Today, Richi Equipment will certainly speak about the extruded feed fish feed extruder equipment. The production process generally embraces additional crushing and additional ingredient mixing, and then passes through extrusion, drying out, exterior splashing, cooling, crushing and screening to finish the processing of marine extruded feed.
1. Basic material cleansing and primary grinding.
There are generally 2 kinds of raw materials made use of in drifting fish feed manufacturing facilities: one is powder, which does not require to be coarsely pulverized. For this sort of resources, it can straight get in the conical cleansing screen to get rid of contaminations after going through the feeding pit and also lift, and then conduct magnetic splitting up, and also directly enter the batching bin with the supplier or screw auger to participate in the initial batching;.
The product that requires to be coarsely shattered-- granular material. This type of material enters the cleaning equipment via the unloading pit and the elevator to get in the cleaning devices for magnetic splitting up of impurities, and then gets in the to-be-pulverized container.

For individual raw materials, such as shrimp coverings, they can be directly taken into the silo to be squashed after magnetic splitting up without preliminary sieving.
Single coarse pulverization is the pretreatment procedure of ultrafine pulverization in marine feed handling. Its major objective is to minimize the pellet dimension difference and variant variety of materials, improve the working problem of the ultrafine pulverizer, and also improve the working effectiveness and assurance of the ultrafine pulverizer.
The product high quality is stable; at the same time, in order to enhance the workplace of employees as well as reduce cross-contamination, it is recommended to make use of an independent dust elimination air internet, that is, an independent dust elimination system for the feeding port.
2. The very first batching and blending.
The initial batching is primarily the prep work of public basic materials, that is, the prep work of larger products in the formula. This fish feed extruder equipment process is generally finished by digital batching scales.
Nevertheless, in the first batching procedure, unique focus needs to be paid to the arching trouble of the batching bin, which is generally brought on by the light mass thickness and inadequate fluidness of the raw products of the water feed, particularly the top-quality marine feed basic materials. Therefore, certain anti-arching procedures should be taken for the batching container, such as the use of eccentric discharge, vibration motor, etc.
The single-shaft horizontal bow mixer can be used for the initial mixing, and also the grease addition system have to be thought about on the mixer. The first batching and also blending is additionally the pre-treatment procedure of ultra-fine pulverization.
This complementary equipment of fish feed extruder device is mostly to decrease the variant range of product pellet size, improve the functioning problem of the pulverizer, enhance the functioning effectiveness of the pulverizer, and also make sure the quality of the product.

3. Secondary squashing as well as blending of secondary active ingredients.
As a result of the low food intake, short digestive system system and also poor digestion capability of marine pets, aquatic feed requires very great squashing pellet size to raise the surface area of the feed, enhance the get in touch with location in between the digestive juice of water animals as well as the feed, and enhance the ability of marine pets to feed the feed.
At the same time, as a result of the reduced consumption of marine animals, the blending uniformity of the feed is needed to be mirrored in a smaller sized variety, which likewise needs the marine feed to have a finer pellet size.
For instance, the shrimp feed need to all pass through the 40-mesh logical sieve, as well as the content on the 60-mesh filter ought to be less than 5%, so the micro-grinding procedure should be adopted.
In the secondary pulverization procedure, the products mixed in the very first time are raised by the lift and afterwards go into the silo to be pulverized, and afterwards enter the mini pulverizer. Micro-pulverizers are typically made use of in the handling of aquatic feeds, as well as vertical-axis micro-pulverizers are generally utilized, which are outfitted with effective wind splitting up equipment, and afterwards go into the rotating grading screen for testing.
The purpose of setting up the rotating grading display here is mainly to eliminate the great fluff developed by the rugged fibers in the feed throughout the pulverization procedure, due to the fact that the existence of these fine fluff is simple to follow the die opening of the fish feed extruder maker till the die opening is obstructed, causing Shut down for cleansing, so it needs to be eliminated.

The cleansed products are subjected to secondary batching as well as blending. Because the fineness of the materials getting in the secondary batching mixing container is above 60 mesh and also the density is tiny, special attention ought to be paid to the sensation of arching.
In order to stop this phenomenon, on the one hand, the eccentric sub-expansion hopper can be made use of, and also on the other hand, all the material discharge devices that have actually gone through ultra-fine grinding make use of an impeller feeder, which not only has an arch splitting device, however likewise can flexibly readjust the circulation price. dimension. Various raw materials enter the secondary mixer after additional batching.
There is an man-made feeding port over the second mixer, which is generally used for the addition of trace ingredients. At the same time, there is a liquid addition system on the mixer for the enhancement of grease; one is for the enhancement of water. In the secondary blending process, numerous products need to be fully combined, and the coefficient of variant curriculum vitae is less than 7%, which is the vital to ensuring item quality.
For that reason, the mixer has to pick a model with exceptional performance, such as double-shaft straight paddle blending It has high mixing harmony, high result as well as rapid blending rate. After second squashing and also additional component blending, the material goes into the subsequent process-- growth granulation procedure-- with fish feed extruder device.
4. Extrusion procedure by fish feed extruder device.
In the extrusion procedure, the material in fact undertakes a cooking procedure under the problems of heat, high humidity and also high pressure.
During this fish feed extruder device procedure, the physical and also chemical residential or commercial properties of the product altered highly, as well as at the moment when the material was extruded from the die opening, the water in the feed was immediately transformed from fluid to aeriform state and also emitted from the feed due to the fact that the stress unexpectedly dropped from high pressure to about 100kPa.
Thereby, the product is squeezed out by fish feed extruder device to develop the so-called extruded feed. Due to the fact that this sort of feed not only has the advantages of general tough pellet feed - excellent palatability, avoids automated grading of items, is simple to transport, helps digestion, minimizes waste in the feeding process, etc, yet also has special benefits:.
In the feed, the starch has a high level of gelatinization by fish feed extruder machine, the protein is extra digestible, and also the usage price of the pet feed is enhanced; it has excellent floatability, which is very easy to observe the feeding situation of the fish, and also can manage the water air pollution to the optimum extent. These are additionally the primary reasons why extruded feed is widely made use of.

There are several type of clothes dryers can be used after fish feed extruder equipment. When the diameter of the pellets is less than 4mm, a shaking fluidized bed clothes dryer can be picked; when the size of the pellets is higher than 4mm, a belt dryer can be picked, or a straight float clothes dryer can be straight chosen.
Because this type of dryer can make the product in a semi-suspended state on the entire display surface, it can not just make certain the drying out effect, but likewise decrease the damage to the pellets. After the material is dried, it gets in the outside spraying system.
The exterior splashing of the pellets is generally to satisfy the fish's energy demands and minimize the loss of heat-sensitive materials throughout processing. The nutrients that need to not be added in the previous procedure can be supplemented by outside spraying, and also at the same time, the palatability of the feed can be improved and also the powder material can be decreased.
The maximum working temperature level for this procedure is around 80 ℃. After the material goes through the external spraying system, it can go into the counter-flow cooler for air conditioning.
5. Completed product packaging.
The cooled down product is lifted by the lift and then squashed right into the aircraft rotary display for category. The rating filter made use of after fish feed extruder machine is typically a two-layer screen, and the material on the lower screen is the ended up product, which can be straight entered into the completed item storehouse, and afterwards evaluated as well as packaged. The product on the top filter requires to be gone back to the crusher for squashing. The product under the reduced sieve is normally finely smashed, which can be gone back to the batching container as waste.
The fish feed extruder maker production procedure examined above is the traditional configuration of the current water extruded feed handling modern technology. Using this procedure, sinking feed, sluggish sinking feed as well as floating feed can be produced.
Although extruded fish feed extruder maker innovation has been acknowledged by numerous makers as a new type of handling innovation, it has actually not been extensively used since its financial investment is a lot larger than that of tough pellet feed processing modern technology.
Nonetheless, the fish feed extruder maker blowing procedure is the future advancement trend of the feed handling market, especially in the application of aquatic animal feed and pet dog feed, as well as will absolutely change the typical hard pellet feed processing innovation.
