أخبار الشركة عن Steps to Clean the Mold of a floating fish food making machine

Model 1: Small electric fish feed extruder machine (capacity ≤50kg/h), easy to clean and operate

The small laboratory fish feed extruder has a small die head with a simple structure, mostly an integrated die head (without disassembly components), and a fine aperture (0.5-2mm), making it easy to clean. It can be completed by a single person and is suitable for small-scale aquaculture farms and laboratories. First, the characteristics of the mold head: The mold head is relatively small (15-20cm in diameter), mostly made of stainless steel, with uniform hole diameter and no complex components. Daily residue mainly consists of loose materials and a small amount of grease, making cleaning convenient.
Second, cleaning steps: After stopping the machine, disconnecting the power, and allowing it to cool down, unscrew 2-3 fixing bolts and gently remove the mold head. Use a soft-bristled brush to remove surface dust, then use a diluted neutral detergent and a cloth to wipe away surface grease. Use a special fine-bristled brush to clean each hole, clearing them one by one. If there is slight blockage, soak for 5 minutes before cleaning. After cleaning, rinse thoroughly with clean water, allow to air dry, and then reinstall.
Third, adaptation tips: The floating fish feed extruder machine mold head has a fine hole diameter; never use hard objects to clear it. Use a small soft-bristled brush or a fine-bristled brush (appropriate for the hole diameter) for cleaning. The neutral detergent should be diluted at a ratio of 1:10 to avoid detergent residue. Do not overtighten the bolts during installation to prevent mold head deformation.

Model 2: Medium-sized automatic fish feed making machine (capacity 50-500 kg/h), routine cleaning operation

The medium-sized fish feed extruder is currently the most widely used model in the aquaculture industry. The die head is mostly modular (including die core and die plate), with a moderate aperture (2-5 mm). Residue mainly consists of material lumps and grease. Cleaning requires 1-2 people. It is suitable for medium-sized aquaculture bases and small feed mills. 1. Mold Head Characteristics: The mold head is of moderate size (20-30cm in diameter), made of high-strength stainless steel, and the mold plates are detachable with a large number of holes. During daily use, hole blockage and grease buildup on the mold plate surface are common. Cleaning requires a balance between thoroughness and component protection.
2. Cleaning Steps: After shutting down the machine and allowing it to cool, unscrew 4-6 fixing bolts, unlock the clips, and have two people work together to remove the mold head. Disassemble the mold core, mold plates, and sealing gasket. Use a soft-bristled brush and neutral detergent to clean the surface of each component. Stubborn stains on the mold plate surface can be gently scraped off with a plastic scraper. Use a special hard-bristled brush to unclog the holes. For severely clogged holes, soak them in diluted detergent for 10 minutes before cleaning. After cleaning, rinse with clean water, allow to air dry, reinstall according to the markings, tighten the bolts, and fasten the clips.
3. Adaptation Tips: Floating fish food manufacturing extruder The die head and die plates are relatively thin; avoid excessive force during cleaning to prevent deformation. Use a plastic scraper to gently remove stains, being careful not to scratch the die surface. Tighten bolts diagonally. When installing the sealing gasket, align it with the sealing groove to prevent leakage due to poor sealing.

Model 3: Large floating fish food maker machine, professional cleaning and operation

Large fish feed extruders are bulky and complex in structure. The die head is a combined heavy-duty die head (including die core, die plates, and reinforcing rings) with a large aperture (5-10mm). Residue mainly consists of stubborn material clumps, large amounts of grease, and scale. Cleaning requires 2-3 people and is suitable for large-scale feed mills. First, the characteristics of the die head: The die head is relatively large (30-50cm in diameter) and heavy (10-15kg). It is made of high-temperature resistant and wear-resistant stainless steel. The die head has many large holes, which easily accumulate stubborn scale after long-term high-load use, making cleaning difficult and requiring professional tools. Second, the cleaning steps: After shutting down the machine and disconnecting the power, and allowing it to cool down, turn off the hydraulic system (if applicable). Use an electric wrench to unscrew 6-10 fixing bolts. Two to three people should work together to remove the die head, disassemble each component, and mark it. Use a high-pressure water gun (low-pressure mode) to rinse the surface of the die head to remove floating dust and loose residue. Then use a neutral detergent and a soft brush to wipe the surface grease and stubborn stains. Stubborn clumps can be gently scraped off with a plastic scraper. Soak the holes in a special hard-bristled brush and diluted detergent for 10-15 minutes, repeatedly clearing them to ensure unobstructed flow. Clean and dry the sealing gasket separately, and check for any damage. Third, adaptation techniques: floating fish food pellet manufacturing. The machine die head is heavy, so it is strictly forbidden for one person to disassemble or clean it to avoid injury or damage from falling die head; the high-pressure water gun must be adjusted to low-pressure mode to avoid high pressure impact damaging the die head aperture; after cleaning, it must be thoroughly dried; when installing the die head assembly, it must be aligned with the positioning groove, and the bolts must be tightened evenly in a diagonal sequence; after installation, a no-load test must be performed, and production can only be started after confirming that there are no abnormalities.
