Oil Processing

Vegetable oil obtained through pressing or extraction contains naturally occurring undesirable impurities that prevent direct use of the oil for food and technical purposes. These impurities can be categorized according to their solubility in oil.

The particles insoluble in oil can be pieces of seeds that enter the oil during its processing. Oil-soluble substances include mainly phosphorus (bound to phospholipids), resin, pigments, wax, and volatile particles. These substances may cause undesirable colouration, unwanted odour at higher temperatures, and burning at contact surfaces, all of which hinders the use of the oil in food and technical industry. Farmet offers technological equipment for filtration and purification of the oil per customer’s wishes.

Do you seek to increase the value of your oil? You will then appreciate our technology for refining and filtration of oil. We alter this technology according to each customer’s demands and quality requirements. Do not hesitate to contact our experts, who will help you choose the best solution for you.

Refining

Vegetable oil obtained through pressing or extraction contains various unwanted impurities that naturally occur in the seeds. These substances include mainly phosphorus (bound to phospholipids), pigments, wax, and volatile particles.
Degumming
The technology of degumming offers a solution for the removal of phosphorus from crude oil. Phosphorus is bound to phospholipids, which are undesirable for further oil processing.

Bleaching
Oil bleaching is a step in the process of crude oil refining. In the bleaching technology, bleaching earth is applied to crude oil, minimizing its content of pigments (e.g., carotenes and chlorophylls), heavy metals, and the phosphorus remaining after degumming. This improves the appearance and taste of the oil.

Dewaxing
The dewaxing process is only intended for sunflower oil. This is because of the wax that penetrates the oil from seed hulls and causes higher turbidity (cloudiness) or a sediment at the bottom of the vessel.

Deacidification
The goal of deacidification is the removal of naturally occurring substances that cause unwanted smell and taste. These volatile substances vaporize at higher temperatures, then condense and stain surrounding surfaces (for example, kitchen walls). Their removal can be done using distillation columns.

Filtration

The Technology of filtration offered by Farmet represents an effective solution for removing mechanical impurities from raw oil. The equipment can be used for multiple types of oil.
