6-7 t/h fish feed plant design
The production process of 6-7t/h fish feed processing plant is very different from the traditional production process of livestock and poultry feed.
According to the characteristics of many varieties of aquatic feed, large changes in raw materials, high requirements for crushing fineness and poor fluidity of materials, the 6-7t/h fish feed production process is generally completed by secondary crushing and secondary ingredient mixing, and then through puffing, drying, external spraying, cooling, crushing and screening.
(1) Raw material cleaning and primary grinding
The raw materials used in 6-7t/h fish feed plants generally have two forms:
One is powder, they do not need to go through coarse crushing. For this kind of raw material, it can directly pass through the feeding pit and elevator, then enter the conical cleaning screen to remove impurities, then conduct magnetic separation, and directly enter the batching bin through the distributor or screw conveyor to participate in the first batching;
The other is the material that needs to be coarsely crushed – pellets. This kind of material enters the cleaning equipment through the unloading pit and the elevator to enter the cleaning equipment for impurity removal and magnetic separation treatment.
And then enters the to-be-pulverized bin, and then passes through the coarse pulverization of the fish feed pulverizer, and then enters the batching bin through the elevator and distributor to participate in the first batching.
For individual raw materials, such as shrimp shells, they can be directly put into the silo to be crushed after magnetic separation without initial sieving.
(2) The first batching and mixing
The first batching is mainly the preparation of raw materials, that is, the preparation of larger materials in the formula. This 6-7t/h fish feed plant process is mainly completed by electronic batching scales.
However, in the first batching process, special attention should be paid to the arching of the batching bin, which is mainly caused by the light bulk density and poor fluidity of the raw materials of aquatic feed, especially high-grade aquatic feed raw materials.
Therefore, certain anti-arching measures should be taken for the batching bin, such as the use of eccentric discharge, vibration motor, etc. The single-shaft horizontal ribbon feed mixer machine can be used for the first mixing, and the grease addition system must be considered on the fish feed mixing machine.
The first batching and mixing is also the pre-treatment process of ultra-fine grinding, which is mainly to reduce the variation range of material particle size, improve the working condition of the aqua feed pulverizer, improve the working efficiency of the fish feed pulverizer, and ensure the quality of the product.
(3) Secondary crushing and mixing of secondary ingredients
Due to the low food intake, short digestive tract and poor digestion ability of aquatic animals, the aquatic feed is required to have a finer particle size. In the secondary pulverization process, the materials mixed in the first time are lifted by the elevator and then enter the silo to be pulverized, and then enter the micro pulverizer.
Micro-pulverizers are now generally used in the 6-7t/h fish feed plant with vertical shaft micro-pulverizers, which are equipped with powerful wind separation equipment, and then enter the rotary grading screen for screening.
In the secondary mixing process, various materials must be fully mixed, and the coefficient of variation CV is less than 7%, which is the key to ensuring product quality.
Therefore, the aqua fish mixer equipment must choose a model with excellent performance, such as double-shaft horizontal paddle mixing machine，it has high mixing uniformity, high output and fast mixing speed.
After the material is crushed and mixed with secondary ingredients, it enters the subsequent 6-7t/h fish feed making process – the puffing and granulation process.
(4) Extrusion process
In the extrusion process of 6-7t/h fish feed plant, the material actually undergoes a cooking process under the conditions of high temperature, high humidity and high pressure.
During this process, the physical and chemical properties of the material changed strongly, and at the moment when the material was extruded from the die hole, the water in the feed immediately changed from liquid to gaseous state and was emitted from the feed because the pressure suddenly dropped from high pressure to about 100kPa.
Thereby, the material is extruded to form the so-called extruded feed.
After the material is extruded by the fish feed extruder machine, it forms moist and soft granules (with moisture content of 25% to 30%). At this time, it is best to use pneumatic conveying. Due to the high moisture content of the material conveyed by pneumatic, it must enter the fish feed dryer machine for drying, so that the moisture content of the material is reduced to about 13%.
After the extruded fish feed is dried, it enters the external spraying system. The external spraying of the pellets is mainly to meet the energy demand of fish and reduce the loss of heat-sensitive substances during processing.
The nutrients that should not be added in the previous process can be supplemented by external spraying, which can also improve the palatability of the feed and reduce the powder content. The optimum working temperature is around 80℃. After the feed pellets passes through the external spraying system, it can enter the counter-flow pellet cooler machine for cooling.
(5) Finished product processing and packaging
The cooled feed is lifted by the elevator and then crumbled into the plane rotary screen for classification. The grading sieve is generally a two-layer sieve, and the material on the lower sieve is the finished product, which can be directly entered into the finished product warehouse, and then weighed and packaged by automatic bagging machine.
The feed on the upper sieve needs to be returned to the feed crusher for crushing. The feed pellets under the lower sieve is generally finely crushed, which can be returned to the batching bin as waste.

Production Process of 6 t/h fish feed plant
01 Raw material receiving and initial cleaning:
Raw materials such as soybean meal are sent to the bucket elevator through the scraper conveyor, and then lifted to the cleaning screen to remove the sundries, and then the ferromagnetic sundries are removed by the permanent magnet cylinder and transported to the batching bin. During the initial cleaning of raw materials, certain waste residues will be generated, mainly waste straw rope, sand and gravel, and ferromagnetic debris.
02 Primary batching, mixing, primary crushing, secondary crushing:
All kinds of raw materials are weighed and batched by computer control and then entered into a double-shaft high-efficiency mixer for primary mixing, and the mixed materials are transported into the crusher for secondary crushing.
03 Secondary batching and mixing system:
All kinds of auxiliary materials are weighed and batched by computer control, and then enter the mixer together with the primary premix for secondary mixing, and the mixing process is completely sealed.
04 Extrusion——6t/h fish feed plant:
The mixed material enters the warehouse to be extruded, undergoes high temperature treatment through the twin screw extruder, and is conditioned by steam to mature the feed and achieve a certain degree of uniformity. Depending on the extruded pellet size of the product, the required puffing time is different.
The pellet size of the feed includes 1.0~2.0, 3.0, 4.0~5.0, and the corresponding design capacities are 11098t/a, 8623t/a, 5279t/a, respectively. The extruding capacity of each equipment is 5t/h, 8t/h, 10t/h, and one floating fish feed extruder machine is set up.
05 Drying system:
After puffing is completed, it must be dried to remove moisture.
06 Grease spraying system:
The dried extruded pellet is sieved and mixed with grease evenly by spraying machine. The process is a fully enclosed, fully automatic grease spraying system.
07 Cooling system:
After spraying is completed, enter the feed pellet cooler to cool and air dry.
08 Screening——6t/h fish feed plant:
It is lifted from the hoist to the grading screen, and the qualified ones are screened into the packaging process. This process will produce unqualified products, which will be recycled for the next batch of feeding.
09 Packing and warehousing:
The finished products are automatically stacked by robots and palletizers and transported to the warehouse for storage.
Note: In this project, a laboratory is set up to test some raw materials and finished products for protein, moisture, calcium, phosphorus and other indexes. In the testing process, reagents such as hydrochloric acid, ethanol, and EDTA will be used, which will produce laboratory wastewater and empty reagents.
Application Prospect of Floating Aquatic Feed
At present, many countries and regions with developed aquaculture industry are using extruded aquafeed in large quantities. In the United States, the feeds of salmon, rainbow trout, eel, lobster, channel fork tail, tilapia and koi are commonly produced by extruded technology, and 90% of the channel fork tail is fed with extruded feed.
In recent years, more and more attention has been paid to extruded aquatic feed, and some professional fish feed plants have been built and put into operation. (Related product: twin screw extruder for sale)
