A hydraulic press is a mechanical device that is widely used to extract various edible oils from plant seeds, such as soybean oil, peanut oil, and coconut oil. It is an important pillar of the modern grease industry and is mainly divided into three types: hydraulic hydraulic press, screw hydraulic press and leaching hydraulic press.
The hydraulic press uses high-pressure liquid to squeeze out the grease in the oil crops. It is easy to operate and has high oil yield (>90%), but it is relatively noisy and has poor adaptability.
The screw hydraulic press uses the squeezing action of the screw and the pressing chamber to effectively extract grease. Although the oil yield is medium (60%-70%), its high efficiency and strong adaptability make it suitable for a variety of soft and hard shell oil crops.
The leaching hydraulic press uses solvent to extract grease and has a high oil yield (40%-50%), but attention must be paid to the problem of solvent residue. Suitable for a variety of oil crops.
Different types of hydraulic presses have significant differences in grease recovery rates and energy consumption. Hydraulic hydraulic presses have the lowest energy consumption, while leaching hydraulic presses have higher energy consumption. When selecting a hydraulic press, it is necessary to comprehensively consider the type of oil crops and extraction efficiency to ensure the economy and effectiveness of the equipment.
Understanding the working principle of the hydraulic press and its advantages and characteristics can help you make scientific and reasonable choices in the oil extraction process. Choosing a suitable hydraulic press will directly affect the production efficiency and cost-effectiveness of grease.
