Pretreatment workshop mainly through cleaning,flaking and steam cooking, etc.Reform the shape of oil,the greatest degree to
improve the oil quality. In order to quickly and efficiently make oil by pressing or solvent extracting. Ensure that subsequent
sections smoothly.
1.Magnetic box and cleaning screen :To move the impurities in the raw materials.This can help to protect the following machines.
2.Crushing:Crushing is necessary for soybean oil making, because the volume of soybean is a little big. In order to improve the oil
yield rate and protect the following machines, we need to crush big seeds to small parts. If the raw material is small, we won't need
the crushing.
3.Softening:This is the special step for soybean oil making.Soybean is becoming soft after this step,so it is easier to flake cake and
press.
4.Flaking roller: To make the soybean into pieces with the thickness from 0.25-0.3 mm. This can help the soybean heating
well-proportioned and soaking well in the extraction section.
5.Dryer and cooker:Before the raw materials entering the extraction section,we need to adjust the water rate by dryer.In this process,
the water and temperature help to get crude oil easily and improve the quality of cake and oil.After the dryer and cooker under
105-110°C, the water content is 5-8%.
6.Pressing or pre-pressing:If the capacity is small and without extraction section, usually we will use pressing to get crude soybean
oil.Usually soybean oil making will not use press, because the oil rate is low of soybean. After cooker,soybean will direct to extraction
and get crude soybean oil.
