Although the application of floating fish feed extruder extrusion technology in the feed market began late, the development speed is very quick, and also the application range is also fairly vast, and also it has even end up being a crucial technological means in the current feed processing.
Nevertheless, exactly how to make use of the extrusion innovation as well as floating fish feed pellet making machine scientifically, reasonably, as well as stably for a long time to optimize its advantages as well as functions is still a technological issue that problems many feed business.
- The impact of floating feed extruder machine
( 1) Influence of extrusion on starch
The starch in the feed is mainly amylose, as well as because the starch pellets create granular agglomerates, its structure is small and also the water absorption is poor. The starch enters the extruder from the floating fish feed making machine conditioner, and in the shut atmosphere of high temperature and also high pressure, the macromolecular polymer remains in a molten state, and the neighborhood molecular chain is cut off by strong stress and also shearing pressure, causing the degradation of amylopectin.
At the same time, it additionally causes the cleavage of the α-1,4 glycosidic bond in the amylose, leading to starch dextrinization, and also the starch molecules are broken into short-chain dextrins, which are weakened right into soluble reducing sugars, which enhance the solubility, digestibility as well as taste of starch.
The extruded starch made by floating fish feed pellet making machine, not just has gelatinization result, but additionally saccharification impact, which increases the water-soluble material of starch numerous times to dozens of times, provides favorable conditions for the activity of enzymes, and boosts the usage rate of starch in marine feed.
( 2) The effect of extrusion on healthy protein
Throughout the floating fish feed pellet making machine extrusion process, the protein goes through high temperature, high pressure and strong mechanical shearing force in the extrusion tooth cavity, its surface fee is redistributed and also has a tendency to be consistent, the molecular structure is stretched and rearranged, and the intermolecular hydrogen bonds,
Secondary bonds such as disulfide bonds are partly damaged, leading to the final denaturation of the healthy protein. This denaturation makes it less complicated for proteases to get in the inside of the healthy protein, thus boosting digestibility.
In the floating fish feed pellet making machine extrusion procedure, the major factors influencing protein denaturation are temperature, stress, strong shear and also the wetness of the extruded material.
( 3) The effect of extrusion on fat
The inactivation of lipase and also lipoxygenase in the feed improves the storage space security of fat, and also promotes the development of fat-starch facilities and also decreases fat wear and tear, which is advantageous for fat storage space.
Full-fat soybeans are blown to decrease the opportunity of fat being revealed to air as well as weaken. In a high-shear environment, soybean oil cells are completely ruptured, thus enhancing the usage of fat. Under light problems, such as the floating fish feed pellet making machine blowing temperature level listed below 100 ℃, the result of fat oxidation is small.
As the floating fish feed making machine puffing temperature level climbs from 120 ℃ to 170 ℃, the dampness raises, and the recurring time in the extrusion cavity increases, as well as the fat oxidation value enhances rapidly.
On top of that, there are other aspects impacting the oxidation of fat, such as the boost of item surface area as well as change steel components can accelerate the oxidation of fat.
( 4) Impact of extrusion on unrefined fiber
Unrefined fiber feed, also referred to as harsh feed, describes feed with a natural wetness material below 60% as well as a crude fiber content equal to or more than 18% in dry issue. The crude fiber content in all kinds of straws is more than 20%, as well as the unrefined fiber content in rice husk is 44%, which is the grain byproduct with the highest possible unrefined fiber web content in all feeds.
The annual result of numerous sorts of straw in my country is 5 trillion tons, and the part made use of for feed is less than 10%. Compared to the use rate of 20% in established countries, there is a big void.
Through the floating fish feed pellet making machine extrusion technology, as a result of the humidification, heating, pressurization and expansion, the lignin in between cells as well as the layers in the cell wall surface is melted, some hydrogen bonds are damaged, the crystallinity is reduced, and the macromolecular compounds are decayed.
The initial compact structure becomes fluffy as well as part of the absorbable compounds are released, therefore boosting the application price of the feed. The present research study outcomes reveal that after the fibers are refined and also squeezed out, the web content of soluble fibers boosts reasonably, usually by regarding 3%.
The fiber change is generally impacted by the floating fish feed pellet making machine handling problems, and apparent modifications will certainly occur when the processing conditions are serious.
( 5) Influence of extrusion on vitamin.
The heat, high humidity as well as high pressure of the floating fish feed pellet making machine puffing procedure will result in the loss of the biological task of various vitamins, amongst which the vitamins that are conveniently oxidized are specifically obvious.
The vitamins added or contributed to the feed are all lost as a result of extrusion processing of floating fish feed extruder. The way to conquer the loss of vitamin task caused by puffing is to boost the quantity of vitamins added to the formula, to make sure that the shed recurring vitamins can still satisfy the demands of pets.
( 6) The impact of extrusion on unsafe substances
The extrusion process of floating fish feed pellet making machine can not only efficiently lower the anti-nutritional factors in the feed such as antitrypsin, lipoxygenase, aringoxin, and so on, however also disintegrate the mustard II and Gossypol, lowering the material of its dangerous components.
Additionally, for typical hazardous microbes in feed raw materials, such as Escherichia coli, Salmonella, and so on, the majority of the harmful microorganisms can be eliminated by extrusion.
