Product Description


Soybean is a very common raw material for oil extraction. Its oil content is in the range of 15.6%-22.5% and contains 35%-45% of protein, It makes soybean a high-quality high-protein and high cost performance oil material.




In the programme of Hongde, Soybean oil extracting mainly includes three sections:


  • Soybean pre-treatment and pre-pressing
  • Soybean oil extraction
  • Soybean oil refining


Realated craft flow and equipments is as following:


1. Material Pre-treatment


In this section, the impurities in the soybean material will be removed and the soybean hulls will be separated. The bean embryo will be broken into small pieces and then processed into a puffed state. The purpose for this arrangement is to create a good production enviroment and minimize the total fat loss, increase oil yield and output and improve the quality of oil and cake & meal.







2. Oil Extraction


After sealed screw conveyor put the puffed soybean into exactor, the oil in extruded soybean will be dissolved by solvent, finally get crude oil. Compared with the pressing method, the residual rate of leaching is low (<1%) and offer a better quality meal. At the same time, this solution has the following features:

  1. Adopting negative pressure evaporation can ensure excellent oil quality;
  2. Extraction system is highly adaptable, and can adapt to different raw material ;
  3. All equipments are provided with exhaust gas absorption systems with excellent absorption effect;
  4. Full energy-saving design utilizes heat energy for many times and saves steam consumption.







3. Oil Refinery

Crude oil contains a large number of other ingredients that require further refining. In this section, continuous alkali refining shortens contact tome between oil and lye,which reduces oil saponification state,lowers refining consumption,and improves efficiency;negative pressure state avoids oxygen in the air from contacting with hot oil,thereby ensuring oil product quality ,inhibiting with hot oil,there by ensuring oil product quality,inhibiting acid value to rise again,and lowering peroxide value; physical refining section adopts new type continuous deacidiffication and deodorization craft, the actual production proves its most obvious advantages as following: strong deacidiffication ability ,excellent hot bleaching effect,high refining rate ,good oil quality etc.

Product Description

Introduction for black oil processing oil filter machine

Sunflower oil production process have two kind of processing method: pressing and leaching(extraction). Pressing method is by physical pressure and get oil directly from the oil seeds. The whole process does not involve any chemical additives, to ensure product safety, health, pollution-free. 


Hongde black oil processing oil filter machine  includes almost 4 parts,sunflower

seed prepress,sunflower cake extraction,crude sunflower oil refining,and finished

sunflower oil filling.


Process  for black oil processing oil filter machine

1.sunflower  seeds—cleaning—shelling—shell &nut separating—condition—flaking—cooking —prepress—filter—pre pressed  sunflower oil—oil refining—finished oil filling

2.Pre pressed cake—extraction—miscella steaming & stripping—extracted sunflower oil—degumming—de acidification—decolorizing—deodorizing—de waxing—finished sunflower oil filling
