RICHI Machinery Launches 2T/H Shrimp Pellet Line in Thailand

In October 2025, RICHI Machinery proudly announced the successful installation and commissioning of a 2t/h complete shrimp pellet line for a Thai aquaculture enterprise. The client operates several medium-sized shrimp farms along Thailand’s eastern seaboard, a region renowned for its shrimp farming industry. Facing increasing demand for high-quality shrimp feed and the need to improve feeding efficiency and reduce feed wastage, the client sought to establish a dedicated shrimp pellet production line to support sustainable farm operations.

Thailand is one of the largest shrimp-producing countries in Southeast Asia. The client’s objective was to locally produce floating and sinking shrimp feed pellets tailored for different growth stages of shrimp, ranging from post-larvae to adult shrimp. This approach not only reduces dependence on imported feed but also allows better control over nutrition and cost management.

The feed formula designed for the project consists of fish meal (40-45%), soy protein concentrate (20-25%), corn gluten meal (15%), and vitamin and mineral premix (5-10%), with the remaining 5-10% comprising binders and stabilizers to ensure pellet integrity. The client required a system capable of producing 2 tons per hour of uniform, nutrient-rich pellets, with diameters between 1.5–4 mm for juvenile feed and 4–8 mm for grower feed.

Special project requirements included:

• Capability to produce both floating and sinking pellet types
• Compact plant layout to fit within the existing farm warehouse
• Moisture and temperature control to maintain pellet quality in Thailand’s humid climate
• Low energy consumption and easy operational automation

Plant Design and Production Process

RICHI Machinery provided a tailor-made process solution for shrimp feed pellet production, integrating advanced equipment and proven workflow strategies. The design optimized use of existing infrastructure, requiring only minor renovations for ventilation, electrical wiring, and moisture control.

The production process includes the following stages:

• Raw Material Handling: Ingredients such as fish meal, soy protein, and corn gluten are weighed and pre-mixed. Shredding ensures uniform particle size.
• Conditioning: A twin-screw conditioner adds steam and moisture to improve pellet binding and digestibility for shrimp. Temperature is precisely controlled to avoid nutrient loss.
• Pelletizing: The mixture passes through a high-efficiency shrimp feed pellet extruder capable of producing both floating and sinking pellets. Extruder dies are interchangeable to allow pellet diameter variation.
• Drying: Pellets are dried to reduce moisture content to 10–12%, ensuring shelf stability and preventing microbial growth.
• Cooling and Screening: Rotary coolers reduce pellet temperature, and vibrating screens remove fines.
• Packaging: Automated bagging and storage ensure minimal labor input and ready-to-distribute feed products.

Additional equipment includes conveyors, dust collection systems, and real-time monitoring devices for moisture, temperature, and pellet quality, ensuring continuous production without compromise.

Equipment Configuration and Technical Specifications

The 2t/h complete shrimp feed production line supplied to the client includes:

• Pre-mixer and feed hopper: Ensures consistent raw material blending
• Twin-screw conditioner: Optimizes moisture and temperature for high-quality extrusion
• High-capacity shrimp feed extruder: Produces 2 tons per hour of pellets
• Rotary dryer: Reduces moisture content to extend shelf life
• Rotary cooler: Maintains pellet structure and prevents breakage
• Vibrating screen: Ensures uniform pellet size and removes fines
• Automated packing system: Facilitates fast and hygienic product handling

All equipment is customized to Thailand’s three-phase electrical system, optimized for energy efficiency and operational stability.

Operational Advantages and Applications

The 2t/h shrimp pellet line provides several advantages to the client:

1. Feed efficiency improvement: Uniform pellet size and nutrient retention promote optimal shrimp growth.
2. Reduced dependency on imported feed: Local production cuts costs and enhances supply reliability.
3. Environmental benefits: Minimized feed waste reduces water pollution in shrimp ponds.
4. Scalable production: Ability to produce multiple pellet sizes for different growth stages.
5. Automation and operational simplicity: Low labor requirements with high consistency in output.

The system allows the client to quickly respond to market demand fluctuations while maintaining stringent quality standards.

This project underscores Thailand’s growing emphasis on sustainable, locally produced shrimp feed. By implementing a turnkey shrimp pellet solution, RICHI Machinery enables aquaculture operators to control feed quality, improve growth performance, and reduce environmental impact.

RICHI Machinery’s approach demonstrates that integrating advanced technology, tailored processes, and comprehensive support can transform shrimp farming operations, delivering both economic and environmental benefits.
