Small fish feed plant in Indonesia

RICHI MACHINERY

Two products need two capacity definitions

The poultry branch presses conditioned mash through a ring die. The fish branch uses extrusion followed by drying, cooling and grading. A single preparation area can serve both, but it must have enough batch time and correctly routed holding capacity. Concurrent operation is possible only after checking those shared duties; adding the two outlet ratings does not prove a continuous combined factory rate.

Ingredients selected for each feed route

The poultry recipe brief includes corn, rice bran, soybean meal and copra meal, with palm kernel cake considered only where the formulator accepts its nutrient and fibre contribution. These materials differ in bulk density, grind behaviour and storage condition. Receiving checks and actual analyses guide their use; availability alone does not establish a suitable inclusion rate.

The fish-feed brief uses finely prepared corn, selected bran, soybean meal, qualified fish meal and controlled oil additions, with premixes and other small ingredients weighed separately. Oil applied before extrusion and oil applied after drying have different effects. Excess oil in the extrusion mix can limit expansion, so the formula and addition point must be agreed together.

Deliveries through an Indonesian supplier may include both domestic and imported ingredients. The purchase specification therefore follows the ingredient and lot, rather than assuming one origin or one nutrient value. Bran freshness, meal condition and fish-meal quality matter to both physical processing and formulation. Supplier changes should trigger a recipe and processing review before a new lot is released.

Preparation divides into poultry and fish finishing

The small scale fish feed plant uses a common preparation concept followed by distinct processing branches. Weighing, grinding and mixing are scheduled to deliver the correct mash to each destination. Fish-feed mash requires its own agreed particle specification; a poultry grinding setting should not be adopted automatically for extrusion.

Weighing → Cleaning → Recipe-specific grinding → Mixing → Route selection → Poultry conditioning and pelleting OR Fish extrusion and drying → Cooling → Grading → Packing

The route selector is an operating control, not simply a tee in the conveyor. Batch identity, holding-bin destination and cleaning procedures need to agree before mash is discharged. When recipes share equipment, carryover is considered during production sequencing, with residual material returned only to a compatible feed batch.

Feed form follows the animal and recipe

Poultry pellets, poultry crumbs and floating fish pellets are separate product briefs. Crumbling poultry feed does not make it a suitable juvenile fish diet. Likewise, changing an extrusion die does not by itself qualify a recipe for ornamental fish. Each additional product needs a nutritional specification, a practical processing trial and an agreed release standard.

Equipment duties without an invented model list

The poultry press and floating-feed extruder perform different jobs. The poultry feed pellet machine must be matched to the intended poultry pellet size and formula, while the floating fish feed extruder machine must be matched to the fish recipe, die and dried-product duty. The contracted equipment categories are described below without assigning an unconfirmed model or motor power.

For this combined package, the feed mill equipment must be checked as a connected system. A press rating alone cannot establish bagged output. Shared preparation, transfers, dryer evaporation, cooling and bag handling can each restrict production. The technical schedule should identify those interfaces before dimensions, electrical loads or operating shifts are committed.

Plan the shared equipment around a realistic schedule

At the upper poultry reference duty, two tonnes of poultry feed require preparation for that route during each hour of continuous operation. A further 500 kg/h fish branch increases the shared demand only if both operate together. Sequential production reduces the instantaneous shared load, but the poultry and fish quantities then compete for available production time.

A holding bin can allow the extruder to continue while the mixer changes recipe, provided the bin contains the correct fish mash. Its usable quantity sets the bridging time. For example, 250 kg of usable mash supports a 500 kg/h draw for 30 minutes. This is a scheduling illustration, not a confirmed installed bin size or proof of simultaneous rated output.

The table gives planning arithmetic for this small fish feed plant in Indonesia. It excludes changeovers, start-up material, cleaning and downtime. Fish bag counts use dried, cooled and accepted feed, not wet extrudate. These boundaries keep production planning connected to the material that can actually be packed.

Drying and cooling define the fish-feed release point

For the 500 kg/h branch, the specification needs to state whether the quoted rate refers to mash, wet extrudate or finished feed. The project brief names the branch capacity but does not supply a performance-test basis. The engineering example below uses 500 kg/h of finished fish feed at 10% moisture to show the dryer calculation; it is not a certified output record.

With 25% moisture at the dryer inlet, 500 kg/h of finished feed at 10% moisture contains 450 kg/h of dry solids. Keeping those solids constant requires 600 kg/h of wet extrudate and removal of 100 kg/h of water. The inlet moisture is an illustrative assumption. Actual dryer selection needs measured inlet condition, recipe, air conditions and the agreed product endpoint.

After drying, fish feed must cool sufficiently for packing without condensation. In a warm, humid location, the available intake air and the finished-feed condition should be assessed together. A fixed storage-life promise cannot be derived from the country name, a dryer setting or a cooler alone. Moisture, water activity where appropriate, package condition and storage practice inform release.

Define the purchase around products and available services

A useful enquiry for a compact feed plant states the poultry and fish quantities separately, along with the intended fish pellet sizes, main ingredients and daily production window. It also identifies available power, water, heat services and building access. These details determine whether shared preparation is practical or whether particular duties need dedicated equipment.

Before accepting a small scale feed mill production arrangement, confirm the recipe-specific grinding requirement, batch schedule, extrusion output basis and dryer duty. Specify how rejected sizes and start-up material will be collected and assessed. Packing should accept only identified, cooled product; a nominal machine rate is not a substitute for an agreed finished-feed test.

RICHI can develop a small fish feed plant in Indonesia around the buyer’s actual product mix. Send the poultry and floating-feed targets separately, together with the raw-material list and available services, so the proposal can connect equipment selection, process routing and a realistic operating schedule.
