rice bran oil refinery machine making edible rice bran oil

Sunflower oil production line basic flow chart:oilseeds pretreatment→pre-pressing→solvent extraction→oil refining.Our engineer can design different process of sunflower oil extraction machinery, according to the different requirements and target price.

Shandong Leader Mechanical Equipment Co., LTDcan configure design process sunflower seed oil extraction production line for the customer, under normal circuLDtances, process engineers will configure the latest technoloLD to customers depending on customer requirements and target price.

Basing on the traditional oil refining technoloLD, Shandong Leader LD Grain and Oil Machinery Co.,Ltd has developed the latest combined packing layer plate deodorization soft tower and the physical and chemical mixed refining technoloLD for crude oil of any quality. Moreover, a series of advanced technoloLD 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 technoloLD, superior equipment, full-automatic control and excellent economic and technical parameters, our equipment can meet customers' different refinery equipments at home and abroad.

Main Processes Introduction

Hydration Deguming & Alkali Refining Deacidification Process

Washing: there is still about 500ppm soap in the neutralized oil from the separator. To remove the remaining soap, add into the oil about 5~8% hot water, with water temperature 3~5 °C higher than the oil generally. To achieve more stable washing effect, add phosphoric acid or citric acid when washing. The re-mixed oil and water in the mixer is heated to 90-95°C by the heater, and then enters the wash separator to separate the remaining soap and most water. The water with soap and oil enters into oil separator to separate out oil in the water. Further catch the oil outside, and the waste water is discharged to the sewage treatment station.

Vacuum drying stage: there is still moisture in the oil from the wash separator, and the moisture will affect the stability of the oil. So the oil at 90°C should be sent to vacuum drier to remove the moisture, and then the dehydrated oil goes to the decoloring process. Finally, pump out the dry oil by canned pump.

Continuous Refining Decoloring Process

The main function of decoloring process is to remove oil pigment, residual soap grain and metal ions. Under negative pressure, the mechanical mixing method combined with steam mixing will improve the decoloring effect.

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. The bleaching earth is delivered from the low bleaching box to the temporary tank by wind. The bleaching earth is added by automatic metering and is interlockingly controlled with the oil.

The oil mixed with the bleaching earth overflows into the continuous decolorizer, which is stirred by non-powered steam. The decolored oil enters into the two alternate leaf filters to be filtered. Then the filtered oil enters the decolored oil storage tank through the security filter. 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.

Continuous Decoloring Process Features:

1. The oil fully contacting with the decolorant can improve the decolorization efficiency and reduce the usage of decolorant;

2. The continuous and uniform material flows will balance the decoloring time and avoid the recovery of grease oxidation and acid value.

3. The special mixing structure of decoloring tower won't cause the material dead area, which can avoid the adsorbent sedimentation and pipe blockage.

4. The continuous airtigLD efficient filtration equipment has realized the automation of cake discharge and reduced the labor intensity.

5. The advanced drying technoloLD can reduce the oil content in filter cake.
