zhengzhou maosheng grain and oil  machinery Co., Ltd. was founded in 1976, after nearly 40 years of development and growth, has become a well-known Chinese grain and oil machinery manufacturing enterprises with import and export rights, in 2002 passed the ISO9001 quality management system certification, National Food Processing Equipment Engineering Technology Research Center, the National agro-processing technology and equipment research and development sub-centers and the provincial post-doctoral research base development platform.

1.Pretreatment process 
Oil seeds→cleaning→stones removal→magnetic selection→cracking→softening→flaking→cooking→to oil press/extraction workshop.

2.Extraction process 
Oil cake→extraction with solvent→mixed oil→evaporation→evaporation→steam-stripping→crude oil 

3.Refining process
Crude oil→degumming, washing, drying →decolorization →deacidification →deodorization →refined oil

4. Specificaitons 

 (1).Cleaning:Remove the raw material peanut in various impurities, such as: iron, stones, clump, such as the plant leaf, clean up after the raw material peanut impurity content should not exceed 0.2%.

(2).Crushing:Oil seed is crushed into 6-8 pieces. In order to meet the requirements of crushing, the peanut is suitable for crushing with the moisture of 7% to 12%.

(3). Softening: The purpose of softening is to adjust the moisture and temperature of oil, and make it soft.

(4).Flaking process: Rolling raw material into flakes, and the purpose is to increae surface area, destroy the peanut cell tissue, shorten the way of oil out from cake.

(5).Drying:Adjust moisture of rice bran to meet the requirement of going to extraction process. 

(6).Cooking process: use steam cooking, inject direct steam and cook the flakes to meet the requirement of oil press.

(7). Pre-press: Press the flakes to leave about 16%-18% in the cake. The cake will go to extraction process.

(8).Filteration: using vibration filter to filter the crude oil to remove the impurities.
