Part 1  Small-Scale Aquatic Feed Production Line Overview

Small-Scale Aquatic Feed Production Line Solution (Hourly Output: 500 kg – 2 tons)

Designed for startups and farms with self-production needs, this modular solution prioritizes cost efficiency and customization.

1.1 Key advantages over large-scale industrial feed mills include:  

(1) Cost-Effective Configuration

Semi-automated design reduces initial investment. Critical sections retain manual interfaces (e.g., manual batching), and economical fine-grinding equipment replaces costly super-micro grinding systems.  

(2) Flexible Process Design  

Scalable output from 500 kg/h (base module) to 2 tons/h. Compatible with both extrusion and pelletizing modes to meet diverse feed form requirements for aquatic species.  

(3) Compact Layout

Flat equipment arrangement minimizes workshop height (<6m), lowering steel structure costs. Core processes are centralized on the ground floor for optimized workflow.  

1.2 Ideal Applications

- On-site feed production for aquaculture farms  

- Regional small-scale feed processors  

- Trial lines for specialty feeds  

- Low-cost entry for startups  

Standard configurations include raw material pretreatment, precision batching, two-stage grinding, efficient mixing, conditioning & pelleting, cooling & screening, with optional modules like oil coating or vacuum post-spraying. Contact us for tailored solutions and quotes.  

Part 2 Introduction to the processing technology of small production line

2.1 300–500 kg/h Floating Feed Line

This line typically uses pre-processed powdered raw materials, which are fed into a hopper for fine grinding. The ground material then enters the mixing section to ensure uniformity. The blended mixture is stored in a buffer silo before proceeding to the expansion section.  

The extruder can be configured as a single or twin-screw model, ideal for standard floating feed production. Key features include:  

Ø High-quality alloy screws (wear-resistant)  

Ø Optimized length-to-diameter ratio for superior expansion  

Ø High-performance motors with body cooling systems  

Ø  Optional touchscreen control panel  

Post-expansion, materials are dried uniformly in a horizontal recirculating dryer, ensuring minimal breakage. Dried products are cooled, screened via an integrated system, manually packaged, and stored.

This design emphasizes simplicity, efficiency, and consistent product quality for small-scale floating feed production.  

2.2  800–1,000 kg/h Floating Feed Line

(1)

This line typically utilizes pre-processed powdered raw materials, which are fed through the inlet, lifted, and finely ground. The ground materials enter the mixing section for homogenization, then stored in a buffer silo before proceeding to the expansion section.

The extruder can be configured as a single/twin-screw model, suitable for standard floating feed production. Key features include:

Ø High-quality alloy screws (wear-resistant)

Ø Optimized length-to-diameter ratio for superior product expansion

Ø High-performance motors with integrated body cooling systems

Ø Touchscreen control panel (optional)

Post-expansion, materials are uniformly dried in a horizontal recirculating dryer to prevent breakage. Depending on formula requirements, dried products can be routed to a drum coating machine for oil application.

After oil coating, materials enter the cooler, pass through a screening system, and are manually packaged before storage. 

This design balances efficiency, automation, and adaptability to meet diverse production needs.

(2)

This line adopts automatic batching for primary raw materials to reduce labor intensity. Granular and powdered materials are conveyed via elevators to batching bins. The pre-batched mixture enters the grinding section, following a pre-batch-then-grind process.

Ground materials are transferred to a mixer, where supplementary raw materials can be manually added. The blended mixture proceeds to the expansion section, equipped with a single/twin-screw extruder suitable for standard floating feed production. Key features include:

Ø High-quality alloy screws (wear-resistant)

Ø Optimized length-to-diameter ratio for superior expansion

Ø High-performance motors with body cooling systems

Ø Touchscreen control panel

Post-extrusion, materials are dried uniformly in a horizontal recirculating dryer to prevent breakage. Dried products are cooled, screened, manually packaged, and stored. An optional drum coating machine can be added for oil application.

This design prioritizes efficiency, automation, and product quality while minimizing manual intervention.

2.3 Economy Design (Manual Batching) -1.5-2 tons/H fish feed production line

This cost-efficient setup adopts manual batching. After cleaning, granular and powdered materials enter the pre-crushing bin. A wide-body fine grinder achieves a grinding fineness of 60–80 mesh. The crushed materials are then transferred to a dual-shaft paddle mixer, where liquids and premixes can be added.  

The blended mixture is stored in a buffer silo before extrusion. The extruder can be configured as single- or twin-screw, featuring high-strength wear-resistant alloy sleeves, premium gearboxes, optimized length-to-diameter ratios, gearbox cooling systems, and a touchscreen interface.  

Post-extrusion, materials enter a horizontal recirculating dryer with zoned temperature control for uniform drying and minimal breakage. After drying, the product undergoes oil coating and cooling, followed by screening and manual packaging.  

This solution offers economical investment, compact footprint, and high-quality output from core equipment. Flexible process design minimizes capital costs, achieving high cost-effectiveness.
