A device for decoction and extraction of Chinese medicinal materials

Abstract

The invention discloses a device for decocting and extracting Chinese herbal medicines, which comprises a tunnel-type decocting cabinet and a mobile loading cart. The bottom of the cabinet is provided with a heating pipe, a filter screen and a liquid outlet, and both sides of the cabinet are circular tracks. , The mobile storage car adopts a fully transparent filter structure, and the airtight doors are set on both sides of the cabinet body, which is movable forward and backward, and the pneumatic seal is used to form a sealed space inside the cabinet body. The company changes the size of the cabinet according to the actual production demand, increases the number of mobile storage carts, breaks through the limit of the boiling capacity of the traditional cooking tank, does not need to be boiled and fused in separate tanks, and is more in line with the pharmaceutical specifications of the Pharmacopoeia; the bottom heating tube type The design makes the internal medicinal materials more evenly heated and improves the conversion rate of effective substances in the medicinal materials; the overall equipment is installed on the ground, without the need for high-altitude operations, reducing potential safety hazards; the mobile loading vehicle loads Chinese medicinal materials to complete the feeding and decoction of medicinal materials , The whole process of unloading and cleaning makes the loading and unloading process easy to combine with the automatic assembly line, reducing manual operations.

Description

technical field [0001] The invention relates to the technical field of extracting traditional Chinese medicines, in particular to a device for decocting and extracting Chinese medicinal materials. Background technique [0002] Traditional Chinese medicine extraction methods include decoction, maceration, percolation, modified gelatin, reflux, solvent extraction, steam distillation and sublimation. Among them, boiling in water is the most commonly used method. [0003] At present, most of the equipment for decoction and extraction of traditional Chinese medicine use sealed traditional Chinese medicine extraction tanks, which are divided into the following two types according to the heating position: 1. Bottom heating type: upper opening for feeding and discharging; 2. Side heating type: upper opening for feeding , Lower opening discharge. [0004] Bottom heating type although the internal medicinal materials are evenly heated and the decoction effect is good, but it is very...

AI Technical Summary

Problems solved by technology

[0004] Bottom heating type although the internal medicinal materials are evenly heated and the decoction effect is good, but it is very troublesome when discharging and feeding materials. It is necessary to use an aircraft to hoist the medicinal material frame. During the high-altitude operation, the traditional Chinese medicine material frame is easy to shake and fall, which is harmful to the bottom workers. cause great safety hazard

[0005] The side heating type adopts the lower opening discharge method, although the discharge is convenient, but the solvent close to the tank wall will be heated first, and the heat flow will extend upwards, which will greatly delay the heating time of the solvent located in the center of the tank, resulting in uneven heating. Affect the quality of extraction, and at the same time, the discharge port at the bottom has extremely high requirements for sealing. Poor sealing may easily lead to safety accidents. The accident investigation team identified the direct cause of the accident: after the liquid leaked from the slag outlet at the bottom of the traditional Chinese medicine extraction tank, it splashed at high speed to generate static electricity, and the static charge accumulated and discharged, which ignited the explosive gas formed by the mixture of ethanol vapor and air around the extraction tank, resulting in an explosion. "

[0006] In addition to the disadvantages mentioned above, the existing tank-shaped traditional Chinese medicine extraction equipment has a limited diameter due to the requirement of sealing degree, resulting in a high overall height, which limits the volume, and at the same time, the feeding and discharging are cumbersome and not easy to clean; Liquid can only be extracted separately from multiple tanks and then fused, which does not meet the pharmaceutical specifications of the Pharmacopoeia
