Problem Overview

In the modern oil pressing industry, the selection and use of oil presses has an important impact on the production efficiency and product quality of enterprises. However, faced with many different types of oil press equipment on the market, many companies have encountered difficulties in choosing equipment that suits their needs. This article will explore the characteristics and applicable scope of different types of oil presses to help companies make wise decisions.

Classification and working principle of oil press

Oil presses are mainly divided into three categories: hydraulic oil presses, screw oil presses and leaching oil presses. Each type of oil press has different working principles and characteristics and is suitable for different production needs.

1. Hydraulic oil press

The hydraulic oil press mainly uses the hydraulic principle to inject high-pressure liquid into the pressing chamber, so that the oil crops are squeezed out of oil under high pressure. This equipment is easy to operate and has a high oil yield, usually up to 90% or more, but it is noisy and has poor adaptability to different types of oil crops.

2. Screw oil press

The screw oil press uses a rotating screw to squeeze oil crops, and the oil crops are squeezed under high temperature and high pressure conditions to produce oil. The screw oil press can operate continuously and efficiently, has strong adaptability, and is suitable for a variety of soft-shell and hard-shell oil crops, but its oil yield is relatively low, usually between 60%-70%.

3. Extraction oil press

The oil extraction press uses solvent to extract oil. The oil in the oil crops is fully mixed with the solvent by injecting the solvent, and then the solvent is recovered through evaporation, separation and other processes to finally obtain the oil. This type of equipment has a high oil yield, but it is necessary to pay attention to the problem of solvent residue and high energy consumption.

Advantages, characteristics and selection factors of oil press

When choosing an oil press, companies need to comprehensively consider factors such as the oil rate, energy consumption and applicable scope of different equipment to achieve the best economic benefits.

1. Oil rate

The hydraulic oil press has the highest oil yield, which can reach more than 90%; the screw oil press is second, with an oil yield of 60%-70%; the leaching oil press has the lowest oil yield, about 40%-50%. Different types of oil crops have different oil yields in different equipment, so you should choose the right equipment according to your specific needs.

2. Energy consumption

Hydraulic oil presses have lower energy consumption because their working principle mainly relies on hydraulics; screw oil presses have relatively higher energy consumption, but still lower than leaching oil presses, which require a large amount of solvent and have the highest energy consumption.

3. Scope of application

Hydraulic oil press is suitable for hard-shelled oil crops, such as peanuts and sesame; spiral oil press is suitable for soft-shelled and hard-shelled oil crops; extraction oil press is suitable for various oil crops, but attention should be paid to the problem of solvent residue.

Solution: Reasonable selection, optimized production

Reasonable selection of oil pressing equipment according to the production characteristics and market demand of the enterprise can greatly improve production efficiency and economic benefits.

1. For high oil rate requirements

For enterprises with high oil rate requirements, hydraulic oil press is an ideal choice, especially for hard-shell oil crops that require high oil utilization rate.

2. Wide adaptability of screw oil press

For enterprises that want equipment that can adapt to a variety of oil crops and consider continuous and efficient operation, the screw oil press is a more balanced choice.

3. Considering the solvent residue of the leached oil press

For companies that need high oil yields and do not mind energy consumption, an oil extraction press can significantly increase oil extraction rates, but measures must be taken to deal with solvent residues.

in conclusion

When choosing oil pressing equipment, enterprises need to comprehensively consider factors such as oil yield, energy consumption and applicable scope, and reasonably select equipment types in combination with their own production needs and market positioning to improve market competitiveness and production efficiency. Through scientific and reasonable equipment selection and management, enterprises can occupy a favorable position in the fierce market competition and achieve sustainable development.
