MAIN PROCESS OF LD CONTINUOUS REFINING:
WHAT WILL BE PRODUCT OIL LIKE?
ABOUT REFINING:
Oil refining is a complicated process normally including physical and chemical refining. An optimization refining process is the essence of the oil production. According to different physical and chemical characters of the oil and accompaniment, separate oil and impurities with the help of acid, alkali, high temperature process, ect. to improve the oil stability and safety for using and storage. Our main oil refining process as follows:
1) Intermittent Refining Process
Itâs suitable for small scale oil refining plant. Itâs major process including degumming, deacidification, bleaching, deodorization.
2) Semicontinuous Refining Process
Itâs major process including degumming, deacidification, bleaching, deodorization.
3) Continuous Refining Process
Itâs suitable for large scale oil refining plant. The major process including degumming and alkali refining, deacidification, water washing, drying, bleaching, filtration, deodorization.
Hydration Deguming & Alkali Refining Deacidification Process:
Neutralization: the crude oil is output by the oil feed pump from the oil tank, and next enters the crude oil heat exchanger to recover part of heat after metering and then is heated to the required temperature by the heater. After that, the oil is mixed with the metered phosphoric acid or citric acid from phosphate tank in the gas mixture , and then enters the conditioning tank to make
the non-hydratable phospholipids in oil change into the hydratable phospholipids. Add the alkali
for neutralization, and the alkali quantity and alkali solution concentration depend on the quality of the crude oil. Through the heater, the neutralized oil is heated to the temperature (90°C) suitable for centrifugal separation to remove the phospholipids, FFA and other impurities in the crude oil. Then the oil goes to the washing process.
Decoloring Process: The main function of decoloring process is to remove oil pigment, residual soap 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.
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 airtight efficient filtration equipment has realized the automation of cake discharge and reduced the labor intensity.
5. The advanced drying technology can reduce the oil content in filter cake.
Deodorizing Process:
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°C) 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); 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°C through the cooler.
Add the required antioxidant and flavor agent, and then cool the oil below 50°C and store it. Such volatiles as FFA from the deodorizing system are separated by the packing catcher, and the separated liquid is FFA at low temperature (60-75°C). When the liquid level in the temporary
tank is too high, the oil will be sent to the FFA storage tank.
Automatic control System:
Our company has applied the automatic control system with advancedness, security, reliability into the pretreatment, extraction, refining and fractionation in large oil plants. For its application in automatic control system, it can control the production in the entire workshop and monitor the operational status of each device by controlling the computer terminals in the room. One person only can operate the entire workshop, with efficient production management. It has reduced the production cost greatly and improved the management efficiency.

At present, LD hot sale refined rice bran oil making line, Refined rice bran oil making machinery is the most advanced oil press equipment in oil extracting and processing
machine. Small scale oil extraction machine is through forced feed by a screw shaft which
produce high temperature and pressure under the rotation and squeeze between screw shaft and
pressing ring. It is a extracting oil technique that make materials from crush and squeeze to
oil and cake, which belongs to physical press.

Introduction of LD hot sale refined rice bran oil making line, Refined rice bran oil making machinery
1)Palm oil mill have main ten parts: Reception Station,Sterilizer,Threshing,Press,Clarification,
Kernel Recover, power station, boiler station, water treatment plant, oil storage tank.
2)LD hot sale refined rice bran oil making line, Refined rice bran oil making machinery use the Fresh Fruit Bunch, because the palm fruit rancidity is very fast, if the
rancidity will be influence the palm crude oil acid value, if the acid value is very high, the
refining efficiency will drop.
3)Generally speaking, the palm oil mill be mainly located in Nigeria,Malaysia,Indonesia etc..
