With the quick growth of the tank farming industry, standard farming techniques have actually been much from fulfilling individuals's requirements. The needs for aquaculture fish feed made by fish feed extruder maker are not just balanced nourishment, good stability of the feed in water, no contamination to water quality, etc, and also much more rigid needs are advanced for the ecological high quality of fish survival.
The feed generated by the tank farming fish feed extruder machine is tough pellets, as well as the various other is the extruded feed pellet maker, and the processed fish feed is soft pellets.
Today, Richi Machinery will discuss the extruded feed fish feed extruder device. The production process typically embraces secondary squashing and also second active ingredient mixing, and after that travels through extrusion, drying, exterior spraying, cooling, squashing and also evaluating to finish the handling of aquatic extruded feed.
1. Resources cleansing as well as main grinding.
There are typically two forms of resources utilized in drifting fish feed manufacturing facilities: one is powder, which does not require to be coarsely pulverized. For this kind of basic material, it can directly enter the conical cleansing screen to eliminate impurities after travelling through the feeding pit and also elevator, and after that perform magnetic separation, and straight go into the batching container via the supplier or screw auger to join the first batching.

The material that needs to be coarsely shattered-- granular product. This sort of product gets in the cleaning devices with the discharging pit as well as the lift to enter the cleaning tools for magnetic splitting up of contaminations, and then gets in the to-be-pulverized bin.
For private raw materials, such as shrimp shells, they can be straight put into the silo to be crushed after magnetic separation without preliminary sieving.
Single rugged pulverization is the pretreatment process of ultrafine pulverization in marine feed processing. Its primary function is to minimize the pellet size difference and variation range of materials, improve the functioning problem of the ultrafine pulverizer, and enhance the functioning effectiveness as well as warranty of the ultrafine pulverizer.
The item high quality is secure; at the same time, in order to enhance the working environment of employees and also minimize cross-contamination, it is recommended to make use of an independent dust removal air web, that is, an independent dust elimination system for the feeding port.

2. The first batching and also mixing.
The very first batching is mostly the prep work of public raw materials, that is, the prep work of bigger materials in the formula. This fish feed extruder machine procedure is mainly completed by digital batching scales.
However, in the initial batching process, special attention needs to be paid to the arching issue of the batching bin, which is mostly caused by the light bulk thickness and also inadequate fluidness of the raw materials of the marine feed, particularly the top-quality aquatic feed resources. Consequently, certain anti-arching procedures ought to be considered the batching container, such as the use of eccentric discharge, resonance electric motor, etc.
The single-shaft horizontal ribbon mixer can be used for the first blending, and also the oil addition system need to be thought about on the mixer. The very first batching and mixing is likewise the pre-treatment process of ultra-fine pulverization.

This supporting equipment of fish feed extruder equipment is primarily to reduce the variant variety of material pellet dimension, boost the working condition of the pulverizer, improve the functioning efficiency of the pulverizer, and also make certain the quality of the product.
3. Secondary squashing and also mixing of additional ingredients.
As a result of the low food consumption, short gastrointestinal tract and also bad digestive system capacity of aquatic animals, marine feed needs very fine squashing pellet size to increase the area of the feed, increase the call area in between the digestion juice of water pets as well as the feed, as well as boost the capacity of aquatic pets to feed the feed.
At the same time, as a result of the reduced consumption of water animals, the blending harmony of the feed is called for to be reflected in a smaller sized range, which additionally requires the marine feed to have a finer pellet dimension.
As an example, the shrimp feed ought to all pass through the 40-mesh logical filter, and the material on the 60-mesh screen should be less than 5%, so the micro-grinding process should be adopted.
In the additional pulverization procedure, the products mixed in the first time are raised by the elevator and afterwards get in the silo to be shattered, and afterwards go into the micro pulverizer. Micro-pulverizers are usually utilized in the handling of marine feeds, and also vertical-axis micro-pulverizers are normally utilized, which are furnished with effective wind splitting up devices, and after that go into the rotary grading display for testing.

The objective of configuring the rotating grading screen right here is generally to remove the great fluff developed by the crude fibers in the feed throughout the pulverization procedure, since the presence of these great fluff is simple to stick to the die opening of the fish feed extruder device till the die hole is obstructed, creating Close down for cleaning, so it should be removed.
The cleaned up products are subjected to additional batching and mixing. Because the fineness of the products going into the secondary batching mixing bin is above 60 mesh as well as the thickness is small, unique interest ought to be paid to the phenomenon of arching.
In order to stop this phenomenon, on the one hand, the eccentric sub-expansion hopper can be made use of, as well as on the other hand, all the material discharge machines that have gone through ultra-fine grinding make use of an impeller feeder, which not just has an arch breaking device, yet additionally can flexibly readjust the flow price. size. Various resources go into the second mixer after second batching.
There is an fabricated feeding port above the second mixer, which is generally made use of for the enhancement of trace additives. At the same time, there is a fluid addition system on the mixer for the enhancement of grease; one is for the enhancement of water. In the additional mixing process, numerous products must be totally combined, as well as the coefficient of variation curriculum vitae is less than 7%, which is the crucial to guaranteeing product high quality.
For that reason, the mixer has to choose a version with exceptional efficiency, such as double-shaft horizontal paddle mixing It has high blending uniformity, high output and also rapid mixing rate. After additional squashing as well as secondary active ingredient blending, the material goes into the succeeding process-- growth granulation process-- with fish feed extruder maker.
4. Extrusion procedure by fish feed extruder maker.
In the extrusion process, the product actually undergoes a cooking procedure under the conditions of heat, high humidity as well as high pressure.
Throughout this fish feed extruder equipment process, the physical as well as chemical buildings of the material altered strongly, and also right now when the material was extruded from the die opening, the water in the feed was immediately converted from liquid to gaseous state and produced from the feed since the pressure unexpectedly dropped from high pressure to about 100kPa.
Consequently, the product is squeezed out by fish feed extruder device to form the supposed extruded feed. Because this sort of feed not only has the advantages of general tough pellet feed - good palatability, stays clear of automatic grading of items, is simple to deliver, assists food digestion, decreases waste in the feeding process, etc, but likewise has unique advantages:.
In the feed, the starch has a high degree of gelatinization by fish feed extruder maker, the protein is a lot more digestible, as well as the usage rate of the pet feed is improved; it has outstanding floatability, which is very easy to observe the feeding scenario of the fish, and also can control the water pollution to the maximum level. These are likewise the primary reasons why extruded feed is extensively used.
There are many kinds of clothes dryers can be made use of after fish feed extruder machine. When the diameter of the pellets is less than 4mm, a vibrating fluidized bed dryer can be picked; when the diameter of the pellets is greater than 4mm, a belt dryer can be picked, or a straight float clothes dryer can be directly selected.
Due to the fact that this kind of dryer can make the material in a semi-suspended state on the whole display surface, it can not just make sure the drying result, but also lessen the damages to the pellets. After the product is dried out, it goes into the exterior splashing system.
The outside spraying of the pellets is primarily to satisfy the fish's energy requirements as well as decrease the loss of heat-sensitive compounds during handling. The nutrients that must not be included the previous process can be supplemented by external splashing, and at the same time, the palatability of the feed can be boosted as well as the powder content can be lowered.
The maximum working temperature for this process is around 80 ℃. After the product travels through the external spraying system, it can go into the counter-flow colder for air conditioning.
5. Finished item packaging.
The cooled product is lifted by the lift and after that squashed right into the plane rotary display for category. The rating filter used after fish feed extruder maker is normally a two-layer filter, as well as the product on the reduced screen is the ended up item, which can be directly entered into the completed item warehouse, and then evaluated as well as packaged. The material on the upper screen requires to be returned to the crusher for crushing. The product under the reduced screen is generally carefully smashed, which can be gone back to the batching container as waste.
The fish feed extruder device manufacturing process analyzed above is the conventional arrangement of the existing aquatic extruded feed processing modern technology. Using this procedure, sinking feed, slow sinking feed as well as drifting feed can be generated.
Although extruded fish feed extruder maker technology has been acknowledged by lots of makers as a brand-new kind of processing modern technology, it has not been widely made use of because its financial investment is much larger than that of tough pellet feed handling modern technology.
However, the fish feed extruder device puffing process is the future development pattern of the feed processing industry, specifically in the application of aquatic animal feed as well as pet feed, and will definitely change the standard difficult pellet feed processing technology.
