Use of Ultrasound in Rape Oil Extraction Process

An extraction method for the production of vegetable oils is essential in the food industry. Getting oil in this way is the most economical, provides maximum degreasing of oilseeds, and allows you to achieve high quality of the product. The main advantage of the extraction method of obtaining vegetable oils in comparison with the press is the significant increase in the yield of oil, even in the processing of low-oil seeds.

Introduction All extraction processes are limited by diffusion at the interface of the phases through a diffusion layer with gradient concentration of the extraction of matter. Traditional extraction methods are long-lasting. Ultrasound can significantly accelerate the extraction process, increase output, reduce the cost of extraction of matter and improve the quality of the product. The influence of ultrasonic oscillations with 22 kHz frequency, low resonance cavitation (17-100 Hz) and vibration turbulent devices on the output, composition of extraction products was investigated and analyzed. It has been shown that in all cases the yield of the extract increases, but the quantitative characteristics of the product obtained are different. The process of epoxidation of obtained extracts and their application in the process of modification of road bitumen was investigated. Taking into acount the considerable time of the modification process, and some differences in the results obtained in studies using oils obtained by different extraction methods, a decision was made on the need to intensify the processes of modification of road bitumen by use of ultrasound [1]. Different methods of extraction, their advantages and disadvantages were considered. Some conclusions are made about the use of ultrasound in the extraction process for the production of oils, and in the process of modifying of road bitumen with epoxy compounds.
