Oil frame filter press always be used as a oil purifier in the oil plants for edible oil or biodiesel. This model filter is suitable for filter crude oil and refined oil, and it is also can be used to filter bleaching oil in the refining workshop.

Crude (freshly extracted) oil contains moisture, and fiber, resins, colors etc. from the plant material, which make it darker and more opaque. These materials are removed by clarification – either by letting the oil stands undisturbed for a few days and then separating the upper layer, or by using an oil frame filter press. The oil is filtered through a cloth and heated briefly to 100°C to boil off any remaining traces of moisture. This is usually sufficient to meet the quality needs of customers and give a shelf life of several months when correctly packaged. However, the oil requires additional Edible Refining Stages of de-gumming, neutralising and de-colouring to have a similar quality to commercially refined oils, and these stages are difficult to complete at a small scale.

Our oil frame filter press is characterized by convinient operation, stable technical effect, high capacity and low impurity.
