Description

Technical Field

[0001] The present application relates to the field of insect breeding equipment, and in particular to a unitized climate control method and device for promoting efficient insect breeding. Background Art

[0002] With the improvement of China's waste sorting system, the demand for the treatment of organic solid wastes such as kitchen waste and livestock manure is increasing day by day. However, the current organic solid waste treatment technologies (incineration, anaerobic fermentation, aerobic fermentation, sanitary landfill, etc.) cannot simultaneously meet the treatment requirements of reduction, harmlessness, and resource utilization. In recent years, the technology of using insects to biologically process organic solid wastes through their digestive tracts has developed rapidly due to its unique advantages in reduction, harmlessness, and resource utilization applications. Among them, the black soldier fly biological conversion technology is the most prominent. There have been some large-scale applications and practices of using black soldier flies to treat organic solid wastes at home and abroad. However, the stable and efficient breeding of black soldier flies has always been one of the bottleneck problems of this technology. At present, the artificial breeding methods of black soldier flies are generally relatively crude, with limitations such as low natural mating rate, great influence by geographical location, season, and weather, low yield of effective fertilized eggs, cumbersome process, and inability to precisely control. In addition, the existing breeding methods and technologies will also cause losses in the actual utilization of eggs due to artificial intervention in related steps, resulting in a decrease in the overall breeding efficiency.

[0003] The stable and efficient breeding of resource insects such as black soldier flies is a prerequisite for large-scale biological conversion of organic solid wastes. At present, the scattered and crude breeding methods and non-systematic breeding facilities have hindered the technical practice application and popularization of large-scale biological conversion of organic solid wastes.

[0004] In the prior art, even though the balance study and corresponding treatment of light and temperature conditions in the breeding process of black soldier fly adults have been carried out to promote the active mating and egg laying of black soldier fly adults, it is difficult to consider the situation of insufficient natural sunlight, and artificial egg collection intervention and cleaning steps are still required. Such breeding means will still affect the actual utilization efficiency of eggs and lead to low overall breeding efficiency. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present application provides a unitized climate control method and device for promoting efficient insect breeding. The present application realizes the regulation of environmental factors required for the complete life cycle of black soldier flies through a sealed chamber, which can effectively improve its breeding efficiency and stably provide the egg production. The present application specifically adopts the following technical solutions.

[0041] An artificial light source 8, which is horizontally arranged at the top of the inner wall of the silo body 2, and is used to supplement the internal lighting requirements of the silo body when natural light is insufficient during the mating stage;

[0042] A nutrient solution spray head 14, which is arranged in the middle of the inner wall of the silo body 2, between the artificial light source 8 and the open receiving port of the hatching box 4 in the tool holder, facing the hatching box directly, and is connected to a nutrient solution tank 18 arranged at the bottom of the device through a nutrient solution pipeline, and is used to spray nutrient solution into the hatching box during the emergence stage, mating stage and hatching stage;

[0043] The atomizing nozzle 13 is rotatably installed in the middle of the inner wall of the bin body 2, and is connected to the water tank 17 arranged at the bottom of the device through a water pipe, and is used to spray disinfectant and clean water into the bin body during the cleaning stage, or spray clean water during the mating stage to keep the humidity in the bin within an appropriate range;

[0044] The air inlet pipe 5 is connected and arranged in the middle of the inner wall of the bin body 2, between the artificial light source 8 and the open receiving port for the holding tool;

[0045] The air outlet pipe 6 is connected and arranged in the middle of the inner wall of the bin body 2, between the artificial light source 8 and the open receiving port for the holding tool, and is diagonally opposite to the air inlet pipe 5;

[0046] The constant temperature and humidity machine 7 is connected to the air inlet pipe 5 and the air outlet pipe 6 at the same time, and is used to adjust the temperature and humidity in the bin body according to the pre-designed plan of the transformation cycle of the insect development stage during the pre-treatment stage, maintain the temperature range in the bin body between 28~30°C and the humidity range in the bin body between 70%~80% during the eclosion stage, maintain the temperature range in the bin body between 32~35°C and the humidity range in the bin body between 85%~90% during the mating stage, and maintain the temperature range in the bin body between 32~35°C and the humidity range in the bin body between 85%~90% during the hatching stage.

[0047] The above device adjusts the temperature and humidity monitor, the air circulation system, the constant temperature and humidity machine 7, the lighting system, the automatic cleaning system and the water tank through the automatic monitoring and control system. Among them, the automatic cleaning system is generally set to have an atomizing nozzle 13 to achieve spraying; the air circulation system has an air inlet pipe 5 and an air outlet pipe 6 connecting each bin body; the lighting system can supplement light through the artificial light source 8 and adjust the external light intensity through the light-shielding curtain 16.

[0048] In the above device, the humidity in the bin body can be jointly adjusted by the constant temperature and humidity machine and the pressurized water pump 19. The start and stop time of the light source is set manually.

[0049] Specifically, the bin body 2 in the above device can be set as a horizontally arranged cylindrical structure, which includes:

[0050] The bin body structure made of materials such as opaque stainless steel, plastic, and aluminum plate. The two side covers of the bin body can be made of glass or acrylic structure, with holes punched in the covers, and the covers can be fixed on the folded edges of the bin body through connecting parts such as bolts. The connecting parts specifically used between the bin body and the cover do not necessarily need to be made of metal materials such as stainless steel, and the same function can also be achieved through snap connection, but it has no impact on the overall breeding device.

[0051] The light-shielding curtain 10 is arranged on the outer layer of the bin body or the cover; the bin body 2 can open its two side covers that can be manually opened and the light-shielding curtain to let in natural light. When the natural light is not enough to provide sufficient illumination, the artificial light source is turned on

[0052] Inner shell 12, which is arranged on the inner wall of the bin body or the cover plate;

[0053] Insulation layer 11, which is arranged between the light-shielding curtain 10 and the inner shell 12;

[0054] The top of the bin body 2 is hoisted and fixed by a support rod, and the side part of the bin body is connected to the main bracket of the device. The support rod is horizontally fixed on the main bracket of the device, and, on the support rod, light-shielding curtains 16 are also hung outside the cover plates at both ends of the bin body;

[0055] Inside the bin body, the containing tool can be matched with the inner wall of the bin body to have an arc-shaped bottom, and the arc-shaped bottom is divided into a pupa box 3 and a spawning and hatching box 4 along the axial direction of the cylindrical structure of the bin body.

[0056] In each bin body, the spawning and hatching box 4 can be set with its opening height higher than that of the pupa box 3 according to the structure shown in Figure 3 The length of the spawning and hatching box 4 along the axial direction of the cylindrical structure of the bin body is less than that of the pupa box 3. Among them, a multi-layer spawning plate 9 is installed in the spawning and hatching box 4;

[0057] The nutrient solution nozzle 14 is arranged above the spawning and hatching box 4 and is used to spray a mixture of kitchen waste leachate and activated Enterococcus faecalis bacterial liquid mixed in a weight ratio of 1% onto the spawning plate 9 arranged in the spawning and hatching box 4 every day in the early stage of the hatching stage after the black soldier fly lays eggs, so that the structure of the spawning plate 9 decomposes naturally, and the eggs then directly hatch naturally in the debris after the decomposition of the spawning plate.

[0058] The above device can be set so that each of its bin bodies independently executes the following steps to independently adjust the temperature and humidity inside the bin body by the constant temperature and humidity machine according to the data of the internal sensors of each bin body, so that the breeding processes between the bin bodies do not interfere with each other, ensuring that the interval time between the newly hatched 1st instar black soldier fly larvae produced in each batch of each bin body is shortened; or, the present application can also set each bin body to carry out black soldier fly breeding according to the following steps at the same time. Each bin body is jointly adjusted by the constant temperature and humidity machine to synchronously adjust the internal temperature and humidity of each bin body, and each bin body synchronously executes the control method from S1 to S6 to obtain a large number of newly hatched 1st instar black soldier fly larvae for biotransformation.

[0059] S1. Pretreatment stage: The pupa box 3 receives and holds black soldier fly prepupae or pupae of appropriate thickness, mixes a small amount of coarse sand, and stirs them evenly. The treated spawning board 9 is placed in the spawning and hatching box 4. The pupa box 3 and the spawning and hatching box 4 are placed in the chamber body 2 together, ensuring that the height of the black soldier fly prepupae or pupae and the coarse sand mixture does not exceed 8 cm, and the weight ratio between the black soldier fly and the coarse sand does not exceed 10:1. According to the pre-designed plan of the insect development stage transition cycle, the constant temperature and humidity machine 7 is set to adjust the environmental temperature in the chamber. For example, in the pretreatment stage, if it is necessary to extend the breeding cycle, the environmental temperature is set to 10 - 15°C and the humidity is between 65 - 75%; if it is necessary to accelerate the breeding cycle, the environmental temperature is set to 25 - 30°C and the humidity is between 75% - 85%. Whether it is necessary to extend or shorten the breeding cycle, a lightless environment needs to be maintained in this stage;

[0060] S2. Emergence stage: The artificial light source 8 is turned off, the light-shielding curtains (10) on both ends of the cover plate (1) are unfolded, and the light-shielding curtain 16 is drawn. The pupa box 3 is kept in the dark state. The constant temperature and humidity machine 7 is set to maintain the environmental temperature in the chamber within the range of 28 - 30°C and the humidity within the range of 70% - 80% for 4 - 7 days. During this period, a small amount of kitchen waste filtrate is sprayed into the spawning box for the adults to absorb naturally;

[0061] S3. Mating stage: The light-shielding curtain 10 and the light-shielding curtain 16 are opened. First, natural light is utilized to maintain 8 hours of natural light irradiation per day, and when the sunlight intensity is less than 10000 lx, the artificial light source 8 with a wavelength range between 450 nm - 570 nm and a color temperature range between 4200 K - 5500 K in the chamber is turned on to supplement the illumination intensity. The constant temperature and humidity machine 7 is set to maintain the environmental temperature in the chamber within the range of 32 - 35°C and the humidity within the range of 85% - 90% for 4 - 5 days. The 8-hour sufficient illumination per day can be ensured by facing the cover plate 1 towards the sun during the period of 8:30 - 16:30 on a sunny day in summer, and this time can be adjusted to 9:00 - 17:00 in winter;

[0062] S4, Incubation stage: Before the black soldier fly lays eggs, a mixture of kitchen waste leachate and activated Enterococcus faecalis bacterial solution is sprayed onto the egg-laying board 9 with a multi-layer structure in the egg-laying and hatching box 4 through the nutrient solution nozzle 14. After the black soldier fly lays eggs, kitchen waste leachate is sprayed every day through the nutrient solution nozzle 14. The constant temperature and humidity machine 7 is set to maintain the internal environment of the chamber within a temperature range of 32 - 35°C and a humidity range of 85% - 90%. During the egg-laying and hatching period, no nutrition is supplied to the adult flies. A large amount of the mixture of kitchen waste leachate and activated Enterococcus faecalis bacterial solution is sprayed onto the egg-laying board 9 by the nozzle 14 to decompose the structure of the egg-laying board 9 naturally, and the temperature and humidity in the chamber are controlled so that the eggs hatch naturally; the egg-laying board 9 is made by mixing wheat bran and corn straw in a volume ratio of 1:1 and pressing them, and it has a structure with several layers stacked overlappingly for adult flies to lay eggs. A gap of 2mm - 4mm is generally reserved between the receiving surfaces of each layer of the board for stacking;

[0063] S5, Treatment stage: After about 8 - 14 days of breeding and hatching process from stage S1 to the end of stage S4, both the intake pipe 5 and the outlet pipe 6 are closed for 12 hours to kill the adult black soldier flies. Then, the pupa box 3 and the egg-laying and hatching box 4 in the containing tool are taken out. After killing the remaining adult flies, eggs, hatched larvae, pre-pupae or pupal cases remaining after eclosion, and the corpses of adult black soldier flies are obtained; the corpses of the insects naturally fall into the pupa box or the egg-laying box and are taken out with the boxes. By the time of taking out, the eggs have hatched into larvae in the egg-laying box. What is taken out from the egg-laying box are the debris after the decomposition of the egg-laying board and the hatched larvae (mixed with some adult fly corpses). What is in the pupa box are the pupal cases and adult fly corpses;

[0064] S6, Cleaning stage: First, the DCW hypochlorous acid solution with a concentration of 500 ppm is sprayed into the chamber in a rotating manner through the atomizing nozzle 13 for disinfection, and then clean water is sprayed into the chamber for cleaning to wash away the remaining adult fly corpses and excreta on the inner wall surface of the chamber.

[0065] In summary, through the regulation of the temperature and humidity environment inside the bin body, the present application realizes a unitized, continuous, and quantitative insect breeding method and its device, which is particularly suitable for the breeding of black soldier flies. In the S1 pretreatment stage of the device: put the appropriate thickness of pre-pupae or pupae of black soldier flies into a storage container and mix them evenly with a small amount of coarse sand; in the S2 eclosion stage: let them stand still for 4-7 days in a constant temperature and humidity dark environment suitable for the eclosion stage until the adults emerge; in the S3 mating stage: in a constant temperature and humidity environment suitable for the survival and reproduction of adults, irradiate with natural light for 8 hours every day to promote their mating. In the S3 mating stage, if the natural light intensity is insufficient, the artificial light source inside the bin can be turned on to supplement the light intensity to promote the mating of black soldier flies; in the S4 egg-laying and hatching stage: place stacked wheat bran boards in the egg-laying area for adults to lay eggs, and directly hatch in the wheat bran scraps; in the S5 larva-taking stage: take out the hatched larvae and the remaining pre-pupae or pupal cases after eclosion; in the S6 cleaning stage: clean the remaining adult corpses and excreta. With the breeding device using this method, the environmental conditions of the whole process of black soldier fly breeding can be accurately regulated through the unitized external closed structure, the automatic monitoring and control system, the air circulation system, the lighting system, and the automatic cleaning system. The present invention can precisely control the breeding behavior of the insect population, shorten the breeding time, reduce manual operations, greatly increase the egg-laying amount, and can continuously and stably produce without being affected by the external environment and regional changes.
