Product Description

Oilseed pretreatment usually means the working procedures of detaching the impurities out of the oil material to make the oilseeds in thecondition before pressing in order to extract the most oil out. It is the first and most vital step during the whole set of oil mill plant. This is the part where the seeds are procured, cleaned, flaked, and cooked so that the oil extraction process can be carried out in a more efficient manner, so that the final output or the extracted oil is of the highest quality.

During the process of Oilseed pretreatment, a series of seed processing equipment are necessary, such as cleaning sieve, crusher, dehuller, flaker, cooker, screw extruder, dryer and oil presses. Some seeds require additional preparation beyond cleaning. Soybeans, for example, are de-hulled, heated, cracked or flaked, and sometimes extruded before entering the press. Equipment used for these types of operations can generally be obtained from most press manufacturers. A producer should identify the oilseeds they need to process in order to determine exactly what equipment will be needed. WorkGroup can always meet your cleaning and pretreatment needs!

Automatic Control System

Our company has applied the automatic control system with advancedness, security, reliability into the pretreatment, etraction, 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.

Automatic peanut oil refining equipment -Main Processes Introduction

Automatic peanut oil refining equipment Neutralization: the crude oil is output by the oil feed pump from the oil tank, and net enters the crude oil heat echanger to recover part of heat after metering and then is heated to the required temperature by the heater. After that, the oil is mied with the metered phosphoric acid or citric acid from phosphate tank in the gas miture (M401), and then enters the conditioning tank (R401) 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 (90C) suitable for centrifugal separation to remove the phospholipids, FFA and other impurities in the crude oil. Then the oil goes to the washing 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-mied oil and water in the mier is heated to 90-95C 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 90C 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.

Decoloring Process:

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