2.Pretreatment process of castor oil extraction line:

a. Cleaning device:  To remove various impurities in oilseeds, such as: iron, stones, clump, such as

the plant leaf, clean up till impurity content does not exceed 0.2%.

b. Crushing machine:  Oilseeds are 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%.

c. Softening Process:  The purpose of softening is to adjust the moisture and temperature of

oil, and make it soft.

d. Flaking process:  Rolling raw material into flakes, and the purpose is to increase surface 

area, destroy the peanut cell tissue, shorten the way of oil out from cake.

e: Cooking process:  Use steam cooking, inject direct steam and cook the flakes to meet the

requirement of oil press.

f. Pre-press:  Press the flakes to leave about 16%-18% in the cake. The cake will go to 

extraction process.

g. Second oil press: Press the cake till the oil residue is about 5%.

FAQ                                                                                           

Q1. Does the maize mill line can produce different kinds of maize meal,maize flour

same time?
A1, Yes,the maize mill line can produce different size maize meal or maize flour at same

time at one production line. 
Q2. Does the maize mill line can running with Generator? 
A2, Yes,the maize mill line can running with Generator
Q3. Does the maize meal packing machine can pack different bags?
A3, Yes,the packing machine can pack 1kg-5kg;5kg-20kg,12.5kg-25kg,50kg etc.
Q4. Does the maize mill line can process maize and wheat same time? 
A4, No,because the maize and wheat Physical Characteristics is different,such as the

shape,the hardness,all are different,and the final product flour size is also different. The

cleaner,the roller mill parameter,the plan sifter sieve all are different.

Q5. What is your advantage for the maize meal milling machine

A5, All Milling Line can be designed into PLC Controlling System and also can be

designed according to customers’ requirement.

Q6. Why buying the Maize production line from our factory?

A6, Firstly, Clients’ good feedback, maybe they buy the small capacities and middle

capacities, normally after 2 years buy the bigger capacities.Second,Overseas service

center available, 24 Hour after-sales service. Third,Warranty 1 year. Fourth, Chinese

professional engineer guide installation and commissioning.
