With the quick development of the aquaculture market, traditional farming methods have been much from meeting people's requirements. The needs for aquaculture fish feed made by fish feed extruder equipment are not only well balanced nourishment, excellent stability of the feed in water, no contamination to water high quality, etc, and also a lot more stringent needs are advanced for the ecological quality of fish survival.
The feed generated by the aquaculture fish feed extruder maker is hard pellets, as well as the other is the extruded feed pellet device, and the refined fish feed is soft pellets.
Today, Richi Equipment will certainly talk about the extruded feed fish feed extruder equipment. The production process generally adopts second squashing and secondary active ingredient blending, and then passes through extrusion, drying out, external splashing, cooling, squashing and also evaluating to finish the processing of aquatic extruded feed.

1. Raw material cleansing as well as key grinding.
There are generally 2 types of raw materials made use of in floating fish feed manufacturing facilities: one is powder, which does not need to be coarsely grated. For this type of basic material, it can straight enter the conelike cleaning display to eliminate pollutants after going through the feeding pit and elevator, and then carry out magnetic splitting up, as well as directly go into the batching container through the supplier or screw auger to take part in the very first batching;.
The product that requires to be coarsely crushed-- granular material. This sort of product goes into the cleansing equipment with the dumping pit and also the lift to enter the cleansing equipment for magnetic splitting up of pollutants, and then enters the to-be-pulverized bin.
For specific raw materials, such as shrimp coverings, they can be directly put into the silo to be crushed after magnetic separation without first sieving.
Single crude pulverization is the pretreatment process of ultrafine pulverization in aquatic feed handling. Its main objective is to decrease the pellet size difference and variation range of materials, boost the functioning condition of the ultrafine pulverizer, and also improve the working performance as well as guarantee of the ultrafine pulverizer.
The item high quality is steady; at the same time, in order to boost the workplace of workers as well as minimize cross-contamination, it is suggested to make use of an independent dust elimination air web, that is, an independent dust elimination system for the feeding port.

2. The very first batching and blending.
The initial batching is generally the prep work of public raw materials, that is, the preparation of bigger products in the formula. This fish feed extruder device procedure is primarily finished by digital batching ranges.
Nevertheless, in the very first batching process, unique focus must be paid to the arching issue of the batching container, which is mostly brought on by the light bulk thickness and bad fluidness of the raw products of the aquatic feed, particularly the state-of-the-art marine feed resources. Therefore, specific anti-arching actions need to be considered the batching container, such as making use of eccentric discharge, vibration electric motor, and so on.
The single-shaft horizontal ribbon mixer can be used for the first mixing, as well as the oil addition system need to be considered on the mixer. The initial batching as well as mixing is also the pre-treatment process of ultra-fine pulverization.
This complementary equipment of fish feed extruder machine is generally to reduce the variation range of product pellet dimension, enhance the working problem of the pulverizer, improve the functioning performance of the pulverizer, and also make certain the high quality of the item.

3. Second squashing as well as mixing of second active ingredients.
Due to the low food intake, short digestion system and also bad digestion ability of marine pets, marine feed needs extremely fine squashing pellet dimension to boost the surface area of the feed, boost the contact location between the digestion juice of marine animals and the feed, as well as enhance the capability of aquatic animals to feed the feed.
At the same time, because of the reduced consumption of water animals, the mixing harmony of the feed is required to be reflected in a smaller sized variety, which additionally calls for the aquatic feed to have a better pellet size.
As an example, the shrimp feed must all travel through the 40-mesh logical filter, and also the material on the 60-mesh screen should be less than 5%, so the micro-grinding procedure has to be adopted.
In the additional pulverization procedure, the products mixed in the first time are raised by the elevator and afterwards get in the silo to be crushed, and after that go into the mini pulverizer. Micro-pulverizers are usually used in the processing of aquatic feeds, as well as vertical-axis micro-pulverizers are generally made use of, which are outfitted with effective wind separation tools, and then go into the rotating grading display for testing.
The objective of configuring the rotating grading screen here is primarily to remove the great fluff formed by the crude fibers in the feed during the pulverization process, due to the fact that the existence of these great fluff is easy to comply with the die hole of the fish feed extruder maker up until the die hole is obstructed, triggering Close down for cleaning, so it needs to be eliminated.
The cleansed products undergo second batching and also blending. Because the excellence of the materials getting in the additional batching blending container is above 60 mesh and the thickness is small, unique attention needs to be paid to the sensation of arching.
In order to avoid this sensation, on the one hand, the eccentric sub-expansion hopper can be utilized, and also on the other hand, all the material discharge equipments that have actually undertaken ultra-fine grinding utilize an impeller feeder, which not just has an arch splitting system, however likewise can flexibly adjust the flow rate. dimension. Different raw materials go into the second mixer after additional batching.
There is an artificial feeding port over the second mixer, which is primarily made use of for the enhancement of trace ingredients. At the same time, there is a liquid addition device on the mixer for the enhancement of oil; one is for the addition of water. In the additional mixing procedure, various materials should be totally blended, as well as the coefficient of variant curriculum vitae is less than 7%, which is the key to guaranteeing product top quality.
For that reason, the mixer needs to select a model with outstanding performance, such as double-shaft horizontal paddle mixing It has high blending uniformity, high outcome as well as quick blending speed. After additional crushing and additional active ingredient mixing, the product gets in the succeeding procedure-- development granulation process-- with fish feed extruder maker.

4. Extrusion process by fish feed extruder device.
In the extrusion process, the material in fact goes through a cooking process under the problems of high temperature, high humidity and high pressure.
During this fish feed extruder equipment process, the physical and chemical buildings of the material changed strongly, and also at the moment when the product was extruded from the die opening, the water in the feed was immediately converted from fluid to gaseous state and also discharged from the feed due to the fact that the stress suddenly dropped from high pressure to concerning 100kPa.
Consequently, the product is extruded by fish feed extruder machine to develop the so-called extruded feed. Since this sort of feed not just has the advantages of general hard pellet feed - great palatability, prevents automatic grading of items, is easy to transfer, helps food digestion, lowers waste in the feeding procedure, etc, but likewise 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 the utilization price of the pet feed is improved; it has excellent floatability, which is easy to observe the feeding situation of the fish, and can manage the water contamination to the optimum level. These are additionally the primary reasons why extruded feed is extensively utilized.
There are lots of sort of dryers can be utilized after fish feed extruder equipment. When the size of the pellets is less than 4mm, a vibrating fluidized bed clothes dryer can be picked; when the size of the pellets is higher than 4mm, a belt clothes dryer can be selected, or a straight float dryer can be directly selected.
Since this sort of clothes dryer can make the product in a semi-suspended state on the entire display surface, it can not only guarantee the drying out result, however additionally decrease the damages to the pellets. After the material is dried out, it enters the exterior spraying system.
The exterior splashing of the pellets is generally to satisfy the fish's energy requirements and lower the loss of heat-sensitive materials during processing. The nutrients that ought to not be included the previous process can be supplemented by outside splashing, and at the same time, the palatability of the feed can be improved as well as the powder material can be reduced.
The maximum functioning temperature level for this procedure is around 80 ℃. After the material travels through the exterior splashing system, it can get in the counter-flow cooler for air conditioning.

5. Finished item packaging.
The cooled material is lifted by the elevator and then crushed right into the aircraft rotary display for classification. The grading sieve utilized after fish feed extruder machine is typically a two-layer sieve, and also the product on the lower screen is the finished product, which can be straight become part of the completed product storage facility, and after that evaluated and also packaged. The product on the top screen requires to be returned to the crusher for crushing. The product under the reduced filter is typically finely smashed, which can be returned to the batching container as waste.
The fish feed extruder equipment manufacturing process examined above is the conventional setup of the existing water extruded feed processing modern technology. Using this procedure, sinking feed, slow-moving sinking feed and floating feed can be created.
Although extruded fish feed extruder machine innovation has actually been recognized by many makers as a new sort of handling innovation, it has actually not been widely utilized due to the fact that its financial investment is much larger than that of difficult pellet feed processing innovation.
Nevertheless, the fish feed extruder machine blowing procedure is the future advancement trend of the feed processing market, specifically in the application of aquatic pet feed and also pet dog feed, and will definitely change the standard hard pellet feed processing modern technology.
