How much oil can be extracted from 1 kg of sunflower seeds?

The amount of oil that can be extracted from 1kg of sunflower seeds depends on the type of sunflower seed and the extraction process. It is about 290g-490g. Different types of sunflower seeds have different oil yields. Different oil extraction processes have different oil yields. Henan Glory, a professional sunflower seeds oil extraction machines manufacturer, will introduce in detail below.

1. Types of sunflower seeds

There are two main types of sunflower seeds, oil sunflower seeds and edible sunflower seeds. The oil content of sunflower seeds is about 45%-54% (calculated as 50%), and the oil content of edible sunflower seeds is about 22%-35% (calculated as 30%). Among them, oil sunflower seeds are usually the main raw material to extract sunflower oil.

2. Sunflower oil extraction process

- Physical pressing process

The physical pressing process generally refers to direct pressing with oil press machines. The residual oil rate of this process is almost 6%. Through this process, the oil yield rate of oil sunflower seeds is about 44%, that is, 1 kilogram of oil sunflower seeds can be extracted from 440g sunflower oil. The oil yield rate of edible sunflower seeds is about 24%, that is, 1 kilogram of edible sunflower seeds can extract 240g of sunflower oil.

- Chemical solvent extraction process

The chemical solvent extraction utilizes the mutual solubility of oil and n-hexan organic solvent to extract and dissolve the sunflower oil with a residual oil rate of less than 1%. Through this process, the oil yield rate of oil sunflower seeds is about 49%, that is, 1 kilogram of oil sunflower seeds can extract 490g of sunflower seed oil. The oil yield rate of edible sunflower seeds is about 29%, that is, 1 kilogram of edible sunflower seeds can extract 290g of sunflower oil.
