With the rapid growth of the aquaculture industry, conventional farming techniques have actually been far from fulfilling individuals's needs. The needs for aquaculture fish feed made by fish feed extruder maker are not just balanced nutrition, great stability of the feed in water, no pollution to water quality, etc, as well as a lot more rigorous requirements are advanced for the environmental quality of fish survival.
The feed produced by the aquaculture fish feed extruder equipment is hard pellets, as well as the other is the extruded feed pellet equipment, as well as the refined fish feed is soft pellets.
Today, Richi Machinery will certainly talk about the extruded feed fish feed extruder equipment. The production process typically adopts second squashing as well as second ingredient mixing, and afterwards travels through extrusion, drying out, outside spraying, cooling down, squashing as well as screening to finish the handling of aquatic extruded feed.

1. Basic material cleaning as well as primary grinding.
There are generally 2 forms of basic materials used in drifting fish feed factories: one is powder, which does not require to be coarsely grated. For this sort of resources, it can straight go into the cone-shaped cleaning screen to eliminate contaminations after going through the feeding pit as well as lift, and afterwards conduct magnetic separation, and also straight get in the batching container with the supplier or screw auger to join the very first batching;.
The material that requires to be coarsely shattered-- granular material. This type of product enters the cleansing equipment via the unloading pit and also the elevator to go into the cleaning devices for magnetic splitting up of pollutants, and after that gets in the to-be-pulverized bin.
For private basic materials, such as shrimp coverings, they can be directly taken into the silo to be crushed after magnetic splitting up without initial sieving.
Single rugged pulverization is the pretreatment procedure of ultrafine pulverization in marine feed processing. Its main function is to reduce the pellet dimension distinction and variant variety of products, improve the working problem of the ultrafine pulverizer, as well as improve the functioning performance and guarantee of the ultrafine pulverizer.
The product high quality is stable; at the same time, in order to enhance the working environment of employees and minimize cross-contamination, it is recommended to utilize an independent dirt elimination air net, that is, an independent dirt removal system for the feeding port.

2. The first batching and also blending.
The initial batching is mostly the prep work of public basic materials, that is, the prep work of larger materials in the formula. This fish feed extruder device procedure is mostly completed by electronic batching ranges.
However, in the very first batching process, special focus ought to be paid to the arching issue of the batching container, which is mainly triggered by the light bulk thickness and bad fluidity of the raw products of the aquatic feed, specifically the high-grade aquatic feed raw materials. For that reason, particular anti-arching actions should be considered the batching container, such as the use of eccentric discharge, vibration motor, etc.
The single-shaft horizontal bow mixer can be used for the first mixing, as well as the oil enhancement system must be taken into consideration on the mixer. The initial batching and mixing is additionally the pre-treatment process of ultra-fine pulverization.
This auxiliary devices of fish feed extruder machine is mainly to reduce the variation variety of product pellet dimension, enhance the working problem of the pulverizer, enhance the functioning effectiveness of the pulverizer, and guarantee the high quality of the product.

3. Second squashing and blending of additional components.
Due to the reduced food consumption, short digestion tract and also poor gastrointestinal capacity of water pets, aquatic feed needs very fine crushing pellet size to raise the surface of the feed, boost the get in touch with location between the digestion juice of marine pets and the feed, and enhance the capability of water animals to feed the feed.
At the same time, as a result of the low consumption of water animals, the blending harmony of the feed is required to be mirrored in a smaller range, which likewise requires the water feed to have a finer pellet dimension.
For example, the shrimp feed need to all travel through the 40-mesh analytical sieve, as well as the material on the 60-mesh sieve must be less than 5%, so the micro-grinding procedure should be adopted.
In the secondary pulverization procedure, the products mixed in the very first time are raised by the elevator and then enter the silo to be pulverized, and then get in the mini pulverizer. Micro-pulverizers are usually used in the processing of water feeds, and also vertical-axis micro-pulverizers are generally used, which are geared up with powerful wind separation equipment, and afterwards enter the rotating grading display for testing.
The purpose of configuring the rotary grading screen right here is mostly to remove the fine fluff formed by the rugged fibers in the feed throughout the pulverization process, since the presence of these great fluff is easy to stick to the die opening of the fish feed extruder machine till the die opening is blocked, creating Shut down for cleaning, so it should be gotten rid of.
The cleaned up products undergo secondary batching and also blending. Since the fineness of the products entering the second batching mixing bin is above 60 mesh as well as the density is small, special attention must be paid to the sensation of arching.

In order to avoid this sensation, on the one hand, the eccentric sub-expansion receptacle can be used, and on the other hand, all the material discharge devices that have gone through ultra-fine grinding utilize an impeller feeder, which not just has an arch splitting device, yet also can flexibly change the circulation price. size. Various basic materials go into the second mixer after additional batching.
There is an fabricated feeding port above the second mixer, which is mostly used for the addition of trace additives. At the same time, there is a liquid enhancement mechanism on the mixer for the addition of oil; one is for the enhancement of water. In the secondary mixing process, numerous products should be totally blended, and the coefficient of variant curriculum vitae is less than 7%, which is the crucial to making certain item high quality.
Consequently, the mixer should choose a model with superb performance, such as double-shaft horizontal paddle blending It has high blending uniformity, high result and also quick blending rate. After secondary crushing and also additional component mixing, the material goes into the subsequent process-- growth granulation procedure-- with fish feed extruder machine.
4. Extrusion procedure by fish feed extruder maker.
In the extrusion procedure, the material in fact goes through a cooking process under the problems of high temperature, high humidity as well as high pressure.
During this fish feed extruder machine procedure, the physical and also chemical buildings of the material transformed strongly, as well as presently when the material was squeezed out from the die hole, the water in the feed was promptly converted from fluid to aeriform state and sent out from the feed since the stress instantly went down from high pressure to concerning 100kPa.
Therefore, the material is extruded by fish feed extruder maker to create the so-called extruded feed. Due to the fact that this sort of feed not only has the advantages of general hard pellet feed - good palatability, stays clear of automated grading of items, is very easy to move, assists food digestion, reduces waste in the feeding process, etc, but also has distinct advantages:.
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 utilization rate of the pet feed is enhanced; it has superb floatability, which is simple to observe the feeding scenario of the fish, and also can control the water contamination to the optimum level. These are additionally the main reasons that extruded feed is commonly used.
There are numerous sort of clothes dryers can be utilized after fish feed extruder machine. When the diameter of the pellets is less than 4mm, a shaking fluidized bed clothes dryer can be chosen; when the size of the pellets is above 4mm, a belt clothes dryer can be picked, or a horizontal float dryer can be directly picked.
Since this type of dryer can make the product in a semi-suspended state on the entire display surface area, it can not only ensure the drying out impact, however additionally reduce the damages to the pellets. After the product is dried out, it gets in the outside spraying system.
The exterior splashing of the pellets is mostly to fulfill the fish's energy needs and minimize the loss of heat-sensitive substances during handling. The nutrients that need to not be included the previous process can be supplemented by external spraying, as well as at the same time, the palatability of the feed can be boosted as well as the powder material can be lowered.
The maximum working temperature level for this procedure is around 80 ℃. After the material travels through the exterior spraying system, it can get in the counter-flow cooler for air conditioning.

5. Completed item packaging.
The cooled material is lifted by the elevator and after that crushed right into the airplane rotary display for classification. The grading screen used after fish feed extruder maker is generally a two-layer sieve, and also the product on the reduced sieve is the completed item, which can be directly participated in the completed item storehouse, and then evaluated and packaged. The product on the upper screen requires to be gone back to the crusher for crushing. The material under the reduced sieve is typically carefully smashed, which can be returned to the batching container as waste.
The fish feed extruder equipment production process analyzed above is the conventional setup of the current aquatic extruded feed processing modern technology. Utilizing this procedure, sinking feed, slow-moving sinking feed and also floating feed can be generated.
Although extruded fish feed extruder device modern technology has actually been recognized by numerous suppliers as a new kind of handling technology, it has not been widely utilized due to the fact that its financial investment is a lot larger than that of tough pellet feed processing innovation.
Nonetheless, the fish feed extruder maker puffing procedure is the future advancement fad of the feed processing market, especially in the application of marine animal feed as well as pet feed, and also will absolutely replace the traditional difficult pellet feed processing technology.
