Embodiment 1

[0025] Example 1 High-efficiency and energy-saving extraction tank structure and operation process

[0026] As attached figure 1 As shown, the main components of the extraction tank of the present invention include the body 1, the stirring blade 2, the upper heating jacket 3 and the lower heating jacket 5, which have the same or similar structure as the existing extraction tank. The outer wall of the tank 1 is provided with an upper ultrasonic transducer 4 and a lower ultrasonic transducer 6, the upper ultrasonic transducer 4 is a group of 6, and the lower ultrasonic transducer 6 is a group of six, all cylindrical The arc structure is inlaid on the upper and lower parts of the outer wall of the tank 1, and is arranged alternately along the outer wall of the tank 1 in a bottom-up order.

[0027] During the extraction of Chinese herbal medicine pieces, the Chinese herbal medicine pieces and the extraction solvent are added to the tank 1 in proportion. When heating is started in the f...

Embodiment 3

[0031] Example 3 Comparison test of extraction energy consumption in high efficiency and energy saving extraction tank

[0032] The high-efficiency and energy-saving extraction tank of the present invention (the effective extraction volume of the extraction tank is 3m 3 , The upper ultrasonic transducer 4 and the lower ultrasonic transducer 6 are in groups of 6) decocting 2000kg of purified water, a total of 6 sets of experiments are set up, of which the first, second, and third sets of experiments turn on the upper and lower ultrasonic waves Transducers, the 4th, 5th, and 6th group tests close the upper and lower ultrasonic transducers.

[0033] The steam pressure and temperature used in the 6 groups of tests remained the same, and the opening sizes of the steam valves of the upper heating jacket 3 and the lower heating jacket 5 were also the same. The initial temperature of the purified water used in the 6 groups of experiments was 22°C. When the temperature of the purified water...

Abstract

The invention discloses a high-efficiency and energy-saving extraction tank which is mainly composed of a tank body 1, a stirring blade 2, an upper heating jacket 3 and a lower heating jacket 5. In particular, the outer wall of the tank body 1 is provided with an upper ultrasonic transducer 4 and a lower ultrasonic transducer 6. The ultrasonic transducers are each of a cylindrical arc structure, are laid in the upper part and the lower part of the outer wall of the tank body 1 respectively, and are arranged along the outer wall of the tank body 1 from bottom to top in a layered interactive manner. The high-efficiency and energy-saving extraction tank has the advantages of reasonable structure, scientific design and convenient operation. The ultrasonic transducers can act on a thermal resistance boundary formed by the tank wall and an extracting solvent, the convective heat and mass transfer are strengthened, the heat convective resistance is reduced and the boiling of the extracting solvent is accelerated, so the time from heating to boiling is significantly shortened, the time cost and the energy consumption cost are saved, and the current requirements of green production of traditional Chinese medicines are met.

Description

Technical field [0001] The invention relates to a high-efficiency and energy-saving extraction tank, which is suitable for the extraction of Chinese medicine decoction pieces and belongs to the field of Chinese medicine pharmaceutical equipment. Background technique [0002] Extraction refers to the process of extracting the active ingredients or effective parts contained in the Chinese herbal medicine pieces with appropriate solvents and methods. In order to make suitable medicinal preparations or reduce the dosage, most Chinese medicinal pieces need to be extracted. The curative effect of Chinese medicinal preparations depends to a large extent on whether the methods of extracting and refining the Chinese medicine are appropriate and whether the technological process is scientific and reasonable. The selection of extraction methods for traditional Chinese medicine should be determined based on the comprehensive considerations of the characteristics of the prescription decoction...
