1. What's floating fish feed extruder?

As a result of the advantages of floating fish feed extruder puffing, increasingly more feed mills have begun to puff aquafeed.

At present, the main working principle of the floating fish feed extruder utilized in the floating fish feed mill is to deal with the powdery product having a certain amount of starch (more than 20%) via a conditioner, to make sure that the moisture web content of the product can reach 25% to 27%, and the temperature level is raised to 80 ℃ ～ 100 ℃.

The floating fish feed extruder contains a feeding system, a transmission system, an extrusion system, a releasing die and also an electric control system. The relieved and also solidified material goes into the screw extrusion zone.

Because the volume of the extrusion area slowly decreases along the axis, the pressure on the product progressively enhances, as well as the compression proportion can reach 4 to 10.

The material is pressed by the floating fish feed extruder screw extrusion, and accompanied by strong shear as well as friction, the pressure and also temperature level increase sharply. Under the action of heat as well as high pressure, the starch in the product can be primarily completely gelatinized, and also the healthy protein is partially deformed.

( 1) The entire floating fish feed extruder is made from stainless steel, which is hygienic, risk-free and also dependable, very easy to tidy.
( 2) The floating fish feed extruder layout follows automated production line manufacturing, with little impact and also less labor. The devices is simple to operate, saving effort and time, and also reducing labor consumption.

With the quick development of the aquatic feed market, the residential demand for water feed has actually been driven. According to this market need, RICHI has investigated and also established different kinds of floating fish feed extruders.


2. Refine flow of freshwater fish feed production line:

The floating fish feed extruder embraces twin-screw extrusion modern technology, incorporated with Richi Machinery's experience in puffing technology study for many years, and also is a new generation of puffed food equipment made and also produced to fulfill the requirements of food and also associated markets.

The floating fish feed extruder production line has the advantages of stable manufacturing performance, versatile operation, totally automatic production procedure, lovely appearance (utilizing stainless-steel product), etc.


Resources preparation → mixing → sharing → extrusion → conveying → drying out → oil injection → flavoring → cooling → testing → product packaging

（ 1 ） Raw material cleansing

Receipt of raw corn and soybean dish wholesale; the clean-up process is all operation units that pass the corn and also soybean dish that has passed the evaluation of the raw product examiner right into the silo.

In this process, the impurities in the raw materials are to start with eliminated by the impurity elimination devices, and then carried to the silo as intended by the obtaining devices and the demagnetization tools.

The floating fish feed extruder production line tools includes obtaining devices (such as unloading pits, systems, etc), communicating equipment, primary cleansing screens, and also magnetic splitting up gadgets (such as permanent magnet drums, irreversible magnet drums, and so on).

For the receipt of bagged basic materials, it suggests that the loading and also dumping employees unload the raw materials that have actually passed the examination of the raw product examiners as well as keep them nicely in the stockroom.

In the process of getting the goods, four factors must be done:
Accurately count the quantity;
There is no top quality issue in the raw products;
The obtaining path is correct;
The obtaining setting is clean.

（ 2 ） Ingredient process

The batching procedure is to evaluate the raw materials in the batching container from the feeder under each batching container to the batching according to the formula needs. After each resources is considered by the batching range, the raw product is delivered to the powder storage space silo.

The active ingredients are evaluated from the silo, these considered raw materials enter the powder silo, a small amount of product as well as premix are added straight and manually weighed and after that took into the silo for mixing. The quality of the batching procedure directly affects the precision of item batching.

（ 3 ） Crushing procedure

The pulverization process means that the raw materials to be pulverized in the silo are sent out to the crusher to be pulverized right into powder, and afterwards sent out to the silo to be mixed by the conveyor before use. The objective of this procedure is to regulate the pellet dimension of the product.

The layout performance of the crusher in this process figures out the production capability of the procedure devices, and also it is likewise the process with the largest power consumption in the manufacturing of powdery products.

（ 4 ） Mixing procedure

In the blending procedure of floating fish feed extruder plant, the smashed resources are discharged from the mixing container into the mixer, and oil is contributed to the feed in the mixer through the fluid addition system as needed to make the elements evenly blended to accomplish the desired blending impact harmony.

The product discharged from the mixer is the ended up product, which is directly sent out to the product packaging process of the finished item for product packaging and leaving the floating fish feed extruder assembly line. When generating pellet feed, the blended powder is sent out to the silo for granulation.

In order to make sure the efficiency of the mixer, maintenance workers need to consistently examine and fix the equipment, and frequently evaluate the performance of the mixer.

（ 5 ） Granulation process

The blended material is appeased as well as solidified by magnetic splitting up from the granulation container, and after that sent out to the compression chamber of the floating fish feed extruder, compressed into pellet feed, cooled by a cooling tower, and also sieved by a screening equipment to acquire conventional granules.

Magnetic splitting up tools should be cleansed on a regular basis to avoid iron impurities from triggering damage to the floating fish feed extruder. When quenching and toughening up, the amount of floating fish feed extruder vapor need to be readjusted according to the demands of the pellet variety, and the ring die (aperture, compression proportion, material, and so on) should be selected according to the requirements of the pellet process high quality and also pellet temperature level and humidity.

According to the variety, interior temperature level as well as moisture, season and also other aspects, adjust the cooling tower to accomplish professional pellet temperature as well as humidity.

（ 6 ） Ended up item packaging

The feed made by floating fish feed extruder is evaluated from the ended up item storage facility by a packaging range, loaded right into packaging bags, after that classified and also secured by a packer, and then carried to the stockroom for piling by a transportation vehicle.
