wet type floating fish feed extruder is equipped with a boiler which can continuously providing hot steam. floating fish feed extruder can produce all kinds of floating or sinking aqua feed for fish, eel, shrimp, crab, loach, bullfrog, etc, and can produce many kinds of pet feeds for cat, dog, and etc. The pellet size can be from 0.9-15mm to feed different size fishes. High capacity and top quality products, Wet type Sinking and Floating Fish Feed Extruder is a preferred choice for medium or large size feed processing factory and aquaculture farm.
Superiorities of Wet Type Fish Feed Extruder Conditioner
▶ Screw sleeve adopts jacketed construction, which can be injected in with hot steam or cooling water, thus the extruding temperature can be controlled effectively.
▶ The conditioner can make the materials have fully gelatinization of starch by a combination of hot steam and mechanical shear/mixing. The materials may remain in the conditioner for a time over 180s.
Features of Floating Fish Feed Pellet Extruder
1. The floating fish feed pellet extruder 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 Floating Fish Feed Extruder
The heart of the feed pellet 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 of Floating Fish Feed Pellet Extruder
1. Fish feed pellet extruder machine 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. the feed pellet extruder 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.
