Description

Technical Field

[0001] The utility model belongs to the field of concentrating traditional Chinese medicine clear liquid, and relates to a device for concentrating traditional Chinese medicine clear liquid. Background Art

[0002] Alcohol precipitation of traditional Chinese medicine is a method that utilizes the characteristics of most effective ingredients in traditional Chinese medicine, such as alkaloid salts, glycosides, organic acid salts, amino acids, polysaccharides, etc., which are easily soluble in water and alcohol. The ingredients are extracted with water, and then appropriate ethanol is added for repeated precipitation. The insoluble impurities are filtered out to finally obtain a clear liquid. Alcohol precipitation is the most commonly used method for preparing injections and oral liquids from traditional Chinese medicine. The traditional Chinese medicine liquid is extracted several times to obtain a traditional Chinese medicine clear liquid. After obtaining the traditional Chinese medicine clear liquid, the extract is concentrated to finally obtain a medicinal slurry. However, in the existing traditional Chinese medicine clear liquid concentration process, the concentration tank is generally heated so that the concentration tank gradually absorbs heat, thereby removing the water contained in the traditional Chinese medicine clear liquid. This process is relatively slow and the generated water is not discharged in time, resulting in a low efficiency in the concentration of the traditional Chinese medicine clear liquid. Therefore, in order to solve the above-mentioned technical problems, the technical solution of the present application is provided. Utility Model Content

A heating structure is connected to the bottom of the outer wall of the concentrating tank body 1, and the heating structure surrounds the bottom of the concentrating tank body 1.

[0025] The specific implementation method of this embodiment is as follows: several support frames connected to the outer wall of the concentration tank body are used to support the entire concentration tank body, the infusion tube connected to one side of the concentration tank body is used to transport the Chinese medicine clear liquid to be concentrated into the concentration tank body, the exhaust pipe connected to the top of the concentration tank body is used to discharge the water vapor generated during the concentration of the Chinese medicine clear liquid, the vacuum structure connected to the other side of the concentration tank body is used to extract the water vapor inside the concentration tank body, so as to avoid the water vapor cooling to form liquid and mixing with the medicinal slurry again, the heating mechanism is arranged on the other side of the concentration tank body, the heating mechanism is used to evaporate the liquid in the Chinese medicine liquid, and then form water vapor, so as to achieve the purpose of quickly heating the Chinese medicine liquid, the concentration tank body is used to connect the heating structure, the heating structure is used to provide heat to the medicinal slurry after preliminary concentration again, so as to facilitate further concentration of the medicinal slurry.

[0026] The Chinese herbal medicine liquid to be concentrated is transported to the interior of the concentration tank through an infusion tube, and the heating mechanism is started at the same time. The Chinese herbal medicine liquid enters the heating mechanism and directly absorbs heat, so that the liquid in the Chinese herbal medicine liquid quickly turns into water vapor, and then the water vapor and the Chinese herbal medicine liquid return to the interior of the concentration tank. At this time, the vacuum structure is started to work, so that the water vapor inside the concentration tank is extracted, and the above operation is continuously repeated until a preliminary medicinal slurry is obtained.

[0031] The specific implementation method of this embodiment is: during the operation of the vacuum pump, the water vapor on the upper part of the concentration tank body is sucked away through the suction pipe, and the water vapor is discharged through the exhaust pipe, thereby forming a negative pressure state on the upper part of the concentration tank body, avoiding the problem of water vapor staying on the upper part of the inner wall of the concentration tank body and cooling again to form liquid.

[0032] The two sides of the heat exchanger are connected to the air inlet pipe and the drain pipe respectively. The air inlet pipe inputs high-temperature, high-pressure water vapor, so that the traditional Chinese medicine liquid entering the heat exchanger directly and quickly absorbs heat, and the water vapor that loses heat is cooled to become liquid and discharged through the drain pipe.
