          Why Choose Wet Type Fish Feed Pellet Mill

          According to your requirement and production scale, Zhengzhou Amisy Machinery can supply two types of fish feed pellet mills: dry type and wet type. However, what is difference and why choose the wet one? Please follow me to learn about pellet extrusion principle. Pellet extrusion is a process where the feedstuff is subject to mixing and heating under high pressure before being forced through a die mould. The feed constituents undergo transformations during the processing that can be beneficial as they are fully cooked and the nutritional value is improved. A temperature higher than 100 ℃ is needed in order to achieve expansion of the feed as it leaves the die. Extrusion temperature is usually a targeted value obtained through steam added in the pre-conditioner. Our wet type fish feed pellet mill is connect to a boiler which can continuously provide steam to the conditioner.
