Equipment for decoction and extraction of traditional Chinese medicinal materials

Abstract

The invention discloses equipment for decoction and extraction of traditional Chinese medicinal materials. The equipment includes a tunnel type decocting cabinet and movable material containing trolleys. The bottom of the cabinet body is provided with a heating pipe and a filter screen and a liquid outlet. A circulation track is arranged at two sides of the cabinet body. The movable material containing trolley adopts a full-transparent filter screen structure. Air-tight doors are arranged on the two sides of the cabinet body and move forwards and backwards. A sealed space is formed in the cabinet body through pneumatic sealing. An enterprise changes the size of the cabinet body according to actual production requirements, the number of the movable material containing trolleys is increased,the limitation of decocting capacity of a traditional decocting tank is broken through, separate-tank decocting fusion is not needed, and the cabinet better conforms to the pharmaceutical specification of the pharmacopeia. Due to the heating pipe type design at the bottom, internal medicinal materials are heated more uniformly, and the conversion rate of effective substances in the medicinal materials is increased. The whole equipment is arranged on the ground, aloft work is not needed, and potential safety hazards are reduced. The movable material containing trolleys are used for loading traditional Chinese medicinal materials, the whole process of feeding, decocting, discharging and cleaning of the medicinal materials is completed, the feeding and discharging process can be convenientlycombined with an automatic assembly line, and manual operation is reduced.

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
