With the rapid development of the tank farming sector, traditional farming techniques have been far from meeting people's needs. The needs for aquaculture fish feed made by fish feed extruder device are not only balanced nourishment, great stability of the feed in water, no pollution to water high quality, etc, and a lot more rigid demands are put forward for the ecological quality of fish survival.
The feed produced by the tank farming fish feed extruder machine is hard pellets, and the various other is the extruded feed pellet equipment, as well as the refined fish feed is soft pellets.
Today, Richi Equipment will speak about the extruded feed fish feed extruder machine. The production procedure normally embraces additional crushing and additional component mixing, and then travels through extrusion, drying, external spraying, cooling down, crushing as well as evaluating to finish the handling of water extruded feed.

1. Resources cleaning and also key grinding.
There are typically 2 forms of resources used in drifting fish feed manufacturing facilities: one is powder, which does not require to be coarsely grated. For this sort of resources, it can directly enter the conical cleansing display to eliminate impurities after travelling through the feeding pit as well as elevator, and after that conduct magnetic splitting up, as well as straight enter the batching container through the supplier or screw auger to take part in the very first batching;.
The product that needs to be coarsely crushed-- granular product. This sort of product goes into the cleaning tools via the dumping pit as well as the lift to go into the cleansing equipment for magnetic splitting up of contaminations, and afterwards enters the to-be-pulverized bin.

For individual raw materials, such as shrimp shells, they can be straight put into the silo to be squashed after magnetic splitting up without first sieving.
One-time crude pulverization is the pretreatment process of ultrafine pulverization in water feed processing. Its main purpose is to reduce the pellet size difference and variation series of products, improve the functioning problem of the ultrafine pulverizer, as well as enhance the working efficiency as well as assurance of the ultrafine pulverizer.
The item top quality is stable; at the same time, in order to improve the workplace of workers and reduce cross-contamination, it is suggested to utilize an independent dirt removal air web, that is, an independent dust removal system for the feeding port.
2. The first batching as well as mixing.
The initial batching is mostly the prep work of public resources, that is, the preparation of larger materials in the formula. This fish feed extruder machine process is mostly completed by electronic batching ranges.

Nevertheless, in the initial batching process, special focus should be paid to the arching issue of the batching bin, which is generally triggered by the light bulk thickness and poor fluidness of the raw materials of the aquatic feed, specifically the top-quality water feed raw materials. Consequently, certain anti-arching procedures should be considered the batching container, such as using eccentric discharge, vibration electric motor, etc.
The single-shaft horizontal ribbon mixer can be used for the first blending, and the grease addition system must be thought about on the mixer. The initial batching and also mixing is additionally the pre-treatment procedure of ultra-fine pulverization.
This supporting tools of fish feed extruder equipment is generally to reduce the variant range of product pellet dimension, enhance the functioning problem of the pulverizer, boost the working effectiveness of the pulverizer, as well as guarantee the top quality of the item.
3. Secondary squashing as well as blending of additional components.
As a result of the reduced food consumption, short digestive system tract and also bad gastrointestinal capability of aquatic pets, marine feed requires really great squashing pellet size to increase the surface of the feed, enhance the call area in between the digestive juice of water animals and also the feed, and improve the ability of marine pets to feed the feed.
At the same time, because of the low consumption of aquatic pets, the mixing harmony of the feed is needed to be shown in a smaller array, which additionally requires the aquatic feed to have a finer pellet dimension.
As an example, the shrimp feed must all travel through the 40-mesh analytical screen, as well as the material on the 60-mesh sieve must be less than 5%, so the micro-grinding procedure needs to be embraced.

In the second pulverization procedure, the materials mixed in the first time are raised by the lift and afterwards get in the silo to be shattered, and after that go into the mini pulverizer. Micro-pulverizers are normally utilized in the processing of marine feeds, as well as vertical-axis micro-pulverizers are generally used, which are outfitted with effective wind separation tools, and then enter the rotary grading display for screening.
The function of setting up the rotating grading display here is primarily to remove the great fluff formed by the coarse fibers in the feed throughout the pulverization process, due to the fact that the existence of these great fluff is simple to adhere to the die opening of the fish feed extruder maker up until the die hole is obstructed, creating Close down for cleansing, so it must be eliminated.
The cleaned up products go through additional batching as well as mixing. Considering that the fineness of the materials getting in the additional batching mixing bin is above 60 mesh and also the density is little, unique attention must be paid to the sensation of arching.
In order to stop this sensation, 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 makers that have actually undertaken ultra-fine grinding utilize an impeller feeder, which not just has an arch breaking device, but also can flexibly adjust the circulation price. size. Different raw materials get in the additional mixer after additional batching.
There is an artificial feeding port above the second mixer, which is generally used for the enhancement of trace ingredients. At the same time, there is a liquid addition system on the mixer for the addition of oil; one is for the addition of water. In the second blending procedure, numerous materials need to be totally combined, as well as the coefficient of variation CV is less than 7%, which is the vital to ensuring item top quality.

For that reason, the mixer should choose a design with superb efficiency, such as double-shaft horizontal paddle mixing It has high blending harmony, high output and quick mixing rate. After additional crushing as well as second component blending, the product gets in the subsequent procedure-- development granulation procedure-- with fish feed extruder machine.
4. Extrusion process by fish feed extruder device.
In the extrusion procedure, the product in fact undergoes a cooking procedure under the conditions of high temperature, high moisture and also high pressure.
Throughout this fish feed extruder device procedure, the physical and chemical residential or commercial properties of the material transformed highly, as well as presently when the product was squeezed out from the die opening, the water in the feed was instantly converted from liquid to gaseous state and also sent out from the feed because the pressure suddenly dropped from high pressure to about 100kPa.
Consequently, the material is squeezed out by fish feed extruder machine to form the so-called extruded feed. Because this kind of feed not only has the advantages of basic tough pellet feed - excellent palatability, avoids automatic grading of items, is easy to deliver, helps digestion, reduces waste in the feeding procedure, etc, but also has special benefits:.
In the feed, the starch has a high degree of gelatinization by fish feed extruder maker, the healthy protein is extra absorbable, and the usage price of the pet feed is improved; it has superb floatability, which is very easy to observe the feeding situation of the fish, as well as can control the water air pollution to the maximum level. These are additionally the major reasons extruded feed is widely made use of.
There are several kinds of dryers can be made use of after fish feed extruder equipment. When the size of the pellets is less than 4mm, a shaking fluidized bed clothes dryer can be selected; when the diameter of the pellets is more than 4mm, a belt clothes dryer can be chosen, or a horizontal float clothes dryer can be straight picked.
Since this sort of clothes dryer can make the product in a semi-suspended state on the whole display surface area, it can not just ensure the drying out result, but also reduce the damages to the pellets. After the material is dried, it enters the exterior spraying system.
The outside spraying of the pellets is mainly to meet the fish's power requirements as well as decrease the loss of heat-sensitive compounds throughout processing. The nutrients that should not be added in the previous procedure can be supplemented by outside spraying, as well as at the same time, the palatability of the feed can be enhanced and the powder material can be reduced.
The optimal functioning temperature for this process is around 80 ℃. After the material travels through the outside spraying system, it can enter the counter-flow colder for cooling.
5. Completed product packaging.
The cooled down material is raised by the elevator and then squashed into the plane rotary screen for category. The grading screen made use of after fish feed extruder maker is normally a two-layer sieve, as well as the material on the reduced screen is the completed product, which can be directly entered into the completed item stockroom, and then evaluated and also packaged. The product on the upper sieve needs to be returned to the crusher for crushing. The product under the lower filter is normally finely smashed, which can be gone back to the batching bin as waste.
The fish feed extruder maker production process examined above is the standard setup of the existing aquatic extruded feed processing technology. Using this procedure, sinking feed, slow-moving sinking feed as well as floating feed can be created.
Although extruded fish feed extruder maker innovation has been identified by lots of producers as a brand-new kind of processing technology, it has not been extensively used due to the fact that its financial investment is a lot larger than that of hard pellet feed processing innovation.
Nevertheless, the fish feed extruder equipment blowing process is the future development pattern of the feed processing industry, especially in the application of aquatic animal feed as well as pet feed, and also will certainly change the traditional tough pellet feed processing technology.
