Industry Guide

Qi'e Grain and Oil Machinery Co., Ltd. provides a systematic guide for enterprises planning to build or upgrade grain and oil processing production lines. Learn how to select combinations of oil pressing equipment, oil extraction equipment and edible oil refining equipment based on raw material types, production capacity goals, product forms and budget constraints.

For enterprises planning to build or upgrade grain and oil processing production lines, selecting the right equipment configuration is critical to ensuring production efficiency, product quality, and investment returns. Qi'e Grain and Oil Machinery Co., Ltd., with decades of experience in the industry and products exported to over 120 countries, offers this professional guide to help you navigate the complex process of equipment selection for pressing, extraction, and refining stages.

1. Key Factors Influencing Equipment Selection

Before configuring your production line, consider these critical factors:

Raw Material Characteristics: Different oilseeds (soybean, palm, sunflower, rapeseed, etc.) require specific processing technologies. For example, high-oil-content seeds may benefit from pre-pressing before extraction.
Production Capacity Requirements: Daily output determines equipment size, automation level, and line layout (small-scale: 1-50 TPD, medium-scale: 50-200 TPD, large-scale: 200+ TPD).
End Product Specifications: Crude oil, refined edible oil, or specialized products (e.g., medical-grade oil) dictate the need for refining equipment and its complexity.
Budget Constraints: Balancing initial investment with long-term operational costs (energy consumption, maintenance, labor) is essential for sustainable profitability.
Regulatory Compliance: Local food safety standards and environmental regulations may influence equipment selection, particularly for refining and waste treatment.

2. Three-Stage Equipment Configuration Guide

2.1 Oil Pressing Stage: Foundation of Oil Extraction

The pressing stage is the first step in oil extraction, suitable for both pre-pressing high-oil-content materials and direct pressing of various oilseeds. Qi'e Grain and Oil Machinery offers a range of pressing equipment to match different needs:

Equipment Type	Suitable Raw Materials	Capacity Range	Key Advantages
Multifunction Oil Press Machine	Peanut, sesame, rapeseed, sunflower seed	0.5-5 TPD	Versatile, compact, ideal for small-scale operations
Automatic Oil Press Machine	Soybean, cottonseed, palm kernel	5-30 TPD	High automation, continuous operation, labor-saving
Cold Press Oil Machine	Flaxseed, walnut, camellia seed	1-20 TPD	Preserves natural nutrients, no chemical treatment

2.2 Solvent Extraction Stage: Maximizing Oil Yield

For medium to large-scale operations or materials with low residual oil after pressing, solvent extraction is employed to achieve higher oil yields (up to 99%). Qi'e Grain and Oil Machinery's extraction equipment ensures efficient and safe oil recovery:

Key Components of Extraction Equipment:

Extractor: Vegetable Oil Solvent Extractor with advanced design for thorough material-solvent contact
Desolventizer-Toaster: Removes solvent from meal, ensuring food safety
Evaporator and Stripper: Recovers solvent from miscella (oil-solvent mixture) for reuse
Condensation System: Efficient solvent recovery to minimize environmental impact

Ideal for: Soybean, rapeseed, cottonseed, and large-scale palm oil processing lines.

2.3 Edible Oil Refining Stage: Ensuring Quality and Safety

Crude oil contains impurities such as phospholipids, free fatty acids, pigments, and odors. Refining equipment transforms crude oil into high-quality edible oil meeting international standards. Qi'e Grain and Oil Machinery provides tailored refining solutions:

Batch Refining Equipment

Suitable for small to medium-scale production (1-50 TPD). Includes degumming, neutralization, bleaching, and deodorization units in a single integrated system.

Continuous Refining Equipment

Designed for large-scale operations (50+ TPD). Features automated process control, consistent product quality, and high production efficiency.

3. Production Line Configuration Examples

"The right configuration balances raw material characteristics, production goals, and budget. Our engineers work closely with clients to design customized solutions that maximize efficiency and return on investment." — Technical Team, Qi'e Grain and Oil Machinery Co., Ltd.

Example 1: Small-Scale Cold Press Production Line (5 TPD)

Raw Material: Sunflower Seeds → Cold Press Oil Machine → Filter Press → Bottling Unit

Example 2: Medium-Scale Soybean Oil Production Line (50 TPD)

Soybean Cleaning → Flaking → Automatic Oil Press → Solvent Extraction → Batch Refining → Storage Tanks

Example 3: Large-Scale Palm Oil Production Line (300 TPD)

Fresh Fruit Bunches Sterilization → Threshing → Digestion → Pressing → Clarification → Continuous Refining Equipment → Fractionation → Packaging
