Vegetable oil processing

Vegetable oil 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. At higher temperatures, phospholipids burn to contact surfaces and thus hinder both edible oil refining process and uses for biofuel purposes.

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. Dewaxing leads to a purer and tastier oil.

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.

Vegetable oils 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.

Automatic filtration

The product automatic filtration is designed for vegetable oil filtration, especially for the removal of solids, which are introduced during oilseed pressing. This technology is offered for middle- and large-scale press shops.

Plate filters

Plate filters represent an optimized solution for small-scale and middle-scale press shops. These filters offer superb filtration parameters at low running costs and purchase price. Maintenance of our filters is made easy thanks to their simple yet extremely robust design.

Processing of used kitchen oils

Used cooking oils are a waste product in the food industry and their using can be found in many other fields: construction, forestry, energy, biodiesel component.

UCO – Used cooking oil

Technology UCO is an ideal opportunity to achieve high profitability. During process we don’t use any chemicals; the technology is based on purely physical processing including the use of heat recovery.
