How to Establish a Peanut Oil Processing Plant from Scratch?

I. Market Research and Pre-Project Planning

1. Market Demand and Positioning Analysis

• Consumer Trends: Investigate the demand ratio of premium fragrant peanut oil (hot-pressed) versus refined peanut oil in your target market. In mid-to-high-end markets, green and organic "low-temperature cold-pressed peanut oil" commands a higher premium, whereas "hot-pressing technology" with higher oil yields offers a significant price advantage in mass consumer markets.
• Competitor analysis: Evaluate competitors' product specifications, packaging sizes, price ranges, and primary sales channels in the local market to identify your "differentiation" strategy.

2. Factory site selection and scientific layout of workshops

• Geographical Location: It is highly recommended to prioritize locations near major peanut-producing regions or large logistics hubs. Peanut raw materials are bulky, and being close to the production origin significantly reduces operational expenses (OpEx) while ensuring the freshness of the raw materials.
• Workshop Layout (Avoiding Cross-Contamination): Design a unidirectional flow strictly according to the processing sequence. The factory should be divided into: Raw Material Storage, Pretreatment Workshop, Pressing/Solvent Extraction Workshop, Refining Workshop, and Bottling & Finished Product Warehouse. Each area must be strictly isolated to ensure food safety compliance.

3. Capital Budgeting and Working Capital Control

The investment budget should be clearly divided into two main components: Fixed Asset Investment (land, workshop construction, full sets of equipment, power distribution facilities) and Working Capital (raw material procurement, solvents/auxiliary materials, labor, and operational costs for the first 3 months). It is advisable to reserve a 10%–15% contingency fund.

II. Core Processing Routes: Cold Pressing vs. Hot Pressing vs. Pre-Pressing & Solvent Extraction

The method of oil extraction directly determines your plant scale, equipment investment, and the quality of the final product. A comparison of the three mainstream international processing routes includes:

• Fragrant Hot Pressing: Raw materials are pressed after high-temperature steaming and roasting.
  Advantages: This method maximizes the unique rich aroma of peanuts and achieves a relatively high oil yield. It is highly favored in Asian and African markets.
• Low-Temperature Cold Pressing: Raw materials are mechanically pressed at room temperature or low temperatures (<60°C).
  Advantages: It perfectly preserves the vitamin E and active nutritional components in peanuts. It is natural, healthy, clear in color, and ideal for the premium bottled oil market.
• Pre-pressing & Solvent Extraction: Suitable for large-scale industrial oil plants (>50 TPD). The peanuts undergo light mechanical pressing to extract a portion of the oil, followed by solvent extraction (such as using hexane) on the oil cake.Advantages: Extremely high oil yield, residual oil content in cake can be ≤ 0.8% , Under economies of scale, the processing cost per ton of oil is exceptionally low.

III. Equipment Selection and Standard Configuration Table

The degree of automation, energy consumption, and oil yield of peanut oil processing equipment directly impact the plant's profitability. QIE Group recommends the following standard configurations based on different investment scales:

IV. Modern Peanut Oil Production Process Flow

A complete modern peanut oil production process requires the following standard physical and chemical treatment procedures:

1. Cleaning: Utilizing vibrating screens, de-stoners, and magnetic separators to thoroughly remove impurities such as dirt, stones, iron filings, stems, and leaves from the raw materials, protecting subsequent equipment from wear and tear.
2. Shelling and Red Skin Removal: Using professional shelling machines to separate the peanut shells. The shell-to-kernel ratio is kept within a reasonable range to prevent excessive oil absorption by the shells, which lowers the oil yield.
3. Crushing & Flaking: Crushing the peanut kernels into appropriate particle sizes and rolling them into thin flakes through a flaking machine to break down the cellular structure of the peanuts, making the oil easily releasable.
4. Cooking/Roasting: Adjusting the temperature and moisture content of the material. For the hot-pressing process, high-temperature cooking is applied at this stage to aggregate the oil and generate a rich aroma.
5. Pressing/Extraction: The prepared material enters the press to separate crude peanut oil from the peanut cake.
6. High-efficiency refining: The crude oil undergoes degumming (removing phospholipids), deacidification (removing free fatty acids), decolorization (absorbing pigments via activated bleaching earth), and deodorization (high-vacuum distillation to remove odor substances) to obtain finished Grade 1 peanut oil that meets national and international standards.
7. Precision filling: Following blow molding, precision weight filling, automatic capping, inkjet coding, labeling, and boxing, the products enter the finished product warehouse.

V. Quality Control, Safety Management and Staffing

• Technical and Employee Training: Plant operations require skilled equipment operators, mechanics, and quality control (QC) inspectors. Upon project delivery, QIE Group dispatches experienced engineers to the site to provide comprehensive training for client staff on full operations, equipment maintenance, and safe production practices.
• HACCP Quality System: It is recommended to establish a comprehensive quality tracking mechanism, conducting sample retention tests for every batch of incoming peanuts and outgoing finished oil. The workshop must be equipped with complete fire protection systems and explosion-proof electrical equipment (especially in the solvent extraction workshop).

VI. Marketing, Brand Building, and Sales Channel Expansion

1. Branding and Operation: egister an independent trademark and design packaging with high recognition. Focus on health-oriented selling points such as "pure physical pressing," "zero additives," and "non-GMO."
2. Diversified channels:
   Offline: Enter supermarkets, grain and oil wholesale markets, chain catering distribution, and corporate bulk gift customization.
   Online: Establish a presence on major e-commerce platforms and utilize short videos/live streams to showcase the factory's automated production lines, building consumer trust through high transparency.
