Problems solved by technology

[0003] However, most of the sick and dead pigs in pig farms are buried directly, and a small amount is burned. The method is simple and convenient, but the burial will cause bacteria and viruses to remain. Some bacillus are still infectious after decades, and incineration will produce a lot of harmful gases. , continue to pollute the environment

Embodiment 1

[0019] A harmless treatment method for dead pigs, specifically comprising the following steps:

[0020] (1) High-temperature disinfection: Collect sick and dead pigs to the treatment workshop, cut them into pieces, add tea leaves of 2% of the weight of sick and dead pigs, remove peculiar smell, smash them to a particle size of 1~2cm, put them in 190kPa high-pressure cooking for 30 minutes, put them in In the freezer, freeze at -28°C for 18 hours to obtain sterilized dead pork;

[0021] (2) Fermentation and degradation: add fermentative bacteria into sterilized dead pork, mix evenly, and ferment at 34°C for 7 days to decompose macromolecular substances, avoid the reproduction of pathogenic microorganisms, and obtain fermented dead pork;

[0022] (3) Freeze-drying: Freeze-dry fermented dead pork until the water content is 0%, remove moisture at low temperature, avoid harmful gas, save energy, and dry dead pork;

[0023] (4) Oil separation: Centrifuge dried dead pork at 50°C and...

Embodiment 2

[0031] A harmless treatment method for dead pigs, specifically comprising the following steps:

[0032] (1) High-temperature disinfection: Collect sick and dead pigs to the treatment workshop, cut them into pieces, add 2.5% of the weight of tea leaves from sick and dead pigs, remove peculiar smell, crush them to a particle size of 1-2 cm, put them in 15kPa high-pressure cooking for 35 minutes, put them in In the freezer, freeze at -27°C for 19 hours to obtain sterilized sick pork;

[0033] (2) Fermentation and degradation: add fermentative bacteria into sterilized dead pork, mix evenly, and ferment at 35°C for 7 days to decompose macromolecular substances, avoid the reproduction of pathogenic microorganisms, and obtain fermented dead pork;

[0034] (3) Freeze-drying: Freeze-dry the fermented dead pork until the water content is 3%, remove the water at low temperature, avoid harmful gas, save energy, and dry the dead pork;

[0035] (4) Grease separation: Centrifuge dried dead ...

Embodiment 3

[0043] A harmless treatment method for dead pigs, specifically comprising the following steps:

[0044] (1) High-temperature disinfection: Collect sick and dead pigs to the treatment workshop, cut them into pieces, add tea leaves with 3% weight of sick and dead pigs, remove peculiar smell, crush them, the particle size is 2cm, put them in 200kPa high-pressure cooking for 40 minutes, and put them in the freezer , frozen at -26°C for 20 hours to obtain sterilized dead pork;

[0045] (2) Fermentation and degradation: add fermenting bacteria into sterilized dead pork, mix evenly, and ferment at 36°C for 8 days to decompose macromolecular substances, avoid the reproduction of pathogenic microorganisms, and obtain fermented dead pork;

[0046] (3) Freeze-drying: Freeze-dry the fermented dead pork until the water content is 5%, remove the water at low temperature, avoid harmful gas, save energy, and dry the dead pork;

[0047] (4) Oil separation: Centrifuge dried dead pork at 55°C and...

Abstract

The invention discloses a harmless treatment method for sick and dead pigs, which includes high-temperature disinfection, fermentation degradation, freeze-drying, oil separation, and processing and utilization. The harmless treatment method for sick and dead pigs provided by the present invention is simple, efficient, completely harmless, does not use toxic chemical reagents in the whole process, does not produce harmful substances, and the prepared industrial oil and organic fertilizer do not contain pathogenic bacteria and meet national standards ;When the sick and dead pigs are sterilized by high pressure and high temperature, tea leaves are added, and the steam outlet is covered with activated carbon, which can effectively remove odors and kill pathogenic microorganisms; the sick and dead pigs are fermented by multiple microorganisms at the same time, decomposing macromolecular substances, inhibiting the growth of miscellaneous bacteria, and avoiding corruption; Freeze-drying can remove the moisture of sick and dead pork, and the oil can be separated by medium temperature centrifugation, which is fast and efficient, and the oil energy rate can reach as high as 94.3%, avoiding high-temperature cooking, protecting the environment, and saving energy; Bao, increasing economic benefits by 13.6%.

Description

technical field [0001] The invention mainly relates to the field of breeding technology, in particular to a harmless treatment method for sick and dead pigs. Background technique [0002] Any pig farm will encounter sick and dead pigs. Sick and dead pigs are usually the main source of infection for the spread and spread of diseases. They will not only cause major economic losses to the pig industry, but also seriously threaten the health of humans and animals. Effective harmless treatment. [0003] However, most of the sick and dead pigs in pig farms are buried directly, and a small amount is burned. The method is simple and convenient, but the burial will cause bacteria and viruses to remain. Some bacillus are still infectious after decades, and incineration will produce a lot of harmful gases. , continue to pollute the environment. Therefore, a truly harmless treatment is needed. Contents of the invention [0004] In order to make up for the defects of the prior art, ...
