1.6-3 T/H Raw Cereal Grain Extruder in Kazakhstan

This wasn't a project about upgrading an existing line or adding a single machine to a diverse feed mill. It was a greenfield venture to create a dedicated, export-quality aquafeed plant.

While they planned for a full line including micro grinders, mixers, coaters, and dryers, they knew the heart of the entire operation—the piece of equipment that would determine if their pellets would float or sink, and how efficiently fish would convert them—was the grain cooking and expansion unit.

They needed an industrial-strength, precision raw cereal grain extruder specifically capable of producing the highly expanded, uniformly cooked cereal pellet crucial for floating feed. After a global search that included high-profile European brands, RICHI Machinery’s RCYP series was selected.

Its proven performance in whole grain processing, its robust design suited for 24/7 operation in a new industrial setting, and its compelling cost-to-performance ratio made it the cornerstone of their ambitious plan. This led to the strategic purchase of a Raw Cereal Grain Extruder in Kazakhstan, a single, defining machine for their new national flagship facility.

Engineering Cereals for High-Performance Fish Feed

The core raw materials for the floating feed base are staples of Kazakh agriculture:

• Wheat: High-grade food wheat, selected for its consistent starch content and protein quality, which is critical for creating a strong, stable expanded pellet.
• Corn (Maize): Used in specific formulations to adjust energy density and expansion characteristics.

The processing objective was extremely precise and driven by aquafeed physics and biology: to produce a highly expanded, low-density, uniformly porous cereal pellet with near-total starch gelatinization (>95%) and specific buoyancy characteristics. The technical requirements were non-negotiable:

1. Controlled Expansion for Buoyancy: The extruded cereal pellet must have a precise bulk density (typically < 350 g/l) to ensure the final coated feed pellet floats for an extended period (60+ minutes).
2. Water Stability & Digestibility: The expansion must create a stable, honeycomb-like structure that absorbs steam and binders effectively during final feed extrusion, resulting in a water-stable pellet that doesn't disintegrate quickly, paired with highly digestible starch for optimal fish growth.
3. Consistency is King: For automated, high-speed aquafeed production, every cereal pellet must be virtually identical in size, expansion, and cook to ensure uniform final product quality.

As a facility designed for national supply and potential regional export, they required a machine with significant, reliable capacity. RICHI’s engineers, understanding the critical nature of expansion for floatation, recommended the Model RCYP200G Wet Process Whole Grain Extruder.

This high-capacity model was chosen as the production engine for their new plant:

• Type: Wet Process (Essential for achieving the high degree of starch cook, uniform moisture addition, and controlled expansion required for floating fish feed).
• Main Motor Power: 132 kW
• Screw Diameter: 200 mm
• Feeder Power: 1.5 kW
• Conditioner Power: 7.5 kW (The large DC420-3000 conditioner is vital for perfectly tempering the wheat/ corn meal before extrusion).
• Corn Output: 1.6-2.2 T/H (This high output ensures the cereal extrusion stage does not become a bottleneck for the entire feed line, which might produce 2-3 T/H of finished feed).
• Critical Feature: The three-bearing support with circulating thin oil lubrication was identified as essential for the planned continuous, high-pressure operation, ensuring unparalleled bearing life and shaft stability—the bedrock of consistent extrusion.

The Pivotal Role in a National Aquafeed Production Line

This RICHI raw cereal grain extruder is the first major thermal-mechanical process in the new plant. Wheat flour or corn meal is precisely metered into the preconditioner, where steam and water are injected to hydrate and begin cooking the starch.

This conditioned mash enters the extruder barrel, where the massive screws generate tremendous shear and pressure, completing the starch transformation into a viscous, hot dough. As this dough exits through a multi-hole die, the instantaneous pressure drop causes it to expand into long, porous, continuous strands, which are then cut into short, cylindrical pellets.

These expanded cereal pellets are then dried to a specific moisture content. They form the primary carbohydrate base. In the next stage, they are ground into a coarse meal, mixed with fishmeal, oils, vitamins, and binders, and then re-extruded in a secondary extruder to form the final floating fish feed pellets.

The quality of the initial expanded cereal directly determines the float rate, water stability, and physical durability of the final feed. By mastering this first step with the RICHI extruder, the Kazakh company ensures their entire product line meets international standards.

Shipping and Delivery to the Caspian Coast

The RCYP200G raw cereal grain extruder, a substantial piece of industrial equipment along with its large conditioner, was manufactured, test-assembled, and broken down into modules. It was packed into multiple open-top and standard containers and shipped from Qingdao Port, China.

Given the plant's location in Aktau, the most direct and cost-effective route was via the Port of Aktau, Kazakhstan itself, a major Caspian Sea port.

The shipment traveled by sea to a transit port like Baku (Azerbaijan) or directly across the Caspian, then by feeder vessel to Aktau. After customs clearance at the port, it had a very short truck journey to the construction site.

Technical Superiority: Engineered for Precision and Uninterrupted Operation

The selection of the RICHI raw cereal grain extruder in Kazakhstan was based on a calculated assessment of features that guarantee product quality and plant uptime:

• Precision Processing for Demanding Applications: Unlike generic extruders, the RCYP's design parameters for whole grain processing translate directly to superior control over the expansion of cereal meals. This control is absolutely critical for achieving the exact buoyancy required in aquafeed—a parameter where RICHI’s technology offered a proven advantage.
• Unmatched Drive Train Simplicity and Reliability: The gearbox design requiring no external cooling is a monumental advantage in a remote industrial location. It eliminates an entire ancillary system (pumps, chillers, pipes) that is a common source of failure and maintenance headaches, directly translating to higher operational availability.
• Superlative Wear Resistance for Starchy Abrasives: Cereal meals, especially wheat, are highly abrasive on extruder components. The use of special alloy steels for screws, barrel liners, and die plates ensures extended service life, protecting against unplanned downtime and maintaining precise die geometry for consistent pellet shape over long production runs.
• Industrial-Grade Bearing Solution for Heavy-Duty Service: The three-bearing arrangement with forced oil circulation is a feature found on extruders costing multiples more. It provides ultimate support for the long, high-torque screw, ensures perfect alignment under the extreme pressures of aquafeed extrusion, and offers superior heat dissipation—this is the engineering foundation for 24/7, year-round operation.
• Integrated Thermal and Functional Transformation: The machine is a continuous cooker-expander. It does not just puff the grain; it completely gelatinizes the starch, denatures proteins, and creates the specific porous microstructure necessary for subsequent binding and coating in the aquafeed process. This functional transformation is the value it adds to the raw flour.

Client Testimonial from Aktau, Kazakhstan

Following the successful commissioning and the first commercial production runs of sturgeon feed, the plant’s general manager reported: "Establishing this aquafeed plant was a national priority project, and the cereal extrusion stage was our single biggest technical risk. The RICHI raw cereal grain extruder has proven to be the reliable cornerstone we needed.

It delivers a perfectly expanded, consistent cereal pellet that gives our final feed excellent floatation and stability. The machine's construction is incredibly robust, and the simplified drive system gives us great confidence for continuous operation.
