Raw Materials for fish pellet machine
The raw material can be different kinds of the grain powder (corn powder , Flour, corn starch, rice bran), meat meal, bone meal, fish meal, soybean meal , before feeding the raw material into the extruder machine , the raw material should be 60-80 meshes with 20-25% through high temperature steam conditioning.
Why Adopt Wet Type Extruder (Advantages)
Advanced Conditioning Technology:
- the main reason of the higher price of wet type extruder is the most advanced steam conditioner. The raw materials are pre-cooked by the high temperature (130-150℃) boiler steam. The starch gelatinization can be more than 90%, which is higher than dry type extrusion.
- The high temperature boiler steam device of the aquafeed equipment improve the feed expansion rate.
Premium Pellet Quality:
- The final pellets by the wet extrusion are high gloss, smooth surface and high structural integrity. The high temperature ensures the pellets are puffed and cooked deeply. This can improve water stability more than 24 hours.
- High temperature and high pressure can kill the salmonella and bacterial infections.
- This puffing feed extrusion machine can make various grain waste into aquatic feed pellets with rich nutrition and easy digestion.
- This aquafeed equipment can produce submerged aquatic feed through changing different mold. It can eliminate the material containing most of the toxins and anti-nutritional factors of anti-trypsin and urease, Which is conducive to aquatic digestion and absorption, improve the digestion and utilization of nutrients.
High Production Efficiency:
- Although the investment is higher at the beginning, the wet type extruder offers higher production capacity up to 5 tons per hour. The high temperature steam reduces the friction between screw and sleeve, and increase their life by 30-50%. For large production, the lower energy consumption and downtime mean higher and faster return on investment.
- The main motor using high-quality Y series three-phase motor, to ensure strong power.
- The machine is engineered with an advanced pelletizing structure. It has a variable-speed, spring-loaded rotary cutter that can precisely slice pellets to round ball granules, which guarantee clean cuts and smooth edges.
- We can adjust the cutter of floating fish feed extruding machine to get different diameter and length.
When to Use Wet Type Fish Feed Extruder
| Application Scenario | Recommended Type | Reason |
|---|---|---|
| Large feed factory (>3 t/h) | Wet type | high output efficiency |
| High-quality aquafeed | Wet type | >90% starch gelatinization |
Global Projects & Proven Aquafeed Solutions
This wet type of floating fish feed extruder machine belongs to wet method type feed extruding machine for kinds of fish, which is specialized for big production capacity and big feed production factory, wet type fish feed machine is high-speed production, professional conditioning, superior pellet surface. It needs boiler steam with high temperature at 120℃ ～ 180℃. The conditioner temperature is about 120℃～140℃, but the extruding chamber temperature can reach to 130℃～180℃. And the steam presure is about 0.2～0.6 MPa. As per your requirement, you can choose to produce the exact diameter and size of the finished floating fish feed pellets. If you want high cost-effective equipment, you can check our dry type fish feed machine.
As a professional manufacturer, we are specialized in designing and manufacturing aquafeed systems for many years. And we export a lot of our floating fish feed extruding machine to all over the world, we can also provide real installation cases in different regions, These projects demonstrate that our machines are widely applied in both small farms, medium farms, and commercial feed factories. We help farmers improve feed efficiency, and help feed plants reduce feed production costs.
Our feed extrusion machine can produce aqua feed pellets with diameter from 0.9-15 mm. Besides, except floating type fish feed extruder machine, we have sinking type feed pellet mill for making sinking pellets. This aquatic feed machine can make fish feed, shrimp feed, catfish feed, goldfish feed, tilapia feed etc various aquafeed and also pet foods.
Wet type fish feed extruder machine is widely used for producing grains into high-grade aquatic feed pellets for many kinds of pet and aquatic. Grain materials employed in aquafeed system are such as wheat, soybean, cake and other leftovers and etc., moreover puffing pellets produced by the pellet extruder machine can float on the water surface without dissolution for over 24 hours. Wet type feed extrusion machine is mainly employed in medium or large size feed processing factory and aquaculture farm. For large scale production of quality pellets, it is profitable to opt wet type feed extrusion machine.

structure of Floating Fish feed extruder
1. Feeder:
It is to ensure the uniform and stable feeding, and adjust the feeding quantity according to the rated current value of the extrusion motor. Generally it uses electromagnetic speed motor or frequency converter to control speed and change material feeding quantity. The outlet of the feeding hopper is usually fed by the spiral dragline to the extruded section.
2. Extruding chamber:
It consists of a screw, a barrel, a template, a clamp and so on. The screw, and barrel are piecewise combined, so the degree of compression can be adjusted in accordance with the type and requirements of extruded feed, in order to change the expansion of the extruded feed.
3. The expansion mechanism
It is divided into 3 segments according to its function and position:
♦ Feeding section: in this section the screw pitch is large, so it mainly transports and compresses materials, so that the spiral groove is filled with feed material.
♦ Compression section: the slot of screw shallows along the material pushing direction and compresses the material.
♦ Extrusion section: screw groove is more shallow, pitch gradually turns smaller, and the extrusion pressure reaches up to 2 ～ 6 MPa, the temperature can reach 120-180 degrees.
Spare Parts For Floating Fish Feed Extruder Machine
♦ Screw sleeve adopts jacketed construction, which can be injected in with hot steam or cooling water, thus the extruding temperature can be controlled effectively.
♦ Removable cutting mechanism use knives with good elasticity, which attach to the die plate tenderly and can be operated quickly and accurately.
♦ Screw rods and dies are processed through vacuum quench treatment, also be processed with high processing precision and have a long using longevity.
♦ Due to high pressures, shear and abrasion inside the barrel of extruders, the easily-worn parts like barrel, screw periodically should be replaced. Our aqaufeed equipment are of the modular design so worn components can be easily removed and replaced as needed. Moreover, one fish feed pellet machine is equipped with extra easy wear parts for free including two sleeves, one screw, one cutting knife and three die moulds.
