How Oil Extraction Machine Works?

Oil press machines are essential for producing healthy vegetable oils. But how oil extraction machine works? Let’s take a closer look.

What Is An Oil Press Machine?

An oil press machine is allotted for this process, whereby oil is extracted from the plant or fruit. The primary sources for these are food items like peanuts, soybeans, sesame seeds, coconuts, and olives, for instance.

It is the force of the press that is so great. Whether it is a hand grinder or an electric press, this pressure will break the plant cells, and the oil will be pushed out. However, the oil that the plant yields is then retrieved and stored for future processing.

How Oil Extraction Machine Works? Full Guide:

There are two main types of oil press machines: 

Types of Oil Extraction Machine1. Expeller Press Machines:

Do it with a periodic gnawing and scraping process.

Groundnuts or kernels will be pounded into paste.

The oil then gets squeezed out when the metal plate rests on the surface of the two paste pieces.

2. Hydraulic Press Machines:

Utilize the compressive force of intensity.

A compressor can process peas or nuts at the same time.

The oil comes through small pores somewhere.

How Does An Expeller Press Work?

One of the key components of an expeller press is the effect of pressure.

1.  It uses a constant churning and grinding motion

2.  Seeds or nuts get crushed into a paste

3.  Paste gets compressed to squeeze out the oil

4.  The revolving shaft creates such a large pressure on the coal bed.

5.   The oil squeezed out of it forms the paste.

6.   The liquid oil comes out in small amounts through tiny holes in the well.

The rest of the particulate material that remains goes into the waste line.

Expellers range in size from miniature household devices to large industrial-scale units.

How Does A Hydraulic Press Work:

1. Hydraulic presses use brute force instead of churning.

2. The collector holds the seeds and/or nuts in its chamber.

3. A hydraulic ram applies immense pressure to fall right onto the ground.

4. It crushes the plant mass completely.

5. Oils are obtained by pressing them through pipes or meshes.

6. It is the remaining seed cake that is cleaned off for this process.

Usually, hydraulic presses are less effective than expellers. On the contrary, they are oil-extracting.

Oil Extraction Process:

Once extracted, the raw vegetable oil still needs additional processing:

1. Filtration:

Channels any solids or particles.

2. Purifying:

Compounds that are not wanted get separated.

3. Decolorization:

Oil loses its color.

4. Deodorizing:

Removal of offensive odors and flavors

5. Storage:

 It is put in storage until used or sold.

It is only at this point that the vegetable oil is fine-tuned, ready for either household or industrial use.

Environmental Impact:

1. Compared to chemical extraction methods, mechanical oil presses:

2. Solvents should not be harshly used.

3. Minimize toxic waste production.

4. Influence the crops to yield oils of higher quality.

5. Reduce environmental pollution.

Additionally, the rest can serve as feedstock for livestock or biogas.

Where to Find Best Oil Extraction Machine?

Wellshop produces various types of oil presses and extractors for producing refined vegetable oil. These are available at an affordable oil extraction machine price in Pakistan. Yet this technology can also be considered eco-friendly thanks to its mighty yet oil-extracting equipment which efficiently manipulates oil from seeds, nuts, and plants using just mechanical pressure. Shop with Wellshop and have the finest oil extraction equipment.


How oil extraction machine works? Briefly, oils are extracted from the seeds of various vegetables under high pressure with the help of oil press machine. Grind and churn the seeds or nuts using expeller pressea. Hydraulic presses simultaneously compact all the cubes.

The way this pressure squeezes or ruptures plant cells to release oil is not important. Filters and sieves are then applied, turning the obtained oils into consumable goods.
