10-1000TPD Low consumption crude cooking oil refineries

                      Crude cooking oil refineries                         

1.   crude cooking oil refinery machine : 

1) The main function of decoloring process is to remove oil pigment, residual soap grain and metal ions. 

2) Under negative pressure, the mechanical mixing method combined with steam mixing will improve the 

decoloring  effect. 

3) The degummed oil firstly enters into the heater to be heated to the appropriate temperature (110°C), and then

goes to the bleaching earth mixing tank. 
4) The bleaching earth is delivered from the low bleaching box to the temporary tank by wind. 
5) The bleaching earth is added by automatic metering and is interlockingly controlled with the oil. 
6) The oil mixed with the bleaching earth overflows into the continuous decolorizer, which is stirred by non-powered steam. 
7) The decolored oil enters into the two alternate leaf filters to be filtered. 
8) Then the filtered oil enters the decolored oil storage tank through the security filter. 
9) The decolored oil storage tank is designed as the vacuum tank with the nozzle inside, so as to prevent the 

decolored oil contacting with the air and influencing its peroxide value and color reversion.

2. crude cooking oil refinery :  

(1) Refining section: used to P-acid de-gumming, alkali refining de-acid and water rinsing.

(2) Decoloring section: used to remove off pigments, bleaching oils and grease dehydrate.

(3) Deodorizing section: to remove off the odor components in oil.

(4) Dewax: used to remove off the wax in the oil, in order to get the high quality oil.

(5) Heat-transfer oil stove: supply each device production needing heat energy, temperature reach above 280°C.

(6) Steam generator: produce the needing steam for de-odoring and distillation.

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

(8) Press filter: filter clay, filter out clear oil.

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

3.  crude oil refinery machine:            

Refining pot: 

    Also named Dephosphorization and deacidification tank, under 60-70°C, it occurs acid-base neutralization 

reaction with sodium hydroxide. After stirring by reduction box,it can decrease the acid value in oil and separate

 the impurity, phospholipid which will enter into soap stock. The oil can be refined further.

Bleaching pot (decoloring pot): 

    Also named bleaching and dewatering pot, it removes water from oil by vacuum. The bleaching earth is 

breathed into bleaching pot, after stirring,filtrated by filter and change the color of the oil.

Vertical blade filter machine:

    Equipped with vertical leaf filter to remove used bentonite from the oil, operating conveniently and continuously,

 low laboring tense, keeps environment well, keeps oil residence in deposable bleaching earth in low level.

Deodorization pot:

  It uses USU 304 stainless steel plate, under the vacuum condition of vacuum and high temperature (220-240°C), The deodorization system can remove fatty acid and other  rare delicacy high efficiently .make Meanwhile, the 

pot has the advantage of lowering steam consuming and avoid of the hydrolyzation of oil

Safety:

1) We use auto welding machine to make the reactor,which can quarrantee the quality of welding seam,avoid cracking and has a long life for about 8 years.
2) Professional heating treatment and x-ray detection chamber for welding seam .
3) Vacuum system to prevent oil gas be back to reactor causing accident.
4) With professional thermometer , professiona pressure gauge and safety valve.

Environment friendly:

1) Dedusting system to prevent gas and dust from coal burning
2) The exhaust gas will be recycled for heating reactor ,no gas pollution
3) Well sealing on every junction parts to prevent gas leak,no smelly

Longer service life :
Using Q345R special steel plate ,welding seam with auto welding an will get heating treatment and x-ray detection to extend the life of reactor to the most extend, and the life will 8 years.

Energy saving:
1) Well sealing for heating system ,no gas leak and saving fuel.
2) The exhaust gas will be recycled for reactor heating.
