[0031] In the present invention, first, a sealing test is performed. After the processing tank is sealed, the sealing door 2 is opened first, and then the animal tissue is placed in the processing tank, and then the sealing door 2 is closed; Then, compressed air is introduced into the processing tank to increase the pressure, and the pressure is maintained after it reaches 34KPa. After the pressure maintenance is qualified, 1% water is added to the processing tank. Then, the steam heating plate 10 cooperates with the heat transfer oil to heat the processing tank, so that the temperature inside the tank reaches 150 degrees, and the internal pressure reaches 300KPa, and then the pressure is maintained and the heat is maintained. The heat transfer oil in the inner shell 4 allows the material to be evenly heated in the subsequent heating process; After that, the interior is disinfected and dissolved, and the disinfectant solution is perfused into the interior through the spraying device 9. When the pressure and temperature inside the treatment tank remain unchanged, the first motor 6 is started, and its output end drives the stirring blade 7 and the stirring shell 8 to start, so as to stir the animal tissue inside for 4 hours. At this time, the animal tissue will be separated by the disinfectant solution, and the solid and part of the tissue will be separated. High-temperature disinfection can separate the fixed body in the animal tissue. Under high-temperature environment, the thermal motion of molecules is intensified. For the protein in the cell, its spatial structure is maintained by weak interactions such as hydrogen bonds and hydrophobic bonds. As the temperature rises, these weak interactions are destroyed, and the secondary and tertiary structures of the protein are changed, resulting in a change in the shape of the protein molecules, from the original orderly folded state to a loose state, thereby destroying the mutual binding between the proteins. At the same time, the high temperature will also evaporate the water in the cell, and the generated steam pressure will further promote the cell rupture, and various components in the cell such as organelles, nucleic acids, etc. and the connecting components between cells such as cell junction proteins will be separated accordingly; Then, the temperature setting value in the treatment tank is changed to 120°C, the distillation exhaust valve 5 and the first pressure reducing valve 3 are started, the pressure in the tank is reduced to normal pressure, and the drying time is 1 hour; After the stirring is completed, the solid animal tissue is on the filter layer 1102, and the decomposed liquid is on the inner shell 4, and then the first electric plate 1101 and the second electric plate 12 are changed from the closed state to the open state; Afterwards, the liquid and solid of the animal tissue enter the separator 14 through the first guide pipe 13 due to the negative pressure in the separator 14. The separator 14 performs gas-solid separation on the sucked-out material. Since the inside of the separator 14 is under negative pressure at this time, the gas is decompressed by the second pressure reducing valve 15 of the second guide pipe 16 at the upper end and enters the distillation device to be liquefied and discharged. The solid material is deposited at the bottom of the separator 14 and is discharged from the bottom of the separator 14 to the second guide pipe 16 at the lower end after the process is completed, and then enters the second shell 1701. Then, the alkali injection bonding process is started. A 35% concentration NaOH alkali solution with a volume percentage of 6% is added to the liquid injection interlayer 2102 through the water inlet 1702, and then flows into the inner shell 23 through the liquid outlet 39 on the inner shell 23. The heating device is started to heat the second outer shell 1701, and the temperature in the second outer shell 1701 is 125° C. in combination with the heat transfer oil in the heating layer 1703; After that, the second motor 22 and the third motor 28 on both sides of the second housing 1701 are started together. At this time, the second motor 22 works, and its output end drives the inner housing 23 to rotate, driving the first ring plate 25 in the period to rotate. When the first ring plate 25 rotates, it will drive the double-screw 27 in the first ring plate 25 to rotate, thereby increasing the air flow inside the first ring plate 25. The material inside the first ring plate 25 is a ceramic microporous membrane, and the ceramic microporous membrane is a membrane made of an inorganic material. It is formed by a special ceramic preparation process with a structure of regular or irregular micropores. The ceramic material itself has chemical stability and can withstand alkaline environments. The size of its micropores is generally in the nanometer to micrometer level. By controlling the size of the micropores, selective permeation of liquids and gases can be achieved. Due to its polarity and large size, water molecules are difficult to enter the micropores under the combined effect of the surface tension and micropore structure of the ceramic microporous membrane; while gas molecules can diffuse freely in the micropores, thereby preventing alkaline water from entering but allowing gas to blow out, so that the internal gas can be dispersed, while the alkaline water liquid will not enter, which facilitates part of the airflow to be pushed into and out of the first ring plate 25, improves the airflow disturbance effect on the material in the inner shell 23, and enhances the boring stirring and mixing effect; When the third motor 28 is started, its output end drives the connecting rod 29 to rotate, thereby driving the first rotating member 30 to rotate, and then drives the second ring plate 31 to rotate through the cross rod. The second ring plate 31 is provided with an inner bevel sheet 32 ​​inside. When the first ring plate 25 and the second ring plate 31 rotate, the outer bevel sheet 26 and the inner bevel sheet 32 ​​inside thereof push the materials near them during rotation, thereby forming a stirring and mixing effect; When the third motor 28 is working, it drives the connecting shaft 33 to rotate, and the connecting shaft 33 drives the second rotating member 35 to rotate through the telescopic rod 34, thereby driving the extrusion block 36 to rotate, and the inner blades 38 in the hollow groove 37 in the extrusion block 36 rotate accordingly, and the inclination direction of the inner blades 38 is the same as the rotation direction of the third motor 28, both are clockwise, and when the extrusion block 36 rotates, the telescopic rod 34 will also be extended and retracted, so that the extrusion block 36 squeezes the internal animal, and the inner blades 38 squeeze and filter the animal tissue to mix the animal tissue, so that it can be better combined; The third motor 28 rotates clockwise, and the cooperation of the first ring plate 25 and the second ring plate 31 will mix and stir the animal tissues, resulting in a mutual pushing effect. Because the second motor 22 and the third motor 28 have different rotation speeds and directions, this stirring in opposite directions can produce a stronger shear force, so that the animal tissues are subjected to forces from different directions in the alkali solution, thereby more effectively breaking up the tissue agglomeration, allowing the alkali solution to fully contact the tissues, and ensuring a more uniform adhesion process. At the same time, the outer bevel sheet 26 and the inner bevel sheet 32 ​​push the animal tissues back and forth inside, and cooperate with the rotating thread 24 to give the animal tissues more contact surfaces for air flow, and the telescopic rod 34 drives the extrusion block 36 The extrusion and stirring process can break up and disperse the animal tissue, greatly increasing the contact area between the tissue and external substances such as air, microorganisms, decomposition enzymes, etc. In the extrusion process, reasonable control of pressure and method can form a certain pore structure inside the animal tissue, and stirring helps to keep these pores unobstructed to prevent them from collapsing during subsequent processing. Good aeration is essential for aerobic microorganisms to decompose animal tissues, because these microorganisms need oxygen for respiration, thereby decomposing organic matter into nutrients that can be absorbed by plants, so that the internal animal tissue can be better bonded, and the pretreatment effect of becoming fertilizer can also be increased. The bonding time is 30 minutes; Afterwards, cooling and discharge are carried out. After bonding is completed, the heating device is turned off and the circulating water cooling mechanism is started. At this time, the water pump 19 works to pump water from the temperature-controlled water tank 20. Then the water pump 19 guides the water into the water pipe 18. The water pipe 18 passes the water into the annular water pipe 2101. The annular water pipe 2101 forms a wrapping method to cool the interior. First, in the initial stage, a relatively high temperature of 70°C is used for circulation. The temperature difference between this temperature and the temperature after animal tissue processing is small, so that the material has a buffer adaptation process. With the exchange of heat, the material temperature gradually decreases, and then the temperature of the cooling water is gradually reduced, each time by 5°C, until the temperature in the tank is reduced to 50°C. At the same time, in order to ensure the uniformity of cooling, the cooling water of the annular water pipe 2101 can evenly contact the tank body, so as to better reduce the temperature and form a gradient water cooling. Such a water cooling method can greatly reduce the effect of cold and hot shocks, and reduce the water consumption of the device, delaying the life of the equipment; Finally, the discharge bin door is opened, and the processed animal tissue is discharged through the discharge bin opening of the inner shell 23 corresponding to the discharge bin door.
