What are the Key Areas for Establishing a Soybean Oil Plant?

Soybean oil is an oil extracted from soybeans and is one of the most commonly used cooking oils. Soybean oil has higher nutritional value than other oils, so the market demand is high. Therefore, the establishment of a soybean oil extraction plant has a very promising market prospect.

Necessary Machinery of Soybean Oil Plant
The following list shows the amount of equipment required for normal production of soybean oil plants and the cost of them.

  1. Seed Cleaning (Machine): $5,500.00 - $6,500.00
  2. Crushing (Machine): $8,000.00 - $9,000.00
  3. Flaking (Machine): $800.00 - 35,000.00
  4. Steam Cooking (Machine): $14,000.00 - $16,000.00
  5. Oil Pressing (Machine): $10,000.00 - $250,000.00
  6. Oil Filter (Machine): $2,000.00 - $100,000.00
There are large soybean oil plants, and there is also a small one. But for starters, it's wise to start small then expand later. For a small one, you only need four machines. Soya bean Oil Seed Cracker, Soya bean Oil Expeller, Soya bean Handling System, and Oil Filter. For medium ones, we need six. A seed cleaning, crushing, flaking, steam cooking, oil pressing, and oil filter. For large plants, take the medium machines and make it larger. But for most large-scale soybean oil plants, there is a different way of extracting oil from soybeans. It is called solvent extraction. When extracting on a large scale, this process is efficient and can yield oil better than other processes. Its price is ranging from $289,000.00 - 1,890,000.00.


How to Make Soybean Oil?

Oil Seed Cleaning

The oilseed in the harvest, in the process of transportation and storage will be mixed with some impurities, so the oilseed import production workshop after the need for further clean-up, the impurity content dropped to within the scope of technical requirements, to ensure that the process effect of oil production and product quality.

Soybean Softening

The horizontal softening machine is adopted here to heat the soybean to 50-70℃. Therefore, the plasticity of soybean is increased through adjusting the moisture and temperature, creating good operation condition for flaking and cooking. The softening process can not only make the flake become thin, uniform and tough, but reduce the nonhydratable phospholipids content in crude oil, which is convenient for the dephosphorization and physical refining of salad oil.

Soybean Flaking

The purpose of the flaking is to destroy the cell structure of oilseed, increase the surface area of oilseed, shorten the distance of oil outflow, is conducive to the extraction of oil, but also help to improve the effect of steaming. The main equipment is the flaking rolling machine.

Solvent Extracting Process

The pretreated soybean flakes are sent to the soybean solvent extraction plant. The plant uses a kind of solvent (normal hexane) to absorb the oil from soybean, and then the machines separate the solvent from soybean crude oil. The solvent is used for recycling and soybean crude oil is refined by oil refinery plant.
