Detailed Description

With the rapid development of the aquaculture industry,  standard farming  techniques have been  much from  satisfying people's  requirements. The  demands for aquaculture fish feed made by fish feed extruder  equipment are not  just balanced nutrition, good  security of the feed in water, no  contamination to water  top quality, etc,  as well as  extra  strict  demands are  advanced for the  ecological quality of fish survival.

The feed produced by the aquaculture fish feed extruder machine is  tough pellets, and the  various other is the extruded feed pellet  device, and the processed fish feed is soft pellets.

Today, Richi  Equipment  will certainly talk about the extruded feed fish feed extruder  equipment. The production process  normally  takes on  second  squashing and  additional ingredient  blending,  and after that  goes through extrusion,  drying out,  outside spraying, cooling, crushing and  evaluating to  finish the  handling of  water extruded feed.

1.  Resources  cleansing and primary grinding.

There are  usually  2 forms of raw materials  made use of in floating fish feed  manufacturing facilities: one is powder, which does not need to be coarsely pulverized. For this  type of  resources, it can directly  go into the  cone-shaped  cleansing screen to remove  contaminations after  going through the feeding pit  and also elevator,  and afterwards conduct magnetic separation, and  straight  go into the batching bin through the distributor or screw auger to participate in the  initial batching;.

The  product that needs to be coarsely pulverized-- granular  product. This  sort of  product  gets in the  cleansing equipment  via the  dumping pit and the elevator to  go into the  cleansing  tools for magnetic  splitting up of  pollutants,  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 crushed after magnetic  splitting up without  preliminary sieving.

 Single coarse pulverization is the pretreatment  procedure of ultrafine pulverization in aquatic feed processing. Its main  function is to  minimize the pellet  dimension  distinction and  variant range of materials,  enhance the working condition of the ultrafine pulverizer,  as well as improve the working efficiency  as well as  assurance of the ultrafine pulverizer.

The product  high quality is stable; at the same time, in order to  enhance the  workplace of  employees  as well as  lower cross-contamination, it is  advised to  utilize an independent  dirt  elimination air net, that is, an independent  dirt removal system for the feeding port.

2. The first batching and  blending.

The first batching is  primarily the  prep work of public  resources, that is, the  prep work of larger materials in the formula. This fish feed extruder machine  procedure is  mostly completed by electronic batching  ranges.

However, in the first batching  procedure,  unique attention  must be paid to the arching  trouble of the batching bin, which is  mostly  triggered by the light  mass  thickness  as well as poor  fluidness of the raw  products of the aquatic feed,  specifically the  state-of-the-art  water feed raw materials.  As a result, certain anti-arching  steps should be  considered the batching bin, such as  making use of eccentric discharge,  resonance  electric motor, etc.

The single-shaft  straight ribbon mixer can be  utilized for the  very first  blending, and the  oil  enhancement system must 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  complementary  devices of fish feed extruder  device is  mostly to reduce the variation  series of material pellet  dimension,  enhance the  functioning  problem of the pulverizer,  boost the working  effectiveness of the pulverizer,  as well as  make certain the  high quality of the product.

3.  Additional  squashing  as well as  blending of  additional  components.

 Because of the low food  consumption,  brief  gastrointestinal  system  and also  inadequate digestive ability of aquatic animals,  water feed  needs  extremely fine  squashing pellet size to  raise the surface area of the feed, increase the contact  location  in between the  gastrointestinal juice of  water  pets and the feed,  and also  boost the  capacity of  water  pets to feed the feed.

At the same time, due to the  reduced  consumption of aquatic  pets, the mixing uniformity of the feed is  needed to be reflected in a  smaller sized  array, which  additionally requires the  water feed to have a finer pellet  dimension.

 For instance, the shrimp feed should all  go through the 40-mesh  logical sieve, and the  material on the 60-mesh  screen  must be less than 5%, so the micro-grinding  procedure must be  embraced.

In the  additional pulverization process, the  products mixed in the first time are  raised by the  lift and then  go into the silo to be pulverized,  and after that enter the micro pulverizer. Micro-pulverizers are generally  utilized in the  handling of  water feeds,  and also vertical-axis micro-pulverizers are  usually  utilized, which are  outfitted with  effective wind separation  tools,  and after that  get in the  rotating grading screen for screening.

The  function of  setting up the rotary grading  display  right here is  generally to remove the fine fluff  developed by the  crude fibers in the feed during the pulverization  procedure,  since the  presence of these fine fluff is  simple to  comply with the die  opening of the fish feed extruder  equipment until the die hole is  obstructed,  triggering  Close down for cleaning, so it must be removed.

The  cleaned up materials  go through  second batching  as well as mixing. Since the  excellence of the  products  getting in the  additional batching  blending  container is above 60 mesh  and also the  thickness is  little,  unique  interest should be paid to the  sensation of arching.

In order to  stop this  sensation, on the one hand, the eccentric sub-expansion  receptacle can be  made use of, and on the other hand, all the  product discharge  equipments that have  gone through ultra-fine grinding  make use of an impeller feeder, which not only has an arch  splitting mechanism,  however  additionally can flexibly  readjust the  circulation rate.  dimension.  Different  basic materials  get in the secondary mixer after secondary batching.

There is an artificial feeding port  over the  additional mixer, which is  primarily  utilized for the  enhancement of trace additives. At the same time, there is a  fluid  enhancement mechanism on the mixer for the addition of  oil; one is for the  enhancement of water. In the  additional  blending  procedure,  numerous  products  have to be fully  blended,  and also the coefficient of variation  curriculum vitae is less than 7%, which is the  essential to ensuring product  high quality.

 For that reason, the mixer  has to  pick a model with  exceptional performance, such as double-shaft horizontal paddle  blending It has high  blending uniformity, high  outcome  and also  quick  blending speed. After  second  squashing  as well as secondary  active ingredient  blending, the  product  goes into the  succeeding  procedure--  development granulation  procedure-- with fish feed extruder  equipment.

4. Extrusion process by fish feed extruder machine.

In the extrusion  procedure, the material  in fact  goes through a cooking  procedure under the conditions of  heat, high humidity and high pressure.

 Throughout this fish feed extruder  equipment process, the physical  and also chemical  residential or commercial properties of the material  transformed strongly,  as well as  presently when the  product was  squeezed out from the die hole, the water in the feed was immediately converted from  fluid to gaseous state and emitted from the feed because the  stress  unexpectedly  went down from high pressure to  regarding 100kPa.

 Thus, the  product is  squeezed out by fish feed extruder machine to  create the so-called extruded feed. Because this kind of feed not  just has the advantages of  basic  difficult pellet feed -  excellent palatability, avoids automatic grading of  items, is  simple to  move,  aids digestion,  minimizes waste in the feeding process, etc, but  additionally has  one-of-a-kind advantages:.

In the feed, the starch has a high degree of gelatinization by fish feed extruder  equipment, the protein is  a lot more digestible,  as well as the utilization  price of the animal feed is  enhanced; it has  superb floatability, which is  simple to observe the feeding  scenario of the fish, and can control the water pollution to the maximum extent. These are  additionally the main  reasons that extruded feed is  commonly used.

There are  numerous  type of dryers can be  utilized after fish feed extruder  maker. When the  size of the pellets is less than 4mm, a vibrating fluidized bed dryer can be  chosen; when the diameter of the pellets is greater than 4mm, a belt  clothes dryer can be selected, or a horizontal float  clothes dryer can be directly  chosen.

 Since this  sort of  clothes dryer can make the material in a semi-suspended state on the entire screen surface, it can not only ensure the  drying out effect, but  likewise  reduce the  damages to the pellets. After the material is dried, it  gets in the  exterior  splashing system.

The  exterior  splashing of the pellets is mainly to  satisfy the fish's  power  requirements and  decrease the loss of heat-sensitive  compounds  throughout processing. The nutrients that  must not be added in the previous process can be supplemented by  exterior  splashing,  and also at the same time, the palatability of the feed can be  boosted  and also the powder content can be reduced.

The  optimal  functioning  temperature level for this  procedure is around 80 ℃. After the material passes through the  exterior  splashing system, it can enter the counter-flow cooler for cooling.

5. Finished  item packaging.

The cooled  product is lifted by the elevator and then crushed into the  airplane  rotating screen for  category. The  rating  filter  made use of after fish feed extruder  device is  usually a two-layer  filter, and the  product on the  reduced sieve is the finished  item, which can be  straight  participated in the  completed product  storage facility,  and after that  evaluated  as well as packaged. The material on the upper  screen needs to be returned to the crusher for  squashing. The  product under the lower sieve is  typically  carefully crushed, which can be returned to the batching  container as waste.

The fish feed extruder machine  manufacturing process  examined above is the  standard  arrangement of the  existing aquatic extruded feed  handling technology.  Utilizing this process, sinking feed, slow sinking feed  and also floating feed can be  generated.

Although extruded fish feed extruder machine  modern technology has been  acknowledged by  several manufacturers as a  brand-new  sort of  handling  modern technology, it  has actually not been  extensively used  due to the fact that its investment is much larger than that of  tough pellet feed processing  modern technology.

Nevertheless, the fish feed extruder  maker  blowing  procedure is the future  advancement trend of the feed  handling industry,  particularly in the application of  marine  pet feed and  pet dog feed, and will  certainly  change the  typical  difficult pellet feed processing technology.

I  really hope the above  relevant content  concerning fish feed extruder  device is  handy to you.  For additional information  concerning  drifting fish feed granulator  equipment, you  rate to consult the staff of Richi  Equipment, we will  offer you wholeheartedly!
