Design of 3-4 t/h floating fish feed production line
Driven by the actual demand, the global aquafeed processing has been greatly developed and improved, the competition in the production and sales of aquafeed has become increasingly fierce, and the aquafeed has changed from bagged to bulk commodities.
Because of its high efficiency and versatility, extrusion processing of 3-4t/h floating fish feed making line improves feed digestibility more than other processing methods, and has the least adverse impact on the environment.
Therefore, 3-4t/h floating fish feed production plant extrusion methods are widely used in the production of aquafeeds. It is one of the feasible methods to use extrusion technology to build or renovate aquatic feed plants.
Extruded feed is a fluffy and porous feed made by feeding powdery raw materials into a floating fish feed extruder machine, mixing, shearing, tempering, heating, pressurizing, abruptly depressurizing and extruding, dicing and drying through the die hole. According to the different life and feeding habits of aquaculture animals, floating, slow sinking and sinking extruded aquafeed can be made.
The density of the product can be controlled by controlling the steam and water in the screw sleeve, and the product should be relieved before extrusion.
- The volume of floating feed is generally increased by more than 1∙5 times, and the volume of sinking feed is generally increased by 1∙05～1∙ 1 times;
- The size of the product is realized by controlling the speed of the cutter, and the length of the product is generally 1∙0 to 1∙5 times the aperture;
- The appearance control adopts different cutting methods according to the different characteristics of the product: the pellets with a diameter below Φ3∙0mm are cut with thin blades, and pellets with a diameter of Φ3∙0mm or more are cut with thick blades.
The quality of post-processing drying, post-spraying, cooling and grading of extrusion is also indispensable for 3-4t/h floating fish feed production line. The freshly extruded feed is very fragile, and a reasonable conveying system needs to be installed to transport the feed to minimize product damage, preferably a conveyor belt or an air conveying system.
In the 3-4t/h fish feed production line, the drying process is as important as extrusion. The aquatic feed should be dried slowly. If the drying is too fast, the core moisture of the feed will not easily diffuse, and the moisture will be transferred during the subsequent storage process, which will eventually lead to mold and deterioration of the feed.
To master the drying time, control the drying temperature to no more than 100℃, so that the thickness of the material layer and the drying time are in the best process condition.
After the product is dried, it should be sprayed with fish oil and other liquid raw materials while hot. The hot product can quickly absorb the liquid and maintain the water stability of the pellets. Aquatic feeds sprayed with fat are more palatable to fish, more beautiful in appearance and easy to be accepted by customers.
Cool down after spraying. Because the extruded pellets are still hot after spraying, without cooling, the product will condense and cause mildew and deterioration. The product must be cooled to a temperature not higher than 4℃ above the ambient temperature, so as to ensure the quality of the product.
Finally, it is required to sieve out the powder formed in the 3-4t/h floating fish feed production process flow before packaging.

Investment guide for 3-4 t/h floating fish feed production line
Some of the following issues should be considered when setting up a 3-4t/h floating fish feed production plant:
Necessary economic scale
The use of extrusion technology to process aquatic feed has certain advantages compared to hard pellet feed, but extrusion feed plants generally have large investment and high operating costs, and require special R&D institutions and marketing service systems. Therefore, there needs to be a certain amount of production and sales to reach the break-even point.
As the era of excess profits in extruded feed comes to an end, the amount required to meet the break-even point is gradually increasing. The scale of extruded aquatic feed plants is generally above 1t per hour, and the 3-4t/h floating fish food production lines in developed countries are generally above 10t/h. Therefore, specialization and achieving the necessary economies of scale need to be considered.
Product requirements
When choosing extrusion equipment and designing extrusion process of 3-4t/h fish food production line, the first thing to consider is the requirements of the product. (Related product: Floating Fish Feed Extruder Machine)
- Shape and size requirements;
- Density requirements;
- Nutritional requirements;
- Water stability requirements;
- Appearance requirements.
The nature and selection of raw materials
The choice of floating fish feed formulation has a decisive impact on the quality, consistency, nutritional composition, form and economy of the finished product; the choice of raw materials should not only take into account the nutritional requirements, but also consider the processability.
The crushing particle size of the raw material has an important influence on the appearance quality of the finished product, and also affects the extrusion production of 3-4t/h floating fish feed production line.
①Protein
Protein is the most important component of aquatic animal feed, and usually the content of protein in the entire feed composition is 25% to 60% or more. It is divided into two categories: vegetable protein and animal protein.
The water absorption and cohesion of vegetable protein are better than those of animal protein, but the types of amino acids that make up vegetable protein have certain limitations. (Related product: Fish Feed Production Plant)
②Starch
In fish feed, starch is usually the second most important ingredient, and the content of starch can be 5% to 60%. Recommendation: The starch content of sinking material is 10% to 15%, and the starch content of floating feed is not less than 20%.
In 3-4t/h floating fish feed production line process, carbohydrates function as binders, suspending agents, viscosity makers, and emulsifiers. It is an important determinant of many structural and special sensory properties in extruded products.
③Fat
Fats or lipids are also an important ingredient in aquatic animal feed, and they are a good source of energy. Under normal circumstances, its internal content does not exceed 22%, which is beneficial to energy consumption and wear of extrusion parts.
The composition of lipid compounds in extrusion formulations can increase the taste and energy content of the product, as well as alter the texture of the product. High levels of lipid compounds reduce swelling.
The lubricating effect of the lipid compound reduces the amount of thermal energy dissipation of mechanical energy and can have an impact on the type of fish food extruder configuration required for a product.
④Fiber
Cellulosics, including cellulose, hemicellulose, and lignin, are often used as fillers to provide nutrients and to help change the texture of some products. In some products only a small amount of fiber can be added to improve swelling, higher levels will reduce swelling.
Requirements for crushing particle size
- When the diameter of the die hole is less than 3mm, the maximum particle diameter should not exceed 1/3 of the hole diameter;
- When the diameter of the die hole is greater than 3mm, the maximum particle diameter should not exceed 1.5mm;
- The distribution range of particle size should be as small as possible.
structure of floating fish feed extrusion machine
It is required that the floating fish food extruder for 3-4t/h floating fish feed production line has a reasonable structure and configuration, can provide sufficient and accurate operating conditions, and can reasonably use various energy inputs to reduce operating costs.
①Template
In order to maximize efficiency, two sets of formwork and formwork support devices should be considered for quick product changeover.
②Extrusion parts
The design of the extruded part directly affects the processability. The discharge end of the extrusion cavity should be equipped with a device for sorting the material flow field to reduce the difference in pellet length. There should be a pressure relief device on the extrusion cavity to facilitate the processing of products with larger density.
There should also be a temperature control device on the extrusion cavity to facilitate the control of processing conditions in 3-4t/h floating fish feed production line.
③Preconditioning device
Whether the preconditioning device is matched will directly affect the product quality and operating cost. The preconditioning device in the 3-4t/h floating fish feed production line should be able to meet the needs of the output, and also should be able to leave room for the addition of various liquids.
④Auxiliary facilities
Whether the auxiliary facilities are matched will directly affect the operability of the 3-4t/h floating fish feed production equipment. Auxiliary facilities include water addition systems, steam addition systems, other liquid addition systems, temperature control systems, etc.
Processing conditions
①Density control
Density control mainly includes: the control of steam and water in the extrusion cavity, the temperature control of the extrusion cavity, and the pressure relief control of the product before extrusion.
②Size control
Size control is mainly to control the range of cutter speed.
③Appearance Control
The rotation speed of the cutter and the form of the cutter have an important influence on the appearance of the product. Different cutting methods can be used according to the characteristics of different products.
④Measuring Control
Requires accurate metering control of material entering the extrusion system; feedstock, steam, water, and/or other liquids can be added to the system in precise proportions, and steam, water, and/or other liquids can be added exactly as needed place to go.
Accurately metering the amount of material entering the extrusion system of 3-4t/h floating fish feed production line is the basis for determining how much steam, water and/or other liquids should be added. This is important for the stable operation of the system.
Steam quality control
High quality steam is required.
Realize automatic control
The purpose of realizing automatic control is to enable producers to master their technological process and produce their products; it is realized under the premise of manual control. When a floating fish feed manufacturer needs to develop a new product, he needs to use manual control to explore various operating parameters, and then input the parameters into the computer to achieve automatic control.
The meaning of automatic control:
- Reduce product waste;
- Improve product stability;
- Improve the operation effect of the operation;
- Provide 3-4t/h floating fish feed production process records;
- Reduce water and electricity consumption;
- Improve security;
- Provide convenience for product quality prediction, monitoring and control.
project report on 3 t/h floating fish feed production line
In order to further expand the market scale and consolidate the development achievements, after various investigations and studies, the 3t/h floating fish feed production project client finally decided to cooperate with Richi Machinery, which has rich experience in aquatic engineering construction.

Process flow of 3 t/h floating fish feed production line
01 Ingredients:
Mix the raw materials rapeseed meal, fish meal, peanut meal, soybean meal and flour according to different proportions.
02 Pulverization:
Put the ingredients into the fish food pulverizer to preliminarily pulverize the raw materials.
03 1st Mixing:
The preliminarily pulverized raw materials are mixed in the mixer through the sealed conveyor belt.
04 Ultrafine Pulverization:
The raw materials are conveyed to the hammer mill feed grinder through a sealed conveyor belt, and the mixed raw materials are further pulverized. The material is crushed at high speed by the micro pulverizer.
05 2nd Mixing:
The raw materials are superfinely pulverized and mixed in a mixer through a sealed conveyor belt.
06 Extrusion:
The material from the mixing section is heated to 85℃ by high temperature steam to gelatinize. This floating fish feed production line process produces a fully structured matrix in the extruded granules containing soluble sugar and fibers, which increases the volume of the granules and turns them into a porous structure, can absorb more fat. The batch is then made into the desired granules using a floating fish feed extruder machine.
07 Drying:
The moisture content of the extruded fish pellets is higher than the moisture content specified in the product specification, so it needs to be dried by a dryer. The fish feed dryer machine volatilizes the excess water in the feed through electric heating, and finally makes the water content of the product reach the specified standard.
08 Cooling:
The finished pellets enter the counter-current pellet cooler machine for cooling, the feed temperature is lowered from 50-60℃ to normal temperature, and the cooled pellets are sent to the finished product warehouse through conveyors and elevators.
09 Packaging:
An electronic packing scale is installed under the finished product warehouse. The automatic bagging machine automatically quantifies the packaging according to the set amount after debugging, and then sews the pockets by the sewing machine and automatically transports them to the stacker to complete the processing process.
Driven by the actual demand, the global aquafeed processing has been greatly developed and improved, the competition in the production and sales of aquafeed has become increasingly fierce, and the aquafeed has changed from bagged to bulk commodities. Because of its high efficiency and versatility, extrusion processing improves feed digestibility more than other processing methods, and has the least adverse impact on the environment.
