Advantages of floating fish feed pellet machine

1.Characteristics of aquatic feed

There are also multiple configurations. Floating fish feed pellet machine can process various aquatic feeds, such as ornamental fish feed, aquaculture fish feed, etc. According to the nature of fish feed products, it is divided into sinking fish feed and floating fish feed; it is an ideal equipment selection for the aquaculture industry.

Floating fish feed making machine does not require boilers, occupies a small area, and is easy to operate. It is a step-type fish feed production line with different yields, price, the daily output is 1-5 tons, which meets the production demand of 0-30,000 acre of aquaculture feed.

When choosing floating fish feed making machine, we must first understand the many characteristics of aquatic feed:

  • Small pellet size. Due to the short digestive tract of aquatic animals and related physiological characteristics, in order to speed up digestion and absorption, fish feed should be crushed with a smaller pellet size than livestock and poultry feed.
  • High in protein and low in carbohydrates. The protein content of livestock and poultry feeds is generally less than 20%, while the protein content of aquatic animal feeds is mostly 30% to 40%, and the protein content of turtle and eel feeds is as high as 65% to 70%.
  • The pellet feed made by floating fish feed pellet machine has a compact structure, high cohesiveness and water resistance. For shrimp feed, the stability of the pellet feed in water for more than 2 hours is required to produce high-quality aquatic feed. Only the use of extruded fish feed can achieve water stability sexual effect.
  • It must rely on scientific and reasonable processing technology and combine it with advanced, reliable and stable floating fish feed pellet machine. In this regard, the choice of floating fish feed pellet machine is particularly critical.

1.Why use floating fish feed pellet machine?

With the development of aquaculture in the direction of scale, intensification and specialization, its requirements for aquaculture feeds are getting higher and higher. Traditional powder compound feeds, granular compound feeds and other types of compound feeds all exist the disadvantages of poor water stability, fast sedimentation, easy to cause feed loss and water pollution, etc., have become more and more unsuitable for the development of modern aquaculture.

And extruded fish feed made by floating fish feed pellet machine solves these disadvantages, more and more aquaculture farmers and floating fish feed mill installs floating fish feed extruder machine. Wet process twin-screw floating fish feed pellet machine, the output can reach 1800-2500kg/h in one hour.

The dry process does not require a boiler. The wet process of floating fish feed pellet machine requires a boiler, with high output and uniform aging, which can be selected according to customer requirements. The raw materials are generally corn and wheat bran, and fish meal and other formulas can be added according to customer requirements.

The size range of fish feed that can be produced: 1mm, 1.5mm, 2.0mm-10mm (customized molds according to customer requirements)

Scope of application: It can produce and process catfish feed, grass carp feed, crucian carp feed, tilapia feed, ornamental fish, turtle feed, rabbit feed, bullfrog and other aquarium feed pellets. Floating fish feed, sinking fish feed.

  • lLarge-scale floating fish feed production line include automatic batching, crushing and mixing, puffing and drying, floating fish feed pellet machine, cooling and oil spraying, automatic packaging, etc.

3. What is extruded feed?

Extruded feed is a new technology of feed processing. It is a process of processing into feed through extrusion to generate high temperature and high pressure.

1.First, floating fish feed pellet machine was developed in the 1930s for the production of pasta. It was later modified to produce animal feed and human food such as snacks, candy.

Due to its high flexibility, the extrusion process can produce foods of varying degrees of fat, density, shape and size, and it can also produce a wide variety of feeds, including floating, semi-floating, and sinking feeds.

Extrusion technology of floating fish feed pellet machine has been used to produce shrimp feed since the early 1970s, but it has not been widely used because it swells after extrusion, causing the feed to float on the water for long periods of time.

In order to reduce the buoyancy of the feed, fish feed manufacturers must reduce the starch content, which leads to increased raw material costs. But with the continuous development of floating fish feed pellet machine extrusion technology. 

These shortcomings have been greatly improved, such as adjusting the design and speed of the screw, changing the configuration of the mold and the components of the vacuum heat sink. At present, it is possible to produce extruded feed for shrimp with a density equal to that of pelleted feed.

Extruded feed made by floating fish feed pellet machine can reduce the cost of raw materials to a certain extent. First, a lot of wheat starch can be replaced with cheaper starch.

2.Secondly, due to the humidity, temperature and high pressure of the floating fish feed pellet machine, easily digestible substances can be produced, which facilitates the digestion and absorption process.

After the extruded feed is expanded, it can produce a substance that improves appetite. This creates the potential to produce a more attractive shrimp feed without relying on expensive protein. Due to the continuous progress of extrusion technology, the cost of producing extruded feed is expected to be further reduced.

At the same time, the advantages of extruded feed in sterilization are unmatched by pellet feed. As a result, floating fish feed pellet machine are expected to become increasingly popular.

Formula for using poultry feed pellet making machine

Recently, I have summarized the questions of many friends and found that many people are asking about the formula of pellet feed, which is made by poultry feed pellet making machine. In fact, the raw materials and livestock and poultry used by each customer are different and cannot be generalized. Feed pellet machine formula should follow 3 principles, here are some suggestions for reference:

(1) For the customers who breed by themselves, what materials are there now?

That is to say, if you breed by yourself, you can use whatever material you used before and what material you use now. For example, you feed pigs with corn, bran, and sweet potato seedlings, then crush these three, and then use a feed pellet machine to make pellets.

(2) Pellets can be mixed with a variety of raw materials, not just one material.

In the cognition of many friends, only one material is used when using a poultry feed pellet making machine to press pellets. For example, I only use corn stover. In fact, this is not the case. You can pulverize various materials, then mix and stir, and then make granules. Pellets have always been known for their nutritious, sweet taste, so their nutrient richness is not only reflected in one aspect.

So you don’t have to think that the poultry feed pellet making machine is an artifact that is out of reach.

(3) When the pellet feed is configured, the ratio of roughage is generally 6:4.

When using a poultry feed pellet making machine to press pellets, if you have roughage in your ingredients. So we recommend you, the ratio of concentrate to roughage is 6:4. For example, you can use 60% corn, bran, 40% straw, etc. Experiments have shown that this ratio is not only conducive to the formation of particles, but also that animals eat fine and thick, especially sweet, which is conducive to livestock eating.

(4) Questions about additives.

Many friends also asked about additives. Additives are generally not required when pellets are pressed with a feed pellet machine.

Pellets have been semi-cooked during high temperature inhibition, just like people eat them. Cooked food is better than raw food. And in the granulation process, high temperature can kill many bacteria, so no additional additives are needed. Of course, it’s understandable if you want to use it. Written at the end: Different reared animals use different feed ingredients and different diets. When configuring pellet feed ingredients, it can be used flexibly and does not need to follow any principles.

The above are just some of Richi Machinery’s suggestions. In practical application, please pay attention to your actual situation.

1.How can the ring die poultry feed pellet making machine effectively prevent static electricity?

About the operation of the anti-static ring die poultry pellet machine:

(1) Before using the poultry feed pellet machine, it should be checked whether its electrostatic grounding is firm, otherwise wet grinding should not be performed.

(2) Use single grains when grinding wet powder. You need to send a bucket of wet powder from the centrifugal chamber to the grinding chamber, and then transport a bucket of water, so as to avoid concentrated accumulation of particles and avoid the concentration of acetone in the space too high.

(3) On the ring die poultry feed pellet making machine, masks, laundry gloves, anti-static underwear, and anti-static shoes can be worn.

(4) It is forbidden to collide the wet powder hammer and the stainless steel barrel with the silo of the poultry feed pellet making machine to avoid electrostatic sparks.

(5) Before grinding, check the thermometer and hygrometer beside the poultry feed pellet making machine to make sure the humidity is above 50%. If the indoor humidity is lower than 50%, it can be watered and poured before using the poultry feed pellet making machine until the indoor humidity reaches more than 50%. Otherwise, the use of poultry feed pelletizers is not allowed.

2.What is the reason why the new poultry feed pellet making machine does not feed?

The new poultry feed pellet making machine mainly uses straw raw materials to complete the granulation process. Today, poultry pellet making machines are favored by more and more users, and the number of users investing in new poultry feed machines has also increased.

However, some users’ feed pelletizers are unable to discharge. In fact, the problem that the new poultry pellet feed machine does not feed is not complicated, mainly due to the following reasons:

(1) Mold problem, the newly purchased new machine mold needs to run, so the new pellet  needs to run under the raw material with added oil (use 5 kg of feed, 1 kg of feed, 5 kg of fine sand, 2 kg of oil, or no water can be added use waste oil).

Usually the moisture of the raw material should be controlled between 4-6%. Adjust the gap between the roller and the template to about 1mm. After adjusting the roller, the fixing bolts must be tightened. (If the template hole is blocked, it needs to be opened with a hand drill before adding).

(2) Check the blade and filter. The gap between the knife edge and the filter must be suitable!

(3) The motor of the pellet  is reversed. Motors can be dangerous.

(4) Sometimes it can’t be output, and sometimes it can’t be output. Usually, this has nothing to do with forward and reverse rotation of the motor. The length of time is related to the aging degree of the pellet  template.

(5) The amount of water also has a great relationship.

(6) The compression ratio of the mold also has a great relationship.
