Soybeans have a relatively high oil yield. The press can process various oil-bearing crops such as rapeseed, cottonseed, soybeans, peanuts, flaxseed, palm oil, coconut shells, olives, castor beans, sesame seeds, sunflower seeds, rice bran, corn germ, walnuts, almonds, evening primrose, tea seeds, and pine nuts. The advantages of a soybean oil press include low energy consumption, a small footprint (only a few square meters), and the ability to connect to a computer controller for automated operation. Furthermore, soybean oil presses maintain the advantages of simple structure and long service life.

The soybean oil press incorporates an automatic temperature control system, allowing for adjustment of the temperature to suit different raw materials, simplifying the oil extraction process. The soybean oil press utilizes mechanical pressure to generate heat as the oil-bearing material is pushed by the screw shaft, causing the oil to separate from the material and flow out. This process is called extraction. The design principle of the soybean oil press is considered the best in the world, enabling automatic pressing and automatic residue discharge. Soybean oil pressing is classified by the number of pressing stages: single-stage, two-stage, and multi-stage pressing. Sizes range from small to medium to large.
Choosing the right equipment is crucial. When selecting equipment, consider:
1. The operating pressure of the equipment (higher pressure generally yields higher oil extraction rates).
2. The oil residue content of the equipment (lower residue content means higher oil yield).
3. The residual oil content of the pressed cake (lower residual oil content means higher oil production).
