sinking fish feed production line PROCESS DESCRIPTION
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.
Complete sinking fish feed production process
sinking fish feed production line – PELLETIZING/EXTRUSSION Process: Detailed Overview of Two Machines
If your formula is simple and low in oil, and you aim to produce conventional, high-volume sinking pellets, then a ring-die fish feed pellet machine is the more cost-effective choice — it’s low-cost, stable to operate, and offers good output.
However, if your formula is high in protein, fat, or contains many functional ingredients, and you want to make higher-end, palatable sinking feed, an extruder is the better option. It thoroughly cooks the raw materials, creating dense yet digestible pellets that are more competitive.

How to choose a suitable SINKing fish feed production line?
When choosing a sinking fish feed production line, you should consider several key factors to ensure the equipment configuration matches your production goals:
2. Determine the type of sinking feed you want to produce
Regular fish feed can use dry extrusion machines, while high-quality fish feed is better suited for wet extrusion machines.
If you also want to make high-end formulas or multiple varieties (such as shrimp feed, specialty feed), twin screw extruders will have an advantage.
The higher your product positioning, the higher the requirements for extrusion processes.
3. Choose the equipment grade based on budget
The higher the budget, the more complete the available process configuration.
With limited funds, basic processes like crushing—mixing—pelletizing/extrusion—drying can meet regular sinking feed production needs.
For higher quality demands, you can upgrade to multi-layer dryers, automatic batching systems, or more advanced extruder models to achieve more stable pellet quality.
4. Consider Product Quality and Market Competitiveness
Your target market determines the equipment level. In price-sensitive regions, basic floating feed suffices.
However, if aiming for premium brands, entering competitive markets, or exporting, more mature extrusion technology is needed to obtain higher cooking levels, stable puffing effects, and uniform pellet appearance.
5. Assess whether multi-category production or future expansion is needed
If adding shrimp feed, high-protein feed, pet food, or expanding capacity in the future, select expandable equipment like wet or twin-screw extruders, reserving space for drying and crushing links.
For single-product, long-term stable operations, a basic production line meets needs.
FAQ about SINKing fish feed production LINE
If you have any questions about floating fish feed making machine or floating fish feed production line, you can first take a look at these answers.
1. 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.
?
2. 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.
?
3. 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.
?
4. 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.
