Dead animals and poultry harmless treatment process introduced:
In order to prevent the spread of animal diseases, the protection of public health and safety, and promote the healthy development of animal husbandry, to promote the majority of farmers can consciously harm the livestock and poultry harmless treatment, do a good job in large-scale pig farm harmless treatment related work The process of careful and meticulous handling of sound treatment.
In the implementation of the treatment of livestock and poultry harmless treatment, animal husbandry cadres in the audit submitted to the material to the four major off: First, a good photo off, ask the farmers in the filming of livestock and poultry photos have a unified standard to prevent Individual farmers and more animals according to the situation, to prevent the camera in the process of fraud. And asked the picture must be clear, the whole pig photo complete. The second is to keep a good number of numbers, the requirements of the pig on the death of more than 5, or the death rate of more than the normal range of time to the township (town), the street report, and farmers livestock and poultry mortality rate of more than 10% of the written instructions The Three is a good material audit off, require farmers to remember a good culture file, the establishment of dead pigs "daily processing account." Fourth, the good supervision, requiring farmers according to the laws and regulations to implement the relevant provisions of the harmless treatment system, do not kill, do not sell, do not eat, do not transport, do not discard dead pigs (livestock), and local deep Or in a harmless treatment pool. The company uses high-temperature sterilization, negative pressure adsorption disinfection technology for the dead livestock and poultry litter, excreta and contaminated feed for the accumulation of fermentation, for harmless treatment. Consciously accept the local animal husbandry and veterinary area management station supervision and inspection. For the number of false dead pigs, cheating subsidies to cancel all policy to enjoy.
First, the livestock and poultry harmless treatment equipment principle and process:
Harmless treatment equipment principle: small dry method to deal with the unit is the organic waste through high temperature and pressure (135 ¡æ, 0.3Mpa) way effective sterilization, while the use of negative vacuum vacuum drying the object, and then in the Degreasing, and ultimately produce full-fat meat and fat, to achieve the full recovery of waste and efficient use of the results.
Harmless treatment equipment process: animal body transport feeding → high temperature and high pressure crushing, sterilization, drying, pressure relief and waste gas treatment → degreasing → packaging, storage.
1,dead animals and poultry by a dedicated closed dump truck, the sick pig and slaughter plant physical death pig transported to the harmless treatment plant.
2,the material through the belt conveyor or hoisting machine sent to the machine, the process of automatic operation, to avoid the secondary pollution of bacteria.
3,the material is filled, close the mouth, the heating step up sterilization, the tank temperature reaches 135 degrees (0.3Mpa), the pressure to maintain 30 minutes (Europe and the United States sterilization standards, but also according to different materials to adjust the pressure and temperature) , And then into the drying stage, the use of low-temperature vacuum drying method, dry 3-4 hours (according to the different material moisture to adjust the drying time), the material moisture content dropped to 10-12%, about 30%.
4,open the mouth, meat and bone meal through the screw conveyor to the screw press machine, through the principle of the spiral press the oil separation, the oil content of 10-12% (to feed the oil standard) of the meat and bone meal, grease.
5,the process of drying, the resulting exhaust gas, after the dust regulator dust, into the water-cooled condenser, the high-temperature water vapor condensed into water, condensed gas directly after the discharge.
6,in the drying process of waste water for the waste gas does not contain oil, the main harmful ingredients CODcr, bod, ammonia, can be directly through the closed pipe into the sewage treatment plant for centralized treatment.
Second, the livestock and poultry harmless treatment equipment Small dry method to deal with the unit Name:
1.Convection tank: the tank with internal automatic mixing teeth, can be directly into the dead pigs, without dismemberment, the product set broken, chemical, sterilization, drying integration.
2.Spiral oil press: for the drying of meat and bone meal after the degreasing, meat and bone meal to achieve the separation of fat.
3.Screw conveyor: for the drying of meat and bone meal after the transfer between the oil and oil press.
4.Extinguisher: Exhaust gas treatment equipment, the high temperature and high pressure treatment, the pressure relief and drying process of dust on the buffer dust, to avoid pressure when the material attached.
5.Condenser: exhaust gas treatment equipment, the condensate condensed into water, centralized collection and treatment.
6.Vacuum pump station: chemical drying process, through the vacuum pump station to complete the vacuum control, water level control, drainage control and other links, to achieve the internalization of low-temperature negative pressure drying tank, with sewage collection tank.
7.cooling tower, water tank; circulating cold water, rechargeable condenser required cold water.
