Description

Technical Field

[0001] This invention relates to an intensive, three-dimensional, multi-layered insect breeding facility and method, belonging to the field of three-dimensional insect breeding equipment. Background Technology

[0002] Insect farming is a high-yield and cost-effective industry. Insects have short growth cycles, high reproductive capacity, and high feed conversion rates. Compared with traditional animal husbandry, insect farming has a smaller carbon footprint and less environmental impact. Insect farming can reduce greenhouse gas emissions and mitigate climate change; protect biodiversity, reduce deforestation and land degradation; and produce organic fertilizer, improving soil quality. The application of artificial intelligence and automation technologies is making insect farming more efficient and automated. Patent CN120615871 A, invention title: A precision-controlled assembly line-style three-dimensional insect farming system, includes two or more three-dimensional insect farming structures and several layered synchronous feeding and insect-feeding devices. The three-dimensional insect farming structure includes a farming frame and several layers of partitioned continuous farming structures; the partitioned continuous farming structures include a farming space, which is divided into at least two farming zones, each farming zone is equipped with an environmental control mechanism, and at least one farming zone is equipped with a first material loosening mechanism; at least one farming zone has isolation doors at both ends. The system design of this invention adopts a modular concept, and each component can be independently replaced or upgraded to adapt to the special needs of different insect species. Customized breeding of special insects can be achieved by adding environmental control parameters or additional functional modules. This invention proposes the concepts of zoning and segmentation, but its system typically arranges different growth stages within different three-dimensional breeding structures (i.e., different "frames"). Additional conveying devices (such as layered synchronous feeding devices) are needed to connect the structures. This parallel structure and serial process mode increases the horizontal footprint and connection complexity of the equipment, thus increasing investment. Patent CN 208159863U, utility model name: A multi-layer breeding device for raising black soldier flies using livestock and poultry manure, including a frame and multiple layers of conveyor belt mechanisms for breeding black soldier flies. The conveying directions of adjacent conveyor belt mechanisms are opposite, and the livestock and poultry manure conveyed to the end of the conveyor belt mechanism can fall into the next adjacent layer of the conveyor belt mechanism. The conveyor belts on adjacent layers move in opposite directions. The surface layer of livestock manure on the conveyor belts is relatively dry, while the bottom layer is wetter and stickier. When the manure falls from the conveyor belt, the surface layer falls first, followed by the bottom layer. This falling process effectively turns the manure, solving the problem of excessively wet bottom layer manure and manure treatment failure in black soldier fly farming. Although this scheme uses multiple conveyor belts, each layer has the same function, all for full-cycle farming, requiring repeated turning of the material. This uniformly spread pattern fails to differentiate the space and environmental needs of insects at different growth stages, limiting the production capacity per unit area. Therefore, developing a small-footprint, flexible, multi-layered three-dimensional insect farming equipment that can adapt to different insect habits and user needs is of great significance. Summary of the Invention

[0003] This invention provides an intensive, three-dimensional, multi-layered insect breeding facility and method, which solves the problems of existing multi-layered, three-dimensional breeding equipment having a large footprint, high equipment investment, extensive breeding methods, and low efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: An intensive, three-dimensional, multi-layered insect breeding facility includes several insect growth zones and several material conversion zones. The insect growth zones are equipped with at least one larval expansion and breeding layer and at least one larval collection and breeding layer. Both the larval expansion and breeding layer and the larval collection and breeding layer are automatic feeding and discharging structures. The larval collection and breeding layer can realize the temporary storage, resetting, and transportation of materials from the larval expansion and breeding layer and black soldier fly larvae. The larval collection and rearing layer is provided with a collection feed section, a collection rearing section and a collection discharge section in sequence; the larval expansion rearing layer is provided with an expansion feed section and an expansion rearing section, and the discharge end of the expansion rearing section is located above the collection feed section of the larval collection and rearing layer, so that the material can fall into the collection feed section of the larval collection and rearing layer. The material conversion zone is provided with several conversion and aquaculture layers arranged in an alternating pattern and capable of automatic feeding and discharging, as well as a discharge aquaculture layer capable of automatic discharging. The conversion aquaculture layer includes a conversion feeding section and a conversion aquaculture section, and the operating directions of two adjacent conversion aquaculture layers are opposite; The feeding and breeding layer is used to receive materials from the upper conversion and breeding layer, and to breed and / or transport them. The feeding and breeding layer includes a feeding and breeding section and larval feeding sections set at one or both ends of the feeding and breeding section. Isolation doors are provided at both ends of the collecting and breeding section, the expansion and breeding section and the feeding and breeding section.

[0005] Furthermore, preferably: the larval expansion and rearing layer is a zoned continuous rearing facility; and / or the larval collection and rearing layer is a zoned continuous rearing facility.

[0006] Furthermore, preferably: (1) when the number of partitions in the larval collection and rearing layer is less than or equal to the number of partitions in the adjacent larval expansion and rearing layer, and the number of partitions in the larval collection and rearing layer is greater than 1, the larval collection and rearing layer adopts an automatic feeding and discharging structure with forward and reverse rotation to temporarily store, reset and transport materials in the larval expansion and rearing layer and black soldier fly larvae.

[0007] (2) When the number of partitions in the larval collection and breeding layer is greater than the number of partitions in the adjacent larval expansion and breeding layer, or when the number of partitions in the larval collection and breeding layer is 1, the larval collection and breeding layer has a forward-rotating automatic feeding and discharging structure for the temporary storage, resetting and conveying of materials in the larval expansion and breeding layer and black soldier fly larvae.

[0008] Furthermore, preferably, the aforementioned expansion and breeding section, collection and breeding section, and conversion and breeding section are sealed structures.

[0009] Furthermore, preferably, the feeding and aquaculture layer is a bidirectional, automatic feeding and discharging structure.

[0010] Furthermore, preferably: the insect growth zone is one or two; and / or the material conversion zone is one to three.

[0011] Furthermore, preferably: the insect growth area is provided with 1-3 larvae expansion and rearing layers and 1 larvae collection and rearing layer; the material conversion area is provided with 2-3 alternating conversion and rearing layers that can automatically feed and discharge materials, and 1 material discharge and rearing layer that can automatically feed and discharge materials.

[0012] Furthermore, preferably: the larval expansion and rearing layer is a zoned continuous rearing facility divided into 1-3 zones; And / or the larval collection and rearing layer is a continuous rearing facility with 1-2 zones.

[0013] This invention also provides a continuous automated insect rearing method, employing an intensive, three-dimensional, multi-layered insect rearing structure, comprising the following steps: S1. Initialization and Cycle Start-up: In the initial cycle, insect eggs or larvae and materials are sequentially introduced into the larval expansion and rearing layer according to a predetermined time sequence. By controlling the movement of each rearing layer, the insects and materials are sequentially transferred between the larval expansion and rearing layer, the larval collection and rearing layer, the conversion and rearing layer, until each rearing layer is filled with insects and materials at different growth stages, thus completing the system startup. S2. Continuous Production Cycle: On each production day after startup, perform the following operations: a) Introduce new insect eggs or larvae and materials at the input end of the larval expansion culture layer; b) Synchronously control the movement of each breeding layer so that the insects and materials in the last section of the larval expansion breeding layer are transferred to the larval collection breeding layer, and the insects and materials in each section of the larval collection breeding layer, the conversion breeding layer and the discharge breeding layer are transferred to the next section or the next breeding layer. c) At the output end of the feeding and breeding layer, collect insects that have reached the harvest standard, residual materials, and insect sand; By controlling the movement sequence of each breeding layer, the feeding in step a), the material flow within the system in step b), and the harvesting in step c) are carried out continuously and synchronously every day, realizing continuous automatic feeding and harvesting of insects every day.

[0014] The beneficial effects of this invention are: This invention separates and professionally designs the two core functions of the breeding process—insect biomass propagation (growth zone) and material degradation and transformation (conversion zone)—in vertical space. The growth zone focuses on the rapid growth of larvae, providing a structure with precise environmental control and compact space. The conversion zone focuses on the rapid growth of insects and the transformation of materials. The materials automatically fall and turn over between adjacent conversion and breeding layers, perfectly solving the problems of material compaction, uneven humidity, and insufficient oxygen supply. This creates an optimal feeding environment for insects (such as black soldier flies) without the need for additional turning and turning equipment. This specialized division of labor avoids the design compromises caused by functional mixing, maximizes the space utilization efficiency of each area, thereby achieving higher production capacity within a smaller total footprint and reducing overall building and equipment investment.

[0015] In this invention, the discharge end of the larval expansion and rearing layer is located directly above the feed section of the larval collection and rearing layer. The material from the conversion rearing layer ultimately flows into the discharge rearing layer, effectively solving the problem of the independent and bulky external material distribution and insect feeding device required in CN120615871A. The transfer of material and insects is automatically completed through the built-in structure of the equipment, realizing true assembly line production, greatly improving the continuity and stability of the system, while significantly reducing equipment complexity and external transportation costs.

[0016] This invention organically combines three technologies—functional zoning, vertical assembly line, and built-in feed turning—to construct a highly compact, continuous, and efficient aquaculture system. It fundamentally solves the prominent contradictions of traditional three-dimensional aquaculture equipment in terms of land area, investment, automation level, and aquaculture effect, and has strong practicality and applicability.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are also described.

[0020] like Figure 1 As shown, an intensive three-dimensional multi-layer insect breeding structure includes several insect growth areas and several material conversion areas. The insect growth area is provided with at least one larval expansion and breeding layer 11 and at least one larval collection and breeding layer 12. Both the larval expansion and breeding layer 11 and the larval collection and breeding layer 12 are automatic feeding and discharging structures. The larval collection and rearing layer 12 is used for the early expansion and / or collection of larvae, providing highly active larval seedlings for subsequent conversion. It is provided with a collection and feeding section 123, a collection and rearing section 122, and a collection and discharging section 121 in sequence. The function of the larval expansion and rearing layer 111 is to expand the larvae in the early stage and provide highly active larvae for the later conversion material. It is equipped with an expansion feeding section 11 and an expansion rearing section 112. The discharge end of the expansion rearing section 112 is located above the collection feeding section 123 of the larval collection rearing layer 12, so that the material can fall into the collection feeding section 123 of the larval collection rearing layer 12. The material conversion zone is provided with several conversion and aquaculture layers 13 arranged in an alternating manner and capable of automatic feeding and discharging, and a discharge aquaculture layer 14 capable of automatic discharging. The conversion and rearing layer 13 mainly digests the insect seedlings and converts them into insect protein. It includes a conversion feeding section 131 and a conversion rearing section 132. The two adjacent conversion and rearing layers 13 run in opposite directions. The discharge breeding layer 14 is used to receive materials from the upper conversion breeding layer 13 and to breed and / or transport them. The discharge breeding layer 14 includes a discharge breeding section 142 and larval discharge sections 141 set at one or both ends of the discharge breeding section 142. Isolation doors are provided at both ends of the collection breeding section 122, the expansion breeding section 112, the conversion breeding section 132 and the discharge breeding section 142.

[0021] The larval expansion and rearing layer 11 is a zoned continuous rearing structure, generally using 1-3 zones. The larval collection and rearing layer 12 is also a zoned continuous rearing structure, generally using 1-2 zones. The number of zones can be reasonably set according to the rearing time of different insect larvae, ensuring that the total time spent in the larval expansion and rearing layer 11 and the larval collection and rearing layer 12 is not less than the insect expansion and rearing time. The zoned continuous rearing structure is existing technology, and can be referred to in application number 2025109034158, invention title: A Zoned Continuous Rearing Structure and its Rearing System; further details are omitted.

[0022] The expansion and rearing section 112, the collection and rearing section 122, and the transformation and rearing section 132 serve as growth and development areas for insect larvae. Sealing or non-sealing can be chosen based on different raw materials and the insects' living habits. Generally, if exhaust gas treatment is not required during production, a sealed structure is unnecessary; otherwise, a tightly sealed structure is typically used. Sealing structures are conventional technologies; individual sealing of each layer or overall sealing can be employed, depending on the specific circumstances.

[0023] The feeding and aquaculture layer 14 can adopt a single-line movement feeding and discharging mechanism or a bidirectional movement automatic feeding and discharging structure as needed. In the embodiment of the present invention, a bidirectional movement automatic feeding and discharging structure is adopted.

[0024] The number of insect growth zones and material conversion zones determines the processing capacity of the equipment. The appropriate number can be selected according to the different growth habits of insects, the amount of material to be processed, and the user needs. They can then be stacked for processing. Generally, the number of insect growth zones is 1 or 2, and the number of material conversion zones is 1-3.

[0025] The number of larval expansion and rearing layers 11 and conversion rearing layers 13 is selected appropriately according to the different growth habits of insects, material processing volume and user needs. Generally, the insect growth area has 1-3 larval expansion and rearing layers 11 and 1 larval collection and rearing layer 12, and the material conversion area has 2-3 conversion rearing layers 13 arranged in an alternating manner and capable of automatic feeding and discharging, as well as 1 discharging rearing layer 14 capable of automatic feeding and discharging.

[0026] Other components of the intensive three-dimensional multi-layer insect breeding structure of this invention are existing technologies, such as the frame, ventilation mechanism, and exhaust gas treatment mechanism. For details, please refer to the following related technologies: Application No. 202510903409.2, Invention Title: A Precision Control Flow Line Three-Dimensional Insect Breeding System; Application No. 2025109034158, Invention Title: A Zoned Continuous Breeding Structure and Breeding System Thereof; Application No. 2025120351263, Invention Title: A Micro-Powered Disassembly and Assembly Type Three-Dimensional Continuous Insect Breeding System.

[0027] The following uses black soldier fly larvae farming as an example to specifically illustrate the farming process of different devices in this invention. The larval expansion stage of black soldier fly larvae farming takes 4 days, and the transformation stage takes 3-4 days. A feeding cart 15 is used for larval collection, feeding, and feeding operations. The feeding cart 15 is prior art; for its specific structure, please refer to application number 2025213704552, invention title: A Layered Synchronous Feeding and Feeding Device, which will not be described in detail here.

[0028] Example 1 like Figure 1 As shown, an intensive three-dimensional multi-layer insect breeding structure includes an insect growth area and a material conversion area. The insect growth area is provided with a larval expansion and breeding layer 11 and a larval collection and breeding layer 12. The larval expansion and breeding layer 11 is a forward-moving, partitioned continuous breeding structure with two partitions. The larval collection and breeding layer 12 is a forward-and-reverse moving, partitioned continuous breeding structure with two partitions.

[0029] The material conversion zone has two staggered conversion and rearing layers 13 with automatic feeding and discharging capabilities, and one discharge rearing layer 14 with automatic discharging capability; the discharge rearing layer 14 has an automatic feeding and discharging structure that moves in both directions. There are 5 rearing layers, and the rearing length of the material conversion zone is twice the length of the 11 larval rearing layers, with a rearing cycle of 7 days.

[0030] The operation process of this embodiment: On the first day, in the first section of the larval expansion and rearing layer 11, black soldier fly eggs (or larvae) and materials were introduced using a feed cart 15, and environmental conditions were controlled for rearing. On the second day, the larval expansion culture layer 11 was moved so that the black soldier fly larvae and materials in the first section were moved to the second section. New black soldier fly eggs (or larvae) and materials were introduced into the first section, and the environmental conditions were controlled for culture. Day 3: Simultaneously move the larval expansion and rearing layer 11 and the larval collection and rearing layer 12, so that the black soldier fly larvae and materials in the second section of the larval expansion and rearing layer 11 fall into the collection and feeding section 123 of the larval collection and rearing layer 12 under the action of gravity, and are then transported to the first section of the larval collection and rearing layer 12. At the same time, repeat the operation of Day 2. Day 4: Repeat the operation of Day 3, so that the larvae collect the material in Zone 1 of the rearing layer 12 and move the larvae to Zone 2; Day 5: Black soldier fly larvae propagation is completed. First, move the larvae collection and cultivation layer 12 forward, and use the material distribution vehicle 15 to collect the black soldier fly seedlings and materials in the second section of the larvae collection and cultivation layer 12 through the collection and discharge section 121. Then, transport the black soldier fly larvae and materials in the first section to the second section for temporary storage. New materials are fed into the feeding cart 15, and the first conversion and breeding layer 13 is started at the same time. Black soldier fly larvae and materials are fed into the first conversion and breeding layer 13 for conversion and breeding. When feeding, the first conversion and breeding layer 13 and the larval collection and breeding layer 12 can be started simultaneously. By controlling the rotation speed of the first conversion and breeding layer 13 and the larval collection and breeding layer 12, the feeding of materials by the feeding cart 15 and the discharge of materials by the larval collection and breeding layer 12 are synchronized, and the black soldier fly larvae and materials are directly fed into the first conversion and breeding layer 13. After the cloth is used to feed the insects, the larvae collection and rearing layer 12 is moved in the opposite direction, so that the material and larvae in the second section of the larvae collection and rearing layer 12 are moved to the first section, and the second section is left empty. Then the operation on the fourth day is repeated. Day 6: Simultaneously start the first and second conversion breeding layers 13, and transport the black soldier fly larvae and materials in the first conversion breeding layer 13 to the second conversion breeding layer 13. At the same time, repeat the operation of day 5. Alternatively, the operation of day 5 can be repeated asynchronously. New materials are put into the material distribution vehicle 15 to distribute the material in the second conversion breeding layer 13. After the distribution operation is completed, repeat the operation of day 5 separately. Day 7: Simultaneously start the first conversion and breeding layer 13, the second conversion and breeding layer 13, and the discharge breeding layer 14 to realize the transportation of black soldier fly larvae and materials between the first conversion and breeding layer 13, the second conversion and breeding layer 13, and the discharge breeding layer 14. At the same time, repeat the operation of day 5. After 7 days, each layer of the intensive three-dimensional multi-layer insect breeding mechanism of this equipment has materials and black soldier fly larvae, and the equipment start-up is completed. Of course, it is also possible to adopt the bottom-up sequence, by starting the automatic feeding and discharging of adjacent two layers in turn, so that the black soldier fly larvae and material conveyor belts can be laid at the same time. Day 8: After seven days of breeding, the black soldier fly larvae reach the collection and separation standard. Start the drying equipment of the feeding breeding layer 14 to dry the black soldier fly larvae, remaining materials and insect sand. Then start the feeding breeding layer 14 again and repeat the operation of day seven. This will enable continuous breeding with daily feeding and daily larvae output.

[0031] The method of the present invention uses a single material feeding cart 15 to display material collection, feeding, insect feeding and feeding operations at different stages. At the same time, the black soldier fly larvae raised in the breeding area of ​​the larval collection breeding layer 12 of the present invention can be used as seedlings for the two-layer conversion breeding layer 13. The equipment has a small footprint and low investment.

[0032] Example 2 like Figure 2 As shown, an intensive, multi-layered, three-dimensional insect breeding structure is basically the same as in Example 1, except that the conversion breeding layer 13 in this example has three layers, and the breeding cycle is 8 days. Figure 2 It can be seen that, to address the different material conversion days for different insects, the conversion time can be controlled by adjusting the number of layers in the conversion rearing layer 13. The rearing layer consists of 6 layers, the rearing length of the material conversion zone is twice the length of the larval expansion rearing layer 11, and the rearing cycle is 8 days.

[0033] Example 3 like Figure 3 As shown, an intensive, three-dimensional, multi-layered insect breeding facility includes an insect growth zone and a material conversion zone. The insect growth zone has one larval expansion breeding layer 11 and one larval collection breeding layer 12. The larval expansion breeding layer 11 is a forward-moving, zoned, continuous breeding mechanism with three zones. The larval collection breeding layer 12 is a forward-moving, zoned, continuous breeding mechanism with one zone. The material conversion zone has two staggered, automatically feeding and discharging conversion breeding layers 13 and one automatically discharging discharging breeding layer 14. The discharging breeding layer 14 is an automatically feeding and discharging structure that moves in both directions. The number of breeding layers is 5. The breeding length of the material conversion zone is 3 times the length of the larval expansion breeding layer 11 zones, and the breeding cycle is 6 or 7 days.

[0034] The breeding process in this embodiment is basically the same as that in embodiment 1. The difference is that the larval collection and breeding layer 12 is a forward-moving, partitioned, continuous breeding mechanism with only one partition. Therefore, the breeding area has enough space to store black soldier fly larvae and materials. Thus, it is not necessary to use the reverse material reset method to achieve synchronous operation of the larval expansion breeding layer 11 and the larval collection and breeding layer 12.

[0035] In this embodiment, the larval collection and rearing layer 12 can be used as a separate material conveying device, or as a rearing and conveying device for black soldier fly larvae and materials, thus enabling the insect rearing period to be 6 or 7 days.

[0036] like Figure 4 As shown, with Figure 3 The basic structure is the same, except that the material conversion zone has three staggered conversion and breeding layers 13 that can automatically feed and discharge materials. The number of breeding layers is 6, the breeding length of the material conversion zone is 3 times the length of the larval expansion breeding layer 11, and the breeding cycle is 6 or 7 days.

[0037] Depend on Figure 3 and 4 It is understood that the insect breeding facility of the present invention can adjust the number of breeding days by adjusting the number of partitions in the larval expansion breeding layer 11 and the larval collection breeding layer 12.

[0038] Example 4 like Figure 5 As shown, an intensive, multi-layered, three-dimensional insect farming structure includes one insect growth zone and two material conversion zones. The insect growth zone has two larval expansion and rearing layers 11 and one larval collection and rearing layer 12. The larval expansion and rearing layers 11 are forward-moving, zoned, continuous rearing structures with three zones. The larval collection and rearing layer 12 is a forward-moving, zoned, continuous rearing structure with one zone. The material conversion zone has two staggered, automatically feeding and discharging conversion rearing layers 13 and one automatically discharging discharge rearing layer 14. The discharge rearing layer 14 is an automatically feeding and discharging structure that moves in both directions. There are nine rearing layers. The rearing length of the material conversion zone is three times the length of each zone in the larval expansion and rearing layers 11. The rearing cycle is 6 or 7 days. Figure 6 As shown, an intensive, three-dimensional, multi-layered insect breeding facility, and Figure 5 They are basically the same, with the following differences: there are 3 material conversion zones and 3 larval expansion and rearing layers 11. The number of rearing layers is 13, the rearing length of the material conversion zone is 3 times the length of the larval expansion and rearing layer 11, and the rearing cycle is 6 or 7 days.

[0039] like Figure 7 As shown, an intensive, three-dimensional, multi-layered insect breeding facility, and Figure 5The basic structure is the same, except that the material conversion zone has three staggered conversion and breeding layers 13 that can automatically feed and discharge materials. The number of breeding layers is 11, the breeding length of the material conversion zone is three times the length of the 11 larval expansion breeding layers, and the breeding cycle is 7 or 8 days.

[0040] like Figure 8 As shown, with Figure 7 They are basically the same, with the following differences: there are 3 material conversion zones and 3 larval expansion and rearing layers 11. The number of rearing layers is 16, and the rearing length of the material conversion zone is 3 times the length of the larval expansion and rearing layer 11. The rearing cycle is 7 or 8 days.

[0041] Depend on Figure 5-8 It is understood that the present invention can adjust the length, height and breeding time of the breeding equipment by adjusting the number of layers and partitions of the larval expansion and breeding layer 11 and the number of material conversion zones, thus adapting to the applicability of equipment with different space sizes.

[0042] Example 5 like Figure 9 As shown, an intensive, multi-layered, three-dimensional insect farming structure includes one insect growth zone and two material conversion zones. The insect growth zone has three larval expansion and rearing layers 11 and one larval collection and rearing layer 12. The larval expansion and rearing layer 11 is a forward-moving, zoned, continuous rearing structure with one zone. The larval collection and rearing layer 12 is a forward-moving, zoned, continuous rearing structure with one zone. The material conversion zone has two staggered, automatically feeding and discharging conversion rearing layers 13 and one automatically discharging discharge rearing layer 14. The discharge rearing layer 14 is an automatically feeding and discharging structure that moves in both directions. The number of rearing layers is 10. The rearing length of the material conversion zone is twice the length of the larval expansion and rearing layer 11 zones, and the rearing cycle is 7 days.

[0043] The breeding process is basically the same as in Example 1, except that the larvae are collected from the black soldier fly seedlings in the breeding layer 12 as seedlings for the two material conversion zones.

[0044] like Figure 10 As shown, with Figure 9 They are basically the same, except that the material conversion zone has three staggered conversion and aquaculture layers 13 that can automatically feed and discharge materials.

[0045] like Figure 11 As shown, with Figure 9 The basic structure is the same, with the main difference being that there are three material conversion zones. The number of rearing layers is 13, and the rearing length of the material conversion zone is three times the length of the 11th larval rearing layer. The rearing cycle is 7 days. When introducing the larvae, the larvae collect black soldier fly seedlings from rearing layer 12 as seedlings for the three material conversion zones.

[0046] Example 6 like Figure 12 As shown, an intensive, three-dimensional, multi-layered insect breeding facility includes two insect growth zones and three material conversion zones. The insect growth zones have one larval expansion breeding layer 11 and one larval collection breeding layer 12. The larval expansion breeding layer 11 is a forward-moving, zoned, continuous breeding mechanism with one zone. The larval collection breeding layer 12 is also a forward-moving, zoned, continuous breeding mechanism with one zone. The material conversion zones have two staggered, automatically feeding and discharging conversion breeding layers 13, and one automatically discharging discharging breeding layer 14. The discharging breeding layer 14 is an automatically feeding and discharging structure that moves in both directions. There are 13 breeding layers. The breeding length of the material conversion zone is three times the length of the larval expansion breeding layer 11, and the breeding cycle is 7 days.

[0047] The breeding process is basically the same as in Example 1, except that: on odd-numbered days, one insect growth zone is rotated and circulated, and on even-numbered days, another insect growth zone is rotated and circulated. The larvae collect black soldier fly seedlings from the breeding layer 12 as seedlings for the three material conversion zones. This operation can change the breeding time of black soldier fly larvae and avoid excessive breeding, which would affect the reproduction of black soldier fly larvae.

[0048] like Figure 13 As shown, with Figure 12 The difference lies in the fact that the material conversion zone has three staggered conversion and breeding layers 13 that can automatically feed and discharge materials. The number of breeding layers is 16, the breeding length of the material conversion zone is 3 times the length of the larval expansion breeding layer 11, and the breeding cycle is 8 days.

[0049] Depend on Figure 12 and 13 We can see that we can control the insect breeding time by adjusting the insect growth area.

[0050] In this invention, the insect growth zone and the material conversion zone are generally positioned such that the insect growth zone is above the material conversion zone and is vertically arranged.
