Characteristics and application technology of circular ultrasonic extractor

The circulating ultrasonic extractor adopts the mode of high-power multi-stage concentrated energy ultrasonic The high-power ultrasonic field directly acts on the extracted material The ultrasonic energy utilization rate is high and the extraction effect is remarkable The equipment is designed and produced in strict accordance with GMP standards, with wide applicability and high cost performance It is an excellent choice for small and medium-sized biochemical research extraction equipment, new pharmaceutical plants and GMP transformation extraction equipment The equipment characteristics of the circular ultrasonic extractor are as follows: 1 High efficiency adopts mechanical agitation and ultrasonic circulation to enhance the extraction, and the extraction time is short (a few to a few tenths of the conventional method), so the working efficiency is high 2 Low energy consumption and small function ultrasonic can crush and extract a large number of materials, which are generally extracted at room temperature, without high-power stirring and consuming a large amount of heating energy The energy consumption per unit material treatment capacity is reduced by more than 50% compared with the conventional extraction method 3 High quality of extracted products due to the low extraction temperature, the original effective ingredients (especially the thermosensitive ingredients) in the material are kept to the maximum extent, so as to improve the efficacy and reduce the dosage At the same time, due to the short extraction time, the content of other useless impurities in the extracted product is reduced, the quality of the extracted product is improved, which lays a good foundation for the subsequent separation and purification process, and can significantly reduce the production cost of other high-end products such as single component 4 The high extraction rate of the target extract is due to the use of ultrasonic breaking extraction technology, which can fully release the effective ingredients in the medicinal materials, so as to improve the extraction rate of the target extract 5 It can be widely used in volatile or non-volatile extraction media, and in the extraction of various effective ingredients and natural products It is applicable to all kinds of agricultural and sideline products, fruits and melons, Chinese herbal medicines, land and marine animals, plants and microbial fermentation products to extract all kinds of natural product ingredients needed for food, natural additives, natural pigments, beverages, medicine, health products, cosmetics, biology, etc the products can be granules or extraction solutions It is suitable for laboratory research, new natural products and agricultural products deep processing and extraction workshop as well as improvement of existing extraction process and equipment In addition, it can also be used for ultrasonic dispersion, preparation of sustained-release drug microcapsules and preparation of nanocapsules 6 High degree of automation, easy operation, extraction time, extraction temperature, circulation speed and other main parameters can be set or automatically controlled, which reduces the impact of factors on product quality and helps to ensure product quality According to the needs of production, the cyclic ultrasonic extraction equipment can be designed and manufactured according to the needs of users, and can also be added to the computer control system for production control 7 There are various ultrasonic modes, single, double and multi frequency 8 The extraction process is completely closed, clean and sanitary, and the contact surface with the material is made of stainless steel, meeting the GMP requirements 9 The whole machine is small in size and low in height, which saves workshop construction investment, and is also convenient for maintenance, cleaning and disinfection 10 The registration of new drug research is limited by certain laws and regulations According to the drug registration law, the change of extraction process needs to be re verified in clinical practice The enterprises that use it are under pressure and the research units have no problems in using it The application of ultrasonic extraction technology: 1 The application of ultrasonic extraction technology in the deep processing of grain Ultrasonic extraction technology can extract high value-added components from rice bran, wheat bran, soybean, corn germ and so on Ultrasonic treatment can increase the protein content of soybean milk by 6.6% and the dry matter weight of soybean milk by 11.6% In addition, ultrasound also plays a very good role in the processing of wine (previously mentioned in the article on the use of ultrasonic cell breaker) 2 The cyclic ultrasonic extraction technology has many advantages in the deep processing of oil It can replace the traditional processing method in many kinds of oil processing, reduce the processing cost and improve the product quality Extraction of vegetable oil: under the treatment of ultrasound, the extraction rate of peanut oil can be increased by 2.8 times; the extraction rate of oil from oil seeds by ultrasound can be increased by 8.3 times; the extraction rate of oil from sunflower seeds can be increased by 27-28% by adding ultrasound; the extraction rate of oil from cotton seeds by ethanol can be increased by 83% by using ultrasound Aromatic oil extraction: extract essential oil from orange peel The extraction rate of 10 minutes by ultrasonic method is more than 2 times higher than that of conventional extraction method Animal oil processing: ultrasonic extraction method can be used in a very short time（ 2-10min) can make animal oil free, and the vitamins in the oil are not damaged, and the oil is clear; for example, when cod liver oil is extracted from cod liver, the oil content in cod liver can be completely free within 2-5min by ultrasonic extraction method, and the oil yield is close to the oil content of raw material, which is much higher than that of conventional extraction method (70%), and the oil quality is significantly better than that of conventional extraction method 。 3 The application of circular ultrasonic extraction technology in the deep processing of sugar material to extract sugar from beet The ultrasonic extraction method can shorten the extraction time by half, increase the yield by 12-14%, and increase the extraction speed of sugar by 78% 4 Application of circular ultrasonic extraction technology in deep processing of fruits and vegetables Ultrasound is conducive to further refining of pulp, degradation of pectin in juice and reduction of viscosity of juice, so as to improve the output, quality and filtration speed of juice At the same time, the plant cells are broken after ultrasonic treatment, which significantly improves the digestibility and absorption rate of nutrients of human body and animals 5 the application of circular ultrasonic extraction technology in tea intensive processing When producing instant tea, the ultrasonic extraction method was applied at 60 degrees Celsius The proposed rate increased by nearly 20% compared with spray drying, and most of the effective components were extracted in ultrasonic treatment head 10min 6 cycle ultrasonic extraction technology was applied in the intensive processing of Chinese medicinal materials At present, the cyclic ultrasonic extraction technology and device have been successfully used in the extraction of natural products from dozens of Chinese medicinal materials, such as terpenoids, lactones, flavonoids, alkaloids, glycosides, polysaccharides, tea polyphenols, and the solvent extraction coupling integrated extraction and purification 7 The application of circular ultrasonic extraction technology in the detection of pollution-free agricultural products the pesticide residues, harmful heavy metals and other harmful components in agricultural products must be extracted for the detection of pollution-free agricultural products As the detection sample, the conventional Soxhlet extraction method is time-consuming and complicated The ultrasonic extraction method is convenient and fast, and the extracted components are more than the conventional extraction method The circular ultrasonic extractor has high ultrasonic field strength and strong cavitation effect It is suitable for Chinese medicine, health care products, cosmetics and other related enterprises to use volatile or non-volatile solvents to extract effective ingredients from various land and marine raw materials, especially for the extraction of raw materials from rhizomes that are difficult to be broken It is difficult to extract and has high added value It is recommended to use the ultrasonic circulation extractor
