Cottonseed oil is also an increasingly popular edible oil in the oil extraction market today, and it is also one of the most popular edible oils. Especially in some countries in Africa, such as: Malawi, Kenya and so on. So, how does the Malawi 6YL-160 cottonseed oil press to produce cottonseed oil? How to open a cottonseed oil mill? Next, Benteng Machinery will introduce you to the detailed cottonseed oil extraction process, cottonseed oil refining process, as well as cottonseed oil extraction equipment and cottonseed refining equipment.
1. How to press cottonseed oil with cottonseed oil pressing equipment?
(1) Screening and cleaning
The screening device can choose a vibrating screen. The purpose of screening is to remove impurities, dust, etc. in raw materials. It can not only improve the oil yield, but also increase the service life of the machine and avoid excessive wear and tear on the machine caused by impurities in the raw materials.
(2) Fried cottonseeds
Before pressing, steaming and frying the raw materials can reduce the moisture in the raw materials and increase the oil yield efficiency. This is an essential step in the hot pressing process. If you choose cold pressing, this step is not required.
(3) Squeezing
Pressing is usually done using a 6YL-160 cottonseed oil press. Pay attention to the temperature when pressing, avoid too high or too low, resulting in reduced oil yield. The most suitable temperature for pressing cottonseed is 120-130 degrees Celsius.
(4) Filtering
After pressing, stand still the cottonseed oil for a period of time. And then it can be pumped into a plate and frame oil filter for filtration. After filtering, you can get clear cottonseed oil.
2. The refining process and steps of cottonseed oil
(1). Degumming
This step is used for neutralizing washing, acid removal.
(2).Deacidification
The crude oil contained in the process of removing free fatty acids is deacidified by steam distillation and other methods.
(3). Decolorization
That is, bleaching, which removes other colors from crude oil. Get clearer and translucent finished oil.
(4) Deodorization
Eliminates odors from oil at high temperatures and odors from water vapor.
The above is the cottonseed oil extraction process and cottonseed oil refining process, if you need to open a cottonseed oil extraction plant in Malawi and other African regions, and need to buy 6YL-160 cottonseed oil press.
