Applicable Raw Materials: Common vegetable oils, including soybean oil, rapeseed oil, peanut oil, sunflower seed oil, cottonseed oil, palm oil, rice bran oil, and others.

Semi-continuous refining represents the mainstream medium-scale process for edible oil processing. Its core principle lies in a hybrid design—employing batch processing for the initial stages and continuous processing for the subsequent stages—thereby achieving an optimal balance between investment costs, operational efficiency, and finished oil quality. This system is ideally suited for medium-sized oil mills with a daily processing capacity of 20 to 50 tons.

The deodorization stage utilizes a continuous high-temperature vacuum process, capable of reliably removing free fatty acids and odor-causing compounds. This ensures that the finished oil consistently meets regulatory standards for smoke point and acid value, guaranteeing uniform product quality.

The system does not require highly specialized technical personnel; standard operators can be deployed after undergoing only a short period of training, resulting in lower labor costs compared to fully continuous processing lines.

Characterized by a simple structural design and minimal potential points of failure, the system features core components with high interchangeability. This translates into low maintenance costs and minimal downtime, thereby ensuring the continuity and stability of production operations.
