Core Principles

The wetting machine utilizes high-pressure saturated steam (180°C, 0.9MPa) in direct contact with diseased animal carcasses. When the steam condenses, it releases a significant amount of thermal energy, achieving:

1. Pathogen Inactivation: Complete eradication of pathogenic microorganisms under high temperature and pressure conditions39.
2. Material Decomposition: Melting of fats, coagulation of proteins, and simultaneous breakdown of harmful substances310.
3. Product Transformation: Processed output can be further refined into industrial oil, biodiesel, or organic fertilizer311.

II. Equipment Classification

1. By Process Principle:
   • Standalone Wetting Machine: Utilizes pure steam treatment.
   • Dry-Wet Composite Model: Combines drying processes to enhance treatment efficiency3.
2. By Material: Carbon steel or stainless steel, with the latter offering superior corrosion resistance3.
3. By Processing Capacity: Models range from 500kg to 8 tons, catering to various scale requirements36.

III. Treatment Process

1. Crushing: Pre-treatment of carcasses or diseased tissues into appropriate sizes.

2. Rendering: Sterilization and decomposition of organic matter in high-temperature, high-pressure steam, with a cycle of approximately 6-8 hours3.

3. Drying: Removal of moisture to produce stable residues311.

IV. Key Parameters and Safety Configurations

• Temperature and Pressure: Standard conditions of 180°C and 0.9MPa3.
• Safety Devices: Equipped with safety valves and pressure interlock systems3.
• Automated Control: Supports preset treatment time, flow rate adjustment (normal mode 10-70L/min), and low-flow mode (2-5L/min)23.

V. Application Scenarios

• Diseased Animal Treatment: Such as carcasses infected with anthrax, foot-and-mouth disease, etc.3.
• Slaughterhouse Waste: Diseased tissues, glands, etc.6.
• Byproduct Utilization: Oil extraction, organic fertilizer production
