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.
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.
◆ 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.
