I. Process Introduction

Oil press process:Pre-press machine is continuous screw press machine which is suitable to the plant oil materials which has high oil content.The instruction of the cake is loose and easy to make the solvent permeate ,the oil content of cake and moisture used for solvent extraction.

II.Towline Extractor Advantages:
1) The material is divided into several independent units on the material bed, which can effectively prevent miscella at all levels from fleeing hither and thither on the material layer and ensure the concentration gradient between several sprays.
2) Immersion area appears in each lattice, which can help achieve better immersion effect.
3) The chain box is supported by track and can prolong the service life of screen deck by not touching it.
4) The towline extractor is driven by world leading double-shaft hydraulic motor, with balance force, reliable operation and less maintenance cost.
5) Specialty suitable for the extraction of high oil and high power materials, and better immersion effect can be expected for ordinary oil plants.

III. Hydration Degumming & Alkali Refining Deacidification Process

Neutralization: the crude oil is output by the oil feed pump from the oil tank, and next enters the crude oil heat exchanger to recover part of heat after metering and then is heated to the required temperature by the heater. After that, the oil is mixed with the metered phosphoric acid or citric acid from phosphate tank in the gas mixture (M401), and then enters the conditioning tank (R401) to make the non-hydratable phospholipids in oil change into the hydratable phospholipids. Add the alkali for neutralization, and the alkali quantity and alkali solution concentration depend on the quality of the crude oil. Through the heater, the neutralized oil is heated to the temperature (90℃) suitable for centrifugal separation to remove the phospholipids, FFA and other impurities in the crude oil. Then the oil goes to the washing process.
