African project involving the pressing of 100 tons of peanuts into 50 tons of fragrant peanut oil.

Homepage > Project Proposal > African 100-ton Peanut Pressing and 50-ton Fragrant Peanut Oil Refining Project

This project uses 100 tons of high-quality peanuts in Africa as raw material to produce 50 tons of fragrant peanut oil annually through pressing technology. It adopts a combination of physical pressing and refining technology to fully preserve the natural flavor and nutrients of peanuts, while meeting international edible oil standards.

Project Overview

Core technologies and processes

I. Low-temperature pressing system : The screw press operates in a low-temperature environment below 60℃ to avoid high temperature damage to the peanut protein structure. The oil yield is stable between 50% and 52% , and the acid value of the oil is ≤ 1.5mg/g .

Second and third refining processes :

Pre-filtration : 100-mesh stainless steel filter screen removes oil residue.

Winterization crystallization : waxy precipitation through stepwise cooling.

Activated clay adsorption : Decolorizes while raising the smoke point to above 230℃

III. Flavor-locking technology : Preserves the natural antioxidants in the peanut skin, and the preservation packaging extends the shelf life to 18 months .

Economic and environmental benefits

By-product utilization

After being extruded, 50 tons of peanut meal can be used as a high-protein feed ingredient, maximizing resource utilization.

Energy consumption control

The waste heat recovery system reduces steam consumption by 30% , significantly improving energy efficiency.

Environmental compliance

After three-stage air flotation treatment, the COD of the wastewater is ≤ 80mg/L , which is better than the local environmental emission standards.

Project Results Showcase

The project has achieved efficient utilization of peanut resources through advanced technology, which not only ensures the quality of the fragrant peanut oil, but also improves the overall economic benefits through the comprehensive utilization of by-products, while taking into account environmental protection requirements, providing a model that can be learned from for the peanut oil processing industry in Africa.
