Today, Richi Equipment will certainly speak about the extruded feed fish feed extruder machine. The manufacturing process usually takes on additional squashing as well as second active ingredient blending, and afterwards passes through extrusion, drying out, outside splashing, cooling down, squashing and also screening to finish the processing of aquatic extruded feed.
- Basic material cleansing and key grinding.
There are generally 2 types of basic materials used in floating fish feed manufacturing facilities: one is powder, which does not require to be coarsely pulverized. For this sort of raw material, it can directly enter the conical cleansing display to eliminate contaminations after travelling through the feeding pit and also lift, and afterwards carry out magnetic splitting up, as well as straight get in the batching container via the representative or screw auger to take part in the initial batching;.
The product that requires to be coarsely shattered– granular material. This type of material gets in the cleaning devices via the discharging pit and also the elevator to enter the cleansing equipment for magnetic splitting up of contaminations, and after that enters the to-be-pulverized bin.
For specific basic materials, such as shrimp shells, they can be straight taken into the silo to be squashed after magnetic splitting up without initial sieving.

One-time rugged pulverization is the pretreatment process of ultrafine pulverization in aquatic feed handling. Its main function is to decrease the pellet dimension distinction and also variation series of materials, boost the working problem of the ultrafine pulverizer, as well as boost the functioning performance as well as warranty of the ultrafine pulverizer.
The product high quality is stable; at the same time, in order to boost the workplace of employees and also reduce cross-contamination, it is advised to utilize an independent dirt removal air web, that is, an independent dust elimination system for the feeding port.
- The very first batching as well as blending.
The first batching is mainly the prep work of public raw materials, that is, the prep work of bigger products in the formula. This fish feed extruder machine process is mainly finished by digital batching ranges.
Nonetheless, in the initial batching process, special interest ought to be paid to the arching issue of the batching container, which is generally triggered by the light mass density and also inadequate fluidity of the raw materials of the aquatic feed, particularly the high-grade aquatic feed raw materials. For that reason, particular anti-arching actions must be considered the batching container, such as using eccentric discharge, vibration motor, etc.

The single-shaft horizontal bow mixer can be utilized for the first mixing, and also the oil addition system have to be thought about on the mixer. The very first batching and also blending is additionally the pre-treatment process of ultra-fine pulverization.
This supporting equipment of fish feed extruder equipment is primarily to lower the variant range of product pellet size, improve the working problem of the pulverizer, enhance the functioning performance of the pulverizer, and make sure the quality of the item.
- Secondary crushing and also mixing of second active ingredients.
Due to the reduced food intake, short digestive tract and inadequate digestion capacity of water animals, water feed requires very fine squashing pellet size to raise the surface of the feed, increase the call area in between the digestion juice of marine animals and also the feed, and enhance the capability of water animals to feed the feed.
At the same time, as a result of the reduced intake of marine pets, the mixing harmony of the feed is called for to be reflected in a smaller range, which also requires the aquatic feed to have a finer pellet dimension.
For example, the shrimp feed need to all travel through the 40-mesh analytical filter, and the web content on the 60-mesh screen ought to be less than 5%, so the micro-grinding process must be adopted.

In the additional pulverization process, the materials mixed in the first time are lifted by the lift and then enter the silo to be crushed, and afterwards get in the micro pulverizer. Micro-pulverizers are generally used in the handling of water feeds, as well as vertical-axis micro-pulverizers are normally used, which are furnished with effective wind separation tools, and afterwards go into the rotary grading screen for testing.
The objective of setting up the rotating grading display right here is mainly to get rid of the fine fluff formed by the coarse fibers in the feed during the pulverization procedure, since the presence of these great fluff is simple to adhere to the die hole of the fish feed extruder maker until the die opening is obstructed, causing Shut down for cleansing, so it must be eliminated.
The cleaned up materials are subjected to second batching as well as blending. Given that the excellence of the materials getting in the second batching mixing bin is above 60 mesh and also the density is small, special focus needs to be paid to the phenomenon of arching.
In order to stop this sensation, on the one hand, the eccentric sub-expansion receptacle can be made use of, and also on the other hand, all the material discharge machines that have undertaken ultra-fine grinding make use of an impeller feeder, which not only has an arch splitting system, but likewise can flexibly change the circulation rate. size. Numerous raw materials enter the second mixer after additional batching.
There is an artificial feeding port over the secondary mixer, which is mainly made use of for the addition of trace ingredients. At the same time, there is a liquid addition mechanism on the mixer for the addition of grease; one is for the enhancement of water. In the secondary mixing procedure, various materials should be fully combined, and also the coefficient of variation CV is less than 7%, which is the essential to ensuring product high quality.
Therefore, the mixer needs to pick a version with exceptional performance, such as double-shaft horizontal paddle mixing It has high mixing uniformity, high output and fast mixing rate. After additional crushing as well as additional component blending, the product goes into the succeeding process– expansion granulation procedure– with fish feed extruder device.
- Extrusion process by fish feed extruder device.
In the extrusion process, the material actually undergoes a cooking procedure under the conditions of heat, high humidity as well as high pressure.
During this fish feed extruder device procedure, the physical and chemical properties of the material altered strongly, and also currently when the material was squeezed out from the die opening, the water in the feed was promptly converted from fluid to gaseous state and also emitted from the feed because the stress unexpectedly went down from high pressure to about 100kPa.
Thereby, the product is squeezed out by fish feed extruder device to develop the so-called extruded feed. Due to the fact that this sort of feed not just has the advantages of basic difficult pellet feed – great palatability, stays clear of automatic grading of products, is easy to carry, helps food digestion, reduces waste in the feeding procedure, and so on, yet also has distinct advantages:.
In the feed, the starch has a high level of gelatinization by fish feed extruder device, the healthy protein is more digestible, and the use price of the pet feed is improved; it has excellent floatability, which is very easy to observe the feeding circumstance of the fish, and can regulate the water contamination to the maximum extent. These are likewise the major reasons that extruded feed is commonly used.
There are several kinds of clothes dryers can be used after fish feed extruder maker. When the diameter of the pellets is less than 4mm, a shaking fluidized bed dryer can be selected; when the size of the pellets is greater than 4mm, a belt clothes dryer can be chosen, or a horizontal float dryer can be directly selected.
Since this type of dryer can make the material in a semi-suspended state on the entire screen surface area, it can not just ensure the drying effect, but also lessen the damage to the pellets. After the product is dried, it gets in the exterior spraying system.
The external spraying of the pellets is mostly to fulfill the fish’s power demands as well as reduce the loss of heat-sensitive materials during handling. The nutrients that need to not be included the previous procedure can be supplemented by outside spraying, and at the same time, the palatability of the feed can be enhanced and the powder material can be lowered.
The optimum working temperature for this process is around 80 ℃. After the product passes through the exterior splashing system, it can get in the counter-flow cooler for air conditioning.

5.Ended up product packaging.
The cooled product is lifted by the lift and after that crushed right into the airplane rotary display for category. The rating filter utilized after fish feed extruder device is generally a two-layer sieve, and the product on the lower sieve is the finished product, which can be straight participated in the ended up item storage facility, and then weighed as well as packaged. The material on the top filter needs to be returned to the crusher for squashing. The product under the reduced filter is usually finely smashed, which can be returned to the batching container as waste.
The fish feed extruder maker manufacturing procedure assessed above is the standard configuration of the current water extruded feed handling technology. Using this process, sinking feed, slow-moving sinking feed as well as floating feed can be generated.
Although extruded fish feed extruder device technology has actually been recognized by several producers as a brand-new kind of handling technology, it has actually not been extensively used since its investment is much larger than that of difficult pellet feed handling innovation.
However, the fish feed extruder equipment blowing procedure is the future development pattern of the feed processing sector, specifically in the application of water pet feed and family pet feed, as well as will absolutely change the standard tough pellet feed handling innovation.
