The capacity of twin-screw fish feed plant can reach 1-2 ton per hour. According to different production demand, the large capacity twin-screw fish feed plant has many collocations to meet the needs of different customers.

The production line mainly includes the following procedures: feeding→crushing→mixing→transferring→extrusion puffing→drying→cooling→spraying→pakacging. The raw materials is fully mixed and extruded in the twin-screw fish feed extruder, of which nutritional performance is improved by adding various nutrition. Adjusting the temperature and waster content of the raw materials to make the feed with various shape, unique taste, rich nutrition and smooth tissue. After 30-40 minutes of low temperature drying through the drier, the water content is dried to meet the quality requirements. The fish feed won’t shrink, won’t break, and its nutritional value will not be destroyed. The surface of finished fish feed after spraying has no burr that is suitable for various fish. The whole process flow is continuous and reasonable, and the performance of each machine is good, which are in most of user’s grace.

The production line applies various raw material include, such as: corn meal, soybean flour, wheat bran, meat, bone meal,etc. It is suitable for processing various fish feeds used for different fishes, and it can process different shapes of the fish feed by changing the mold, also can produce dog food, cat food and other extruded feed.

Twin Screw Extruder MachineFeatures of Large Capacity Double Screw Fish Feed Plant

High output, simple operation, convenient installation, long service life and low labor cost. The complete plant adopts the advanced frequency control system, high automation.

Fish feed has long floating time with no pollution, increasing survival rate of young fish,of which floating time can reach 20 hours. The particle diameter of the fish feed is divided into 1mm-10mm that meets the demand for feed of different stages of fish. The processed fish feed is easy to be digest by fish with no waste.

Double screw fish feed extruder can instantly kill the harmful bacteria in raw materials during the extrusion process, and decrease the water pollution. High temperature high pressure produced by twin screw fish feed extruder improves the stability and ripening of fish feed that is beneficial to the absorption of fish to feed.

Components of Double Screw Fish Feed Production Line

  1. Coarse Grinding Feed millDroplet Fish Feed Crusher

It is applicable to coarse grinding and fine grinding of the raw feed materials, such as: soybean meal, fish meal, corn, miscellaneous meal, fat, meat and bone meal, grain, etc. The range of sieve hole is 0.5 mm-10mm, and the maxim output can reach 10 ton per hour. The whole machine consists of main body, motor, fan, crushing chamber, dust collector, etc. Each part has impact structure and rational layout, having the characteristics of high output, low noise, small vibration, good performance and convenient operation. The main body is composed of three parts: rotor, upper body and lower body. The feed inlet is installed at the top of the machine with convenient operation. Crushing chamber adopts multiple stage crushing device with strong crushing effect, high efficiency. Blade cutting and high-speed airflow attack each other during production. In the processing of crushing, the rotor produces high speed airflow and rotates with the cutting direction of the blade. The raw material is accelerated in the airflow and repeatedly attacked, accelerating the grinding rate of raw material. The crusher has double crushing function that also can complete the process of micro material separation.

  1. Fish Feed Mixer

Our fish feed mixer is a new horizontal two helical-structure agitator, of which mixing shaft and the “S” shape blade are strong and durable. In order to meet the needs of different production, we have 4 types to select from, such as 300kg, 500kg, 1 ton and 2 ton. The crushed raw materials, such as corn flour, soybean meal, fish bone meal, meat powder and gluten meal, are mixed evenly according to a certain proportion. The frame and inside wall of fish feed mixer is made of stainless steel that is smooth, acid-proof alkaline, anti-corrosive and easy to clean. The screw is a kind of Internal and external reverse screw with the advantages of high mixing uniformity, higher speed and less residue. When working, on the one hand, the inner screw drives the raw material near the axis to rotate axially, and the axial force is pushed from inside to the two sides. On the other hand, the external spiral drives the material on the inside wall to rotate axially, and the axial force is pushed from both sides to the inside. The force of the stirring shaft cause the material crushed and mixed inside, so that the materials can be mixed quickly and evenly in a short time.

  1. Twin-Screw Fish Feed ExtruderTwin-Screw Fish Feed Extruder

Twin-screw fish feed extruder is the key component in this production line,  having the advantages of high expansion rate, high automation degree, strong adaptability and self cleaning function. Under the condition of high temperature high pressure and twin-screw extrusion, starch structure in raw materials start to change, then become the easily absorbed nutritional ingredient. Adjusting the rotation speed of the motor until the same size of feed particles are extruded. The fish feed is extruded through the mould and different particle sizes and shapes of fish feed can achieved by changing mould.
The capacity of twin-screw extruder can reach 0.5-1 ton per hour, especially is suitable for the production of 2-6mm floating particles. The forming rate of pellet feed is up to 99%.
