Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of black soldier fly processing equipment, and in particular to a black soldier fly drying, screening and packaging production line. Background Technology
[0002] Black soldier flies can effectively decompose kitchen waste and convert it into high-value biomass such as oil and protein. Using black soldier flies to treat kitchen waste is an environmentally friendly and economically beneficial method. During the black soldier fly breeding process, the insect excrement can be used as biological organic fertilizer. Black soldier fly larvae, due to their high protein content, can be directly fed to poultry and aquatic products or processed into feed additives to replace traditional fishmeal.
[0003] During the processing of black soldier fly larvae, the larvae need to be dried to obtain dried black soldier fly larvae. The dried black soldier fly larvae contain impurities such as broken larvae, frass, and down, so they need to be screened again.
[0004] Among them, Chinese invention patent application with patent number 202411899435.4 and patent title "A Black Soldier Fly Larvae Drying and Sorting Device and Method" specifically discloses a black soldier fly drying and sieving device; the black soldier fly larvae drying and sorting device specifically discloses the following technical solution: a black soldier fly larvae drying and sorting device, including a drying box, a separating device, a recycling device, and an air blowing screening device; the drying box is equipped with a heating device for drying the fresh black soldier fly larvae; the separating device is connected to the outlet end of the drying box and includes a first conveyor belt, on which multiple separators are provided. A plate is provided, and the partition plate and the first conveyor belt do not interfere with each other; a recycling device is connected to the end of the first conveyor belt to receive dried black soldier fly larvae. The recycling device includes a chain-type insect-collecting spoon device, a funnel conveyor component that docks with the chain-type insect-collecting spoon device, and a second conveyor belt located at the bottom of the funnel conveyor component. The dried black soldier fly larvae fall onto the second conveyor belt through the funnel conveyor component and are distributed at intervals on the second conveyor belt; an air blowing screening device includes an air blowing device and an image acquisition device. The image acquisition device is located near one end of the funnel conveyor component, and the air blowing device is fixed to the side of the second conveyor belt. The control system controls the start of the air blowing device according to the image acquisition information.
[0005] It should be noted that the aforementioned black soldier fly larvae drying and sorting device has the following defects, specifically:
[0006] Defect 1: This black soldier fly larvae drying and sorting device can only dry and screen black soldier flies, but cannot package the screened dried black soldier flies, which means it has a relatively limited function.
[0007] Defect 2: Because the dried black soldier fly larvae are at a high temperature after being dried by the drying equipment, the black soldier fly larvae drying and sorting device cannot cool the dried black soldier fly larvae. The dried black soldier fly larvae after drying and screening need to be cooled separately, resulting in low operating efficiency. Utility Model Content

Detailed Implementation
[0033] The present invention will now be described in conjunction with specific embodiments.
[0034] Example 1, as Figure 1 and Figure 2 As shown, a black soldier fly drying, screening, and packaging production line includes a drying component 1, a conveying component, and a screening component 2; wherein the conveying component includes a first conveyor belt 31 and a second conveyor belt 32, and the screening component 2 is a reciprocating screen structure.
[0035] Furthermore, such as Figure 1 and Figure 2 As shown, the black soldier fly drying, screening, and packaging production line also includes a cooling silo 4 and a packaging assembly 5. The cooling silo 4, the first conveyor belt 31, the screening assembly 2, the second conveyor belt 32, and the packaging assembly 5 are arranged sequentially along the conveying direction of the dried black soldier fly larvae.
[0036] Furthermore, such as Figures 4 to 6As shown, the cooling hopper 4 includes a fixed support frame 41 and a main hopper 42 mounted on the upper end of the fixed support frame 41. The main hopper 42 has a vertically penetrating inner cavity 421 formed inside. The upper opening of the inner cavity 421 is the inlet, and the lower opening is the outlet. A vibrating receiving groove 43 is installed on the lower side of the main hopper 42. The vibrating receiving groove 43 is mounted on the fixed support frame 41 through a vibrator 44. The main hopper 42 is surrounded by a... The hopper has a hopper enclosure 45, and a cooling cavity 46 is formed between the hopper enclosure 45 and the main hopper 42, which surrounds the main hopper 42. The side wall of the main hopper 42 is provided with a side wall cooling mesh 422 that connects the cooling cavity 46 and the inner cavity 421 of the hopper. The hopper enclosure 45 is provided with a number of spaced air inlet channels 451 that open outwards. Each air inlet channel 451 is connected to the cooling cavity 46, and each air inlet channel 451 is equipped with an inward-blowing fan 47.
[0037] In addition, packaging component 5 is an automatic bagging and packaging machine.
[0038] In the operation of the black soldier fly drying, screening, and packaging production line in this embodiment, the fresh black soldier fly larvae are first weighed on a rotating weighing tray to quantitatively load them into the material tray 7. After weighing and loading, the material tray 7 containing the fresh black soldier fly larvae is pushed to the drying component 1 by a transfer cart 6 for drying to obtain dried black soldier fly larvae. The dried black soldier fly larvae after drying are poured into the cooling silo 4, where the black soldier fly larvae are cooled at a higher temperature. The dried black soldier fly larvae are cooled and fed to the first conveyor belt 31. The first conveyor belt 31 transports the dried black soldier fly larvae to a reciprocating screen structure, which screens the dried black soldier fly larvae. During this process, the reciprocating screen structure filters out impurities such as broken larvae, frass, and down. The filtered dried black soldier fly larvae enter the second conveyor belt 32. The second conveyor belt 32 transports the filtered dried black soldier fly larvae to an automatic bagging and packaging machine for bagging and packaging.
[0039] It should be emphasized that, for the cooling hopper 4 in this embodiment, the dried black soldier fly larvae with a relatively high temperature are poured into the inner cavity 421 of the hopper through the feed inlet. The dried black soldier fly larvae in the inner cavity 421 are discharged from the discharge outlet at the lower opening of the inner cavity 421 and enter the vibrating receiving trough 43. During this process, the fans 47 in each air inlet channel 451 are started and blow air into the cooling chamber 46 respectively. The cold air entering the cooling chamber 46 enters the inner cavity 421 of the hopper through the side wall cooling mesh 422 of the side wall of the main hopper 42, thereby cooling the dried black soldier fly larvae in the inner cavity 421 to achieve the purpose of cooling the dried black soldier fly larvae. As the vibrator 44 drives the vibrating receiving trough 43 to vibrate, the dried black soldier fly larvae falling into the vibrating receiving trough 43 are vibrated and sent into the first conveyor belt 31.
[0040] In summary, through the above structural design, the black soldier fly drying, screening, and packaging production line of this embodiment can sequentially perform drying, cooling, screening, and bagging operations. Compared with existing technologies, the black soldier fly drying, screening, and packaging production line of this embodiment is more functional and has higher black soldier fly processing efficiency. Therefore, the black soldier fly drying, screening, and packaging production line of this embodiment has the advantages of novel structural design, diverse functions, and high operating efficiency.
[0041] Example 2, as Figure 2 and Figure 3 As shown, the difference between this embodiment 2 and embodiment 1 is that: the first conveyor belt 31 and the second conveyor belt 32 each include a conveyor belt bracket 33, each conveyor belt bracket 33 is rotatably mounted with an active conveyor shaft and a driven conveyor shaft, each active conveyor shaft and the corresponding driven conveyor shaft are respectively wound with a dry insect conveyor belt 34, each conveyor belt bracket 33 is respectively equipped with a drive motor 35 corresponding to the corresponding active conveyor shaft, and each drive motor 35 is respectively driven connected to the corresponding active conveyor shaft.
[0042] The conveying surface of the dried worm conveyor belt 34 is provided with several horizontal bars 341 arranged at intervals along the extension direction of the dried worm conveyor belt 34. The left and right ends of the dried worm conveyor belt 34 are respectively provided with side rails 342 extending along the dried worm conveyor belt 34. The horizontal bars 341, side rails 342 and dried worm conveyor belt 34 are an integral structure.
[0043] During the process of conveying dried black soldier fly larvae via the first conveyor belt 31 and the second conveyor belt 32, the drive motor 35 drives the active conveyor shaft to rotate, and the active conveyor shaft cooperates with the corresponding driven conveyor shaft to drive the dried larvae conveyor belt 34 to move.
[0044] For black soldier fly larvae that fall onto the conveying surface of the dry larvae conveyor belt 34, the crossbar 341, which moves synchronously with the dry larvae conveyor belt 34, is used to scrape the black soldier fly larvae to ensure the stability of the black soldier fly larvae conveying; the side guards 342 located on the left and right ends of the crossbar 341 can effectively prevent the black soldier fly larvae from falling off, thereby further ensuring the stability of the black soldier fly larvae conveying.
[0045] Example 3, as Figure 2 and Figure 3 As shown, the difference between this embodiment 3 and embodiment 2 is that the dry insect conveyor belts 34 of the first conveyor belt 31 and the second conveyor belt 32 are arranged with the front lower and the back higher along the direction of conveying dry black soldier fly larvae, and each conveyor belt support 33 is equipped with a guide wheel group 36 for guiding the movement of the corresponding dry insect conveyor belt 34.
[0046] Example 4, as Figure 6As shown, the difference between this embodiment four and embodiment one is that: an air outlet gap 48 with a downward opening and communicating with the cooling chamber 46 is formed between the lower edge of the hopper enclosure 45 and the lower end of the main hopper 42.
[0047] It should be noted that when the cooling silo 4 is working, the airflow sent downward through the air outlet gap 48 blows towards the vibrating receiving trough 43.
[0048] When the fan 47 delivers cold air into the cooling chamber 46, some of the cold air will be discharged from the air outlet gap 48. The cold air flow discharged through the air outlet gap 48 will further cool the dried black soldier fly larvae in the vibrating receiving trough 43, thereby further improving the cooling effect of the dried black soldier fly larvae.
[0049] Example 5: The difference between Example 5 and Example 1 is that the drying component 1 is a microwave dryer.
[0050] Example 6, as Figure 1 As shown, the difference between this sixth embodiment and the first embodiment is that the black soldier fly drying, screening, and packaging production line includes two cooling silos 4 and two first conveyor belts 31. The two cooling silos 4 are the front silo and the rear silo in sequence, and the two first conveyor belts 31 are the front conveyor belt and the rear conveyor belt in sequence. The front silo, the front conveyor belt, the rear silo, the rear conveyor belt, the screening component 2, the second conveyor belt 32, and the packaging component 5 are arranged in sequence along the conveying direction of the dried black soldier fly larvae.
[0051] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
