Ultrasonic Mixing for Biodiesel Production 20khz ultrasonic Rapid extraction technology
Ultrasonic field enhanced oil extraction can significantly improve the extraction efficiency, improve oil quality, save raw materials and increase oil extraction. Bi Hongwei compared the extraction of γ 2 linolenic acid by homogenate method and ultrasonic method. The results showed that the amount of oil obtained by ultrasonic method was more than that by homogenate method, which increased by 12.8% and saved manpower. The yield of peanut oil increased by 2.76 times when peanut oil was extracted. Gorodendrd et al. Used ultrasonic extraction technology to extract oil from sunflower seeds, which increased the yield by 27% - 28%. When the amount of cottonseed oil is the same, the amount of cottonseed oil extracted in one hour is 8.3 times higher than that without ultrasonic treatment if the strength is 1.39w/cm2. At present, the main extraction method of cod liver oil is dissolution. The oil yield is low, and the high temperature destroys the vitamin. Ultrasound can also be used for the processing and extraction of animal oil, such as cod liver oil. Soviet scholars used 300, 600, 800, 1500 kHz ultrasonic wave to extract cod liver oil respectively. In 2-5 minutes, almost all the oil in the tissue could be extracted. The vitamin contained in the oil was not damaged, and the quality of the oil was better than the traditional method.
Ultrasonic field can not only enhance the extraction process of substances by conventional fluid, but also enhance the extraction process of substances in supercritical state. Chen Jun et al. Studied the extraction process of wheat germ oil by supercritical CO2 fluid enhanced by ultrasound. The extraction rate of wheat germ oil increased about 10% after supercritical fluid extraction with ultrasonic field, and the degradation of wheat germ oil was not caused. Ultrasonic extraction is very active in the research and application of oil extraction. The experiments and applications that have been carried out involve the extraction of octagonal oil, almond oil, clove oil, perilla oil, evening primrose oil, etc.
