Introduction: How to improve oil extraction efficiency?

In the modern oil and fat industry, it is very important to choose an oil press that meets production needs. This article will analyze the working principles, oil output, energy consumption and applicable scope of different types of oil presses to help you make wise equipment purchase decisions.

Question: How to choose a suitable hydraulic press?

Whether producing soybean oil, sunflower oil or peanut oil, how to choose the right oil press from the many options is a common problem faced by oil manufacturers. There are many types of oil presses, and each type has different adaptability, oil yield and energy consumption for different oil crops, which undoubtedly increases the difficulty of selection.

Solution: Understand the characteristics of different types of hydraulic presses

Before choosing a hydraulic press, you need to have a deep understanding of the characteristics of hydraulic presses, screw presses, and leaching presses. The following is a detailed analysis.

Hydraulic press

Working principle: By injecting high-pressure liquid into the oil pressure chamber, the oil in the cells of oil crops is squeezed out using the hydraulic principle.

Oil output rate: The oil output rate of hydraulic press is generally above 90%, which is higher than other types of hydraulic presses.

Energy consumption: The hydraulic press works based on the hydraulic principle and has low energy consumption.

Scope of application: Mainly suitable for hard-shell oil crops such as peanuts and sesame.

Screw hydraulic press

Working principle: The rotating screw shaft and the inner wall of the pressure chamber are used to rupture the cells of oil crops and squeeze out the oil under high temperature and high pressure.

Oil output rate: The oil output rate of a screw hydraulic press is generally between 60% and 70%, which is slightly lower than that of a hydraulic press.

Energy consumption: This type of hydraulic press relies on the rotation of the screw, and its energy consumption is slightly higher than that of the hydraulic press.

Scope of application: Suitable for various soft-shell and hard-shell oil crops, with a wide range of applications.

Extraction hydraulic press

Working principle: Solvents are fully mixed with oil crops, and then the solvents are recovered through evaporation, separation and other processes to extract oil.

Oil yield: The oil yield of the leaching oil press is generally between 40% and 50%, the lowest cluster extraction solution.

Energy consumption: This type of hydraulic press requires a large amount of solvent and consumes the most energy.

Scope of application: Suitable for various oil crops, but attention should be paid to the problem of solvent residue.

Please refer to the following figure for comparison data of various hydraulic presses: Hydraulic press type | Oil output rate | Energy consumption | Scope of application ------------ | ------ | ---- | ---- Hydraulic oil press | More than 90% | Low | Peanuts, sesame and other hard shell oil Screw hydraulic press | 60%-70% | Medium | Various soft and hard shell oils Extraction oil press | 40%-50% | High | Various oil crops, pay attention to solvent residue

Conclusion: Choose a hydraulic press that suits your needs

Taking into account factors such as the type of oil crops, oil yield and energy consumption, choosing the most suitable oil press can significantly improve the efficiency of oil extraction. Hydraulic oil press is suitable for hard-shell oil crops and has a high oil yield. Screw oil press has a wide range of applications and continuous operation, high efficiency but slightly lower oil yield. Although the extraction oil press has the lowest oil yield, it is suitable for various oil crops and requires further treatment of solvent residues.
