New technology cottonseed oil solvent extraction

ABOUT QI'E:

We can provide many kinds of seeds oil production line and crude oil refinery machine, like palm oil refinery machine, crystal machine, dewaxing machine; If you are interest in this kind of products, please feel free to contact me.

ABOUT SUNFLOWER OIL PROCESSING:

At present, sunflower oil production process have two kinds of processing methods: 

pressing and solvent extraction. 

Pressing method is done by physical pressure and extract oil directly from the oil seeds. The 

whole process does not involve any chemical additives, to ensure product safety, health, pollution-free. 

The expeller method is divided into cold pressing and hot pressing. The difference of cold 

pressing and hot pressing is whether use high-temperature process or not. 

Hot pressing using a high temperature, can improve the oil yield, but destroy nutrients; cold-pressed not to use high temperature, the oil is low, but the complete nutritional ingredients.

RAPESEED PRESSING:

The rapeseed have two ways of pressing, cold press and hot press. To improve the oil yield and 

oil quality, generally the hot press is used.

(1) Cold press: Rapeseed/vegetable seeds---Screening---Squeezing---Steaming----Pressing

First, Screening the rapeseed and check the moisture content of rapeseed, if the rapeseed is too 

dry, we need to add 2.5-3% water, later put the seeds into the expeller.

(2) Hot press: Rapeseed/vegetable seeds---Screening---Squeezing---Steaming----Pressing, 

Filter the rapeseed and remove the residue, and then enter the flaking machine for seeds flaking. 

After flaking, will go into the cooker for steaming and roasting, during steaming add 2-3% 

water, will start milling after the seeds become brown and the temperature is 110-120°C.

WHAT ARE THE PRESSING MACHINES LIKE?

MAIN PROCESS OF SOLVENT EXTRACTION PROCESS:

ABOUT SOLVENT EXTRACTION SECTION:

1. Extractor: in the extractor, spraying the solvent to the oil material flake and dissolve the oil 

fats. Then get the wet meal also the mixture of oil and solvent.

2. Solvent pump: spraying the solvent to the oil material continuously.

3. DTDC: separating the solvent from the wet meal.

4. Evaporator: separating the solvent from the mixed oil to get the crude oil and recycling 

the solvent.

5. Stripper: evaporating the rest solvent in the oil.

6. Condenser: cooling the solvent from gas to liquid for recycling.
