company news about Proper Methods for Loading Materials into an automatic fish food making equipment

Problem 1: Raw material jamming, feeding interruption. This is the most common problem when loading small fish food making machines. The main causes include excessive moisture content (over 15%), uneven particle size, excessive impurities, or residual raw material adhering to the feed inlet and conveyor pipe walls. It could also be due to a jammed screw conveyor or a malfunctioning feeding device. Solutions: Immediately stop the machine and disconnect the power. Do not force the equipment to start. Manually clear the jammed area. Use wooden tools to unclog the feed inlet and conveyor pipes, removing impurities and dried raw material. If the screw conveyor is jammed, check for foreign objects blocking the blades or bearing wear causing the jam. Remove foreign objects and repair or replace the bearings. After cleaning, check the pre-treatment status of the raw materials. Dry any excessive moisture, screen for uniform particle size, and then restart loading. Prevention tips: Strictly control raw material pre-treatment standards. Clean residual raw materials from the feeding system before loading. Regularly check the conveyor and feeding device to avoid potential malfunctions.

Problem 2: Uneven loading of fish pellet making machines, leading to fluctuations in puffing degree and abnormal discharge. The main causes include chaotic manual feeding rhythm, unbalanced parameters in the automatic feeding system, malfunctioning level sensors, unstable screw conveyor speed, and poor raw material flowability or localized agglomeration. Countermeasures: When manually feeding, adjust the feeding rhythm, using a "small amount, multiple times" method for even feeding, and use a feeding tool to ensure smooth feeding. When automatically feeding, calibrate the sensitivity of the level sensor, adjust the feeding speed parameters, tighten the screw conveyor frequency converter, and stabilize the speed. If the raw material is agglomerated, it needs to be re-crushed and screened, and an appropriate amount of flow aid should be added to improve flowability. Simultaneously adjust the extruder parameters to stabilize the screw speed and extrusion temperature, and resume the normal feeding rhythm after the output is uniform. Prevention techniques: Check the uniformity of the raw material before feeding, standardize the manual feeding rhythm, and regularly calibrate equipment parameters and sensors for automatic feeding to ensure accurate linkage control.

Problem 3: Overload of the small floating fish feed making machine, resulting in motor overheating and abnormal noise. The main causes are excessively fast loading speed, exceeding the extruder's processing capacity, leading to excessive pressure in the extrusion chamber and excessive stress on the screw; it could also be due to excessive impurities in the raw material, causing the screw to jam, or insufficient preheating of the equipment during loading, resulting in low-temperature raw material adhering to the extrusion chamber. Countermeasures: Immediately stop the machine, disconnect the power, and after the equipment cools down, clean the raw material and impurities from the extrusion chamber, and check for wear on the screw and die; after cleaning, reduce the loading speed (manually reduce the feed rate, automatically adjust the feed speed parameters), start the equipment under no-load preheating to the set temperature, and then gradually resume loading, observing the motor load and equipment operating status. Prevention techniques: Preheat the equipment to the rated temperature before loading, strictly match the loading speed with the extruder's capacity, avoid overloading, and ensure proper impurity removal of the raw material to protect the screw and die.

Problem 4: Raw material leakage in the small fish feed maker machine, leakage at the feed inlet and pipe connections. The main causes include loose bolts at the connection points, aging and damaged seals, or overloading of the feed hopper and pipeline, leading to material overflow; it could also be due to material splashing during loading, causing leakage. Countermeasures: Stop the machine and tighten the bolts at the connection points; check for aging and damaged seals and replace them promptly; control the feeding rate to avoid overloading and overflow of the feed hopper and pipeline; if material splashing occurs, install a protective baffle at the feed inlet and adjust the loading rhythm to prevent excessively rapid feeding that could cause splashing. Prevention techniques: Check the bolts and seals at the connection points before loading; regularly replace aging seals; control the loading rate and rhythm; install protective devices to reduce the risk of leakage and splashing. In addition, implement leak-proof measures in the loading area, placing a receiving tray to avoid material waste and environmental pollution.
