Today, Richi Equipment will certainly talk about the extruded feed fish feed extruder equipment. The production process normally takes on second squashing and additional ingredient blending, and after that goes through extrusion, drying out, outside spraying, cooling, crushing and evaluating to finish the handling of water extruded feed.
1. Resources cleansing and primary grinding.
There are usually 2 forms of raw materials made use of in floating fish feed manufacturing facilities: one is powder, which does not need to be coarsely pulverized. For this type of resources, it can directly go into the cone-shaped cleansing screen to remove contaminations after going through the feeding pit and also elevator, and afterwards conduct magnetic separation, and straight go into the batching bin through the distributor or screw auger to participate in the initial batching;.
The product that needs to be coarsely pulverized-- granular product. This sort of product gets in the cleansing equipment via the dumping pit and the elevator to go into the cleansing tools for magnetic splitting up of pollutants, and afterwards enters the to-be-pulverized container.

For specific resources, such as shrimp shells, they can be straight taken into the silo to be crushed after magnetic splitting up without preliminary sieving.
Single coarse pulverization is the pretreatment procedure of ultrafine pulverization in aquatic feed processing. Its main function is to minimize the pellet dimension distinction and variant range of materials, enhance the working condition of the ultrafine pulverizer, as well as improve the working efficiency as well as assurance of the ultrafine pulverizer.
The product high quality is stable; at the same time, in order to enhance the workplace of employees as well as lower cross-contamination, it is advised to utilize an independent dirt elimination air net, that is, an independent dirt removal system for the feeding port.
2. The first batching and blending.
The first batching is primarily the prep work of public resources, that is, the prep work of larger materials in the formula. This fish feed extruder machine procedure is mostly completed by electronic batching ranges.
However, in the first batching procedure, unique attention must be paid to the arching trouble of the batching bin, which is mostly triggered by the light mass thickness as well as poor fluidness of the raw products of the aquatic feed, specifically the state-of-the-art water feed raw materials. As a result, certain anti-arching steps should be considered the batching bin, such as making use of eccentric discharge, resonance electric motor, etc.

The single-shaft straight ribbon mixer can be utilized for the very first blending, and the oil enhancement system must be taken into consideration on the mixer. The initial batching as well as mixing is also the pre-treatment procedure of ultra-fine pulverization.
This complementary devices of fish feed extruder device is mostly to reduce the variation series of material pellet dimension, enhance the functioning problem of the pulverizer, boost the working effectiveness of the pulverizer, as well as make certain the high quality of the product.
3. Additional squashing as well as blending of additional components.
Because of the low food consumption, brief gastrointestinal system and also inadequate digestive ability of aquatic animals, water feed needs extremely fine squashing pellet size to raise the surface area of the feed, increase the contact location in between the gastrointestinal juice of water pets and the feed, and also boost the capacity of water pets to feed the feed.
At the same time, due to the reduced consumption of aquatic pets, the mixing uniformity of the feed is needed to be reflected in a smaller sized array, which additionally requires the water feed to have a finer pellet dimension.

For instance, the shrimp feed should all go through the 40-mesh logical sieve, and the material on the 60-mesh screen must be less than 5%, so the micro-grinding procedure must be embraced.
In the additional pulverization process, the products mixed in the first time are raised by the lift and then go into the silo to be pulverized, and after that enter the micro pulverizer. Micro-pulverizers are generally utilized in the handling of water feeds, and also vertical-axis micro-pulverizers are usually utilized, which are outfitted with effective wind separation tools, and after that get in the rotating grading screen for screening.
The function of setting up the rotary grading display right here is generally to remove the fine fluff developed by the crude fibers in the feed during the pulverization procedure, since the presence of these fine fluff is simple to comply with the die opening of the fish feed extruder equipment until the die hole is obstructed, triggering Close down for cleaning, so it must be removed.
The cleaned up materials go through second batching as well as mixing. Since the excellence of the products getting in the additional batching blending container is above 60 mesh and also the thickness is little, unique interest should be paid to the sensation of arching.

In order to stop this sensation, on the one hand, the eccentric sub-expansion receptacle can be made use of, and on the other hand, all the product discharge equipments that have gone through ultra-fine grinding make use of an impeller feeder, which not only has an arch splitting mechanism, however additionally can flexibly readjust the circulation rate. dimension. Different basic materials get in the secondary mixer after secondary batching.
There is an artificial feeding port over the additional mixer, which is primarily utilized for the enhancement of trace additives. At the same time, there is a fluid enhancement mechanism on the mixer for the addition of oil; one is for the enhancement of water. In the additional blending procedure, numerous products have to be fully blended, and also the coefficient of variation curriculum vitae is less than 7%, which is the essential to ensuring product high quality.
For that reason, the mixer has to pick a model with exceptional performance, such as double-shaft horizontal paddle blending It has high blending uniformity, high outcome and also quick blending speed. After second squashing as well as secondary active ingredient blending, the product goes into the succeeding procedure-- development granulation procedure-- with fish feed extruder equipment.
4. Extrusion process by fish feed extruder machine.
In the extrusion procedure, the material in fact goes through a cooking procedure under the conditions of heat, high humidity and high pressure.
Throughout this fish feed extruder equipment process, the physical and also chemical residential or commercial properties of the material transformed strongly, as well as presently when the product was squeezed out from the die hole, the water in the feed was immediately converted from fluid to gaseous state and emitted from the feed because the stress unexpectedly went down from high pressure to regarding 100kPa.
Thus, the product is squeezed out by fish feed extruder machine to create the so-called extruded feed. Because this kind of feed not just has the advantages of basic difficult pellet feed - excellent palatability, avoids automatic grading of items, is simple to move, aids digestion, minimizes waste in the feeding process, etc, but additionally has one-of-a-kind advantages:.
In the feed, the starch has a high degree of gelatinization by fish feed extruder equipment, the protein is a lot more digestible, as well as the utilization price of the animal feed is enhanced; it has superb floatability, which is simple to observe the feeding scenario of the fish, and can control the water pollution to the maximum extent. These are additionally the main reasons that extruded feed is commonly used.
There are numerous type of dryers can be utilized after fish feed extruder maker. When the size of the pellets is less than 4mm, a vibrating fluidized bed dryer can be chosen; when the diameter of the pellets is greater than 4mm, a belt clothes dryer can be selected, or a horizontal float clothes dryer can be directly chosen.
Since this sort of clothes dryer can make the material in a semi-suspended state on the entire screen surface, it can not only ensure the drying out effect, but likewise reduce the damages to the pellets. After the material is dried, it gets in the exterior splashing system.
The exterior splashing of the pellets is mainly to satisfy the fish's power requirements and decrease the loss of heat-sensitive compounds throughout processing. The nutrients that must not be added in the previous process can be supplemented by exterior splashing, and also at the same time, the palatability of the feed can be boosted and also the powder content can be reduced.
The optimal functioning temperature level for this procedure is around 80 ℃. After the material passes through the exterior splashing system, it can enter the counter-flow cooler for cooling.
5. Finished item packaging.
The cooled product is lifted by the elevator and then crushed into the airplane rotating screen for category. The rating filter made use of after fish feed extruder device is usually a two-layer filter, and the product on the reduced sieve is the finished item, which can be straight participated in the completed product storage facility, and after that evaluated as well as packaged. The material on the upper screen needs to be returned to the crusher for squashing. The product under the lower sieve is typically carefully crushed, which can be returned to the batching container as waste.
The fish feed extruder machine manufacturing process examined above is the standard arrangement of the existing aquatic extruded feed handling technology. Utilizing this process, sinking feed, slow sinking feed and also floating feed can be generated.
Although extruded fish feed extruder machine modern technology has been acknowledged by several manufacturers as a brand-new sort of handling modern technology, it has actually not been extensively used due to the fact that its investment is much larger than that of tough pellet feed processing modern technology.
Nevertheless, the fish feed extruder maker blowing procedure is the future advancement trend of the feed handling industry, particularly in the application of marine pet feed and pet dog feed, and will certainly change the typical difficult pellet feed processing technology.
