Oil extruder machine is key pretreatment equipment in complete oil mill plants, widely used in extraction production lines for oilseeds such as soybeans, rapeseed, cottonseed, and rice bran. Through intense extrusion, frictional heat generation, and steam injection, the cellular structure of the oilseed is thoroughly disrupted, forming expanded pellets. This process significantly improves solvent permeability into the oilseed, increases the extraction rate, shortens extraction time, boosts the oil output of the extractor, while also reducing the solvent content in the wet meal and the energy consumption for desolventizing.
Working Principle of Oil Extruder Machine
After oilseed flakes are uniformly fed into the extruder:
1. During advancement within the barrel, they are subjected to intense extrusion , continuously increasing material density
2. Simultaneously subjected to the combined effects of friction heat generation and steam injection
3. The material is thoroughly mixed, heated, and pressurized
4. Finally subjected to strong expansion action, forming loosely structured expanded pellets
Core Features and Advantages
– Thoroughly Destroys Cell Structure: Extrusion expansion completely disrupts the oilseed cell structure, fully exposing the oil
– Improves Solvent Permeability: Expanded pellets are porous and loose, allowing faster and more uniform solvent penetration
– Increases Extraction Rate: Extraction time is shortened, significantly improving production efficiency
– Boosts Extractor Oil Output: Processes more oilseeds in the same amount of time
– Reduces Solvent Content in Wet Meal: Residual solvent in wet meal decreases, reducing the burden on subsequent desolventizing
– Energy Saving and Consumption Reduction: Energy consumption of wet meal desolventizing equipment is greatly reduced
– Wide Applicability: Suitable for various oilseeds including soybeans, rapeseed, cottonseed, rice bran
– Continuous Production: Capable of stable continuous operation, adapting to industrial large-scale production

Frequently Asked Questions (FAQ)
Q: In which process step is the oil extruder mainly used?
A: It is mainly used in the pretreatment stage of oilseed extraction production lines, performing expansion treatment on oilseeds before they enter the extractor.
Q: What are the benefits of expansion for extraction?
A: Expansion destroys the oilseed cell structure, creating a porous structure that significantly improves solvent permeability, increases the extraction rate, shortens extraction time, and boosts oil production.
Q: Which oilseeds is it suitable for?
A: It can be used for common oilseeds such as soybeans, rapeseed, cottonseed, and rice bran.
Q: Can it reduce energy consumption?
A: Yes. After expansion, the solvent content in the wet meal is reduced, which significantly decreases the energy consumption of the subsequent wet meal desolventizing equipment.
