Ultrasonic circulation extraction technology also has many advantages in oil deep processing, which can replace traditional processing methods in various oil processing, reduce processing costs and improve product quality.
　　 l , application of ultrasonic circulation extraction in vegetable oil extraction
Using ultrasonic extraction, ultrasonic cavitation can produce micro-acoustic flow, which can effectively break the boundary layer, greatly accelerate the diffusion speed, and effectively increase the proposed speed by 2-10 times. The method has the advantages of simple method, high oil yield, pure oil taste, clear color, short production cycle, no heating, no damage to active ingredients, and comprehensive extraction of other useful ingredients, which significantly improves economic benefits.
　　 2 , the application of ultrasonic circulation extraction in the extraction of aromatic oil
Most of the extraction of aromatic oils is carried out by steam distillation. During the extraction process, aromatic oils are prone to oxidation, polymerization, pyrolysis, etc., resulting in loss of aroma and low rate of fragrance. Ultrasonic enhanced extraction can significantly improve the extraction rate of aromatic oil. Make the aroma more mellow and longer lasting.
　　 3. Application of ultrasonic circulation extraction technology in animal oil processing
The oil obtained by the method of smelting animal fat to extract animal oil is easy to coke and has a low oil yield. Using ultrasonic extraction method in a very short period of time (2 to 10 minutes) to make animal fats freed, and the grease contained within the vitamin is not destroyed, grease clear.
Third, the application of technology in the sugar added deep cycle T of the ultrasonic extraction
Extracting sugar from sugar beet, using ultrasonic extraction method can shorten the extraction time by half, the yield is increased by 12-14 %, and the sugar extraction speed can be increased by 78 %.
Fourth, the application of ultrasonic circulation extraction technology in the deep processing of fruits and vegetables
Ultrasonic wave is beneficial to further refinement of the pulp, degrading the pectin in the juice, reducing the viscosity of the juice, thereby increasing the yield, quality and filtration speed of the juice, and at the same time, significantly reducing the plant cells after being ultrasonically treated. The digestion and absorption rate of nutrients by humans and animals.
Fifth, the application of technology in the tea deep plus T in the ultrasonic extraction cycle
Ultrasonic extraction was applied at 60 °C when producing instant tea, and the proposed rate was increased by nearly 20 % compared with spray drying , and most of the effective fraction was completely extracted within 10 minutes of the ultrasonic treatment head .
Sixth, the application of ultrasonic circulation extraction technology in grain deep processing
Using ultrasonic extraction technology, high value-added ingredients can be extracted from rice bran, wheat bran, soybean, corn germ, etc., and the soy milk protein content is increased by 6 by ultrasonic treatment . 6%, by weight of dry bean extract 11 increase. 6 %. Ultrasonic extraction technology has the effect of increasing protein content and increasing yield for the production of traditional soybean products and modern processing new products such as soy milk, instant soy flour and protein isolates and protein concentrates.
Ultrasound also plays a very good role in the processing of wine. Ultrasonic plus high-frequency electromagnetic waves can shorten the ripening time of the wine, save hops, and have a good effect on the alcoholic treatment.
7. Application of ultrasonic circulation extraction technology in the detection of pollution-free agricultural products
The detection of pollution-free agricultural products must extract pesticide residues, harmful heavy metal substances and other harmful components in agricultural products as test samples. Ultrasonic extraction method is more convenient and rapid than conventional methods, and the extracted components are more than conventional methods.
