Animal feed processing line in Bhutan

RICHI MACHINERY

Use specified dry ingredients rather than unrestricted local residues

The dual-process feed plant in Bhutan uses grains, bran, qualified protein meals and small additions selected for each diet. Some ingredients can come through local cereal or milling channels; others need regional suppliers. The equipment scope does not require every ingredient to be produced domestically. Incoming form, moisture and quality determine the preparation route before the nutritional role is considered.

Shared preparation leads to two distinct product-forming branches

This commercial feed mill combines extrusion and ring-die pelleting. Grinding, batching and mixing must be checked against the recipe and the selected branch. Extruded fish or pet products generally require a different grind and moisture programme from ordinary compound livestock pellets. The shared preparation assets are scheduled accordingly, with clear destination control for each batch.

PLC controls support weighing and routing, while operators verify ingredient identity, small additions and product release. Automation does not replace nutritional formulation or eliminate weighing and transfer errors. The configured flow is organised around these duties:

Feed form and size are selected for a specific product

The aquatic and pet feed line in Bhutan forms products through extrusion, followed by matched moisture removal and finishing. The livestock and poultry feed line in Bhutan follows the separate press route. The sizes below are design selections for the product brief; smaller dies, different recipes and demanding density targets require their own working-rate review.

The animal feed production line can be reviewed for additional compatible diets, including selected small-ruminant or bird feeds. That review covers ingredient preparation, formulation, die selection and carryover control. Each additional grade needs a defined formulation and process trial. Shrimp microfeeds and high-oil trout feeds introduce additional requirements for fine preparation, water stability or oil uptake, which must be assessed separately from the reference output claims.

Floating or sinking behaviour is a product specification, not a result assigned by the fish species alone. Recipe, extrusion settings, moisture, expansion and coating influence density and water behaviour. Representative finished feed is tested before it is released under a density or stability description. The small extrusion route is not presented as producing every aquatic grade at one unchanged rate.

The branch machinery is matched to different finishing tasks

The animal feed manufacturing machine package combines preparation and product-forming assemblies. For the pellet branch, one SZLH320 with a 37 kW main motor serves the reference 3–4 T/H duty. The extrusion selection is one SPHS75×2 twin-screw machine with a 55 kW main drive, serving the 0.8–1 T/H reference finished-product programme. Main-drive ratings are not complete factory connected-load figures.

The equipment schedule keeps the route interfaces visible:

Shared equipment is a scheduling decision. Before two branches run together, the receiving, grinding, mixer cycle, transfer equipment and available services must support their combined demand. Otherwise the mixer supplies planned batches to one branch at a time. The branch nameplate figures are not added to claim 4–5 T/H of simultaneous finished output. This distinction helps the owner plan batch sizes, staffing and stock movements without confusing installed capacity with an achieved production schedule.

A moisture calculation includes the coating added after drying

For this animal feed processing line in Bhutan, dryer selection follows wet-feed condition and the finished-product target. The calculation below uses a reference extruded batch, including post-drying oil, so that added coating is not omitted from the mass balance. It assumes no external dry-matter loss; clean fines are internal circulation. The values are interface-sizing conditions, not site measurements or a mandatory recipe.

Pet recipes need separate nutritional and production identities

The dry pet food production line in Bhutan requires specific dog and cat formulations, despite sharing an extruder. Protein sources, starch system, fat addition and micronutrient provision follow the intended diet and life stage. Processing a kibble shape does not establish nutritional completeness. Qualified formulation, ingredient checks and appropriate product assessment remain part of releasing a feed under its intended description.

Coating duty also needs a product-specific review. A simple oil-spraying system has a different role from a vacuum-coating installation intended for greater internal oil uptake. The selected liquid amount, dried-product structure and application sequence influence the finished result. Oil addition cannot be increased without reviewing surface condition, handling, packaging and storage behaviour. The coating specification follows the approved product brief and its release checks.

Grade changes are controlled before another batch is released

The combined feed factory in Bhutan needs a clear changeover sequence across raw-material bins, mixers, transfers and finished-product positions. Operators identify the preceding product, check residual material and confirm the destination of the next batch. Small additions and liquid settings follow the issued formula. Where carryover matters, the production sequence and cleaning method are reviewed for the particular products instead of assuming that a shared line is suitable without qualification.

The contract milestone in May 2025 defines the agreed commercial scope. Commissioning procedures cover preparation, batch transfer, branch selection, extrusion or pressing, finishing and bag identification. Operator instruction connects the machine settings with feed condition and product release. Start-up checks follow the material through the selected branch, while batch records connect the resulting product with its recipe and operating settings.

For RICHI, the animal feed processing line in Bhutan centres on the interfaces between the branches. The owner needs a repeatable prepared batch for the selected forming process, sufficient drying or cooling for its discharge, and a finished grade that can be identified in storage and delivery. This is a more useful scope than treating the extrusion and pellet capacities as interchangeable descriptions of one machine.

A comparable small commercial feed plant in Bhutan starts with its intended products, ingredient forms, recipe range and required finished output. Existing power, heat supply, building access and storage arrangements complete the equipment brief. RICHI uses those details to review the shared preparation cycle and the separate branch duties, allowing the buyer to assess the production commitment before confirming a complete package.
