Description

Apparatus for treatment of organic waste using BSF larva}

The present invention relates to an organic waste treatment apparatus using insect larvae, and more particularly, to an organic waste treatment apparatus using black soldier fly (BSF) larvae.

At present, organic waste such as food waste emitted from homes and restaurants, organic waste generated from industrial sites, and livestock waste and phosphorus from livestock houses can cause serious environmental problems such as soil and rivers if discharged without treatment.

According to the conventional method, a method of recycling organic waste to livestock feed or compost through a specific treatment process, a method of landfilling or dumping at a certain area is mainly used. In this case, there is a problem that the economic efficiency is low in terms of installation cost and maintenance cost of the processing device. In addition, when the discharge is used as feed, side effects such as mass generation are large, and composting has problems such as reheating and ineffective imbalance.

In order to solve the above problems, organic waste treatment systems have been developed using living organisms such as earthworms and fly larvae. Also, in this case, the discharged fecal soil is excellent in inefficiency, so it can be usefully used for cultivating farmland, horticulture, orchard, etc., and it is known that it plays a role in increasing the growth of plants and the yield of products.

Of these, Dongae et al, the length of the eggs to adults is 37 to 41 days, the larvae that act as a decomposer is about 14 days. After a period (about 14 days) when the organic larvae can decompose organic waste, the larvae crawl out to find a dry place to become a pupa. Injecting 5000 larvae into Dongae, etc. in 10 kg of food waste decomposed more than 80% of the food waste in 5 days, and the decomposed food waste was reduced by about 42% in volume and about 70% in weight. It is much more effective to breed and use Dongae et al. Because larvae have longer time to decompose organic waste resources than earthworms or house flies.

However, the organic waste treatment apparatus using an earthworm or a fly has problems such as being applied only to a small amount of organic waste generated at home, odor generated when organic waste decays, and difficulty in separating feces and larvae.

Therefore, larvae in Dongae, etc. can not only process organic waste, but also can be used as animal feed and oil extraction, it is necessary to develop a homeless larvae automatic collection device that can efficiently breed and grow it. Therefore, there is a need for an automated processing device that can effectively reduce the labor force by developing a larva automatic breeding device in Dongae, etc., which can effectively breed larvae in Dongae, and automatically collect homeless larvae.

The present invention provides a breeding container and a device in Dongae, which can breed large quantities of larvae indoors and outdoors in Dongae, which can environmentally decompose organic wastes discharged from homes, livestock farms, cafeteria, and the like.

1 to 3 to describe the organic waste treatment container according to an embodiment of the present invention.

Referring to Figure 1, the container body 120 is covered by a container cover that can open and close the upper surface of the container body. The container cover may include a cover rib 110 connecting the cover body network 100 and the edge or the center of the container cover. The container cover may enable the air flow to the outside while protecting the larvae and the larvae that are bred in the interior of the container body 120 from the outside using the cover network 100. According to another embodiment, the container cover does not include the cover network 100, it may be formed in a completely sealed form. In addition, the container cover may serve to protect the larvae and organic waste from external animals, such as dongae inside the container body 120, regardless of its shape. For example, the container cover may be a mesh.

In addition, according to another embodiment, the container cover may be formed in a shape capable of preserving the temperature and humidity inside the container body 120. For example, because the larvae dongae nutrients enough nutrients after the pupae to go dry and cool conditions to move to find the larvae in order to collect the larvae in a quick time, the container body with a closed front cover 120 may be covered. If the cover of the container at the time when the larvae pupae in the Dongae lamp, the temperature and humidity inside the container body 120 rises so that the larvae in Dongae lamp can be collected faster through the inclined surface (123). For example, the container cover may be formed of vinyl, plastic, iron plate, stainless steel, or the like.

The container body 120 is formed with an inclined surface on one or more sides, there is provided a space in which larvae inhabit such as Dongae. In dongae, larvae tend to find high dry conditions before moving to sloping high places. In order to use this property, the container body 120 has an upper surface open, and the inclined surface 123 is formed on at least one side surface so that the larvae can rise before the pupa, which has sufficiently taken nutrients from organic waste. Organic waste can be collected as fecal soil if it is sufficiently decomposed by larvae, etc. after injection.

Referring to FIG. 2, the interior of the container body 120 is shown so that the inclined surface 123, the non-inclined surface 126, the lateral open surface 135, and the lower open surface 137 can be seen.

The number of inclined surfaces 123 is related to the number of side surfaces of the container body 120 and is not particularly limited. For example, when the side of the container body 120 has four, the number of the inclined surfaces 123 may be four or less. In addition, when the container body 120 has a small volume so that it can be utilized in a small space, if the inclined surface 123 is large, the width of the upper surface of the container body 120 becomes relatively large, the number of the inclined surface 123 is 1 Or two. When the number of the inclined surfaces 123 is two, the inclined surfaces 123 may be disposed to face each other.

Here, the angle formed between the inclined surface 123 and the bottom of the body portion may be an angle at which the larvae can move to the Dongae and the like along the inclined surface 123. For example, the angle of inclination may be 10 ° to 80 ° to allow efficient collection without steep to allow the larvae to climb on the dongae. Looking at the collection amount, advantages and disadvantages of larvae in accordance with the angle formed between the inclined surface 123 and the bottom of the main body as follows. If the angle is small, it can collect a large amount of larvae, but it takes a lot of place because a large container is required.

Table 1. Larvae collection, advantages and disadvantages according to tilt angle

Referring to Table 1, when the angle is 80 ° or less, the collection amount is rapidly increased to 88%, and when the collection amount is 70 ° or less, it becomes 90% or more. Accordingly, when the angle of the inclined surface 123 is set to 10 ° to 80 °, larvae can be efficiently collected in terms of collection amount and volume.

Collecting unit 130 is formed on the outer side of the inclined surface of the container body 120, collects the larvae in Dongae. The collecting unit 130 has a side open surface 135 connected to the inclined surface 123 so that the larvae are collected on the same or the like moving through the inclined surface 123 of the container body 120 is larger than the lower open surface 137. It may have an inclined tapered shape.

In addition, according to another embodiment of the present invention, the inclined inclined groove (not shown) may be formed on the non-inclined side of the container body 120, not the inclined surface. When the inclined groove is formed in the inclined groove and the lateral opening surface 135 in the upper portion of the non-inclined side of the container body 120 to reach the lateral opening surface of the collector 130 in the Dongae, etc. moved through the inclined groove. Side upper grooves (not shown) to be connected may be formed.

In addition, according to another embodiment of the present invention, the organic waste treatment apparatus may be a device capable of breeding Dongae, etc. in a large capacity in a wide place, such as a road surface, a warehouse, a plastic house. In this case, the inclined groove inclined to the non-inclined side may be formed on the side of the breeding device. The larvae in Dongae, etc. can be collected in a separate collecting container after moving upwards through the inclined surface and the inclined groove. The larvae on the dongae moved upward through the inclined groove can move to the collecting unit 130 via the side upper groove formed on the upper side.

Referring to Figure 3 describes the procedure of collecting larvae Dongae, as follows.

First, the larvae 310 are introduced into Dongae and the like on the upper portion of the organic waste 320 accommodated in the container body 120 by the user. The larvae 310 in Dongae, etc. move along the inclined surface 123 to become a pupa after decomposing the organic waste 320. The caterpillar 310 is then collected downward through the lower opening surface 137 in the dongae, such as the dongae passed through the side opening surface 135 of the collecting unit 130 at the top of the inclined surface 123.

In addition, according to another embodiment of the present invention, a heater (not shown), a temperature sensor (not shown), a cooling unit (not shown), may further include a temperature blocking film (not shown).

The heater is attached to the side of the container body 120 to increase the edge temperature of the container body 120 cooled by the ambient temperature. To explain the need for this, the larva 310 in Dongae etc. is active even at 50 ° C to 60 ° C, but most actively live before or after 35 ° C to 45 ° C. When the temperature rises to about 50 ° C., the larvae 310 in the dongae tend to move to the side of the container body 120, which is an external access point having a low temperature, which is a good point to act.

The external access point is in contact with the outside and thus forms a relatively low temperature. When the larvae 310 move to the external access point in the Dongae etc. may move to the lateral opening surface 135 may cause a problem that the ratio is collected in the collecting container is reduced. Therefore, the heater raises the temperature of the external access point to block the caterpillar 310 from coming to this point. The heater may be attached to the whole or continuously around the inside or outside of the container body 120 in a continuous shape, or may be partially attached.

Such a heater may be adjusted to the temperature of the container body 120 because the ambient environment is below freezing in the winter and the larvae 310 may not be active in Dongae and the organic waste treatment.

In addition, the temperature blocking film may be attached to prevent the inside of the container body 120 from being affected by the external temperature. The temperature blocking film may be formed of a heat resistant material such as styrofoam. The temperature blocking film may also be attached to the entire interior or exterior of the container body 120 continuously or partially.

In addition, when the temperature of the upper portion of the container body 120, which is mainly the larva 310 is active in the Dongae, such as 50 ℃ the lower part of the center of the container body 120 decomposed by the larvae Dongae, such as fermentation and air circulation of the mixture This raises the temperature to 60 ° C or higher. In order to prevent such a phenomenon, a temperature sensor may be installed at a lower portion of the disassembled center, and the temperature of the organic waste 320 may be lowered by using a cooling unit at a predetermined temperature, for example, 50 degrees or more. In addition, according to another embodiment, the operation may be adjusted by operating the cooling unit by looking at the temperature output to the temperature sensor.

Therefore, the organic waste treatment apparatus according to the embodiment of the present invention may further include a temperature controller for checking the temperature of the temperature sensor and operating the cooling unit when the temperature of the organic waste treatment is higher than or equal to a preset reference temperature.

The cooling unit may be a sprinkler using water or a cooling pen using air (wind). The cooling unit may lower the temperature inside the container body 120 until the temperature sensor indicates a predetermined temperature, for example, room temperature (eg, 25 ° C.).

The temperature below the center of the vessel body 120 is formed higher than the temperature of the upper and outer access points of the vessel body 120. Their temperature is higher than the ambient ambient temperature of the vessel body 120. The internal temperature of the container body 120 may be lowered by operating the cooling unit every six days when the temperature of the center lower portion of the container body 120 becomes 50 ° C. Increasing the amount of water in the sprinkler or attaching an air conditioner to the cooling pen can change the temperature rise and fall cycles or widths. In addition, ascending and descending cycles or widths may vary depending on the amount of water or the wind strength.

Therefore, by using the heater and the cooling unit, it is possible to adjust the temperature (for example, 35 ℃ to 45 ℃) inside the container body 120 so that larvae 310 inhabit the Dongae.

The organic waste treatment container has been described in general with reference to the drawings. Hereinafter, a breeding apparatus using the organic waste treatment container according to the present invention will be described with reference to specific embodiments with reference to the accompanying drawings. It will be described in turn below, it is obvious that the present invention is not limited to these embodiments.

4 and 5 are a perspective view and a side view of the apparatus using the organic waste treatment container described above. 4 or 5, the larva container layer 410, the structure body 420, the larva movement passage 430, the upper collector 440, the side collector 444 and 446, the body leg 450 ), A larvae outlet 453, a larvae discharge surface 456, and a collection bin 510 are shown.

The structure body 420 is formed of several layers, and each layer is provided with a larva container layer 410 which is a collection of the plurality of larval breeding containers described above. Referring to FIG. 4, the larva container layer 410 includes three breeding containers, but the present invention is not limited thereto.

When the larva container layer 410 is placed on each layer of the structure body 420, a larva movement passage 430 may be formed at the periphery of each layer to move the larvae discharged from each breeding container. The larva movement passage 430 may be formed as a separate groove or may be an area partitioned by the larva container layer 410 and the side wall of the structure body 420.

The body leg 450 supports the structure main body as a whole, and the through hole is formed so that the larvae can be collected by moving the larvae discharged from the larva container layer 410. The through hole is formed from the top to the bottom. The upper collector 440, which is the upper end of the through hole, and the side collectors 443 and 446 of the intermediate layer, are connected to the larval movement passages 430 of each layer. The upper collector 440 is formed at a portion where the uppermost layer of the structure body 420 and the body leg 450 are coupled to each other. Lateral collectors 443 and 446 are formed on the side of body leg 450 in the underlying layer.

A larvae outlet 453 is formed at the lower end of the main body leg 450. The larvae, which moved through the upper collector 440 and the side collector 444, 446 in the upper portion, falls on the larva discharge surface 456 of the lower and is discharged through the larva discharge port 453. The larvae discharge surface 456 may be inclined low toward the larvae outlet 453 so that the larvae may be discharged through the larvae outlet 453.

The case where the larvae outlet 453 is formed on the side surface of the main body leg 450 and the larvae discharging surface 456 is formed in the lower direction of the main body leg 450 is described, but the present invention is not limited thereto. For example, when the larvae outlet 453 is formed on the lower surface of the main body leg 450, and the separate larvae discharge surface 456 is not formed, the upper collector 440 and the side collector 444, 446 The larvae, etc. that moved through the dongae may fall directly down the body leg 450. In this case, a leg portion capable of supporting the structure body 420 may be separately provided or a portion of some of the plurality of body legs 450 may be formed to support the structure body 420.

The collecting container 510 is a box-like container that collects the larvae discharged through the larvae outlet 453 and the larvae discharge surface 456. The collector 510 is coupled to the lower portion of the body leg 450, it may be formed to be detachable. As shown, when the larvae discharging surface 456 discharges the larvae to the side of the main body leg 450, the collecting container 510 may be provided on the side of the main body leg 450.

According to another embodiment, as described above, when the larvae fall directly under the body leg part 450, the collecting container 510 may be located under the body leg part 450. Naturally, even in such an embodiment, the above-described heater, temperature sensor, cooling unit, and temperature blocking film may be applied.

Hereinafter, an experimental example of an organic waste treatment apparatus using larvae in Dongae, etc. according to an embodiment of the present invention will be described with reference to specific data.

Table 2 compares the concentrations of ammonia gas generated from the decomposition of food waste in the control and treatment groups.

Table 2. Ammonia Generation Concentration

The control group is a combination of food waste and sawdust, the treatment unit 1 is a combination of larvae for food waste, sawdust and dongae, and the processing unit 2 is a combination of larvae and microorganisms for food waste, sawdust, dongae and the like. Here, the introduced microorganism is yeast (yeast), the number of larvae in the injected Dongae, etc. 5000, used food waste is 10kg per day, sawdust serves to help control and fermentation. The size of the container used for the control and treatment is 1,200mm * 600mm * 200mm.

The ammonia concentration of the initial food waste was very high except for the control at 1.4 days in the control, 100.7 ppm in the treatment 1 and 113.9 ppm in the treatment 2. Also, on day 3, ammonia of 203.4 ppm in the control, 424.9 ppm in the treatment 1 and 386.7 ppm in the treatment 2 was generated.

This difference in concentration indicates that the foods in the treatment groups 1 and 2 are being degraded faster than the control, which is due to the larvae to Dongae. When decomposed by larvae in Dongae, etc., ammonia was relatively high in the early stages of treatment due to fermentation and food property degeneration.

In particular, since the larvae can not live in winter, such as larvae can be made to control temperature and humidity in four seasons, and in order to suppress the generation of ammonia, it is necessary to sterilize and chemical reactions of electrical and electronic or to exchange air inside and outside. Generalized systems such as heat exchange and air conditioning systems can be added to reduce and mitigate ammonia generation.

In addition, fecal soil discharged by the embodiment of the present invention is excellent in inefficiency bar can be useful for cultivation of farmland, horticulture, orchards, bar analysis of the components of the conversion product obtained from food waste as shown in Table 3 .
