How to Choose the Cooking Oil Extraction Equipment Manufacturer ?

The extractor is the core equipment in the oil extraction process, and its quality directly affects various economic and technical indicators of production. Therefore, the proper selection of an extractor is crucial for improving production efficiency, reducing costs, and enhancing the economic benefits of an oil extraction plant.

Complete oil extraction production line can be divided into three stages from raw materials to finished oil:

Raw Material Pretreatment 

This stage involves cleaning, de-stoning, crushing, cooking, and expanding the raw materials. The equipment needed varies depending on the type of raw material. For example, in rice bran extraction, the expansion extraction process is usually adopted, which better modifies the structure of rice bran for improved oil extraction. Common equipment includes vibrating cleaner-de-stoners, crushers, flaking machines, expanders, and steam cookers.

Oil Extraction 

During this stage, extraction equipment uses solvents to fully contact the pretreated oil materials, extracting the oil to form miscella. The solvent and oil are then separated based on their different boiling points through evaporation, stripping, condensation, and recovery, resulting in crude oil and recyclable solvent. A complete extraction system typically consists of meal extraction, wet meal desolventizing, mixed oil evaporation, and solvent recovery systems.

Crude Oil Refining 

Extracted oil must be refined to remove impurities and control solvent residue to a safe level for human consumption. Refining equipment generally includes degumming, deacidification, dehydration, decolorization, and deodorization systems. For certain oils like rice bran, tea seed, and walnut oil, an additional dewaxing process is required after deodorization. Refined oil goes through quality inspection and is then packaged and stored for sale in supermarkets as edible oil.

Oil extraction production line is a relatively large investment, requiring high standards for equipment quality and safety. Therefore, customers should carefully compare and evaluate manufacturers to find the one that best suits their needs.  Huatai Cereals And Oils Machinery Co.,Ltd . provides greater assurance in terms of design solutions, equipment quality, and after-sales service.
