Manufacturing process of fish feed extruder device
With the quick growth of the aquaculture market, typical farming methods have been far from fulfilling people's requirements. The needs for aquaculture fish feed made by fish feed extruder device are not only balanced nutrition, great stability of the feed in water, no contamination to water high quality, and so on, and also much more stringent demands are advanced for the environmental high quality of fish survival.
The feed generated by the aquaculture fish feed extruder machine is tough pellets, and the other is the extruded feed pellet equipment, as well as the refined fish feed is soft pellets.
Today, Richi Machinery will certainly discuss the extruded feed fish feed extruder equipment. The manufacturing process usually takes on additional crushing as well as additional ingredient mixing, and after that goes through extrusion, drying, exterior splashing, cooling down, squashing and also evaluating to finish the processing of marine extruded feed.

1. Basic material cleaning and also key grinding.
There are generally 2 forms of resources utilized in drifting fish feed manufacturing facilities: one is powder, which does not require to be coarsely grated. For this type of raw material, it can directly go into the conelike cleansing display to remove contaminations after travelling through the feeding pit and also lift, and after that conduct magnetic separation, and also straight get in the batching container via the supplier or screw auger to take part in the initial batching;.
The product that requires to be coarsely pulverized-- granular product. This sort of material gets in the cleaning equipment with the discharging pit and also the elevator to enter the cleaning tools for magnetic separation of contaminations, and afterwards goes into the to-be-pulverized bin.
For specific resources, such as shrimp shells, they can be straight taken into the silo to be crushed after magnetic separation without first sieving.
One-time rugged pulverization is the pretreatment procedure of ultrafine pulverization in water feed processing. Its primary purpose is to lower the pellet dimension difference as well as variation series of products, boost the working problem of the ultrafine pulverizer, as well as improve the working effectiveness and also warranty of the ultrafine pulverizer.
The product high quality is secure; at the same time, in order to improve the working environment of employees and lower cross-contamination, it is advised to utilize an independent dirt elimination air web, that is, an independent dust removal system for the feeding port.

2. The first batching and mixing.
The first batching is mostly the prep work of public resources, that is, the prep work of larger products in the formula. This fish feed extruder maker procedure is mostly finished by electronic batching scales.
However, in the very first batching process, special interest must be paid to the arching issue of the batching container, which is mainly caused by the light mass thickness as well as poor fluidness of the raw products of the marine feed, particularly the top-quality marine feed basic materials. As a result, specific anti-arching procedures ought to be considered the batching bin, such as making use of eccentric discharge, vibration electric motor, etc.
The single-shaft horizontal ribbon mixer can be utilized for the first mixing, as well as the oil addition system should be thought about on the mixer. The initial batching as well as blending is likewise the pre-treatment process of ultra-fine pulverization.
This complementary devices of fish feed extruder machine is mainly to minimize the variant series of product pellet dimension, enhance the functioning condition of the pulverizer, improve the functioning performance of the pulverizer, as well as make sure the high quality of the product.

3. Second crushing and also blending of additional active ingredients.
Because of the low food consumption, brief digestive system system and bad digestive system capacity of water pets, aquatic feed requires very fine squashing pellet dimension to increase the surface of the feed, increase the get in touch with area between the gastrointestinal juice of aquatic pets as well as the feed, and improve the ability of water pets to feed the feed.
At the same time, due to the low consumption of marine pets, the mixing harmony of the feed is needed to be reflected in a smaller array, which likewise needs the water feed to have a finer pellet size.
For example, the shrimp feed should all travel through the 40-mesh analytical screen, and the content on the 60-mesh filter should be less than 5%, so the micro-grinding procedure should be taken on.
In the additional pulverization procedure, the products mixed in the first time are lifted by the elevator and afterwards enter the silo to be shattered, and afterwards enter the mini pulverizer. Micro-pulverizers are normally used in the processing of water feeds, and also vertical-axis micro-pulverizers are usually utilized, which are equipped with powerful wind splitting up tools, and afterwards get in the rotating grading display for screening.
The function of configuring the rotating grading screen here is mainly to eliminate the great fluff created by the crude fibers in the feed throughout the pulverization procedure, since the existence of these great fluff is easy to follow the die hole of the fish feed extruder machine till the die opening is obstructed, creating Shut down for cleaning, so it has to be gotten rid of.
The cleansed materials go through second batching and mixing. Given that the fineness of the products going into the second batching blending bin is above 60 mesh as well as the thickness is small, special focus ought to be paid to the phenomenon of arching.

In order to avoid this sensation, on the one hand, the eccentric sub-expansion receptacle can be utilized, and also on the other hand, all the material discharge makers that have undergone ultra-fine grinding utilize an impeller feeder, which not only has an arch breaking mechanism, but additionally can flexibly change the circulation price. size. Numerous basic materials enter the additional mixer after secondary batching.
There is an fabricated feeding port over the additional mixer, which is mainly utilized for the enhancement of trace additives. At the same time, there is a liquid enhancement system on the mixer for the addition of oil; one is for the addition of water. In the additional mixing procedure, numerous products should be fully mixed, and also the coefficient of variant curriculum vitae is less than 7%, which is the essential to ensuring product quality.
For that reason, the mixer must select a version with outstanding performance, such as double-shaft horizontal paddle mixing It has high blending harmony, high output as well as rapid blending rate. After secondary crushing and second component blending, the product gets in the subsequent procedure-- expansion granulation process-- with fish feed extruder maker.
4. Extrusion procedure by fish feed extruder maker.
In the extrusion procedure, the product in fact undergoes a cooking process under the conditions of heat, high moisture as well as high pressure.
During this fish feed extruder equipment process, the physical as well as chemical properties of the material altered highly, and also presently when the material was squeezed out from the die opening, the water in the feed was immediately transformed from liquid to aeriform state and discharged from the feed since the pressure instantly dropped from high pressure to about 100kPa.
Consequently, the material is squeezed out by fish feed extruder device to develop the so-called extruded feed. Because this kind of feed not only has the advantages of general tough pellet feed - great palatability, avoids automatic grading of products, is very easy to move, assists food digestion, lowers waste in the feeding process, and so on, but also has special benefits:.
In the feed, the starch has a high level of gelatinization by fish feed extruder device, the healthy protein is extra digestible, and also the application rate of the pet feed is enhanced; it has superb floatability, which is simple to observe the feeding situation of the fish, and can regulate the water contamination to the optimum extent. These are likewise the major reasons why extruded feed is widely used.
There are several type of dryers can be made use of after fish feed extruder equipment. 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 higher than 4mm, a belt dryer can be chosen, or a horizontal float dryer can be directly selected.
Because this type of clothes dryer can make the material in a semi-suspended state on the whole display surface area, it can not just make sure the drying impact, however also minimize the damages to the pellets. After the product is dried, it goes into the external spraying system.
The outside splashing of the pellets is generally to fulfill the fish's power needs and lower the loss of heat-sensitive substances during handling. The nutrients that need to not be included the previous procedure can be supplemented by outside splashing, and also at the same time, the palatability of the feed can be enhanced as well as the powder material can be reduced.
The maximum functioning temperature for this procedure is around 80 ℃. After the material travels through the outside spraying system, it can enter the counter-flow colder for cooling.

5. Finished product packaging.
The cooled product is lifted by the lift and after that crushed into the plane rotary display for classification. The rating filter used after fish feed extruder equipment is generally a two-layer filter, and the material on the reduced screen is the finished item, which can be directly participated in the completed product storage facility, and afterwards evaluated as well as packaged. The product on the upper screen requires to be returned to the crusher for crushing. The material under the reduced screen is typically carefully crushed, which can be gone back to the batching bin as waste.
The fish feed extruder device production process analyzed above is the traditional arrangement of the current marine extruded feed processing technology. Utilizing this procedure, sinking feed, slow sinking feed and also floating feed can be generated.
Although extruded fish feed extruder equipment innovation has actually been identified by numerous producers as a new sort of processing technology, it has not been commonly utilized since its investment is a lot larger than that of difficult pellet feed handling innovation.
However, the fish feed extruder equipment puffing procedure is the future advancement fad of the feed handling industry, particularly in the application of marine animal feed as well as pet dog feed, and also will definitely change the traditional tough pellet feed processing modern technology.
