12–13 T/H Chicken Feed Manufacturing Plant in Kenya

RICHI MACHINERY

Why the Project Stopped at Mash Feed

The first engineering discussion took place in February 2025, but the customer was not initially planning a complete factory. The immediate problem was purchased-feed cost. A mixer looked like the cheapest answer until the team mapped what had to happen before and after mixing: corn still needed controlled grinding, bulk ingredients had to be weighed repeatably, soybean meal and bran needed clean storage, and finished feed still had to be packed at commercial speed.

The buyer also had to decide whether the factory should be designed mainly for internal farm demand or for wider commercial sales. Internal demand favored simplicity and predictable daily output, while outside sales required more attention to bag presentation, batch records and the ability to change between broiler and layer formulas without long downtime. The final concept keeps enough flexibility for both.

The client first asked about reducing feed cost with a smaller animal feed manufacturing plant concept. Once the 30,000 T/Y requirement was put against the one-shift schedule, the project moved from a mixer purchase to a complete mash-feed line.

The design question became: how much of a feed factory is actually necessary when the final product will remain mash?

The answer was deliberately narrow. Corn is cleaned, stored and ground; bulk ingredients are weighed and mixed; finished mash goes directly to packing. There is no pellet press, cooler, crumble unit or boiler to maintain. This kept the plant suitable for a farm-linked poultry business that needed consistent feed every day but did not need the extra capital and utility load of pelleting.

By early March, the customer had accepted the full mash-feed process instead of a standalone mixer. The final engineering package kept automation where it directly improved consistency—batch weighing, material transfer and bagging—while avoiding unnecessary process stages.

The equipment and engineering contract was finalized in May 2025.

The Numbers Behind the 30,000 T/Y Factory

RICHI MACHINERY

The Site Was Planned Around Truck Separation

The first layout concept placed most equipment on one level. On a 4,500 m² property, that left too little separation between receiving traffic, material preparation and finished-feed loading. The final plan uses a partial vertical arrangement and selected below-grade positions so gravity can assist material movement without turning the building into a tall industrial tower.

The change was driven by logistics, not appearance.

Raw materials enter from one side of the site, processing sits between receiving and dispatch, and the finished-feed warehouse is positioned so outbound trucks do not have to cross the main unloading path. This shortened internal travel and reduced congestion during the one-shift production window. The finished-product area was kept large enough to buffer packed feed between production and truck collection, but not so large that working capital would be tied up in weeks of inventory. Corn storage receives the opposite treatment: two 500 T silos give the plant a meaningful grain buffer because corn is the dominant ingredient and the material most exposed to seasonal price and moisture changes.

Building Distribution

The material route is organized from south toward the west side of the property:

• Raw-material intake and corn-silo access on the south side
• Grinding, weighing and mixing concentrated in the southwest production zone
• Packed finished feed transferred west into the dispatch warehouse

This zoning gives the customer a practical advantage at only 10 employees: fewer forklift conflicts and less time spent moving bags between unrelated parts of the site.

Bulk Ingredients Are Local but Supply Quality Still Moves

The feed program is built around corn, soybean meal and wheat bran, three materials that fit a Kenya chicken feed production line but do not arrive with identical density, moisture or nutrient quality. The customer therefore buys from more than one nearby farm or trader and checks incoming lots before they enter long-term storage.

Corn receives the closest physical control because it accounts for half of the listed annual bulk-material basis and must pass through the hammer-mill section. Soybean meal and wheat bran are stored separately so their flow and dosing can be managed independently rather than blended before weighing.

Major Bulk Inputs and Utility Basis

The three listed bulk ingredients total 30,000 T/Y and form the mass-balance basis for the plant. Premix, calcium, salt, amino acids and other low-inclusion ingredients are handled through the batching system but are not assigned separate annual tonnages here. Corn moisture is checked by supplier lot; wetter batches are segregated or blended with drier grain before grinding rather than adding a dedicated dryer to a mash-only process. Quality control therefore begins before milling. Incoming corn should be checked for moisture, visible mold, odor and contamination, with suspicious lots isolated rather than blended into the main silo. For a poultry-feed business, aflatoxin and other mycotoxin risk can turn a cheap grain purchase into an expensive flock problem. Soybean meal also needs supplier and protein consistency checks because a change in protein quality cannot be corrected by grinding or longer mixing.

Nine Main Machines Cover the Core Production Duty

Unlike an animal feed pellet plant, this Kenya project does not need a conditioner, pellet mill, cooler or crumble section. The equipment package is built around the steps that actually add value to mash feed: stable grain grinding, repeatable mixing, short conveying routes and controlled packing.

That process boundary is also why US$180,000 can cover the main feed-production equipment even though the completed new-build project has a much higher total fixed investment.

Core Equipment Configuration

The core list contains nine major machines or storage/transfer units. Batch weighing controls and the two bag filters are treated as supporting systems rather than counted again in this table.

Two hammer mills give the 12–13 T/H line more operating margin than one oversized grinder. They can share corn-grinding duty during peak production, while maintenance on one unit does not automatically stop the mixer and packing section. The mixer is sized so its batch volume and cycle time can keep pace with the required 12.5 T/H average rather than forcing the whole factory to wait on mixing. The line also benefits from separating grinding capacity from mixing capacity. Corn grinding can be scheduled ahead into a short buffer when both hammer mills are available, while the mixer runs on a steady batch rhythm. That reduces the chance that a screen change or hammer inspection immediately starves the downstream process. For a small team, this kind of operational buffer is often more useful than adding another major machine.

Five Steps From Grain Intake to Finished Mash

The Kenya poultry mash feed line is intentionally short. Fewer process stages reduce maintenance and electricity demand, but they also make grinding and mixing quality more visible because there is no pelleting step to mask an uneven meal.

Operating Sequence

1. Corn Intake & Storage
   • Corn arrives by truck and is checked before unloading into the receiving route
   • Bucket elevators transfer accepted grain into the two 500 T silos for production buffering
2. Protein Meal and Bran Storage
   • Soybean meal and wheat bran remain separated in the raw-material area to prevent uncontrolled premixing
   • Bagged ingredients are opened at the designated feeding point according to the active formula
3. Controlled Corn Grinding
   • The two hammer mills reduce corn to the particle profile required for broiler or layer mash
   • Enclosed transfer and local aspiration keep grinding dust inside the collection system
4. Batching & Mixing
   • Major ingredients and low-inclusion components are weighed before mixer charging
   • Mixing time is set from uniformity checks rather than shortened only to increase hourly tonnage
5. Finished Mash Packing
   • The automatic bagging system receives mash directly after the final transfer and quality check
   • Finished feed is packed mainly in 25–50 kg bags for farm use and local distribution

There is no pellet diameter to specify because the finished product is mash feed. Instead, product control focuses on ground-particle distribution and mix uniformity. Broiler starter formulas use a finer, more even meal than layer feeds with coarser mineral fractions. During commissioning, mixer cycle time was increased until ingredient distribution met the plant’s routine quality target. The same equipment can make several mash-feed specifications by changing grind profile and formula rather than by changing downstream machinery. Broiler starter feed normally needs a more uniform fine fraction for young birds, grower and finisher mash can use a slightly coarser structure, and layer feed may include a deliberately coarser calcium fraction. The mixer and batching system therefore do more of the product differentiation work that a die and crumble section would perform in a pelleted-feed plant.

Dust Control Follows the Two Grinding Points

Environmental investment is about US$25,000, with the main attention on dust rather than wastewater or boiler emissions. Because the plant has no dryer and no steam boiler, the highest routine particulate loads come from corn grinding and dry-material transfer. Dust control also protects product quality. Fine corn and bran dust that settles on beams, motors or bagging areas can become a source of cross-contamination and housekeeping problems. The two-filter arrangement is therefore linked to the two grinding routes and the main transfer points rather than installed as one distant central collector with long ducts and weak pickup at the actual dust source.

Air-Handling Arrangement

• Two bag-filter systems are installed around the main grinding and transfer dust sources
• Design collection efficiency is approximately 99% when filters and ducting are maintained correctly
• Exhaust stacks extend to about 15 m to discharge treated air above the working zone

Treated Dust Design Data

Workshop enclosure, routine sweeping, filter inspection and keeping spilled mash away from motors and bearings are part of the same dust-control plan. The project does not rely on the bag filters alone. Because the site handles dry grain and powder, fire prevention is managed together with dust control. Electrical motors and bearings are kept free of settled dust, hot work is separated from production periods, and the bag filters are inspected for damaged elements that could reduce capture efficiency. These are simple controls, but they are especially important in a compact mash-feed factory where grinding and storage sit close to one another.

Mash Feed Keeps the Utility Load Manageable

No steam system and no thermal dryer are required. Water is used mainly for staff, cleaning and fire-protection support rather than as a process ingredient. Electricity is concentrated in the two hammer mills, mixer, elevators, dust collectors and bagging system, which is why the annual power basis is materially higher than a small office-type load but still well below a comparable pelleted-feed factory.

US$180,000 of Equipment Inside a US$720,000 New Build

• Main mash-feed equipment package: approximately US$180,000
• Equipment shipped from Qingdao Port with the packing list coordinated to the installation sequence
• Arrival port: Port of Mombasa, Kenya, followed by inland transport to the project site

The completed project fixed investment is approximately US$720,000. The difference between equipment cost and total fixed investment covers the 2,000 m² building program, foundations, two corn silos, electrical distribution, environmental systems, freight and inland handling, installation, commissioning and other site infrastructure. Mechanical installation took about three weeks after the site was ready. Civil and site spending is substantial because this is a new-build case, not a machinery-only retrofit. A buyer comparing quotations should therefore separate machine price from the cost of foundations, steel structure, storage, site roads, drainage, electrical connection, fire protection and labor accommodation. Using the US$180,000 equipment number as the total project budget would materially understate the capital required to reproduce the same operating conditions.

Why Mash Feed Fits This Kenya Poultry Business

The commercial logic is tied to feed cost and supply control rather than to selling a premium pellet. Kenya’s poultry sector uses corn-based rations and faces pressure from corn and soybean-meal availability, so a farm-linked mill can create value by purchasing ingredients directly, controlling formulation and avoiding dependence on finished-feed deliveries. In search and buyer terms, the same project can serve as a broiler feed manufacturing plant in Kenya, a layer feed production line in Kenya, or a chicken mash feed plant in Kenya because the common front end can switch formulas without adding pelleting equipment. Recent Kenyan poultry-market reporting also shows why this matters commercially: feed remains one of the largest cost pressures in chicken production, while corn and soybean-meal availability can tighten ingredient supply. A plant of this size does not remove commodity-price risk, but it gives the owner more control over purchasing timing, formulation choices and the margin that would otherwise sit inside purchased finished feed.

For this customer, the deciding question was whether pelleting would add enough value to justify more equipment, steam, power and maintenance. The answer was no for the first stage of the project.

Running a chicken poultry feed manufacturing plant as a mash-feed factory gives the business three immediate controls:

• Formula control by poultry stage instead of accepting one supplier’s standard feed specification
• Lower exposure to finished-feed transport and supplier margin when raw materials can be bought directly
• More reliable feed availability for the owner’s broiler and layer operations during supplier shortages

Mash feed also leaves a clear expansion path. If future buyers begin requiring pellets or crumble, pelleting can be added as a separate downstream project once sales volume justifies the steam, cooler, pellet mill and extra electrical load. That staged approach is also safer for capital planning. The current plant can first prove its raw-material supply, poultry demand and one-shift utilization. A future pellet section can then be sized from actual sales data instead of being purchased in advance and left underused. Space and electrical interfaces should be reserved where practical, but the first-stage business does not need to carry the full cost from day one.

Do Not Add Pelleting Until the Market Pays for It

This is not an oversized chicken feed mill plant. It is a 30,000 T/Y factory built around one shift, ten people and a product form the customer can use immediately.

That simplicity is part of the engineering result, not a missing feature.

The 12–13 T/H capacity closes the annual production target without paying for a large margin of unused throughput. Two hammer mills protect grinding availability, one properly sized mixer sets batch rhythm, and a single automatic packing line is enough for the one-shift dispatch plan.

For buyers comparing a 12–13 T/H chicken feed manufacturing plant in Kenya, the first design decision should be product form before machine model:

• Which broiler and layer formulas will be produced, and how much of each is needed per year?
• Can corn, soybean meal, bran and micro-ingredients be sourced consistently enough to keep the line working through the full year?
• Will customers accept mash feed, or is there a confirmed commercial reason to add pellets or crumble?

Once those answers are fixed, RICHI can size grinding, batching, mixing, storage and packing around the real annual schedule instead of adding equipment that the business does not yet need. For a useful quotation, the buyer should also provide daily feed demand by bird stage, expected bag size, corn moisture range, available power supply, site dimensions and whether micro-ingredients will be dosed manually or automatically. Those details affect hammer-mill duty, mixer batch size, storage turnover, bagging speed, dust extraction and staffing far more than a simple request for a 12 T/H or 15 T/H line.
