Description

Technical Field

[0001] The utility model relates to the technical field of rapeseed oil production, in particular to a rapeseed oil degreasing device used for rapeseed oil production. Background Art

[0002] Rapeseed is the fruit of the cruciferous crop rapeseed. It has long siliques, many pods and full grains. The oil mud content varies slightly depending on the type of rapeseed. As a herbaceous cruciferous crop, it is one of China's major oil crops and nectar crops. Its seeds are one of the main varieties of raw materials for making soaked oil mud. It is cultivated throughout China and is divided into winter rapeseed and spring rapeseed. Its planting area accounts for more than 40% of China's total oil crop area, and its output accounts for more than 30% of China's total oil output, ranking first in the world.

[0003] At present, a variety of different methods have been developed for rapeseed oil degreasing, including high temperature degreasing, frozen degreasing, centrifugal degreasing and other technologies. Among these methods, centrifugal degreasing has attracted widespread attention in the industry due to its unique advantages. Centrifugal degreasing mainly involves high-speed centrifugation of frozen rapeseed oil to effectively remove impurities and reduce acid value, ultimately obtaining rapeseed oil with more stable quality and higher purity.

[0004] However, although centrifugal degreasing technology has significant advantages, it also has some problems that cannot be ignored. After centrifugal degreasing, a certain amount of sludge often adheres to the inner wall of the oil barrel, which is produced during the degreasing process. At present, most companies use manual scraping to clean up the sludge, which is not only cumbersome and inefficient, but also difficult to thoroughly clean the inner wall of the oil barrel. In the long run, these residual sludge may have an adverse effect on the subsequent rapeseed oil degreasing, and even affect the quality and safety of the product. Utility Model Content
