The
main equipment of mustard oil refinery plant is various kinds of vessels and tanks carrying on different tasks
with additives. These tanks may include sedimentation/filtering, neutralization
(removing free fatty acid), degumming, decolorization (bleaching),
deodorization, especially the dewax process is necessary, more wax would
destroy the quality of cooking oil. Different combination of steps and the treating degree of each step result in
different grade cooking oil and salad oil.

Degumming:
This
is the most important section of hydrate de-gumming, manage the adding water
(there is a little P-acid in the water) amount, temperature and add water
speed, usually water adding amount is about 3 times of phospholipid content,
that is 3-10% oil weight, water temp needs to be higher than oil temp.
Deacidification:
This
part adopt alkali refining method, that is use alkalis like (NaOH) to neutral
the free fatty acid in oil, during this process it will produce soap stock ,
then separated from the oil by setting several hours. NAOH solution, not only
neutral free fatty acid, also can act with other matters like protein, mucus,
phospholipid, pigment. After settling, release the soap stock from the tank
bottom. Adding hot water to rinse, remove off the leftover lye, soap and some
unhydrated phospholipid in the oil. Finally pumping soap stock out from the
tank bottom.
Decolorization:
In
normal situation , there is pigment in the crude oil , we need to using the
active clay to absorb the pigment away , after 20 mins , we use the vibrating
filter to filter the waste clay away . If you want to get light color oil , you
need to add more active clay . That is mean , the customer can accord to his
requirement to control the oil color. This process is carried out under the mustard
oil mill and mustard oil expeller machine condition.
Deodorization:
In mustard oil mill plant, usually use stripping deodorization tower. The peculiar smell
impurity and oil have different volatility. Under the condition of high
temperature, let the peculiar smell impurity stripping with steam to
deodorization.
