Today, Richi Machinery will speak about the extruded feed fish feed extruder equipment. The production procedure usually takes on additional squashing as well as second component mixing, and afterwards goes through extrusion, drying out, external spraying, cooling down, squashing as well as screening to finish the handling of water extruded feed.
1. Resources cleansing and also main grinding.
There are normally two forms of resources used in floating fish feed factories: one is powder, which does not require to be coarsely grated. For this type of resources, it can straight go into the conelike cleaning screen to get rid of contaminations after passing through the feeding pit and elevator, and afterwards perform magnetic splitting up, and directly get in the batching bin with the supplier or screw auger to join the initial batching;
The product that needs to be coarsely pulverized-- granular product. This sort of product enters the cleansing tools through the dumping pit and the lift to enter the cleaning equipment for magnetic splitting up of impurities, and after that goes into the to-be-pulverized container.

For private basic materials, such as shrimp coverings, they can be directly put into the silo to be crushed after magnetic splitting up without initial sieving.
One-time coarse pulverization is the pretreatment procedure of ultrafine pulverization in aquatic feed processing. Its major objective is to minimize the pellet size distinction and variant variety of products, boost the working condition of the ultrafine pulverizer, and also improve the working effectiveness and also warranty of the ultrafine pulverizer.
The product quality is steady; at the same time, in order to improve the working environment of employees and lower cross-contamination, it is suggested to utilize an independent dirt elimination air internet, that is, an independent dust removal system for the feeding port.

2. The initial batching as well as blending.
The very first batching is mostly the preparation of public raw materials, that is, the prep work of bigger products in the formula. This fish feed extruder maker process is mainly completed by digital batching scales.
Nonetheless, in the first batching process, unique attention ought to be paid to the arching trouble of the batching container, which is mainly brought on by the light mass density and also bad fluidity of the raw materials of the aquatic feed, particularly the high-grade marine feed raw materials. For that reason, particular anti-arching actions should be considered the batching bin, such as making use of eccentric discharge, resonance electric motor, etc.
The single-shaft straight bow mixer can be made use of for the initial mixing, as well as the oil enhancement system have to 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 auxiliary tools of fish feed extruder maker is mostly to decrease the variation series of product pellet dimension, enhance the working condition of the pulverizer, enhance the working effectiveness of the pulverizer, as well as make sure the top quality of the item.

3. Second crushing as well as mixing of additional components.
Due to the low food intake, brief gastrointestinal tract and inadequate digestive capability of aquatic animals, aquatic feed calls for extremely great crushing pellet size to boost the surface of the feed, raise the get in touch with location in between the gastrointestinal juice of marine pets as well as the feed, as well as improve the capability of aquatic animals to feed the feed.
At the same time, due to the low intake of marine pets, the blending harmony of the feed is called for to be shown in a smaller range, which likewise requires the water feed to have a finer pellet dimension.
As an example, the shrimp feed should all pass through the 40-mesh analytical sieve, and the web content on the 60-mesh filter ought to be less than 5%, so the micro-grinding process should be taken on.
In the second pulverization procedure, the products mixed in the first time are lifted by the lift and afterwards get in the silo to be shattered, and after that enter the mini pulverizer. Micro-pulverizers are usually utilized in the processing of water feeds, and also vertical-axis micro-pulverizers are typically made use of, which are equipped with powerful wind splitting up devices, and afterwards go into the rotating grading screen for testing.
The purpose of setting up the rotating grading display right here is primarily to remove the great fluff created by the rugged fibers in the feed during the pulverization process, since the existence of these great fluff is very easy to abide by the die hole of the fish feed extruder device up until the die hole is blocked, triggering Close down for cleansing, so it must be gotten rid of.
The cleaned up materials are subjected to secondary batching and also mixing. Considering that the fineness of the products getting in the additional batching mixing container is above 60 mesh and also the thickness is little, unique interest ought to be paid to the sensation of arching.
In order to prevent this phenomenon, 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 actually undertaken ultra-fine grinding make use of an impeller feeder, which not only has an arch breaking device, but likewise can flexibly adjust the circulation rate. size. Various resources go into the second mixer after second batching.
There is an fabricated feeding port above the secondary mixer, which is generally utilized for the addition of trace ingredients. At the same time, there is a fluid enhancement system on the mixer for the addition of oil; one is for the enhancement of water. In the second mixing procedure, numerous products have to be fully mixed, and also the coefficient of variation curriculum vitae is less than 7%, which is the key to ensuring item top quality.
As a result, the mixer needs to select a version with superb efficiency, such as double-shaft horizontal paddle mixing It has high mixing uniformity, high outcome and quick mixing speed. After secondary crushing and also secondary ingredient blending, the material enters the subsequent process-- development granulation procedure-- with fish feed extruder equipment.
4. Extrusion process by fish feed extruder machine.
In the extrusion process, the product really undertakes a cooking process under the conditions of high temperature, high moisture and high pressure.
During this fish feed extruder maker procedure, the physical and also chemical buildings of the product altered highly, and also right now when the product was extruded from the die opening, the water in the feed was promptly transformed from liquid to gaseous state and also released from the feed due to the fact that the pressure suddenly went down from high pressure to concerning 100kPa.
Thereby, the product is squeezed out by fish feed extruder maker to form the supposed extruded feed. Due to the fact that this type of feed not just has the advantages of general tough pellet feed - excellent palatability, prevents automated grading of products, is simple to transport, aids digestion, lowers waste in the feeding procedure, and so on, however additionally has distinct benefits:.
In the feed, the starch has a high level of gelatinization by fish feed extruder device, the healthy protein is extra absorbable, and also the use rate of the pet feed is improved; it has superb floatability, which is simple to observe the feeding scenario of the fish, and also can regulate the water air pollution to the optimum extent. These are additionally the major reasons that extruded feed is commonly utilized.
There are lots of type of dryers can be used after fish feed extruder device. 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 dryer can be chosen, or a horizontal float dryer can be directly chosen.
Since this kind of clothes dryer can make the material in a semi-suspended state on the whole display surface, it can not only make sure the drying out impact, however additionally minimize the damage to the pellets. After the product is dried out, it enters the external spraying system.
The external spraying of the pellets is primarily to satisfy the fish's energy requirements as well as minimize the loss of heat-sensitive substances during handling. The nutrients that must not be included the previous process can be supplemented by outside spraying, and also at the same time, the palatability of the feed can be enhanced and also the powder material can be decreased.
The maximum working temperature for this procedure is around 80 ℃. After the material travels through the exterior spraying system, it can go into the counter-flow cooler for cooling.
5. Finished item packaging.
The cooled product is raised by the elevator and afterwards squashed into the airplane rotating display for classification. The grading filter utilized after fish feed extruder maker is generally a two-layer screen, as well as the material on the lower sieve is the ended up product, which can be directly entered into the completed product storage facility, and afterwards weighed and packaged. The product on the top screen needs to be gone back to the crusher for crushing. The product under the lower screen is generally carefully crushed, which can be returned to the batching container as waste.
The fish feed extruder machine manufacturing process evaluated above is the traditional configuration of the present marine extruded feed processing modern technology. Using this process, sinking feed, sluggish sinking feed as well as drifting feed can be created.
Although extruded fish feed extruder machine technology has actually been acknowledged by many suppliers as a brand-new kind of handling modern technology, it has actually not been extensively used because its financial investment is a lot larger than that of hard pellet feed processing innovation.
Nevertheless, the fish feed extruder equipment blowing procedure is the future development trend of the feed handling industry, especially in the application of marine pet feed as well as pet feed, and will certainly replace the traditional hard pellet feed handling innovation.
