Drifting fish feed pellet extruder modern technology
In the manufacturing of extruded feed, the major equipment is a screw fish feed pellet extruder. The material is fed into the fish feed pellet extruder, as well as the screw screw presses the product to create an axial flow.
At the same time, as a result of the mechanical friction in between the screw and also the material, the product and also the barrel, as well as the product inside the material, the material is strongly squeezed, stirred, as well as sheared, and also as a result, the material is further refined and homogenized.
As the stress progressively raises, the temperature raises appropriately. When the paste material is expelled from the die hole, under the action of a strong stress distinction, the product is puffed by drifting fish feed making device, dried out and also cooled. The puffed item hangs, permeable, crisp, and has excellent palatability and also taste.
The fish feed pellet extruder puffing technology appear the conventional handling technology, makes the physical homes of the feed modification qualitatively, significantly promotes the growth of the feed processing market and the reproducing industry, as well as is a significant innovation in the feed industry.

The fish feed pellet extruder puffing procedure is a procedure that incorporates different procedures such as mixing, working, shearing, heating, and air conditioning. The following is a specific analysis from the elements of thickness control, automated control as well as energy saving and also usage reduction.
1. Density control innovation
In the extrusion procedure of fish feed pellet extruder, there are several variables that impact the thickness of feed, such as refining technology, fish feed pellet extruder equipment, refining parameters, procedure control, feed resources, formula and so on.
It is feasible to regulate the item thickness by transforming the raw product or formula, however it has little application value; by changing the screw setup, the density control of the extruded feed product can be understood, however the operation is bothersome. Thickness control can likewise be attained by readjusting the operating specifications.
In addition, in the fish feed pellet extruder handling of water feed, in order to fulfill the feeding requirements of water pets, the ups and also downs of water feed need to be controlled, and the ups and downs of feed are very closely pertaining to density, so density control is applied in the manufacturing of water extruded feed.
Technology is particularly vital. Currently, managing the thickness of extruded products is generally achieved by managing the pressure as well as temperature. The major techniques are as adheres to:
( 1 ) Open up a stress alleviation hole on the squeezing out cavity, and plug the stress relief hole when generating drifting feed, so as to fulfill the requirements of heat and also high pressure for handling drifting feed.

Open the pressure relief hole when feeding, so that when the product reaches the pressure relief opening, the pressure in the sleeve is partially launched, as well as at the same time, some water vapor is likewise released from the stress relief opening.
These materials are squeezed out by fish feed pellet extruder throughout of the extruding dental caries and then compressed to acquire a heavy feed with high bulk density. This stress alleviation hole can additionally be utilized to leave, to ensure that the material loses part of the water vapor throughout the forced activity.
This fish feed pellet extruder procedure method understands the control of the density of the extruded product by managing the pressure in the extruding cavity, and the result will not be affected because the feeding quantity does not need to be minimized.
( 2) A pressure controling device is added in the drifting fish feed extruder device (pressurization before the die). The stress law of the fish feed pellet extruder is to mount a shut-off shutoff in between the extrusion cavity as well as the discharge theme to change the stress difference in between the extrusion cavity and also the outside of the extrusion dental caries.
( 3 ) Stress cutting modern technology (post-mold stress). A new kind of density control system was created for aquafeed. This thickness control system of fish feed pellet extruder takes on pressurized reducing technology to keep a specific favorable stress in the cutting chamber.
When the product enters the reducing chamber from the puffing chamber, considering that the boiling point of water raises with the pressure, the flash evaporation can be reduced to manage the level of expansion of the material, and also the starch particles are immediately strengthened in the reducing chamber, and also the material no more goes into the typical stress from the reducing chamber.
The positive pressure of the reducing chamber can be understood by inputting pressed air with an air pump, as well as the follower can be shut off when discharging.

This fish feed pellet extruder process method stays clear of controlling other factors that affect the degree of development, consequently reducing the demand for manual operation, as well as at the same time, the controllability is more powerful than various other approaches.
At present, this brand-new fish feed pellet extruder modern technology has actually not been used in China, yet this innovation transcends to the exhaust technique in terms of thickness control of extruded products as well as procedure as well as usage, and also is a new instructions for the growth of extruded innovation.
( 4) Controlling the opening rate of the theme. By transforming the opening rate of the discharge theme, the pressure difference before as well as after the template can be transformed, so regarding achieve the objective of regulating the thickness of the product. The hole is blocked.
2. Automatic control of fish feed extrusion procedure
The automated control of the fish feed pellet extruder extrusion process refers to the fast as well as exact control of the procedure criteria by outfitting 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 improve job efficiency, yet additionally boost item quality stability. Designs of automated control in the house as well as abroad
There are studies on all sides. The automated control modern technology of the fish feed pellet extruder blowing procedure has actually made excellent progression, and a visualization control system of the puffing procedure has been created. The squeezing out system of fish feed pellet extruder based on FIX industrial arrangement software understands the visual control of the squeezing out process
The sensing unit can be used to conduct on-site discovery as well as feedback on the operating criteria of the fish feed pellet extruder, instantly adjust the pertinent functioning specifications of the floating fish feed pellet device, as well as realize different pre-programmed by the driver.
Working criteria, with formula storage, report printing, alarm system, dynamic screen and also recording of working specifications. Foreign computer automatic control technology has currently been used 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 pictures in the main control room, computer system program control as well as communication network for drifting fish feed making maker operation, it can complete all production treatments without unmanned operation.
In general, the automatic control of blowing in feed handling abroad has been creating towards the direction of integrating with item top quality.
While the intro of computers in my nation is primarily to resolve the trouble of production automation, only focusing on the monitoring of devices operation in the manufacturing procedure and also the control of stand-alone equipment. It has not played its due role in improving product high quality and various other elements.
3. Power saving in extrusion process.
The trouble of power conserving and usage decrease is the study focus in the fish feed pellet extruder extrusion procedure.
Today, it is mainly with the research study of low power intake handling innovation as well as the influence of main process criteria on power consumption, and the establishment of matching mathematical models to attain the function of power saving as well as intake decrease.
In order to minimize the energy consumption in the fish feed pellet extruder puffing procedure, some domestic feed producers primarily take measures from the procedure. For instance, in the manufacturing procedure of suckling pig feed, the corn basic material utilized is not complete puffed material, yet part of the puffed product as well as part of the traditional product.
In the later fish feed pellet extruder granulation procedure, processes such as development as well as low temperature level granulation are used to guarantee that the energy intake each item is lowered.
From the above evaluation, it can be seen that it is still a traffic jam problem exactly how the procedure parameter study in the fish feed pellet extruder blowing procedure can be symbolized in lowering power intake and can be understood in actual production.
