4. Processing Description of Chinese Manufacture! cottonseed oil processing plant cottonseed oil pressing Machine cottonseed oil mill machine
Cleaning: Windowing system is used to remove the impurity from cottonseed, such stone, irons etc
Dehuilling : As usual, It needs to remove the cottonseed shells, It will be good for futher processing.
Cracking: Breaker roll or a swinging hammer grinder or a combination of both then breaks the kernel into small fragments. This increases the surface area of the kernels, thus facilitating flaking.
Flaking: The kernel fragments are then subjected to flaking in a roller mill. The thickness of the kernel cakes are subsequently reduced as they travel from the top roller to the bottom. This progressive rolling initiates the rupturing of cell walls.
Cooking: Adjust the moisture content of the meal to an optimum level ;Rupture cell walls (initiated by roiling) ;Ensure that the action of the enzymes that increases the free fatty acids (FFA) of the oil is stopped i.e. Reduces viscosity of the oil; Coagulate the protein in the meal to to facilitate the separation of oil from protein materials.
Screw Press: The properly cooked meal is then fed to the screw press, which consists of an interrupted helical thread (worm) which revolves within a stationary perforated cylinder called the cage or barrel. The meal is forced through the barred by the action of the revolving worms
