Production procedure of fish feed extruder equipment

With the rapid advancement of the tank farming industry, conventional farming methods have been much from fulfilling individuals’s demands. The demands for aquaculture fish feed made by fish feed extruder equipment are not only well balanced nourishment, excellent security of the feed in water, no pollution to water top quality, etc, and extra strict needs are put forward for the environmental top quality of fish survival.

The feed generated by the tank farming fish feed extruder equipment is tough pellets, as well as the various other is the extruded feed pellet equipment, and also the refined fish feed is soft pellets.

Today, Richi Machinery will speak about the extruded feed fish feed extruder device. The production process usually adopts secondary crushing and second ingredient mixing, and after that passes through extrusion, drying out, exterior spraying, cooling, squashing and evaluating to finish the handling of water extruded feed.

1. Raw material cleaning as well as primary grinding.

There are generally 2 forms of basic materials made use of in floating fish feed factories: one is powder, which does not need to be coarsely grated. For this type of resources, it can directly get in the conelike cleaning display to remove contaminations after travelling through the feeding pit as well as lift, and afterwards perform magnetic separation, and straight enter the batching container through the distributor or screw auger to participate in the initial batching;.

The material that needs to be coarsely shattered– granular product. This kind of product goes into the cleansing equipment through the unloading pit and the lift to go into the cleansing equipment for magnetic separation of impurities, and afterwards goes into the to-be-pulverized container.

For private basic materials, such as shrimp coverings, they can be straight put into the silo to be squashed after magnetic separation without preliminary sieving.

One-time crude pulverization is the pretreatment process of ultrafine pulverization in marine feed processing. Its main objective is to reduce the pellet size difference as well as variant range of products, improve the functioning problem of the ultrafine pulverizer, as well as enhance the functioning performance as well as guarantee of the ultrafine pulverizer.

The item high quality is secure; at the same time, in order to boost the working environment of workers as well as decrease cross-contamination, it is advised to utilize an independent dust elimination air internet, that is, an independent dirt removal system for the feeding port.

2. The initial batching and mixing.

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

However, in the initial batching process, unique attention must be paid to the arching problem of the batching container, which is generally brought on by the light bulk thickness as well as bad fluidness of the raw products of the aquatic feed, especially the high-grade water feed basic materials. As a result, particular anti-arching measures ought to be taken for the batching bin, such as using eccentric discharge, vibration motor, and so on.

The single-shaft horizontal ribbon mixer can be made use of for the first blending, and also the grease addition system have to be considered on the mixer. The initial batching and blending is likewise the pre-treatment procedure of ultra-fine pulverization.

This supporting tools of fish feed extruder machine is primarily to decrease the variation variety of product pellet dimension, boost the functioning condition of the pulverizer, boost the working efficiency of the pulverizer, and also make sure the top quality of the product.

3. Secondary squashing as well as mixing of second active ingredients.

Because of the low food intake, short digestive system as well as inadequate digestive capacity of water animals, water feed requires extremely great squashing pellet size to increase the surface area of the feed, boost the call location in between the digestive system juice of marine animals as well as the feed, as well as improve the ability of water animals to feed the feed.

At the same time, as a result of the reduced intake of aquatic pets, the mixing uniformity of the feed is required to be shown in a smaller range, which likewise calls for the water feed to have a finer pellet size.

For example, the shrimp feed ought to all pass through the 40-mesh analytical screen, and also the content on the 60-mesh filter ought to be less than 5%, so the micro-grinding procedure should be taken on.

In the second pulverization process, the materials mixed in the first time are raised by the lift and then get in the silo to be crushed, and then go into the micro pulverizer. Micro-pulverizers are usually utilized in the handling of water feeds, and also vertical-axis micro-pulverizers are generally used, which are equipped with effective wind separation equipment, and afterwards enter the rotary grading display for testing.

The objective of setting up the rotating grading screen here is mostly to get rid of the fine fluff created by the crude fibers in the feed throughout the pulverization process, due to the fact that the existence of these fine fluff is very easy to comply with the die hole of the fish feed extruder device up until the die hole is obstructed, triggering Shut down for cleaning, so it has to be gotten rid of.

The cleansed products undergo additional batching as well as blending. Considering that the fineness of the materials getting in the secondary batching blending container is above 60 mesh as well as the thickness is tiny, special interest must be paid to the sensation of arching.

In order to avoid this sensation, on the one hand, the eccentric sub-expansion hopper can be made use of, and also on the other hand, all the product discharge devices that have actually undertaken ultra-fine grinding make use of an impeller feeder, which not just has an arch splitting system, yet also can flexibly change the flow rate. size. Different raw materials go into the secondary mixer after second batching.

There is an artificial feeding port above the second mixer, which is generally used for the addition of trace additives. At the same time, there is a liquid addition system on the mixer for the addition of grease; one is for the enhancement of water. In the secondary blending process, various products need to be fully mixed, as well as the coefficient of variant CV is less than 7%, which is the crucial to ensuring item top quality.

For that reason, the mixer has to choose a model with superb efficiency, such as double-shaft horizontal paddle blending It has high mixing harmony, high result as well as quick blending speed. After additional squashing and second component mixing, the product enters the succeeding process– growth granulation procedure– with fish feed extruder maker.

4. Extrusion procedure by fish feed extruder device.

In the extrusion process, the material actually undergoes a cooking procedure under the conditions of heat, high humidity and also high pressure.

Throughout this fish feed extruder machine process, the physical and chemical residential or commercial properties of the product altered strongly, and presently when the material was extruded from the die hole, the water in the feed was immediately transformed from fluid to gaseous state as well as discharged from the feed due to the fact that the pressure instantly dropped from high pressure to about 100kPa.

Thereby, the product is extruded by fish feed extruder maker to form the so-called extruded feed. Due to the fact that this type of feed not only has the advantages of general difficult pellet feed – great palatability, avoids automatic grading of products, is simple to transfer, aids digestion, decreases waste in the feeding process, etc, however also has unique benefits:.

In the feed, the starch has a high level of gelatinization by fish feed extruder maker, the healthy protein is a lot more digestible, as well as the usage rate of the pet feed is improved; it has exceptional floatability, which is very easy to observe the feeding circumstance of the fish, and can manage the water pollution to the optimum level. These are also the main reasons extruded feed is commonly utilized.

There are numerous type of dryers can be used after fish feed extruder maker. When the size of the pellets is less than 4mm, a shaking fluidized bed dryer can be selected; when the size of the pellets is more than 4mm, a belt dryer can be selected, or a horizontal float clothes dryer can be straight chosen.

Because this type of dryer can make the material in a semi-suspended state on the entire screen surface, it can not only make sure the drying out effect, but likewise minimize the damage to the pellets. After the material is dried, it gets in the outside splashing system.

The external spraying of the pellets is primarily to fulfill the fish’s power requirements and also decrease the loss of heat-sensitive compounds throughout handling. The nutrients that must not be included the previous process can be supplemented by exterior splashing, as well as at the same time, the palatability of the feed can be improved and the powder material can be reduced.

The optimum working temperature level for this procedure is around 80 ℃. After the material goes through the outside spraying system, it can go into the counter-flow colder for cooling.

5. Completed item packaging.
The cooled product is lifted by the lift and after that squashed right into the plane rotary display for classification. The rating sieve made use of after fish feed extruder device is generally a two-layer screen, and the material on the lower screen is the finished item, which can be directly participated in the ended up product storehouse, and then considered as well as packaged. The product on the top screen needs to be returned to the crusher for squashing. The material under the reduced filter is typically finely smashed, which can be returned to the batching bin as waste.

The fish feed extruder equipment manufacturing procedure assessed above is the traditional configuration of the existing aquatic extruded feed processing technology. Utilizing this process, sinking feed, slow sinking feed and floating feed can be generated.

Although extruded fish feed extruder machine technology has been identified by lots of suppliers as a brand-new kind of processing technology, it has actually not been widely used because its investment is much larger than that of tough pellet feed handling innovation.

Nonetheless, the fish feed extruder equipment blowing process is the future growth trend of the feed processing industry, especially in the application of marine animal feed as well as pet feed, and will absolutely change the conventional difficult pellet feed handling technology.
