What are the hidden killers affecting the quality and yield of extruded fish feed?

 

 

Some feed mills, even with seemingly standardized operations, still experience declining quality and fluctuating output during production. In fact, negligence in equipment maintenance and improper control of the production environment are like hidden "killers," silently affecting the quality and yield of extruded fish feed.

 

 

 Impact on Equipment and Quality: Component Wear and Tear, Deteriorating Feed Quality
Failure to replace worn extruder cutters in a timely manner results in feed pellets of inconsistent length and substandard appearance. Wear on the die causes a rough feed surface, even creating holes, affecting palatability and water stability.

 

For example, feed that could previously remain in water for 8 hours may have its stability reduced to 4 hours due to die wear, leading to poor feedback from farmers.Uncalibrated internal temperature sensors cause discrepancies between the actual and set temperatures in the barrel, resulting in abnormal starch gelatinization, unstable feed extrusion, and a drop in the pass rate from 90% to 80%.

 

 Impact on Output: Sudden Failures, Forced Production Interruptions
Lack of regular lubrication and maintenance increases friction in transmission components, increasing equipment operating resistance. This not only increases energy consumption but also increases the risk of sudden failures such as belt breakage and bearing seizure. Statistics show that downtime due to insufficient equipment maintenance reduces effective production time by an average of 10-15 hours per month, resulting in a capacity reduction of approximately 15%.

 

Proper Operation: Develop a maintenance plan and perform regular deep maintenance.

After daily production, clean the equipment surface and inspect the wear of vulnerable parts such as cutters and molds; lubricate and maintain transmission components weekly, replacing severely worn belts; calibrate and test the equipment's sensors and temperature control system monthly.

Establish equipment maintenance records, detailing the time, content, and problems found for each maintenance session, to track equipment status promptly and prevent malfunctions in advance.

 

 

Impact on Quality: Uncontrolled Temperature and Humidity Threaten Feed Quality
High temperatures in the production workshop (above 35℃) accelerate the oxidation of oils in raw materials, causing rancidity and affecting palatability. Simultaneously, high temperatures lead to excessive starch gelatinization, making the feed easily soluble in water and reducing its stability. Conversely, high humidity (relative humidity exceeding 70%) causes raw materials to easily become damp and clump together, leading to blockages during extrusion and increasing the likelihood of mold and spoilage in the produced feed.

 

For example, during the rainy season, feed mills that haven't implemented proper moisture control measures have produced feed with mold exceeding the standard rate of up to 10%, necessitating scrapping and wasting raw materials.

 

Impact on Output: Dust Accumulation and Reduced Equipment Efficiency
Large amounts of dust generated during production, if not cleaned promptly, will accumulate on electrical components and transmission parts of the equipment, affecting heat dissipation and normal operation. Dust entering precision components such as bearings will accelerate wear; accumulation in electrical cabinets may also cause short circuits. It is estimated that equipment failures due to dust problems can reduce production capacity by 8%-10%.

 

Proper Operation: Optimize the Environment to Ensure Stable Production

Install temperature and humidity control equipment in the workshop, maintaining the temperature between 20-30℃ and the relative humidity between 40%-60%; equip the workshop with professional dust removal equipment, and regularly clean the workshop and equipment, especially critical areas such as electrical cabinets and transmission components.

 

Strengthen the management of the raw material storage environment, ensuring the warehouse is dry and well-ventilated, and storing raw materials off the ground and away from walls to prevent moisture absorption and spoilage.
