wet fish feed pellet processing machine vs Dry fish feed pellet extruder machine: What’s the Difference?

 

Retention of Heat-Sensitive Nutrients: Low-Temperature Lock-in vs. High-Temperature Loss. The low-temperature operation of wet floating fish feed machines (80-100℃) maximizes the retention of heat-sensitive components such as vitamins, enzymes, probiotics, and unsaturated fatty acids, achieving a nutrient retention rate of over 85%. For example, in producing aquatic feed containing probiotics, wet extruders can maintain a probiotic activity retention rate of over 70%, while the high temperature of dry extruders (120-160℃) leads to a loss of over 90% of probiotic activity, completely eliminating their immunomodulatory function. In producing feed for young animals, wet fish feed extruders effectively retain core nutrients such as vitamin C and vitamin E, avoiding negative impacts on larval growth and development-an advantage that dry extruders cannot match.

 

Starch Gelatinization and Nutrient Absorption Rate: Mild Conversion vs. Excessive Conversion. The low-temperature extrusion process of wet extruders allows for precise control of starch gelatinization at 75%-80%, ensuring easy digestion and absorption of starch molecules after recombination without damaging the nutritional structure due to over-gelatinization. This results in a crude protein digestibility rate of over 85% for farmed animals. Dry fish feed production equipment, with its high temperature and pressure, increases starch gelatinization to 80%-85%, theoretically leading to slightly higher nutrient absorption. However, excessive gelatinization can result in a harder feed texture, flavor loss, and the formation of harmful substances such as heterocyclic amines, potentially impacting animal health with long-term feeding. Furthermore, the steam humidification in wet extruders ensures more uniform nutrient mixing, avoiding the nutrient stratification and imbalance problems caused by localized high temperatures in dry extruders.

 

Palatability and Flavor Preservation: Natural Freshness Retention vs. High-Temperature Flavor Loss. The gentle processing of wet extruders preserves the inherent flavor compounds of raw materials, such as the umami components of meat and the natural aroma of grains, resulting in more palatable feed and a feed intake rate of over 95% for farmed animals. The high temperatures in dry-type floating fish feed pellet making machines can cause the flavor compounds in the raw materials to volatilize and deteriorate, and some raw materials may even develop a burnt taste, reducing palatability and requiring the addition of additional palatability enhancers. Meanwhile, feed pellets produced by wet extruders have a smooth surface, loose structure, and moderate hardness (1.5-4kg), which is suitable for the feeding needs of animals at different stages of breeding; dry extruder products, due to high-temperature extrusion, have higher pellet hardness (2.5-5kg), which poses a certain risk of damage to the oral cavity of young animals.
