1mm to 10mm twin screw extruder machine for floating fish feed
Twin Screw Extruder Introduction
Twin screw extruder is developed on the basis of single screw extruder. It has two screws of equal length placed inside the same barrel. It is born for stronger adaptability, higher capacity and better operative control. It is generally used for aquatic products and pet feed production with high added value like salmon, soft-shelled turtle and young fish feed. The high market price of these feed pellets can completely return the primary investment.
Chinese twin screw technology is quit mature. Most of domestic feed factories have used this machine to meet the latest trend. Yearmega twin screw extruder also meets the requirements of International market.
Twin Screw Extruder Features
Stainless steel DDC with 12 steam injectors and 6 liquid nozzles.
The gearbox can stand strong torque and thrust up to 400hp.
Circled tunnel design barrel with liner can achieve heating/cooling function. Steam and water can also be injected directly into the barrel.
Screw is made of special anti-wear alloy with L/D ratio up to 19.5:1 that assures smoothly production for all kinds of sinking/floating feed.
It can deal with different formulation. It can produce pellet with die diameter from 0.5 mm to 10 mm.
Fast replacing mechanism for die and screw and on-line adjustment for cutter.
Single Screw Extruder VS Twin Screw Extruder
Single Screw Extruder:
1. Belt transmission, low efficiency, difficult operation control
2. Relatively lower price, lower capacity, poor homogeneity
Double Screw Extruder:
1. Gear driving, high efficiency, flexible operation control.
2. Lower energy consumption and longer service life.
3. Wide adaptability of raw materials: high viscosity, low viscosity, high moisture, etc.
4. Fewer restrictions on the particle size of the raw materials: fine powders, coarse aggregates,etc
5. Better mixing averages, higher particle uniformity.
6. Better ripening degree, usually reaching 95%.
7. Higher yields with same power
8. Self cleaning and easy to maintain.
9. Wider diversity and adaptability of the final products

Floating fish feed processing line main processes as following:
Crushing proecss-----Mixing process-----Extruding process----Drying and oil spraying Process-----Cooling process--Packing Process
Raw Materials for Feed production
The feed pellets are usually made of corn, brown rice, paddy, sorghum and soybean meal, fish meal, bone meal etc.
Material Cleaning Sieving and Accepting Process
By receiving materials, our plant use granule cleaner and flour cleaner to clean the dust and other debris, then magnetic cylinder clean the irons and metal in the materials. After cleaned, materials be sent to next process.
Raw Material Grinding Process
General-purpose products, stable performance, widely used in large andmedium-sized feed, food processing enterprises of raw materials crushed.
The machine uses direct drive, scientific and reasonable hammer arrangement, hammer sieve clearance, finished fineness uniform. Crushing chamber second strike technology. Selection of imported high-quality bearings, low operating temperature.
A variety of screen size optional, quick open door mechanical and elastic pressure screen mechanism, for screen fast, easy operation and maintenance.
NSK bearings, SKF bearing, tungsten carbide alloy spray hammer. Bearing temperature display instrument.
Feed Material Auto Batching and Mixing Process
Dosing/Batching designs formulations according to the nutritional needs of different animals, using specific device to accurately weigh the various ingredients. Mixing is an operation in which various feed ingredients are metered and blended under external forces to form a uniform distribution. This process adopts two batching scale and a number of batching bins, of which the micro ingredients are manually added equipped with check weigher. After batching of material ingredients is completed, then enter into the mixer for mixing, and finally the material is output through the conveyor and elevator.
Weigh equipment:batching scale, batching accuracy≤3‰.
Mixing equipment:mixer SHSJ2, 1KW, 2000kg per batch, capacity 20-30T/H.
Mixing speed is short, the mixing cycle is short, 30-120 seconds / batch; mixing uniformity is high, CV ≤ 5%, and does not produce segregation;
machine mixing process is moderate, loading variable range;
Expected to meet the environmental requirements; can be equipped with compressed air cleaning system, the residue to a minimum level;
can be customized for special atomization spray system; add molasses , Grease and so more uniform;
Extruding Process
Selection of imported high-quality bearings, oil seals, to ensure that the machine running efficient, stable, low noise.
Feeder made of stainless steel, by using frequency control motor to ensure that the quality of particles discharged.
