Technical parameters of fish food extruder
Details of feed mill plant for fish
Raw materia lThe feed pellets include animal protein and plant protein. Plant protein comes from corn, rice, wheat, soybean, peanut cake powder, etc; Animal protein is from fish meal, shrimp meal, crab meal, sleeve-fish meal and so on you can add other ingredient according to requirements and eating habits of animals.
Mainly Involved processes:Material grinding, material mixing, pellets extruding, pellets drying, and pellet packing. The whole process can be highly automatically controlled.

1.Material grinding---- feed hammer mill
Raw material ingredients should be grinded to the required size by feed grinder.
2. Material mixing---feed mixer
Mixing the material thoroughly can ensure extruding efficiency and improve the feed quality. We supply two kinds of feed mixers for you to choose: double-shaft efficient mixer can be applied to mixing powdery, granular, flaky and blocky materials while feed ribbon type mixer is mostly used for mixing powdery materials. These two kinds of mixers can be customized with atomizing spraying system which will add liquid like molasses and grease to material more evenly.
3. Extruding process--- floating feed pellet extruder
Our fish feed pellet machine can be divided into two types: dry type fish feed machine and wet type feed machine. The wet type is with the conditioner and need to equip the steam boiler. The dry type fish feed extruder is cheaper while the capacity of the wet type fish feed extruder is higher, so usually the wet type fish feed extruder is suitable for large feed pellet factory and the dry type fish feed extruder is better and economic for the small and medium size user or factory.
4. Pellets drying---feed pellet dryer
Our mesh belt dryer is a continuous convective belt dryer. Pellets formed through the extruder are stacked in layers on a wire mesh or perforated plate belt conveyor and conveyed continuously through drying chambers. During this process, the drying air is passed repeatedly through the products layer until pellets have the optimum moisture content before leaving the dryer. While if you choose wet type fish feed machine, we recommend the gas type pellet dryer.
5.Pellet Coating and Cooling
If necessary, liquid fats, flavours, and vitamins can be added externally to extruded feeds after drying. Post liquid application by coating will not only avoid the risk of damaging heat sensitive ingredients, but also improve the palatability and reduce powder generation of the finished product. After coating, extruded aquafeed is cooled as required.
6. Pellet packing---packing machine
To make the finished pellets easy to store, transport and catch the clients’ eyes, they should be packed properly. With our weighing and packing machine, the finished pellets can be packed into bags, weighed, conveyed, and sealed automatically, which saves labor and time greatly and meet the requirements of large scale production. For this packing machine, automatic heat typing code, automatic bag sewing and automatic thread cutting can be optional functions.
