In the edible oil processing industry, the price of a complete groundnut oil extraction machine is a primary concern for investors. However, there is no single, simple figure; prices range from tens of thousands to millions of yuan, depending on production capacity, process configuration, and the level of automation. This article provides a detailed breakdown of the cost factors for groundnut oil extraction machine and introduces the core strengths of an industry leader: Henan Huatai Cereals & Oils Machinery Co., Ltd.

1. Price Ranges for Complete Groundnut Oil Extraction Machine

Based on current market conditions, the price of a complete set of groundnut oil extraction machine is primarily influenced by the following factors:

1) Small-scale equipment (1–10 tons/day): Suitable for family workshops and small groundnut oil mills; prices typically range from 30,000 to 150,000 yuan. These systems usually operate in batches and feature relatively simple configurations, primarily consisting of roasting pans, screw oil presses, and basic filtration units.

2) Medium-scale equipment (10–50 tons/day): Suitable for small-to-medium groundnut oil processing plants; prices range from approximately 200,00 to 800,000 yuan. These groundnut oil production lines generally include complete sections for pretreatment, pressing, and refining, offering a higher level of automation.

3) Large-scale equipment (50–500+ tons/day): Suitable for large-scale groundnut oil processing enterprises; prices range from 1 million to over 10 million yuan. These comprehensive systems cover the entire process-pretreatment, solvent extraction, and refining-and are equipped with intelligent control systems.

It is important to note that prices vary significantly based on process configuration. Costs differ between pressing and solvent extraction processes, and the depth of refining (e.g., Grade 1 vs. Grade 2 oil) also directly impacts the required investment.

2. Why Choose Henan Huatai Oil Machinery?

Among the many manufacturers of grain and oil machinery, Henan Huatai Cereals & Oils Machinery Co., Ltd. stands out due to its deep technical expertise and exceptional product quality.

3) Large-Scale Project Delivery Capability

Huatai possesses extensive experience in large-scale, complete equipment projects. In January 2026, a large-scale, complete groundnut oil processing system (500 tons/day capacity)—designed and manufactured by Huatai-passed factory testing and was shipped to the client's site. A core component of this system is Huatai's proprietary drag-chain extractor for groundnut cake; this patented technology utilizes negative-pressure evaporation to maximize oil yield while preserving the oil's original nutritional value and flavor.

In August 2026, Huatai successfully delivered a custom-designed, complete groundnut oil refining system (200 tons/day capacity) to a client in Maoming. This system integrates advanced international physical refining processes-covering degumming, deacidification, bleaching, and deodorization—and features a PLC intelligent control system for real-time monitoring and automatic adjustment of critical parameters such as temperature, pressure, and flow rate.

3. Analysis of Core Groundnut Oil Extraction Processes

Before discussing equipment pricing, it is helpful to understand the basic processes of groundnut oil extraction; this will assist you in making an informed choice based on your specific needs.

1) Pre-treatment Section

Pre-treatment involves steps such as cleaning and impurity removal, shelling and separation, crushing and flaking, and steaming/roasting. The steaming/roasting cooker is a critical piece of equipment that determines oil yield and aroma; producing aromatic groundnut oil requires high-temperature roasting (108–135°C) to denature proteins and enhance oil fluidity.

2) Pressing Section

Screw oil presses are the mainstream choice today; they utilize a rotating screw shaft within a pressing chamber to generate high pressure and force out the oil. Achieving oil yields of 40%–45%, they are suitable for large-scale production. Hydraulic oil presses are typically used for cold-pressing processes; they maximize the retention of natural nutrients and flavor, making them ideal for producing premium cold-pressed peanut oil.

3) Solvent Extraction Section (Large-Scale Plants)

Large-scale groundnut oil processing enterprises typically employ solvent extraction methods to recover the residual 5%–8% of oil remaining in the pressed cake. The solvent extractor utilizes the principle of "like dissolves like," employing food-grade solvents to extract residual oil, achieving an oil yield of over 98%.

4) Refining Section

Crude oil contains phospholipids, pigments, free fatty acids, and odor-causing substances; it must undergo processes such as degumming, deacidification, decolorization, and deodorization to become a finished product meeting national standards. Groundnut oil refining equipment capacities range widely—from 1 to 500 tons per day—catering to the needs of oil plants of various scales.

4. How to Obtain an Accurate Equipment Quote?
