This is a project about shrimp feed pellet making machines in Sri Lanka. A small-scale shrimp feed manufacturer located near Galle, supplying semi-intensive and intensive pond shrimp farms, needed to upgrade its production capacity.

This is a project about shrimp feed pellet making machines in Sri Lanka. Sri Lanka’s aquaculture sector, particularly in the Southern and Western coastal regions, has witnessed substantial growth over the past decade. Shrimp farming plays a crucial role in local economies, with vannamei shrimp (Litopenaeus vannamei) and tiger shrimp (Penaeus monodon) dominating the market. Coastal farms rely on high-quality sinking feed to improve survival rates, promote uniform growth, and maintain feed efficiency.
A small-scale shrimp feed manufacturer located near Galle, supplying semi-intensive and intensive pond shrimp farms, needed to upgrade its production capacity. Their previous setup included small hammer mills and basic pelletizers, which produced inconsistent pellet sizes, leading to feed waste and suboptimal growth performance.
To address these challenges, the manufacturer opted to purchase a single SZLH350 shrimp feed pellet machine from RICHI Machinery. The rationale for buying a single machine instead of a complete line was driven by several factors:
This approach allows the manufacturer to enhance feed quality and operational efficiency without major infrastructural changes.
Name:
shrimp feed machine
Country:
Sri Lanka
Date:
2025
Capacity:
1–1.4 T/H
Model:
SZLH350
Main Motor Power:
55 kW
Conditioner power:
4 KW
Finished Pellet Diameter:
1.5–4 mm
| Parameter | Specification |
|---|---|
| Main Motor Power (kW) | 55 |
| Feeder Power (kW) | 1.5 |
| Conditioner Power (kW) | 4 (custom triple-layer design) |
| Ring Die Diameter (mm) | 350 |
| Finished Pellet Diameter (mm) | 1.5–4 |
| Production Capacity (T/H) | 1–1.4 |
The triple-layer conditioner includes:
This advanced conditioning system ensures that the machine produces durable, sinking pellets with minimal breakage and excellent water stability, which are critical for pond-based shrimp farming.
The SZLH350 efficiently handles these raw materials, producing sinking shrimp feed pellets that maintain their integrity in pond water.
Major functional advantages include:
It is important to note that the SZLH350 cannot produce floating feed, making it ideal for Sri Lanka’s pond-based shrimp farming systems.
The SZLH350 was transported via sea freight to Colombo Port, Sri Lanka’s primary commercial port. Sea transport is preferred for heavy pelletizing equipment, providing secure and cost-effective delivery.
Sri Lanka’s shrimp farming industry continues to expand, driven by export demand and improved aquaculture practices. The SZLH350 single-machine shrimp feed pelletizer provides:
Investing in RICHI Machinery’s shrimp feed pellet mills, ring die pelletizers, and pellet presses ensures manufacturers in Sri Lanka can produce premium sinking shrimp feed and remain competitive in a growing aquaculture sector.
The SZLH350 shrimp feed pellet making machine in Sri Lanka demonstrates that even a single high-performance machine can transform feed quality, efficiency, and farm productivity. With triple-layer conditioning, ring die pelletizing, and RICHI Machinery’s full support, medium-scale feed producers can achieve sustainable, high-quality shrimp feed production, tailored to the country’s semi-intensive and intensive pond aquaculture systems.
