12–13 T/H Premix Feed Production Line in Brazil

RICHI MACHINERY

The Expansion Was About Product Control Not More Bulk Feed

When the project started in March 2025, the customer was already operating a sizeable animal nutrition business. The question was whether premix could be added without interrupting the core compound-feed operation or rebuilding the entire factory. That immediately shifted the discussion away from equipment quantity and toward segregation, batching accuracy, access, cleaning and how the new lines would connect to the existing electrical and warehouse systems.

The practical decision was to add premix as a dedicated production zone inside the existing feed mill, with its own ingredient receiving, weighing, mixing, dust control and packing route.

This mattered because the customer already had the downstream market and bulk-feed infrastructure. The investment only needed to create the missing capability: a controlled premix feed plant in Brazil that could serve poultry and cattle customers without compromising the existing products.

The client operates a mid-sized animal feed mill plant in central Brazil. Before the premix expansion, the site was already handling:

• About 120,000 T/Y of compound feed for poultry and livestock customers
• About 80,000 T/Y of concentrated feed produced and packed through the existing mill

The commercial case for the expansion came from two existing pressures:

1. Customers were asking for more precise vitamin, mineral and trace-element products instead of buying only finished compound feed.
2. The company wanted to move into a higher-value product category without duplicating the entire grain receiving, pelleting and warehouse infrastructure.

By May 2025, the two-line concept and retrofit layout had been confirmed. The contract followed in June, and equipment manufacturing began with the expansion planned around the existing operating schedule rather than around a greenfield construction sequence.

The Existing Site Dictated the Premix Layout

The animal feed processing plant was already in daily production, so every new conveyor, bin, mixer and packing point had to fit around live operations. The site area is about 6,172 m². The internal floor areas assigned to production, warehousing, office and staff functions total far more than the site footprint, so these figures are treated as combined floor area across the existing built space rather than as separate land footprints.

Existing Production Base

Site and Operating Basis

• Site area: about 6,172 m²
• Existing workforce: 20 employees across production, warehouse, maintenance, quality and administration
• Working schedule:
  • One production shift per day for the premix expansion
  • 8 scheduled hours per shift
  • 300 operating days per year

Combined Internal Floor Areas

For premix, the most important layout issue was not total floor area but separation. Fine mineral and vitamin powders needed a controlled zone away from bulk-feed dust, while finished premix needed a short, enclosed route from mixer discharge to packing. Existing columns and height restrictions also limited where elevators and transfer points could be placed. The expansion therefore had to use the existing building volume more intelligently rather than simply occupy more floor space. Ingredient access, cleaning clearance around mixers, bag movement, forklift traffic and dust-collector maintenance all had to remain workable while the adjacent compound-feed plant continued operating.

Why the Customer Chose Premix as the Next Product Step

The expansion was not a generic diversification exercise. It used customers the company already served and added a product category that depends more on formulation control than on bulk processing capacity.

Brazil’s poultry and cattle sectors create a practical market for nutrition products that can be dosed into farm or feed-mill rations. For this customer, the relevant demand centered on three things:

• Customized vitamin and mineral premix for poultry and cattle formulas
• Stable trace-element dosing with better batch-to-batch repeatability
• Uniform vitamin distribution without segregation during conveying and packing

The customer already had sales access to farms and feed buyers. The process gap was technical rather than commercial:

• Separate handling for low-inclusion and high-concentration ingredients
• High-precision batch weighing and mixing with documented sequence control
• A cleaner packing environment with less carryover from conventional feed production

That is the role of this livestock premix production line in Brazil: it adds precision manufacturing to an existing high-volume feed business instead of adding another grain-to-pellet line.

The Formula Is Mostly Powder but the Materials Do Not Behave the Same

Premix capacity is easy to misunderstand because the ingredients arrive already fine. There is little heavy size reduction, but the plant still has to control density differences, flowability, electrostatic dust, low-dose accuracy and the point at which liquid ingredients enter the batch. A light carrier can separate from a dense mineral during transfer even when both were correctly weighed, and a liquid added too early can create localized agglomerates that later affect discharge. For that reason, the real production limit is often the batch cycle, cleaning requirement and transfer stability rather than the nominal motor power of the mixer.

In this premix feed mill, rice husk powder and zeolite act mainly as carriers and bulk-building materials, while dicalcium phosphate, limestone, minerals, trace elements and vitamin premix create the nutritional matrix. Liquid lysine is added through a controlled spray route during mixing rather than being poured into the batch manually.

Annual Formulation and Procurement Basis

Annual mass-balance note:
The listed ingredient basis totals about 30,052 T/Y, which is close to the 30,000 T/Y finished-product plan. The small difference is consistent with rounded procurement and formulation figures. More important than that variance is the loading sequence: dense mineral powders and lighter carriers need enough mixing time and the correct order of addition to prevent segregation. The customer also needs to manage ingredient identity and lot traceability because a dosing error in a concentrated premix is more consequential than the same mass error in a bulk feed formula. Receiving labels, bin assignment, batch records and finished-product identification therefore form part of the process control, not just the quality department’s paperwork.

The Process Is Short but the Control Points Are Not

This is a non-pelletizing premix system, so it is fundamentally different from standard feed pellet production lines. There is no conditioning, pelleting, cooling or steam system. The manufacturing value is created by weighing accuracy, mixing sequence, dust containment, liquid distribution, clean transfer and batch traceability.

Two Parallel Lines Follow the Same Controlled Route

1. Dosing & Weighing
   • Macro carriers and minerals are weighed on the main dosing system
   • Trace elements and vitamin components use tighter weighing tolerances and controlled addition points
2. Batching
   • Powder ingredients enter the batch in a sequence chosen to limit segregation and bridging
   • Feeding rate is stabilized before mixer charging so light and dense powders do not arrive as separate slugs
3. Mixing
   • Each line uses its own double-shaft premix mixer machine for independent production and cleaning
   • Mixing time is set by formula density differences and uniformity checks rather than one universal timer value
4. Liquid Addition
   • Liquid lysine enters during the mixing phase after the dry carrier bed is established
   • A controlled spray pattern prevents local wet spots and reduces the risk of agglomeration
5. Discharge to Finished Bin
   • Finished premix discharges to dedicated finished-product bins with minimal intermediate handling
   • Enclosed transfer reduces dust and helps separate premix from the conventional feed area
6. Packaging
   • Automatic weighing controls the final pack quantity according to the sales specification
   • Bags are closed through the dedicated packing and sewing route
   • Finished batches are identified and held for dispatch under the plant’s traceability system

Two 6–7 T/H Lines Give More Than Capacity

The completed animal feed premix plant in Brazil uses two identical lines instead of one 12–13 T/H mixer train. Each line carries roughly half of the production duty, allowing one side to be cleaned, inspected or changed over while the other remains available for production. This also gives the operator more scheduling options: poultry premix and cattle premix can be grouped into separate production campaigns when their formulas or additive profiles differ, reducing the number of full-system changeovers. If one packing scale, mixer or elevator is stopped for maintenance, the second line can still support limited production instead of shutting the entire premix department.

Main Equipment in the Premix Expansion

Why two mixers matter:
Redundancy is useful, but contamination control is just as important. A two-line arrangement makes it easier to dedicate production campaigns, shorten cleaning windows and avoid turning every formula change into a complete plant shutdown. For a poultry premix feed production line in Brazil or a cattle premix feed plant in Brazil, that operating flexibility can be more valuable than one oversized mixer.

Utilities Are Simpler Than Pelleting but Cleanliness Uses Power Too

• The premix expansion is tied into the existing plant electrical distribution rather than using a separate utility building
• Site-wide annual electricity consumption after expansion is about 3.3 million kWh, covering the existing feed mill as well as the new premix section
• No steam, boiler or thermal conditioning system is required for premix manufacture

The premix section itself uses power mainly for mixers, elevators, dust collectors, feeders and packing equipment. Water demand is limited to sanitation, staff use and cleaning support; no process-water or steam system is part of the normal production route. This lower utility complexity is one reason a premix manufacturing plant in Brazil can be added to an existing feed site without replicating the infrastructure of a pellet mill. Utility simplicity does not remove the need for environmental control, however. Dust extraction, sealed transfer points, routine filter maintenance and cleanable surfaces are more important here because the plant handles many fine powders with high surface area and low bulk density.

Segregation Was the Harder Layout Problem

No additional land was purchased, so the two premix lines had to fit inside the existing operating envelope. The design priority was to keep concentrated powders and finished premix away from unnecessary contact with bulk-feed dust while still using the existing warehouse, electrical and dispatch infrastructure.

The retrofit focused on three layout changes:

• Re-route material flow so premix ingredients move from receiving and weighing toward mixing and packing without crossing conventional feed traffic
• Create a more controlled premix zone separated from the compound-feed process and its higher dust load
• Enclose key transfer points and connect them to local dust collection to reduce carryover and housekeeping load

Existing roof height also limited one planned conveyor route, so the transfer path was adjusted during installation. That is typical of retrofit engineering: the final design has to respect columns, floor elevations, access aisles and real equipment clearances, not just the dimensions shown on a preliminary drawing.

US$650,000 Fixed Investment for the Completed Expansion

• Premix equipment package: approximately US$420,000 for two parallel lines, dust collection, mixers, bins, elevators, packing systems and controls
• Completed fixed investment: approximately US$650,000 including local electrical work, workshop modification, installation, commissioning, freight, inland handling and integration with the existing factory

The investment should be read as a retrofit cost, not the cost of building a complete 12–13 T/H feed factory from empty land. The customer already owned the main site, warehouses, utilities and bulk-feed operation. That distinction is central for buyers comparing an animal feed premix plant in Brazil with a greenfield feed-mill project.

Qingdao to Santos Then Inland to the Existing Mill

• Origin port: Qingdao Port, China
• Destination port: Santos Port, Brazil

Sea transit was planned at roughly 45 days. From Santos, the premix equipment moved inland in the sequence needed for installation inside the operating workshop, with mixers, bins, packing equipment and dust-control components coordinated around the retrofit schedule.

Commissioning Was About Uniformity Before Throughput

The first production runs exposed two issues that matter in premix more than peak tonnage:

• Mixing uniformity needed improvement because carriers and mineral powders were not dispersing at the same rate
• Liquid addition created localized moisture differences when spray pressure and timing were too aggressive

The correction focused on process settings rather than adding more equipment:

• Mixing time was extended and the dry loading sequence was adjusted to create a more stable carrier bed
• Liquid spray pressure was reduced and addition timing was moved to a more suitable point in the mixing cycle

The acceptance criteria then shifted to repeatability:

• Batch uniformity met the customer’s internal quality target and routine sampling plan
• Both lines reached stable repeat operation after the commissioning adjustments were completed

Brazil Makes Premix a Quality-Control Business

The project fits Brazil because the customer already serves large livestock segments where feed consistency, mineral balance and traceability matter. A premix plant is not simply a smaller feed mill; it works closer to the nutritional specification and therefore puts more pressure on weighing, cleaning, batch identification and ingredient control. That is especially relevant for a feed company already supplying conventional products: the premix expansion can deepen the product portfolio and customer relationship without forcing the company to build another full grain-processing and pelleting system. The commercial advantage only holds, though, if the new department can maintain repeatable quality and clear product separation.

• Poultry feed programs that use concentrated vitamin, mineral and amino-acid systems
• Beef and dairy cattle programs using mineral and specialty premix products
• Integrated farms and commercial feed companies that need repeatable low-inclusion dosing

For a Brazil premix feed mill, the commercial opportunity is linked to three operational realities:

• Customers are moving toward more precise formulation and documented batch consistency
• Feed companies can add higher-concentration nutrition products without duplicating a complete pelleting plant
• Brazil’s large poultry and cattle industries create multiple application routes for specialized premix products

Compared with conventional pellet production, premix manufacturing changes the cost structure:

• Thermal and pelleting utilities are lower, but dust control, weighing and QA become more important
• Product value depends on formulation accuracy and consistency rather than bulk tonnage alone
• Changeover, cleaning and traceability can directly affect usable production capacity

The Best Premix Retrofit Starts With the Existing Factory

This 12–13 T/H premix feed production line in Brazil shows how existing feed mill engineering can be extended without duplicating an entire feed factory. The project uses the customer’s established site, warehouses, labor and market access, then adds the equipment and segregation needed for precision powder products.

The investment works because it is selective: two dedicated premix lines were added where the existing process could not deliver the required dosing, mixing and contamination control.

For a similar premix expansion, the first engineering review should cover four things:

• Existing ingredient receiving, storage and dust-control conditions
• Required weighing tolerance, mixer batch size and formula changeover frequency
• Available height, floor area, conveyor routes and separation from other feed products

The next step is to match those site constraints with the annual premix plan rather than choosing equipment from a headline T/H number. Batch size, number of formulas per day, cleaning frequency, liquid-addition percentage, bag specification and the share of poultry versus cattle products can all change the practical capacity of the same mixer. Those details should be fixed before finalizing bin sizes, elevator capacity, mixer volume and the number of packing stations.

• Send the annual premix tonnage and product categories.
• List the carriers, minerals, vitamins, liquids and low-inclusion ingredients that will actually be used.
• Provide the existing workshop drawing, working hours, packing requirements and utility conditions before the final line configuration is fixed.

That information allows RICHI to determine whether the project needs one line, two parallel lines, additional segregation or a larger site modification before the equipment package is quoted.
