The mustard oil pretreatment & pressing machine is a series of processing before oil extraction, like cleaning,crushing,softening, flaking,drying and pressing . The purpose is to remove the impurities and make it into a certain structural material to meet the different requirements of oil. According to the different varieties of oil and its production process,the choice of pre-treatment process and methods are also different.

The pre-pressing is a process of high oil content oilseed. It’s suitable for peanut, rapeseed, cottonseed, sunflower seed, rice bran, safflower seed, castor oil, sesame seed, corn germ, rapeseed oil and so on.
After pre-pressing, most crude oil pressed out, while there is some percentages still inside the raw material. To get all oil pressed out, we need to take solvent extracting method. There are many advantages in solvent extraction:
a). high oil pressing rate, oil residual is no more than 1% in cake,
b). convenient for big capacity production,
c). high automatic control,
d). closed production condition, low temperature press, clean working condition
e). easy access to solvent.

Mustard oil solvent extraction machine main process:
(1) The pressed cake (form prepressed workshop) send to cooking vegetable edible oil extraction machinery by the scraper conveyor. Mixed oil will extracted from the pressed cooking vegetable edible oil cake by the solvent. After this step, we will get cooking meal and mixed oil.
(2) Cooking vegetable edible oil meal will sent to the toaster. Through the toaster, the solvent will separate from the meal. The solvent goes to condenser and is reused to cooking vegetable edible oil extraction machinery.
(3) Mix oil from the cooking vegetable edible oil machinery enters into 1st evaporator and 2nd evaporator, most of the solvent in the mix oil is separated.
(4) The mix oil from 2nd evaporator goes to stripping tower and almost all the solvent is separated. From the stripping tower, we can get crude oil and solvent. The solvent is sent to condenser and is reused to cooking vegetable edible oil extraction machinery.

The vegetable oil obtained by musterd oil pretreatment and pressing machine or mustard oil solvent extraction machine,which contains water, mechanical impurities, fat-soluble impurities, peptizing impurities, trace impurities, etc. ,failed to meet the edible standards.
Refining refers to remove the impurities in crude oil, to get a good quality of the first class of edible oil.
Types of mustard oil refining machine:
1.Batch type mustard oil refining machine,suitable for small capacity like 1-2-3-5-10TPD
2.Semi-continuous mustard oil refining machine,suitable for medium capacity like 10-50TPD
3.Full continuous mustard oil refining machine,suitable for large capacity above 30TPD
Main process of mustard oil refining machine:
1. Degumming. In this step gums in crude oil are removed by hydration with the help of phosphoric acid.
2. Neutralization. In this step free fatty acids are neutralized by using sodium hydroxide and convert them into soap. Additional impurities are also removed by adsorption on soap.
3. Bleaching. During bleaching, unwanted pigments are adsorbed physically and oil will become much clearer.
4. Deodorization. Deodorization is used to remove unacceptable odors by steam distillation, the odoriferous compound are stripped off with the help of live injected steam into heated oil under high vacuum pressure.
