Technological process details of  cotton seed oil refining machinery:        

1. Acid reaction 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

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). Oil soapstock of the separated (or foot) feet into the oil tank, and then to the salting out with soap pump tank isolated part of the oil.

3. Washing process

Neutral oil from separator, still contains about 500 ppm soap, in order to reduce the residual content of soap, oil is joined by about 10% of hot water, washed in the washing mixer, hot water will absorb oil soap and other impurities, then in the water separator are separated.

4.Vacuum drying section

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.

5.Bleaching 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. The carclazyte conveyor system power is the wind and the bleaching earth was conveyed to the carclazyte temporary storage tank in the upper part of the bleaching tower to supply the ratio mixer.

6. Filteration

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. There are two bleaching filters in this system, one of the bleaching filter is always in the state of filtering, another is in the state of emptying and cleaning state.

7.Deodorization 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.

When deodorized, odor material in oil will be removed under the condition of high temperature and high vacuum dryer,distilled fatty acid gas is discharged from the top of tower and it is collected by fatty acid catcher, thus, the environmental pollution will be reduced.

This equipment is made of stainless steel and adopts pad technology. It has high rate of mass transfer. So it reduces the retention time of oil retained in the vessel and guarantees the oil quality and its nutrition value.

The bleaching tower has following features:

1.Bleaching system at vacuum state can avoid oxidation;

2.Logical frame of bleaching tank makes the oil contact with clay evenly;

3.Equip with efficiency and effectively earth dosesing system that canbe running automatically;

4.Filter equipment running steadily, have less trouble and residual oil in meal is less.
