Embodiment 1

[0027] Sick and dead livestock and poultry are pulverized by a pulverizer and enter the high-temperature cooking equipment through an auger. After high-temperature sterilization at 120°C and 8 atmospheres for 4 hours, the oil is refined by a centrifuge and loaded into barrels after the oil is fully stratified. After the meat slurry in the lower layer is sprayed into the mixer and mixed with the straw, the protein content in the mixture is about 15%. The black soldier fly larvae are connected to the black soldier fly larvae through the quantitative conveyor belt, and enter the transformation room for transformation. The temperature of the transformation room is controlled at 30-37°C. After 10 days of transformation, the mixture of larvae and insect droppings was separated by a vibrating sieve to obtain larvae and insect droppings. The larvae are dried in vacuum and low temperature to make fly maggot protein. According to quantitative measurement, 60 kg of dried pupa protein can ...

Embodiment 2

[0029] Sick and dead livestock and poultry directly enter the high-temperature cooking equipment, and after high-temperature sterilization at 120°C and 8 atmospheres for 4 hours, the oil will be sucked into the oil storage tank after the oil is fully stratified. The meat slurry in the lower layer is sprayed into the mixer and mixed with the bran. The protein content of the mixture is about 15%. It is connected to the housefly larvae through the quantitative conveyor belt, and enters the transformation room for transformation. The temperature of the transformation room is controlled at 30-37°C. After 4-5 days, the mixture of larvae and insect droppings is separated by a vibrating sieve to obtain larvae and insect droppings. The larvae are dried under vacuum and low temperature to make fly maggot protein. According to quantitative measurement, 62 kg of dry young pupa protein can be obtained per ton of dead livestock and poultry, and the worm manure is matured and dried to make or...

Embodiment 3

[0031] Sick and dead livestock and poultry are pulverized by a pulverizer and enter the high-temperature cooking equipment through an auger. After 4 hours of high-temperature sterilization at 120°C and 8 atmospheres, the meat slurry enters a dryer for drying, and the powder formed after drying is sent to an oil press for deoiling. Add appropriate amount of water and bran to the deoiled residue cake to mix, the water content is 70%, the protein content in the mixture is about 15%, insert EM bacteria, 37 degrees, anaerobic fermentation for 6 days, and the fermentation product is transported quantitatively Bring black soldier fly larvae into the transformation room for transformation. The temperature of the transformation room is controlled at 30-37°C. After 9-10 days of transformation, the mixture of larvae and insect droppings is separated by a vibrating sieve to obtain larvae and insect droppings. The larvae are dried under vacuum and low temperature to make fly maggot protein....

Abstract

The invention discloses an infected dead livestock disposal method. The method comprises the steps that after infected dead livestock is subjected to high-temperature sterilization and degreasing, auxiliary materials are added into meat slurry, and then the meat slurry is prepared into nourishment for breeding black soldier flies or houseflies through the enzymatic degradation step or the fermentative degradation step and the like, and utilization by the black soldier flies is facilitated. Through the process, the infected dead livestock is converted into larvae or frass of the black soldier flies or the houseflies; the larvae can be used as ingredients of high-protein feed, and the frass can be used for preparing high-quality organic fertilizer. Through the method, the infected dead livestock pollution source can be eradicated completely, and insect protein and the organic fertilizer with the high additional value can be obtained.

Description

technical field [0001] The invention relates to a treatment method for sick and dead livestock and poultry. Background technique [0002] The mortality rate of my country's pig industry is about 5-6%. Due to the large number of pigs, there are a large number of sick and dead pigs that need to be dealt with every day. The current treatment methods are mainly high-temperature incineration and high-temperature sterilization followed by composting to make organic fertilizers. These two treatment methods require large investment, low income or even no income. Some unscrupulous businesses cook dead pigs at high temperature and dry them into dry powder to sell to feed factories. This practice increases the chance of disease transmission and poses a great safety hazard to humans and animals. [0003] Domestically, a lot of work has been done on the use of black soldier flies to treat livestock and poultry manure, such as (application number -: CN2014103315855, application number -:...
