Oilseed Expander Machine, Soybean Extruder

Oilseed extruder is also called expander or extruding machine. This oil extruder machine is suitable for rice bran, soybean and other low oil content oilseeds and pre-pressed cake to be expanded. Oilseed Expanders are particularly helpful in soybean oil plants where they permitted considerable increase in plant capacity. Except soya, oilseed expander is also suitable to process other oilseed materials, including prepressed oilseed cakes where.

Enhancing Oilseed Processing Efficiency:

Oilseed expanders have proven to be instrumental in increasing the efficiency and capacity of oilseed processing plants. Traditionally, oil extraction from low oil content oilseeds and pre-pressed cakes posed challenges due to their compact structure and resistance to conventional extraction methods. However, with the introduction of oilseed expanding extruders, these limitations have been overcome.

The expanding process involves subjecting the oilseed material to heat, pressure, and mechanical forces within the extruder. This combination of factors causes the oilseed to undergo structural changes, resulting in the expansion of the material. The expanded oilseed possesses increased porosity and improved accessibility, facilitating greater oil extraction during subsequent processes.

Benefits in Soybean Oil Plants:

Soybean oil plants, in particular, have witnessed substantial advantages through the utilization of oilseed expanders. Soybeans are known to contain a relatively low oil content, making extraction challenging. By employing an oilseed expanding extruder, soybean oil plants have experienced a considerable increase in their processing capacity.

The expansion process breaks down the cellular structure of the soybean, leading to improved oil extraction rates. The increased porosity of the expanded soybean allows for greater contact between the oil-bearing cells and the extraction solvent. Consequently, more oil can be extracted efficiently, maximizing the yield and profitability of soybean oil production.

Versatility for Various Oilseed Materials:

Beyond soybeans, oilseed expanders exhibit versatility in processing a wide range of oilseed materials. They are capable of handling different oilseeds and pre-pressed oilseed cakes, presenting a valuable solution for oilseed processing facilities.

Oilseeds with inherently low oil content can benefit from the expansion process, as it enhances the oil extraction efficiency. Furthermore, pre-pressed oilseed cakes, which are remnants from previous extraction processes, can undergo expansion to unlock additional oil content. This allows for further optimization of oil extraction and reduces waste, making oilseed expanding extruders an environmentally friendly choice.

The principle of the oilseeds extruder machine:

The expander is made of a cylindrical barrel inside of which is a worm shaft with interrupted flighting. Protruding from the barrel wall are a number of stator pins which intermesh with the interruptions of the flighting and allow for high turbulent, kneading and shearing action on the oilseed flakes as it propelled through the barrel. When the oilseed is discharged from the extruder, the condition of the oilseed is changed from high temperature and pressure to atmospheric pressure and temperature in a moment, resulting in the rapid release of water from the material structure. Then the oilseed is expanded and formed, so as to obtain loose and high strength extruded materials.
