Feed Plant for Mash and Pellet Feed Production in Uganda

RICHI MACHINERY

Why Uganda?

Uganda’s livestock sector is growing but still has significant unmet demand for quality feed. Key drivers:

Current market situation:

• Annual compound feed production: Estimated at 300,000-400,000 tons (formal sector). On-farm mixing adds another 200,000 tons.
• Import dependency: Many feed ingredients (soybean meal, premix, some corn) are imported from Kenya, Tanzania, and China.
• Price: Commercial feed ranges from 2,500-3,500 UGX/kg ($0.68-0.95) depending on type and quality.
• Quality issues: Inconsistent quality from small mills is a major complaint. The client’s own experience with delayed deliveries and variable pellet durability motivated them to build their own mill.

The client’s target market:

The client’s breakeven point is 12,000 tons/year (60% capacity). They have already secured off-take agreements with several large poultry farms in Mukono and Kampala.

The Site and Building 

The client’s facility is located on a former agricultural research station site in Mukono District. The site was leased from the Mukono District local government. The key advantage was an existing 2,000m² steel-framed building with 8m ceiling height – perfect for feed production with some modifications.

Site layout:

Production building layout (single story, 2,000m²):

The client originally wanted a multi-story gravity-flow design, but the existing building was single story. RICHI designed a single-story layout with bucket elevators and conveyors to move material between equipment.

The client’s key requirement: The line must produce both mash feed (no pelleting) and pelleted feed. Mash feed bypasses the pellet mill, cooler, and screener – going directly from the mixer to the finished bins. The layout accommodates this with a diverter after the mixer.

Equipment Configuration

The client chose RICHI’s equipment configured for a flexible 8 t/h line (expanding to 8 t/h with future upgrades). N

Major equipment :

Equipment cost (FOB Qingdao): $185,000 USD

Why this configuration for a flexible feed plant:

1. Hammer mills + micro-grinding mills. The client processes corn, wheat, and other grains. For poultry feed, the standard hammer mill (3mm screen) is sufficient. For fish feed (tilapia), the client uses the micro-grinding mill (1-1.5mm screen) for finer particles. Having dedicated mills for different tasks reduces downtime for screen changes.

2. Separate mash and pellet routes. After the mixer, a diverter sends material either:

• Directly to finished bins (mash feed) – bypassing the pellet mill, cooler, and screener.
• To the pellet mill for pelleting (pelleted feed).

This allows the client to produce both product types without stopping production.

3. Biomass boiler (2 t/h). The client chose a biomass boiler (fueled by rice husks or wood pellets) instead of diesel or electric because:

• Biomass fuel is cheaper in Uganda (about 400 UGX/kg ≈ $0.11)
• Diesel is expensive (4,500 UGX/liter ≈ $1.22)
• The client has access to rice husks from local rice mills

4. Counterflow cooler. The pellet cooler machine is essential for pelleted feed (hot pellets must be cooled to <40°C before bagging to prevent mold). The client also uses the cooler for some mash feed (cooling is not required for mash, but the cooler is bypassed when producing mash).

Raw Materials

The client produces feed for poultry (broilers and layers), pigs (growers and finishers), and fish (tilapia). The formulations vary, but the core ingredients are:

Annual raw material consumption:

Corrected raw material consumption (approximate, for 20,000 tons of feed):

Raw material quality control:

The client has an incoming inspection process:

1. Visual inspection for mold and insects – any load with visible mold is rejected.
2. Moisture testing – corn must be <14% moisture; if higher, the client negotiates a discount or rejects.
3. Cleaning before use – all grains pass through a rotary screener and magnetic separator to remove stones, dust, and metal.
4. Two intake points – one for grains needing grinding, one for powders like salt and premix that don’t need grinding.

Process Flow

This animal feed production line can produce both mash and pellet feed. The flow splits after the mixer. This is a key design feature for the Ugandan market where farmers want both options.

Overview: Two Production Routes

Step 1: Raw Material Intake and Cleaning

The client uses two separate intake lines:

Intake Line I (for corn, wheat, rapeseed):

• Workers open bags and dump into the hopper (with grate to catch large debris).
• Drag chain conveyor moves material to a bucket elevator.
• Material lifted to the rotary screenerto remove stones, dust, and oversized material.
• Material passes through a magnetic separator to remove ferrous metal.
• Cleaned material goes to the hammer mills.

Intake Line II (for rice bran, salt, premix):

• Similar process, but uses a powder screener instead of a rotary screener.
• Powdered materials go directly to the batching bins (no grinding needed).

Step 2: Grinding (Hammer Milling and Micro-grinding)

Particle size matters. Poultry feed needs 800-1,200 microns; fish feed needs 300-500 microns.

Corn, wheat, and rapeseed from the intake go to the hammer mills. The client uses different mills for different particle sizes:

• Standard hammer mills (SFSP132*50): For poultry and pig feed. Screen size: 3mm. Output particle size: 800-1,200 microns.
• Micro-grinding mills (SWFP66×80): For fish feed (tilapia). Screen size: 1.5mm. Output particle size: 300-500 microns.

Hammer mill parameters (each):

Step 3: Batching

Ground material is lifted to the ingredient bins (20 bins total) by bucket elevators.

Bin configuration:

Batching system (computer-controlled):

The client uses two batching scales:

• Large scale: 1,500 kg/batch – for major ingredients (corn, soybean meal)
• Small scale: 1,000 kg/batch – for minor ingredients (rice bran, premix)

Batching sequence (per batch):

Accuracy: ±0.1% for major ingredients, ±0.5% for micro ingredients.

Step 4: Mixing

The batch drops into the twin-shaft paddle mixer.

Mixer parameters:

After mixing, the flow splits:

• For mash feed: Material goes directly to the finished bins.
• For pelleted feed: Material goes to the pellet mill.

Step 5: Pelleting (Only for Pelleted Feed)

Steam is critical for pellet quality. The client’s biomass boiler provides steam at 150°C, which drops to 85-95°C in the conditioner.

Conditioning:

Material from the mixer drops into the one layer conditioner where steam from the 2 t/h biomass boiler is injected.

Conditioning parameters:

Animal feed pellet press:

The client has interchangeable dies:

• 3mm die: Broiler starter/finisher
• 4mm die: Pig grower/finisher
• 2mm die: Tilapia grower

Step 6: Cooling and Crumbling

Hot pellets (70-85°C) drop into the counterflow cooler.

Cooler parameters:

• Type: Counterflow
• Fan: 4-72-11No8c
• Retention time: 10-15 minutes
• Outlet temperature: ambient + 3-5°C (28-32°C in Uganda)

Crumbling (for chick starter and small fish feed): If the product needs to be crumbled (broken into smaller pieces), the pellets go through the roller crumbler.

Step 7: Screening

For pelleted feed: Pellets pass through a rotary screener to remove fines and oversize.

• Top deck (6mm): rejects oversize (returns to pellet mill)
• Middle deck (3mm): retains acceptable pellets
• Bottom deck (2mm): removes fines (returns to mixer)

For mash feed: Powder passes through a vibrating screener to remove agglomerates (lumps).

Step 8: Packaging

Finished product is stored in three finished bins, then packaged.

Packaging equipment:

Packaging process:

1. Operator hangs a 25kg or 50kg woven poly bag on the filling spout.
2. Scale fills automatically (accuracy ±100g for 25kg bags).
3. Bag is sewn closed and conveyed to palletizing area.
4. Bags are stacked on pallets (40 × 25kg = 1,000kg/pallet).

Utilities and Consumption

Water balance:

Important note: The client’s boiler water is recycled (condensate return). Only 10-20% is fresh make-up. “steam 4,800 m³” is the steam generated, not fresh water consumed.

How RICHI Customized This Line for Mash and Pellet Production

The client had specific requirements that shaped the equipment design:

Requirement 1: The client needs to produce both mash feed (powder) and pelleted feed. Many farmers in Uganda prefer mash feed because it’s cheaper (no pelleting cost). But commercial farms want pellets.

RICHI solution: Designed the line with a diverter after the mixer. The diverter sends material either:

• Directly to the finished bins (mash feed) – bypassing the pellet mill, cooler, and screener.
• To the pellet mill for pelleting (pelleted feed).
  This allows the client to produce both product types without stopping production or reconfiguring the line.

Requirement 2: The client has a single-story building (no gravity flow). The original building was a steel-framed structure with 8m ceiling height – adequate for equipment but not tall enough for a multi-story gravity-flow design.

RICHI solution: Designed a single-story layout with bucket elevators at key points:

• Elevator 1: Intake to screener and hammer mills
• Elevator 2: Grinding to ingredient bins
• Elevator 3: Mixer to pellet mill (or directly to finished bins for mash feed)
• Elevator 4: Cooler to screener and finished bins
  The layout uses 5 bucket elevators total (TDTG36/28 and TDTGQ series).

Requirement 3: The client needs fine grinding for fish feed (tilapia). Tilapia feed requires particle sizes of 300-500 microns – too fine for standard hammer mills.

RICHI solution: Included a micro-grinding mill dedicated to fish feed production. The mill uses a 1.5mm screen and high rotor speed (4,500 RPM). The client runs the micro-grinding mill once per week to produce a month’s worth of fish feed base.

Requirement 4: The client has no municipal sewage connection. The facility is in a rural area.

RICHI solution: Recommended a package sewage treatment plant for domestic wastewater. The treated water is used for landscaping (the client’s site has a small garden). No discharge to surface water.

Requirement 5: The client has limited technical staff (15 employees, 8 production workers). Their workers are experienced but not professional complete feed mill plant operators.

RICHI solution: Provided a 3-week on-site training program:

• Week 1: Basic safety, machine startup/shutdown, daily checks (screens, magnets, lubrication)
• Week 2: Adjusting the hammer mill screens, changing dies on the pellet mill, troubleshooting common problems (overloads, blockages)
• Week 3: Computer batching system operation, batching accuracy checks, record keeping

The client’s lead operator (a former mechanic at a local grain mill) became proficient within 4 weeks.

Product Specifications

The client’s feed products meet Uganda National Bureau of Standards (UNBS) specifications for compound feed.

Product portfolio:

The total is 12,000 tons, not 20,000. The product list adds up to about 12,000 tons. The remaining 8,000 tons are probably custom formulations or bulk sales to other mills. The client’s design capacity is 20,000 tons, but actual production is ramping up.

Market Outlook for Compound Feed in Uganda

Uganda’s feed industry is growing. Key drivers:

1. Rising meat and egg consumption. Uganda’s per capita meat consumption is about 12 kg/year (vs 30-40 kg in developed countries). Growth potential is significant.

2. Government support. The Uganda National Development Plan III (2020-2025) targets livestock sector growth. The government offers tax exemptions for feed milling equipment (VAT exempt, import duty reduced).

3. Import substitution. Locally produced feed is 15-25% cheaper than imported feed (mainly from Kenya and China). The client’s import substitution advantage is significant.

4. Aquaculture growth. Tilapia farming is expanding in Central Uganda (Mukono, Kampala, Jinja). Fish feed (sinking pellets) is a growing segment. The client’s micro-grinding mill and 2mm die for the pellet mill allow them to produce high-quality tilapia feed.

Competition: There are 20-30 larger feed mills in Uganda (2,000-10,000 tons/year). The client’s 20,000 tons/year capacity puts them in the top tier. Smaller mills (500-1,000 tons) are common but have higher production costs per ton.

Challenges the client is managing:

The client’s breakeven point is 12,000 tons/year (60% capacity). At full capacity (20,000 tons/year), operating margin is about 15-20%. Payback on equipment ($185,000) is about 2 years.

Why an 8t/h Feed Plant Makes Sense in Uganda

Uganda has a growing livestock sector, abundant raw materials (corn, rice bran, soybeans), and a government supportive of agribusiness. Here’s why you should consider this market:

The economics work. A 20,000-ton/year feed mill in Uganda can generate $500,000-1,000,000 in annual profit at current prices. Payback is 18-24 months.

Raw materials are available. Uganda produces 3-4 million tons of corn annually. Rice bran is available from rice mills in eastern Uganda. Local soybean processing is expanding.

Demand is growing. Poultry and pig farming are expanding to meet urban demand. Fish farming is taking off.

Entry barriers are moderate. Import duties on feed milling equipment are reduced (0% VAT, 10% import duty). Financing is available from local banks (20-25% interest rates).

If you’re considering a commercial feed mill in Uganda, RICHI can help. We’ve designed lines for mash feed, pellet feed, and multi-species production. We understand the local conditions (rural locations, lack of natural gas, preference for mash feed).
