Cotton Seed Pressing

We can provide turnkey plant for you:

Cotton seed pressing and solvent extraction plant with capacity ranging from 30 t/d to 2,000 t/d

We provide tailored designs of cotton seed dehulling process are delivered to meet your requirement for protein content in extraction meal. The seed kernel is flaked after conditioning, and extrusion or pressing followed by extraction are both available.


There are two kinds of processes. The first one is: Dehulling, Kernel and Hull Separation, Flaking, Cooking, Pressing, Oil Residue Separation. The second one is: Dehulling, Kernel and Hull Separation, Softening, Flaking, Cooking, Expanding, Cooling.

  • Cotton seed oil production line
  • Cotton Seed Pressing
  • Kernel and Hull Separation Section


1. Dehulling Section
Frequently-used equipment tooth type dehuller is designed to crack cottonseed hull and separate kernel through double rolls with speed difference.
2. Kernel and Hull Separation Section
Screening and aspirating are combined to separate hull and kernel from dehuller. Frequently-used equipment are classifying screener, round screener, separating screener.
3. Softening Section
Horizontal drum rotary cooker is designed to adjust temperature and moisture of cottonseeds kernel previous to flaking, improving oil yield greatly.
4. Flaking Section
The purpose of flaking is to flake the broken cottonseeds into thin flakes (from 0.3 to 0.35mm) for the subsequent oil extraction through mechanical pressing. In addition, flakes thickness can be adjusted through the roll pressure adjustment device.
5. Pressing Section
Cottonseed is a kind of high oil-containing oilseed. Generally, it is necessary to extract a portion of oil by mechanical pressing prior to the subsequent process. Expeller with auxiliary cooker ensures material reach proper temperature and moisture. Pressing cakes containing residual oil from 14% to 18% is then treated by solvent extraction while crude oil is to be filtered.
The temperature of the soybean after expanding is above 100℃, the moisture is over 12%. Due to of the evaporable feature of solvent, we need to cool the materials before extraction.
6. Expanding Section
The purpose of hull crushing is to change the physical features of the hull, make it easier in the downstream processing such as pelleting. The shape of the hull is supposed to be the same as the meal, so that we can add the hull into the meal for the purpose of adjusting the proportion of protein.
7. Oil Residue Separation Section
Due to the high content of residue in crude oil, it is necessary to separate oil residue by oil drag conveyor firstly, crude oil then enters to settling tank for further separation. The collected residue is returned to the pressing section while crude oil from settling tank is pumped to frame filter or leaf filter for further removing impurities.
8. Expanded Material/Pressed Cakes Cooling Section

Cooling drag conveyor is designed to cool down expanded material/ pressed cakes with high efficiency, then cakes is conveyed to the extraction plant.
