The process of cold pressing rapeseed oil by oil press machine is to extract the oil directly through external pressure without steaming and frying the oil. The step of steaming and frying is reduced, and the damage to oil cells and nutrients is also reduced accordingly, and the quality of the oil produced is relatively better. The professional oil press machinery manufacturer Henan Huatai Oil Machinery will introduce it in detail for you.

The technological process of cold-pressed rapeseed oil by oil pressing machine is as follows:

Firstly, the rapeseeds is cleaned, tempered, and peeled to get rapeseed kernel;

Then, directly pressed to get cold-pressed crude oil;

Next, filtered to get cold-pressed finished rapeseed oil.

However, the residual oil rate is relatively higher in the cold pressing process of the rapeseed oil pressing machinery. In order to solve this problem, it is necessary to solvent extraction to the cold pressed finished rapeseed oil, which can improve the rapeseed oil yield.
