1. Thickness control technology
In the extrusion procedure of fish feed pellet extruder, there are several elements that influence the density of feed, such as refining modern technology, fish feed pellet extruder devices, processing criteria, procedure control, feed basic materials, formula and more.
It is possible to regulate the product density by transforming the raw material or formula, however it has little application value; by transforming the screw configuration, the thickness control of the extruded feed item can be understood, however the operation is troublesome. Density control can additionally be accomplished by changing the operating criteria.
In addition, in the fish feed pellet extruder handling of water feed, in order to meet the feeding requirements of marine pets, the ups and also downs of water feed must be regulated, and also the ups and downs of feed are closely pertaining to thickness, so density control is applied in the production of water extruded feed.
Technology is particularly vital. Presently, managing the density of extruded products is mainly achieved by controlling the stress and temperature. The major approaches are as follows:

( 1 ) Open up a stress relief hole on the squeezing out cavity, as well as plug the pressure alleviation hole when generating floating feed, so as to meet the requirements of high temperature and high pressure for processing drifting feed.
Open the stress relief opening when feeding, to ensure that when the product reaches the pressure relief opening, the pressure in the sleeve is partly launched, and also at the same time, some water vapor is also discharged from the pressure alleviation opening.
These products are extruded by fish feed pellet extruder to the end of the extruding tooth cavity and then compacted to obtain a hefty feed with high mass density. This stress relief opening can additionally be used to leave, to ensure that the product loses part of the water vapor throughout the forced activity.
This fish feed pellet extruder procedure technique realizes the control of the thickness of the extruded item by controlling the stress in the extruding tooth cavity, and the outcome will certainly not be impacted due to the fact that the feeding quantity does not require to be decreased.
( 2) A pressure managing tool is added in the drifting fish feed extruder equipment (pressurization before the die). The stress regulation of the fish feed pellet extruder is to mount a shut-off valve in between the extrusion cavity as well as the discharge theme to change the pressure difference between the extrusion tooth cavity and also the beyond the extrusion cavity.
(3 )Pressure reducing technology (post-mold pressure). A brand-new type of density control system was developed for aquafeed. This thickness control system of fish feed pellet extruder embraces pressurized cutting technology to keep a specific favorable stress in the reducing chamber.

When the material goes into the cutting chamber from the puffing chamber, because the boiling point of water increases with the pressure, the flash evaporation can be minimized to manage the level of development of the material, and the starch molecules are instantaneously solidified in the cutting chamber, and also the material no more gets in the typical stress from the reducing chamber.
The favorable stress of the reducing chamber can be recognized by inputting compressed air with an air pump, and the fan can be turned off when discharging.
This fish feed pellet extruder procedure approach avoids regulating various other aspects that affect the level of expansion, thus minimizing the demand for hands-on procedure, and at the same time, the controllability is more powerful than various other methods.
At present, this brand-new fish feed pellet extruder modern technology has not been applied in China, however this technology transcends to the exhaust approach in regards to density control of extruded products as well as procedure as well as use, and also is a new instructions for the advancement of extruded modern technology.
( 4) Regulating the opening price of the theme. By altering the opening rate of the discharge template, the pressure difference before as well as after the design template can be altered, so as to attain the function of regulating the thickness of the product. The hole is obstructed.
2. Automatic control of fish feed extrusion procedure
The automatic control of the fish feed pellet extruder extrusion process describes the quick and also exact control of the procedure parameters by furnishing the extrusion equipment with a computer-aided control system.
The application of automated control technology in the fish feed pellet extruder blowing process can not just enhance job efficiency, but additionally improve product quality stability. Designs of automated control at home as well as abroad
There are research studies on all sides. The automatic control modern technology of the fish feed pellet extruder puffing process has actually made excellent development, as well as a visualization control system of the puffing process has actually been developed. The extruding system of fish feed pellet extruder based on repair industrial arrangement software application recognizes the visual control of the squeezing out procedure
The sensor can be made use of to carry out on-site discovery as well as feedback on the operating parameters of the fish feed pellet extruder, automatically adjust the relevant functioning specifications of the drifting fish feed pellet machine, as well as realize numerous preset by the driver.
Functioning criteria, with formula storage space, report printing, alarm system, dynamic display and recording of working parameters. International computer system automatic control modern technology has actually already been applied in the field of feed handling
In the entire fish feed pellet extruder process, it has been developed from a single computer system control system to an advanced automatic control system, which can present shade images in the main control space, computer program control as well as interaction network for floating fish feed making device procedure, it can complete all production treatments without unmanned procedure.
In general, the automated control of blowing in feed processing abroad has been developing towards the instructions of incorporating with item quality.
While the introduction of computer systems in my country is mostly to resolve the problem of production automation, just concentrating on the tracking of tools procedure in the manufacturing procedure and the control of stand-alone tools. It has actually not played its due role in improving item high quality and other aspects.
3. Power conserving in extrusion procedure.
The issue of energy conserving and intake reduction is the research study emphasis in the fish feed pellet extruder extrusion process.
Presently, it is generally with the research of low energy consumption processing modern technology as well as the impact of major process criteria on power intake, and also the establishment of corresponding mathematical designs to attain the purpose of power saving and consumption reduction.
In order to decrease the energy usage in the fish feed pellet extruder blowing procedure, some residential feed makers mainly take measures from the process. For example, in the manufacturing procedure of nursing pig feed, the corn basic material used is not full puffed material, however part of the puffed product and part of the conventional product.
In the later fish feed pellet extruder granulation process, processes such as growth as well as low temperature granulation are used to make certain that the power intake per unit item is minimized.
From the above evaluation, it can be seen that it is still a bottleneck problem exactly how the procedure specification research in the fish feed pellet extruder puffing process can be personified in decreasing power intake and can be realized in actual production.
