Which is more cost-effective: a dry or wet fish feed extruder?

 

 

When choosing an extruder, "money" is an unavoidable topic. Some factories think that dry extruders are "cheaper" and buy them directly, only to end up spending a lot of electricity on drying raw materials later. Other factories choose wet extruders, which are more expensive, but the steam heating saves energy and ultimately saves money in the long run. In fact, to know which is more cost-effective, you need to calculate the "total cost," including the initial equipment cost, subsequent energy consumption costs, and maintenance costs.

 

 

Dry extruders have a relatively simple structure and do not require large auxiliary equipment such as steam boilers. Initial equipment purchase costs are typically 20%-30% lower than wet extruders. However, dry extruders rely on electric heating and powerful drying systems, requiring significant investment in supporting drying equipment and ventilation/dust removal systems. The supporting costs for a complete dry extrusion production line can account for 40% of the total equipment price. While wet extruders have a higher main unit price, they utilize steam for instantaneous material curing, requiring only a simple cooling device, with supporting costs accounting for only 15%-20% of the total equipment price. From an initial investment perspective, the "low barrier to entry" of dry extruders may conceal a higher overall cost.

 

 

Regarding energy consumption, dry extruders rely entirely on electric heating, consuming approximately 80-100 kWh per ton of feed produced. Wet extruders, using steam as a heat source and combined with a high-pressure extrusion process, consume only 40-60 kWh per ton of feed. Based on market prices, the energy cost per ton of feed is 30%-40% lower than that of dry extruders. In terms of maintenance costs, dry extruders, due to prolonged high-temperature operation, experience 30% faster wear on the screw and die compared to wet extruders, resulting in annual maintenance costs 1.5-2 times higher. While wet extruders face the risk of steam pipe corrosion, overall maintenance costs are controllable through regular maintenance.

 

 

 

 

 

Small-scale farms, due to their low output, have a clear advantage in initial investment for dry extruders, with low depreciation costs over 3-5 years. However, for medium-sized enterprises with an annual output exceeding 5,000 tons, the initial equipment price difference can be offset by savings in energy consumption and maintenance costs within 3-4 years with wet extruders. Large feed mills, if they adopt centralized steam supply systems, will see even more significant economies of scale with wet extruders, potentially reducing overall costs by 15%-20% in the long term.
