JATROPHA OIL

Jatropha oil can be extracted from the seeds by three ways. They are: Mechanically, Chemically, Enzymatically. Here is a chart that describes the process of oil extraction from the seeds, Jatropha oil extraction chart. Below are some of the methods that are usually followed to extracts the oils from jatropha seeds.

Oil Expellers

Oil expellers’ method is also use for jatropha oil extraction. The most commonly used method is the Sayari oil expeller method. This method is also called as Sundhara oil expeller. Komet oil expellers are also used. These sayari oil expellers was developed in Nepal and is a diesel operated one. Now it is developed in Tanzania and Zimbabwe mainly for the production jatropha oil. Heavy oil expellers are made of heavy cast iron and the light ones are made up of iron sheets. Electricity driven models are also available. Komet oil expeller is a single oil expeller machine that is used not only to extract the jatropha oil as well for the preparation of the oil cakes.

Cold-press Oil Extractor

Our oil presses are ideal for anyone who desires to produce their own plant based oils for bio-fuels, culinary arts cooking or direct consumption. The Oil Press is engineered to be reliable, durable, compact, and efficient.

AG-Oil Press becomes Oil Press Company!

We are rebranding AgOil Press into Oil Press Company (mostly because “agoil press” is awkward to say out loud). Same product, same ownership, same great design, new easier to pronounce name!

Traditional Methods

Traditional methods are used in the rural and developing areas for extracting the oils. Traditional methods are simple and the oil is extracted by hand using simple equipment.

Hot oil extraction

The process of extracting the oil at high pressure is called as hot oil extraction method. Since jatropha oil can regulate the operating temperature it is extracted using the hot oil extraction method. Then the cold oil extraction method it is easy to extract the oil from the hot oil extraction since the oil flows more easily due to higher viscosity. And the press cake that remains after extracting the oil also have less oil content which might be 3 to 7 % approximately. These two reasons make the oil press method very interesting.

During the oil extraction method many stuffing of the seeds are converted into gum like substances and some non-organic substances. These are unwanted products and so they have to be refined.

Modern Concepts

Modern methods are followed to extract more oils from the jatropha seeds. In these modern concepts chemical methods like aqueous enzymatic treatment is used. The maximum yield by following this modern method is said to be about 74/5. The main idea in researching the modern concepts is to extract a greater percentage of oil from the jatropha seeds.

Jatropha Oil Uses:

01. Jatropha oil is also a kind of vegetable oil that is produced from the seeds of jatropha that has the capacity to grow in marginal and common lands.

02. Below are some of the benefits of jatropha oil.

03. Used as a alternative for diesel as a renewable source.

04. Have the properties that are similar to diesel fuel.

05. It is a oxygenated fuel and is also a eco-friendly.

06. Contains less Sulphur.

07. Can be used in the diesel engine with little modification in the engines.

08. Emission of exhaust gas is reduced.
