Technical Field

[0001] The utility model relates to the field of rapeseed oil production, in particular to a device for improving the oil yield of low-temperature cold-pressed rapeseed oil. Background Art

[0002] Cold pressing, or low-temperature pressing, means that the oil is squeezed out of the raw material directly with the help of mechanical force without being steamed or fried. Compared with traditional processes, it can minimize the damage to nutrients and can obtain high-quality oil and cakes at the same time. It is a "green and environmentally friendly" oil-making process. Low-temperature pressed oil refers to edible vegetable oil obtained by pure physical pressing without heat treatment and only using physical means to remove impurities. Low-temperature pressing omits the rolling and steaming steps in traditional processes, and significantly reduces the energy consumption of rapeseed processing. The existing oil pressing process usually uses an oil press to press rapeseed.
