FISH FEED AUXILARY PELLETIZING EOUIPMENT FOR SALE
This covers 7 essential auxiliary equipment. Each one has a different role in fish/shrimp feed production lines.
Crushing equipment break down raw materials. Mixing equipment ensure uniform ingredient blending. Drying equipment eliminate surplus moisture from pellets. Spraying equipment add oil and other substances onto pellet surfaces. Cooling equipment rapidly reduce pellet heat. Screening equipment sort qualified pellets from powder and broken particles. Packaging equipment handles weighing, bagging, and sealing.
Hammer Mill
Capacity: 1-25 T/H
Power: 30-160 kW
RICHI hammer mill is suitable for crushing raw materials of aquatic feed as well as raw materials of poultry, livestock feed and pharmaceutical industries.
Ultrafine Grinder
Capacity: 1-10 T/H
Power: 90-220 kW
The ultrafine grinder can grind the raw materials to a fineness of 60-80 mesh, making the produced feed pellets easier to digest and absorb.
Single Shaft Ribbon Mixer
Power: 4-45 kW
Effective volume: 0.5-7.5 m3
Single shaft ribbon mixers are widely used in small and mediumsized feed pellet mills for mixing powder materials. The effective volume inside the mixer is large.
Single Shaft Paddle Mixer
Power: 11-55 kW
Effective volume: 1-6 m3
SLHJ series single shaft paddle mixer is widely used in feed, chemical, organic fertilizer and other industries. It is easy to maintain during use.
Belt Dryer
Number of mesh layers: 5
Drying area: 13 – 58 m3
Multy-layer belt dryer is a continuous drying equipment, which can be widely used in drying needs of wood, food, pharmaceutical, chemical and other industries.
Vacuum Spraying Machine
Capacity: 1-15 T/H
RICHI vacuum spraying equipment adopts self-developed vacuum spraying technology and is currently widely used in neutral or large aquatic feed factories and pet feed factories.
Counter-Flow Cooler
Capacity: 1-40 T/H
Cooling time: 6-15 minutes
Can meet the cooling needs of feed pellets. In addition, it can also be used for cooling various wood pellets, bio pellets and other pellets.
Vibrating Screen Classifier
Capacity: 2-50 T/H
Power: 0.18-0.55*2 kW
Suitable for various floating feedssinking feeds and slow-sinkingaquatic feed pellet production.
Cylindrical Primary Cleaning Screen
Capacity: 10-50 T/H
Screen aperture diameter: φ16~φ30
Its main task is to take out impurities found in raw materials, stopping them from moving into later stages and dirtying the feed.
Automatic Packaging System
Packaging speed: 2-8 minutes
Models: 6 types
By handling packaging tasks automatically, this system boosts efficiency, cuts costs, improves quality, and ensures compliance – creating a tighter production loop.
Typical Applications of Fish Feed Auxiliary Pelletizing Equipment
A feed production line is a system where core pelletizing equipment works together with auxiliary equipment. Auxiliary equipment is usually bought as a matched set. No matter what kind of line it is, this equipment plays a key role.
Floating Fish Feed Mill
Sinking Fish Feed Production Line
Shrimp Feed Pellet Plant
Pet Food Factory
Where Fish Feed Auxiliary Pelletizing Equipment Fits in the Production Line
Whether for fish feed, shrimp feed, or pet food production, the complete process follows this pattern.
Auxiliary equipment plays a key role in every stage – from raw material handling to pellet forming and final packaging. Working together with the core extruder/pellet mill, it ensures stable, efficient, and continuous output of qualified pellets.

FISH FEED AUXILIARY PELLETIZING EQUIPMENT Q&A GUIDE
Here you can find answers to FAQS about fish feed auxiliary pelletizing equipment. If you have any other questions that aren’t listed here, feel free to leave us a message. Tell us your inquiries regarding fish feed equipment, and we will provide professional solutions for you.
1. How are all these machines connected?
+
Feed production line equipment connects mainly by material flow order through conveyors..
Common conveyors in fish feed lines include:
Bucket Elevators (for vertical movement)
Screw Conveyors (for horizontal movement)
Transfer points usually have guide plates and valves to prevent blockages/residue and ensure smooth material flow.
2. What’s the difference between drying and cooling? Aren’t they the same?
+
Drying and cooling are different.
Drying removes water using hot air after pelletizing, preventing mold.Cooling lowers temperature with normal-air after drying, bringing pellets near room temp (3-5°C cooler) to avoid clumping/oxidation.
They serve different purposes and are both essential separate steps.
3. Is waste from sieving thrown away or reused?
+
It will not be discarded. Fine powder without mold/impurities goes back to the mixer/pelletizer for reprocessing. Unqualified coarse particles/chunks get crushed first, then proportionally mixed into new materials for secondary granulation.
This reduces raw material waste, cuts costs, and maintains final product particle size consistency.
4. Is Spraying equipment necessary?
+
Not necessarily, but it is recommended if you pursue high feed quality.
The spraying system’s role is to:
Add fats/oils, increase energy value;
Add heat-sensitive nutrients like vitamins, probiotics, attractants;
Improve pellet appearance and palatability.
If your formula has high oil content, needs heat-sensitive nutrient addition, or requires improved palatability/appearance, then coating equipment is almost essential.
Only some very basic, extremely low-fat sinking pellets might choose not to use a coating system.
