Maximizing Oil Extraction Efficiency: The Art of Pre-Pressing in Edible Oil Production

2024-11-14

Oil pre-pressing is a key step in edible oil production. It involves feeding pre-treated raw materials into a press to extract crude oil. Different raw materials require different pressing equipment. We will configure equipment and processes according to the specific needs of customers. The following is a detailed introduction to oil pre-pressing and our company's advantages in this process:

Introduction to Oil Pre-pressing
Pre-pressing and pressing: Pre-pressing is part of the pressing process. After the raw materials are pre-treated, crude oil is extracted through the press.
Oil pressing method: According to the type of oilseed, oil pressing is divided into pre-pressing and pressing (including cold pressing and hot pressing).
Pre-pressing machine function: The pre-pressing machine can extract about 70% of oil from oilseeds, and the remaining cake/meal oil content must be less than 20%.
Pre-pressing requirements: Whether pre-pressing is needed depends on the oil content of the oilseed.
Oilseed classification
Oil pre-pressing: Applicable to oilseeds with an oil content of ≥20%, such as sunflower seeds, peanuts, rapeseed, cottonseed, etc.
Oil solvent extraction: Applicable to oilseeds with an oil content of <20%, such as soybeans, rice bran, etc.
Equipment related to oil pre-pressing
Oil press: mainly oil press, for example, palm oil press is different from conventional oil press.
Advantages of oil pre-pressing process
Multi-oil processing: can process a variety of oils, including peanuts, rapeseed, cottonseed, sunflower seeds, sesame, etc.
Puffing process: according to customer needs, puffing process can be used to save energy and obtain high-quality oils.
Multi-stage filtration: pre-pressed oil adopts multi-stage filtration to ensure the purity of oil.
Strong adaptability to raw materials: strong adaptability to raw material quality, able to handle oils of different qualities.
