Floating fish feed pellet extruder technology
In the manufacturing of extruded feed, the primary devices is a screw fish feed pellet extruder. The material is fed right into the fish feed pellet extruder, as well as the screw screw pushes the product to develop an axial circulation.
At the same time, as a result of the mechanical rubbing in between the screw and also the product, the product as well as the barrel, and the material inside the material, the product is highly pressed, mixed, and sheared, and therefore, the material is further fine-tuned as well as homogenized.
As the stress gradually increases, the temperature level raises as necessary. When the paste product is expelled from the die hole, under the action of a strong pressure difference, the product is puffed by drifting fish feed making maker, dehydrated and also cooled. The puffed item hangs, permeable, crisp, and also has great palatability and also flavor.
The fish feed pellet extruder puffing technology breaks through the standard processing technology, makes the physical residential or commercial properties of the feed modification qualitatively, greatly advertises the development of the feed handling sector and the reproducing sector, as well as is a significant technology in the feed industry.
The fish feed pellet extruder blowing procedure is a procedure that integrates various operations such as blending, working, shearing, home heating, and also cooling. The following is a details analysis from the elements of thickness control, automated control and also energy conserving and intake decrease.

1. Thickness control modern technology
In the extrusion process of fish feed pellet extruder, there are numerous aspects that affect the density of feed, such as refining technology, fish feed pellet extruder equipment, refining parameters, procedure control, feed basic materials, formula and so forth.
It is viable to control the product density by altering the raw material or formula, yet it has little application worth; by changing the screw setup, the thickness control of the extruded feed item can be recognized, but the operation is troublesome. Thickness control can also be accomplished by changing the operating parameters.
Additionally, in the fish feed pellet extruder handling of water feed, in order to meet the feeding requirements of marine animals, the ups as well as downs of marine feed ought to be regulated, as well as the ups and also downs of feed are very closely pertaining to density, so density control is applied in the manufacturing of aquatic extruded feed.
Technology is especially vital. At present, controlling the density of extruded products is mainly accomplished by managing the stress and also temperature level. The major approaches are as follows:
( 1 )Open a stress relief opening on the squeezing out dental caries, and connect the pressure alleviation hole when creating floating feed, so as to meet the requirements of heat and high pressure for processing floating feed.
Open up the pressure relief hole when feeding, so that when the material gets to the pressure alleviation opening, the stress in the sleeve is partially released, and at the same time, some water vapor is additionally discharged from the stress relief opening.
These materials are extruded by fish feed pellet extruder to the end of the extruding dental caries and afterwards compressed to obtain a hefty feed with high bulk density. This stress relief opening can likewise be utilized to evacuate, to make sure that the product loses part of the water vapor during the forced motion.
This fish feed pellet extruder procedure technique understands the control of the thickness of the extruded product by controlling the stress in the squeezing out dental caries, and the result will not be impacted due to the fact that the feeding quantity does not require to be lowered.

( 2) A stress controling tool is added in the drifting fish feed extruder device (pressurization before the die). The pressure guideline of the fish feed pellet extruder is to install a shut-off valve between the extrusion tooth cavity and the discharge layout to adjust the stress difference between the extrusion tooth cavity as well as the beyond the extrusion cavity.
( 3 )Pressure cutting innovation (post-mold pressure). A brand-new kind of density control system was developed for aquafeed. This density control system of fish feed pellet extruder adopts pressurized cutting modern technology to maintain a certain favorable pressure in the cutting chamber.
When the material enters the reducing chamber from the puffing chamber, because the boiling point of water enhances with the pressure, the flash dissipation can be minimized to manage the level of growth of the product, as well as the starch particles are instantaneously strengthened in the reducing chamber, and also the product no longer gets in the regular stress from the reducing chamber.
The favorable stress of the cutting chamber can be realized by inputting compressed air with an air pump, and the follower can be shut off when discharging.
This fish feed pellet extruder process approach prevents regulating other variables that impact the level of development, therefore minimizing the need for manual operation, and at the same time, the controllability is stronger than various other methods.
Today, this brand-new fish feed pellet extruder technology has actually not been applied in China, but this modern technology transcends to the exhaust method in terms of density control of extruded products and operation and also usage, and is a brand-new direction for the development of extruded innovation.
( 4) Managing the opening price of the theme. By altering the opening rate of the discharge design template, the pressure distinction prior to and after the design template can be transformed, so regarding accomplish the purpose of managing the density of the item. The hole is obstructed.

2. Automatic control of fish feed extrusion procedure
The automated control of the fish feed pellet extruder extrusion process refers to the fast and also accurate control of the procedure criteria by equipping the extrusion tools with a computer-aided control system.
The application of automated control technology in the fish feed pellet extruder puffing procedure can not just boost job efficiency, but also improve item top quality stability. Models of automatic 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 blowing process has made fantastic development, and also a visualization control system of the puffing procedure has actually been established. The squeezing out system of fish feed pellet extruder based on FIX commercial setup software realizes the visual control of the extruding procedure
The sensing unit can be utilized to conduct on-site detection and also comments on the operating criteria of the fish feed pellet extruder, automatically change the relevant working specifications of the floating fish feed pellet maker, as well as recognize various predetermined by the driver.
Functioning parameters, with formula storage, record printing, alarm system, vibrant display screen and recording of functioning parameters. International computer automated control innovation has already been used in the field of feed handling
In the entire fish feed pellet extruder process, it has been created from a solitary computer system control system to an sophisticated automated control system, which can show shade photos in the central control space, computer program control and interaction network for floating fish feed making device operation, it can finish all production procedures without unmanned operation.
In general, the automatic control of puffing in feed handling abroad has been developing towards the direction of combining with product quality.
While the introduction of computers in my country is mostly to fix the trouble of production automation, only concentrating on the tracking of tools operation in the production process and also the control of stand-alone tools. It has actually not played its due function in boosting item top quality and also other facets.
3. Power conserving in extrusion process.
The issue of energy conserving and usage decrease is the study emphasis in the fish feed pellet extruder extrusion procedure.
Presently, it is generally via the research study of reduced power intake handling technology and the influence of major procedure specifications on energy usage, as well as the establishment of corresponding mathematical models to achieve the objective of power saving and also usage reduction.
In order to minimize the energy usage in the fish feed pellet extruder puffing process, some residential feed suppliers mainly take measures from the procedure. For instance, in the production procedure of nursing pig feed, the corn raw material used is not full puffed product, but part of the puffed material and part of the conventional material.
In the later fish feed pellet extruder granulation procedure, processes such as expansion and also reduced temperature granulation are made use of to ensure that the energy consumption each item is lowered.
From the above analysis, it can be seen that it is still a bottleneck issue exactly how the process specification research in the fish feed pellet extruder blowing procedure can be personified in reducing power consumption and also can be understood in actual production.
