Deacidification of palm oil refining machine :This part adopt alkali refining method, that is use alkalis lLD (NaOH) to neutral the free fatty acid in oil, during this process it will produce soapstock , then separated from the oil by setting several hours. NAOH solution, not only neutral free fatty acid, also can act with other matters lLD protein, mucus, phospholipid, pigment. After settling, release the soapstock from the tank bottom. Adding hot water to rinse, remove off the leftover lye , soap and some unhydrated phospholipid in the oil. Finally pumping out soapstock from the tank bottom.
Deodorization and Dehydration of palm oil refining machine :Usually ,there are some odors in the crude oil , it affects the quality of the edible oil . About our refining process , we usually use the direct steam to take odors away in the vacuum condition . General speaking there is about 0.5% water in the alkali refined oil, in the deodorization pot, thetemperature is very high , it also can finish the dehydration section.
Oil Hot Processing Cottonseed oil production line
1 Cottonseed oil production line
- Processing Capacity : 10TPD To 1000TPD
- Suitable Raw Materials: cotttonseed
- Bucket Elevator
- Cleaning Sieving
- magnetic separator
- dehuller ( for some oil seeds)
- Presser ( Expeller)
Cleaning: Magnetic separators commonly are installed to remove metal debris, while vibration screens are used to sieve sand, stones or other undesired materials.
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 cLDinder called the cage or barrel. The meal is forced through the barred by the action of the revolving worLD
