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 carbohydrates, 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!

Features of Floating Fish Feed Pelletizer
1. The pelletizer can produce puffing fish feed pellets floating on the water surface without dissolution for over 12 hours; fish feed pellet size can be from 0.9-15mm
2. High temperature and high pressure process can kill the salmonellosis and bacterial infections and also makes the pellets easily to digest.
3. Electric heating device is adopted to improve the feed expansion rate and pellets floating time.
4. Key parts are processed through vacuum quench treatment with high processing precision, thus have a long service life.
5. Variably configurations of screw bolts can match the producing demands for different formulas and raw materials.
6. Single-screw extrusion cooking: capable of high production capacities; variable screw speeds
7. Change different molds to make pellets with different diameters.

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.

Wide Application
1. Fish feed extruder can produce fish feed pellets for fish, eel, shrimp, crab, loach, bullfrog, etc, and can produce many kinds of pet feeds for cat, dog, and etc.
2. It is mainly employed in medium or large size feed processing factory and aquaculture farm.
3. The raw materials can be wheat, soybean, cake and other leftovers etc. Its main work principle is changing mechanical energy into heat energy to extrude material.

Attentions
◆ Our fish feed extruder is of single screw design.
◆ The pellets extruded from pellet mill is about 80℃ and moisture content is 18%-20%, so you should equip a dryer and cooler if the capacity is more than 500kg/h. While for small capacity, you can dry them in the sun.
◆ We provide technical formula for making floating fish feed pellets after placing order.
◆ We send extra easy wear parts for free including two sleeves, one screw, one cutting knife and three die moulds.
