Specifications of : 30T/D----800T/D Soybean oil machine
Soybean oil pretreatment workshop:
1) Weighing: Soybean is firstly stored in buffer tank which is for adjusting the soybean flow. By means of weighter the processed
Soybean is weighted and the imputing quantity is accumulated.
2) leaning and Impurities separating: By means of Vibrating Sieve the larger and smaller size impurities in Soybean are removed out.
3) Gravity De-stoner & Magnetic Separating: some impurities which are as almost same size as Soybean are still mixed in Soybean,
but as their gravity or nature properties are different, by means of Gravity De-stoner and Magnetic Separator ,
the heavy stone and ferric impurities are separated out from Soybean.
4) Crushing & De-hulling: In order to increase protein content in Soya Meal, the de-hulling process is very significant. De-hulling system is composed of Cracking by two Crushing Mill which breaks Soybean into small pieces, and twice separating by Aspirators which separates Soy Hull out from Soya Meal.
5) Flaking: Flaking Machine is adopted for flaking Soya Meat into thin Flake, during which Soybean cell tissue is destroyed.
6) Expanding: The Soya Flake is fed into Expander in which heat is produced with the functions of kneading, friction between the spiral shaft and inner wall of the Expander,
meanwhile eject in steam to increase Soya Flake temperature.
7) Drying & Cooling: Jetting out from the end of expander, the Soya Cake is very moist and hot , it should be dried at moisture content 9.5% or so, and cooled down to about 60°C by counter-current-wise down in Cooling Dryer, and then the dried Soya Cake is conveyed into Extraction workshop.
Soybean oil extraction workshop :
Towline Extractor Advantages
1,The material is divided into several independent units on the material bed, which can effectively prevent miscella at all levels from fleeing hither
and thither on the material layer and ensure the concentration gradient between several sprays.
2, Immersion area appears in each lattice, which can help achieve better immersion effect.
3, The chain box is supported by track and can prolong the service life of screen deck by not touching it.
4, The towline extractor is driven by world leading double-shaft hydraulic motor, with balance force, reliable operation and less maintenance cost.
5, Specialty suitable for the extraction of high oil and high power materials, and better immersion effect can be expected for ordinary oil plants.
Soybean oil refining workshop :
1) Hydrating & Degumming: The Crude Oil firstly is filtered by Filters for removing out mechanical impurities out from, and then has heat-exchange in Heat Exchanger with hot Refined Oil, next is heated by Heater to the appropriate temperature. After being mixed with hot water
by Mixer , it is pumped into Hydrating Reactor in which most phospholipids will be hydrated into flocculent Lecithin Gum.
2) Neutralizing & Degumming: Adding in appropriate Lye by Dosing Pump and mixing them by Mixer , the oil is pumped into Neutralizing Reactor
in the hydratable phospholipids as well as acid are saponified into Soapstock Gum.
3) Washing: There are residual soapstock still remains in degummed and neutralized oil. Adding Hot Water and mixing with oil by Mixer, the residual
soapstock will be solved completely into washing water.
4) Bleaching. The Degummed Oil firstly heat-exchange in Heat Exchanger with hot Refined Oil, next is heated by Heater up to 110°C. And then enters into oil-clay mixer in which it is mixed with Bleaching Clay. next the mixture of oil-clay enters into Bleaching Tower in which the most pigment in oil will be adsorbed by Bleaching Clay.
5) Deacidifying & Deodorizing: The Bleached Oil contains some odouring substance which mostly are free fatty acids. By means of Assorted De-acidifying & Deodorizing Tower, under high temperature and vacuum condition, these free fatty acids will be stripped out from oil. The odouring substances
are caught in Fatty Acid Scrubber and collected in Fatty Acid Tank .
