Description

Technical Field

[0001] The utility model relates to the field of oil press equipment, in particular to an oil press for rapeseed oil. Background Art

[0002] Rapeseed oil is what we commonly call rapeseed oil, also known as rapeseed oil, coriander oil, canola oil, sesame oil, and canola oil. It is an edible oil squeezed from rapeseed. It is one of the main edible oils in my country. It is mainly produced in the Yangtze River Basin and Southwest and Northwest areas. Its output ranks first in the world. Rapeseed oil is golden or brown in color and has a certain irritating smell, which is called "green smell" by the people. This smell is caused by a certain amount of mustard glycosides in it, but the superior varieties of rapeseed do not contain this substance.

[0003] The oil press is a device of oil processing machinery. It is a machine that squeezes the pre-treated oil billets to extract vegetable oil. The screw oil press used as a pre-pressing machine pre-presses the oil at a relatively high pressure, and then puts the pre-pressed billet into the oil press for further pressing or extracting the oil by leaching. Therefore, the volume of the pressing chamber at the inlet and outlet ends varies greatly, and the production capacity is also large. The oil press can operate continuously with low labor intensity. The residue cake after oil extraction is thin and small, which is convenient for comprehensive utilization.

[0004] At present, rapeseed is generally extracted by an oil press. During the process of extracting rapeseed oil by the existing oil press, a certain amount of rapeseed residue will be contained in the extracted rapeseed oil. However, the existing oil press has a low residue removal effect, so that the rapeseed residue in the rapeseed oil cannot be filtered out, resulting in a decrease in the edible taste of the rapeseed oil.

[0005] Therefore, it is necessary to provide a new oil press for rapeseed oil to solve the problems of the technologies described above. Utility Model Content
