Description

High heat sterilization method for livestock animal carcasses and burial soil and high heat sterilization method for implementing the method{Method and Apparatus for High Temperature Sterilization for Deadstock and Burial Site Soil}

The present invention relates to an apparatus and a method for sterilizing the carcasses of animals or carcasses that have been killed or killed by an infectious disease such as AI or foot and mouth disease and the soil in which the carcasses are buried.

Avian influenza (AI), which occurs in some birds such as chickens, ducks, and turkeys, that is, avian flu, foot and mouth disease caused by animals with two hoofed animals such as cows, pigs, and sheep, has a high spread and high mortality. It has been a problem in livestock farms, etc., since it has been occurring every year in recent years, which has occurred in cycles of 2-3 years or more.

Moreover, these infectious diseases are subject to regulation during international trade, and when these infectious diseases occur, the export of the animal is completely stopped for a considerable period of time, and there is a problem that unaffected farmers also suffer greatly.

These infectious diseases can be prevented or prevented to some extent by antiseptics such as disinfectant spraying or vaccination, but once confirmed, the virus can be quickly killed by killing the animals in the farmhouse and farmhouses nearby. It is important to stop the spread.

Animals that have died or have been killed by the outbreak of an epidemic have typically been buried, causing problems such as soil contamination and groundwater contamination by leachate generation, and limiting the use of the land to affect property rights exercise. have.

Accordingly, methods of incineration or other methods of treatment, such as some developed countries, have been studied, rather than investing in dead or killed animal carcasses, which essentially involves or involves sterilization.

This sterilization treatment can be considered to be applicable to the animal carcasses that have been disposed of and then buried, and in this case, the carcasses of the buried animals will be excavated again to perform sterilization. However, even if the buried animal carcasses are dug up again, the buried soil is already contaminated with various pathogenic factors (bacteria, virus, prion, etc.) originating from the animal carcasses, and these pathogens can remain for quite a long time. , Even if the activity of the virus slows down due to the increase in temperature, pathogenic bacteria can proliferate more actively, so management of appropriate sterilization treatment is also required for buried soil.

The sterilization treatment of animal carcasses or buried soil is presented in Patent Publication No. 10-1067012 (Patent Document 1), Patent Publication No. 10-2015-0136624 (Patent Document 2), and the like.

The patent document 1 is a mobile animal investment disposal corpse treatment apparatus for pulverizing livestock carcasses excavated from a burial site, sterilizing in a sterilizer and carbonizing in a carbonizer, wherein the crushed carcass sludge is heated at low temperature by steam of 110 to 130 degrees Celsius. After sterilization with a high temperature sterilization treatment at a temperature of about 440 degrees Celsius to 550 degrees Celsius in the carbonizer to reduce the weight of carcass sludge to about 1/5, and also send the exhaust gas and dry gas from the carbonizer to the boiler to send it to the boiler. It is configured to undergo a process of oxidizing at a high temperature from 750 to 950 degrees to completely remove odors and contaminants.

However, the sterilization treatment apparatus of Patent Document 1 has a problem in that its configuration is quite complicated. In particular, when steam sterilization of an animal carcass is carried out by steam, saturated steam under atmospheric pressure does not exceed 100 degrees. In order to increase the temperature, it is necessary to make the temperature increase according to the saturated steam curve by increasing the internal pressure by generating steam or generating steam in an enclosed space. In any case, in the portable sterilization apparatus of Patent Document 1, As it is a difficult part to implement, it seems that it is inevitably adopting a high temperature sterilization process by a carbonizer. Moreover, in the high-temperature sterilization treatment process, since exhaust gas including soot is generated during carbonization, various problems arise, such as an additional need for an exhaust gas treatment process to remove it. Furthermore, the sterilization treatment apparatus of Patent Document 1 is not suitable for sterilization treatment of contaminated soil.

Published Patent Publication No. 10-2015-0136624 (Patent Document 2) describes a soil treatment method by chemical treatment as a sterilization method of buried soil, so it may take a considerable time to purify the soil by such chemical treatment. However, there is a problem that it takes time before the soil can be reused. Moreover, this chemical treatment method is applicable to sterilization and purification of soil, but it is difficult to apply to sterilization of animal carcasses.

Hereinafter, a method for high-temperature sterilization and a high-temperature sterilizer for livestock animal carcasses and burial land according to the present invention will be described in detail with reference to the accompanying drawings. First, a brief description of the configuration of the carcass processing apparatus of a livestock animal and a restoring apparatus of a buried soil of a livestock animal using a high heat sterilizer according to the present invention.

1 is a schematic diagram showing the carcass treatment apparatus of a livestock animal as a whole, and FIG. 2 is a schematic diagram showing a soil restoration apparatus of a livestock animal burial site according to the present invention.

The animal animal carcass handling device includes an input hopper 100, a livestock animal carcass transport conveyor 200, a crushing sorting device 300, a high-temperature sterilizer 400, a gravel sorting sorter 500, a deodorizer 600, and a discharge hopper. (700), the discharge portion transfer conveyor 800, and comprises a deodorant injection device (900).

In addition, the input hopper 100, livestock animal carcass transport conveyor 200, crushing sorting device 300, high-temperature sterilizer 400, gravel separator sorter 500, deodorizer 600, discharge hopper 700, Electric control panel (C), including discharge part transfer conveyor (800), deodorant sprayer (900), temperature and pressure measurement and control of required parts, log record of work history, power meter signal display and control device, etc. , Generator G for supplying power to all devices using electricity may be provided.

The input hopper 100 is a place where animal carcasses stored in a frozen or refrigerated container F for storage of animal carcasses or animal carcasses dug out of the burial site E are put into an animal carcass processing device to undergo a sterilization process. The animal carcasses input to the input hopper 100 may be transported by the livestock animal carcass transport conveyor 200 to be introduced into the inlet 310 of the crushing sorting device 300.

The livestock animal carcass transport conveyor 200 is formed by two or more spiral screw conveyors 210 arranged side by side inside the housing, and unlike conventional screw conveyors, animal carcasses are placed on the upper side of the screw conveyor 210. The crushing sorting device 300 is transferred to the upper side where the crushing sorting device 300 is located by the conveying action of the screw conveyor. However, a small piece of the animal carcasses may fall to the lower side through the gap of the screw conveyor 210, and the animal carcasses that have fallen to the lower side are pushed up by the spiral screw blade which rotates like a conventional screw conveyor device to the upper side. Can be transported.

The crushing sorting device 300 is a device that cuts and crushes an animal carcass to form sludge, that is, a sludge. The crushing sorting device 300 is a rotary cutter (not shown) capable of cutting animal carcasses to an appropriate size, and a sorting crusher (not shown) capable of sorting the cut carcasses by size and additionally crushing if necessary. It is made, and the animal carcass that has passed through the rotary cutting machine and the sorting crusher is discharged in a rough form and transferred to the next process by the crushing material transfer conveyor 360. The crushing sorting device 300 may be operated so that the animal carcass pieces are 5 cm or less, for example, but the size of the animal carcass pieces can be arbitrarily adjusted.

In addition, the liquid by-products generated in the process of cutting and crushing the animal carcasses are dropped into the preservative storage hopper 370 provided on the lower side of the sorting crusher 350, and the prejudice provided in the preservative storage hopper 370 After being absorbed by (腐mature腐), it is discharged together with the premature agent (sawdust, etc.) and transferred to the next process. The premature agent is discharged to the outside by the premature agent discharge conveyor 380, and is selectively supplied to the input part 430 and/or the sorting crusher of the high heat sterilizer 400 by the premature agent discharge device 390 provided on the outside. Can be sent.

The animal carcass in the form of a porridge discharged from the crushing screening device 300 is put into a high-temperature sterilizer 400 and sterilized. The adjuvant absorbing liquid by-products may also be introduced into the high-temperature sterilizer 400 for sterilization. This high-temperature sterilizer 400 is a high-temperature sterilizer for livestock animal carcasses and buried soil according to the present invention.

The high heat sterilizer 400 is provided with two heating devices. One is an induction heating device 423 that indirectly heats the outside of an animal carcass that mainly stays below the main body inside the high heat sterilizer by heating the bottom 411 of the high heat sterilizer body 410 formed of a metal that is a magnetic material. . The other is a microwave heating device 427 attached to the outside of the high heat sterilizer cover 413 formed of an electromagnetic wave transmissive material such as glass, which forms the upper part of the high heat sterilizer body 410 to directly heat the animal carcass. The induction heating device 423 and the microwave heating device 427 are provided together so that the dead carcasses are simultaneously heated inside and outside, so that heating can be achieved quickly. The temperature inside the high heat sterilizer 400 may be set to be arbitrarily adjustable, for example, between 100°C and 1000°C.

While heating the animal carcasses in the high-temperature sterilizer 400, water vapor and gas may be generated together with the stench. Since the high heat sterilizer 400 is kept sealed during heating, the internal pressure of the high heat sterilizer 400 gradually increases as the heating time elapses. When the pressure of water vapor or gas rises above a certain value, safety of equipment and workers is increased. It is preferably configured to discharge water vapor and gas. At this time, since the water vapor and gas discharged contain odors generated from animal carcasses, it is preferable to discharge them after performing the deodorization operation by the deodorizer 600.

Some of the water vapor that has reached the deodorizer 600 may be cooled and condensed during the deodorization process to turn into water droplets, and these water droplets will accumulate under the deodorizer 600. Since contaminants may remain, it is not desirable to discharge them as they are. Therefore, by providing a water discharge valve 610 under the deodorizer 600 and providing a pipe 613 from the water discharge valve 610 to the inlet 430 of the high-temperature sterilizer 400, accumulated Water is again put into the high-temperature sterilizer 400 to undergo a sterilization process again.

Animal carcasses that have been sterilized in the high heat sterilizer 400 are discharged to the discharge hopper 700 provided on the opposite side of the input 430 of the high heat sterilizer 400. The discharge hopper 700 is provided with a discharge part transfer conveyor 800 to discharge the sterilized animal carcasses. Sterilized animal carcasses can be transported on trucks and used for organic fertilizer production.

In addition, during the treatment of animal carcasses by spraying deodorant to the input hopper 100, the livestock animal carcass transport conveyor 200, the crushing sorting device 300, the crushing material transport conveyor 360, the discharge hopper 700, etc. A deodorant injection device 900 for reducing odor generated may be provided.

On the other hand, in the case of sterilizing the animal carcasses buried in the burial site, not only the animal carcasses but also the soil of the burial site must be sterilized to prevent the spread of livestock epidemics more reliably. Moreover, if the soil of the burial site is to be mixed with sterilized animal carcasses and used for the production of organic fertilizer or recycled for other purposes, such a sterilization process can be said to be essential.

The reduction or restoration of contaminated burial soils has been conventionally performed through chemical methods, and accordingly, it is often treated through a separate process from sterilization of animal carcasses. However, in the present invention, since the process of restoring the contaminated soil can be performed using a part of the animal carcass treatment process as it is, there is an advantage that the process is simplified and the necessary equipment is also reduced.

Restoration of the contaminated soil is accomplished by sterilizing the selected soil through the gravel separator 500 which separates and removes gravel and water from the buried soil, and then selecting the soil through the high-temperature sterilizer 400. . That is, it is possible to proceed with the sterilization process of the animal carcass sterilization process of the contaminated soil of the burial site just by adding one more gravel separator 500 to the animal carcass processing device.

Hereinafter, the configuration of the livestock animal carcasses and the buried soil high-temperature sterilizer 400 according to the present invention will be described in more detail in the configuration of the livestock animal carcass processing apparatus or the livestock animal burial site soil restoration apparatus.

3 and 4 are a front view and a side view, respectively, showing livestock animal carcasses and burial soil high heat sterilizer according to the present invention.

The high-temperature sterilizer 400 includes a main body 410, an input part 430, a Y-type inlet 440, a stirring blade 460, an induction heating device 423, a microwave heating device 427, and a water vapor outlet 470 , Including the discharge switch 480, the main body support 490, and the like.

The input part 430 is located on the upper side of one side in the longitudinal direction of the high-temperature sterilizer main body 410 and is provided to be opened and closed. Referring to FIG. 5, the Y-type inlet 440 provided adjacent to the inlet 430 is provided to be slidable along a guide rail 455 provided on an upper side of the high-temperature sterilizer main body 410, When the input unit 430 is opened, it is moved to be positioned above the input unit 430, and when the input unit 430 is closed, it is first moved to a position spaced apart from the input unit 430 and the input unit (430) Interference should not occur when closed.

5, an embodiment of a configuration involved in opening and closing of the input unit 430 will be described in more detail. In the illustrated embodiment, the input port moving means 450 is composed of a cylinder 453 slidingly moving the Y-type input port 440 along the guide rail 455 and the guide rail 455. When the high-temperature sterilizer cover 413, which will be described later, is opened, the cylinder 453 is drawn out and the Y-type inlet 440 is positioned above the inlet 430, and when the high-temperature sterilizer cover 413 is closed, the The cylinder 453 is drawn in and moves the Y-type inlet 440 to a position spaced apart from the inlet 430.

The high heat sterilizer cover 413 for opening or closing the input part 430 is driven by a cover driving means 415, and in the illustrated embodiment, the cover driving means 415 is a high heat sterilizer cover 413, a cylinder 417 ) And the hinge (419). As shown in Figure 5, the high heat sterilizer cover 413 is provided to be rotatable with a hinge 419 as a rotation axis, and the cylinder 417 is connected to one end of the high heat sterilizer cover 413, and the high heat sterilizer cover 413 By rotating the hinge 419 around the high-temperature sterilizer cover 413 is configured to open and close the input unit 430.

The cylinders 453 and 417 can be applied in various ways, such as a pneumatic cylinder, a hydraulic cylinder, or a linear motion device composed of a motor and a ball screw, but when applied as a hydraulic cylinder, the hydraulic pump 403 provided in the high-temperature sterilizer 400 It can be utilized, there is no need to provide a separate pneumatic compressor or the like, there is an advantage to increase the economic efficiency.

Meanwhile, the Y-type inlet 440 includes a first inlet 441 and a second inlet 443 on the upper side, and both the first inlet 441 and the second inlet 443 on the lower side. When it is in communication with the input unit 430 and is located above the input unit 430 is provided with a mobile inlet (447) to communicate with the input port (430). Thanks to the Y-type inlet 440 having such a configuration, it is possible to simultaneously or alternately perform animal carcass treatment and restoration of contaminated soil.

Moreover, a trident-type inlet provided up to a third inlet (not shown) is provided in place of the Y-type inlet 440 for a smooth input of a premature agent that can be additionally added to lower the water content of the animal carcasses. It might be.

Inside the high-temperature sterilizer 400, a screw conveyor-shaped stirring blade 460 is provided, and the stirring blade 460 is rotated around a rotation axis provided along the longitudinal direction of the high-temperature sterilizer main body 410 to insert the input part ( 430) is stirred through the animal carcasses. Since the stirring blade 460 requires relatively large power to operate, the rotation shaft is rotationally driven by a hydraulic pump 403 and a hydraulic motor 405 provided outside the high-temperature sterilizer body 410. One side of the rotating shaft is connected to the hydraulic motor 405, and the other side is rotatably supported by a support bearing provided outside the high-temperature sterilizer body 410.

The high-temperature sterilizer 400 is provided with two types of heating devices. That is, the induction heating device 423 is provided on the lower outer side of the high-temperature sterilizer main body 410 to indirectly heat the animal carcasses inside the main body by heating the main body bottom 411 formed of a magnetic material, and the high-heat sterilizer main body ( 410) is a microwave heating device 427 provided on the outside of the high heat sterilizer cover 413 formed of a material through which electromagnetic waves, such as glass, form an upper portion and directly heat the animal carcasses inside the body.

The microwave heating device 427 operates to heat the selected soil from the inside by vibrating and heating water molecules present inside the selected soil or animal carcass, and the induction heating device 423 of the high-temperature sterilizer body lower part 411 It is installed on the outer surface to indirectly heat the selected soil located inside the bottom of the high heat sterilizer body by conduction, convection, and radiation of heat from the bottom of the high heat sterilizer body by heating the bottom of the high heat sterilizer body. It is a feature of the high-temperature sterilizer according to the present invention that the heating of the selected soil and the like can be performed more quickly by simultaneously using the device and evenly stirring the selected soil by the stirring blade 460.

The upper side of the other side in the longitudinal direction of the high-temperature sterilizer main body 410 is provided with a water vapor discharge port 470 capable of discharging water vapor and gas generated from animal carcasses. The water vapor discharge port 470 may be provided to be automatically opened or closed by manual operation or upon reaching a set pressure. Since the high-temperature sterilizer main body 410, the input part 430, and the water vapor discharge port 470 are manufactured to withstand an internal pressure of at least 6 kgf/cm 2, it is automatically operated at a set pressure of 4 kgf/cm 2 or higher. A pressure switch 473 set to be opened is provided at one side of the water vapor discharge port 470 to discharge water vapor and gas generated inside the main body. However, the pressure switch 473 is provided for temporary pressure control rather than discharge of pressure, and thus, after sterilization process by the high heat sterilizer 400 is finished, before sterilized animal carcasses are discharged, the inside of the high heat sterilizer 400 is used. The pressure reducing valve 475 is additionally provided in order to release pressure, or to quickly reduce the pressure when the pressure applied to the pressure switch 473 is increased or the pressure is rapidly increased during the sterilization process. It is preferably provided.

The lower side of the other side in the longitudinal direction of the high-temperature sterilizer main body 410 is provided with an open-and-closed discharge switch 480 to discharge animal carcasses, etc. which have been sterilized. When discharging animal carcasses or the like through the discharge switch 480, it will be necessary to transfer the animal carcass or the like inside the high-temperature sterilizer main body 410 to the discharge switch 480 by operating the stirring blade 460.

The high-temperature sterilizer main body 410, the hydraulic pump 403, the hydraulic motor 405, etc. are all disposed and supported on the main body support 490. The body support unit 490 is provided with a weight detector 495 to measure the total weight of the animal carcasses injected into the body 410, whereby the animal carcasses of an appropriate weight can be processed every sterilization cycle.

In addition, the weight detector 495 may be provided in two or more spaced apart from each other in the main body support 490, in this case it is possible to measure the weight distribution of animal carcasses, etc. in the body 410. If weight distribution is appropriate, there is no need to take special measures, but for example, during the injection of animal carcasses, etc., animal carcasses, etc., only accumulate on the lower part of the input part 430, and it may be difficult to add additionally, even though it has not been injected with the proper weight. In this case, in this case, the weight distribution will be measured to be too much weighted to one side. At this time, it will be desirable to continue the further input after moving the animal carcass or the like by operating the stirring blade 460.

Hereinafter, with reference to FIGS. 6 to 8, look at in more detail with respect to the stirring blade of the configuration of the high-temperature sterilizer according to the present invention.

6 is a schematic view showing a stirring blade inside the body of the high-temperature sterilizer in FIG. 3, FIG. 7 is a perspective view for explaining a stirring wing and a stopper which are components of the present invention, and FIG. 8 is a stirring wing which is a component of the present invention. It is a plan view for explanation. 6 and 7, the induction heating device 423 is omitted for convenience of illustration of the internal structure of the high heat sterilizer main body 410.

The stirring blade 460 of FIG. 5 is provided with a transfer blade 460a that is formed by drawing a spiral on the outside of the rotating shaft that is rotated by receiving power and moves the object to be treated. The stirring blade 460b is formed while drawing a spiral from the outside of the conveying blade 460a, but is formed while drawing a direction opposite to the spiral direction of the conveying blade 460a. On the other hand, a space 460c is formed between the conveying wing 460a and the stirring wing 460b, and the stirring wing 460b has a broken portion 460ba.

This structure is such that when the stirring blade 460 is rotated, the selected soil, the crushed animal carcass, the premature agent, and the like can be smoothly moved and stirred. Therefore, the phenomenon in which the selected soil, the crushed animal carcass, and the premature admixture are not mixed and can only be moved can be prevented.

In the present invention, the wall surface inside the high-temperature sterilizer main body 410 is provided with a stopper 417 extending to form a protruding jaw, so that the object to be stirred is hung on the stopper 417 and mixed to sort soil, crushed corn Stirring of animal carcasses, premature agents, etc. in a state can be made more smoothly. The stopper 417 as described above may be implemented in the form of a square pipe or a square, as in the accompanying drawings.

With reference to Figure 9 looks at the method of high-temperature sterilization by the animal body carcass and buried soil high-temperature sterilizer according to the present invention.

Sterilization of livestock animal carcasses and/or buried soil by the high heat sterilizer 400 first closes the discharge switch 480 of the high heat sterilizer 400 and then the livestock animals that are subsequently introduced into the high heat sterilizer body 410 It is initiated by preventing the carcasses and/or buried soil from spilling during the sterilization process (S210). Subsequently, the input unit 430 of the high-temperature sterilizer 400 is opened, and the Y-type input port 440 is moved to be positioned above the input unit (S220).

Optionally, when the contaminated burial soil is to be sterilized alone or with an animal carcass, the gravel and water are separated from the contaminated burial soil through the gravel separator 500 provided separately from the high-temperature sterilizer 400. After removing the remaining soil, that is, selecting soil, it may be prepared to be input to the high-temperature sterilizer 400.

Subsequently, through the Y-type inlet 440 and the inlet 430, the selected high-temperature sterilizer main body 410 is divided into selected soils selected from contaminated soil and/or crushed animal carcasses, respectively. (S230). At this time, the selected soil refers to the discharged soil after removing the gravel and water by putting the contaminated burial land into the gravel separator 500. The Y-type inlet 440 may be provided with three divided inputs, so that in addition to the selected soil and animal carcasses, a pre-adjustment agent capable of controlling the content of moisture contained in these selected soils or animal carcasses can be additionally inputted. . The selected sorted soils are mixed together while passing through the Y-type inlet 440 and entering the input unit 430.

When the weight of the selected soil and/or the animal carcass injected into the hyperthermic sterilizer main body 410 has reached a preset value, the Y-type inlet 440 is introduced when the weight detector 495 detects it. Move to the position spaced apart from the unit 430 and close the input unit 430 (S240).

Now, by rotating the stirring blade 460, the selected soil and/or the animal carcasses injected into the main body 410 are stirred while the induction heating device 423 and the microwave heating device 427 are operated. Sterilization is performed by heating the selected soil and/or the animal carcasses injected into the main body 410 for a predetermined time or more at a preset temperature (S250).

In order to heat the selected soil or animal carcasses in a heating step for sterilization (S250), a microwave heating device 427 heating the selected soil or the like from inside by vibrating and heating water molecules present in the selected soil or animal carcasses. And, an induction heating device installed on the outer surface of the lower portion of the high-temperature sterilizer main body to indirectly heat the selected soil located inside the bottom of the high-temperature sterilizer body by conduction, convection, radiation, etc. by heating the bottom of the high-temperature sterilizer body. The use of (423) at the same time is a feature of the high-temperature sterilization method according to the present invention.

The sterilization conditions may be, for example, 15-20 minutes at 121°C or 35 minutes at 115°C for wet heat treatment, or 1-2 hours or more at 160-170°C for dry heat treatment.

When the sterilization process is completed after the predetermined time has elapsed, the induction heating device 423, the microwave heating device 427, and the stirring blade 460 are stopped, and the decompression valve 475 is opened to open the heated steam. When the inside temperature of the main body 410 falls below a predetermined safety temperature, the discharge switch 480 is opened to discharge the sterilized selected soil and/or animal carcasses (S260). The agitation vane 460, which acts like a screw conveyor, can be operated again for the discharge of sterilized sorted soil and/or animal carcasses.

When the animal carcass discharging is completed, sterilization of the selected soil and/or animal carcasses is completed by stopping the stirring vane 460 and closing the discharging switch 480 (S270).

With reference to the accompanying drawings, the livestock animal carcasses and buried soil hyperthermic sterilizer according to the present invention have been described, but these are illustrative and should not be construed as limiting the scope of the present invention, and the scope of the present invention is as follows.
