.With the fast advancement of the aquaculture market, traditional farming methods have been far from fulfilling people's requirements. The demands for aquaculture fish feed made by floating fish feed making machine are not just well balanced nourishment, good security of the feed in water, no contamination to water top quality, and so on, as well as a lot more strict demands are advanced for the environmental quality of fish survival.
The feed generated by the aquaculture floating fish feed making machine is tough pellets, as well as the various other is the extruded feed pellet machine, and the refined fish feed is soft pellets.
Today, Richi Machinery will certainly discuss the extruded feed floating fish feed making machine. The production procedure typically embraces secondary crushing and also secondary active ingredient blending, and then goes through extrusion, drying, exterior splashing, cooling down, squashing as well as screening to complete the handling of aquatic extruded feed.
1. Raw material cleansing and primary grinding.
There are usually two forms of raw materials utilized in floating fish feed manufacturing facilities: one is powder, which does not need to be coarsely grated. For this sort of basic material, it can directly enter the conical cleaning screen to remove contaminations after travelling through the feeding pit as well as elevator, and after that conduct magnetic splitting up, as well as straight enter the batching container with the supplier or screw auger to participate in the first batching;.
The material that requires to be coarsely pulverized-- granular material. This type of product goes into the cleansing tools with the dumping pit and also the elevator to enter the cleaning equipment for magnetic splitting up of impurities, and then enters the to-be-pulverized bin.
For private raw materials, such as shrimp coverings, they can be directly taken into the silo to be crushed after magnetic splitting up without initial sieving.
One-time coarse pulverization is the pretreatment procedure of ultrafine pulverization in marine feed processing. Its major function is to minimize the pellet size difference and variation variety of materials, improve the working problem of the ultrafine pulverizer, and improve the working efficiency as well as guarantee of the ultrafine pulverizer.
The item top quality is steady; at the same time, in order to enhance the working environment of workers and also reduce cross-contamination, it is recommended to utilize an independent dirt removal air net, that is, an independent dirt elimination system for the feeding port.
2. The initial batching and also mixing.
The very first batching is primarily the prep work of public basic materials, that is, the prep work of bigger products in the formula. This floating fish feed making machine procedure is mainly completed by digital batching ranges.
However, in the first batching procedure, unique focus should be paid to the arching problem of the batching bin, which is generally caused by the light mass density and also poor fluidity of the raw materials of the marine feed, specifically the state-of-the-art water feed basic materials. As a result, specific anti-arching steps must be taken for the batching bin, such as the use of eccentric discharge, vibration motor, etc.
The single-shaft straight ribbon mixer can be made use of for the initial mixing, as well as the oil enhancement system must be thought about on the mixer. The very first batching and mixing is additionally the pre-treatment procedure of ultra-fine pulverization.
This complementary tools of floating fish feed making machine is mainly to reduce the variation range of product pellet dimension, enhance the working problem of the pulverizer, enhance the working efficiency of the pulverizer, and also make certain the top quality of the item.
3. Additional crushing and also blending of additional active ingredients.
Due to the reduced food consumption, short digestive tract and also bad digestive system capacity of aquatic pets, aquatic feed requires really fine squashing pellet dimension to raise the surface area of the feed, boost the call area in between the digestion juice of aquatic animals as well as the feed, as well as enhance the capability of water animals to feed the feed.
At the same time, due to the reduced intake of water pets, the blending harmony of the feed is required to be mirrored in a smaller sized range, which also needs the water feed to have a finer pellet dimension.
As an example, the shrimp feed need to all go through the 40-mesh analytical sieve, and the material on the 60-mesh sieve ought to be less than 5%, so the micro-grinding process must be taken on.
In the second pulverization procedure, the products mixed in the first time are raised by the elevator and afterwards get in the silo to be crushed, and afterwards go into the micro pulverizer. Micro-pulverizers are typically utilized in the handling of marine feeds, and vertical-axis micro-pulverizers are usually used, which are outfitted with powerful wind separation devices, and afterwards go into the rotating grading display for screening.
The function of setting up the rotary grading screen below is mostly to remove the fine fluff developed by the coarse fibers in the feed during the pulverization process, due to the fact that the presence of these great fluff is easy to adhere to the die hole of the floating fish feed making machine till the die hole is blocked, causing Close down for cleaning, so it needs to be eliminated.
The cleaned up products go through additional batching as well as mixing. Considering that the excellence of the materials getting in the second batching mixing container is above 60 mesh and also the density is small, unique interest ought to be paid to the phenomenon of arching.
In order to avoid this phenomenon, on the one hand, the eccentric sub-expansion hopper can be used, and also on the other hand, all the material discharge machines that have actually undertaken ultra-fine grinding use an impeller feeder, which not just has an arch splitting device, but likewise can flexibly readjust the circulation rate. size. Various raw materials go into the second mixer after secondary batching.
There is a man-made feeding port above the secondary mixer, which is generally made use of for the enhancement of trace ingredients. At the same time, there is a fluid addition system on the mixer for the addition of grease; one is for the addition of water. In the additional blending process, various products need to be completely mixed, as well as the coefficient of variant CV is less than 7%, which is the essential to making certain product quality.
As a result, the mixer should choose a model with exceptional performance, such as double-shaft straight paddle mixing It has high mixing uniformity, high output and fast mixing speed. After additional squashing as well as secondary ingredient mixing, the product gets in the subsequent procedure-- development granulation process-- with floating fish feed making machine.
4. Extrusion process by floating fish feed making machine.
In the extrusion process, the product really undergoes a cooking process under the problems of high temperature, high humidity as well as high pressure.
During this floating fish feed making machine process, the physical and also chemical buildings of the product transformed strongly, as well as presently when the product was extruded from the die hole, the water in the feed was instantly transformed from liquid to gaseous state and sent out from the feed because the stress all of a sudden dropped from high pressure to concerning 100kPa.
Thereby, the product is squeezed out by floating fish feed making machine to form the supposed extruded feed. Because this type of feed not only has the advantages of basic difficult pellet feed - great palatability, stays clear of automated grading of items, is simple to move, helps food digestion, minimizes waste in the feeding procedure, etc, however also has unique advantages:.
In the feed, the starch has a high degree of gelatinization by floating fish feed making machine, the protein is a lot more absorbable, and also the use price of the pet feed is boosted; it has superb floatability, which is very easy to observe the feeding circumstance of the fish, and also can control the water contamination to the maximum extent. These are additionally the primary reasons extruded feed is commonly used.
There are several kinds of clothes dryers can be used after floating fish feed making machine. When the size of the pellets is less than 4mm, a shaking fluidized bed dryer can be picked; when the size of the pellets is above 4mm, a belt dryer can be picked, or a horizontal float clothes dryer can be directly selected.
Since this type of clothes dryer can make the material in a semi-suspended state on the entire screen surface, it can not just guarantee the drying result, however also reduce the damage to the pellets. After the product is dried, it gets in the outside splashing system.
The exterior spraying of the pellets is generally to fulfill the fish's energy requirements and decrease the loss of heat-sensitive materials during processing. The nutrients that should not be included the previous process can be supplemented by exterior splashing, and at the same time, the palatability of the feed can be boosted and also the powder material can be reduced.
The optimum working temperature level for this process is around 80 ℃. After official source goes through the external spraying system, it can enter the counter-flow cooler for air conditioning.
5. Finished product packaging.
The cooled product is lifted by the lift and afterwards crushed right into the aircraft rotating screen for classification. The rating filter utilized after floating fish feed making machine is generally a two-layer sieve, as well as the product on the reduced filter is the ended up product, which can be directly participated in the completed product storehouse, and after that evaluated as well as packaged. The material on the top screen needs to be returned to the crusher for crushing. The product under the lower screen is typically carefully smashed, which can be gone back to the batching bin as waste.
The floating fish feed making machine production procedure examined above is the traditional setup of the existing aquatic extruded feed handling modern technology. Using this process, sinking feed, slow-moving sinking feed and also floating feed can be produced.
Although extruded floating fish feed making machine modern technology has actually been identified by many makers as a new sort of handling technology, it has actually not been extensively utilized because its investment is much larger than that of tough pellet feed processing technology.
However, the floating fish feed making machine puffing procedure is the future development fad of the feed handling industry, specifically in the application of aquatic pet feed as well as pet feed, and also will most definitely replace the typical hard pellet feed processing technology.
