Definition

What is peanut oil refining process?

The crude oil obtained either from expellers or solvent extraction plant contains impurities, which must be removed to make the oil edible, more palatable and stable against rancidity upon storage. The process of removing these impurities is called refining.

Classification of peanut edible oil refinery:

In operation type:

A. Batch Type B. Semi-continuous Type C. Full Continuous Type

In technology :

A. Chemical Type B. Physical Type C. Both Chemical And Physical Type

Batch Type

Adapt to 1-10t/d small capacity

plant

Semi-continuous Type

Adapt to 10-30t/d medium capacity plant

Continuous Type

Adapt to 30t/d and above capacity plant

What is peanut oil refining process Process?

Step 1.Degumming with water to remove the easily hydratable phospholipids and metals.
Step 2.Addition of a small amount of phosphoric or citric acid to convert the remaining non-hydralable phospholipids (Ca, Mg salts) into hydratable phospholipids.
Step 3.Neutralising of the free fatty acids with a slight excess of sodium hydroxide solution, followed by the washing out of soaps and hydrated phospholipids.
Step 4.Bleaching with natural or acid-activated clay minerals to adsorb colouring components and to decompose hydroperoxides.
Step 5.Deodorising to remove volatile components, mainly aldehydes and ketones, with low threshold values for detection by taste or smell. Deodorisation is essentially a steam distillation process carried out at low pressures (2-6 mbar) and elevated temperatures (180-220°C).

Introduce peanut oil refining process

Basing on the traditional oil refining technology, LD LD Grain & Oil Machinery Co., Ltd has developed the latest combined packing layer plate deodorization soft tower and the physical and chemical mixed refining technology for crude oil of any quality. Moreover, a series of advanced technology 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 technology, superior equipment, full-automatic control and excellent economic and technical parameters, our equipment can meet customers' different refining requirements at home and abroad.
LD company can provide you with the design, installation and manufacturing of 50~1000T/D oil refining production line.

peanut edible oil refinery Refining Tank

Under 60-70℃,it occurs acid-base neutralization reaction with sodium hydroxide ,After stirring by reduction box, it can decrease the acid value in oil and separate the impurity .The oil can be refined further.

Decoloration Tower

Also named bleaching, dewatering pot, it removes water from oil by vacuum. The bleaching earth is breathed into bleaching pot ,after stirring, filtrated by filter and change the color of the oil.

peanut oil refining process Deodorization Tower

The qualified decolored oil enters into the spiral plate heat exchanger to recover most of the heat, and next goes to high pressure steam heat exchanger to be heated to the process temperature (240-260℃) and then enters the deodorization tower. The upper layer of combined deodorization tower is the packing structure which is mainly used to remove the odor producing components such as free fatty acid (FFA);

peanut oil refining process Deodorization Tower

The bottom layer is the plate tower which is mainly for achieving the hot decoloring effect and reducing the peroxide value of the oil to zero. Oil from the deodorization tower enters into the heat exchanger to recover most of the heat and makes further heat exchange with crude oil, and then is cooled to 80-85℃ through the cooler. Add the required antioxidant and flavor agent, and then cool the oil below 50℃ and store it.

peanut oil refining process Leaf Filter

Equipped with vertical leaf filter to remove used bentonite from the oil, operating conveniently and continuously , low laboring tense, keeps environment well, keeps oil residence in deposable bleaching earth in low level.

To keep the whole plant running continuously, we match with 2set of trade off leaf filter. When one filter was filled full, and the other instead of.

peanut oil refining process Centrifuge

Electric control system:
1.Automatic deslagging,which include part deslagging and full delagging;
2.Schneider touch screen dispalyer and Simens PLC.DP connector to transport data;
3.The operation time of the centrifugue is showed and accumulative by the automatic control director.

2. High oil refining rate peanut oil refining process is driven by rack, with unique rotor of balanced design, low rotating
speed, low power, smooth operation, no noise and quite low maintenance cost;
3. The feeding system can adjust the rotating speed of airlock and main engine according to the
feeding quantity and maintain a certain material level, which is beneficial to the micro negative
pressure inside the extractor and reduce the solvent leakage.;
AAA1
The advanced High oil refining rate peanut oil refining process is designed to reduce the fresh solvent inputs,
reduce the residual oil in meal, improve the miscella concentration and save energy by reducing
the evaporation capacity;
The high material layer of the extractor helps to form immersion extraction, reduce the meal
quality in miscella, improve the quality of crude oil and reduce the evaporation system scaling;
Specially suitable for the extraction of various pre-pressed meals.
