1-90TPD castor oil expeller machine

Company Information

Our company is a manufacturer of all kinds of oil production line equipment; Our company was established in 1989. We have a big plant and have rich experience in this field. We have exported to many countries like Egypt, Chile, Argentina, Ethiopia, Zambia, Nigeria, Russia and Turkey ect.

1. castor oil press workshop craft:

• It is necessary for hulling the sunflowerseeds before pressing, so it could reduce the wax content of final oil, whcih is bad for human.
• Normally the oil pressing plant is composed of seeds cleaning & crushing unit, steaming and drying units, pressing unit, conveyor, electrical cabinet box, etc. The oil pressing unit as the main stage, to make the vegetable seeds flake in a hardened cage to squeeze oil content out. It's complete set of oil pressing equipment, which is automatically operated to save more labor and cost.
• Including to the following machinery and parts:
  Electrical apparatus control, materials feeder, conveyer, screening machine, steaming & frying machine, huller machine, medium boilor etc.
• The by-products from the oil press are cake and soap residue. The cake could be used as animal food with our pelleting machinery, or source material for the other way of extraction. Soap residue is the source material for laundry soap with soap making machinery and washing detergent.

2. castor oil extraction process machine workshop craft:

• The second way to extract oil for using chemical solvent to dissolve oil content contained in cake or direct oil seeds, only for lower oil seeds, for example soybean.
• Then oil is separated from solvent by vaporizing solvent out. In configuring the solvent extraction plant, pre-pressing may be involved in which case seeds are lightly pressed, and which leaves about 14% to 18% oil in the pressed cake.
• Solvent extraction will further process these cakes and leave less than 1% oil in the final cake. This method results in higher yields, more oil; Lower power consumption, lower wear & tear / maintenance and high extract efficiency.
• Thus it could be used as complement equipment to extract the oil remained in cake, which yields are extra profits. Certainly if the capacity is less than 50 tons, or it is high rate of output oil, this process could be saved.

3. castor oil refining process workshop craft:

• The crude vegetable oil from above mentioned two ways of extracting, oil pressing and/or solvent extraction, will be pumped into oil refinery units to produce cooking oil at various grades.
• The main equipment of oil refinery is various kinds of vessels and tanks carrying on different tasks with additives.
• These tasks may include sedimentation/filtering, neutralization (removing free fatty acid), degumming, decolorization (bleaching), deodorization, especially the dewax process is necessary, more wax would destroy the quality of sunflower oil.
• Different combination of steps and the treating degree of each step result in different grade cooking oil and salad oil.
