Zhengzhou Qi'E Grain & Oil Machinery Co., Ltd

/en

Basing on the traditional soybean  oil refining equipment , Zhengzhou Qi'E Grain & Oil Machinery Co., Ltd has developed the latest combined packing layer plate deodorization soft tower and the physical and chemical mixed refining technology for crude oil of any quality. Moreover, a series of advanced technology and equipment are used, such as super wet deguming, bleaching earth automatic metering, negative pressure decoloring, high vacuum steam jet deodorization, deacidification, winterization dewaxing etc. With advanced technology, superior equipment, full-automatic control and excellent economic and technical parameters, our equipment can meet customers' different refining requirements at home and abroad.

 The main Parts of edible oil refinery plant

 Crude oil→ degumming → deacidify → bleaching → deodorization → Heat-transfer oil stove→ Steam generator→ Vacuum pump → Press filter→  Air compressor

1. Crude oil: crude oil is commonly used for processing into edible oil .For example: palm oil,Sunflower oil,sesame oil,cotton seed oil,peanut oil,rice bran oil,palm oil,coconut  oil,soybean oil,apeseed oil,mustard seed oil,etc.  

2. Degumming :Usded to neutrilizing ,and water washing,to rid off the acid .

3. deacidify  : Acid stripping is removing hair oil contained in the free fatty acid process, acid stripping methods of alkali refining, steam distillation, solvent extraction, etc. 

4. bleaching  :Used to rid off the color of the oil

5. Deodorization:Used to rid off the fetid smell/odour of oil by steam understand of high temperature.
6. Heat-transfer oil stove: supply each device production needing heat energy, temperature reach above 280°C. 

7. Steam generator: produce the needing steam for de-odoring and distillation.

8. Vacuum pump: supply needing vacuum for dehydrate, de-color, de-odor. Vacuum degree can reach above 755mm Hg.

9. Press filter: filter clay, filter out clear oil.

10. Air compressor: blow dry bleached clay, blow empty the leftover oil in the press filter.

 The main process of edible oil refinery plant :

(1)Pump soybean oil into refining tank and heat with conduction oil, and the temperature will reach about 70°C-80°C after one hour.Add acid or alkali to separate according to the acid value. After one hour's processing and 4-6hours deposit, then convey soap stock to storage tank.

(2)Pump refined oil into decoloring tank. When it is up to 90-110°C after one hour's heating, add clay into tank for 20min's processing. Then separate clay and oil with filter.

(3)Put decolorizing oil into deodorization tank with vacuum pump. Heat and process with steam for odor removal.After filtering, you will get final oil product.
