250 KG Feed Mixer Machine with Compact Structure Design in the Philippines

The Farm Was Growing, but It Was Not an Industrial Feed Mill

The customer operates a semi-commercial swine farm in Cavite. Its herd is large enough that shovel mixing was no longer practical, but still too small to justify a multi-tonne automated feed plant.

This distinction is important in the Philippines. Under the Philippine Statistics Authority’s current farm definitions, swine operations with 11–50 sows are classified as semi-commercial, while farms with 51 or more sows fall into the commercial category. A compact 250 kg batch mixer therefore fits much more naturally into a farm in the semi-commercial range than into a 120-sow operation pretending to be a “small farm.”

The customer had expanded gradually rather than building all facilities at once. Feed storage, pig housing and equipment had been added around an existing layout, leaving no suitable area for a long horizontal mixer with complicated pneumatic discharge equipment.

Why the Old Manual Mixing Method Had Reached Its Limit

When the herd was smaller, workers prepared feed by weighing ingredients and blending them manually on a concrete mixing area.

That approach became increasingly difficult as daily feed volume grew.

The problem was not simply labour. Small quantities of vitamin-mineral premix, salt, calcium sources and other micro-ingredients were much harder to distribute uniformly through several hundred kilograms of maize, soybean meal and rice bran by shovel.

Visible ingredients could appear mixed while nutrient distribution inside the batch was still inconsistent.

The owner therefore wanted mechanical mixing before spending money on additional pelletizing or automated feeding equipment.

Why the SLHY0.5A Matched the Existing Feed Room

The SLHY0.5A Ribbon Mixer Machine was selected because its batch scale was appropriate for on-farm production and because the installation could remain comparatively simple.

The 250 kg batch size allows the farm to produce feed in several manageable batches rather than storing a large volume of finished feed for many days.

That matters in a warm, humid environment. Ingredients such as rice bran and mixed feed containing added fat can deteriorate more quickly when stored poorly, so producing smaller quantities more frequently can be preferable to mixing one very large batch and leaving it in storage.

Compact Design Means More Than a Small Machine Body

The customer initially focused only on whether the mixer would physically fit into the available corner.

RICHI also reviewed the working area around it.

Operators still need room to weigh ingredients, load the mixer, open the discharge, collect finished feed, inspect bearings and transmission components, and clean residual material from the mixing chamber.

A machine that technically fits between two walls but leaves no maintenance access is not a practical compact installation.

The final position therefore preserved service clearance while keeping the mixer close to the ingredient weighing point and finished-feed collection area.

No Compressed-Air System Was Added

The farm did not already have a compressed-air network.

Adding a compressor purely to operate the mixer discharge would have increased cost, electrical demand and maintenance for little benefit at this production scale.

The customer therefore selected a manual discharge arrangement.

For an operator making several 250 kg batches rather than dozens of tonnes per shift, the simpler mechanism was considered more appropriate than adding pneumatic automation for its own sake.

The Electrical Supply Was Confirmed before the Order

The 4 kW mixer motor was not automatically specified as a 220 V single-phase motor.

At this power level, commercial three-phase supply is the more practical arrangement where available, particularly for repeated daily starts and continuous agricultural operation.

The Cavite farm had access to suitable 60 Hz three-phase power at the feed room, so the motor and electrical controls were configured to match the site supply.

This check was completed before manufacturing. Motor power, voltage, frequency, starter arrangement and cable requirements were treated as installation parameters rather than assumptions based only on the country.

The Farm Uses Ingredients That Make Sense in a Philippine Swine Ration

The core formulation is based on ingredients commonly available through Philippine feed suppliers.

Ground maize provides much of the energy. Soybean meal is used as a major protein source, while rice bran or other suitable milling by-products can be incorporated according to nutrient specification and price.

Depending on the animal stage and the nutritionist’s formulation, small quantities of oil, amino acids, calcium and phosphorus sources, salt, vitamin-mineral premix and other approved additives are included.

Fishmeal may be used in selected piglet or higher-specification formulations, but the farm does not put 10% fishmeal into every grower-finisher batch simply because fishmeal is available in the Philippines.

The formula is adjusted according to pig stage rather than kept as one permanent recipe.

Why the Original 5% Premix and 5% Limestone-Salt Concept Was Rejected

Micro-ingredients require precision precisely because their inclusion rates are relatively small.

A vitamin-mineral premix is normally used according to the supplier’s formulation specification, not automatically at 5% of the complete feed.

The same applies to limestone, salt, phosphate sources and amino acids. Their inclusion must correspond to actual nutritional requirements.

The mixer therefore solves distribution, but it does not determine the formulation.

The customer continues to use a livestock nutritionist or an established feed formulation to set ingredient percentages.

Ingredient Weighing Became More Important after Mechanical Mixing

Installing a better mixer exposed another weakness in the old process.

Previously, workers occasionally estimated minor ingredient quantities using scoops or partially filled bags.

Once the SLHY0.5A was installed, the farm introduced more disciplined batch weighing.

Major ingredients are weighed before loading, while low-inclusion ingredients are measured separately and pre-blended where necessary before entering the main batch.

This prevents a technically good mixer from being used to mix an incorrectly weighed formulation.

Loading Sequence Was Adjusted for Micro-Ingredient Distribution

The farm does not simply dump every ingredient into the mixer in whatever order workers happen to carry the bags.

A portion of the major ground ingredient is loaded first, followed by protein ingredients and fibrous materials. Pre-weighed micro-ingredients are introduced in a way that gives them enough bulk material to disperse through rather than remaining concentrated in one small area of the mixer.

Where very low inclusion rates are involved, the micro-ingredients are first diluted with a portion of ground maize or another carrier.

This is particularly useful in a 250 kg batch because a few hundred grams of additive represent a very small fraction of the total mass.

Mixing Time Was Established by Batch Testing

The farm did not permanently set the mixer to five minutes because five minutes sounds convenient.

During commissioning, several batches were evaluated to determine when adequate uniformity had been achieved.

Running a ribbon mixer longer than necessary wastes electricity and reduces daily batch capacity. Stopping too early creates poor distribution.

The practical operating time was therefore established from the actual formulation, filling level and mixer performance.

The same procedure can be repeated if the farm later changes significantly to a formulation with more fibrous ingredients or added liquid.

A 250 kg Batch Does Not Last a Growing Pig Farm for Three Days

The mixer size was selected around batch frequency, not the assumption that 500 kg of feed could supply a semi-commercial breeding and grow-finish operation for several days.

Sows, boars, replacement animals, nursery pigs and grower-finishers collectively consume a substantial amount of feed.

The customer therefore runs multiple 250 kg batches according to the number and production stage of pigs present.

This makes the machine appropriate as a daily on-farm mixer rather than an occasional appliance used once every few days.

Different Pig Groups Are Mixed Separately

The customer prepares different diets for breeding stock and growing pigs.

A gestating sow does not have the same nutritional requirement as a lactating sow, newly weaned piglet or finishing pig.

Production is scheduled in batches so that one formulation is completed before the next begins.

Where necessary, a simple sequencing or flushing procedure is used before changing to a diet containing materially different additives.

This is more realistic than using one grower-finisher formula for every pig on the farm.

Manual Discharge Still Needed Good Workflow

The manual bottom discharge was selected for simplicity, but operators initially positioned collection containers too far from the outlet.

The working arrangement was changed so mixed feed could discharge into a mobile bin or collection container immediately below the mixer.

This reduced spillage and avoided carrying buckets back and forth across the ingredient area.

The change did not involve any new machinery, but it made the compact installation noticeably easier to operate.

Cleaning Is Especially Important in a Humid Feed Room

Cavite’s climate means residual feed should not be allowed to accumulate inside equipment or around the floor.

Fine feed mixed with humidity can cake on surfaces and attract insects or rodents.

The operator therefore removes visible residual material after production and periodically inspects areas that are not reached by normal discharge.

The mixer is kept dry rather than washed casually with large quantities of water after every batch, which could introduce corrosion and moisture into subsequent feed.

The Farm Did Not Use Tight-Lidded Buckets as Its Main Feed Storage System

At this scale, storing hundreds of kilograms of finished feed in domestic plastic buckets would be inefficient.

The customer instead uses covered feed bins or suitable bags for short-term storage and daily movement to the pig houses.

Production is scheduled so finished feed does not remain in the feed room unnecessarily long.

This reduces moisture uptake, pest exposure and excessive handling.

What Changed First Was Feed Consistency, Not Pig Growth Claims

The customer noticed that batches became more visually uniform and that fine ingredients were no longer concentrated in obvious patches.

Workers also spent substantially less time turning feed manually on the floor.

The farm did not attribute a precise improvement in growth rate, feed conversion or days to market solely to the mixer.

Pig performance also depends on genetics, health status, environment, feed formulation, ingredient quality and management.

The measurable process improvement was much simpler: ingredients could now be blended mechanically in repeatable batches.

The Philippine Farm Structure Supports This Type of Equipment

The project scale is consistent with the structure of the Philippine swine industry.

Philippine Statistics Authority data show that a large share of the national swine population continues to be raised in smallhold farms, while semi-commercial and commercial farms form the rest of the sector. As of June 30, 2025, the country had about 9.01 million swine, with approximately 71.6% in smallhold farms. 

PSA classifies operations with 1–10 sows as smallhold, 11–50 sows as semi-commercial and 51 or more sows as commercial.

This creates a genuine market between hand mixing and industrial feed mills: farms large enough to benefit from mechanized feed preparation but too small to justify multi-tonne mixers.

Why Cavite Was a Practical Location

Cavite gives the farm relatively convenient access to the Greater Manila market and commercial feed ingredients while still supporting intensive livestock operations outside the most densely developed urban areas.

The project did not depend on locally grown maize, soybean meal and fishmeal all coming from the immediate farm area.

Ingredients can be purchased through commercial feed-material suppliers and stored on site in quantities appropriate to the farm’s production schedule.

This is a more realistic sourcing model for a compact Cavite pig operation.

Shipping from Qingdao to Luzon

The SLHY0.5A was exported from Qingdao Port in China to the Manila-area port system and then delivered to Cavite by road.

RICHI provided machine dimensions, electrical requirements, installation information and recommended maintenance clearance before shipment.

That allowed the customer to confirm the equipment location, power connection and material-handling space before the mixer arrived.

No fixed sea-transit or customs-clearance time was promised because actual shipping schedules depend on the selected vessel, service route and port conditions.

The Customer’s Most Useful Lesson Was About Space Planning

“We originally measured only the empty floor area and thought that was enough. After installation we realized we also needed space to weigh bags, load ingredients, open the discharge and clean around the mixer. The machine is compact, but the working area around it matters just as much.”

This influenced the farm’s future equipment planning.

Instead of filling every remaining square metre with machinery, the owner now reserves access for feed movement and maintenance before approving additional equipment.

The Next Expansion Is Not Automatically a Bigger Mixer

If pig numbers increase, the farm will first compare daily feed demand with the number of SLHY0.5A batches required.

When batch frequency becomes inefficient, moving to a larger mixer may be justified.

However, the customer will also need to check ingredient weighing, grinding capacity, feed storage and internal transport.

Installing a 500 kg or larger mixer would provide little benefit if the hammer mill and weighing system could not prepare ingredients fast enough to keep it supplied.

Feed Mixer Machine with Compact Structure Design in the Philippines

This feed mixer machine with compact structure design in the Philippines project demonstrates where a small horizontal ribbon mixer makes practical sense: not in a large commercial feed mill and not on a household farm mixing a few buckets of feed, but in a semi-commercial pig operation that has outgrown manual mixing while still working inside an existing, space-constrained farm building.

The customer uses one SLHY0.5A with a 4 kW main motor and approximately 250 kg batch capacity. Its manual discharge keeps the installation simple, while the horizontal ribbon system provides repeatable mechanical blending of maize, soybean meal, rice bran and properly dosed micro-ingredients for different swine diets.

The compact structure is only one part of the solution. Reliable results also depend on accurate weighing, correct loading sequence, validated mixing time, appropriate filling level, dry ingredient storage, electrical compatibility and enough clearance around the machine for operators to work safely.

For another Philippine customer evaluating a feed mixer machine with compact structure design, RICHI Machinery would first review daily feed requirement, livestock numbers, diet types, number of batches, ingredient bulk density, micro-ingredient inclusion, existing grinder, available floor area, ceiling height, discharge method, electrical voltage and frequency, and how finished feed will be moved from the mixer to the livestock houses.

That calculation determines whether a 250 kg mixer is genuinely compact and efficient for the farm or simply too small for its actual daily feed demand.
