Today, Richi Machinery will certainly speak about the extruded feed fish feed extruder maker. The production procedure typically adopts second crushing and secondary component mixing, and after that passes through extrusion, drying out, outside splashing, cooling down, crushing and also screening to complete the processing of aquatic ...
... extruded feed.

1. Resources cleansing and key grinding.

There are typically 2 forms of basic materials used in floating fish feed factories: one is powder, which does not require to be coarsely pulverized. For this type of raw material, it can directly go into the conical cleansing display to remove pollutants after travelling through the feeding pit and lift, and afterwards conduct magnetic separation, as well as straight enter the batching bin through the representative or screw auger to take part in the first batching;

The product that needs to be coarsely shattered-- granular product. This kind of material goes into the cleaning devices with the dumping pit and the lift to go into the cleansing equipment for magnetic splitting up of pollutants, and afterwards goes into the to-be-pulverized bin.

For individual resources, such as shrimp shells, they can be straight taken into the silo to be crushed after magnetic splitting up without preliminary sieving.

Single coarse pulverization is the pretreatment process of ultrafine pulverization in water feed processing. Its primary objective is to decrease the pellet size difference as well as variation range of materials, boost the functioning problem of the ultrafine pulverizer, and enhance the working effectiveness as well as assurance of the ultrafine pulverizer.

The product quality is steady; at the same time, in order to enhance the working environment of employees and also minimize cross-contamination, it is suggested to make use of an independent dirt elimination air internet, that is, an independent dust elimination system for the feeding port.

2. The initial batching and mixing.

The first batching is mostly the prep work of public raw materials, that is, the preparation of bigger materials in the formula. This fish feed extruder maker process is generally completed by digital batching scales.

However, in the initial batching procedure, special interest needs to be paid to the arching problem of the batching bin, which is mainly caused by the light bulk thickness and inadequate fluidity of the raw products of the water feed, particularly the state-of-the-art aquatic feed resources. For that reason, particular anti-arching steps need to be considered the batching container, such as the use of eccentric discharge, vibration motor, etc.

The single-shaft straight ribbon mixer can be utilized for the very first mixing, as well as the oil enhancement system must be taken into consideration on the mixer. The very first batching and also blending is additionally the pre-treatment procedure of ultra-fine pulverization.

This supporting equipment of fish feed extruder device is mostly to reduce the variation variety of product pellet dimension, boost the working condition of the pulverizer, boost the working performance of the pulverizer, and also ensure the high quality of the product.

3. Secondary squashing and mixing of secondary components.

Because of the low food consumption, brief digestive system system and poor gastrointestinal capability of marine animals, marine feed requires extremely great crushing pellet dimension to raise the area of the feed, enhance the get in touch with location between the digestion juice of water animals as well as the feed, as well as enhance the capacity of aquatic pets to feed the feed.

At the same time, because of the low intake of aquatic pets, the mixing harmony of the feed is needed to be mirrored in a smaller variety, which also requires the aquatic feed to have a better pellet size.

As an example, the shrimp feed need to all travel through the 40-mesh analytical filter, and the content on the 60-mesh sieve need to be less than 5%, so the micro-grinding procedure has to be taken on.

In the secondary pulverization process, the materials mixed in the very first time are raised by the lift and after that go into the silo to be shattered, and afterwards go into the mini pulverizer. Micro-pulverizers are generally made use of in the processing of aquatic feeds, as well as vertical-axis micro-pulverizers are usually made use of, which are furnished with effective wind separation tools, and after that go into the rotating grading screen for screening.

The purpose of configuring the rotary grading screen right here is mainly to eliminate the fine fluff developed by the coarse fibers in the feed throughout the pulverization procedure, due to the fact that the existence of these great fluff is easy to stick to the die opening of the fish feed extruder device up until the die opening is obstructed, triggering Close down for cleaning, so it has to be removed.

The cleaned up products undergo second batching as well as blending. Given that the fineness of the products getting in the secondary batching blending bin is above 60 mesh as well as the density is small, unique interest should be paid to the sensation of arching.

In order to stop this sensation, on the one hand, the eccentric sub-expansion hopper can be utilized, and also on the other hand, all the material discharge devices that have undergone ultra-fine grinding utilize an impeller feeder, which not just has an arch breaking device, however also can flexibly readjust the circulation rate. dimension. Different raw materials go into the secondary mixer after additional batching.

There is an artificial feeding port over the secondary mixer, which is mostly utilized for the enhancement of trace ingredients. At the same time, there is a liquid addition mechanism on the mixer for the addition of oil; one is for the addition of water. In the second mixing process, numerous products need to be totally mixed, and also the coefficient of variation CV is less than 7%, which is the key to making certain item quality.

Consequently, the mixer needs to pick a model with outstanding performance, such as double-shaft horizontal paddle mixing It has high mixing uniformity, high result and also rapid mixing rate. After additional squashing as well as secondary active ingredient mixing, the material gets in the succeeding process-- growth granulation procedure-- with fish feed extruder machine.

4. Extrusion process by fish feed extruder device.

In the extrusion process, the material actually undertakes a cooking procedure under the problems of heat, high humidity as well as high pressure.

Throughout this fish feed extruder equipment procedure, the physical as well as chemical homes of the product changed highly, as well as at the moment when the product was squeezed out from the die hole, the water in the feed was promptly converted from liquid to aeriform state as well as discharged from the feed because the stress instantly went down from high pressure to regarding 100kPa.

Therefore, the product is extruded by fish feed extruder equipment to form the so-called extruded feed. Since this kind of feed not only has the advantages of basic tough pellet feed - excellent palatability, prevents automatic grading of products, is easy to transfer, aids digestion, lowers waste in the feeding procedure, etc, but additionally has special benefits:.

In the feed, the starch has a high degree of gelatinization by fish feed extruder maker, the healthy protein is a lot more digestible, and also the use price of the animal feed is improved; it has excellent floatability, which is easy to observe the feeding circumstance of the fish, as well as can manage the water contamination to the maximum degree. These are also the main reasons that extruded feed is extensively made use of.

There are many sort of clothes dryers can be used after fish feed extruder device. When the size of the pellets is less than 4mm, a vibrating fluidized bed dryer can be picked; when the diameter of the pellets is greater than 4mm, a belt clothes dryer can be chosen, or a straight float dryer can be straight selected.

Since this kind of clothes dryer can make the material in a semi-suspended state on the entire display surface area, it can not just make sure the drying impact, however additionally minimize the damages to the pellets. After the product is dried, it enters the exterior splashing system.

The external spraying of the pellets is generally to fulfill the fish's power needs and also reduce the loss of heat-sensitive compounds throughout processing. The nutrients that ought to not be added in the previous process can be supplemented by external spraying, and at the same time, the palatability of the feed can be enhanced and also the powder web content can be decreased.

The optimal working temperature level for this procedure is around 80 ℃. After the material travels through the exterior splashing system, it can get in the counter-flow cooler for air conditioning.

5. Completed product packaging.
The cooled down product is lifted by the elevator and afterwards crushed into the aircraft rotating screen for classification. The grading screen used after fish feed extruder machine is generally a two-layer filter, and the material on the reduced filter is the finished product, which can be directly participated in the ended up product storage facility, and afterwards considered and packaged. The material on the top sieve requires to be gone back to the crusher for squashing. The material under the lower sieve is normally finely crushed, which can be gone back to the batching container as waste.

The fish feed extruder machine production procedure evaluated above is the traditional setup of the present marine extruded feed handling modern technology. Utilizing this process, sinking feed, sluggish sinking feed and also drifting feed can be produced.

Although extruded fish feed extruder maker modern technology has actually been recognized by many suppliers as a new type of processing modern technology, it has not been commonly made use of because its investment is a lot larger than that of tough pellet feed processing modern technology.
