soybean  oil refinery  plant refers to a series of refining processes that can remove phospholipids, FFA, pigment, off-flavor and other impurities in the oil. The process of removing these impurities after oil extraction section is called   soybean   oil refining plant . The crude oil obtained either from expellers or solvent extraction plant contains impurities, which must be removed to make the oil edible, more palatable and stable against rancidity upon storage.

With over 16 years experience of designing and installing complete crude oil refinery plant, we are now a leading company in edible or vegetable oil refinery field. We supply various edible or vegetable oil refining plant and technology with high quality and competitive price to ensure that best finished oil is achieved.

The specification of      palm oil refining process

Main Process of   palm oil refining process    :

There are two ways to move the acid in the soybean oil. One is chemical way, the other one is physical way. The chemical way is using NaOH to react with acid. This way is suitable for the capacity of 5-30T per day. The physical way is using steam and centrifugal to move the acid. This way is used for capacity from 30-2000T per day.

1. Acid reaction process of     palm oil refining process

Oil temperature can be adjusted by screw plate heat exchanger. When the temperature is heated to about 80℃, mixing about 85% food grade phosphoric acid into acid reaction tank for reacting. In the tank, most non-hydrated phospholipid transfer into hydrated phospholipid.

2. Neutralization process of    palm oil refining process

In the neutral section, degummed oil with appropriate temperature and the appropriate concentration of alkali liquor, into the neutralization centrifugal mixer mixing, in order to achieve the best effect of mixed, the mixture is then sent to neutralization tank for enough time, in this process, excessive alkali neutralization of free fatty acids and some phosphate form soapstock , after pumping oil soap mixture into heater oil heating to 85 ~ 90 ℃ in centrifuge separation oil - soap (or oil - glue).

3.Vacuum drying section of   palm oil refining process

The neutralization and washing oil separated from the washing separator still contains some residual water adverse to the oil stability, in order to get rid of these water, the oil is sent to the vacuum dryer to dry when the temperature is still at about 110-120°C, the dried oil is sent to the bleaching section directly by the oil bank.

4.Bleaching process of  palm oil refining process

The main purpose of this procedure is to remove the pigments and residual soup in the neutralization oil of the crude oil. The oil is sent to vacuum bleaching tower after heated to 105°C. When the oil is sent into the tower, it is mixed by the ratio mixer with carclazyte whose dosing was control by a program controller and the dosing unit is installed on the ratio mixer directly.

5. Filteration of  palm oil refining process

Miscella mixed by oil and clay from decolorization tower is pumped into bleaching tower, then enters fine filter, in which clay and fixed impurities is blocked. And the filtering substance (bleached oil) is transferred into storage tank of bleached oil.

6.Deodorization process of   palm oil refining process

Deodorization process aims to remove the FFA, low molecular compounds and others existing in bleached oil. The flow of bleached oil entering deodorization process is controlled by a flow controller, and the oil is heated to the deodorization temperature of 250-260℃ through a series of heat exchanger.
