Description

A harmless treatment process and device for dead animals Technical Field

[0001] The present invention relates to a process and device for harmless treatment of dead animals, and in particular to a process and device for harmless treatment of dead animals, belonging to the technical field of harmless treatment of dead animals. Background Art

[0002] In recent years, when major animal diseases occur, they have caused great harm to the health of livestock farmers. Animal health and safety issues not only affect the growth, health and economic benefits of animals, but also threaten human health and social stability. Animal health and safety issues have become a focus of common concern for the whole society. There are many factors that lead to this situation, and one of the important reasons is that dead animals cannot be disposed of in a timely and effective manner. Dead animals are not disposed of in accordance with relevant national regulations.

[0003] Harmful disposal of dead animals can easily lead to the spread of major animal diseases and zoonotic diseases, especially if dead animals enter the consumer market, which directly threatens public health. Strengthening the harmless disposal of dead animals is related to the healthy development of animal husbandry and the health and safety of the people. In some areas, farms indiscriminately discard dead animals, seriously affecting public health and safety.

[0004] Currently, there are several methods for harmless treatment of dead animals, including incineration, chemical treatment, burial, and fermentation. The incineration method is thorough but consumes a lot of energy and has low economic benefits; the burial method occupies a large amount of land resources and is prone to contaminating groundwater; the fermentation method takes a long time and cannot be used for the treatment of a large number of dead animals. The current chemical treatment method uses high temperature and high pressure, which has a large processing capacity and the treated product is more conducive to use as organic fertilizer, but there are still some shortcomings: 1. Dead animals are directly fed without being crushed, which has high equipment requirements and a long processing time; 2. Secondary pollution is easily caused during the treatment process; 3. Normal pressure drying is used, which consumes a lot of energy, generates a lot of waste gas and wastewater, and has a high processing cost. The harmless treatment device and process method for dead animals need to be further improved and optimized. Therefore, it is very necessary to invent a harmless treatment process and device for dead animals.

[0005] Summary of the Invention

[0006] The technical problem to be solved by the present invention is that the current chemical method adopts a high-temperature and high-pressure method, which has a large processing capacity and the processed product is more conducive to being used as organic fertilizer, but still has shortcomings: 1. Dead animals are directly fed into the feed without being crushed, which places relatively high requirements on equipment and a long processing time; 2. Secondary pollution is easily caused during the processing; 3. Normal pressure drying is used, which consumes a lot of energy, generates a lot of waste gas and wastewater, and has a high processing cost.
