LD mustard seed oil mill, new product nut & seed oil expeller oil press, oil seed production line
What oilseeds are available?
Main process of pressing section:
Main machines in pressing section:
A. Magnetic cleaning: To remove the metal impurities.
B. Cleaning sieves: To remove some mud, leaves and other pellets.
C. Shelling: To break the shells of the oil seeds .
D. Kernel & shells separating sieve: To separate shells from the kernels.
E. Flaking: To flake the kernel into flakiness. After flaking, the materials is much easier to getting oil.
F. Cooking: Combines wetting, heating, cooking and drying functions together, the
effectiveness of the cooking will affect the oil out rate and the quality of the meal.
G. Pressing: The most important part in the press production line. The internal structures of
the press machine can affect the oil rate.
H. Filter: After getting the crude oil, there is some oil residual mixed with crude oil, you need
to filter it to get cleaning oil .
What are the pressing machines like?
Brief introduction of large scale pressing machine:
Large scale pressing machine is able to process vegetable raw materials over 15 tons per day, and it is mainly being used in the middle and large scale oil extracting mills. All of the big capacity oil expeller presses are with high oil output and low oil residual, the oil made is of good quality, pure and rich nutrient.
LD large scale capacity oil press machines are suitable for extracting various vegetable oil seeds and nuts for edible purpose or for biodiesel processing. For example, they can process soybeans, canola/ rapeseed, coconut/ copra, groundnuts, sunflower seeds, castor bean, maize germ, rice bran, tea seed, safflower seed and so on.
LD generally put these big oil press machines into two categories: one is pre-press oil expeller including steam cooker to be used for heating and adjust the water content of the raw materials before expelling, the other is low temperature oil expeller for cold pressing, which can protect the nutrition element in the oil.
Pre-press Oil Expeller
The big scale pre-press expellers are continuous screw type oil pressing machines, which is applicable for the pre-pressing and solvent extraction or twice pressing process. They are always being used to press oil-bearing crops such as peanut kernel,cottonseed kernel, rapeseed and sunflower seed kernel, etc.

Oil refining means separating impurity from oil based on the different characteristics of oil and impurity, in order to enhance the stability and security of oil. Oil refining including two technologies, physical refining and chemical refining.echnological process details of LD mustard seed oil mill, new product nut & seed oil expeller oil press, oil seed production line:
AAA1
1. Acid reaction process
Oil temperature can be adjusted by screw plate heat exchanger. When the temperature is heated to about 80℃, mixing about 85% food grade phosphoric acid into acid reaction tank for reacting. In the tank, most non-hydrated phospholipid transfer into hydrated phospholipid.
AAA1
2. Neutralization process
In the neutral section, degummed oil with appropriate temperature and the appropriate concentration of alkali liquor, into the neutralization centrifugal mixer mixing, in order to achieve the effect of mixed, the mixture is then sent to neutralization tank for enough time, in this process, excessive alkali neutralization of free fatty acids and some phosphate form soapstock , after pumping oil soap mixture into heater oil heating to 85 ~ 90 ℃ in centrifuge separation oil - soap (or oil - glue). Oil soapstock of the separated (or foot) feet into the oil tank, and then to the salting out with soap pump tank isolated part of the oil.
AAA2
3. Washing process
Neutral oil from separator, still contains about 500 ppm soap, in order to reduce the residual content of soap, oil is joined by about 10% of hot water, washed in the washing mixer, hot water will absorb oil soap and other impurities, then in the water separator are separated.
