What kinds of crude palm oil filter machine can be chosed?

After the main process of sterilizing, threshing, deigesting and oil pressing, we can get crude palm oil (cpo) and the mixture of palm nut and fiber. Crude palm oil contains a lot of water, as well as colloid, pulp and other impurities, which must be remove. Otherwise, it is easy to cause the crude palm oil go bad. Traditional palm oil purification equipment includes oil tank, drying oven and filter press. This kind of equipment combination is complicated, costly and needs large space occupation, making it unsuitable for small scale palm oil extraction production. How to choose suitable oil filter machine for palm oil production production process? What kinds of palm oil filter machine can be used in palm oil production process? Please continue reading you will find the answer.

What kinds of crude palm oil filter machine can be choosed?

With the development of palm oil processing technology, there are various kinds of oil purifier and oil filter press. Their functions and application fields are also different. Now, let’s focus on how to select the most suitable crude palm oil purifier or filter press according to the characteristics of palm oil production process.

Main crude palm oil filter press machines are as follows:

Type 1: Plate type filter press machine

Working Principle:

With traditional oil filtering process, the fiber and some coarse particles can be filtered through prefilter. The filtered crude palm oil is transported by the oil pump into a small plate-frame filter press. After pressure filtration, the solid impurities and water in the oil are intercepted on the filter cloth, and a small amount of water is absorbed by the filter cloth.

Notes: As the crude palm oil contains lots of impurities, the filter cloth needs to be replaced frequently, and replacing the filter cloth needs to stop operation. The operation process is relatively tedious. Besides, during the filter pressing process, the filter cloth can only absorb a small amount of water in the oil, and cannot effectively reduce the moisture content.

Type 2: Automatic leaf filter press machine

The automatic leaf filter press machine is composed of shell, filtration plate , cover, and automatic vibration device. Among them, the filtration plate is made of many layers of stainless steel filtration materials, and they are installed on the central liquid collection pipe. So it can be dismantled for cleaning very conveniently.

Working principle:

The main body of the filter is made up of vessel, filter screen, lifting structure and automatic discharging device. Filterscree are made by material of multilyer stainess steel which installed at the center collection pipe and cleaned up conveniently . In the process of filtration, the unfiltered liquid with filter aid come into the body through transmission system. After a stable filter cake formed on the filter gauze flakes, the filtrate are filtered through the micropores of filter cake.

Type 3:Vacuum oil filter press machine

Working Principle:

With vacuum oil-filter, the air in the filtering tank is pumped out by the vacuum pump to form a vacuum environment. Under the action of atmospheric pressure, the crude oil enters the primary filter through the inlet pipe, and the larger particles will be cleared. And then the oil enters the heating tank, the oil is heated to around 40~75℃ and then go through the automatic oil drift valve which is automatically controlled to balance the oil in and out in the tank. The heated oil spins rapidly through the spray wing, making the oil into a semi-mist state. The water in the oil evaporates rapidly into steam and is continuously sucked into the condenser by a vacuum pump. The water vapor in the condenser is cooled and then be turned into water again and discharged. This is the whole process of vacuum oil filter to remove impurities, moisture and gas. Purified palm oil is finally got.

Tips: When the filtering cloth absorbs too much impurities, the pressure in the vacuum tank will increase, and the filter paper needs to be replaced in time. Due to the high impurity content of crude palm oil, this type of filter press machine also needs to change the filtering cloth frequently, which is not good for continuous operation.

Type 4: Centrifugal Oil Filter press machine

Working Principle:

When using centrifugal oil filter machine, the crude palm oil is rotated at high speed. The oil, water and impurities can be separated rapidly by different centrifugal forces to achieve the aim of separating, delaminating or settling solids in liquid. The separated impurities are attached to the impurity collecting cover. You only need to clear the cover regularly. In addition, because the density of water is higher than that of oil, under the action of centrifugal force, water is separated from the oil and stored in the dish in the rotor, and can be cleaned easily. The separated oil flows out directly through gravity.

Centrifugal Oil Filter press machine

To sum up, all kinds of crude palm oil filter press machines have different characteristics. They have different advantages and disadvantages for crude palm oil clarification station. In order to get purified palm oil, vacuum oil filter presss machine and leaf filter press machine is suggested. If the budget is limited, vacuum oil filter should be a good choice, which also matches with small scale palm oil processing machinery.
