In the manufacturing of extruded feed, the primary equipment is a screw fish feed pellet extruder. The material is fed right into the fish feed pellet extruder, as well as the screw screw presses the material to create an axial flow.
At the same time, as a result of the mechanical rubbing between the screw as well as the product, the material as well as the barrel, and also the product inside the material, the material is highly squeezed, stirred, and sheared, and also consequently, the material is more improved and homogenized.
As the pressure progressively raises, the temperature increases as necessary. When the paste material is expelled from the die opening, under the action of a strong pressure distinction, the product is puffed by drifting fish feed making equipment, dried out and also cooled down. The puffed product is loose, permeable, crisp, and has excellent palatability as well as flavor.

The fish feed pellet extruder blowing modern technology breaks through the typical processing technology, makes the physical properties of the feed modification qualitatively, greatly promotes the growth of the feed processing market and also the breeding industry, as well as is a significant development in the feed industry.
The fish feed pellet extruder blowing process is a process that incorporates various operations such as blending, massaging, shearing, heating, and cooling. The following is a specific analysis from the elements of thickness control, automatic control and also energy saving and also consumption decrease.
1. Thickness control innovation
In the extrusion process of fish feed pellet extruder, there are many aspects that affect the density of feed, such as processing innovation, fish feed pellet extruder tools, processing parameters, process control, feed resources, formula and more.
It is viable to regulate the product density by transforming the raw material or formula, yet it has little application worth; by transforming the screw arrangement, the density control of the extruded feed product can be realized, however the operation is inconvenient. Density control can also be attained by adjusting the operating parameters.
In addition, in the fish feed pellet extruder processing of aquatic feed, in order to meet the feeding requirements of marine animals, the ups and also downs of marine feed need to be managed, as well as the ups and downs of feed are very closely related to thickness, so density control is applied in the manufacturing of aquatic extruded feed.

Technology is especially crucial. At present, managing the density of extruded products is mainly achieved by controlling the stress as well as temperature level. The major techniques are as follows:
( 1 )Open a pressure relief hole on the extruding cavity, and connect the stress relief opening when producing drifting feed, so as to meet the demands of heat as well as high pressure for handling drifting feed.
Open up the stress relief hole when feeding, to make sure that when the material gets to the pressure alleviation opening, the pressure in the sleeve is partly released, and also at the same time, some water vapor is additionally discharged from the pressure alleviation hole.
These materials are squeezed out by fish feed pellet extruder to the end of the extruding tooth cavity and afterwards compressed to get a hefty feed with high mass thickness. This pressure relief hole can additionally be utilized to evacuate, to ensure that the material loses part of the water vapor throughout the forced movement.
This fish feed pellet extruder procedure technique understands the control of the density of the extruded product by regulating the stress in the extruding cavity, and the outcome will not be influenced due to the fact that the feeding quantity does not need to be lowered.
( 2) A stress controling device is added in the drifting fish feed extruder device (pressurization before the die). The stress regulation of the fish feed pellet extruder is to set up a shut-off shutoff between the extrusion dental caries and also the discharge theme to adjust the stress distinction in between the extrusion cavity as well as the outside of the extrusion dental caries.

( 3)Pressure reducing technology (post-mold pressure). A brand-new sort of thickness control system was developed for aquafeed. This thickness control system of fish feed pellet extruder takes on pressurized reducing modern technology to maintain a certain favorable pressure in the cutting chamber.
When the material gets in the cutting chamber from the puffing chamber, considering that the boiling point of water raises with the stress, the flash dissipation can be decreased to manage the level of development of the product, and the starch molecules are quickly solidified in the reducing chamber, and the product no longer goes into the typical stress from the cutting chamber.
The positive pressure of the reducing chamber can be understood by inputting pressed air with an air pump, and the follower can be switched off when releasing.
This fish feed pellet extruder process technique prevents controlling various other aspects that affect the level of development, therefore reducing the need for hands-on operation, as well as at the same time, the controllability is more powerful than various other approaches.
Today, this new fish feed pellet extruder modern technology has not been applied in China, but this modern technology is superior to the exhaust approach in terms of density control of extruded products as well as procedure as well as use, and is a new instructions for the growth of extruded technology.
( 4) Controlling the opening rate of the design template. By changing the opening price of the discharge design template, the pressure distinction before and also after the template can be altered, so regarding accomplish the objective of controlling 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 procedure describes the rapid and also precise control of the process criteria by gearing up the extrusion equipment with a computer-aided control system.
The application of automatic control modern technology in the fish feed pellet extruder puffing process can not only enhance work effectiveness, but likewise boost item top quality stability. Designs of automatic control in your home and also abroad
There are research studies on all sides. The automated control technology of the fish feed pellet extruder blowing procedure has made great progression, and also a visualization control system of the puffing procedure has been created. The squeezing out system of fish feed pellet extruder based on repair commercial configuration software realizes the visual control of the squeezing out process
The sensor can be used to carry out on-site detection and feedback on the operating criteria of the fish feed pellet extruder, immediately readjust the relevant working parameters of the floating fish feed pellet maker, as well as understand various pre-programmed by the operator.
Functioning parameters, with formula storage, report printing, alarm, dynamic display and recording of functioning specifications. Foreign computer system automated control innovation has already been applied in the field of feed processing
In the whole fish feed pellet extruder process, it has been created from a single computer control system to an sophisticated automatic control system, which can show shade images in the main control space, computer program control as well as communication network for floating fish feed making maker operation, it can finish all production procedures without unmanned operation.
As a whole, the automatic control of puffing in feed handling abroad has actually been developing in the direction of the instructions of combining with item high quality.
While the introduction of computer systems in my nation is generally to solve the issue of manufacturing automation, only focusing on the surveillance of devices procedure in the manufacturing process and the control of stand-alone equipment. It has not played its due role in improving item top quality and also other elements.
3. Energy conserving in extrusion process.
The problem of energy saving and also intake reduction is the research emphasis in the fish feed pellet extruder extrusion procedure.
At present, it is primarily via the research study of reduced energy usage processing innovation as well as the influence of major process criteria on power consumption, and also the establishment of matching mathematical models to accomplish the objective of energy conserving as well as consumption reduction.
In order to minimize the power intake in the fish feed pellet extruder puffing procedure, some domestic feed producers primarily take measures from the procedure. For example, in the production process of nursing pig feed, the corn resources made use of is not full puffed material, yet part of the puffed product and also part of the conventional material.
In the later fish feed pellet extruder granulation process, processes such as development and reduced temperature granulation are utilized to make certain that the energy intake per unit product is lowered.
From the above analysis, it can be seen that it is still a bottleneck problem exactly how the procedure parameter research in the fish feed pellet extruder blowing procedure can be personified in decreasing power intake and also can be understood in real production.
