Famsun unveils advanced extruder upgrades at VICTAM Latam

BRAZIL – Famsun has taken extrusion technology a step further with the unveiling of its upgraded H Series twin-screw extruder at VICTAM Latam, held from September 16–18 in São Paulo, Brazil. 

The redesigned system enhances hygiene, efficiency, and automation in aquafeed and pet food production, aligning with the industry’s growing demand for smarter, more adaptable feed processing solutions.

The new extruder offers improved accessibility and hygiene, enabling operators to clean the entire machine with a simple water flush. It also reduces start-up waste by up to 80% in the pre-conditioner, minimizing rework and material loss.

“This machine is an ideal choice for aquafeed production thanks to its intelligent control system and consistent quality,” said David Ma, Deputy Director of Famsun’s R&D Institute in an interview with Aquafeed.com. 

“It’s also easy to operate and maintain, with a professional configuration that ensures broad applications and reliable, stable performance.”

Famsun’s upgraded model is equipped with a pressure control unit to enhance bulk density when producing sinking feeds, thereby increasing production capacity. 

The company has also developed a micropellet module capable of using a die size as small as 0.3 mm to produce floating pellets of 0.5 mm and sinking pellets of 0.4 mm, ideal for early-stage aquafeeds.

At the core of the system lies Famsun’s FIMCOS SCADA control platform, which manages the production line, while the Manufacturing Execution System (MES) collects real-time data for performance tracking, preventive maintenance, and quality assurance. The system can also integrate with various ERP platforms, including SAP and Amazon.

Meeting new processing demands

As aquafeed formulations diversify globally, feed manufacturers face new challenges in raw material handling and conditioning. Famsun’s upgrades address these shifts with flexible pre-conditioning and screw configurations tailored to different regional recipes.

“There are many different raw materials used in different countries, some with very high fiber content,” Ma explained. “Nowadays, feed companies need more intensive pre-conditioning to soften the fibers and help raw materials absorb as much moisture as possible.”

Famsun’s database-driven system helps customers select the optimal screw setup for their local ingredients, ensuring efficiency and consistency.

Extrusion versus pelleting

While extrusion is gaining traction in markets such as Ecuador, where shrimp feeds use more plant-based proteins, pelleting remains dominant in Asia due to higher fishmeal content and protein requirements.

“With extrusion, you can achieve much higher production capacity per line—15 to 20 tons compared to a maximum of around five tons with a pellet mill,” Ma noted. 

“For producers who need higher capacity and have the necessary investment, extrusion is the best choice. But if financial resources are limited, pelleting can still be a practical option.”

As China’s aquaculture sector shifts toward high-value species, the move toward extruded feeds is accelerating. Ma said this trend represents a major opportunity for Famsun.

“We have to provide customers with a complete solution,” he emphasized. “That means not just extrusion technology, but also systems like vacuum coating. These ensure optimal oil absorption and nutrient retention, preventing leakage and preserving feed quality.”
