Classification of Oil Press

Oil pressing is a crucial process in the extraction of oil from raw materials. The equipment used in this process is called an oil press or an oil expeller. There are different types of oil presses available in the market, each with its unique working principle and structural form.

Here are some common classifications of oil presses:

Water pressure oil press

Also known as a hydraulic oil press, the water pressure oil press is a replacement for the screw oil press. The hydraulic oil press belongs to static oil pressing and has low oil output. The single machine is small and has many devices that require more occupation space. The warehouse needs to be kept warm, and the operation condition is poor. However, the hydropress oil press also has the advantages of a simple structure and saving man power, making it suitable for some scattered oil plants (like tikitiki, wild oil plant) and grinding hydraulic of oil plant that needs to maintain the special flavor or nutrition. Additionally, it can be used to separate the pressing and squeezing of solid fat or wax bran.

Screw oil press

The screw oil press is a widely applied type of oil pressing equipment. It has the features of high capacity of constant production, short time of dynamic oil press, high oil output, and low labor forth, etc.

The most crucial part of the screw oil press is the pressing chamber, which consists of a pressing cage and screws spindle in the rotating cage. The working process is such that as the reducing of pressing lead and increasing of the diameter of the basic round, the space of pressing cage becomes smaller and smaller to press the materials. The pressing oil is discharged from the gap of pressing cages, and the residues are in pieces at the same time and discharged from the bottom of the spindle. The screw oil press process can be divided into three phases: the feeding phrase (pre-pressing), primary pressing (oil output), and the forming of cake (heavy press and drain oil).

New-style hydraulic oil press

A new-style hydraulic oil press has been found in the market, which has improved the disadvantages of water pressure oil press in many aspects. This machine has less power consumption and occupies a few square meters, which are connected with the computer controlling system to realize automatic production. The new-style hydraulic oil press holds the features of water pressure oil press with simple structure and long service time. All the flavor of the oil is stronger than the common oil press and does not generate foams during eating, which are greatly welcomed by the customers.

Oil presses play a vital role in the extraction of oil from raw materials. The type of oil press used depends on factors such as the type of raw material, the required oil output, and the available space. Understanding the different types of oil presses available in the market is essential in making informed decisions on the most appropriate equipment for specific oil extraction needs.
