Aquatic Feed Processing Line

When we set out to design this aquatic feed processing line, we made a point to create a process that would go gentle on the feeds trying not to break any of them. This is to maintain the structural integrity of the feeds so that it would take longer for them to dissolve in water. A gentle production process produces better quality feeds to the shrimp and fish, contributing to their healthy growth.

Qidong Machinery as a global leader in the aquaculture feed industry produces all sorts of feeds to saltwater fish, freshwater fish, and shrimps. A pre-conditioning system is added to our aquatic feed processing line, placed just ahead of the extruder (pellet mill) to make feeds more suitable for subsequent processes. This process greatly improves productivity all the while reducing energy consumption.

Our aquatic feed processing line is well-known for the tender, nutritious foods it produces that are easy to chew and digest by various species of fish and shrimps, including the clown fish, catfish, flowerhorn cichlid, anglefish, betta fish, and prawn.
