Information on Different Types Of Filter Presses

An Edible Oil Filter Press is a device that is mainly used to make oil out of edible oils like olive oil, coconut oil, corn oil, or sesame oil. It is also used to filter water. The device makes a distinction between the solid and liquid components. The solid particles are left behind while the liquid ones flow out of the top of the press.

An Edible Oil Filter Press is for separates mechanically distilled oil (from solid-liquid) & non-microbial oil, from nuts, coconut, groundnut, sesame, sunflower, canola, etc. The plates of this Filter Press Machine are so deeply recessed that a tiny chamber is left when two plates are close together. In this chamber, a solid-liquid separation occurs. Here a thin film of the solid-liquid separates the solid-liquid from the non-microbial oil.

Different Types Of Filter Presses

This type of Filters Press is very popular as it gives very good quality filtration. There are several types of filters available in the market which have their advantages and disadvantages. The basic difference among the various types of Filters Press is in their mode of operation. Some of them run on electricity and some on the magnet. So the choice of using a Filter Press depends largely on the power supply used.

Any filter press machine usually consists of three major parts: a housing or tank, a power feed tube & a high-pressure filter press. The housing or the tank houses the mechanical parts of the unit and the power tube is connected to the feeding pump through a tube. A high-pressure drive is used for driving the motor and also to separate the sludge from the oily and the dry components. A needle valve is fitted in the feed pipe of the power tube to prevent the escape of dirty gases during the working phase.

After the mechanical and the fluid parts, the filter press machine makes use of a sludge chamber to feed the separating film and to form a fine film of separation. The feed is placed between two chambers in the machine. The inner chamber is filled with a solvent that is recovered from the filtration process and the outer one is filled with dry material like gravel or sand. When the two chambers are connected, the solvent and the dry materials mix, and hence the separation takes place.


The fine film of separation then flows down into the separator and the dewatering chamber. The motor of the Filter Press machine helps in the separation of the solids. A fine film of solvent and the oil settles on the film and the process is repeated and the process continues until the desired separation occurs.
