Double Screw Extruder

1. Extruder is mainly composed of feeding, pre-conditioning, extrusion and cutting systems.
2. Main engine adopts inverter to adjust speed of screw according to changing of formula. 
3. adopt building block system (BBS) to be adjustable for different technology. 
4. Double-shaft pre-conditioner makes excellent result of mixing and conditioning, increasing capacity of extruder 10-15%.
5. Diameter of feed 1mm to 12mm can satisfy feed production for dog, cat, tortoise, bird, sea fish, shrimp and pet fish etc.
6.Self-cleaning, when stopping, it can be cleaned without disassembling.

Main parts of the wet type twin screw extruder:

Application scope: Food industry,Feedstuff,Agricultural Products, Application Grain,Pet Food,Fish Feed,Puffed Snacks,Soybean Chunk,Pasta,Artificial rice,Vegetarian Meat,Etc

Flavoring system

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.

Formation of dog food production line:

1. Mixer: there are many kinds of model numbers to choose base on the production capacity.
2. Conveyor: to convey mixed raw materials to the extruder machine
3.Extruder machine: to choose DSE model extruders base on the production capacity requirement from 100kg per hour to 3ton 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.
4. Hoister: to convey the fish food to the dryer, the height of the hoister depends on the dryer.
5. 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 layer 10 meter long.
6. 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.
7. Cooling conveyor: To cool the product temperature in order to pack it directly.
8. Sifter: To remove the wasted material and shapeless pellet, and ensure quality, meanwhile to ensure the reuse of material
9. Packaging machine: Manual and automatic packing machine. weight per bag according to your requirement.
