1.Double Screw Extrusion Fish Feed Production Line
a.According to different requirements, variety shapes of high-grade feed pellets for fish, shrimps .etc
b.The finished pellets can keep floating for 12 hours without pollution to water.
c.The floating time can be controlled by the puffing degree adjustment
d.Floating fish feed machine can make pellet from diameter 1mm-12mm just by changing the mould.
e.Electric heating device is adopted which can improve the feed expansion rate and pellets floating time.
f.High temperature and high pressure cooking process can kill the salmonellosis and bacterial infections and also makes the pellets easily to digest.
g.The cutting device can be adjusted to make pellets of different length.
h.The wet type machine needs a boiler to make steam which can conduct steam to the conditioner and ripen the raw material in advance.
Fish food processing line is suitable to make dry and wet type fish food pellet (catfish, aquarium, Tilapia,Freshwater fish and tropical fish etc.)
1). All fish food equipments are made of stainless steel.
2). The fish food whole line fully continuous and automatic.
3). Datongprovide basic fish food formula according to your require.
4). The final fish food shapes and sizes can be various by changing the mould.
5). Supply different size mould free of charge.
6). Packing machine could be supplied to work with the line (depending on your require).




2. Raw Materials for fish food pellet
corn flour,rice power,fish meals and other materials.Most fish food pellet inculding animal protein and plant protein. Plant protein adopts corn flour,rice flour,wheat flour,soybean flour,peanut cake powder…..Animal protein adopts fish meal, shrimp meal,crab meal, sleeve-fish meal and so on….you can add other ingredient according to the local fish living conditions.

6.Flavoring system
including hoister, flavors feed and rolling drum



1. Fish-oil or other nutritious additives are sprayed on the surface of the pellets to improve palatability and conversion rate of feed.
2. Adopting drum pattern and oil atomization spraying system together with continuous and automatic operation.
3. Widely used for spraying fat, vitamin, substrate and medication onto the surface of extrusion feed.

7.Flow of fish food production line
a. Mixer: there are many kinds of model numbers to choose base on the production capacity.
b. Conveyor: to convey mixed raw materials to the extruder machine
c.Extruder machine: to choose DSE model extruders base on the production capacity requirement from 100kg per hour to 3 ton per hour. The raw material include corn powder, cereal powder, soybean powder, shrimp powder, fish meal and     so on. Shape of the pellet depends on the moulds.
d. Hoister: to convey the fish food to the dryer, the height of the hoister depends on the dryer.
e. Multilayer dryer: electrical, gas, diesel, steam type, controlled by control box, temperature range 0-240ºC.Inside is stainless steel double layer mesh net. Drying time is adjustable according to speed. We have dryers of 3 layer 5 meter, 5 layer 5 meter, 5 layer 7 meter, 5 layer 8 meter, 7 layer 8 meter, 5 layer 10 meter, and 7 layer10 meter long.
f. Flavoring line: To spray oil and phagostimulant, the equipment are: single roller, double roller, round roller, eight-angle roller. Varies depends on the different production line setting, to spray oil to the surface of the product and make it evenly.
g. Cooling conveyor: To cool the product temperature in order to pack it directly.
h. Sifter: To remove the wasted material and shapeless pellet, and ensure quality, meanwhile to ensure the reuse of material
i. Packaging machine: Manual and automatic packing machine. weight per bag according to your requirement
