supply harmless treatment equipment for slaughterhouse waste, slaughter waste treatment equipment, high temperature and high pressure

Process Flow Description:

1. Conduct surface disinfection treatment of the diseased livestock carcasses in the wetting preparation room. The treatment methods include soaking in a disinfection pool or ultraviolet disinfection, etc. Divide the ordinary diseased livestock carcasses, and then prepare for wetting. For the carcasses of major epidemic diseases, do not divide them, but prepare the whole for wetting.

2. Use the material transport vehicle to transport the diseased livestock carcasses or carcass pieces that are ready for wetting into the wetting machine, close the machine door, and at the same time close the manual interlock. Inject 0.3Mpa compressed air into the machine door sealing ring to seal the wetting machine. Then, check whether all the valves of the wetting machine are completely closed. After the check is correct, turn on the power supply of the distribution box, set the wetting temperature through the temperature controller (generally around 150°C), and then inject steam into the wetting machine. At the same time, open the exhaust valve. After about 3 minutes, the cold air in the machine is discharged. Close the exhaust valve for wetting. Under a high pressure of 0.55Mpa and a high temperature of 150°C, after a period of time, the wetting is completed (the wetting time should be adjusted by the operator according to the size and quantity of the materials being processed in the machine). At this time, it is necessary to first open the silencer valve of the deodorizer, and then open the exhaust valve of the wetting machine to release the pressure. When the pressure is released to below 0.02Mpa, close the exhaust valve and stop the pressure release.

3. Gradually open the valve between the wetting machine and the oil-water separator, and press the wetting oil-water mixture into the oil-water separator. Then, close the valve and let the oil-water mixture stand for more than 1 hour.

Open the exhaust valve of the wetting machine again to release the pressure in the wetting machine completely. Then, open the manual safety interlock, open the machine door, and transport the wetting residue out. After the residue is cooled, it enters the crusher for crushing treatment. After the crushing is completed, it is introduced into the dryer, and the power of the dryer is turned on to start the drying process. After about one hour, the drying is completed.

4. Transport the dried materials to the finished product warehouse for storage and sale.

5. One hour after the wetting is completed, open the water discharge valve of the oil-water separator to discharge the wastewater. When the oil-water boundary is 1cm lower than the oil discharge port, close the water discharge valve.

6. Open the oil discharge valve of the oil-water separator to allow the separated oil to flow into the refiner. Then, start the power of the refiner. When the oil in the refiner boils, turn off the power of the refiner.

7. Open the oil discharge valve of the refiner to allow the animal oil to flow into the container for storage and sale.
