Problems solved by technology

Chinese patent application number CN201510747024.8 puts forward the idea of ​​harmless treatment and resource utilization of sick and dead animals. Animals are hydrothermally degraded, but the patent uses plate and frame filter press to separate the solid and liquid phases of the hydrolyzate product, which requires high labor costs and the risk of spreading viruses and odors
In addition, this patent also needs to carbonize the separated solid phase and oil at 950-1300°C, which will cause problems such as exhaust pollution, high energy consumption of the process, and difficult operation.
On the whole, the entire technical process proposed by this patent is very long, with many and extremely complex separation systems, high process energy consumption, small processing capacity, and high operating costs, making it difficult to popularize and apply

Embodiment 1

[0023] Example 1: The diseased dead pigs are sent to a fully sealed crushing system for crushing, and the materials (bone, meat, hair and organs, etc.) are transported to the reactor after crushing; water and concentrated sulfuric acid are added to the materials for dissolution and sterilization, The volume ratio of material to water is 0.5:1, the amount of concentrated sulfuric acid is 10% of the material mass; seal the temperature to 100°C, maintain this temperature for 20 hours until the material is completely dissolved; reduce the reaction temperature to 40°C, Slowly add potassium hydroxide to neutralize to pH=12; after neutralization, raise the temperature to 80°C for saponification of lipids for 3 hours to obtain a reaction solution; add Bacillus subtilis at 0.2% of the mass of the reaction solution, and fully ferment Odorless brown viscous liquid was obtained. After testing, the product obtained does not contain any harmful pathogens or germs, and has a complete range o...

Embodiment 2

[0024] Example 2: The diseased dead cattle are sent to a fully sealed crushing system for crushing. After crushing, the materials (bone, meat, hair and organs, etc.) are transported to the reactor; water and concentrated hydrochloric acid are added to the materials for dissolution and sterilization. The volume ratio of material to water is 2:1, the amount of concentrated hydrochloric acid is 40% of the material mass; seal the temperature to 110 ° C, maintain this temperature for 15 hours until the material is completely dissolved; reduce the reaction temperature to 50 ° C, Slowly add potassium hydroxide to neutralize to pH = 10; after neutralization, raise the temperature to 70°C for saponification of lipids for 5 hours to obtain a reaction liquid; add 1% of the mass of the reaction liquid to add Bacillus colioids and fully ferment An odorless brown viscous liquid was obtained. After testing, the obtained product does not contain any harmful pathogens or germs, and has a compl...

Embodiment 3

[0025] Example 3: Send the sick dead dog into a fully sealed crushing system for crushing, and after crushing, the materials (bone, meat, hair and organs, etc.) are transported to the reactor; water and concentrated nitric acid are added to the materials to dissolve and sterilize, The volume ratio of the material to water is 1:1, the amount of concentrated nitric acid is 20% of the mass of the material; the temperature is sealed and raised to 120°C, and the temperature is maintained for 30 hours until the material is completely dissolved; the reaction temperature is lowered to 60°C, Slowly add urea to neutralize to pH = 9; after neutralization, heat up to 90°C for 6 hours of saponification of lipids to obtain a reaction liquid; add mycorrhizal fungi according to 0.5% of the mass of the reaction liquid, and fully ferment to obtain a Smelly brown viscous liquid. After testing, the obtained product does not contain any harmful pathogens or germs, and has a complete range of amino...

Abstract

The invention discloses a method for preparing a soil conditioner from diseased animals or inedible meat products. The method comprises the steps that firstly, disease animals or inedible meat products are smashed and then conveyed into a reaction kettle; secondly, water and acid are added; thirdly, the temperature is raised to 90-120 DEG C in a sealed state, and a reaction is carried out until all the materials are dissolved; fourthly, the reaction temperature is lowered to 40-60 DEG C, and excessive alkali is slowly added to carry out neutralization until pH ranges from 9 to 12; fifthly, the temperature is then raised to 70-90 DEG C to carry out a lipid matter saponification reaction; sixthly, 0.2-2% of beneficial bacteria are added, and the soil conditioner is obtained through fermentation. According to the method, the process of separating bones, fur and grease matter of animals is omitted, the process is short, the treatment capability is high, various disease sources and harmful bacteria are thoroughly killed, and the process is safe and clean. Animal grease is directly subjected to saponification treatment with an excessive alkali method, the separating process of the technology can be omitted, formed surface active matter can further greatly promote fusion of amino acid and microelements with soil, plants can absorb more nutritive substances, and the contact wetting action of the product on soil and plant root systems is greatly improved.

Description

technical field [0001] The invention relates to the technical field of cleaning technology for resource recovery and utilization of diseased animals or non-edible meat products, in particular to a cleaning technology method for preparing soil conditioners from diseased animals or non-edible meat products. Background technique [0002] With the acceleration of my country's urbanization process, the large-scale breeding of poultry and livestock has developed rapidly, and the number of livestock and poultry animals that die each year due to diseases and various reasons is also increasing year by year. According to the regulations in my country's "Biosafety Treatment Regulations for Diseased Animals and Diseased Animal Products GB16548-2006", dead poultry and livestock include: (1) infected animals and their products; (2) animal corpses that died of disease, poisoning or unknown causes; (3) Diseased animals and diseased animal products that have been tested to be toxic and harm...
