In addition, in the fish feed pellet extruder processing of aquatic feed, in order to satisfy the feeding requirements of water animals, the ups as well as downs of aquatic feed must be controlled, and also the ups and downs of feed are closely related to thickness, so density control is used in the manufacturing of marine extruded feed.
Innovation is specifically vital. Presently, controlling the thickness of extruded items is mainly achieved by regulating the pressure and temperature. The main approaches are as adheres to:
( 1 )Open a stress alleviation opening on the squeezing out tooth cavity, and connect the pressure alleviation opening when creating drifting feed, so regarding satisfy the requirements of high temperature and also high pressure for handling floating feed.
Open the stress alleviation hole when feeding, to ensure that when the material gets to the pressure alleviation opening, the pressure in the sleeve is partially released, and at the same time, some water vapor is likewise discharged from the pressure alleviation hole.

These products are squeezed out by fish feed pellet extruder to the end of the extruding dental caries 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 material loses part of the water vapor throughout the forced motion.
This fish feed pellet extruder procedure technique understands the control of the density of the extruded item by controlling the stress in the extruding tooth cavity, and also the output will not be influenced since the feeding quantity does not need to be lowered.
( 2) A stress controling gadget is added in the floating fish feed extruder equipment (pressurization prior to the die). The pressure law of the fish feed pellet extruder is to install a shut-off shutoff between the extrusion tooth cavity as well as the discharge layout to change the pressure distinction in between the extrusion cavity as well as the outside of the extrusion dental caries.

( 2 )Pressure reducing innovation (post-mold pressure). A brand-new sort of thickness control system was developed for aquafeed. This density control system of fish feed pellet extruder embraces pressurized reducing modern technology to preserve a certain favorable stress in the cutting chamber.
When the material goes into the reducing chamber from the puffing chamber, because the boiling point of water boosts with the pressure, the flash dissipation can be minimized to manage the level of growth of the product, and also the starch molecules are quickly solidified in the cutting chamber, and also the material no longer gets in the normal stress from the cutting chamber.
The positive pressure of the cutting chamber can be understood by inputting compressed air with an air pump, as well as the fan can be switched off when discharging.
This fish feed pellet extruder procedure technique stays clear of controlling other factors that affect the level of development, consequently minimizing the demand for manual procedure, and at the same time, the controllability is more powerful than other methods.
Today, this new fish feed pellet extruder technology has not been used in China, but this innovation is superior to the exhaust technique in terms of thickness control of extruded items and operation and also use, and is a new instructions for the advancement of extruded modern technology.
( 4) Regulating the opening rate of the template. By transforming the opening rate of the discharge template, the stress distinction before and after the design template can be transformed, so regarding achieve the objective of managing the thickness of the product. The hole is obstructed.
2. Automatic control of fish feed extrusion process
The automatic control of the fish feed pellet extruder extrusion process describes the quick and accurate control of the process specifications by equipping the extrusion devices with a computer-aided control system.
The application of automated control modern technology in the fish feed pellet extruder puffing process can not just improve work effectiveness, but also enhance product top quality security. Versions of automated control in the house and also abroad
There are research studies on all sides. The automatic control technology of the fish feed pellet extruder puffing process has actually made great progression, and also a visualization control system of the puffing process has actually been developed. The squeezing out system of fish feed pellet extruder based upon repair industrial configuration software program recognizes the aesthetic control of the squeezing out procedure
The sensor can be made use of to perform on-site discovery and also responses on the operating criteria of the fish feed pellet extruder, immediately readjust the appropriate working criteria of the drifting fish feed pellet machine, as well as understand numerous pre-programmed by the operator.
Functioning parameters, with formula storage space, report printing, alarm system, dynamic screen as well as recording of working parameters. Foreign computer automated control modern technology has currently been applied in the field of feed handling
In the whole fish feed pellet extruder process, it has been developed from a single computer system control system to an advanced automatic control system, which can show color pictures in the main control area, computer system program control and interaction network for drifting fish feed making machine procedure, it can complete all manufacturing treatments without unmanned procedure.
Generally, the automated control of puffing in feed handling abroad has actually been developing towards the direction of integrating with product top quality.
While the intro of computers in my country is primarily to address the trouble of manufacturing automation, only concentrating on the monitoring of equipment operation in the manufacturing process as well as the control of stand-alone devices. It has actually not played its due role in improving product high quality and various other aspects.
3. Power saving in extrusion procedure.
The problem of power conserving as well as intake reduction is the research focus in the fish feed pellet extruder extrusion procedure.
Currently, it is generally through the research study of reduced energy intake processing modern technology and also the influence of primary procedure criteria on energy consumption, as well as the establishment of matching mathematical designs to achieve the function of energy conserving and also usage decrease.
In order to decrease the power consumption in the fish feed pellet extruder puffing procedure, some domestic feed suppliers mainly take measures from the process. For instance, in the production procedure of suckling pig feed, the corn resources made use of is not full puffed material, however part of the puffed product as well as part of the traditional product.
In the later fish feed pellet extruder granulation process, procedures such as expansion and reduced temperature level granulation are made use of to make certain that the energy usage each product is minimized.
From the above evaluation, it can be seen that it is still a traffic jam trouble just how the process criterion research study in the fish feed pellet extruder puffing process can be symbolized in decreasing power usage and can be understood in actual manufacturing.
