Mini Soybean Oil Mill Setup Guide for Efficient Extraction

Mini Soybean Oil Mill Plant Setup Guide

Overall Design And Process Planning For Mini Soybean Oil Mill

Starting a mini soybean oil mill plant begins with a well-structured plant design and process flow that ensures high extraction efficiency and minimal losses. The business planning stage involves mapping raw material intake, oil extraction, refining steps, and output logistics. Typically, a 1-5 ton/day plant requires a raw soybean hopper of 2-3 tons capacity, while a 50-70 kW power supply is sufficient for a fully automated line.

Raw Material Handling And Pre-Treatment

Soybean preparation is critical. Raw beans usually contain 8-12% moisture, which must be reduced to 6-7% for optimal pressing efficiency. Pre-treatment steps include:

• Cleaning: Removing stones, dust, and foreign matter using vibrating screens.
• Dehulling: Separating hulls to increase oil yield by up to 2%.
• Conditioning: Steam-heating the beans to 80-90°C for softening.

Extraction And Refining Layout

The extraction section is the heart of the mini mill. A typical line integrates:

• Cold or hot oil pressing units capable of producing 150-500 kg/hour per unit.
• Filtration tanks for sediment removal.
• Refining vessels with degumming and neutralization capabilities.

Core Soybean Oil Mill Equipment Selection And System Configuration

Selecting the right machinery directly impacts oil recovery and operational stability. Mini oil pressing machines are the centerpiece, ranging from 500 kg/h to 1 ton/h capacity. Secondary equipment includes:

• Filtration units: Plate or centrifugal filters, removing 95-98% impurities.
• Refining tanks: Degumming, neutralization, and bleaching with 100-200 L capacity.
• Energy-Efficient Motors: 5-15 kW for small units.

Equipment Selection Principles:

• Match press capacity with refining tank volume.
• Ensure modular piping for future upgrades.
• Prioritize equipment with low maintenance (<30 min daily cleaning).

Soybean Oil Extraction Factory Layout And Production Line Optimization

Efficient layout improves both safety and throughput. Typical plant dimensions for a mini mill are 200-350 m², with separate zones for storage, processing, and refining. Key layout strategies:

• Unidirectional Workflow: Raw materials → pressing → refining → storage.
• Safety Standards: ≥1.2 m aisle width and proper ventilation.
• Modular Expansion: Space allocation for additional presses and tanks.

Additional Tips:

• Material Handling: Use conveyor belts with 0.5-1 t/h capacity to reduce manual labor.
• Energy Saving: Combine heat recovery with pre-heating conditioners.
• Ensure compliance with local industrial safety regulations.
