1.6-2.5 T/H Cereal Grain Expansion Machine in Iran

This was not a project about launching a new commercial feed brand. It was a strategic capital investment to gain control over a critical part of their feed supply chain and reduce costs. Their existing feed mill had mixers and hammer mills, but it lacked the capability to thermally process and upgrade whole grains.

They needed a dedicated, industrial machine to perform this specific value-adding function. The search was for a reliable, high-capacity cereal grain expansion machine that could become a permanent fixture in their feed preparation hub.

After evaluating machinery from Turkish and European manufacturers, they found RICHI Machinery’s RCYP series to offer superior durability, simpler maintenance, and a more attractive total cost of ownership for their specific "in-house production" model.

This led to the installation of a Cereal Grain Expansion Machine in Iran, a single, purpose-driven machine that altered their entire feed economics.

Material Profile: Leveraging Local Grains for Nutritional Enhancement

The primary raw materials for this expansion process are grains central to Iranian agriculture:

• Barley: A widely grown, often cost-effective cereal in Iran, but with a hard seed coat and lower digestibility for monogastrics like poultry in its raw form.
• Corn (Maize): Cultivated locally and imported, used as a primary energy source.

The processing objective was clear and driven by animal nutrition science: to subject these whole grains to high-temperature, short-time (HTST) expansion to achieve several key transformations:

1. Gelatinization of Starch: To increase from roughly 30-40% in raw grain to over 85-90%, making the energy almost fully available to the animal.
2. Structural Disruption: To break down the tough fibrous structures (especially in barley), reducing gut fill and improving passage rate.
3. Denaturation of Anti-Nutritional Factors: To reduce levels of certain starches and proteins that interfere with digestion.

For their integrated operation, supplying feed to thousands of birds and hundreds of cattle daily, they needed a machine with substantial, reliable throughput. Crucially, they required the wet process to ensure thorough preconditioning and achieve the high degree of cook required. RICHI’s technical team recommended the Model RCYP200G Wet Process Whole Grain Expander.

This model cereal grain expansion machine was selected for its high output and robust design, suited to the scale of a large integrated farm:

• Type: Wet Process Whole Grain Expander
• Main Motor Power: 132 kW
• Screw Diameter: 200 mm
• Feeder Power: 1.5 kW
• Conditioner Power: 7.5 kW
• Conditioner Specification: DC420-3000 (A large conditioner essential for consistent moisture and heat addition to high-volume grain flow).
• Corn Output: 1.6-2.2 T/H (This capacity allowed them to process sufficient grain for a significant portion of their daily ration needs in a single, efficient shift).
• Barley Output: Estimated at 1.8-2.5 T/H (based on similar density and starch content).

The Strategic Role in an Integrated Feed System

This RICHI cereal grain expander is now the thermal processing core of their on-farm feed ingredient plant. Whole barley or corn is fed into the large preconditioner, where live steam is injected, hydrating and heating the grains.

This tempered grain then enters the expander barrel. Inside, the high-shear screws generate intense friction and pressure, further cooking the starch. Upon exiting through the die, the sudden pressure drop causes the superheated, plasticized grain to expand, creating a porous, low-density pellet or collet.

The expanded output is then cooled and can be used in two ways:

1. For Poultry Feed: The expanded barley or corn is cracked and mixed with protein concentrate, oils, and premixes to create a high-energy, highly digestible finisher feed. The expansion allows them to include higher levels of local barley, replacing more expensive wheat or imported corn.
2. For Dairy Cattle Feed: The expanded grains are used as a high-energy component in the total mixed ration (TMR). The improved starch availability supports higher milk yield and can lead to better rumen health compared to raw, finely ground grains.

This single cereal grain expansion machine in Iran allows the Iranian company to upgrade inexpensive local barley into a premium feed ingredient, directly reducing their reliance on purchased concentrates and improving the performance of their own livestock.

Shipping and Delivery: Navigating to the Iranian Plateau

The RCYP200G cereal grain expansion machine, along with its substantial conditioner and feeder, was manufactured and test-run. Due to its size, it was disassembled into major modules. All components were packed into multiple containers and shipped from Qingdao Port, China.

Given international sanctions and logistics complexities, the most common and reliable route for heavy machinery into Iran is via the Port of Bandar Abbas, Iran, on the Persian Gulf. This is Iran's primary major port. After customs clearance in Bandar Abbas, the containers were transported overland by truck to the client's facility in Fars Province, a journey of several hundred kilometres.

Technical Advantages: Engineered for Continuous, Tough Service

The selection of RICHI's cereal grain expansion machine in Iran was based on specific features that ensure reliability and cost-effectiveness in a demanding agricultural industrial setting:

• "One-Machine, Multiple Grains" Versatility: This was a key selling point. The ability to process both barley and corn—grains with different characteristics—by making minimal adjustments (primarily die selection and conditioner parameters) meant one machine could serve dual purposes, maximizing the return on their investment.
• Robust, Simplified Drive System: The unique gearbox design requiring no external cooling is a significant advantage. It eliminates the risk of cooling system failures (leaks, pump issues), reduces maintenance complexity, and is inherently more reliable, especially in the dusty environment of a feed mill.
• Superior Wear Resistance for Abrasive Materials: The use of special alloy steels for screws, barrel liners, and dies is critical. Whole grains, particularly barley with its silica-rich hull, are highly abrasive. This material choice extends component life dramatically, reducing downtime for replacements and keeping long-term operating costs predictable.
• Industrial-Grade Bearing and Lubrication System: The three-bearing support with circulating thin oil lubrication is a feature found on much larger, more expensive industrial extruders. It provides exceptional support for the long, high-torque screw, ensures perfect alignment, and offers far superior heat dissipation and contamination protection compared to grease-lubricated bearings. This is fundamental for achieving 24/7 operational reliability.
• Integrated Thermal and Chemical Processing: The machine is not just a puffer. It is a continuous hydrothermal cooker. It effectively pasteurizes the grain, denatures anti-nutritional factors, and structurally modifies the starch and protein—all processes that directly translate to improved feed conversion ratios (FCR) in their livestock.

Client Feedback from Fars Province, Iran

After a full production cycle, spanning both a poultry grow-out period and a dairy lactation cycle, the technical manager provided this assessment: "Investing in the RICHI cereal grain expansion machine was a strategic decision for our self-sufficiency.

It has fundamentally changed our feed formulation economics. We are now using significantly more of our local barley, and the expansion process has made it highly digestible for our broilers. The machine is built like a tank—it runs continuously during our processing days with no fuss. The gearbox and bearing system are particularly impressive.

For a single machine that allowed us to upgrade our core feed ingredients and reduce external dependency, this grain expansion system has delivered excellent performance and reliability for our integrated operation in Iran."

The RCYP Platform: Beyond Livestock Feed

While deployed as a cereal grain expansion machine in Iran for feed, the same robust platform has applications in other sectors:

• Production of expanded grains for breakfast cereals or snack bases.
• Pre-treatment of grains for the brewing industry (to improve extract yield).
• Processing of full-fat soybeans into a high-quality rumen-bypass protein for dairy cows.
• Manufacturing of pre-gelatinized flours for food applications.

This versatility provides potential for future diversification should the company's business model evolve.
