Sanitation crusher of the animal carcasses

The present invention relates to a sanitary pulverizing apparatus capable of sanitizing the livestock killed by infectious diseases such as foot-and-mouth disease and bird flu without contaminating the environment.

Recently, livestock epidemics and various diseases such as foot-and-mouth disease and bird flu have spread widely. In particular, foot and mouth disease (FMD) is a fatal disease of cattle and is classified as Class A in the Office International des Epizooties. This foot-and-mouth disease can infect all species of cloven-hoofed animals, such as cattle, pigs, sheep and goats.

Livestock infected with such infectious diseases or various diseases prevents the spread of pathogens through killing. Animals that are slaughtered here are disposed of by burial or incineration, but they prefer to be buried because of cost.

However, in the method of burying the slaughtered livestock, leachate and odor are generated while the livestock is decayed at the burying ground. If such leachate flows into the groundwater or odor occurs, it causes environmental pollution. In particular, in recent years, foot-and-mouth disease has been prevalent all over the country, and as a result, environmental pollution is a serious problem as the animals are buried in large numbers of livestock killed in the vicinity of the foot-and-mouth area.

On the other hand, in order to sanitize, rather than bury or incinerate slaughtered livestock, the slaughtered livestock must be crushed and sterilized. In the pulverizing apparatus for crushing livestock thus disposed, infectious material is buried on the parts when the livestock is crushed. Therefore, after the treatment of the slaughtered livestock is completed, there is a need for a process of disinfecting the inside of the grinder separately.

That is, the NaDCC disinfectant used in the sanitary pulverizing device of the present invention as shown in [Table 1] is not only excellent in stability and convenience compared to conventional Lax based disinfectants, but also has a sterilizing power of about 80 to 100 times higher than that of Lax based disinfectants. It is easy to sterilize the decaying bacteria caused by livestock decay.

Next, after disinfecting the organic matter of the pulverized livestock with a NaDCC disinfectant to make a liquid fertilizer using a dispersion facility. Looking at the process of making a liquid fertilizer as described above, as shown in Figure 2, by moving the organic material of the livestock disinfected with NaDCC disinfectant to the microbial agent storage tank 110, the microorganisms are stored to remove the odor of the organic matter of the livestock, the odor is removed The organic matter of the domesticated animal is granulated by destroying cells of the organic material of the domestic animal using the disperser 120, and the organic material of the micronized animal is repeatedly transferred to another microbial agent storage tank 130 in which the microbial agent is stored to ferment and decompose and fermented. The organic material of the decomposed livestock is precipitated in the solid-liquid separation tank 140, and the precipitated fermentation liquid, that is, liquid fertilizer is separated and stored in the liquid fertilizer storage tank 150.

Specifically, microbial agents are photosynthetic bacteria (PCB) that absorb nutrients by decomposing hydrogen emulsification or nitrogen compounds that are decomposed as organic matters, and decaying bacteria that are the source of odor by inhibiting and killing the growth of decaying bacteria. Contains fermentation bacteria to rescue.

The organic matter of the livestock whose odor has been removed by the microbial agent is micronized by the disperser 120. In this case, the disperser 120 includes a tank 121 into which a liquid containing organic matter of livestock is introduced, a rotating unit 123 for rotating the inside of the tank 121 at high speed, and a rotating unit 123. The microbubble generator 125 further subdivides the suspended solids caused by the organic matter of the livestock by the action of the ultrasonic waves generated when the microbubble bursts by introducing the microbubble at a high pressure into the tank 121 rotated at high speed. It includes.

At this time, the normal cell is a strong and flexible structure surrounded by the membrane of the cytoplasm, cell wall, mucus or capillaries and several layers of membranes, the disperser 120 rotates the liquid containing the organic matter of the animal at high speed to the organic matter of the livestock The impact phenomenon and the cleavage phenomenon that occurs when the collision collides violently causes the cell membrane and the intracellular substance to be pulverized into fine particles.

The microbial agent used to ferment and decompose the organic matter of the micronized livestock is the same component used to remove odors, i.e., the same microbial agent including photosynthetic bacteria and fermented bacteria. At this time, the microbial agent adheres to the cells of the organic material of the granulated livestock in the state of being stored in another microbial agent storage tank 130 as described above to ferment and decompose.

The organic matter of the fermented and decomposed livestock is naturally precipitated in the solid-liquid separation tank 140 as described above, the precipitated fermentation broth becomes a liquid fertilizer and part of the precipitated cell debris is returned to the disperser 120 again. Atomization treatment takes place. And the supernatant generated in the process of precipitation of the organic matter of the livestock as described above has the same properties as the microbial stock solution is mixed with the microbial stock solution and reused.
