The diesel engine offers better adaptability to purchase costs and usage scenarios. In remote aquaculture areas without power grid coverage or where grid upgrades are expensive, electric-powered feed extruders require generators or grid construction, with additional investments often exceeding the equipment's price. Diesel models, on the other hand, require no such additional investment and are ready to use immediately after setup and commissioning, making initial investment more controllable. For example, a 500kg/hour capacity diesel engine costs approximately 80,000 yuan, while an electric-powered model, requiring a 100kW generator, would cost over 120,000 yuan. Furthermore, diesel engines retain their resale value better; after three years, the resale price can still reach 40% of the original price, 15 percentage points higher than electric-powered models, reducing losses from equipment replacement.

The diesel engine also offers superior flexibility and economy in operating costs. While diesel and electricity prices vary across regions, diesel-powered feed extruders can benefit from bulk diesel purchases, enjoying price discounts, especially with agricultural fuel subsidies, resulting in a more significant operating cost advantage. Actual data from a fish farm shows that in areas with industrial electricity prices of 1.2 yuan/kWh and diesel prices of 7 yuan/liter, the power cost of producing one ton of feed using a diesel engine is approximately 120 yuan, 33% lower than the 180 yuan for an electric engine. More importantly, diesel engines can flexibly adjust production time according to feed demand, producing and storing feed in bulk during periods of low diesel prices, further reducing costs; while electric engines are affected by peak-valley electricity price differences, limiting cost control.

The low maintenance cost and ease of operation of the extruded floating fish feed pellet machine are long-term advantages. Diesel engines have a mature structure and low technical barriers to maintenance; most fish farmers can complete daily maintenance with simple training, without relying on professional repair personnel. Its easily worn parts are mainly filters and belts, which are widely available and inexpensive, with replacement costs only 1/5 of the motor maintenance cost for an electric engine. Statistics show that the average annual maintenance cost of a diesel engine is approximately 2,000 yuan, saving 60% compared to the 5,000 yuan for a similarly sized electric engine. Meanwhile, diesel engines have a service life of 8-10 years, longer than electric motors (5-6 years), further reducing the amortization cost of equipment per unit of feed.
