Production procedure of fish feed extruder

Production  procedure of fish feed extruder machine

With the rapid  advancement of the aquaculture industry,  standard farming methods  have actually been far from  satisfying people's  requirements. The  needs for aquaculture fish feed made by fish feed extruder machine are not only  well balanced nutrition, good  security of the feed in water, no  air pollution to water  high quality,  and so on, and  extra  rigid  demands are put forward for the environmental quality of fish survival.

The feed produced by the aquaculture fish feed extruder  equipment is  difficult pellets,  as well as the other is the extruded feed pellet  maker,  and also the  refined fish feed is soft pellets.

Today, Richi  Equipment  will certainly  speak about the extruded feed fish feed extruder  equipment. The production process  usually  takes on  additional  squashing  and also  additional ingredient mixing,  and after that passes through extrusion,  drying out, external spraying,  cooling down, crushing and  evaluating to  finish the  handling of  marine extruded feed.

1.  Resources  cleansing  as well as  key grinding.

There are  usually  2 forms of  resources  made use of in  drifting fish feed factories: one is powder, which does not  require to be coarsely pulverized. For this  sort of raw material, it can directly enter the  conelike cleaning screen to  eliminate  contaminations after  going through the feeding pit  and also elevator,  and after that conduct magnetic separation, and  straight  go into the batching bin through the distributor or screw auger to participate in the  very first batching;.

The  product that  requires to be coarsely  crushed-- granular  product. This  type of  product  gets in the cleaning equipment  with the  discharging pit and the  lift to  get in the  cleansing equipment for magnetic separation of  pollutants,  and afterwards  goes into the to-be-pulverized bin.

For  private  basic materials, such as shrimp shells, they can be  straight  taken into the silo to be crushed after magnetic  splitting up without  preliminary sieving.

One-time coarse pulverization is the pretreatment process of ultrafine pulverization in  marine feed processing. Its main  function is to  lower the pellet  dimension  distinction  as well as variation  series of  products,  boost the  functioning condition of the ultrafine pulverizer, and  boost the  functioning  effectiveness and guarantee of the ultrafine pulverizer.

The  item quality is stable; at the same time, in order to  boost the working environment of workers  as well as  decrease cross-contamination, it is  advised to  utilize an independent  dirt removal air  web, that is, an independent dust removal 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 preparation of larger materials in the formula. This fish feed extruder machine process is  generally  finished by  digital batching scales.

 Nevertheless, in the  initial batching  procedure, special attention should be paid to the arching  trouble of the batching  container, which is  primarily  brought on by the light bulk density  and also  inadequate  fluidness of the raw materials of the aquatic feed,  particularly the high-grade aquatic feed  resources.  As a result, certain anti-arching  actions  ought to be  considered the batching  container, such as  making use of eccentric discharge,  resonance motor, etc.

The single-shaft horizontal  bow mixer can be used for the  initial mixing, and the  oil addition system must be  taken into consideration on the mixer. The  initial batching  as well as mixing is  additionally the pre-treatment process of ultra-fine pulverization.

This  supporting  devices of fish feed extruder machine is  mostly to reduce the  variant range of  product pellet  dimension,  boost the working condition of the pulverizer, improve the  functioning  performance of the pulverizer, and  make sure the  high quality of the  item.

3. Secondary  squashing  as well as mixing of  additional ingredients.

Due to the low food intake, short digestive  system  as well as  inadequate digestive ability of aquatic  pets,  water feed  calls for  really fine crushing pellet size to  raise the surface area of the feed,  raise the  call  location  in between the  digestion juice of  marine  pets and the feed,  and also  boost the  capability of  marine  pets to feed the feed.

At the same time,  as a result of the low  consumption of aquatic animals, the mixing uniformity of the feed is  needed to be  shown in a  smaller sized  variety, which  additionally requires the  marine feed to have a  better pellet size.

For example, the shrimp feed should all pass through the 40-mesh analytical  screen,  as well as the content on the 60-mesh sieve  must be less than 5%, so the micro-grinding  procedure  should be  taken on.

In the  second pulverization process, the  products mixed in the  very first time are lifted by the  lift and then enter the silo to be  crushed, and then  go into the  mini pulverizer. Micro-pulverizers are  normally  made use of in the  handling of aquatic feeds,  and also vertical-axis micro-pulverizers are generally  utilized, which are  geared up with  effective wind separation  tools,  and after that  go into the  rotating grading screen for screening.

The purpose of configuring the  rotating grading screen  right here is  mostly to  eliminate the  great fluff  developed by the  rugged fibers in the feed during the pulverization  procedure,  due to the fact that the existence of these  great fluff is easy to  follow the die hole of the fish feed extruder  device  up until the die hole is  obstructed,  creating  Close down for cleaning, so it  has to be  gotten rid of.

The  cleansed  products are subjected to  additional batching  as well as  blending.  Because the fineness of the  products entering the  additional batching mixing  container is above 60 mesh  and also the  thickness is small, special attention should 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 on the other hand, all the material discharge  devices that  have actually  gone through ultra-fine grinding  utilize an impeller feeder, which not only has an arch breaking  system,  however  likewise can flexibly  change the  circulation  price. size.  Numerous  basic materials  go into the  additional mixer after  second batching.

There is an artificial feeding port above the  second mixer, which is  primarily used for the addition of trace  ingredients. At the same time, there is a liquid addition  system on the mixer for the addition of grease; one is for the addition of water. In the  additional  blending  procedure, various  products  should be  completely mixed,  as well as the coefficient of  variant CV is less than 7%, which is the  essential to  making sure product  top quality.

 As a result, the mixer must  select a model with excellent performance, such as double-shaft  straight paddle mixing It has high  blending  harmony, high  outcome  and also  rapid mixing speed. After  additional  squashing  and also  additional  component mixing, the  product enters the  succeeding  procedure-- expansion granulation process-- with fish feed extruder machine.

4. Extrusion process by fish feed extruder  equipment.

In the extrusion  procedure, the material  really undergoes a cooking  procedure under the  problems of  heat, high  moisture  as well as high pressure.

During this fish feed extruder  equipment process, the physical and chemical  residential properties of the  product  transformed  highly, and  presently when the  product was extruded from the die hole, the water in the feed was  promptly converted from liquid to  aeriform state and  released from the feed  since the pressure  instantly  went down from high pressure to  concerning 100kPa.

 Thus, the material is  squeezed out by fish feed extruder  device to  develop the  supposed extruded feed.  Due to the fact that this  type of feed not only has the advantages of  basic  tough pellet feed - good palatability,  prevents  automated grading of  items, is easy to  deliver,  assists digestion,  minimizes waste in the feeding  procedure, etc, but  likewise has  one-of-a-kind advantages:.

In the feed, the starch has a high  level of gelatinization by fish feed extruder  device, the  healthy protein is  much more  absorbable,  as well as the  application  price of the animal feed is  enhanced; it has  exceptional floatability, which is  simple to observe the feeding  scenario of the fish, and can  regulate the water  air pollution to the maximum  degree. These are  likewise the main reasons why extruded feed is  commonly  utilized.

There are  several  type of  clothes dryers can be used after fish feed extruder  device. When the diameter of the pellets is less than 4mm, a vibrating fluidized bed dryer can be  chosen; when the  size of the pellets is  more than 4mm, a belt dryer can be  chosen, or a horizontal float dryer can be directly  picked.

 Since this kind of dryer can make the material in a semi-suspended state on the  whole  display  surface area, it can not  just  make sure the drying  result,  yet  likewise  reduce the  damages to the pellets. After the material is  dried out, it enters the  outside  splashing system.

The  exterior  splashing of the pellets is mainly to meet the fish's energy  demands and  decrease the loss of heat-sensitive  materials during processing. The nutrients that  ought to not be  included the previous process can be supplemented by  exterior spraying,  as well as at the same time, the palatability of the feed can be  enhanced  as well as the powder content can be reduced.

The  optimal  functioning temperature for this process is around 80 ℃. After the material  goes through the  outside  splashing system, it can enter the counter-flow cooler for  air conditioning.

5. Finished product packaging.

The  cooled down  product is lifted by the elevator and then crushed  right into the plane  rotating  display for classification. The  rating  filter used after fish feed extruder  equipment is  normally a two-layer sieve,  as well as the  product on the lower  screen is the finished product, which can be directly  become part of the finished  item  storehouse,  and afterwards  evaluated and packaged. The  product on the  top sieve needs to be returned to the crusher for  squashing. The  product under the lower  filter is  typically  carefully crushed, which can be  gone back to the batching  container as waste.

The fish feed extruder  device production process  examined above is the  standard  setup of the current  marine extruded feed processing technology. Using this  procedure, sinking feed,  sluggish sinking feed and  drifting feed can be produced.

Although extruded fish feed extruder  maker technology  has actually been recognized by  lots of  makers as a new  kind of processing  modern technology, it has not been widely  made use of because its investment is  a lot larger than that of hard pellet feed processing  innovation.

 However, the fish feed extruder  equipment puffing process is the future  growth  pattern of the feed  handling  sector,  particularly in the application of  water  pet feed  as well as  pet dog feed,  as well as will  most definitely  change the  typical hard pellet feed processing  innovation.
