Drifting fish feed pellet extruder  innovation

In the production of extruded feed, the main  devices is a screw fish feed pellet extruder. The material is fed into the fish feed pellet extruder,  and also the screw screw pushes the  product to form an axial  circulation.

At the same time,  because of the mechanical friction  in between the screw  and also the  product, the material  and also the barrel, and the  product inside the  product, the material is  highly  pressed, stirred, and sheared,  and also  because of this, the material is  more refined  as well as homogenized.

As the  stress  progressively increases, the temperature increases  as necessary. When the paste material is ejected from the die hole, under the  activity of a strong  stress difference, the material is puffed by floating fish feed making  maker, dehydrated  as well as cooled. The puffed  item  hangs,  permeable, crisp, and has good palatability and  taste.

The fish feed pellet extruder  blowing technology breaks through the traditional processing technology, makes the physical  homes of the feed  adjustment qualitatively, greatly  advertises the development of the feed processing  sector and the breeding  sector,  and also is a major  development in the feed  sector.

https://www.apsense.com/user/richimanufaktur  feed pellet extruder  blowing process is a  procedure that integrates  different operations such as mixing, kneading, shearing, heating, and  air conditioning. The following is a specific analysis from the  facets of density control,  automated control  as well as energy  conserving  and also  usage  decrease.

1.  Thickness control  innovation

In the extrusion process of fish feed pellet extruder, there are many factors that  impact the density of feed, such as  refining  innovation, fish feed pellet extruder  tools,  refining  criteria, process control, feed raw materials, formula  and so forth.

It is  viable to control the  item density by changing the raw material or formula,  yet it has little application  worth; by  altering the screw  setup, the  thickness control of the extruded feed  item can be  understood,  however the  procedure is inconvenient. Density control can  additionally be achieved by  changing the operating  specifications.

In addition, in the fish feed pellet extruder  handling of  water feed, in order to meet the feeding  needs of  marine animals, the ups  and also downs of  water feed  ought to be  regulated,  and also the ups and downs of feed are  very closely related to  thickness, so  thickness control is  used in the  manufacturing of  marine extruded feed.

Innovation is particularly important.  Presently,  managing the density of extruded products is mainly  attained by  regulating the  stress  as well as  temperature level. The  major  techniques are as  complies with:

( 1 ) Open up a pressure relief  opening on the extruding  dental caries,  as well as  connect the pressure relief hole when producing floating feed, so as to meet the  demands of  heat and high pressure for processing  drifting feed.

Open the pressure relief hole when feeding,  to make sure that when the material  gets to the pressure relief hole, the pressure in the sleeve is  partly released, and at the same time, some water vapor is  likewise  released from the pressure  alleviation  opening.


These materials are  squeezed out by fish feed pellet extruder to the end of the extruding  dental caries  and afterwards  compressed to  get a heavy feed with high bulk  thickness. This pressure relief  opening can  additionally be  utilized to  leave,  to make sure that the material  sheds part of the water vapor during the forced  activity.

This fish feed pellet extruder  procedure  technique  recognizes the control of the density of the extruded  item by controlling the pressure in the extruding cavity, and the output  will certainly not be  impacted  due to the fact that the feeding  quantity does not  require to be  minimized.

( 2) A  stress  managing  tool is added in the floating fish feed extruder  maker (pressurization before the die). The pressure  guideline of the fish feed pellet extruder is to  set up a shut-off valve  in between the extrusion  dental caries  as well as the discharge  theme to  readjust the  stress difference between the extrusion  tooth cavity and the outside of the extrusion  dental caries.

( 2 ) Stress  reducing  modern technology (post-mold pressure). A  brand-new  kind of  thickness control system was developed for aquafeed. This density control system of fish feed pellet extruder adopts pressurized  reducing technology to  keep a  specific positive  stress in the  reducing chamber.

When the  product  gets in the  reducing chamber from the puffing chamber, since the boiling point of water  raises with the  stress, the flash  dissipation can be reduced to control the degree of expansion of the  product, and the starch molecules are  quickly  strengthened in the  reducing chamber,  as well as the  product  no more enters the normal pressure from the  reducing chamber.

The  favorable pressure of the  reducing chamber can be  recognized by inputting  pressed air with an air pump, and the fan can be  switched off when discharging.

This fish feed pellet extruder  procedure  approach avoids  managing other  elements that  impact the degree of  growth,  consequently  decreasing the  requirement for  hands-on operation,  and also at the same time, the controllability is  more powerful than other  techniques.

Currently, this  brand-new fish feed pellet extruder  modern technology  has actually not been  used in China, but this technology is superior to the exhaust  approach in  regards to density control of extruded products and  procedure  as well as use,  and also is a  brand-new  instructions for the  growth of extruded  modern technology.

( 4) Controlling the opening  price of the  layout. By changing the opening  price of the discharge template, the pressure  distinction before and after the  theme can be changed, so as to  accomplish the  function of controlling the  thickness of the  item. The hole is blocked.

2. Automatic control of fish feed extrusion process

The  automated control of the fish feed pellet extruder extrusion process  describes the  quick  and also  accurate control of the process parameters by  outfitting the extrusion  devices with a computer-aided control system.

The application of automatic control technology in the fish feed pellet extruder  blowing process can not only improve  job  effectiveness,  yet  likewise  boost  item  top quality  security. Models of automatic control  in your home and abroad

There are  researches on all sides. The automatic control  innovation of the fish feed pellet extruder puffing  procedure  has actually made  excellent  progression,  as well as a visualization control system of the puffing process  has actually been  established. The  squeezing out system of fish feed pellet extruder based on  solution  commercial  arrangement  software program  understands the  aesthetic control of the  squeezing out  procedure

The  sensing unit can be used to  perform on-site detection  as well as  comments on the operating  criteria of the fish feed pellet extruder, automatically adjust the  pertinent working  criteria of the floating fish feed pellet  device, and realize various  predetermined by the operator.

Working  specifications, with formula  storage space, report printing, alarm,  vibrant  screen  and also recording of  functioning parameters. Foreign computer  automated control  modern technology  has actually already been  used in the field of feed processing

In the entire fish feed pellet extruder process, it  has actually been developed from a  solitary  computer system control system to an  innovative  automated control system, which can  show color  pictures in the  main control  area, computer program control  and also  interaction network for  drifting fish feed making machine  procedure, it can complete all production  treatments without unmanned  procedure.

In general, the automatic control of puffing in feed  handling abroad  has actually been developing towards the  instructions of combining with product  top quality.

While the introduction of  computer systems in my  nation is mainly to solve the  issue of  manufacturing automation,  just  concentrating on the monitoring of equipment operation in the  manufacturing process and the control of stand-alone  devices. It  has actually not played its due  duty in improving product  top quality  and also other aspects.

3.   biomass pelletizer saving in extrusion  procedure.

The problem of energy  conserving  and also  usage  decrease is the research  emphasis in the fish feed pellet extruder extrusion  procedure.

Currently, it is  primarily  via the  study of low energy  usage processing  innovation  as well as the influence of  primary  procedure  criteria on  power  usage,  and also the establishment of  equivalent mathematical  versions to achieve the  objective of  power saving  as well as  usage  decrease.

In order to  lower the energy  usage in the fish feed pellet extruder puffing  procedure, some domestic feed  makers mainly take measures from the process. For example, in the production process of suckling pig feed, the corn  resources used is not full puffed material,  yet part of the puffed  product  as well as part of the conventional material.

In the later fish feed pellet extruder granulation  procedure,  procedures such as expansion  as well as  reduced  temperature level granulation are used to  make certain that the energy  intake  each product is  decreased.

From the above analysis, it can be seen that it is still a bottleneck  trouble  exactly how the process  criterion  research study in the fish feed pellet extruder puffing process can be embodied in  lowering energy  intake  and also can be realized in actual production.
