In addition, in the fish feed pellet extruder processing of marine feed, in order to fulfill the feeding demands of marine animals, the ups as well as downs of marine feed need to be managed, and the ups and downs of feed are closely pertaining to thickness, so thickness control is applied in the production of marine extruded feed.
Modern technology is specifically essential. Currently, controlling the density of extruded products is mostly achieved by controlling the pressure and temperature. The primary approaches are as adheres to:
( 1 )Open a stress relief hole on the squeezing out dental caries, and plug the pressure relief opening when creating floating feed, so regarding satisfy the demands of high temperature and also high pressure for handling drifting feed.

Open up the pressure relief hole when feeding, to make sure that when the material reaches the pressure relief opening, the stress in the sleeve is partly released, as well as at the same time, some water vapor is likewise released from the pressure relief hole.
These products are extruded by fish feed pellet extruder to the end of the extruding dental caries and after that compressed to obtain a hefty feed with high mass density. This pressure relief opening can also be utilized to evacuate, to ensure that the material sheds part of the water vapor during the forced activity.
This fish feed pellet extruder procedure method realizes the control of the thickness of the extruded product by controlling the stress in the extruding cavity, as well as the result will certainly not be affected due to the fact that the feeding amount does not require to be decreased.

( 2) A pressure regulating device is added in the floating fish feed extruder equipment (pressurization prior to the die). The stress regulation 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 layout to change the pressure difference between the extrusion tooth cavity and the beyond the extrusion tooth cavity.
( 2 )Pressure reducing innovation (post-mold stress). A new kind of density control system was developed for aquafeed. This thickness control system of fish feed pellet extruder embraces pressurized reducing innovation to maintain a specific favorable pressure in the cutting chamber.
When the product gets in the reducing chamber from the puffing chamber, given that the boiling point of water enhances with the stress, the flash evaporation can be lowered to control the degree of growth of the product, and also the starch particles are instantaneously solidified in the cutting chamber, and also the product no longer goes into the regular pressure from the cutting chamber.
The positive 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 process method stays clear of regulating other factors that affect the degree of development, thereby lowering the requirement for hand-operated procedure, as well as at the same time, the controllability is stronger than various other approaches.
Today, this brand-new fish feed pellet extruder modern technology has not been applied in China, but this technology transcends to the exhaust method in terms of density control of extruded items as well as operation and use, and is a new direction for the growth of extruded technology.
( 4) Regulating the opening price of the theme. By altering the opening price of the discharge theme, the stress difference before and after the design template can be transformed, so as to accomplish the objective of regulating the thickness 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 describes the quick and accurate control of the process specifications by outfitting 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 efficiency, yet likewise boost product high quality stability. Versions of automatic control in your home as well as abroad
There are research studies on all sides. The automated control technology of the fish feed pellet extruder puffing procedure has made wonderful progression, and a visualization control system of the puffing procedure has been created. The extruding system of fish feed pellet extruder based upon solution industrial configuration software program realizes the visual control of the extruding process
The sensing unit can be made use of to carry out on-site detection and also feedback on the operating parameters of the fish feed pellet extruder, instantly adjust the appropriate functioning specifications of the floating fish feed pellet equipment, as well as understand various pre-programmed by the driver.
Functioning specifications, with formula storage, report printing, alarm system, dynamic display screen and recording of working specifications. International computer system automatic control innovation has already been applied in the field of feed processing
In the whole fish feed pellet extruder procedure, it has been created from a solitary computer control system to an sophisticated automated control system, which can show shade pictures in the main control space, computer program control and also communication network for drifting fish feed making maker procedure, it can finish all manufacturing treatments without unmanned operation.
Generally, the automated control of puffing in feed processing abroad has actually been developing in the direction of the direction of incorporating with item quality.
While the intro of computer systems in my country is primarily to resolve the problem of production automation, only concentrating on the surveillance of equipment procedure in the production process and the control of stand-alone tools. It has not played its due role in boosting item top quality and other elements.
3. Energy conserving in extrusion procedure.
The issue of power conserving and also intake decrease is the study emphasis in the fish feed pellet extruder extrusion process.
Today, it is mostly with the research of reduced power usage processing innovation as well as the impact of main procedure parameters on energy consumption, and also the establishment of matching mathematical designs to attain the objective of energy conserving as well as consumption reduction.
In order to minimize the energy consumption in the fish feed pellet extruder blowing process, some residential feed producers mostly take measures from the procedure. For instance, in the production process of suckling pig feed, the corn raw material used is not full puffed material, but part of the puffed material as well as part of the traditional material.
In the later fish feed pellet extruder granulation process, procedures such as expansion and reduced temperature granulation are made use of to make sure that the power consumption per unit item is minimized.
From the above evaluation, it can be seen that it is still a traffic jam issue just how the procedure parameter research in the fish feed pellet extruder blowing procedure can be symbolized in minimizing power intake and also can be realized in real manufacturing.
