This 50tpd continuous palm oil refinery plant is designed for continuous operation. Continuous palm oil refinery plant is recommended against the batch refining for higher capacity plants above 30 tons per day and for oils containing higher FFA content. This continuous palm oil refinery plant is bit expensive than batch type palm oil refinery plant, but it provides superior quality refined oil along with automation system and low processing cost.
Company is a leading designer, manufacturer and exporter of edible oil refinery plant in both continuous type vegetable oil refinery plant and batch type vegetable oil refinery plant. It is very essential that the crude oil obtained from oil press workshop and solvent extraction workshop get refined in the vegetable oil refinery plants before it is utilized directly. Our continuous vegetable oil refinery plant gives color uniformity and appealing quality to the oil by removing unpleasant smell and undesirable factors from the oil.

Mian process of 50tpd continuous palm oil refinery plant:
(1) Neutralization section:
During the neutral section, put the degummed oil with appropriate temperature and the appropriate concentration of alkali liquor into the centrifugal mixer, in order to achieve the best effect, the mixture is then sent to neutralization tank for enough time, in the process, liquid alkali saponification soap free fatty acid formation, and within the neutralization separator is separated.Formation soapstock also played an adsorption oil soapstock other impurities, and the function of color pigment.In order to enhance the separation effect, the mixture of oil/soap in neutralizing heater is heated to reduce its viscosity.
(2) Washing process:
The separated Neutralized oil still contains about 500 ppm soap; In order to reduce the residual content of soap, oil is joined by about 5% of hot water, and washed in the washing mixer, hot water will absorb oil soap and other impurities, remaining in the water separator are then separated.
(3) Vacuum drying section:
Output oil from the water washing neutralizing and washing oil separator, still contains some unfavorable to the stability of remaining water, in order to remove the residual moisture, oil was about 110-120 degrees, was taken to the tower of vacuum drying/desolventizing dehydration, drying oil is pumped directly into the decoloring process.In addition, at this stage to produce GB standard Class 3 cottonseed oil, Class 4 of rapeseed oil.
(4)Decoloration section
The decolorration section aims to remove pigment existed in the crude oil, soap residue in the oil and so on. Decolorization process includes the following stages:
a: Decoloration
Under steady flow control, oil uses low pressure steam and oil heater heating to 105 degrees. The heated oil is then sent to the vacuum bleaching tower.When oil enters the bleaching tower, mix with the clay through a mix ratio. Clay transport system used in the ground between the white folk to the clay storage, flowing into bleaching tower above of storage tanks.Bleaching tower is separated into several layers, each layer is equipped with a steam ejector, which is used for mixing oil and clay, the residual soap in the oil, gum precipitation, plastid and other metals has also been absorped by the bleaching earth.
b: Filter:
Oil from bleaching tower, mixed with clay, then pumped into the decoloring filter, and then enter the fine filter, clay and solid impurity is blocked here, filter (decoloring oil) is then transferred to the decolorizing intermediate storage tank.
Two decoloring filters are in this system, there is always one filter in filtering state, the other is in a state of empty and clean. When in the period of emptying and cleaning filter pressed by steam, so most of the oil in the filter is blowed to the decoloring oil tank, a small number of oil mixed with clay was discharged into steam cyclone and slop tank, filter cake blow dry steam; In the filter drying period, slop tank is also filling with leftover oil and condensate, finally the dry cake is at the bottom of the filter through the discharge valve, making use of pneumatic vibrator is fallen into the waste clay room.
The rest slop is pumped back to bleaching tower and be reprocessed.
(5) Deodorization section:
Deodorization section aims to remove free fatty acids, small molecules that exist in the decoloring oil material, etc. It includes the following stages:
a: deaerator
From filter decoloring oil is stored within the decoloring oil tank, the tank is designed to work in the vacuum condition; from this tank, decoloring oil is pumped into the vacuum state analysis of the deaerator, release out the empty air in the oil.
b: Heat:
Entering the deodorization period of decoloring oil flow rate is controlled by a flow controller, oil is through a series of heat exchangers and heated to about 250-200 degrees of deodorization temperature:
When oil is heating in the final oil heater, part of the free fatty acids of low boiling point here and some of the volatile matter is evaporated, gas and liquid oil enters into the padding type deodorization tower from different entrances.
c: Deodorization:
After heating oil in flash tower, main deodorization tower, retention tank to distillation, vaporization and odor components of fatty acid in oil are removed.
d: Fatty acid recovery
In the washing area, the recycling of free fatty acid distillate flowing downwards from the top, which is often used to condensat rising free fatty acids and other condensate in the air. Condensation of distillates are collected in the temporary storage tank, the fatty acids are recycling: cooling in fatty acid distillates cooler, then recycled to the top of the fatty acids trap. Fatty acids temporary storage tank of liquid level is controlled by manual.
To reduce the quantity of fatty acid drops within air goes into the vacuum system and circular water pool, we installed a demister on the capture.
e: Heat-exchange and cooling
From deodorization tower, through deodorization pump to raw out the smelly oil, and then through the oil heat exchanger cooling by the incoming of decoloring oil, and then into the oil cooler, cooling by cooling water to the storage oil temperature,; finally through the fine filter for fine polishing filter, and then are fed into the product tank.
