sinking fish feed pellet process
— Richi Machinery —
RICHI has always been at the forefront of fish feed pelleting technology and attaches great importance to the innovation of sinking feed production technology.
There are two main processes for producing sinking fish feed pellet: using a pellet mill to produce sinking fish feed pellets and using a feed extruder to produce extruded fish feed pellets.
Among them, the method of using pelleting process to produce sinking fish feed pellet is still a commonly used process by many sinking fish feed manufacturers. However, with the development of fish farming industry and the continuous improvement of sinking fish feed production technology, many places have begun to use feed extruders to produce sinking fish feed pellet.
As a well-known feed machinery manufacturer, no matter which process customers choose to use to produce sinking fish feed pellet, RICHI can provide the best solution and a full set of fish feed pellet machine.
Pelleting process flow: Raw material receiving and cleaning – coarse crushing – first mixing – second crushing – second mixing – pelleting – drying – spraying – cooling – screening – packing
Extrusion process flow: Raw material receiving and cleaning – coarse crushing – first mixing – second crushing – second mixing – extrusion – drying – spraying – cooling – screening – packing
Receiving and storing raw materials
The starting stage of the entire sinking fish feed production line is the receipt and storage of raw materials. With more than 20 years of professional experience in storage equipment design and manufacturing, RICHI can build a reasonable raw material storage solution for you.
First crushing and first mixing
The first crushing of raw materials, also called coarse crushing, is mainly aimed at crushing materials that account for a relatively large proportion in the feed formula and improving the working efficiency of ultrafine powder in subsequent processes.
The main equipment used is the hammer mill. After the crushing is completed, the materials are batched through the batching scale and then enter the feed mixer for uniform mixing.
Second crushing
Aquatic organisms, such as fish, shrimp, crab, etc., have short digestive tracts and poor digestion ability, so the raw materials need to be crushed to a finer particle size, so a second crushing is required. The second crushing will use an ultra-fine grinder.
Second Mixing
According to the feed formula, the trace elements, premixes, oils and fats that need to be added are fed into the feed mixer through the feeding port and mixed with the crushed bulk materials to form the raw materials to be granulated.
Pelleting section (necessary for pelleting process)
The main equipment used in this section is our SZLH series of fish feed pelletizer, which can be equipped with a double or triple layer modulator.
The mixed raw materials enter the modulator through the feeding device of the feed pellet machine, where they are mixed with hot steam, and then enter the pelletizing chamber through the discharge cone trough, where they are pressed into pellets by the ring die and roller. Finally, the pellets are discharged through the membrane holes and cut into pellets of the required size.
Extrusion section (necessary for extrusion process)
The main equipment used in this section is the feed extruder, which can be a single screw extruder or a twin-screw extruder according to the needs. RICHI has always been at the forefront of feed machinery technology, providing the most advanced extrusion technology equipment for the production of sinking fish feed pellet.
Drying section
The moisture content of the feed pellets extruded by fish feed pelletizer is higher than 13%. Once the moisture content of the pellets is higher than 13%, they are prone to mold and deterioration when stored in the air. Therefore, they need to be post-dried in a dryer to reduce their moisture content to less than 13% so that they can be stored in the air for a long time.
Spraying Section
A certain amount of oil is sprayed on the surface and inside of feed pellet. Its main function is to increase the nutritional content of feed pellet and improve the palatability of feed pellet.
Cooling section
The temperature of the feed after pelleting or extrusion is relatively high and the pellets are relatively soft. In order to increase the hardness of the pellets, a cooler can be used for cooling.
The pellet cooler adopts the counter-current cooling pellet. The cold air and hot pellets exchange heat in the cooling chamber and then are blown out through the suction system to achieve the purpose of cooling.
Sinking Fish Production Feed line
This is the standard process flow for sinking feed pellet, but not every customer needs to use all the work sections. Each work section in our entire feed production line is modularly designed, and we can add or reduce work sections according to specific needs; and the equipment in each work section will also be adjusted according to the needs of raw materials, capacity, etc.

Frequently Asked Questions
what are the benefits of using sinking feed to feed fish?
Meet the feeding needs of bottom aquatic organisms. After the sinking feed pellet sink to the bottom of the water, bottom aquatic organisms such as catfish and loaches living on the bottom of the water can eat directly on the bottom of the water;
Nutritionally balanced. The feed pellets produced using a specific formula are nutritious and can meet the normal growth needs of fish.
Reduce waste. Compared with the method of directly spreading the raw materials into the water, feeding the fish with pellets can greatly reduce waste and reduce water pollution.
can the feed pelletizer used to produce sinking aquafeed be used directly to produce shrimp feed?
Both the feed pelletizer with double-layer modulator and the feed pelletizer with triple-layer modulator can be used to produce sinking fish feed, but if you want to produce shrimp feed, you can only use the feed pelletizer with triple-layer modulator because the degree of maturation is relatively high when producing shrimp feed pellet.
So if you want to produce both sinking fish feed and shrimp feed, you can directly equip the pellet mill with a three-layer modulator. Of course, you can also equip a pellet mill with a double-layer modulator and a pellet mill with a three-layer modulator according to the output and other requirements.
If I want to invest in a small feed mill, such as 1t/h fish feed mill, do I also need all the equipment mentioned above?
Of course not. First of all, the above is a standard process flow for fish feed production. Each process section is modularly designed and can be increased or decreased according to the specific needs of each customer.
Secondly, the equipment equipped in each work section will also be adjusted according to the customer’s raw material types and capacity. For example, some customers may not need to use ultra-fine grinders, and ordinary grinders can meet production needs.
In addition, all our solutions are customized. All processes of the entire feed production and the required equipment will be customized and produced according to the actual situation of each customer.
If I want to produce both floating fish feed and sinking fish feed pellet, do I need to purchase two feed production lines to meet my production needs?
No. Some feed mills only produce a single type of feed, such as sinking fish feed, floating fish feed, shrimp feed, chicken feed, cattle feed, etc.; there are also a large number of feed mills that produce multiple types of feed at the same time, which is what we call a compound feed pellet mill.
A compound feed pellet mill does not need to be equipped with two completely different feed production lines, because many equipment can be shared, such as grinders, mixers, coolers, packing machine, etc., as well as auxiliary equipment on the feed production line, can all be shared.
Therefore, you only need to equip different feed pellet machines, feed extruders, etc. according to specific production needs to achieve the purpose of producing a variety of feeds, without the need to purchase two complete feed production lines.
