China Huatai Crude Sunflower Oil Dewaxing Machine with Good Refining Effect

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 Huatai, Soybean oil extracting mainly includes three sections:

portant;font-size:14px;">Soybean pre-treatment and pre-pressingportant;font-size:14px;">Soybean oil extractionportant;font-size:14px;">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:

portant;font-size:14px;">Adopting negative pressure evaporation can ensure excellent oil quality;portant;font-size:14px;">Extraction system is highly adaptable, and can adapt to different raw material ;portant;font-size:14px;">All equipments are provided with exhaust gas absorption systems with excellent absorption effect;portant;font-size:14px;">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.

The common Sunflower Oil Refining Plant includes three sections:

(There are mainly three kind production craft: batch refining, semi-continuous refining and fullly continuous refining. Our engineers can design the plant according to your requests)

1. Crude sunflower oil degumming, water washing and drying process

2. Crude sunflower oil bleaching process

3. Crude sunflower oil dewaxing process

4. Crude sunflower oil deodorization process

The followings are details description of the refining processes:

---Technology Description of Crude Sunflower Oil Dewaxing Machine:

1). Degumming, Water Washing and Drying Section
The solid impurities in crude sunflower oil will be removed by bag filter, and measured accurately by mass flowmeter, and then enter the degumming workshop to remove the colloidal, the crude sunflower oil heated will be ex-changed the heated, it will be fully mixed with phosphoric acid, the mixture will react in the acid tank. After the reaction, the alkali liquid will be added in, the partial neutralization reaction will be done here, and then the colloidal, starch and other impurities contains in oil will be separated out.

All temperature in the whole degumming process is automatic control and adjustable, and all operations can completely achieve in control room.

2). Decoloring Section of Crude Sunflower Oil Dewaxing Machine

The decoloring section adopt 50 tons/day device. The degummed oil will be pre-heated by the deodorization refined oil, then it will be heated and enter pre-mixing tank. Meanwhile, the clay which is measured by metering device directly in clay tank, and then the measured clay will be added to the pre-mixing tank. After a fully mixing, the mixture of clay and oil will be sent into the decoloring tower, the color will be removed here.

The decolorization reaction in decoloring tower will last about 30-60 minutes. Then the mixture will be pumped out and filtered by Armagh filter, the waste clay will be separated from the oil. The residue clay particle will be firstly filtered by the precision filter and then go into the gassing evolution tank to remove the moisture and volatile matter. The whole decolorization process temperature is self-control and adjustable. The filtration system has achieved the feeding oil automatically, circulation, filtration, baked cakes, slag and other operations by manual implementation .

The decoloring section design trapping odor device, the odor in the steam will be purged by the circulating water, thus to eliminate odor pollution in decolorization.

Bleaching Pot

3). Dewaxing Section (Winterization process)
The deodorization oil gets into the crystallizing tank, the cooler will adjust the temperature to 50ºC, then in crystallizing tank the cooling water will cool the oil to 20ºC, after 72 hours crystallization, filter the oil to remove the wax.

4). Deodorization Section of Crude Sunflower Oil Dewaxing Machine

Gas substances from the dewaxing oil from the winterization section will enter the deodorization section to remove the free fatty acids and unpleasant gas. All of this will be removed under the high vacuum circumsatnces by the deodorization tower. Using the to remove these substances by steam under high vacuum conditions. The removed fatty acid will be collected by the fatty acid trap and pumped into the receiving tank, this later will be used as vice products.

In order to save energy, the decolored oil will firstly heat ex-changed with the deodorization oil by heat ex-changer, and then heated to the deodorization temperature of about 235-236ºC by high pressure steam.

The water ring vacuum pump was adopted in the deodorization section vacuum system, the extracted odor in deodorizing vacuum will be trapped by the circulating water, thus to eliminate the odor pollution in deodorizing section.
