Oilseeds Puffing Machine

Oilseeds Puffing Machine


An oilseed puffing machine is for preprocessing high oil-content materials like rapeseeds, corn germ, or various pre-pressed oil cakes before sending them into an oil solvent extraction workshop. The puffing machine is suitable for soybean, rape seeds, cotton seeds, rice bran, etc. The puffing process of oil materials can improve oil yield, reduce energy consumption, and save investment in oil production equipment.


  • Increasing oil yield can increase production efficiency by 30-50%.
  • Shorten the extraction time and increase the leaching rate.
  • Reduce oil residue in oil meal.

Working Principle of Oilseed Puffing Machine

Oil materials are fed into the inlet of the puffing machine through the magnetic chute by the spiral quantitative feeder. The steam is added to the extruder cylinder through the direct steam throttle valve. The main spiral shaft, consisting of broken tooth screws, rotates in the cylinder to mix, press, heat, shear, and rub oil material. Cells of oil material are completely destroyed, and the oil in cells is fully exposed. Then the oil material is extruded from the mold hole on the template at high temperature and high pressure. When they are extruded out, the pressure suddenly decreases as well as the moisture evaporates rapidly, which causes the puffing of oil material.

Functions of Oilseed Bulking Machine

  1. Improve the productivity of oil solvent extractor
  2. Increase rate and shorten oil leaching time.
  3. Puffed materials absorb less solvent, so it is easy to dissolve.
  4. Increase the concentration of mixed oil, so decrease the load of evaporation of mixed oil.
  5. Enzymes in oil materials are passivated after puffing, so the quality of leached oil is improved.
  6. The processing capacity of the flaking machine is improved.
  7. Reduce energy consumption in the oil solvent extraction processing workshop.
