Vegetable oil production line includes two parts, one is pretreatment line, the other is oil press machine.
Pretreatment production line is for cleaning and adjusting texture of the materials , it can improve oil yield rate, reducing breakdown of the machines. General speaking, the pretreatment machines include Magnetic drum, Cleaning sieves seed cleaning equipment, sheller , Crusher , Flaking roll, Cooker, Softening pot , Puffing machine, and plate type drier. After pretreatment, the materials will be sent to oil expeller, then the crude oil got. Different materials have different prepress methods. We usually collocate proper press line according to the customers’ materials.
Working process:
1) Metering process: with special equipment, the stable measuring scale is used to regulate the flow and measure total production. Moreover, it can achieve accumulated measurement, transient measurement and cost accounting, with accurate measurement and high precision.
2) Cleaning process: use magnetic selector to remove iron impurity, vibration cleaning sieve to remove straw, and gravity stoner to remove stones, bricks and other impurities. The dedusting system uses single union cyclone and centrifugal fan to remove dust effectively, so as to to ensure workshop hygiene and clear light impurities.
3)Softening process: with YPHW series horizontal softening pot, material enters softening drum through feeding auger, and turns over with the rotating drum. The rotating drum is equipped with heating tube, and there is steam in the tube. When material turns over continuously with the rotating drum, soy is heated to 50-70°C and is fully softened, which can improve soy plasticity, make germ flake thin and burly and improve extraction effect. In addition, the rotating drum has the inclination of high feed end and low discharge end. According to material softening conditions, regulate the rotating speed of drum to control the softening time of material in the rotating drum, so as to achieve the best softening effect.
4) Flaking process: our hydraulic compact roller flaker can better damage the oil material cell to ensure thin and uniform flake, with high toughness and small powder.
