Description

Technical Field

[0001] The present invention relates to the technical field of epidemic prevention and control, and in particular to an animal carcass processing device and method for epidemic prevention and control. Background Art

[0002] Animal carcasses may carry various dangerous pathogens, including bacteria (such as anthrax and Brucella), viruses (such as foot-and-mouth disease virus and avian influenza virus), parasites and their eggs, and prions (although their effectiveness against prions is controversial); the synergistic effect of high temperature, high pressure and steam (moisture) can destroy protein structure (denaturation), cell membranes / walls, and nucleic acids (DNA / RNA), thereby rendering most pathogens inactive and unable to replicate, thereby achieving the purpose of epidemic prevention.

[0003] The core of high-temperature and high-pressure steam treatment (often called steam sterilization or wet sterilization) to achieve harmless treatment and epidemic prevention of animal carcasses lies in the synergistic effect of high temperature, moist heat and pressure to completely inactivate pathogenic microorganisms.

[0004] According to the invention application number of Chinese patent application No. 202110944209.3, there is an animal carcass decomposition method and an animal carcass decomposition machine. When in use, the animal carcass decomposition method and the animal carcass decomposition machine first pre-crush the animal carcass, crush the animal carcass into small pieces, and then stir and decompose it to improve the decomposition efficiency while avoiding the occurrence of overload. The pre-crushed animal carcasses are relatively small, so that more animal carcasses can be accommodated in the equipment without the need for additional decomposition, reducing the operation process and operation time, reducing operation costs, and improving competitiveness; at the same time, assisted by heating and exhaust, the degradation efficiency can be greatly improved. However, the animal carcass decomposition method and the animal carcass decomposition machine only use heating and exhaust to degrade animal carcasses when in use. Although the comparative document uses pre-crushing to improve efficiency, its open processing still leads to the risk of pathogen spread. The present invention fundamentally solves this defect through closed high-pressure sterilization. Therefore, it is necessary to propose an animal carcass processing device and method for disease prevention and control to solve the above-mentioned problems. Summary of the Invention

[0041] Step 1: feeding the animal carcass into the high-temperature and high-pressure reactor 2 through the first feeding channel 4, and activating the sealing component 6 to close the channel;

[0042] Step 2: Steam is introduced into the high-temperature and high-pressure reactor 2 through the treatment and conveying assembly 8 to maintain an environment with a pressure of ≥0.3 MPa and a temperature of ≥120°C for more than 30 minutes, and dry air is introduced through the treatment and conveying assembly 8 to dry and weather the animal carcass;

[0043] Step 3: Open the sealing assembly 6 again to transport the dried diseased animal carcasses into the crushing box 3;

[0045] Step 5: After the crushing is completed, the crushed material is collected and processed through the material conveying pipe 14, and the processed crushed material can be reused as raw material.

[0046] In the case implementation, the fixed frame 1 serves as the main supporting structure, with the high-temperature and high-pressure reactor 2 and the crushing box 3 integrated inside; the first feed channel 4 is connected to the reactor 2 on the left side of the top, and the second feed channel 5 is connected to the crushing box 3 on the right side, forming a dual-channel independent feed; from the side, the fixed pipe 801 of the processing and conveying component 8 can be seen passing through the side wall of the reactor 2; the top of the feed channel is equipped with a sealing component 6, which is dynamically closed by the high-pressure sealing plate 603.
