BATCH SYSTEM REFINERY

PROCESS EXPLANATION

Costic refining is a process of neutralizing row plant oil chemically. This process is done for changing into soap, the oil acid in oil consisting of mixing the oil with costic mineral water and removing the formatted deposit by santrafuj separating system.

This process is very suitable for most of edible oils and provide to produce first class edible oil after refining. For obtaining first-class oil, the row oil entered through the smelling unit must be decompositated from unpureness  substances. Costic naturalization and bleaching is a required process of production of pureted oil.

Rafination of oil consists of three steps:

1.      Stipulation by acid

2.      Naturalization

3.      Washing with water

1. Stipulating Row-oil with Acid: During this process phosphorus acid is added. Reaches to a definite heat and taken into recreation giving water to the tank.

2. Neutralization: The water filled is taken out from the bottom and costic is started to be added according to acid in oil. Mixing process is done, salty water is added and left for waiting. Soap-stock is taken away from the tank. Then, the water in the tank is taken after

that the tank is filled with normal water again and left for waiting. After then the water is taken away again. Continuously after taking the oil is heated and costic is added and mixing is done. Then the process is stopped and pure water is added is same amount and left

for waiting again. At that time, soap-stock is taken away from the bottom.

3.Washing With Water:  Naturaliste oil still contains soap remainder which must be minimized before more process is applied. An amount of pure water is added to oil and after that the process continues until the soap remainders separate from oil and the water is clear. Following oil is send to bleaching unit’s drying tank. In this tank, the moisture left is reduced by under vacuum.

BLEACHING UNIT

PROCESS EXPLANATION

The main purpose in bleaching by using absorption method is; by taking away the color in the product. On the other hand, bleaching, in refining system is useful for losing the soap remainders before deodorization’s last part. This system creates benefit for working

force and also the area using. This system also depends on using much less bleaching earth to obtain the same bleaching results.

The mixing process of oil is started after taking the water away from the tank which is also used for drying. After holding the vacuum, stream is atomizing when the heat reaches to a determined lower, the earth is atomized with vacuum. The stream is closed when the mixture of earth and oil reach the desired heat and then the process finishes. Oil and earth is separated from each other, sending the filters by the pump.

WINTERIZATION UNIT

PROCESS EXPLANATION

When some kind of oil is cooled up to room temperature, it is in turbid color. This is some for sunflower and corn oil. Even in lower temperatures, to remain clear, oil should be winterized.

WINTERIZATION OF VEGATABLE OIL

High fusion provides paraffin’s (waxes) to remove, sometimes high fusion also gets Stearns remove, and Winterization is completed in three steps.

First step: Oil is in winterizing tank.

Second step: Filter helping material is added and oil is cooled slowly.  Oil should be waited a lower temperature in a few hours to obtain a suitable cold testing before oil filtration.

Last step: Oil is hold sometime in oil mature and before filtering to mature after then oil is send to filters to filtrate.

DEODORIZATION UNIT

PROCESS EXPLANATION

One  of the most important part of the oil refining is the deodorization (removal of the odor) which gives the appropriate value to the oil. The most important fact which the consumer interests mainly about liquid oil is the odor and taste. The oil gains all these specialties in deodorizing agents. That’s why deodorizing agents are very important in oil sector. Every kind of oil has got an odor, that belongs to itself. And this odor is got rid of, by deodorizing agents

1.      Vacuum

2.      Heat

3.      Distillation Steam

4.      The thickness of oil layer

5.      Timing

1. VACUUM

To reduce the heat of evaporating, the atmosphere pressure should be reduced to the lowest level for the materials which give odor , to evaporate .After long studies about this subject, the reduce is done down to 2 mm Hg in absolute pressure.(2 torr)

2. TEMPERATURE

There are two main roles of temperature. On one hand, the pressure in evaporation, of undesired odor material is getting higher related to the reason of high temperature in surrounding; on the other hand it helps oil acids to be distilled easily, providing hydrocarbons with shorter chain structures by exploring oil acid chains to aldehits and ketons. That’s why the temperature is very important factor.

3. DESTILATION STEAM

It is very important to pay attention to the clear steam to be dry and degassed while deodorization process is going on. On one hand, while deodorization process, the steam atomized directly to the oil holds the mission of mixing, on the other hand it lowers the evaporation pressure as if it is a distillation specialty to provide easy evaporation. It helps oxidized oil acids to be broken into aldehids and katons in high temperatures.

4. THICKNESS OF OL LAYER

By capturing it under vacuum, it gets rid of atmospheric pressure. By this way, a pressure appears at the lowest part of the oil because of its own weight, as if it is remaining a thick level. This increase availability of evaporating pressures of molecules at the bottom level so these natures’ oils to be remaining in higher levels while removing of odor (deodorization) process. This is an undesired specialty.

5. TIMING

Because it is a distillation process; if preparation of 4 factors, mentioned above, is in optimum timing shapes most appropriate position by itself naturally. If those 4 factors cannot be manager successfully deodorization process should be left for timing process. But, as the time passes, the prime cost gets higher.
