With the quick development of the tank farming sector, standard farming methods have actually been much from fulfilling people's demands. The needs for tank farming fish feed made by fish feed extruder machine are not just balanced nutrition, good security of the feed in water, no air pollution to water quality, etc, as well as more rigorous demands are advanced for the ecological top quality of fish survival.
The feed created by the aquaculture fish feed extruder machine is difficult pellets, and also the other is the extruded feed pellet equipment, as well as the processed fish feed is soft pellets.
Today, Richi Machinery will certainly talk about the extruded feed fish feed extruder maker. The manufacturing process usually embraces second crushing and secondary active ingredient blending, and then travels through extrusion, drying out, exterior splashing, cooling, crushing as well as evaluating to finish the handling of water extruded feed.

1. Basic material cleansing and key grinding.
There are usually two types of raw materials used in floating fish feed factories: one is powder, which does not require to be coarsely pulverized. For this type of resources, it can directly get in the cone-shaped cleaning screen to get rid of impurities after travelling through the feeding pit as well as elevator, and then carry out magnetic splitting up, as well as straight enter the batching bin with the distributor or screw auger to join the very first batching;.
The material that requires to be coarsely shattered-- granular product. This kind of material enters the cleaning equipment via the unloading pit as well as the elevator to go into the cleaning tools for magnetic splitting up of contaminations, and afterwards enters the to-be-pulverized container.
For specific resources, such as shrimp shells, they can be straight taken into the silo to be squashed after magnetic separation without initial sieving.
Single rugged pulverization is the pretreatment process of ultrafine pulverization in marine feed handling. Its primary objective is to lower the pellet dimension distinction and variation range of products, enhance the working problem of the ultrafine pulverizer, and improve the functioning effectiveness and also warranty of the ultrafine pulverizer.
The product top quality is secure; at the same time, in order to improve the working environment of employees and also decrease cross-contamination, it is recommended to utilize an independent dirt removal air internet, that is, an independent dust elimination system for the feeding port.

2. The first batching and also blending.
The initial batching is mainly the prep work of public resources, that is, the prep work of larger materials in the formula. This fish feed extruder equipment process is mainly completed by electronic batching scales.
However, in the very first batching procedure, unique interest needs to be paid to the arching trouble of the batching container, which is mostly caused by the light mass density and bad fluidness of the raw materials of the aquatic feed, particularly the top-quality marine feed basic materials. Therefore, specific anti-arching steps need to be taken for the batching bin, such as using eccentric discharge, vibration electric motor, etc.
The single-shaft straight bow mixer can be utilized for the first blending, and also the oil enhancement system should be thought about on the mixer. The initial batching and also blending is additionally the pre-treatment procedure of ultra-fine pulverization.
This supporting tools of fish feed extruder device is primarily to minimize the variant range of product pellet size, enhance the functioning problem of the pulverizer, improve the functioning performance of the pulverizer, and make certain the top quality of the product.

3. Second squashing and mixing of second active ingredients.
As a result of the low food consumption, short gastrointestinal tract as well as bad digestive capacity of marine pets, marine feed calls for very great crushing pellet size to raise the surface of the feed, enhance the get in touch with location in between the digestive system juice of water animals as well as the feed, and also improve the capacity of water animals to feed the feed.
At the same time, due to the reduced intake of water animals, the mixing uniformity of the feed is required to be mirrored in a smaller variety, which also requires the aquatic feed to have a better pellet dimension.
As an example, the shrimp feed ought to all go through the 40-mesh logical screen, as well as the material on the 60-mesh screen must be less than 5%, so the micro-grinding process should be taken on.
In the additional pulverization procedure, the materials mixed in the very first time are raised by the elevator and afterwards go into the silo to be crushed, and afterwards go into the mini pulverizer. Micro-pulverizers are normally utilized in the processing of water feeds, and vertical-axis micro-pulverizers are typically used, which are furnished with powerful wind separation tools, and after that get in the rotary grading display for screening.
The purpose of configuring the rotary grading display here is primarily to eliminate the great fluff developed by the coarse fibers in the feed throughout the pulverization process, because the existence of these great fluff is very easy to stick to the die opening of the fish feed extruder device until the die opening is blocked, creating Close down for cleaning, so it needs to be eliminated.
The cleaned materials are subjected to second batching and also blending. Because the excellence of the materials entering the secondary batching mixing bin is above 60 mesh and also the thickness is tiny, unique attention should be paid to the phenomenon of arching. try this site
In order to prevent this sensation, on the one hand, the eccentric sub-expansion receptacle can be used, and also on the other hand, all the material discharge devices that have undertaken ultra-fine grinding use an impeller feeder, which not just has an arch breaking device, however additionally can flexibly readjust the circulation rate. size. Numerous basic materials go into the secondary mixer after secondary batching.
There is an artificial feeding port above the second mixer, which is mostly used for the addition of trace additives. At the same time, there is a liquid addition device on the mixer for the addition of grease; one is for the addition of water. In the second blending procedure, numerous products must be totally combined, and the coefficient of variant CV is less than 7%, which is the crucial to ensuring item top quality.
Consequently, the mixer has to pick a model with excellent performance, such as double-shaft horizontal paddle mixing It has high mixing uniformity, high outcome and also quick blending speed. After second crushing and also secondary ingredient mixing, the product goes into the succeeding procedure-- growth granulation process-- with fish feed extruder maker.
4. Extrusion process by fish feed extruder device.
In the extrusion process, the product actually undertakes a cooking process under the problems of heat, high moisture and high pressure.
During this fish feed extruder device process, the physical and also chemical buildings of the product changed highly, and also right now when the product was squeezed out from the die opening, the water in the feed was quickly converted from liquid to aeriform state as well as given off from the feed since the stress all of a sudden dropped from high pressure to about 100kPa.
Thereby, the product is extruded by fish feed extruder device to form the supposed extruded feed. Because this kind of feed not only has the advantages of basic hard pellet feed - excellent palatability, prevents automated grading of products, is simple to deliver, assists digestion, lowers waste in the feeding procedure, and so on, however likewise has special advantages:.
In the feed, the starch has a high level of gelatinization by fish feed extruder machine, the healthy protein is much more digestible, and the use price of the animal feed is boosted; it has exceptional floatability, which is very easy to observe the feeding situation of the fish, and can regulate the water pollution to the maximum degree. These are likewise the main reasons why extruded feed is widely made use of.
There are many kinds of clothes dryers can be utilized after fish feed extruder maker. When the diameter of the pellets is less than 4mm, a shaking fluidized bed dryer can be picked; when the diameter of the pellets is more than 4mm, a belt dryer can be selected, or a straight float clothes dryer can be straight selected.
Because this type of dryer can make the material in a semi-suspended state on the whole screen surface, it can not just make sure the drying out result, however also lessen the damage to the pellets. After the material is dried out, it gets in the exterior splashing system.
The outside splashing of the pellets is primarily to satisfy the fish's power demands and also lower the loss of heat-sensitive compounds throughout processing. The nutrients that ought to not be added in the previous procedure can be supplemented by outside spraying, as well as at the same time, the palatability of the feed can be boosted as well as the powder content can be decreased.
The maximum working temperature for this procedure is around 80 ℃. After the material travels through the external splashing system, it can enter the counter-flow colder for air conditioning.
5. Finished product packaging.
The cooled down material is raised by the lift and after that crushed into the plane rotary display for category. The rating filter utilized after fish feed extruder equipment is typically a two-layer sieve, and also the product on the reduced filter is the ended up product, which can be directly entered into the ended up item stockroom, and then considered and also packaged. The product on the top filter needs to be gone back to the crusher for squashing. The material under the reduced sieve is usually carefully smashed, which can be returned to the batching container as waste.
The fish feed extruder maker production procedure evaluated above is the standard arrangement of the existing marine extruded feed handling technology. Using this procedure, sinking feed, sluggish sinking feed and also drifting feed can be created.
Although extruded fish feed extruder machine technology has been identified by lots of producers as a brand-new type of processing technology, it has not been widely utilized due to the fact that its investment is much larger than that of difficult pellet feed processing modern technology.
Nonetheless, the fish feed extruder machine blowing process is the future advancement trend of the feed handling sector, particularly in the application of marine pet feed and also family pet feed, and will definitely replace the traditional hard pellet feed processing innovation.
I really hope the above related web content concerning fish feed extruder device is practical to you. To find out more about drifting fish feed granulator maker, you are welcome to get in touch with the personnel of Richi Machinery, we will certainly serve you wholeheartedly!
