With the rapid development of the aquaculture sector, conventional farming approaches have been far from fulfilling individuals's needs. The needs for aquaculture fish feed made by fish feed extruder equipment are not only balanced nourishment, good security of the feed in water, no pollution to water high quality, and so on, and more stringent requirements are put forward for the ecological quality of fish survival.
The feed produced by the aquaculture fish feed extruder device is difficult pellets, and the various other is the extruded feed pellet maker, and also the refined fish feed is soft pellets.
Today, Richi Machinery will talk about the extruded feed fish feed extruder maker. The manufacturing process generally takes on second squashing and secondary active ingredient mixing, and afterwards goes through extrusion, drying out, exterior splashing, cooling, squashing as well as evaluating to finish the handling of marine extruded feed.
1. Basic material cleansing and main grinding.
There are usually two types of raw materials utilized in floating fish feed factories: one is powder, which does not require to be coarsely grated. For this kind of basic material, it can directly get in the conelike cleaning screen to remove pollutants after travelling through the feeding pit and also elevator, and then perform magnetic separation, as well as directly get in the batching container via the representative or screw auger to take part in the first batching;.
The material that requires to be coarsely crushed-- granular product. This type of product gets in the cleaning tools with the dumping pit and the elevator to go into the cleansing equipment for magnetic separation of pollutants, and then goes into the to-be-pulverized container.
For private resources, such as shrimp coverings, they can be directly taken into the silo to be crushed after magnetic splitting up without first sieving.
One-time crude pulverization is the pretreatment procedure of ultrafine pulverization in water feed handling. Its primary objective is to minimize the pellet size difference and also variant series of products, boost the functioning problem of the ultrafine pulverizer, and also improve the working performance and also guarantee of the ultrafine pulverizer.
The product quality is secure; at the same time, in order to enhance the workplace of workers and also minimize cross-contamination, it is suggested to make use of an independent dust removal air net, that is, an independent dirt removal system for the feeding port.
2. The first batching and blending.
The very first batching is generally the prep work of public basic materials, that is, the preparation of bigger materials in the formula. This fish feed extruder equipment procedure is mostly completed by electronic batching scales.
Nonetheless, in the very first batching procedure, special attention should be paid to the arching problem of the batching container, which is generally brought on by the light mass thickness and bad fluidness of the raw products of the water feed, specifically the state-of-the-art water feed raw materials. For that reason, certain anti-arching actions must be taken for the batching container, such as using eccentric discharge, vibration electric motor, etc.
The single-shaft straight ribbon mixer can be used for the initial mixing, and the oil enhancement system need to be taken into consideration on the mixer. The very first batching as well as blending is likewise the pre-treatment process of ultra-fine pulverization.
This complementary equipment of fish feed extruder maker is mainly to lower the variant range of material pellet size, boost the functioning problem of the pulverizer, enhance the working performance of the pulverizer, as well as make sure the quality of the item.
3. Second crushing and mixing of second active ingredients.
Due to the low food intake, brief gastrointestinal tract and poor gastrointestinal ability of water animals, water feed requires very great squashing pellet size to raise the surface area of the feed, boost the call area in between the digestive juice of water animals and the feed, and improve the capacity of marine pets to feed the feed.
At the same time, due to the low intake of water pets, the mixing uniformity of the feed is called for to be mirrored in a smaller sized array, which also needs the water feed to have a better pellet size.
For example, the shrimp feed should all pass through the 40-mesh logical sieve, as well as the content on the 60-mesh screen must be less than 5%, so the micro-grinding procedure should be embraced.
In the additional pulverization procedure, the materials mixed in the very first time are raised by the lift and afterwards go into the silo to be pulverized, and after that go into the micro pulverizer. Micro-pulverizers are generally made use of in the handling of marine feeds, and vertical-axis micro-pulverizers are typically used, which are geared up with powerful wind splitting up tools, and after that get in the rotary grading display for testing.
The purpose of configuring the rotary grading screen right here is generally to get rid of the great fluff developed by the coarse fibers in the feed throughout the pulverization procedure, because the presence of these fine fluff is easy to comply with the die hole of the fish feed extruder equipment up until the die hole is obstructed, creating Close down for cleaning, so it needs to be removed.
The cleaned materials go through secondary batching as well as blending. Since the excellence of the products entering the secondary batching mixing container is above 60 mesh as well as the density is tiny, unique attention should be paid to the phenomenon of arching.
In order to stop this phenomenon, on the one hand, the eccentric sub-expansion receptacle can be used, as well as on the other hand, all the material discharge devices that have actually undergone ultra-fine grinding make use of an impeller feeder, which not just has an arch breaking mechanism, however also can flexibly adjust the flow rate. size. Numerous basic materials enter the secondary mixer after second batching.
There is an synthetic feeding port over the additional mixer, which is mostly utilized for the addition of trace additives. At the same time, there is a liquid addition mechanism on the mixer for the enhancement of grease; one is for the enhancement of water. In the second blending process, different materials should be completely mixed, as well as the coefficient of variation curriculum vitae is less than 7%, which is the key to ensuring item quality.
As a result, the mixer has to pick a model with exceptional performance, such as double-shaft horizontal paddle blending It has high mixing uniformity, high result and fast mixing rate. After secondary crushing and second ingredient blending, the product enters the subsequent process-- expansion granulation process-- with fish feed extruder maker.
4. Extrusion process by fish feed extruder machine.
In the extrusion procedure, the material actually undergoes a cooking process under the conditions of high temperature, high humidity and high pressure.
During this fish feed extruder equipment process, the physical as well as chemical residential or commercial properties of the product transformed highly, as well as right now when the material was extruded from the die opening, the water in the feed was right away transformed from fluid to gaseous state and released from the feed due to the fact that the pressure unexpectedly dropped from high pressure to about 100kPa.
Consequently, the material is squeezed out by fish feed extruder equipment to form the supposed extruded feed. Because this kind of feed not just has the advantages of basic tough pellet feed - great palatability, avoids automatic grading of items, is very easy to transport, aids food digestion, lowers waste in the feeding process, and so on, but also has one-of-a-kind advantages:.
In the feed, the starch has a high degree of gelatinization by fish feed extruder machine, the protein is more absorbable, and also the application price of the pet feed is enhanced; it has excellent floatability, which is easy to observe the feeding scenario of the fish, as well as can regulate the water air pollution to the optimum extent. These are also the main reasons that extruded feed is widely used.
There are several type of clothes dryers can be used after fish feed extruder device. When the size of the pellets is less than 4mm, a vibrating fluidized bed clothes dryer can be chosen; when the diameter of the pellets is above 4mm, a belt clothes dryer can be selected, or a straight float dryer can be directly chosen.
Since this kind of dryer can make the product in a semi-suspended state on the entire screen surface, it can not only make sure the drying out result, but additionally reduce the damage to the pellets. After the product is dried, it enters the external spraying system.
The outside splashing of the pellets is mainly to fulfill the fish's power requirements as well as lower the loss of heat-sensitive materials during handling. The nutrients that must not be included the previous procedure can be supplemented by external splashing, and at the same time, the palatability of the feed can be improved and the powder content can be minimized.
The optimum functioning temperature level for this procedure is around 80 ℃. After the product goes through the external splashing system, it can enter the counter-flow colder for air conditioning.
5. Completed product packaging.
The cooled material is raised by the lift and after that squashed into the airplane rotary screen for category. The rating filter utilized after fish feed extruder device is usually a two-layer screen, as well as the product on the reduced filter is the completed product, which can be directly entered into the finished item storage facility, and after that evaluated and packaged. The product on the upper sieve needs to be returned to the crusher for crushing. The product under the reduced sieve is usually finely crushed, which can be gone back to the batching container as waste.
The fish feed extruder machine manufacturing procedure evaluated above is the standard arrangement of the current aquatic extruded feed processing technology. Utilizing this procedure, sinking feed, sluggish sinking feed and also drifting feed can be produced.
Although extruded fish feed extruder device innovation has actually been identified by numerous producers as a brand-new type of processing technology, it has actually not been commonly used due to the fact that its financial investment is much larger than that of tough pellet feed handling modern technology.
However, the fish feed extruder equipment puffing procedure is the future growth pattern of the feed handling market, especially in the application of water pet feed and also pet dog feed, and also will absolutely replace the conventional hard pellet feed handling modern technology.
I really hope the above related web content about fish feed extruder maker is practical to you. To find out more concerning floating fish feed granulator equipment, you rate to consult the team of Richi Equipment, we will certainly serve you wholeheartedly!
