Feed Plant Integrated Processing System in Peru

RICHI MACHINERY

A Few Words Before the Drawings Started

The client first reached out in March 2025. At that point, there was no finalized layout—just a basic idea:

“We need something around 20–30 tons per hour, but we don’t want a complicated system that breaks every week.”

By June 2025, after several rounds of raw material analysis and layout revisions, the contract was signed. Equipment manufacturing started in July, and shipment from Qingdao Port to Callao Port (Peru) was arranged in October. Installation followed toward the end of the year.

Who Was Behind This Project?

This wasn’t a large multinational. The client was a regional agricultural investor group operating in northern Peru, already involved in grain trading and poultry farming.

Why build a plant like this?

• Increasing local demand for compound livestock feed
• Rising cost of importing finished feed
• Availability of corn and soybean meal supply chains
• Desire to control feed quality for their own farms

They weren’t looking for a “fancy factory.” They wanted something reliable, expandable, and not overly sensitive to operator skill level.

Site and General Layout

The animal feed processing plant sits on approximately 4,760 m² of land. The layout wasn’t random—it follows material flow logic more than architectural symmetry.

Main Sections:

• Raw Material Workshop
• Main Production Building (5 floors + 1 underground level)
• Finished Product Warehouse
• Auxiliary Facilities
• Boiler House
• Office & Lab Building

One thing that came up early:
The site had a natural elevation difference. Instead of leveling everything (expensive), the design used multi-level platforms to assist gravity flow inside the pelletizing line.

Product Plan

In this Feed Plant Integrated Processing System in Peru, before diving into machinery, the product mix defines everything.

The two animal feed production lines share some infrastructure but operate with different process priorities—especially in grinding and conditioning.

Raw Materials

In Peru, supply is relatively stable, but moisture and impurity levels fluctuate more than expected.

A small note from commissioning phase:
The first batches had inconsistent moisture due to corn variability. Adjustments were made in conditioning time rather than grinding size—this stabilized pellet quality quickly.

Complete Production Process

Below is the full process as implemented on-site. This is not simplified—this is how it actually runs.

① Raw Material Handling

The production materials are divided into:

• Granular materials: corn, wheat
• Powder materials: soybean meal, bran
• Micro-additives: vitamins, minerals

Granular and bulk materials are stored in vertical silos, while bagged materials are stored in the raw material warehouse.

This separation is important—it affects batching accuracy later.

② Cleaning and Magnetic Separation

Before entering the pelletizing line:

• Materials pass through drum screens to remove impurities such as stones, plastics, and debris
• Then pass through magnetic separators to remove metal particles

This step protects equipment and ensures feed safety.

Powder materials that do not require grinding are directly sent to batching bins.

③ Feeding System

• Ruminant line: 1 feeding inlet
• Livestock line: 2 feeding inlets

Materials are transferred via bucket elevators into either grinding bins or batching bins.

④ Grinding Process (Hammer Milling Stage)

Grinding is critical in this Feed Plant Integrated Processing System in Peru.

Configuration:

• 1 hammer mill for ruminant feed
• 2 hammer mills for livestock feed

Granular materials are fed into the grinding chamber via:

• Pneumatic gate control
• Impeller feeder for uniform feeding

Particle size is controlled by screen selection. A screen break detection point was reserved to prevent quality issues.

After grinding, materials are lifted and distributed into batching bins.

⑤ Batching and Mixing System

Ruminant line:

• 1 batching system
• 21 batching bins (including reserved bins for grass powder)
• 2 weighing scales

Livestock line:

• 1 batching system
• 28 batching bins
• multi-scale configuration (large, medium, small)

The batching process is fully automated:

• Formulas are entered into the control system
• Materials are weighed and discharged automatically
• Oil addition is controlled digitally

After batching, materials enter the mixer, then are conveyed to pelleting bins or finished bins.

⑥ Pelleting and Cooling

This is the core of the animal feed pellet plant.

• Materials are conditioned with saturated steam
• Steam is supplied by 2×2t/h natural gas boilers

Pellet mills:

• 3 feed mill pellet machines in total
• Different die sizes used depending on product

After pelleting:

• Pellets enter counterflow coolers
• Temperature is reduced to near ambient
• Moisture is stabilized

If required:

• Pellets are crushed or screened to achieve target size

⑦ Packaging System

• 3 automatic bagging machines
• Capacity:
  • 600 bags/hour (pellets)
  • 500 bags/hour (powder)

Investment Overview

• Total Investment: ~$1.8 million
• Feed Pellet Production Line Equipment: ~$1.2 million

The investment was optimized by:

• Shared conveying systems
• Practical automation level
• Efficient vertical layout

Real Commissioning Notes

Some things that don’t show in drawings:

• First few batches were either too wet or too dry
• Steam adjustment fixed most issues
• Operators needed more time on batching system than on machines
• Dust control worked well, but cleaning routines still matter

Market Perspective in Peru

Feed demand is growing steadily, especially in:

• Poultry sector
• Dairy farming
• Regional livestock production

Local feed production still has gaps in quality consistency.
A well-designed complete feed mill plant like this can operate both for internal supply and commercial sales.

Final Observation from This Project

This 25t/h Feed Plant Integrated Processing System in Peru works not because it is complex—but because it is balanced.

• Raw materials match process design
• Equipment matches operator capability
• Layout matches actual terrain

That’s usually where projects either succeed or fail.

If a similar feed mill factory is being considered, the first thing worth checking isn’t equipment—it’s raw material stability and product plan. The rest follows from there.
