Description

A resource circulation system that uses the weight loss generated from the food waste reduction machine for insect breeding}

The present invention relates to a resource circulation system, and in particular, allows insects such as black soldier flies to eat the waste generated from a food waste reducer (i.e., food waste dried to contain moisture below a certain level) without disposing of it. It is about a resource circulation system that uses the waste generated from food waste reduction equipment for insect breeding.

The increase in waste emissions due to rapid industrial development and population growth has been pointed out as a cause of serious environmental pollution.

Among these wastes, especially food waste discharged from homes, restaurants, and food manufacturing plants, not only creates a strong odor and becomes a pollution in itself, but also pollutes water quality by promoting eutrophication of water when it flows into rivers. It causes serious problems such as

Therefore, in order to solve the problem caused by food waste, various technologies for food waste reduction devices that reduce and discharge food waste have been developed, and recently, devices for fermentation and composting by microorganisms have also been proposed.

However, no matter what method of food waste reduction equipment has been presented so far, it takes a lot of time, manpower, and money, and composting the reduced waste is not easy due to salt content, and even if composted, farmers avoid using it, which leads to resource circulation. There was a problem with it not operating smoothly.

Meanwhile, national investments have recently been made to foster insect resources as a next-generation new growth industry. In particular, research and investment are being focused on utilizing insects in fields such as alternative proteins, health functional foods, and pharmaceutical materials.

Figures 1 to 4 show a resource circulation system that uses the waste generated from the food waste reduction device according to the present invention for breeding insects, and Figures 5 and 6 show insects in the resource circulation system shown in Figures 1 to 4. This is a province that shows a breeding machine and an automatic weight loss feeder,

Figures 7 to 9 are diagrams showing the insect rearing machine of the resource circulation system shown in Figures 1 to 4 and the insect breeding machine of the automatic loss weight transfer machine.

The resource circulation system that uses the waste generated from the food waste reducer according to the present invention for breeding insects includes a food waste reducer (100) that converts food waste into reduced water with a certain moisture content and discharges it, and an insect rearing machine ( 200) and an automatic weight loss feeder 300 that automatically supplies the weight loss discharged from the food waste reduction device 100 as food for insects accommodated in the insect breeding device 200.

The food waste reducer 100 receives food waste, makes it have a moisture content at a set level, and discharges it to the outside.

This food waste reducer 100 includes a housing 110, a stirring tank 120, a heat exchanger 130, a blower 140, etc. provided inside the housing 110.

The housing 110 has the appearance of a food waste reducer 100, and is equipped with an inlet 111 on the top through which food waste is supplied, and an outlet 112 on the side for discharging waste with a certain moisture content. and a control panel 113 is provided.

The inlet 111 is a hole through which food waste containing a large amount of moisture falls into the stirring tank 120, and is opened and closed by a cover 111b that automatically rotates by the rotational force of the drive motor 111a. That is, when the motor shaft of the drive motor 111a rotates in one direction, the cover 111b rotates to open the inlet 111, and when the motor shaft of the drive motor 111a rotates in the other direction, it seals the inlet 111. .

The discharge port 112 is a hole through which food waste treated to have a set moisture content through a stirring process and a heat exchange process, i.e., discharged waste, is discharged to the outside. This discharge port 112 is also opened and closed by a cover 112a that is automatically opened and closed through manipulation of the control panel 113.

The control panel 113 is equipped with various buttons to control the operation of the food waste reduction device 100, the insect breeding device 200, and the reduced waste automatic transfer device 300. In particular, the insect breeding device 200 When the button for sending water is pressed, the agitation tank 120 sends the reduced water with the moisture content in the food waste to about 20 to 25% to the insect rearing machine 200.

The stirring tank 120 stirs the food waste supplied through the inlet 111 to have a certain moisture content.

The heat exchanger 130 discharges high-temperature air containing bad odors generated in the stirring tank 120 to the outside, lowers the temperature, and then re-introduces it into the stirring tank 120.

The blower 140 sucks the heat generated during heat exchange by the heat exchanger 130 and provides it to the insect rearing machine 200. That is, the high-temperature air generated in the stirring tank 120 discharges heat to the outside as it passes through the heat exchanger 130, and the temperature decreases. At this time, the discharged heat is provided to the insect rearing device 200, so that the generated heat is not discarded and the insects are infected. Supplies a certain amount of heat source required for breeding.

The insect breeder 200 is a device for receiving the waste material provided from the food waste reducer 100 and breeding insects contained therein, including a cabinet 210 and a plurality of supports 220 installed inside the cabinet 210. ), a plurality of baskets 230 installed on both left and right sides of the support 220, a plurality of rotation motors 240 installed on the support 220, and rotatably installed on the support 220. It includes a weight loss guide plate 250 and a heater 260 installed on the bottom of the cabinet 210.

The cabinet 210 has the outer shape of the insect rearing machine 200, and has a weight loss input hole 211 formed on the upper surface into which weight loss water provided through the automatic weight loss feeder 300 is input.

The front of the cabinet 210 is provided with a rotatable door 212 for easily inserting or removing insects from the basket 230.

A pair of the supports 220 is installed inside the cabinet 210 at a certain distance apart in the front and rear directions. A plurality of such pairs of supports 220 may be installed in the left and right directions.

And, a temperature sensor 221 is installed on the support 220.

The temperature sensor 221 measures the temperature inside the cabinet 210 to which waste heat from the blower 140 is supplied and determines whether the temperature inside the cabinet 210 is appropriate for raising insects. The temperature measured by the temperature sensor 221 is transmitted to the control panel 113 provided in the housing 110, and the control panel 113, which receives the temperature value, determines whether the temperature is appropriate for raising insects and detects whether the temperature is low. The heater 260 is operated, and when the temperature is high, the heater 260 is stopped.

The basket 230 is installed on both left and right sides of the support 220 to be spaced apart in the vertical direction. This basket 230 accommodates insects to be reared therein.

In the present invention, black soldier flies can be selected as the insects reared inside the basket 230.

As is known, the black soldier fly is an insect that pupates after growing for about 15 days, and has been designated as a future food insect. It is being piloted in many researches and waste disposal in foreign countries, and even in poor environments, it grows by eating food waste and extracts protein and fat. Additional commercialization is possible. In addition, black soldier flies have various advantages such as antiviral resistance, so they are suitable as insects to be reared in the basket 230.

Meanwhile, the basket 230 is formed to be bent downward so that the upper end faces inward. That is, by bending the upper part of the side wall of the vertical basket 230 inward by more than 90 degrees, insects accommodated inside are prevented from climbing up the side wall of the basket 230 and escaping out of the basket 230.

The rotation motor 240 is installed on the support 220 to be spaced apart in the vertical direction. In more detail, the rotation motor 240 is installed on one of the pair of supports 220 installed in the front-back direction and spaced apart in the vertical direction.

The weight loss guide plate 250 is installed on the support 220 to be spaced apart in the vertical direction, and receives rotational force from the rotation motor 240 to rotate and tilt in the left and right directions, thereby falling through the weight loss input hole 211. The reduced water is supplied to the baskets 230 on both left and right sides.

In more detail, one end of the weight loss guide plate 250 is connected to the motor shaft of the rotation motor 240, and the other end is rotatably installed on the support 220. In this state, when power is supplied to the rotation motor 240, the motor shaft of the rotation motor 240 rotates, and the weight loss guide plate 250 connected to this motor shaft also rotates.

Therefore, when supplying the reduced water produced in the food waste reducer 100 into the insect rearing machine 200 through the reduced water input hole 211, power is supplied to the rotation motor 240 to control the reduced water induction plate located at the top. When (250) is tilted in either the left or right direction, the weight loss slides downward along the uppermost weight loss guide plate 250 and is supplied into the basket 230 at the top.

And, when trying to supply loss weight to the basket below, that is, the second basket, the weight loss guide plate at the top is rotated to make it vertical, and at the same time, it is supplied to the rotation motor immediately below, that is, the second rotation motor from the top. Supply power to cause the second weight loss guide plate from the top to tilt in either the left or right direction. In this state, when the weight loss is supplied through the weight loss input hole 211, the weight loss flows downward through the second weight loss guide plate 250 from above and is supplied to the second basket.

While repeating this process, the weight loss is supplied to the basket 230 located at the bottom.

Meanwhile, it is desirable to ensure that no gap is created between the weight loss guiding plate 250 and the basket 230 through which the weight loss is to be supplied. This is because if a gap occurs between the weight loss guide plate 250 and the basket 230, the weight loss may go down along the weight loss guide plate 250 and leak through the gap. In order to minimize the occurrence of such empty gaps, a leak-proof silicon plate 231 is provided on the upper outer surface of the basket 230.

In other words, the leak-proof silicon plate 231 does not interfere with the rotation of the weight loss guide plate 250 and prevents a gap from occurring between the basket 230 and the weight loss guide plate 250.

The heater 260 is installed inside the bottom surface of the cabinet 210 to increase the temperature inside the cabinet 210. A diffusion fan 261 is installed on one side of the heater 260 to evenly diffuse the heat emitted from the heater 260 inside the cabinet 210.

Meanwhile, a filter 213 is installed in the cabinet 210, and the heat provided by the blower 140 flows into the cabinet 210 after dust or foreign substances are filtered by the filter 213.

The automatic food waste feeder 300 automatically supplies the food waste discharged from the food waste reducer 100 as food for insects accommodated in the insect rearing machine 200.

This automatic weight loss container 300 includes a weight loss container 310, a transfer pipe 320 connected to the weight loss container 310, and a helical transfer screw 330 provided inside the transfer pipe 320. ), a weight loss transport motor 340 that provides rotational force to the helical transport screw 330, and a weight loss supply pipe 350 provided in communication with the transport pipe 320.

The weight loss container 310 stores the weight loss discharged through the discharge port 112 until it is transferred by the automatic weight loss weight transfer machine 300.

One end of the transfer pipe 320 is inserted into the weight loss container 310, and the other end is located on the upper surface of the insect rearing machine 200.

One end of the helical transfer screw 330 is inserted into the reduced product stored inside the reduced product container 310. When the helical transfer screw 330 rotates, the weight loss is transferred upward along the helical transfer screw 330.

The weight loss transfer motor 340 rotates the helical transfer screw 330 to transfer the weight loss inside the weight loss container 310 to the other end of the transfer pipe 320.

One or more weight loss supply pipes 350 are provided in the transfer pipe 320. To elaborate, the weight loss supply pipe 350 is provided with the same number of weight loss input holes 211 formed on the upper surface of the insect rearing machine 200. This weight loss supply pipe 350 discharges the weight loss transported inside the transfer pipe 320 toward the weight loss input hole 211 and supplies it to the inside of the insect rearing machine 200.

Meanwhile, an opening and closing plate 352 is provided at the bottom of the weight loss supply pipe 350 to open and close the pipe by the rotational force of the opening and closing motor 351.
