Technical description:

  The process is for pretreatment for removing out the impurities from the vegetable oil materials. These impurities are generally referred to as organic and inorganic impurities. The organic impurities include the stem leaf, cord, chemical fibers, velveteen and their seeds. The inorganic impurities, however, sometimes mean soil, dinas and metal.The vegetable oil processing industry involves the extraction and processing of oils and fats from vegetable sources.

  The main Technical process 


                            Pressing/Pre-pressing technology                                 Crushing &  Extrusion technology


The new technology 

Recently In order to overcome the shortcoming of the poor quality protein of the cake and meal from the pre-pressing & solvent extraction process,we develop the new processing technology,these technology also could get the high quality crude oil.


             Extruding & Pressing Technology                               Cold Pressing technology                            


The extruding & Pressing Technology 

It adopts the extruder to replace the traditional steam cooker vessel,to heat the seeds in shortly time, to make the oil cell expanding, keep the protein not destroyed , to get the good quality cake for the animal food . 

The advantage with extruding-pressing method: 

1.The crude oil quality is higher. The phospholipids of crude oil (150 ppm) is lower than cooking-pressing method (500-700 ppm). Also the better original oil color. The final oil is not required to refining. The final oil is 100% green edible oil .

2.The final oil yield is higher, about 98%, the residue oil of cake could be controlled to 4-5%. 

The protein denaturation is less. The protein is destroyed small because of the shortly time heating (20s or so) in the extruder,so the protein is high quality for animal food or raw materials of human food .

3.The life of oil press is longer, also improve the capacity 50% more.

4.Energy consumption is less than cooking-pressing method. The extruder only requries the less steam than steam cooker . 

5.Save the investment and working cost . Not require to use the solvent extraction process with the less oil in cake.
