Frame-plate filter FPR-32 for the purification of vegetable oils

Frame-plate filter FPR-32 for the purification of vegetable oils is an efficient device intended for the filtration of vegetable oils at the stage of their purification after the pressing process. It effectively removes fine mechanical impurities, sediments, particles of plant tissues, and waxy substances, improving the clarity and quality of the finished product.

Thanks to the use of 32 filter plates, the FPR-32 model offers a larger filtration area than smaller models from this series, which allows the operating cycle to be extended and the amount of purified oil to be increased without reducing filtration efficiency. The device is used both in oil pressing plants and in plants involved in the processing of oilseed crops.

Construction and filtration process

The filter operates based on proven frame-plate filtration technology. Oil pumped by the pump flows through the system of plates and filter cloths of the "belting" type, where all mechanical impurities are retained. The purified product then goes to the receiving tank, while the sediments remain on the surface of the filter material.

The filter elements are made of food-grade polypropylene resistant to the effects of vegetable oils. The plates are pressed by a manual screw mechanism, which ensures the tightness of the entire system during operation. The filter is equipped with a NOVAX 25 Oil pump, intended for the transfer of edible oils.

The device can work with food-grade drums with a capacity from 1000 liters. At the customer's request, it is possible to prepare a set with other tanks adapted to the production requirements.

Filtration capacity

The approximate filtration capacity of the FPR-32 filter is 150–350 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

FPR-32 is intended for the purification of vegetable oils before storage or further processing. The device performs well in the production of edible oils, where effective removal of impurities formed during pressing is required.
