Feed Machine

Main features of aquatic floating feed machine

Today, aquatic floating feed machine technology is very popular in the production of aquafeeds, as it can be used to produce a variety of feeds, whether floating or sinking, depending on the needs of each species. In addition, the extruded feed made by aquatic floating feed machine has less adulteration and high efficiency, helping to improve digestibility.

During the aquatic floating feed machine extrusion process, mechanisms such as temperature, humidity, pressure will increase starch gelatinization, decompose and soften the cell wall and release some easily digestible substances, thus promoting the digestion and absorption of farmed animals.

Through aquatic floating feed machine extrusion technology, it is possible to inhibit certain protease inhibitors (such as antitrypsin), destroy pathogens in raw materials or change protein properties to further improve the contact with enzymes in fish and shrimp, helping to digest food more easily.

Extruded feed made by aquatic floating feed machine can control the content of compounds and help better detoxification. At the same time, the longer stabilization time in the water (12-36 hours) helps farmers to observe and control the feeding schedule.

Although extruded feed made by floating fish feed making machine has obvious advantages over pelleted feed, the initial investment cost of extruded feed production is higher, resulting in higher feed costs.

But for high-end fish farming, more and more people are paying attention to the market prospect of high-end fish feed.

2. The difference between pellet feed and extruded feed

With the development of the floating fish feed processing industry, two widely used technologies currently used to produce aquafeed are pelleting and extrusion by floating feed machine. Compared to natural baits, such feeds have higher nutritional content and stability, less moisture, easier storage, fewer pathogens, and longer storage times.

Pelletizing by floating feed machine is a technique of compressing small pellets of raw material into larger pellets, during which humidity, temperature and pressure can greatly affect the quality of the feed.

  • One of the main advantages of pelleted feed is lower production costs. However, it has some drawbacks.
  • One of the biggest disadvantages of pelleted feed is that it sinks faster and dissolves quickly in water (according to statistics, about 10-15% of feed is wasted), which means higher feed costs, lower farming profits, and easier cause water pollution.

3. Choose pellet feed or extruded feed?

Farmers, choose pellet feed or extruded feed?

When choosing feed, farmers should consider the characteristics of different aquatic species and feeding habits. Because the habit of shrimps and crabs is to find food at the bottom, and then eat the food slowly, so the food should not be too hard and not easily soluble in water.

Therefore, extruded sediment by floating feed machine is the best choice because it is soft and difficult to dissolve in water, and it is convenient for shrimp and crab to eat, reducing feed waste and reducing water pollution.

Especially in intensive shrimp farming, extruded feed should be dominant, because it is easier for shrimp to digest protein from extruded feed, which minimizes feed waste and promotes better protein absorption.

At the same time, we can also increase the absorption rate of the feed by adding beneficial microorganisms or stimulating digestive products to the feed.

However, from a long-term point of view, the use of extruded feed, which is made by floating feed machine will increase the cost, and if the fish use extruded feed in the mature period, it may lead to fish fat, large belly, poor stress ability, not suitable for long-distance transportation, etc. , resulting in a low price at the time of sale.

Therefore, in the process of aquaculture, when many farmers use feed, they often use a combination of pellet feed and extruded feed, which not only regulates water quality, reduces feed residues, but also improves productivity and economic benefits.

At the same time, the aquaculture industry is promoting the further development of the two feeds due to their respective advantages.

4. Installation of floating feed machine

(1) Installation of floating feed machine pipeline rack

The choice of the installation position of the pipeline rack depends on the site location, but it should not be too far from the main engine. Far from the main engine will cause waste of materials during pipeline connection on the one hand, and cause the hysteresis of the control system on the other hand.

If the installation location on site allows, the best position of the pipeline rack is to be directly behind the main engine and conditioner, parallel to the main engine, and about 1 meter away from the main engine (there is a certain maintenance space), while ensuring that the pipeline rack is adjusted upwards. The position of the steam line interface of the conditioner is on the side of the conditioner.

    In order to facilitate the cleaning of the ground and the outflow of waste water in the future, the pipe rack should be raised by about 10 cm during installation. In the installation of each valve in the pipeline, the position of the valve wheel should meet the needs of convenient operation for floating feed machine.

(2) Installation of floating feed machine control box

In order to facilitate the operation, the installation position of the on-site control box should be selected near the bypass, and a certain space should be reserved between the bypass and the control box to temporarily place the wastes flowing from the bypass.

 The distance between the frequency converter of the cutting motor and the rotary positioner of the on-site cutter should not be too far. It is controlled by voltage. If the distance is too far, it will cause voltage fluctuations and affect the cutting effect.

The circulating temperature display instrument on the on-site control box is to display the temperature of each end of the puffing cavity in real time, and the displayed temperature sequence has certain requirements. Section 2 Expansion cavity…until the material discharge expansion cavity, this sequence needs to be paid attention to when wiring the electric control.

In addition, there are 4 nozzles on the water inlet pipeline of the dual-shaft differential conditioner of floating feed machine. They control the opening of each nozzle through the electromagnetic cut-off valve.

The floating feed machine conditioner inlet nozzle switches 1 to 4 on the control box correspond to the conditioners The 1st nozzle to the 4th nozzle from the feed end.

What affect poultry feed pellet making machine pellets length?

The feed pellet size unit mainly adopts the ring die poultry feed pellet making machine, and the feed pellet size control also mainly depends on the ring die feed pellet machine.

Pellet length is an important quality evaluation index. For finished feed, the neat length can not only meet the needs of feed sales, but also meet the needs of breeding.

In practice, according to the needs of actual users and the variety of feed, the requirements for the length of pellet feed are also different. What this article is going to talk about is the four factors that affect the pellet length of RICHI feed pellet machine.

poultry feed pellet making machine

1.Yield factor.

When other parameters remain unchanged, the higher the feed pellet yield, the longer the pellet length and the shorter the pellet. Therefore, in order to meet a certain grain length requirement, it is a feasible option to adjust the output of the poultry feed pellet making machine.

In actual production, the same is true for manufacturers, sometimes sacrificing a lot of output in order to meet a certain grain length requirement.

2.The influence of ring die speed or rotation speed.

When the particle size, ring die speed, and ring die speed are inversely proportional to the pellet length, when the output is constant, the faster the ring die speed, the shorter the transient time of the generated pellets, and vice versa. For various types of SZLH series ring die poultry feed pellet making machines, the rotational speed of the ring die varies greatly. 2-12mm.

At the line speed of the ring die with small particle size, the quality of the pellets obtained is higher, but the particle size is larger. At this time, a crumbler can be added to the poultry feed pellet making machine to reduce the length of the pellets.

3.The effect of ring die aperture and porosity on pellet size.

The ring die pore size has no direct effect on the pellet length, it has an effect on the length in combination with the number of openings. The higher the opening speed of the annular die hole, the shorter the pellets and the longer the pellets. In the production of small particle size pellets.

For example, the particle size of the prepared shrimp is 1.8 mm, and the resulting pellets are too long, which is due to the low opening rate of the ring die corresponding to the small aperture.

4.Influence of ring die inner diameter, effective ring die width and particle density on particle size.

The density is related to the raw material for granulation and also to the compression ratio of the ring die, but the particle density is not very different. For the same granulation raw material, the larger the particle size obtained, the shorter the pellet length. In fact, the poultry feed pellet making machine has many uses, and it can also be used as a corn stalk pellet machine for processing cattle and sheep feed.

Can corn stalks be used as cattle and sheep feed? Listen to what the old farmers who have been farming for many years have to say?

For cattle and sheep farmers, the choice of feed is still more important. If the seriously lignified corn stalk is eaten directly by cattle and sheep, it will not only affect the digestive ability of cattle and sheep, but also cause nutrients to be absorbed by cattle and sheep normally. So can corn stalks be made into cattle and sheep feed?

Here, we will discuss corn stover feed crusher and poultry feed pellet making machine for corn stover. So what are the benefits of corn stalk feed pellet machine?

First, the corn stalk powder can be pressed into pellets by the poultry feed pellet making machine for corn stalk, and the high temperature generated by the poultry feed pellet making machine can also promote the maturation of the pellet material and increase the palatability of the feed. It is a delicious food for cattle and sheep.

I believe that many farming friends will have some questions when they see this. Why corn stover powder? Because for corn stover, its volume itself is relatively large. If the corn stalk granulator is forcibly inserted, it will not only cause serious wear and tear of the machine, but also affect the manufacturing effect.

So here is a reminder that before using the poultry feed pellet making machine for corn stalk, the corn stalks should be dried and then crushed.

Mr. Li is a professional cattle farmer who has been raising cattle for 20 years. He also has his own experience with raising cattle. Mr. Li said: “It used to be that when there were few sheep, the weeds on the hillside were enough. It was also very fresh.

The cattle and sheep ate very well. But later, the feed was not enough, so some pasture was used instead. Some forages are seriously lignified. Cattle and sheep not only grow slowly, but also suffer from indigestion after eating.

Then one day, I came out of someone’s house and saw a lot of straw piled up in the field, so I wondered if I could use the straw that others didn’t want as feed. After many inquiries, I realized that a poultry feed pellet making machine for corn stover can help with this conversion. So I tried to use a small poultry feed pellet making machine set.

The finished pellet material not only increases the feed intake of cattle and sheep, but also helps farmers in our village have no place to put straw. Kill two birds with one stone! ”

In fact, poultry feed pellet making machine is widely used as corn stover feed pelletizer. It can not only be used as cattle and sheep feed. It can also be used as animal feed for rabbits, chickens, ducks, geese, pigs, fish, pigeons, etc., with low cost of raw materials.
