Small scale fishery fish food extruder

Small scale fishery fish food extruder

Introduction of catfish feed pellet machine:
In recent years pelleted fish feed is becoming popular and these pelleted fish feed are commonly extruded by the fish feed extruder machine. There are dry and moist fish feed pellets. The former is more popular and the major ingredients are fishmeal made from grinding baked trash fish, fish oil, vitamins and binder. They are extruded and puffed up to produce dry pellets. Moist pellet feed is made up of fishmeal, trash fish, vitamins and binder. Pelleted fish feed is suitable for both freshwater and marine species.

Features of catfish feed pellet machine:

1.High adaptability
It is noteworthy that nutritional requirements of fish vary with different species, sizes, growth stages and feeding habits. According to these differences of fish, different moulds can be chosen to make pellets with different diameters and shapes. Both floating and sinking fish feeds can be produced by our dry type fish feed making machine. It can also be used for making pet food for dog, cat, bird, etc.
2.Advanced and durable
Advanced technology and humanized design ensure easy operation and reliable performance, high efficiency, low power consumption. Screw sleeve of this small fish food extruder adopts alloy steel strip structure, which guarantees long service life.
3.Cost-effective
Dry type fish feed extruder does not need the steam boiler, so the dry type pellet machine is cheaper and easier to use and operate compared with wet type fish feed pellet machine.
4.Outstanding performance
High temperature and high pressure increase gelatinization and the bacterial in the raw material can be killed, which make the fish feed pellets easy to digest and absorb.

Working Principles of catfish feed pellet machine:
Extruder has been used since 1960’s to treat the soybean meal in U.S.A. Extrusion means to cook the mix of ingredients under temperature, moisture and pressure in the fish feed extruder. Moisture provides lubrication for compression and extrusion and in the presence of heat causes some gelatinization of raw starch present on the surface of vegetative ingredients, resulting in adhesion. Within 20 seconds of entering the pellet mill, feed goes from an air-dry (about 10-12 percent moisture) condition at ambient temperature, to 15-16 percent moisture at 80-90°C. During subsequent compression and extrusion of holes in the die mold, friction increases feed temperature to nearly 92°C. Pellets are discharged onto a screen belt of a horizontal tunnel drier and the moisture content can be dried to below 13 percent, or into a vertical screened hopper to be air-cooled within 10 minutes to the temperature slightly above ambient temperatures.

Fish Feed Pelletizing Process
The pelleting process includes the following steps:
1. The mixed feed materials are fed into the fish feed extruder;
2. The screw presses the material;
3. Turning screw in the barrel causes a thermal energy (temperature is 110-130 °C);
4. Finally, we have cooked and well treated fish feed pellets.

Technical Parameter of catfish feed pellet machine:

The Maintenance and Conservation of catfish feed pellet machine:
Frequent and routine maintenance is the best way to keep a machine in top condition and prevent costly issues occurrence over the long term. Dry type fish feed extruder proper maintenance will ensure reliable functionality and high efficiency.
1. Add grease on the bearing in the boxes timely. After 500 hours of operation, the operator must change their grease. The proper recommended grease must be added before using the new dry type fish feed extruder. And change the grease after the first 200 hours running of the machine.
2. Add grease on other parts of the machine periodically.
3. Some wearing parts, such as screw and cover, should never be struck with a hard object. Do not stand or place heavy objects on the puffing chamber.
4. Keep the raw materials clean. Never allow any kind of metal or other foreign objects to enter the dry type fish feed machine while in operation.
5. Check the quality of extruded material. Please note the change of wearing parts.
6. If long-term shut down or replacement of extruded materials occurs, materials extruded cavity should be cleaned to prevent caking, mildew or cross contamination of materials.
7. Do not replace all of the wearing parts at the same time. Different parts of the extruder have different wearing rate.

Attentions for catfish feed pellet machine
1. Our fish feed extruder is of single screw design.
2. The pellets extruded from the fish feed pellet mill is about 80℃ and moisture content is 18%-20%, so you should equip a fish feed pellet dryer and feed pellet cooler if the capacity is more than 500kg/h. For small capacity fish feed pellet plant, the pellets can be dried under the sun.
3. We offer technical feed formula for making fish feed pellets after you place an order.

Q: What kind of floating fish food machine do we supply?

A: We have two types feed pellet machine, one is dry tye machine and the other is wet type machine. If you want to make sinking fish feed, We recommend ring die and flat die feed pellet mill .
Q: What’s the difference between dry type machine and wet type machine?
A: The biggest difference is the wet type need a steam boiler while the dry type doesn’t. In this case, the dry type is cheaper than wet type, and the feed pellets made by wet type extruder is much smooth and with better quality.
Q: What kind of raw materials should I use?
A: Soybean meal,wheat meal,corn meal,flour,bone meal,meat meal,fish meal etc.Finess in 60-80mesh.
Q: How long does the floating fish pellet float on the water surface?
A: The feed pellets made by our extruder can float on the water surface for over 24 hours. While the floating time can be adjusted when the pellets are extruded.
Q: Does the fish pellet machine can only make feed pellets for fish?
A: No. It’s not only can make high-grade aquatic feed pellets for fish, catfish, shrimps, crab etc., but also can make pellets for cat, dog, etc.
Q: What size of pellet can be made by your floating fish food machine?
A: The size of pellet is based on the diameter of the die moulds. We can customized die moulds with diameter of 1-12mm.
Q: Do you supply the fish feed production line
A: Yes. We can supply a fish feed product line include feed hammer mill, powder mixer, fish feed pellet extruder, feed pellet dryer, fish feed pellet cooler, fish feed pellet weighing and packing machine. The capacity is from 60-5000kg/h.
Q: Is there a formula of making fish feed pellet?
A: It totally based on the situation of your fish. We can offer free formula to our customers.
