of the insect larvae at time t1. If the determined clustering of the insect larvae at time t1 corresponds to the reference clustering of the insect larvae at time t1, then preferably in a sixth sub-step, the regular activity of the insect larvae at time t1 is determined. However, if the determined clustering of the insect larvae at time t1 deviates from the reference clustering of the insect larvae at time t1, then the irregular activity of the insect larvae at time t1 is preferably determined in a seventh sub-step. Finally, preferably in an eighth sub-step, a development status signal is output at time t1 in response to the determined activity of the insect larvae at time t1.

[0033] The reference clustering at time t1 is preferably determined from repeated observations of the clustering or distribution pattern of the insect larvae during the fattening process at time t1 and can be stored in or retrieved by the processing unit. As a result of the observations, it was found that at the beginning of the fattening phase, the insect larvae are essentially evenly distributed in the insect fattening container. As activity increases, the insect larvae first cluster in the central part of the insect fattening container, and then also cluster at the edges or corners of the insect fattening container.

[0034] A correlation between the determined clustering and the reference clustering exists if, from observations, clustering is known to be present at time t1 at said one or more of the humidity and / or temperature measurement points where clustering of insect larvae has been noted. Thus, the insect larvae exhibit regular activity as known from repeated observations.

[0035] Deviations between the determined clustering and the reference clustering are present, especially when it is known from the observations that at said one or more of the humidity and / or temperature measuring points, where clustering of insect larvae has been noticed, there is usually no clustering at time t1. As a result, an irregular activity of the insect larvae is determined. This may point to disease, unsuitable weather or poor nutrition. This allows appropriate measures to be taken.

[0036] The method preferably further comprises processing the detected first, second and / or third measured humidity values ​​and / or the detected first, second and / or third measured temperature values ​​using a processing unit at the second time t2, the third time t3, the fourth time t4, the fifth time t5, the sixth time t6 and / or the seventh time t7. In principle, any number of time points may be provided in the process, and thus the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 or any other number may be provided. These measurements are used to place insects in the insect fattening container at different times. As a result, the movement of insect larvae in the insect fattening container may be tracked over a period of time.

[0037] Between time t1 and time t2, there is preferably a period of 1 to 48 hours, more preferably 12 to 24 hours, and particularly preferably around 24 hours. Preferably, there is approximately the same length of time between the time points to increase comparability.

[0038] Between time t2 and time t3, there is also a period of 1 to 48 hours, preferably 12 to 24 hours, and particularly preferably about 24 hours.

[0039] Preferably, between time t3 and time t4 there is also a period of 1 to 48 hours, preferably 12 to 24 hours, particularly preferably about 24 hours.

[0040] It is also preferred that between time t4 and time t5 there is a period of 1 to 48 hours, preferably 12 to 24 hours, and particularly preferably about 24 hours, and between time t5 and time t6 there is a period of 1 to 48 hours, preferably 12 to 24 hours, and particularly preferably 24 hours.

[0041] Between time t6 and time t7, there is also a period of 1 to 48 hours, preferably 12 to 24 hours, and particularly preferably around 24 hours.

[0042] The processing of the measured values ​​recorded at time t2 comprises several sub-steps: in a first sub-step, the first measured humidity value detected at time t2 is first compared with a first humidity reference value at time t2, the second measured humidity value detected at time t2 is compared with a second humidity limit value at time t2, the third measured humidity value detected at time t2 is compared with a third humidity reference value at time t2, the first measured temperature value detected at time t2 is compared with a first temperature reference value at time t2, the second measured temperature value detected at time t2 is compared with a second temperature reference value at time t2 and the third measured temperature value detected at time t2 is compared with a third temperature reference value at time t2.

[0043] The first, second and third humidity reference values ​​at time t2 may be different reference values ​​or may be the same reference value. Each humidity reference value at time t2 is preferably determined from repeated observations of the measured humidity values ​​of the fattening substrate at time t2 and may be stored in or retrieved from the processing unit.

[0044] Similarly, the first, second and third temperature reference values ​​at time t2 may be different reference values ​​or the same reference value. Each temperature reference value at time t2 is preferably determined from repeated observations of the measured temperature values ​​of the fattening substrate at time t2 and may be stored in or retrieved from the processing unit.

[0045] In a second sub-step, an undershoot of the reference value is preferably determined at time t2 if one or more of the recorded measurements fall below the respective reference value, and an overshoot of the reference value is preferably determined in a third sub-step at time t2 if one or more of the recorded measurements exceed the respective reference value.

[0046] Preferably, at one or more of the humidity and / or temperature measurement points where there is an undershoot of the reference value or agreement between the reference value and the recorded measurement value is within ±2%, preferably ±5%, more preferably ±10%, there is recognized to be no clustering of insect larvae at time t2.

[0047] In a fourth preferred sub-step, clustering of the insect larvae at time t2 is determined at one or more of the humidity and / or temperature measurement points if an overshoot of the reference value is detected at said one or more humidity and / or temperature measurement points at time t2.

[0048] If the reference value is exceeded at one or more of the humidity and / or temperature measurement points at time t2, it can be assumed that the measurements have been falsified due to clustering of the insect larvae at one or more of the humidity and / or temperature measurement points. This means that not only the humidity or temperature of the fattening substrate at time t2 but also the increase in humidity or temperature of the swarming insect larvae is recorded. These measurements are used to place the insect larvae at time t2 in the insect fattening container.

[0049] In a preferred fifth sub-step, the determined clustering of the insect larvae at time t2 is compared with a reference clustering of the insect larvae at time t2. If the determined clustering of the insect larvae at time t2 corresponds to the reference clustering of the insect larvae at time t2, then preferably in a sixth sub-step, the regular activity of the insect larvae at time t2 is determined. However, if the determined clustering of the insect larvae at time t2 deviates from the reference clustering of the insect larvae at time t2, then the irregular activity of the insect larvae at time t2 is preferably determined in a seventh sub-step. Finally, preferably in an eighth sub-step, a development status signal is output at time t2 in response to the determined activity of the insect larvae at time t2.

[0050] The reference clustering at time t2 is preferably determined from repeated observations of the clustering or distribution pattern of the insect larvae during the fattening process at time t2 and may be stored in or retrieved by the processing unit.

[0051] A match between the determined clustering and the reference clustering exists if, from observations, clustering is known to be present at time t2 at said one or more of the humidity and / or temperature measurement points where clustering of insect larvae has been noted, and thus the insect larvae show regular activity at time t2 as known from repeated observations.

[0052] A deviation exists between the determined clustering and the reference clustering, especially if it is known from observations that at said one or more of the humidity and / or temperature measuring points where clustering of insect larvae has been noticed, there is usually no clustering at time t2, so that an irregular activity of the insect larvae is determined at time t2.

[0053] The processing of the measured values ​​recorded at time t3 also preferably comprises several sub-steps, which are preferably similar to the sub-steps carried out as part of the processing of the measured values ​​recorded at time t1 and time t2. In a first sub-step, preferably, first the first measured humidity value detected at time t3 is compared with a first humidity reference value at time t3, the second measured humidity value detected at time t3 is compared with a second humidity limit value at time t3, the third measured humidity value detected at time t3 is compared with a third humidity reference value at time t3, the first measured temperature value detected at time t3 is compared with a first temperature reference value at time t3, the second measured temperature value detected at time t3 is compared with a second temperature reference value at time t3 and / or the third measured temperature value detected at time t3 is compared with a third temperature reference value at time t3.

[0054] The first, second and / or third humidity reference values ​​at time t3 may be different reference values ​​or may be the same reference value. Each humidity reference value at time t3 is preferably obtained from repeated observations of the measured humidity values ​​of the fattening substrate at time t3 and may be stored in or retrieved by the processing unit.

[0055] Similarly, the first, second and / or third temperature reference value at time t3 may be different reference values ​​or the same reference value. Each temperature reference value at time t3 is preferably obtained from repeated observations of the measured temperature value of the fattening substrate at time t3 and may be stored in or retrieved from the processing unit.

[0056] In a second sub-step, an undershoot of the reference value is preferably determined at time t3 if one or more of the recorded measurements fall below the respective reference value, and an overshoot of the reference value is preferably determined in a third sub-step at time t3 if one or more of the recorded measurements exceed the respective reference value.

[0057] Preferably, no clustering of insect larvae is detected at time t3 at one or more of the humidity and / or temperature measurement points where the undershoot of the reference value or the agreement between the reference value and the recorded measurement value is within a range of between ±2%, preferably ±5%, more preferably ±10%.

[0058] In a fourth preferred sub-step, clustering of insect larvae at time t3 at one or more of the humidity and / or temperature measurement points is determined if an overshoot of the reference value at time t3 is detected at said one or more humidity and / or temperature measurement points.

[0059] If the reference value is exceeded at one or more of the humidity and / or temperature measurement points at time t3, it can be assumed that the measurements have been falsified due to clustering of the insect larvae at one or more of the humidity and / or temperature measurement points. This means that at time t3, not only the humidity or temperature of the fattening substrate is recorded, but also the increase in humidity or temperature of the swarming insect larvae. These measurements are used to place the insect larvae at time t3 in the insect fattening container.

[0060] In a preferred fifth sub-step, the determined clustering of the insect larvae at time t3 is compared with a reference clustering of the insect larvae at time t3. If the determined clustering of the insect larvae at time t3 corresponds to the reference clustering of the insect larvae at time t3, then preferably in a sixth sub-step, the regular activity of the insect larvae at time t3 is determined. However, if the determined clustering of the insect larvae at time t3 deviates from the reference clustering of the insect larvae at time t3, then the irregular activity of the insect larvae at time t3 is preferably determined in a seventh sub-step. Finally, preferably in an eighth sub-step, a development status signal is output at time t3 in response to the determined activity of the insect larvae at time t3.

[0061] The reference clustering at time t3 is preferably determined from repeated observations of the clustering or distribution pattern of the insect larvae during the fattening process at time t3 and may be stored in or retrieved by the processing unit.

[0062] A match between the determined clustering and the reference clustering exists if, from observations, clustering is known to be present at time t3 at one or more of the humidity and / or temperature measurement points where clustering of insect larvae has been noted, and thus the insect larvae show regular activity at time t3 as known from repeated observations.

[0063] A deviation exists between the determined clustering and the reference clustering, especially if it is known from observations that at said one or more of the humidity and / or temperature measuring points where clustering of the insect larvae has been noticed, there is usually no clustering at time t3, so that an irregular activity of the insect larvae is determined at time t3.

[0064] The processing of the measured values ​​recorded at time t4 preferably also includes several sub-steps, which are preferably similar to the sub-steps performed as part of the processing of the measured values ​​recorded at time t1, t2 and t3. In a first sub-step, preferably, first the first measured humidity value detected at time t4 is compared with a first humidity reference value at time t4, the second measured humidity value detected at time t4 is compared with a second humidity limit value at time t4, the third measured humidity value detected at time t4 is compared with a third humidity reference value at time t4, the first measured temperature value detected at time t4 is compared with a first temperature reference value at time t4, the second measured temperature value detected at time t4 is compared with a second temperature reference value at time t4 and / or the third measured temperature value detected at time t4 is compared with a third temperature reference value at time t4.

[0065] The first, second and / or third humidity reference values ​​at time t4 may be different reference values ​​or may be the same reference value. Each humidity reference value at time t4 is preferably obtained from repeated observations of the measured humidity values ​​of the fattening substrate at time t4 and may be stored in or retrieved by the processing unit.

[0066] Similarly, the first, second and / or third temperature reference value at time t4 may be different reference values ​​or the same reference value. Each temperature reference value at time t4 is preferably obtained from repeated observations of the measured temperature value of the fattening substrate at time t4 and may be stored in or retrieved from the processing unit.

[0067] In a second sub-step, an undershoot of the reference value is preferably determined at time t4 if one or more of the recorded measurements fall below the respective reference value, and an overshoot of the reference value is preferably determined in a third sub-step at time t4 if one or more of the recorded measurements exceed the respective reference value.

[0068] Preferably, at one or more of the humidity and / or temperature measurement points where there is an undershoot of the reference value or agreement between the reference value and the recorded measurement value is within ±2%, preferably ±5%, more preferably ±10%, there is recognized to be no clustering of insect larvae at time t4.

[0069] In a fourth preferred sub-step, the clustering of the insect larvae at time t4 at one or more of the humidity and / or temperature measurement points is determined if an overshoot of the reference value at time t4 is detected at said one or more humidity and / or temperature measurement points. These measurements are used to place the insect larvae at time t4 in the insect fattening container.

[0070] If the reference value is exceeded at one or more of the humidity and / or temperature measuring points at time t4, it can be assumed that the measurements have been falsified due to clustering of the insect larvae at one or more of the humidity and / or temperature measuring points. This means that at time t4, not only is the humidity or temperature of the fattening substrate recorded, but also an increase in the humidity or temperature of the swarming insect larvae.

[0071] In a preferred fifth sub-step, the determined clustering of the insect larvae at time t4 is compared with a reference clustering of the insect larvae at time t4. If the determined clustering of the insect larvae at time t4 corresponds to the reference clustering of the insect larvae at time t4, then preferably in a sixth sub-step, the regular activity of the insect larvae at time t4 is determined. However, if the determined clustering of the insect larvae at time t4 deviates from the reference clustering of the insect larvae at time t4, then preferably in a seventh sub-step, the irregular activity of the insect larvae at time t4 is determined. Finally, preferably in an eighth sub-step, a development status signal is output at time t4 in response to the determined activity of the insect larvae at time t4.

[0072] The reference clustering at time t4 is preferably determined from repeated observations of the clustering or distribution pattern of the insect larvae during the fattening process at time t4 and can be stored in the processing unit or retrieved by it.

[0073] A match between the determined clustering and the reference clustering exists if, from observations, clustering is known to be present at time t4 at said one or more of the humidity and / or temperature measurement points where clustering of insect larvae has been noted, and thus the insect larvae show regular activity at time t4 as known from repeated observations.

[0074] A deviation between the determined clustering and the reference clustering exists in particular if it is known from observations that at said one or more of the humidity and / or temperature measuring points where clustering of the insect larvae has been noticed, there is usually no clustering at time t4, so that an irregular activity of the insect larvae is determined at time t4.

[0075] The processing of the measured values ​​recorded at time t5 preferably also includes several sub-steps, which are preferably similar to the sub-steps performed as part of the processing of the measured values ​​recorded at time t1, t2, t3 and t4. In the first sub-step, preferably, first the first measured humidity value detected at time t5 is compared with a first humidity reference value at time t5, the second measured humidity value detected at time t5 is compared with a second humidity limit value at time t5, the third measured humidity value detected at time t5 is compared with a third humidity reference value at time t5, the first temperature measured value detected at time t5 is compared with a first temperature reference value at time t5, the second temperature measured value detected at time t5 is compared with a second temperature reference value at time t5 and / or the third temperature measured value detected at time t5 is compared with a third temperature reference value at time t5.

[0076] The first, second and / or third humidity reference values ​​at time t5 may be different reference values ​​or may be the same reference value. Each humidity reference value at time t5 is preferably obtained from repeated observations of the measured humidity values ​​of the fattening substrate at time t5 and may be stored in or retrieved by the processing unit.

[0077] Similarly, the first, second and / or third temperature reference value at time t5 may be different reference values ​​or the same reference value. Each temperature reference value at time t5 is preferably obtained from repeated observations of the measured temperature value of the fattening substrate at time t5 and may be stored in or retrieved by the processing unit.

[0078] In a second sub-step, an undershoot of the reference value is preferably determined at time t5 if one or more of the recorded measurements falls below the respective reference value, and an overshoot of the reference value is preferably determined in a third sub-step at time t5 if one or more of the recorded measurements exceeds the respective reference value.

[0079] Preferably, it is recognized that there is no clustering of insect larvae at time t5 at one or more of the humidity and / or temperature measurement points where the reference value undershoots or the agreement between the reference value and the recorded measurement value is within ±2%, preferably ±5%, more preferably ±10%.

[0080] In a fourth preferred sub-step, the clustering of insect larvae at time t5 at one or more of the humidity and / or temperature measurement points is determined if an overshoot of the reference value is detected at said one or more humidity and / or temperature measurement points at time t5.

[0081] If the reference value is exceeded at one or more of the humidity and / or temperature measurement points at time t5, it can be assumed that the measurements have been falsified due to clustering of the insect larvae at one or more of the humidity and / or temperature measurement points. This means that not only the humidity or temperature of the fattening substrate at time t5 but also the increase in humidity or temperature of the swarming insect larvae is recorded. These measurements are used to place the insect larvae at time t5 in the insect fattening container.

[0082] In a preferred fifth sub-step, the determined clustering of the insect larvae at time t5 is compared with a reference clustering of the insect larvae at time t5. If the determined clustering of the insect larvae at time t5 corresponds to the reference clustering of the insect larvae at time t5, then preferably in a sixth sub-step, the regular activity of the insect larvae at time t5 is determined. However, if the determined clustering of the insect larvae at time t5 deviates from the reference clustering of the insect larvae at time t5, then preferably in a seventh sub-step, the irregular activity of the insect larvae at time t5 is determined. Finally, preferably in an eighth sub-step, a development status signal is output at time t5 in response to the determined activity of the insect larvae at time t5.

[0083] The reference clustering at time t5 is preferably determined from repeated observations of the clustering or distribution pattern of the insect larvae during the fattening process at time t5 and may be stored in the processing unit or retrieved by it.

[0084] A match between the determined clustering and the reference clustering exists if, from observations, clustering is known to be present at time t5 at said one or more of the humidity and / or temperature measurement points where clustering of insect larvae has been noted, and thus the insect larvae show regular activity at time t5 as known from repeated observations.

[0085] A deviation between the determined clustering and the reference clustering exists in particular if it is known from observations that at said one or more of the humidity and / or temperature measuring points, where clustering of the insect larvae has been noticed, there is usually no clustering at time t5, so that an irregular activity of the insect larvae is determined at time t5.

[0086] The processing of the measured values ​​recorded at time t6 preferably also includes several sub-steps, which are preferably similar to the sub-steps performed as part of the processing of the measured values ​​recorded at time t1, t2, t3, t4 and t5. In a first sub-step, preferably, first the first measured humidity value detected at time t6 is compared with a first humidity reference value at time t6, the second measured humidity value detected at time t6 is compared with a second humidity limit value at time t6, the third measured humidity value detected at time t6 is compared with a third humidity reference value at time t6, the first measured temperature value detected at time t6 is compared with a first temperature reference value at time t6, the second measured temperature value detected at time t6 is compared with a second temperature reference value at time t6 and / or the third measured temperature value detected at time t6 is compared with a third temperature reference value at time t6.

[0087] The first, second and / or third humidity reference values ​​at time t6 may be different reference values ​​or may be the same reference value. Each humidity reference value at time t6 is preferably obtained from repeated observations of the measured humidity values ​​of the fattening substrate at time t6 and may be stored in or retrieved by the processing unit.

[0088] Similarly, the first, second and / or third temperature reference value at time t6 may be different reference values ​​or the same reference value. Each temperature reference value at time t6 is preferably obtained from repeated observations of the measured temperature value of the fattening substrate at time t6 and may be stored in or retrieved by the processing unit.

[0089] In a second sub-step, an undershoot of the reference value is preferably determined at time t6 if one or more of the recorded measurements falls below the respective reference value, and an overshoot of the reference value is preferably determined in a third sub-step at time t6 if one or more of the recorded measurements exceeds the respective reference value.

[0090] Preferably, it is recognized that there is no clustering of insect larvae at time t6 at one or more of the humidity and / or temperature measurement points where the reference value is not reached or the agreement between the reference value and the recorded measurement value is within ±2%, preferably ±5%, more preferably ±10%.

[0091] In a fourth preferred sub-step, clustering of insect larvae at time t6 at one or more of the humidity and / or temperature measurement points is determined if an overshoot of the reference value at time t6 is detected at said one or more of the humidity and / or temperature measurement points.

[0092] If the reference value is exceeded at one or more of the humidity and / or temperature measurement points at time t6, it can be assumed that the measurements have been falsified due to clustering of the insect larvae at one or more of the humidity and / or temperature measurement points. This means that not only the humidity or temperature of the fattening substrate at time t6 but also the increase in humidity or temperature of the swarming insect larvae is recorded. These measurements are used to place the insect larvae at time t6 in the insect fattening container.

[0093] In a preferred fifth sub-step, the determined clustering of the insect larvae at time t6 is compared with a reference clustering of the insect larvae at time t6. If the determined clustering of the insect larvae at time t6 corresponds to the reference clustering of the insect larvae at time t6, then preferably in a sixth sub-step, the regular activity of the insect larvae at time t6 is determined. However, if the determined clustering of the insect larvae at time t6 deviates from the reference clustering of the insect larvae at time t6, then the irregular activity of the insect larvae at time t6 is preferably determined in a seventh sub-step. Finally, preferably in an eighth sub-step, a development status signal is output at time t6 in response to the determined activity of the insect larvae at time t6.

[0094] The reference clustering at time t6 is preferably determined from repeated observations of the clustering or distribution pattern of the insect larvae during the fattening process at time t6 and may be stored in or retrieved by the processing unit.

[0095] A match between the determined clustering and the reference clustering exists if it is known from experience that clustering exists at time t6 at said one or more of the humidity and / or temperature measurement points where clustering of insect larvae has been noted from observations, and thus the insect larvae show regular activity at time t6 as known from repeated observations.

[0096] A deviation between the determined clustering and the reference clustering exists in particular if it is known from observations that at said one or more of the humidity and / or temperature measuring points where clustering of the insect larvae has been noticed, there is usually no clustering at time t6, so that an irregular activity of the insect larvae is determined at time t6.

[0097] The processing of the measured values ​​recorded at time t7 preferably also includes several sub-steps, which are preferably similar to the sub-steps performed as part of the processing of the measured values ​​recorded at time t1, t2, t3, t4, t5 and t6. In the first sub-step, preferably, first the first measured humidity value recorded at time t7 is compared with a first humidity reference value at time t7, the second measured humidity value recorded at time t7 is compared with a second humidity limit value at time t7, the third measured humidity value recorded at time t7 is compared with a third humidity reference value at time t7, the first detected temperature measured value at time t7 is compared with a first temperature reference value at time t7, the second detected temperature measured value at time t7 is compared with a second temperature reference value at time t7 and / or the third detected temperature measured value at time t7 is compared with a third temperature reference value at time t7.

[0098] The first, second and / or third humidity reference values ​​at time t7 may be different reference values ​​or may be the same reference value. Each humidity reference value at time t7 is preferably obtained from repeated observations of the measured humidity values ​​of the fattening substrate at time t7 and may be stored in or retrieved by the processing unit.

[0099] Similarly, the first, second and / or third temperature reference value at time t7 may be different reference values ​​or the same reference value. Each temperature reference value at time t7 is preferably obtained from repeated observations of the measured temperature value of the fattening substrate at time t7 and may be stored in or retrieved from the processing unit.

[0100] In a second sub-step, an undershoot of the reference value is preferably determined at time t7 if one or more of the recorded measurements falls below the respective reference value, and an overshoot of the reference value is preferably determined in a third sub-step at time t7 if one or more of the recorded measurements exceeds the respective reference value.

[0101] Preferably, it is recognized that there is no clustering of insect larvae at time t7 at one or more of the humidity and / or temperature measurement points where the reference value is not reached or the agreement between the reference value and the recorded measurement value is within ±2%, preferably ±5%, more preferably ±10%.

[0102] In a fourth preferred sub-step, clustering of insect larvae at time t7 at one or more of the humidity and / or temperature measurement points is determined if an overshoot of the reference value at time t7 is detected at said one or more humidity and / or temperature measurement points.

[0103] If the reference value is exceeded at one or more of the humidity and / or temperature measurement points at time t7, it can be assumed that the measurements have been falsified due to clustering of the insect larvae at one or more of the humidity and / or temperature measurement points. This means that at time t7, not only the humidity or temperature of the fattening substrate is recorded, but also the increase in humidity or temperature of the swarming insect larvae. These measurements are used to place the insect larvae at time t7 in the insect fattening container.

[0104] In a fifth preferred sub-step, the determined clustering of the insect larvae at time t7 is compared with a reference clustering of the insect larvae at time t7. If the determined clustering of the insect larvae at time t7 corresponds to the reference clustering of the insect larvae at time t7, then preferably in a sixth sub-step, the regular activity of the insect larvae at time t7 is determined. However, if the determined clustering of the insect larvae at time t7 deviates from the reference clustering of the insect larvae at time t7, then preferably in a seventh sub-step, the irregular activity of the insect larvae at time t7 is determined. Finally, preferably in an eighth sub-step, a development status signal is output at time t7 in response to the determined activity of the insect larvae at time t7.

[0105] The reference clustering at time t7 is preferably determined from repeated observations of the clustering or distribution pattern of the insect larvae during the fattening process at time t7 and may be stored in the processing unit or retrieved by it.

[0106] A match between the determined clustering and the reference clustering exists if, from observations, clustering is known to be present at time t7 at said one or more of the humidity and / or temperature measurement points where clustering of insect larvae has been noted, and thus the insect larvae show regular activity at time t7 as known from repeated observations.

[0107] A deviation between the determined clustering and the reference clustering exists in particular if it is known from observations that at said one or more of the humidity and / or temperature measuring points, where clustering of insect larvae has been noticed, there is usually no clustering at time t7, so that an irregular activity of the insect larvae is determined at time t7.

[0108] The method for transporting insect larvae preferably includes the steps of continuing the fattening phase if the development status signal indicates regular activity of the insect larvae and interrupting the fattening phase if the development status signal indicates irregular activity of the insect larvae.

[0109] Thus, the fattening phase can be interrupted at any of the times t1, t2, t3, t4, t5, t6 or t7, allowing the user of the insect larvae rearing device to intervene in the fattening process. This allows for early intervention in the fattening process if irregular activity of the insect larvae is recognized.

[0110] If the fattening process continues without interruption, the insect larvae can be harvested at time t7 or at a defined time after time t7. If the measuring points are appropriately arranged, it is also possible to predict the amount of insect larvae harvested, which makes it possible to determine not only the formation of clusters, but also their size.

[0111] In a preferred refinement, the method further comprises the steps of determining an average temperature based on the first, second and / or third measured temperature values ​​at times t1, t2, t3, t4, t5, t6 and / or t7, determining a substrate evaporation based on the determined average temperature and a given air humidity, and determining a dry matter content of the fattening substrate based on the determined fattening substrate evaporation.

[0112] The dry matter content estimate may be used to correct for falsification of measurements due to clustering of insect larvae at one or more of the humidity and / or temperature measurement points.

[0113] The present invention also achieves the above object by means of a computer program comprising a program code which, when executed on a processing unit of an insect larvae rearing apparatus, causes the processing unit to carry out a method according to one of the above-mentioned preferred embodiments of the method according to the fourth consideration of the invention.

[0117] The mobile transport device 1 according to the first consideration has a housing 2 with insulation 52, an air intake section 40, and an air exhaust section 42 (FIG. 1). Although the mobile transport device 1 is described herein as mobile, i.e., transportable and intended for transport, it should be understood that its functions and features are also useful in stationary devices for rearing and breeding insect larvae, and that these functions and features may also be advantageously used in stationary devices. Although the mobile transport device 1 is initially described without an activity sensor device 54, it should be understood that the mobile transport device may be provided with one or more activity sensor devices 54, as will be described in more detail, particularly with reference to FIGS. 21 and 22.

[0118] A receiving section 4 is provided in the housing, in which four insect fattening containers 6.1-6.4 are arranged in the embodiment example of FIG. 1. The receiving section 4 is divided into four compartments 22.1-22.4 (see FIG. 2) for receiving the four insect fattening containers 6.1-6.4, which are arranged vertically essentially over the entire cross section of the mobile transport device 1 (see FIGS. 2 and 4). In this embodiment example, the insect fattening containers 6.1-6.4 can be selectively inserted and removed in the compartments 22.1-22.4. Preferably, the insect fattening containers 6.1-6.4 are filled with insect larvae and fattening substrate before being transported to the compartments 22.1-22.4. This can be done manually, for example by an employee. The fattening area of ​​the insect fattening containers 6.1-6.4 is preferably 0.5 m 2 From 0.7m 2 The fattening substrate, which is initially added to the insect fattening containers 6.1-6.4, contains a certain percentage of water. The fattening substrate added preferably contains a certain percentage of water-binding substances. The fattening substrate added preferably contains a certain percentage of nutrients. The fattening substrate loses moisture during the fattening process. The insect larvae, the water-binding substances, and / or the ventilation / air conditioning remove the moisture from the fattening substrate. As a result, the consistency of the fattening substrate changes.

[0119] After transport, the individual insect fattening containers 6.1-6.4 are then removed from the compartments 22.1-22.4. They can then be transported, for example, by the recipient to existing facilities at the destination for further rearing and feeding, or harvested directly when mature. The mobile transport device 1 of the present invention allows further feeding and rearing even during transport, which can improve the efficiency of reproduction and even the quality of the larvae.

[0120] The receiving section 4 divides the interior 24 of the housing 2 into an exhaust section 28 and a ventilation section 26, the function of which will be explained in more detail below. The four compartments 22.1-22.4 each have an air conditioning device 12.1-12.4, which in turn each have a ventilation section 14.1-14.4 and an exhaust section 16.1-16.4. In the example of the embodiment of FIG. 1, the ventilation sections 14.1-14.4 each form a first side wall of a compartment, and the exhaust sections 16.1-16.4 each form a second side wall of a compartment. The first and second side walls are arranged opposite each other. The ventilation sections 14.1-14.4 also comprise flow cross sections 20.1-20.4 (see FIG. 2), which are adjustable by means of a ventilation control unit 18 arranged in the lower section of the mobile transport device 1.

[0121] The recirculation fan 8 is arranged in the upper section of the mobile transport device 1 inside the housing 2. During operation, the recirculation fan 8 conveys air from the exhaust section 28 to the ventilation section 26, thereby forming an air-conducting connection between the exhaust section 28 and the ventilation section 26. The first, second, third and fourth air-conditioning devices 12.1-12.4 form a further air-conducting connection between the barking ventilation part 26 and the ventilating part 28. The recirculation fan 8 is controlled by an electronic control unit 10 arranged in the lower section of the mobile tramming device 1. The recirculation fan 8 is inserted in a partition wall that closes the entire clear cross section between the inner wall of the housing 2 and the remaining receiving section 4, so that the ventilation section 26 and the ventilating part 28 are connected only via the recirculation fan 8 on the one hand and via the air-conditioning devices 12.1-12.4 on the other hand. This ensures that the air conveyed by the recirculation fan 8 actually reaches the individual insect fattening containers 6.1-6.4 and aerates the insect larvae contained therein.

[0122] A storage vessel 30 is also arranged in the housing 2, which in this example embodiment is also accommodated in the receiving section 4, although in other example embodiments it may be arranged elsewhere. The storage tank 30 is arranged in a vertical arrangement with the four compartments 22.1-22.4 forming the lower end of the arrangement. In the example embodiment of FIG. 1, the storage tank 30 comprises additional insulation 52. An air conditioning material 31, such as zeolite for air dehumidification, is reversibly accommodated in the storage vessel 30.

[0123] The storage tank 30 has a storage tank ventilation section 32 on a first side and a storage tank exhaust section 34 on a second side opposite the first side. The storage tank ventilation section 32 also has a storage tank flow cross section 38 that is adjustable using a storage tank control unit 36 ​​(see FIG. 2).

[0124] The storage tank flow cross section 38 is fully closed in the example embodiment of Figures 1 and 2, so that air from the ventilation section 26 cannot enter the storage tank 30. If it is determined that the humidity of the internal air is too high, the storage tank ventilation section 32 is partially or fully opened, so that air can also circulate in the storage tank 30, thus lowering the humidity of the air. Instead of zeolite as the air conditioning material 31, other materials, for example cooling materials, can also be envisaged, and the temperature of the air can be influenced by the corresponding activation of the storage tank ventilation section 32 and the recirculation fan 8.

[0125] The reservoir control unit 36, like the electronic control unit 10 and the ventilation control unit 18, is arranged in the lower section of the mobile transport device 1. In the example embodiment of FIG. 1, the reservoir control unit 36 ​​and the ventilation control unit 18 are provided as separate control units. In other embodiments, they may be partially or completely integrated into a single electronic control unit, which then performs some or all of the functions of the control units. The lower section also houses an energy storage unit 74 for supplying the electric and electronic components of the mobile transport device 1. The energy storage unit 74 is preferably designed as a rechargeable battery and preferably has a capacity such that the electric and electronic components can be supplied with electric energy for the entire duration of the transport. The mobile transport device 1 preferably has an electrical connection (not shown) through which the mobile transport device 1 is connected to a local power supply. The mobile transport device 1 can therefore also be operated in stationary mode without the energy storage unit 74 supplying additional energy.

[0126] An outside air fan 46 is disposed in the air intake section 40 of the housing 2 and ventilates air from the environment 44 into the interior 24. In the example embodiment of FIG. 1 , the air intake section 40 opens into the ventilation section 26 of the interior 24, and air from the environment 44 is ventilated into the ventilation section 26. A heating device 50 is disposed in the ventilation section 26, which heats the incoming air. The heating device 50 is disposed so that it can simultaneously heat the air recirculated by the recirculation fan 8.

[0127] An exhaust fan 48 is disposed in the air exhaust section 42 of the housing 2, which directs air from the exhaust section 28 of the interior 24 to the environment 44. Both the outside air fan 46 and the exhaust fan 48 may be controlled by the electronic control unit 10.

[0128] In the example embodiment of Fig. 1, a first insect fattening bin temperature measuring point 56 is arranged in each of the four insect fattening bins 6.1-6.4. In each of the compartments 22.1-22.4 in which the insect fattening bins 6.1-6.4 are accommodated, a first insect fattening bin humidity measuring point 58 is also provided, which is, so to speak, a further insect fattening bin temperature measuring point.

[0129] A storage tank temperature measuring point 62 is arranged in the storage tank 30. A first interior humidity measuring point 64.1 and a first interior temperature measuring point 66.1 adjacent the storage tank exhaust section 34, as well as a second interior humidity measuring point 64.2 and a second interior temperature measuring point 66.2 adjacent the circulation fan 8, are provided in the exhaust section 28. Similarly, a further interior temperature measuring point, CO2 measuring point 72, is arranged in the exhaust section 28 adjacent the exhaust fan 48.

[0130] A third internal temperature measuring point 66.3 and a third internal humidity measuring point 64.3 are arranged in the ventilation section 26. An outdoor humidity measuring point 68 and an outdoor temperature measuring point 70 are arranged outside the housing 2 in the perimeter 44.

[0131] All measuring points are connected to an electronic control unit so that the electronic control unit can analyze the corresponding measuring signals from the measuring points.

[0132] The mobile transportation device 1 is positioned on a pallet 106. This simplifies transportation and the mobile transportation device 1 can be handled and shipped using conventional logistics equipment.

[0133] Fig. 2 shows a side view of a further section of the mobile transport device 1, where the ventilation sections 14.1-14.4 together with the flow cross sections 20.1-20.4 and the storage tank ventilation section together with the storage tank flow cross section 38 can be seen. In the example embodiment of Fig. 2, the flow cross sections 20.1-20.4 and the storage tank flow cross section 38 comprise disks which can be moved by the actuators 21.1-21.4 or the storage tank actuator 39. In the example embodiment of Fig. 2, the actuators 21.1-21.4 are controlled by the ventilation control unit 18 and the storage tank actuator 39 is controlled by the storage tank control unit 36.

[0134] The storage tank flow cross section 38 is completely closed. The first, second and fourth flow cross sections 20.1, 20.2, 20.4 are partially open so that the air from the ventilation section 26 can partially flow into the insect fattening containers 6.1, 6.2, 6.4. On the other hand, the third flow cross section 20.3 is completely open and the air can flow into the third insect fattening container 6.3 via the completely open flow cross section 20.3. As also shown in FIG. 1 by the arrows in the ventilation section 26, the first, second and fourth compartments 22.1, 22.2, 22.4 receive approximately equal air flows, while the third compartment 22.3 receives a slightly higher proportion of air flows. During the breeding phase, as will be explained in more detail, the amount of heat generated by the larvae changes. Typically, it is low at the beginning, then rises after a few days, and eventually falls again towards the end of maturation. This can be explained in particular by frictional heat caused by the larvae rubbing against each other. The individual compartments 22.1 to 22.4 can be ventilated individually, so that the corresponding cohorts of insect larvae present in each compartment 22.1 to 22.4 can be supplied with an appropriate airflow, depending on their individual and maturity level, so as to be able to optimally adjust the environment in each case.

[0135] 3 shows a top view of the mobile transport device 1 with an insulating cover plate 43, which is part of the housing. The selectively openable opening 3 is closed in FIG. 3. The air intake section 40 and the air exhaust section 42 are disposed on the insulating cover plate 43. An outdoor humidity measuring point 68 and an outdoor temperature measuring point 70 are provided in spatial proximity to the air intake section 40, so that the humidity and temperature of the air flowing in through the air intake section 40 can be detected.

[0136] 4 shows a top view of the mobile transport device without the cover plate of the housing 2. The receiving section 4 divides the interior 24 into an exhaust section 28 and a ventilation section 26. The direction of the arrows indicates that a recirculation fan 8 ventilates air from the exhaust section 28 to the ventilation section 26, which can be heated by a heating device 50. CO2 measuring points 60 and also outdoor temperature measuring points are arranged around so that the CO2 concentration can be recorded as well as the humidity and temperature of the incoming air.

[0137] Figure 5 shows the heat release in the different compartments 22.1-22.4 and therefore the curves of the insect larvae cohorts recorded there at different times t1, t2, t3, t4, t5, t6, and t7, which are plotted on the horizontal axis. These time points represent the 1st, 2nd, 3rd, 4th, 5th, 6th, and 7th days of the joint transport of these compartments 22.1-22.4 with the mobile transport device 1. The insect larvae cohorts are of different ages and therefore the individual heat release curves within the compartments 22.1-22.4 are shifted.

[0138] On the vertical axis, the heat output is plotted in watts ranging from 0 to 350W.

[0139] The heat generation in the first compartment 22.1, and thus in the first cohort of insect larvae housed therein, is about 25 watts at time t1, i.e. the first day of transport, and remains approximately constant until time t3. The heat generation increases from time t3, reaching a maximum of about 120 watts shortly before time t6. The heat generation then drops again to about 20 watts by time t7. This heat generation process indicates that the insect larvae picked up in the first compartment 22.2 are relatively young insect larvae at the start of transport.

[0140] The heat generation in the second compartment 22.2, and thus in the second cohort of insect larvae housed therein, is about 10 watts at time t1, rises to about 45 watts by time t3, and then rises to about 120 watts between times t4 and t5. The heat generation then drops to about 10 watts by time t6. The heat generation curves indicate that the insect larvae picked up in the second compartment 22.2 are relatively older than the insect larvae picked up in the first compartment 22.1 at the start of the transport.

[0141] The heat generation in the third compartment 22.3, and thus in the third cohort of insect larvae housed therein, is about 20 watts at time t1, by time t2 the heat generation has already increased to about 50 watts, then between times t3 and t4 it reaches a maximum of about 120 watts. The heat generation then drops to about 10 watts until time t5 and remains constant until time t7. The heat generation curves show that the insect larvae collected in the third compartment 22.3 are relatively older than the insect larvae collected in the first compartment 22.1 and the insect larvae collected in the second compartment 22.2 at the beginning of the transport.

[0142] In the fourth compartment 22.4, the heat output is already about 45 watts at time t1. Between times t2 and t3, the heat output already reaches a maximum of about 120 watts. The heat output then drops to about 10 watts until time t4 and remains constant at about 10 watts until time t7. From this progression, it can be seen that the insect larvae recorded in the fourth compartment 22.4 are the relatively oldest insect larvae at the start of the transport.

[0143] In essence, the curves for the individual compartments therefore show a daily phase shift.

[0144] The heat generated by the insect larvae also generates energy that can be used to heat the circulating air. This can significantly reduce the energy consumption of the energy storage unit 74.

[0145] 5 also shows the progression of the average heat generation 96 with recirculation, achieved via the recirculation fan 8. At time t1, the average heat generation 96 with recirculation is about 20 watts, and at time t2 it is already 50 watts. Between times t3 and t4, the average heat generation 96 reaches a maximum value of about 75 watts and then remains approximately constant at about 75 watts until time t5. The curve of the average heat generation with recirculation then flattens out and drops to about 10 watts by time t7.

[0146] 5 also shows the progression of the total heat dissipation of compartments 22.1-22.4 without recirculation. The total heat dissipation 98 without recirculation is just under 100 watts at time t1, 200 watts at time t2, and then a maximum of about 290 watts at time t3. The progression of the total heat dissipation 98 without recirculation drops to about 260 watts until time t5, and then drops to just over 50 watts until time t7.

[0147] Comparing the average heat generation with recirculation 96 to the total heat generation without recirculation 98 shows that recirculation using recirculation fan 8 results in a reduction in heat generation in mobile transportation device 1.

[0148] FIG. 6 shows the curves of the demand ventilation of the compartments 22.1-22.4, the average demand ventilation 100 with recirculation, and the sum of the demand ventilation 102 of the compartments 22.1-22.4 without recirculation. On the horizontal axis are taken the times t1, t2, t3, t4, t5, t6, and t7, which, as in FIG. 5, represent the 1st, 2nd, 3rd, 4th, 5th, 6th, and 7th days of the joint transportation of these compartments 22.1-22.4 with the mobile transportation device 1. On the vertical axis are taken the curves of the demand ventilation of the compartments 22.1-22.4, the average demand ventilation 100 with recirculation, and the sum of the demand ventilation of the compartments 22.1-22.4 without recirculation. On the horizontal axis are taken the times t1, t2, t3, t4, t5, t6, and t7, which, as in FIG. 5, represent the 1st, 2nd, 3rd, 4th, 5th, 6th, and 7th days of the joint transportation of these compartments 22.1-22.4 with the mobile transportation device 1. On the vertical axis are taken the curves of the demand ventilation of the compartments 22.1-22.4 at 0 m. 3 / h to 20m 3 The required ventilation rate is m / h. 3 The calculated ventilation requirement according to Figure 6 and the calculated heat output according to Figure 5 must be considered together.

[0149] The ventilation requirement for the first compartment 22.1, and therefore for the insect larvae contained therein, is 1 m at time t1. 3 / h, 1m until time t3 3 The ventilation requirement for the first compartment 22.1 initially remains approximately constant at 2 m 3 / h, then between times t5 and t6, 3 / h. The required ventilation volume then increases again to about 1 m 3 / h. The ventilation requirement of the first compartment 22.1 is determined by the heat output of the first compartment 22.1, as shown in FIG.

[0150] The required ventilation rate for the second compartment 22.2 is approximately 0.5 m at time t1. 3 / h, and by time t3, it is 2m 3 / h. Between times t4 and t5, the ventilation requirement of the second compartment 22.2, and therefore of the insect larvae contained therein, increases to a maximum of 7 m 3 / h. By time t6, the required ventilation rate is again about 0.5 m 3 / h and remains constant until time t7. The ventilation requirement of the second compartment 22.2 is determined by the heat output of the second compartment 22.2, as shown in FIG.

[0151] The required ventilation rate for the third compartment 22.3 is 1 m 3 / h or more, and by time t2, 2m 3 / h. 7m 3 A maximum ventilation requirement of 0.5 m3 / h is required between times t3 and t5. Up to time t7, the ventilation requirement of the third compartment 22.3, and thus of the insect larvae contained therein, is approximately 0.5 m3 / h. 3 The required ventilation rate of the third compartment 22.3 is determined by the heat output of the third compartment 22.3, as shown in FIG.

[0152] The fourth compartment 22.4 is already 2m 3The required ventilation volume is already up to 7 m / h between times t2 and t3. 3 / h. Next, the required ventilation volume is about 0.5 m 3 / h and remains constant until time t7. The ventilation requirement of the fourth compartment 22.4 is determined by the heat output of the fourth compartment 22.4, as shown in FIG.

[0153] Again, the curves for the individual compartments essentially show a diurnal phase shift.

[0154] The average required ventilation rate 100 for compartments 22.1-22.4 with recirculation is 1 m 3 Between time t3 and t4, the average ventilation requirement of 100 is 4 m 3 / h, then reaches a maximum value of 4m until time t5. 3 / h. The curve for average demand ventilation 100 with recirculation then flattens out and drops to about 0.5 m by time t7. 3 / h.

[0155] The total required ventilation volume 102 for compartments 22.1 to 22.4 without recirculation is approximately 6 m at time t1. 3 / h, and at time t2, it is about 10m 3 / h, and then at time t3, the maximum is about 17m 3 / h. Up to time t5, the total ventilation requirement 102 without recirculation is initially 16 m 3 / h, then drops to about 3m until time t7. 3 Falls to / h.

[0156] Comparing the average ventilation requirement with recirculation 100 to the sum of the ventilation requirements without recirculation 102, it can be seen that recirculation using recirculation fan 8 results in a lower ventilation requirement for the mobile transportation device 1.

[0157] A mobile transport device 1 according to a second embodiment example of the present invention is shown in Fig. 7. The second embodiment example of the mobile transport device 1 differs from the first embodiment example of the mobile transport device 1 (see Fig. 1) in that the cooling unit 51 is accommodated in a storage container 30. Other features of the second embodiment example of the mobile transport device 1 correspond to those of the first embodiment example of the mobile transport device 1, therefore identical and similar elements are provided with the same reference symbols. In this respect, full reference is made to the above description.

[0158] The cooling unit 51 is and / or includes a cooling body, which may be ice (water), liquid nitrogen (nitrogen ice), solid CO2 (dry ice), a cold compress, e.g. a cool pack, a cooling pad, a Peltier element, a metal and / or ceramic and / or mineral material, or other cooling element, and is configured to cool the insect larvae held in the insect fattening containers 6.1-6.4. The insect larvae may be cooled to such an extent that they are no longer active, i.e. no longer mobile. As long as the insect larvae are held in a cooled state, the heating device 50 is preferably switched off. However, it is possible to heat the insect larvae at any time by using the heating device 50, so that they can be brought back to an active state. The cooling unit may also be or include a cooling unit for active cooling. A cooling unit for active cooling preferably comprises a fan, a pump, and / or a compressor. A cooling unit for active cooling preferably comprises a coolant supply conduit for conducting the coolant, and a coolant discharge conduit for conducting the coolant. Preferably, the coolant supply line and the coolant discharge line are connected via at least a fan, a pump or a compressor, the coolant supply line preferably supplies the coolant to the fan, the pump or the compressor, and the coolant discharge line preferably discharges the coolant from the fan, the pump or the compressor. Preferably, the coolant flows through the cooling unit for active cooling.

[0159] At the first insect fattening vessel temperature measuring point 56 an insect fattening vessel temperature measurement value can be detected. Thus it can be checked whether the temperature in the insect fattening vessels 6.1-6.4 is within a range which keeps the insect larvae cool.

[0160] FIG. 8 shows a schematic flow chart for an example of a first preferred embodiment of a method for transporting insect larvae using a mobile transport device 1, comprising filling a first insect fattening container 6.1 with insect larvae by adding a fattening substrate (step S1), inserting the filled first insect fattening container 6.1 into a receiving section 4 of the mobile transport device 1 (step S2), transporting the insect larvae from a first location to a second location using the mobile transport device 1 (step S3), and removing the first insect fattening container 6.1 from the receiving section 4 at the second location (step S4).

[0161] Figure 9 shows a schematic flow chart for a second preferred embodiment example of a method for transporting insect larvae using a mobile transport device 1, which is a possible improvement of the first embodiment example of a method for transporting insect larvae (Figure 8). During transportation (step S3), this includes providing a signal from the activity sensor device 54 to the electronic control unit 10 (step S3.1.1), determining the activity of the insect larvae (step S3.1.2), and outputting a control signal from the electronic control unit 10 to the recirculation fan 8 based on the determination of step S3.1.2 (step S3.1.3).

[0162] Figure 10 shows a schematic flow chart for a third preferred embodiment example of a method for transporting insect larvae using a mobile transport device 1, which is a possible improvement of the second embodiment example of a method for transporting insect larvae (Figure 9). In addition to the operation of step S3.1.3, this includes the further output of a control signal to the ventilation control unit based on the decision of step S3.1.2 (step S3.1.4).

[0163] Figure 11 shows a schematic flow chart for a fourth preferred embodiment example of a method for transporting insect larvae using a mobile transport device 1, which is a possible improvement of the first, second or third embodiment example of the method for transporting insect larvae (Figures 8, 9, 10). During the transport in step S3, this includes providing a signal from the air sensor device 60 to the electronic control unit 10 (step S3.2.1), determining the air condition of the air circulating in the housing 2 (step S3.2.2), and outputting a control signal from the electronic control unit 10 to the reservoir control unit 36 ​​(step S3.2.3). Steps S3.1.1, S3.1.2, S3.1.3 and S3.1.4, also shown in Figure 10, are optional.

[0164] FIG. 12 shows a schematic flow chart for a fifth preferred embodiment example of a method for transporting insect larvae using a mobile transport device 1, which is a possible improvement of the first, second, third or fourth embodiment example of the method for transporting insect larvae (FIG. 8, FIG. 9, FIG. 10, FIG. 11). During the transport in step S3, this includes providing a signal from the air sensor device 60 to the electronic control unit 10 (step S3.3.1), determining the air condition of the surrounding air (step S3.3.2), and outputting a control signal from the electronic control unit 10 to the heating device 50 (step S3.3.3). Steps S3.1.1, S3.1.2, S3.1.3, S3.1.4, S3.2.1, S3.2.2 and S3.2.3, also illustrated in FIG. 10, are optional.

[0165] FIG. 13 shows a schematic flow chart for a sixth preferred embodiment example of a method for transporting insect larvae using a mobile transport device 1, which is a possible improvement of the first, second, third, fourth or fifth embodiment example of the method for transporting insect larvae (FIG. 8, FIG. 9, FIG. 10, FIG. 11, FIG. 12). During the transport in step S3, this includes providing a signal from the air sensor device 60 to the electronic control unit 10 (step S3.4.1), determining an overshoot of the CO2 concentration measurement (step S3.4.2), and outputting a control signal from the electronic control unit 10 to the outdoor air fan 46 if an overshoot of the CO2 concentration measurement is determined (step S3.4.3), and outputting a control signal from the electronic control unit 10 to the exhaust fan 48 (step S3.4.4). Steps S3.1.1, S3.1.2, S3.1.3, S3.1.4, S3.2.1, S3.2.2, S3.2.3, S3.3.1, S3.3.2, and S3.3.3, also illustrated in FIG. 10, are optional.

[0166] 14A-B show the activity of insect larvae, in particular of the black soldier fly, as they develop, as known from repeated observations of the insect larvae. At the start of the fattening phase, the insect larvae are evenly distributed in the first insect fattening container 6.1 (see FIG. 14A). The insect fattening container is completely filled with fattening substrate (see FIG. 14B).

[0167] As they develop and become more active, the insect larvae crowd into the central section 82 of the insect fattening vessel 6.1 (see FIG. 14C). The fattening substrate gradually dries out and at this point essentially only covers the bottom of the insect fattening vessel 6.1 (see FIG. 14D).

[0168] Figures 14E and 14F show the distribution of insect larvae at the later stages of development. The insect larvae also crowd into the corners of the cubic insect fattening basin 6.1 (see Figure 14E). A side view, such as that shown in Figure 14F, shows that the insect larvae do not crowd flat on the floor, but essentially over the entire height of the insect fattening basin 6.1.

[0169] Fig. 15 shows a stationary insect larvae rearing apparatus 78. A first insect fattening container 6.1, a second insect fattening container 6.2 and further insect fattening containers are arranged in the rearing apparatus. The insect fattening containers are stacked in three vertical rows as shown in Fig. 15.

[0170] An activity sensor device 54 is provided in each of the insect fattening containers 6.1, 6.2, thereby detecting the activity of the insect larvae held in the respective insect fattening container 6.1, 6.2. The measured values ​​recorded by the activity sensor device 54 are provided to the electronic control unit 10 and thus to a processing unit 80 integrated in the electronic control unit 10. Furthermore, the measured data of the air sensor device 60 is provided to the electronic control unit 10, which is able to detect the air conditions both inside and outside the insect larvae rearing apparatus 78. The electronic control unit 10 is also connected to a computer 108, whereby the measured values ​​processed by the processing unit 80 can be displayed to a user.

[0171] Additionally, a circulating fan 8, a heating device 50 and a humidifier 76, which may be controlled by the electronic control unit 10, are disposed within the insect larvae rearing apparatus 78.

[0172] FIG. 16 shows the arrangement of the activity sensor devices 54 in the first insect fattening vessel 6.1. The first insect fattening vessel temperature measuring point 56 and the first insect fattening vessel humidity measuring point 58 are arranged in the central section 82 of the first insect fattening vessel 6.1. The second insect fattening vessel temperature measuring point 88 and the second insect fattening vessel humidity measuring point 84 are arranged close to each other on the side wall of the first insect fattening vessel 6.1. The third insect fattening vessel temperature measuring point 90 and the third insect fattening vessel humidity measuring point 86 are arranged in the corners of the insect fattening vessel 6.1. According to FIG. 16, the second and third insect fattening vessel humidity measuring points 84, 86 also extend over the height of the insect fattening vessel 6.1.

[0173] Based on the observed activity according to Figures 14A-14F, it can be assumed that the insect larvae during their development first swarm at the central section 82, i.e. at the first insect fattening container temperature measuring point 56 and the first insect fattening container humidity measuring point 58, and then additionally at the third insect fattening container temperature measuring point 90 and the third insect fattening container humidity measuring point 86. However, at the second insect fattening container temperature measuring point 88 and the second insect fattening container humidity measuring point, the insect larvae according to Figures 14A-14F do not swarm.

[0174] Figure 17 also shows an arrangement of the activity sensor device 54 in the first insect fattening bin 6.1, but now with sensors instead of measuring points: a first humidity sensor 92.1 is arranged at the first insect fattening bin humidity measuring point 58 (see Figure 16), a second humidity sensor 92.2 is arranged at the second insect fattening bin humidity measuring point 84 (see Figure 16) and a third humidity sensor 92.3 is arranged at the third insect fattening bin humidity measuring point 86 (see Figure 16).

[0175] Further, a first temperature sensor 94.1 is arranged at the first insect fattening container temperature measurement point 56 (see Figure 16), a second temperature sensor 94.2 is arranged at the second insect fattening container temperature measurement point 88 (see Figure 16), and a third temperature sensor 94.3 is arranged at the third insect fattening container temperature measurement point 90 (see Figure 16).

[0176] The sensors 92.1-92.4, 94.1-94.4 supply signals representative of the detected measurements 56, 58, 84, 86, 88, 90 to the electronic control unit 10 and, consequently, to the processing unit 80.

[0177] FIG. 18 shows the curves of measurements recorded by the humidity and temperature sensors as well as the fattening substrate humidity 104 at times t0, t1, t2, t3, t4, t5, t6, t7, t8. The time points are plotted on the horizontal axis. The left vertical axis shows the humidity in percent, ranging from 0% to 120%. The temperature is plotted on the right vertical axis, in degrees Celsius, ranging from 20° C. to 40° C.

[0178] The fattening substrate humidity 104, which may be considered as a reference value for the measured humidity values ​​recorded by the humidity sensor, is 80% at time t1, about 70% at time t4 and 40% at time t7. Thus, between times t1 and t7 the fattening substrate humidity decreases by 40%.

[0179] A first humidity sensor 92.1 (see FIG. 17) arranged in the central section 82 detects a humidity substantially corresponding to the fattening substrate humidity 104 until time t4. From time t4, the humidity detected by the first humidity sensor 92.1 starts to deviate from the fattening substrate humidity 104 and increases to a humidity of 100% by time t7. It can therefore be assumed that insect larvae have swarmed the first humidity sensor 92.1 from time t4, which means that the recorded measurements represent not only the fattening substrate humidity but also the additional humidity of the insect larvae.

[0180] The second humidity sensor 92.2 having the arrangement according to Fig. 17 detects a humidity that substantially corresponds to the fattening substrate humidity 104. It can therefore be assumed that insect larvae do not swarm the second humidity sensor 92.2.

[0181] The third humidity sensor 92.3, having an arrangement according to Fig. 17, detects a humidity that essentially corresponds to the fattening substrate humidity 104 until time t5. Until time t6, the humidity first rises to about 65% and then to 90% until time t7. It can therefore be assumed that insect larvae have swarmed the third humidity sensor 92.3 from time t5, which means that the recorded measurements represent not only the fattening substrate humidity but also the additional humidity of the insect larvae.

[0182] The second temperature sensor 94.2 essentially records a constant temperature of 28°C over times t1-t7. Only at time t4 does the second temperature sensor 94.2 detect a temperature of 30°C.

[0183] The first temperature sensor 94.1 also detects a substantially constant temperature of about 28°C until time t3. The recorded temperature then increases to about 33°C by time t4, and finally to 38°C by time t5. This increase in temperature is due to increased activity of the insect larvae swarming the first temperature sensor 94.1, and an associated increase in heat radiation. The recorded temperature then decreases to about 32°C at times t6 and t7.

[0184] The third temperature sensor 94.3 also detects a substantially constant temperature of about 28°C until time t3. The recorded temperature then rises to about 33°C by time t4, and finally to 38°C by time t5. This increase in temperature is due to increased activity of the insect larvae swarming the third temperature sensor 94.3, and an associated increase in heat radiation. The recorded temperature drops to about 34°C at time t6, then rises slightly to 35°C by time t7.

[0185] FIG. 19 shows a schematic flow chart for an example of a first preferred embodiment of a method for determining insect larvae activity using an insect larvae rearing device 78, which includes filling a first insect fattening container 6.1 with insect larvae by adding a fattening substrate at the start of the fattening phase (step SI) and processing the recorded measurements at a first time t1 using the activity sensor device 54 together with a processing unit 80 (step SII.1). The processing in step SII.1 at time t1 preferably includes the steps of comparing the recorded measurement value with a reference value at time t1 (step A1), determining an undershoot of the reference value at time t1 (step B1), determining an overshoot of the reference value at time t1 (step C1), determining a cluster formation at time t1 (step D1), comparing the cluster formation determined in step D1 with a reference cluster formation at time t1 (step E1), determining a regular activity of the insect larvae at time t1 (step F1), determining an irregular activity of the insect larvae at time t1 (step G1), and outputting a development status signal at time t1 (step H1).

[0186] FIG. 20 shows a schematic flow chart of a second preferred embodiment example of a method for determining the activity of insect larvae, which is a possible improvement of the first embodiment example of the method for determining the activity of insect larvae (FIG. 19).

[0187] In this second preferred embodiment method, the processing at time t1 in step SII.1 is followed by processing measurements recorded by activity sensor device 54 at a second time t2 in step SII.2 by processing unit 80. The processing at time t2 (step SII.2) corresponds to steps A1 to H1, but includes steps A2 to H2 executed for time t2.

[0188] The processing in step SII.2 at time t2 is followed at a third time t3 in step SII.2 by processing measurements recorded by activity sensor device 54 in processing unit 80. The processing at time t3 (step SII.3) corresponds to steps A1-H1 and A2-H2, but includes steps A3-H3 executed at time t3.

[0189] The processing at time t2 in step SII.2 is followed at a third time t3 in step SII.3 by processing the measurements recorded by the activity sensor device 54 in processing unit 80. The processing at time t3 (step SII.3) corresponds to steps A1-H1 and A2-H2, but includes steps A3-H3 executed at time t3.

[0190] The processing at time t3 in step SII.3 is followed at a third time t4 in step SII.4 by processing the measurements recorded by the activity sensor device 54 in processing unit 80. The processing at time t4 (step SII.4) corresponds to steps A1-H1, A2-H2, and A3-H3, but includes steps A4-H4 executed at time t4.

[0191] The processing at time t4 in step SII.4 is followed at a third time t5 in step SII.5 by processing the measurements recorded by the activity sensor device 54 in processing unit 80. The processing at time t5 (step SII.5) corresponds to steps A1-H1, A2-H2, A3-H3, and A4-H4, but includes steps A5-H5 executed at time t5.

[0192] The processing at time t5 in step SII.5 is followed at a third time t6 in step SII.6 by processing the measurements recorded by the activity sensor device 54 in processing unit 80. The processing at time t6 (step SII.6) corresponds to steps A1-H1, A2-H2, A3-H3, A4-H4, and A5-H5, but includes steps A6-H6 executed at time t6.

[0193] The processing at time t6 in step SII.6 is followed at a third time t7 in step SII.7 by processing the measurements recorded by the activity sensor device 54 in processing unit 80. The processing at time t7 (step SII.7) corresponds to steps A1-H1, A2-H2, A3-H3, A4-H4, A5-H5, A6-H6, but includes steps A7-H7 executed at time t7.

[0194] FIG. 21 shows an example of an embodiment of a mobile insect larvae rearing device 110, which can also be used as a mobile transport device 1. This example of an embodiment is based on the example of an embodiment of the mobile insect transport device 1, and elements that are the same and similar to the first example of an embodiment are given the same reference symbols. In this respect, full reference is made to the above description. A first insect fattening container 6.1, a second insect fattening container 6.2 and further insect fattening containers are accommodated in the mobile insect larvae rearing device 110. The insect fattening containers are stacked in two rows, as shown in FIG. 21. An activity sensor device 54 is provided in each of the insect fattening containers 6.1, 6.2. The measured values ​​recorded by the activity sensor device 54 can be supplied to the electronic control unit 10 and to the processing unit 10 integrated therein.

[0195] The energy storage unit 74 is connected to the electronic control unit 10 and supplies it with electrical energy. In the example of the embodiment according to Fig. 21, the heating device 50 is arranged in the lower section of the mobile insect larvae rearing apparatus 110 so that the insect fattening containers 6.1, 6.2 can be positioned above the heating device 50. In the mobile insect larvae rearing apparatus 110, two recirculation fans 8 are also provided for recirculating air in the mobile insect larvae rearing apparatus 110.

[0196] 22 shows a further embodiment example of the mobile insect larvae rearing apparatus 110. In contrast to the embodiment example shown in FIG. 20, four recirculation fans 8 are provided to recirculate the air in the mobile insect larvae rearing apparatus 110.
