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.
