Complete Livestock & Poultry Harmless Treatment Equipment Manufacturer

According to the development plans for new harmless treatment systems in many regions, the industry is prioritizing the promotion of high-temperature rendering and high-temperature fermentation technologies for resource recovery, encouraging the construction of standardized centralized treatment facilities, and phasing out outdated practices such as open-air incineration and rudimentary deep burial. Policies support integrated, turnkey equipment that combines resource recovery, harmlessness, and waste reduction, while also encouraging the intelligent upgrading of such equipment to enhance traceability and regulatory oversight.

1. Intelligent Upgrade: Install automated temperature control, pressure regulation, and data traceability systems to enable end-to-end monitoring. 2. Environmental Protection Upgrade: Add advanced equipment for exhaust gas deodorization, dioxin removal, and integrated wastewater treatment to address odor issues and exceedance of discharge standards. 3. Enclosure Upgrade: Retrofit open‑type conveying and storage facilities to ensure fully enclosed operations, thereby preventing the spread of pathogens. 4. Parameter Optimization: Validate key processing equipment parameters to ensure that temperature, pressure, and residence time meet regulatory requirements and comply with the new national standards.

1. High‑temperature hydrolysis: Moderate capital investment, with moderate energy consumption and operating‑maintenance costs; it generates revenue from the recovery of fats and organic fertilizer residues, offering high overall cost‑effectiveness and making it suitable for large‑scale operations. 2. High‑temperature incineration: High capital investment, energy consumption, and operating‑maintenance costs; no resource‑recovery benefits; used only for high‑risk emergency disposal and not appropriate for routine operation. 3. Biological degradation: Low investment and operating costs, simple maintenance, and potential revenue from organic fertilizer production; however, it suffers from low treatment efficiency and limited capacity. 4. Traditional deep burial or corpse‑decomposition pit methods: No equipment investment, but high labor costs, significant environmental risks, and no economic returns; suitable only for emergency use.

1. Rendering vessel: Prioritize stainless steel pressure‑rated, hermetically sealed vessels capable of withstanding operating conditions of at least 140°C and 0.5 MPa. Equip with real-time pressure and temperature monitoring as well as overpressure protection to ensure complete sterilization and safe operation. 2. Conveying equipment: Use a fully enclosed screw conveyor throughout the process to prevent leaks and odor dispersion, compatible with automated feeding systems; power rating should be matched to the processing capacity, ranging from 1.5 kW to 6 kW. 3. Pre‑processing equipment: Crushing equipment must accommodate various feedstocks, such as whole pigs or whole poultry, delivering uniform particle size with no large fragments remaining to ensure efficient rendering. 4. Environmental compliance: Ensure installation of exhaust gas deodorization and wastewater treatment systems that meet applicable environmental discharge standards, thereby preventing secondary pollution.

1. Pressure/temperature out of specification: Typically caused by aging tank seals or sensor malfunctions; inspect sealing components, calibrate sensing equipment, and replace aged parts. 2. Odor leakage: Resulting from inadequate sealing in conveyance lines or malfunctioning exhaust‑gas treatment systems; check pipeline integrity and service the environmental‑protection treatment system. 3. Material blockage: Caused by incomplete crushing or jamming of conveying equipment; refine pre‑treatment processes in advance and regularly clean residual material from equipment. 4. Excessive wastewater discharge: Due to clogged wastewater‑treatment filter cartridges or compromised microbial populations; promptly replace consumables and adjust treatment‑system parameters.

1. Exhaust Gases: Steam and flue gases generated during rendering and incineration must be treated using a comprehensive system that includes spray‑based deodorization, dust removal, and dioxin abatement. Once emissions meet regulatory standards, they are discharged at height, ensuring no odors and no residual harmful gases. 2. Wastewater: Wastewater from equipment cleaning and process operations is processed through an integrated wastewater treatment system; after meeting discharge standards, it is either reused or conveyed to the municipal sewer network—direct discharge is strictly prohibited. 3. Solid Residues: Rendering residues and biodegradation byproducts, following sterilization and compliance testing, may be repurposed as organic fertilizer feedstock. Incineration ash and slag, after undergoing harmless‑treatment verification, shall be disposed of in accordance with regulations via compliant landfilling or for other beneficial uses. 4. Fats and Oils: Animal fats extracted during the rendering process, after purification and sterilization, may be utilized in compliance with applicable regulations; their return to food products or animal feed is strictly forbidden.
