Problems solved by technology

[0004] 1. Ordinary manufacturers must add crusher equipment before the chemical system, and the crushed corpse will emit foul-smelling gas, causing secondary pollution;
[0005] 2. At the present stage, oil presses are used to separate oils. Pressing and separating oils makes the process complicated and increases the secondary pollution link, and the separation of oils is not complete, and the residual oils are easy to cause residues to rot
[0006] 3. There is a risk of exhaust gas leakage due to the imprecise transition between each process

Embodiment 1

[0045] Embodiment 1: as figure 1 As shown, the animal carcass harmless treatment process includes the following procedures and steps:

[0046] A. Feed crushing system;

[0047] Feeding: After the animal carcasses are transported to the factory by the harmless transport vehicle 1, the animal carcasses are automatically unloaded from the harmless transport vehicle 1 into the screw propulsion bin 2, and the screw propulsion bin 2 is gradually opened to gradually send the animal carcasses evenly Enter on the conveyor belt 3, and the conveyor belt 3 transmits the animal carcass into the chemical tank 4;

[0048] During the feeding process, open the stirring shaft 6 and the steam valve 10 of the chemical tank 4, input steam into the interlayer 5 and the shaft, make the steam pressure in the interlayer 5 and the shaft reach 0.4 MPa, and turn on the vacuum pump 7 to suck the steam in the tank to condenser 8;

[0049] After the feeding is finished, close the 4 mouths of the chemical...

Embodiment 2

[0068] Embodiment 2: as figure 1 As shown, the animal carcass harmless treatment process includes the following procedures and steps:

[0069] A. Feed crushing system;

[0070] During the feeding process, open the stirring shaft 6 and the steam valve 10 of the chemical tank 4, input steam into the interlayer 5 and the shaft, make the steam pressure in the interlayer 5 and the shaft reach 0.5 MPa, and turn on the vacuum pump 7 to suck the steam in the tank to condenser 8;

[0071] After the feeding is finished, close the 4 mouths of the chemical tank, and the animal carcasses in the tank will be decomposed after being heated, and the pressure in the tank will gradually increase, so that the pressure in the tank will rise to 0.3 MPa, and the temperature will reach about 140 °C;

[0072] When the pressure in the tank reaches 0.3 MPa, stop the stirring shaft 6, close the steam in the interlayer 5 and the shaft, and make the tank static for stratification for about 30 minutes.

Embodiment 3

[0076] Embodiment 3: as figure 1 As shown, the animal carcass harmless treatment process includes the following procedures and steps:

[0077] A. Feed crushing system;

[0078] During the feeding process, open the stirring shaft 6 and the steam valve 10 of the chemical tank 4, input steam into the interlayer 5 and the shaft, make the steam pressure in the interlayer 5 and the shaft reach 0.6 MPa, and turn on the vacuum pump 7 to suck the steam in the tank to condenser 8;

[0079] After the feeding is finished, close the 4 mouths of the chemical tank, and the animal carcasses in the tank will be decomposed after being heated, and the pressure in the tank will gradually increase, so that the pressure in the tank will rise to 0.3 MPa, and the temperature will reach about 150 °C;

[0080] After the pressure in the tank reaches 0.3 MPa, stop the stirring shaft 6, close the steam in the interlayer 5 and the shaft, and make the tank static for stratification for about 60 minutes. ...

Abstract

The invention provides a process for harmless treatment of animal carcasses, which is characterized in that it comprises the following steps: A, feeding and crushing; B, separating oil and fat; C, depressurizing; D, vacuum drying; E, cooling; F, Package. The animal carcass harmless treatment process of the present invention has the functions of crushing, refining, oil separation, and vacuum drying. Layered separation, the secondary separation of grease meets the requirements, avoiding the pollution of the surrounding environment between process transitions, reducing energy consumption in each process, and materials can be reused after treatment, energy saving and environmental protection.

Description

technical field [0001] The invention relates to a treatment method for animal corpses, in particular to a harmless treatment process for animal corpses. Background technique [0002] Animal carcasses, regardless of whether they died normally or died of epidemic diseases, often carry a variety of germs. If they are not handled or handled improperly, the carcasses will quickly decompose and emit odors, causing pathogenic microorganisms to pollute the air, water and soil, resulting in the spread of diseases and People who have direct or indirect contact with it may be infected. This requires timely treatment to prevent the growth of bacteria and the spread of diseases, that is, the harmless treatment of animal corpses. [0003] The traditional animal carcass treatment process has the following defects: [0004] 1. Ordinary manufacturers must add crusher equipment before the chemical system, and the crushed corpse will emit foul-smelling gas, causing secondary pollution; [0...
