Peanuts occupy a large proportion of the edible oil market. The pressing process is a traditional and common peanut oil processing method, but it cannot fully extract the oil, leaving a relatively high residual oil in the cake. This has little impact on small and medium-sized oil mills, but for large edible oil processing plants, it is crucial to fully utilize oil resources to reduce production costs and increase profits, allowing the oil plant to stand firm in the fierce market competition. Therefore, in large peanut oil processing projects, the pre-pressing and extraction process is chosen to produce peanut oil to improve the oil yield.

Huatai's pre-pressing and extraction production line is renowned in the field of large-scale peanut oil processing equipment for its high output and high oil yield. Here is a detailed introduction to this production line:

The Huatai pre-pressing and extraction production line is an automated production line that integrates oilseed pretreatment, pressing, extraction, refining, and filling. This production line is suitable for large edible oil processing plants, fully leveraging the advantages of the pre-pressing and extraction process to increase oil yield and reduce production costs.

Components of the Production Line:

Pretreatment Equipment:

Used for cleaning, shelling, and crushing peanuts to prepare for subsequent pressing and extraction steps. These devices can alter the structure of the oilseeds, condense the oil, increase the oil yield, and reduce the adverse effects of solid impurities in the oilseeds on mechanical equipment.

Pressing Equipment:

Applies external force to squeeze the peanuts, obtaining initial peanut oil and pressed peanut cake. The pressing step can extract about 80% of the oil from the oilseeds, providing a basis for subsequent extraction processing.

Extraction Equipment:

The pressed peanut cake is crushed and put into an extractor, where solvents (such as No. 6 light gasoline) are used to dissolve and extract the remaining oil. The extractor usually has an annular or flat-rotating structure to ensure full contact between the solvent and the oilseeds. The extraction process can further extract the oil from the peanut cake, keeping the residual oil rate in the final peanut cake meal very low.

Separation and Recovery Equipment:

Includes evaporators, stripping towers, and condensers. These devices are used to efficiently separate the mixed oil (a mixture of solvent and oil) after extraction, recover the solvent, and obtain crude oil. The solvent is recovered and reused through the condenser, reducing production costs.

Refining Equipment:

Refines the pressed crude oil and extracted crude oil to remove impurities, odors, and solvent residues, obtaining standard-compliant peanut oil. The refining process includes degumming, deacidification, dehydration, decolorization, and deodorization, improving the quality and safety of the oil.

Advantages of the Production Line:

Huatai's peanut production line has several advantages: high oil yield, high degree of automation, energy saving and environmental protection, and customized services. Huatai Machinery provides comprehensive customized services, tailoring complete pre-pressing and extraction production lines according to the specific needs of customers (such as raw material characteristics, production scale, product standards, etc.). This ensures the applicability and flexibility of the production line. Huatai's pre-pressing and extraction production line is suitable for large edible oil processing plants with high daily processing volumes and capacity requirements. These plants can fully leverage the advantages of the pre-pressing and extraction process to increase oil yield, reduce production costs, and obtain high-quality peanut oil products.
