In the production of extruded feed, the primary tools is a screw fish feed pellet extruder. The product is fed right into the fish feed pellet extruder, and the screw screw presses the product to develop an axial circulation.
At the same time, as a result of the mechanical friction between the screw and also the product, the material and also the barrel, and also the product inside the product, the material is highly squeezed, mixed, as well as sheared, and consequently, the material is additional fine-tuned as well as homogenized.
As the pressure slowly enhances, the temperature boosts accordingly. When the paste material is expelled from the die hole, under the activity of a strong stress distinction, the material is puffed by drifting fish feed making maker, dehydrated and also cooled down. wood pellet machine in Algeria puffed product is loose, porous, crisp, and also has excellent palatability as well as taste.
The fish feed pellet extruder puffing modern technology breaks through the traditional processing innovation, makes the physical buildings of the feed modification qualitatively, significantly advertises the advancement of the feed handling market and also the reproducing market, and is a significant technology in the feed market.
The fish feed pellet extruder blowing process is a process that incorporates various procedures such as blending, working, shearing, home heating, and also air conditioning. The following is a details evaluation from the elements of density control, automatic control and also energy saving and also consumption decrease.
1. Density control technology
In the extrusion procedure of fish feed pellet extruder, there are numerous variables that affect the density of feed, such as processing modern technology, fish feed pellet extruder tools, processing parameters, process control, feed resources, formula and so on.
It is possible to control the product thickness by changing the raw material or formula, yet it has little application value; by changing the screw configuration, the density control of the extruded feed item can be recognized, however the operation is bothersome. Density control can likewise be attained by readjusting the operating parameters.
Furthermore, in the fish feed pellet extruder processing of water feed, in order to fulfill the feeding demands of aquatic animals, the ups and downs of aquatic feed should be regulated, and the ups as well as downs of feed are very closely pertaining to thickness, so density control is applied in the production of water extruded feed.
Technology is particularly important. Presently, regulating the density of extruded items is generally achieved by regulating the pressure and also temperature. The main approaches are as follows:
( 1 ) Open up a stress alleviation opening on the extruding cavity, and also plug the pressure alleviation opening when producing floating feed, so as to satisfy the demands of high temperature and high pressure for processing drifting feed.
Open up the pressure relief hole when feeding, to make sure that when the material gets to the stress relief hole, the pressure in the sleeve is partially launched, and at the same time, some water vapor is likewise discharged from the stress alleviation opening.
These materials are squeezed out by fish feed pellet extruder to the end of the squeezing out cavity and after that compacted to obtain a heavy feed with high mass density. This stress alleviation opening can additionally be utilized to leave, to make sure that the product loses part of the water vapor throughout the forced movement.
This fish feed pellet extruder process method understands the control of the density of the extruded item by controlling the stress in the squeezing out tooth cavity, and the outcome will not be affected because the feeding quantity does not need to be lowered.
( 2) A stress regulating gadget is added in the drifting fish feed extruder maker (pressurization prior to the die). The pressure law of the fish feed pellet extruder is to mount a shut-off valve between the extrusion cavity and the discharge template to readjust the stress difference in between the extrusion tooth cavity as well as the outside of the extrusion cavity.
( 2 )Pressure cutting innovation (post-mold stress). A brand-new type of thickness control system was developed for aquafeed. This thickness control system of fish feed pellet extruder takes on pressurized reducing innovation to keep a certain positive stress in the cutting chamber.
When the product enters the reducing chamber from the puffing chamber, because the boiling point of water increases with the stress, the flash dissipation can be reduced to regulate the level of development of the material, as well as the starch particles are immediately solidified in the cutting chamber, as well as the product no longer goes into the regular pressure from the cutting chamber.
The positive pressure of the reducing chamber can be realized by inputting pressed air with an air pump, and the follower can be shut off when releasing.
This fish feed pellet extruder procedure method avoids regulating other variables that affect the degree of development, thus reducing the need for hand-operated procedure, and also at the same time, the controllability is more powerful than various other approaches.
Today, this new fish feed pellet extruder innovation has not been used in China, however this innovation transcends to the exhaust technique in regards to density control of extruded items and also procedure and also usage, and also is a new instructions for the advancement of extruded modern technology.
( 4) Regulating the opening price of the design template. By changing the opening price of the discharge template, the stress difference prior to and after the template can be transformed, so regarding attain the objective of controlling the thickness of the product. The hole is blocked.
2. Automatic control of fish feed extrusion procedure
The automatic control of the fish feed pellet extruder extrusion process refers to the rapid and also exact control of the process criteria by gearing up the extrusion tools with a computer-aided control system.
The application of automatic control technology in the fish feed pellet extruder puffing process can not only enhance work effectiveness, but additionally improve product top quality stability. Versions of automated control at home and also abroad
There are researches on all sides. The automated control modern technology of the fish feed pellet extruder blowing process has actually made fantastic progress, and a visualization control system of the puffing procedure has actually been created. The extruding system of fish feed pellet extruder based upon solution industrial configuration software understands the aesthetic control of the squeezing out process
The sensor can be utilized to conduct on-site discovery as well as responses on the operating parameters of the fish feed pellet extruder, immediately readjust the appropriate functioning criteria of the drifting fish feed pellet device, and also understand various preset by the driver.
Working parameters, with formula storage, record printing, alarm, dynamic screen as well as recording of working parameters. Foreign computer automated control innovation has actually already been applied in the field of feed processing
In the entire fish feed pellet extruder process, it has been created from a single computer system control system to an sophisticated automated control system, which can present shade images in the main control area, computer system program control and also interaction network for floating fish feed making device operation, it can complete all production treatments without unmanned procedure.
Generally, the automatic control of blowing in feed handling abroad has actually been establishing in the direction of the instructions of incorporating with item quality.
While the introduction of computers in my nation is primarily to resolve the trouble of manufacturing automation, just concentrating on the surveillance of devices operation in the manufacturing procedure and the control of stand-alone tools. It has actually not played its due role in boosting product quality as well as various other elements.
3. Power conserving in extrusion process.
The problem of energy saving and consumption decrease is the research study focus in the fish feed pellet extruder extrusion procedure.
Presently, it is mainly with the research study of reduced power consumption handling innovation and the influence of major process parameters on energy intake, as well as the establishment of corresponding mathematical models to achieve the purpose of power conserving and intake decrease.
In order to lower the energy intake in the fish feed pellet extruder blowing process, some domestic feed makers mainly take measures from the process. For example, in the manufacturing procedure of suckling pig feed, the corn basic material made use of is not full puffed product, yet part of the puffed material as well as part of the traditional product.
In the later fish feed pellet extruder granulation procedure, procedures such as expansion and low temperature level granulation are utilized to make sure that the energy consumption each product is reduced.
From the above evaluation, it can be seen that it is still a bottleneck trouble exactly how the process specification research study in the fish feed pellet extruder blowing procedure can be personified in lowering energy consumption as well as can be understood in actual manufacturing.
