Production procedure of fish feed extruder machine
With the quick development of the aquaculture sector, standard farming approaches have actually been far from meeting people's needs. The needs for tank farming fish feed made by fish feed extruder equipment are not only balanced nourishment, great security of the feed in water, no contamination to water top quality, etc, and more stringent demands are advanced for the environmental high quality of fish survival.

Today, Richi Machinery will speak about the extruded feed fish feed extruder machine. The production process normally embraces secondary squashing and also second ingredient blending, and after that travels through extrusion, drying, external spraying, cooling, squashing and also screening to complete the handling of water extruded feed.
1. Basic material cleaning and primary grinding.
There are usually two kinds of raw materials made use of in drifting fish feed factories: one is powder, which does not need to be coarsely grated. For this kind of raw material, it can directly get in the cone-shaped cleaning screen to eliminate impurities after passing through the feeding pit and lift, and after that conduct magnetic separation, and also straight get in the batching container via the representative or screw auger to participate in the very first batching;.
The material that needs to be coarsely pulverized-- granular material. This sort of material gets in the cleaning tools through the discharging pit and the elevator to go into the cleansing tools for magnetic splitting up of impurities, and then goes into the to-be-pulverized container.

For private basic materials, such as shrimp shells, they can be straight put into the silo to be crushed after magnetic splitting up without initial sieving.
Single crude pulverization is the pretreatment procedure of ultrafine pulverization in aquatic feed handling. Its major purpose is to minimize the pellet dimension difference and variation variety of materials, boost the functioning problem of the ultrafine pulverizer, as well as improve the functioning efficiency and also warranty of the ultrafine pulverizer.
The item high quality is stable; at the same time, in order to improve the working environment of employees as well as reduce cross-contamination, it is recommended to use an independent dust elimination air net, that is, an independent dirt removal system for the feeding port.
2. The first batching as well as blending.
The very first batching is mostly the prep work of public basic materials, that is, the prep work of bigger products in the formula. This fish feed extruder device process is mostly completed by electronic batching ranges.

Nonetheless, in the initial batching process, special attention should be paid to the arching issue of the batching container, which is mainly triggered by the light bulk thickness as well as poor fluidity of the raw products of the aquatic feed, particularly the top-quality water feed resources. Therefore, particular anti-arching actions must be considered the batching bin, such as the use of eccentric discharge, vibration electric motor, etc.
The single-shaft horizontal ribbon mixer can be made use of for the initial mixing, as well as the oil enhancement system must be taken into consideration on the mixer. The initial batching and also blending is also the pre-treatment procedure of ultra-fine pulverization.
This supporting devices of fish feed extruder machine is mainly to minimize the variant series of product pellet size, boost the working condition of the pulverizer, boost the functioning efficiency of the pulverizer, and also guarantee the top quality of the item.
3. Secondary crushing and also mixing of secondary ingredients.
As a result of the low food intake, short digestive system tract as well as inadequate digestive system ability of water animals, water feed requires very great crushing pellet size to boost the surface of the feed, enhance the get in touch with location in between the gastrointestinal juice of water animals and also the feed, and improve the capability of marine pets to feed the feed.

At the same time, due to the reduced consumption of aquatic pets, the mixing harmony of the feed is needed to be reflected in a smaller sized variety, which likewise requires the water feed to have a better pellet dimension.
For example, the shrimp feed ought to all travel through the 40-mesh logical sieve, and also the content on the 60-mesh sieve need to be less than 5%, so the micro-grinding procedure needs to be embraced.
In the additional pulverization procedure, the products mixed in the first time are lifted by the elevator and then go into the silo to be shattered, and after that enter the mini pulverizer. Micro-pulverizers are normally utilized in the processing of water feeds, as well as vertical-axis micro-pulverizers are normally used, which are geared up with powerful wind splitting up equipment, and after that get in the rotating grading display for testing.
The objective of setting up the rotating grading display here is generally to eliminate the great fluff created by the rugged fibers in the feed during the pulverization process, since the presence of these fine fluff is easy to follow the die opening of the fish feed extruder equipment until the die hole is obstructed, creating Shut down for cleaning, so it has to be gotten rid of.
The cleaned materials are subjected to additional batching and blending. Considering that the fineness of the products going into the additional batching mixing container is above 60 mesh and the thickness is little, unique interest must be paid to the sensation of arching.

In order to prevent this phenomenon, on the one hand, the eccentric sub-expansion receptacle can be made use of, and on the other hand, all the material discharge makers that have actually gone through ultra-fine grinding utilize an impeller feeder, which not only has an arch breaking device, but also can flexibly adjust the flow price. dimension. Numerous basic materials get in the additional mixer after additional batching.
There is an fabricated feeding port over the additional mixer, which is primarily made use of for the addition of trace ingredients. At the same time, there is a liquid addition system on the mixer for the addition of oil; one is for the addition of water. In the secondary mixing procedure, various products must be completely combined, as well as the coefficient of variation CV is less than 7%, which is the essential to guaranteeing item top quality.
For that reason, the mixer should pick a design with exceptional efficiency, such as double-shaft straight paddle mixing It has high mixing harmony, high outcome as well as rapid blending rate. After secondary squashing as well as second ingredient mixing, the product gets in the succeeding procedure-- development granulation process-- with fish feed extruder maker.
4. Extrusion process by fish feed extruder maker.
In the extrusion procedure, the material actually undertakes a cooking process under the conditions of high temperature, high humidity and also high pressure.
During this fish feed extruder device process, the physical and also chemical residential properties of the material changed highly, and also presently when the material was squeezed out from the die hole, the water in the feed was promptly converted from fluid to gaseous state and also sent out from the feed due to the fact that the stress suddenly went down from high pressure to regarding 100kPa.
Consequently, the material is squeezed out by fish feed extruder equipment to form the so-called extruded feed. Because this kind of feed not just has the advantages of general tough pellet feed - good palatability, stays clear of automatic grading of items, is simple to deliver, assists food digestion, minimizes waste in the feeding process, etc, yet also has one-of-a-kind benefits:.
In the feed, the starch has a high degree of gelatinization by fish feed extruder equipment, the healthy protein is much more digestible, as well as the application rate of the animal feed is improved; it has excellent floatability, which is very easy to observe the feeding scenario of the fish, and also can manage the water air pollution to the optimum level. These are likewise the main reasons that extruded feed is widely utilized.
There are many type of clothes dryers can be utilized after fish feed extruder maker. When the diameter of the pellets is less than 4mm, a vibrating fluidized bed dryer can be picked; when the size of the pellets is more than 4mm, a belt dryer can be chosen, or a straight float clothes dryer can be directly chosen.
Since this sort of clothes dryer can make the material in a semi-suspended state on the whole screen surface, it can not only make sure the drying effect, however additionally reduce the damage to the pellets. After the product is dried out, it enters the external spraying system.
The external spraying of the pellets is generally to meet the fish's power requirements as well as decrease the loss of heat-sensitive compounds during handling. The nutrients that should not be added in the previous procedure can be supplemented by exterior splashing, as well as at the same time, the palatability of the feed can be improved and also the powder web content can be lowered.
The optimum functioning temperature level for this procedure is around 80 ℃. After the material passes through the external spraying system, it can go into the counter-flow colder for cooling.
5. Completed item packaging.
The cooled down material is raised by the elevator and then squashed into the plane rotating display for category. The grading screen made use of after fish feed extruder machine is generally a two-layer sieve, and also the material on the lower sieve is the completed product, which can be straight entered into the finished item storehouse, and afterwards considered and packaged. The material on the upper filter requires to be gone back to the crusher for crushing. The material under the reduced filter is generally carefully smashed, which can be gone back to the batching container as waste.
The fish feed extruder equipment manufacturing process assessed above is the standard setup of the existing marine extruded feed handling technology. Using this process, sinking feed, slow sinking feed as well as drifting feed can be produced.
Although extruded fish feed extruder equipment technology has been identified by lots of manufacturers as a brand-new kind of handling modern technology, it has not been extensively made use of due to the fact that its investment is much larger than that of tough pellet feed processing technology.
However, the fish feed extruder maker puffing process is the future development trend of the feed processing industry, specifically in the application of aquatic pet feed and also animal feed, and also will certainly replace the traditional hard pellet feed processing innovation.
