RICHI MACHINERY has completed shipment of an 8-ton-per-hour premix production line to southern Brazil, supporting regional feed manufacturers focused on high-precision livestock nutrition.

Premix products form the foundation of modern feed formulations, supplying essential vitamins, minerals, and trace elements that represent small inclusion rates but have outsized effects on animal health. Accurate dosing and homogeneous mixing are not optional—they are critical to both animal performance and production economics.

Project Background

Brazil ranks among the world’s leading producers of poultry, pork, and beef, with feed conversion efficiency driving competitiveness in export markets. As formulations become increasingly sophisticated—with specialty additives, enzymes, and precisely balanced trace minerals—demand for high-quality premix facilities continues to grow.

The customer, an established feed manufacturer supplying independent livestock producers, sought a compact yet precise premix system capable of supplying multiple downstream feed mills with consistent nutrient blends. Their existing operation relied on manual addition of micro-ingredients, a method that becomes impractical as product lines diversify and accuracy requirements tighten.

Technical Solution

RICHI provided a specialized premix line incorporating:

• Micro-ingredient storage bins sized for frequent batch changeovers
• High-accuracy weighing modules with electromagnetic force restoration load cells
• Horizontal ribbon mixer engineered for gentle but complete dispersion of fine powders
• Dust-free conveying system incorporating sealed transfers and centralized filtration
• Finished product packing unit with automated bag placement and sealing

The system achieves dosing accuracy within ±0.1 percent of target weight and mixing coefficient of variation below 5 percent—performance levels required for premix operations supplying commercial feed mills.

Special anti-segregation designs prevent separation of fine powders during discharge and transfer. This is particularly important in premix applications where particle size differences between ingredients can lead to stratification and inconsistent nutrient content from bag to bag.

Factory Acceptance and Shipment

Prior to shipment, RICHI conducted full factory acceptance testing witnessed by the customer’s technical staff. Verification included weighing accuracy across the full range of batch sizes, mixer performance through tracer studies, and electrical system stability under simulated operating conditions.

The equipment was packed into four containers and dispatched in January, with installation scheduled for early March. RICHI’s Brazilian service network will provide on-site support during mechanical assembly and control system integration.

Supporting Brazil’s Feed Industry

Once commissioned, the premix plant will supply multiple compound feed lines, enhancing nutritional consistency across livestock operations ranging from poultry integrations to independent swine producers.

This project highlights RICHI’s capability to deliver high-precision feed processing systems for advanced nutrition applications—equipment that operates at tighter tolerances than standard compound feed lines while maintaining the throughput required for commercial viability.

RICHI MACHINERY has completed shipment of a 4-ton-per-hour chicken manure organic fertilizer pellet production line to Upper Egypt. The equipment will serve poultry operations in the region looking for practical solutions to what has become a pressing environmental challenge: the disposal of accumulated poultry litter.

Addressing Poultry Waste Challenges

Egypt’s poultry sector has expanded considerably over the past decade, with large concentrated farms now operating throughout the Nile Valley. These operations produce substantial volumes of manure that, if stockpiled or improperly handled, can contaminate groundwater and generate ammonia emissions affecting local communities.

The customer, a diversified agricultural company with existing poultry operations, recognized an opportunity. Rather than treating manure as a disposal problem, they aimed to convert poultry litter into commercial organic fertilizer suitable for vegetable and fruit cultivation—crops that feature prominently in Upper Egyptian agriculture.

RICHI provided a turnkey solution integrating composting, granulation, and drying, covering the entire conversion process from raw manure to finished bagged product.

Process Design and Equipment Scope

The production line includes several integrated stages:

• Manure crushing system for breaking up compacted litter and removing larger aggregates
• Compost fermentation layout with windrow turning capability to accelerate biological stabilization
• Organic material grinder for consistent particle size reduction prior to pelleting
• Dual-shaft mixer for blending composted material with binders and optional nutrient additives
• Organic fertilizer pellet mill equipped with corrosion-resistant materials to handle the abrasive nature of manure-based feedstocks
• Rotary dryer to reduce moisture content to storage-stable levels
• Cooler and screener for temperature reduction and particle size classification
• Automatic bagging system for finished product

Designed output capacity is 4 tons per hour under continuous operation, though the system can run at reduced rates during initial commissioning while operators gain familiarity.

The fermentation stage is particularly critical. Proper composting eliminates pathogens and weed seeds while stabilizing the organic matter—essential steps for producing a product that meets agricultural safety standards. The pelletizing stage that follows transforms loose, dusty manure into uniform, easy-to-handle granules that flow through standard fertilizer application equipment.

Factory Acceptance and Logistics

All equipment underwent factory testing prior to shipment, with particular attention to the pellet mill’s performance on simulated organic feedstock. Seven containers were loaded and dispatched in January, with arrival expected at the customer’s site in mid-February.

RICHI will deploy field engineers to supervise on-site installation and commissioning once civil works are completed by the customer’s local contractors. Operator training will follow, focusing on fermentation management and pellet mill die selection for organic materials.

Agricultural Benefits

The finished fertilizer pellets will provide slow-release nutrients to local farms, improving soil structure through organic matter addition while reducing reliance on imported chemical fertilizers. For the customer, the project creates a new revenue stream from what was previously a cost center—waste disposal.

Osaka’s morning tofu production starts before dawn, the steam rising from cooking vats as soybeans transform into milk and then curds. By mid-morning, the okara—soy pulp—accumulates in bins, a byproduct that historically went to animal feed or disposal. Now some of it goes to cat litter.

Market Background

Japan’s pet market has evolved rapidly. Pet owners, particularly cat owners, seek products that are convenient, effective, and environmentally responsible. Traditional clay litter requires mining, produces dust, and fills landfills. Tofu-based litter offers an alternative: biodegradable, flushable, and made from a renewable resource.

The okara feedstock is abundant in Japan, where tofu consumption remains high. It’s food-grade material, clean and consistent, with properties that make it suitable for litter after processing.

Raw Material and Processing Challenges

Fresh okara contains 70 to 80 percent moisture—far too wet for direct pelleting. It spoils quickly without preservation. And its protein and fiber content affect how it absorbs moisture and controls odor.

The process must address all these factors. Drying reduces moisture to pelletizing range. Additives control odor and improve absorption. And the pellet mill must form durable pellets without over-compressing the material—over-compression reduces absorbency and makes pellets too hard for cats to cover.

Production Line Design

The Osaka line incorporates lessons from previous installations:

• Raw material receiving and pre-mixing with additives and preservatives
• Hammer mill for particle size adjustment
• Rotary dryer with temperature control to prevent protein degradation
• Pellet mill with specialized die for soft-but-durable pellets
• Counterflow cooler for gentle temperature reduction
• Screening system for fines removal
• Automatic bagging with dust control

The cat litter pellet machine uses dies with compression ratios specific to soy-based materials—different from paper or wood because the protein and fiber content affect binding.

Installation and Timeline

Mechanical assembly at the Osaka site is complete. Electrical integration continues, with commissioning scheduled for March. The customer plans initial production focused on the domestic Japanese market, where tofu litter commands premium prices.

Environmental and Market Benefits

For the tofu manufacturers supplying okara, the plant provides a disposal channel for a material that has low value. For the litter producer, it creates a product with growing demand. For Japanese cat owners, it offers a litter option that reduces environmental impact compared to clay.

For RICHI, the project demonstrates adaptation to yet another specialized feedstock—the kind of application-specific engineering that distinguishes the company from competitors offering standardized solutions.

RICHI MACHINERY has successfully commissioned a 6 T/H cow manure organic fertilizer production line in the Netherlands, providing sustainable solutions for dairy farms and crop producers.

The installation sits in Chiang Rai province, near the Myanmar border, where bamboo grows on hillsides that are too steep for rice paddies. The plant owner had been selling raw poles to construction and furniture makers, but the residues—tops, branches, processing waste—accumulated in piles that occasionally caught fire during the dry season.

Market Background

Thailand’s bamboo resource is substantial but underutilized. The country has millions of hectares of bamboo forest, both natural and planted, generating continuous biomass as stands are harvested on rotation. Most of it goes to low-value uses or simply decomposes.

Pelletizing changes the economics. Bamboo pellets burn hot—calorific value around 4,500 kcal/kg, comparable to wood—with low ash and minimal sulfur. Industrial users in Thailand and neighboring countries will buy all that can be produced, at prices that justify processing.

Raw Material and Process Design

Bamboo’s structure presents challenges. The stems are hollow, with dense nodes and fibrous walls. The silica content, absorbed from soil during growth, accelerates wear on cutting surfaces. And the moisture distribution is uneven—green bamboo can exceed 50 percent moisture in the stems while leaves are much drier.

The process must handle all of it. Pre-chopping reduces whole stems to manageable pieces. Hammer milling further reduces particle size while knocking loose the silica that would otherwise embed in pellet dies. Drying brings moisture below 12 percent regardless of starting point. Then pelletizing compresses the fiber into dense cylinders.

Equipment Configuration

The Chiang Rai line comprises:

• Bamboo pre-chopper and conveyor system with heavy-duty knives
• Hammer mill with screens sized for bamboo fiber
• Rotary dryer with thermal efficiency optimized for biomass
• MZLH series bamboo pellet machine with wear-resistant die materials
• Counterflow cooler for pellet stabilization
• Screening system for fines removal
• Bagging and palletizing unit for finished product

The pellet mill uses chrome-molybdenum dies with increased wall thickness in wear zones. Rollers are surfaced with tungsten carbide for extended life. Even with these measures, the operator expects to replace dies every 800 to 1,000 hours—shorter intervals than for wood, but acceptable given the feedstock cost.

Installation and Commissioning

Mechanical installation finished in January, ahead of the dry season when construction access is easiest. Electrical integration continues, with commissioning scheduled for March. The customer plans initial operation at 5 tons per hour, ramping to full capacity as the supply chain stabilizes.

Environmental and Economic Benefits

For the plant owner, the line converts a waste disposal problem into a revenue stream. For local bamboo growers, it creates a market for material that previously had no value. For Thailand’s renewable energy targets, it supplies fuel that displaces imported coal.
