Long-term hazards and protection against corrosive gases. Corrosive gases such as salt (chloride ions) in the air of coastal areas and sulfides around chemical plants can severely corrode the metal components of floating fish extruder machines: First, core components rust; the anti-rust layer on the surface of steel components such as screws, extrusion chambers, and dies is corroded and destroyed, resulting in pitting and rust spots, accelerating wear, and reducing extrusion pressure and expansion effect. Second, electrical systems are damaged; corrosive gases entering the electrical control cabinet corrode circuit boards, terminals, and other components, leading to circuit breaks, poor contact, and equipment shutdown. Third, seals fail; rubber seals age and crack more rapidly in corrosive gas environments, resulting in oil and material leaks. Protective measures include: 1) Equipment protection: Regularly apply highly corrosion-resistant, food-grade anti-rust oil to the core components of the fish feed processing machine (screw, extrusion chamber); install sealed dust covers on the electrical control cabinet and place desiccants inside; 2) Environmental protection: Install dehumidifiers and air purifiers in production workshops in coastal areas to reduce air humidity and salt concentration; users near chemical plants need to set up protective isolation zones in their workshops to reduce the entry of corrosive gases; 3) Regular inspections: Conduct monthly corrosion checks on metal parts of the equipment, and disassemble and clean the electrical system every quarter, replacing corroded parts promptly. For example, a coastal aquaculture farm reduced the corrosion rate of equipment components by 70% and extended the screw's service life from 1500 hours to 2200 hours by applying salt-resistant anti-rust oil to the extruder monthly and installing air purifiers.

The hazards and optimization of poor production water quality. The steam generation and feed humidification processes of a wet fish feed extruder machine require a large amount of water. Poor water quality can cause multiple problems: First, it can clog pipes and heating elements. Calcium and magnesium ions in hard water will form scale on the inner walls of steam pipes and heating elements, leading to poor flow, reduced heating efficiency, increased energy consumption, and in severe cases, blockage and malfunction. Second, it can cause equipment corrosion. Chloride and sulfate ions in the water will accelerate the corrosion of metal pipes, causing leaks. Third, it can affect feed quality. Impurities and heavy metals in the water will mix into the feed, contaminating it and affecting the health of the fish. Water quality optimization measures include: First, installing water treatment equipment, selecting water softeners (to remove calcium and magnesium ions), activated carbon filters (to remove impurities and odors), and reverse osmosis equipment (for deep purification) according to water quality conditions to ensure that the water quality meets industrial water standards. Second, regularly cleaning pipes, descaling steam pipes and heating elements every 3 months using food-grade descaling agents such as citric acid to avoid damaging the pipes. Third, regularly testing water quality, testing hardness, chloride ion content, and heavy metal content monthly to ensure stable water quality.

Comprehensive Protection Solutions for Special Environments. For special environments where both corrosive gases and water quality issues exist (such as coastal chemical industrial zones), a comprehensive protection solution is required: First, optimize the workshop layout by installing wet pet food processing machines in areas far from corrosion sources and setting up independent raw material storage and water treatment rooms; second, strengthen equipment sealing by selecting corrosion-resistant seals and pipes (such as 304 stainless steel); third, establish a routine protection mechanism, checking equipment corrosion and pipe blockages daily, cleaning air purifiers and water treatment equipment weekly, and conducting comprehensive equipment maintenance monthly. Through comprehensive protection, the impact of corrosive gases and water quality issues can be effectively reduced, ensuring the long-term stable operation of the extruder. For example, a feed mill near a coastal chemical industrial zone reduced the extruder failure rate from twice a month to once every three months by implementing a comprehensive protection solution, extending the equipment's service life by 50%.
