Today, Richi Equipment will discuss the extruded feed fish feed extruder machine. The manufacturing process usually embraces second crushing as well as second component mixing, and afterwards goes through extrusion, drying out, external splashing, cooling down, crushing and also screening to complete the handling of water extruded feed.

1. Resources cleansing and primary grinding.

There are generally two kinds of raw materials made use of in drifting fish feed factories: one is powder, which does not need to be coarsely grated. For this kind of raw material, it can directly enter the conical cleansing screen to eliminate impurities after passing through the feeding pit and also lift, and afterwards conduct magnetic splitting up, and also straight go into the batching bin through the distributor or screw auger to take part in the initial batching;.

The material that requires to be coarsely shattered-- granular material. This sort of material goes into the cleansing equipment via the dumping pit and the lift to get in the cleaning tools for magnetic splitting up of contaminations, and after that enters the to-be-pulverized bin.

For specific resources, such as shrimp coverings, they can be directly taken into the silo to be crushed after magnetic splitting up without first sieving.

One-time coarse pulverization is the pretreatment procedure of ultrafine pulverization in aquatic feed handling. Its main function is to decrease the pellet dimension difference as well as variant series of products, improve the functioning condition of the ultrafine pulverizer, and also boost the functioning performance as well as guarantee of the ultrafine pulverizer.

The product top quality is stable; at the same time, in order to improve the workplace of employees as well as reduce cross-contamination, it is advised to make use of an independent dirt elimination air internet, that is, an independent dust removal system for the feeding port.

2. The very first batching and mixing.

The initial batching is mainly the prep work of public basic materials, that is, the preparation of larger products in the formula. This fish feed extruder maker procedure is primarily completed by electronic batching ranges.

Nevertheless, in the very first batching procedure, special focus needs to be paid to the arching problem of the batching container, which is generally brought on by the light bulk density and poor fluidity of the raw materials of the water feed, specifically the top-quality aquatic feed raw materials. For that reason, certain anti-arching measures should be considered the batching container, such as using eccentric discharge, resonance electric motor, etc.

The single-shaft horizontal bow mixer can be made use of for the first blending, as well as the grease addition system must be thought about on the mixer. The first batching as well as blending is also the pre-treatment procedure of ultra-fine pulverization.

This supporting equipment of fish feed extruder equipment is primarily to lower the variant series of product pellet size, boost the working condition of the pulverizer, improve the working performance of the pulverizer, and also make certain the high quality of the item.

3. Second crushing and blending of additional active ingredients.

As a result of the reduced food consumption, short digestion system as well as inadequate digestive capability of marine animals, marine feed calls for really great squashing pellet size to boost the surface area of the feed, enhance the contact location in between the digestion juice of aquatic animals and the feed, and also boost the capability of marine pets to feed the feed.

At the same time, because of the reduced intake of marine pets, the blending uniformity of the feed is required to be reflected in a smaller variety, which additionally requires the water feed to have a better pellet dimension.

For instance, the shrimp feed should all pass through the 40-mesh logical filter, as well as the content on the 60-mesh screen should be less than 5%, so the micro-grinding process needs to be embraced.

In the second pulverization process, the materials mixed in the first time are lifted by the elevator and after that go into the silo to be crushed, and afterwards enter the micro pulverizer. Micro-pulverizers are generally utilized in the processing of water feeds, and also vertical-axis micro-pulverizers are typically utilized, which are equipped with powerful wind separation tools, and after that go into the rotating grading display for screening.

The purpose of configuring the rotating grading screen here is primarily to remove the great fluff developed by the crude fibers in the feed during the pulverization procedure, because the existence of these great fluff is easy to follow the die hole of the fish feed extruder equipment till the die opening is obstructed, triggering Shut down for cleansing, so it must be removed.

The cleansed products go through secondary batching and mixing. Considering that the fineness of the products going into the second batching blending bin is above 60 mesh and also the density is little, unique attention should be paid to the phenomenon of arching.

In order to prevent this sensation, on the one hand, the eccentric sub-expansion hopper can be used, and on the other hand, all the material discharge devices that have actually gone through ultra-fine grinding use an impeller feeder, which not just has an arch splitting system, however likewise can flexibly readjust the flow rate. dimension. Different resources enter the additional mixer after second batching.

There is an artificial feeding port over the additional mixer, which is generally utilized for the addition of trace ingredients. At the same time, there is a fluid enhancement system on the mixer for the enhancement of grease; one is for the enhancement of water. In the additional mixing process, numerous products should be completely mixed, as well as the coefficient of variant curriculum vitae is less than 7%, which is the vital to making certain item top quality.

Consequently, the mixer needs to pick a version with excellent efficiency, such as double-shaft straight paddle blending It has high blending harmony, high output as well as fast blending speed. After second squashing and secondary component blending, the material enters the succeeding process-- expansion granulation process-- with fish feed extruder maker.

4. Extrusion process by fish feed extruder maker.

In the extrusion procedure, the material really undertakes a cooking process under the problems of high temperature, high humidity and also high pressure.

Throughout this fish feed extruder machine process, the physical as well as chemical residential or commercial properties of the material transformed strongly, and also presently when the product was squeezed out from the die opening, the water in the feed was promptly converted from fluid to gaseous state as well as released from the feed because the pressure all of a sudden dropped from high pressure to regarding 100kPa.

Thereby, the material is squeezed out by fish feed extruder maker to form the supposed extruded feed. Since this kind of feed not just has the advantages of general difficult pellet feed - excellent palatability, avoids automatic grading of items, is easy to transfer, helps digestion, minimizes waste in the feeding procedure, and so on, but likewise has one-of-a-kind benefits:.

In the feed, the starch has a high degree of gelatinization by fish feed extruder machine, the protein is extra digestible, as well as the use price of the animal feed is boosted; it has excellent floatability, which is very easy to observe the feeding scenario of the fish, and also can control the water contamination to the optimum extent. These are also the main reasons why extruded feed is commonly made use of.

There are many type of dryers can be utilized after fish feed extruder equipment. When the diameter of the pellets is less than 4mm, a vibrating fluidized bed clothes dryer can be picked; when the size of the pellets is higher than 4mm, a belt clothes dryer can be picked, or a straight float clothes dryer can be directly picked.

Since this kind of dryer can make the material in a semi-suspended state on the whole display surface, it can not only ensure the drying out impact, however likewise minimize the damages to the pellets. After the product is dried, it goes into the outside splashing system.

The external splashing of the pellets is mostly to fulfill the fish's power requirements and decrease the loss of heat-sensitive compounds throughout processing. The nutrients that ought to not be included the previous procedure can be supplemented by outside spraying, as well as at the same time, the palatability of the feed can be improved and the powder web content can be minimized.

The optimum working temperature for this process is around 80 ℃. After the material goes through the external splashing system, it can enter the counter-flow colder for cooling.

5. Finished item packaging.

The cooled material is lifted by the lift and afterwards crushed right into the airplane rotary screen for classification. The rating filter used after fish feed extruder machine is usually a two-layer screen, and the material on the reduced sieve is the completed product, which can be straight entered into the finished product storehouse, and afterwards evaluated as well as packaged. The material on the upper sieve requires to be gone back to the crusher for squashing. The material under the reduced filter is generally carefully crushed, which can be gone back to the batching container as waste.

The fish feed extruder machine manufacturing procedure evaluated above is the traditional arrangement of the existing water extruded feed processing technology. Utilizing this process, sinking feed, slow sinking feed as well as floating feed can be generated.

Although extruded fish feed extruder equipment modern technology has been recognized by lots of manufacturers as a brand-new type of processing innovation, it has actually not been extensively utilized since its financial investment is a lot larger than that of hard pellet feed processing innovation.

Nonetheless, the fish feed extruder maker blowing procedure is the future advancement fad of the feed handling industry, particularly in the application of marine animal feed as well as family pet feed, and also will absolutely change the conventional difficult pellet feed processing technology.

I really hope the above relevant material concerning fish feed extruder equipment is practical to you. For additional information concerning drifting fish feed granulator maker, you rate to get in touch with the staff of Richi Equipment, we will serve you totally!
