Equipment Needed For Soya Oil-Making Business

Seed Cleaning and Handling Equipment

The first crucial stage in soybean oil manufacturing is washing and processing the raw seeds.

Buy sturdy destoning machines, gravity separators, seed washers, and elevator buckets to efficiently remove mud, metals, sand, stones, immature seeds, and other soybean lot contaminants.

Specialized seed washing equipment maintains purity before extraction and reduces oil expeller wear.

Cracking, boiling, and flaking clean soybean seeds before oil extraction is essential. Bucket elevators, inclined belt conveyors, distributors, and hoppers are crucial to seed handling.

They carry soybean seeds vertically and horizontally between the cleaning unit and the cooking kettle. Based on manufacturing capacity, choose rugged screw, belt, and pneumatic conveyor systems with low downtime.

Seed Preparation Equipment

Preparing cracked and cleaned soybeans for the oil expeller is crucial. Essential steps include dehulling, frying, conditioning, and flaking. Strong, low-maintenance seed processing equipment boosts oil output and efficiency.

To dehull soybeans, buy modern machinery called hull separators. Then, a steam-jacketed kettle precisely cooks the dehulled cotyledons. Here, soybeans are cooked to maximize moisture and oil release. Adjustable steam control valves make heavy-duty kettles easier to customize.

After cooking, a Seed Crushing Plant, equipped with a roller flaking machine, crushed the soybean into homogeneous flakes with maximum oil cell exposure. Food-grade stainless steel flaking machines are easy to use and avoid contamination. Integration of robust cooling screw presses may help save energy in oil extraction.

Oil Extraction Equipment

Soybean oil extraction requires robust expellers, filters, and pumps. Consider processing capacity, energy demands, maintenance, and after-sales assistance when selecting a palm kernel oil expeller.

Screw-type oil presses work well for medium-sized applications. Hydraulic or spark ignition expellers configured for soybean's ideal 20% oil content may assist bigger operations.

Large mills extracting over 2000 tons per year may use commercially established solvent extraction plants employing food-grade hexane. However, this capital-intensive method requires experienced workers and strict environmental regulations. Good oil-collecting tanks, pumps, and filters help discharge.

Filtration and Refining Equipment

Pre-packaging crude soybean oil requires filtering and refining to remove gums, waxes, and color compounds. Progressively purify the oil using horizontal leaf, bag, and activated clay tower filters.

An edible oil refinery plant, equipped with modern auxiliary equipment, is used to optimize output purity by combining, deodorization, winterization, and bleaching. Based on output size and quality criteria, strategically buy neutralization, steam distillation, vacuum pumps, filters, centrifuges, and dosing equipment.

Storage Tanks and Filling Equipment

Finally, store refined soybean oil in food-grade stainless steel containers to avoid contamination and maintain quality until packing. Buy worldwide bulk storage tank systems with customizable capacity and automatic temperature adjustment. Storage and transport are more accessible with non-corrosive plastic barrels or jerry cans.

Automatic volumetric dosers and piston fillers maximize filling efficiency and minimize bottling waste. Optional capping mechanisms provide leak-proof packing for a longer shelf life. Integrating automated labeling equipment lets you brand and label your soybean oil-packed versions for B2B or retail.

Process For Soybean Oil Production

The soybean plant, Glycine max, is the source of soybean oil, which comprises between 18% and 20% oil by weight. The nutritional value, adaptability in cooking, and low price make it one of the most popular cooking oils in the world.

The primary processes for refining raw soybeans into this transparent, amber-colored oil are:

  • Cleaning : Cleaning the incoming soybeans eliminates contaminants such as dust, grime, stones, etc. The oil output and quality are both improved by this process.
  • Cracking & Dehulling : Cracking apart soybeans and removing their outer hulls reveals their oil-rich cotyledons.
  • Flaking : Rolling cotyledons into flakes enhances oil extraction by increasing the surface area.
  • Conditioning : Cooking the flakes at a certain temperature facilitates oil extraction while protecting the enzymes.
  • Pressing : Pressing the flakes of soybeans yields crude oil. To get greater yields, modern big plants use hexane-based solvent extraction.
  • Refining : To get refined, stable, and odorless soybean oil fit for consumption, crude oil goes through procedures such degumming, neutralization, bleaching, and deodorization.
  • Packaging : Shipped in food-safe containers, refined soybean oil is now ready for purchase.

Estimated Costs

A soybean oil factory startup in Nigeria necessitates a substantial financial outlay to secure prime industrial site, design and build a suitable plant, acquire necessary oil extraction and refining equipment, and fund early raw material and operational costs.
