The application of ultrasound in the medical field is well known, but the application of ultrasonic extraction technology in agricultural product processing is less well known.
Using ultrasonic extraction technology, useful components can be extracted from the fruits, roots, stems, and leaves of agricultural products, such as juice from apples, pears, oranges, strawberries, beets, carrots, spinach and other fruits. At the same time, ultrasonic treatment is beneficial to further refining the juice, degrading the pectin in the juice, reducing the viscosity of the juice, and improving the juice yield and juice quality.
Using ultrasonic technology, oil and spices can also be extracted from flowers, fruits, and seeds of agricultural products. For example, if ultrasonic technology is used to extract peanut oil, the extraction rate can be increased by more than 2 times. The use of ultrasonic technology to extract active ingredients from various Chinese medicinal materials and marine algae such as Artemisia annua, Cistanche deserticola, rhubarb, Gastrodia elata, and kelp has also achieved very good results.
Using ultrasonic extraction to extract pesticide residues in cod liver oil and rabbit meat and pork is also significantly better than the traditional Soxhlet extraction method.
In addition, compared with general process equipment such as propellers, colloid mills and homogenizers, the emulsion formed by ultrasonic emulsification has small and uniform droplets, stable emulsion, high efficiency and low cost, and can be used for juice, Preparation of margarine and salad oil, etc. During ultrasonic extraction and ultrasonic emulsification, the bacterial cell wall can be broken to cause bacterial death. At the same time, the ozone bubbles can be dispersed smaller, improving the sterilization ability, thereby achieving "cold sterilization" in the processing of agricultural products, which can replace the traditional high temperature Sterilize to avoid loss of nutrients and flavor in food.
Jinbaite's researchers have systematically studied the characteristics of various ultrasonic extractions, adopted biochemical engineering principles and technologies, solved various problems existing in traditional ultrasonic extraction, and developed products with independent intellectual property rights. patented technology. Jining Jinbaite Co., Ltd. has developed a series of complete sets of new continuous pipeline ultrasonic extraction devices suitable for my country's agricultural product processing enterprises, which can perform intermittent extraction and multi-stage continuous extraction at the same time. Main parameters such as extraction time, extraction temperature, and production speed can be set and automatically controlled. The extraction efficiency of our company's advanced extraction device is several to dozens of times that of conventional methods. The extraction pipe section can perform continuous dynamic extraction, and the extraction liquid and residue can be continuously discharged, which can save a lot of labor and improve the workshop production environment.
