Frame-plate filter FPR-16 for the purification of vegetable oils

Frame-plate filter FPR-16 for the purification of vegetable oils is a professional device designed to remove mechanical impurities and improve the quality of vegetable oils at the purification stage. The filter effectively retains fine sediments, particles of plant tissues, waxy substances and other suspensions, thanks to which the obtained product is characterized by higher purity and better performance properties.

Model FPR-16 has been equipped with 16 filter plates made of polypropylene intended for contact with food. The design uses filter cloth of the "belting" type, which ensures effective filtration of various types of vegetable oils while maintaining ease of operation and easy cleaning of the device.

Design and principle of operation

The filtration process consists in the flow of oil through porous filter cloth mounted between the plates and frames of the filter. During the flow, all mechanical impurities are retained on the surface of the filter material, while the purified oil is discharged to the receiving tank.

The plates are equipped with special channels enabling even flow of the medium through the entire filtration system. The whole assembly is tightened with a manual screw clamp, which ensures tightness during operation. The structure has been mounted on a stable support frame, on which the pump unit is also located.

The device has been equipped with a NOVAX 25 Oil pump, intended for the transport of vegetable oils. The filter can work with food-grade barrels with a capacity from 1000 liters, and at the customer's request it can be adapted to tanks of other capacities.

Filtration capacity

The approximate filtration capacity of the FPR-16 filter is 100–300 l/h. The specified range applies to oil after preliminary settling, with a low content of impurities, when using clean filter fabric and without excessive oil viscosity. The actual capacity depends on many factors, such as the settling time of the oil, the type of seeds from which it was pressed, the oil temperature, the amount and type of impurities, the oil viscosity and the degree of contamination of the filter fabric.

In practice, good results can be achieved by filtering the oil in two stages. Immediately after pressing, the oil is still warm and has a lower viscosity, which allows it to flow through the filter material more easily and quickly. At the first stage, the main task is to remove gums, fine particles and most of the suspended matter from freshly pressed oil.

After the first filtration, it is advisable to leave the oil to settle and cool for some time. As the temperature decreases, waxes, often referred to as paraffin, begin to precipitate, while some of the fine suspended matter additionally settles at the bottom.

After settling, the oil can be passed through the filter again. The second stage additionally removes the remaining suspended matter and waxes that have precipitated during cooling. As a result, the oil becomes cleaner and clearer. In practice, this may also have a positive effect on its taste.

Before the second filtration stage, the filter material should be cleaned of accumulated sediment. In the case of larger quantities of oil being produced and when it is necessary to shorten the entire process, two filters can be used. For example, the first filter with belting fabric can be used for preliminary filtration of warm, freshly pressed oil and removal of most of the gums. The second filter, equipped with filter paper, can be used for more thorough purification of the oil after settling.

The following general principle should be taken into account: the higher the oil temperature, the lower its viscosity and the faster it flows through the filter material. The oil temperature therefore has a direct impact on filtration capacity. However, before the second stage, the settled oil should not be heated strongly, as one of the purposes of this stage is to remove the waxes that have precipitated during cooling.

Application

The FPR-16 frame-plate filter is used primarily during the purification of vegetable oils after the pressing process. The device is perfectly suited both for small oil presses and for plants engaged in the production and packaging of edible oils.
