Particular suitable for extruding soybean, corn and poultry feed
Wet type fish feed extruder is equipped with a boiler which can continuously providing hot steam. It can improve the digestibility and quality of the product. Feed pellets produced by fish feed pelletizer can satisfy the nutrients demands for fish like carbohy drates, protein, fat, vitamin and minerals. It also has the outstanding merits just like decreasing ingredient segregation & feed wastage, destruction of pathogenic organisms, easy storage and transportation. With high capacity and top quality products, wet type fish feed pelletizer is the wise investment in fish feeding industry!
Working Principle of the Extruder
The heart of the extruder machine working is: preconditioning, cooking and die shaping. With boiler continuously providing hot steam into the conditioner, materials can be fully cooked and the nutritional value is improved. The cooking process can cause a high level of gelatinization of starches, results in feeds with good water stability. The fish feed extruder is a long barrel with a screw auger inside which is specially designed to subject feed mixtures to high heat and steam pressure. When feed exits the die at the end of the barrel, trapped steam blows off rapidly, the soft warm pellets expand, and a low density floating pellet is produced. After that a cutting device will cut the formed pellets into different length as required. The extruder is very versatile, and can make feeds with many different characteristics.
*High efficient conditioner, stainless steel extra-long full jacketed structure, frequency control.
*Feeder with Frequency control ensures accurate feeding, stable flow, and anti-arch.
*Optional assembly main shaft can extrude different feed, especially soybean, corn, and poultry feed, as well as for rice bran, fish meal and for cotton seed meal and castor meal’s detoxication.
*High efficiency: the output is 15%-20% higher than other equivalent machines.
