Description
本发明涉及设备自动控制技术领域，尤其涉及一种中草药提取液浓缩智能化控制***。The invention relates to the technical field of automatic device control, in particular to a centralized intelligent control system for extracting Chinese herbal medicine.
中药提取物是融合现代制药新技术的新型中药产品，它是通过对净药材或炮制品经浸出、澄清、过滤、蒸发等方法提取、纯化而制成的供中成药生产的原料产品，具有广阔的市场空间，在药品、食品、保健品、化妆品等诸多领域都被广泛应用，因而带动了一大批相关产业。在获得中药提取液之后，应根据其性质和浓缩程度的要求对中药提取液进行浓缩处理，常用的浓缩方法包括：Traditional Chinese medicine extract is a new type of traditional Chinese medicine product that integrates modern pharmaceutical new technology. It is a raw material product for the production of proprietary Chinese medicines by extracting and purifying the net medicinal materials or processed products by leaching, clarification, filtration and evaporation. The market space has been widely used in many fields such as medicines, food, health products, cosmetics, etc., thus driving a large number of related industries. After obtaining the Chinese medicine extract, the Chinese medicine extract should be concentrated according to its nature and concentration requirements. Commonly used concentration methods include:
1.常压浓缩：是在一个大气压下的蒸发浓缩，耗时较长，易导致某些成分破坏。适用于对热较稳定的药液的浓缩。常用的设备为敞口倾倒式夹层蒸汽锅，浓缩过程中应加强搅拌，避免表面结膜。若提取液含有乙醇或其他有机溶剂，则可采用常压蒸馏装置回收。1. Atmospheric pressure concentration: It is evaporation concentration at one atmosphere, which takes a long time and easily leads to the destruction of certain components. It is suitable for the concentration of liquids with relatively stable heat. The commonly used equipment is an open-dumping sandwich steamer. During the concentration process, the mixing should be strengthened to avoid surface conjunctiva. If the extract contains ethanol or other organic solvent, it can be recovered by an atmospheric distillation apparatus.
2.减压浓缩：是在降低蒸发器内的压力，在低于1个大气压下进行的蒸发浓缩。特点是：①溶液的沸点降低；②传热温度差增大，提高了蒸发效率；③能不断地排除溶剂蒸汽，有利于蒸发顺利进行；④沸点降低，可利用低压蒸汽或废气作加热源；⑤耗能大，因维持真空和由于沸点的降低，黏度增大，传热系数降低，增加了耗能。适用于含热敏性成分药液的浓缩；也可用于回收溶剂，但应注意因真空度过大或冷凝不充分造成乙醇等有机溶剂的损失。2. Concentration under reduced pressure: The pressure in the evaporator is lowered and concentrated by evaporation at less than 1 atmosphere. The characteristics are: 1 the boiling point of the solution is lowered; 2 the heat transfer temperature difference is increased, and the evaporation efficiency is improved; 3 the solvent vapor can be continuously removed, which is favorable for the evaporation to proceed smoothly; 4 the boiling point is lowered, and the low-pressure steam or the exhaust gas can be used as the heating source; 5 The energy consumption is large, because the vacuum is maintained and the boiling point is lowered, the viscosity is increased, the heat transfer coefficient is lowered, and the energy consumption is increased. It is suitable for concentration of liquids containing heat sensitive ingredients; it can also be used to recover solvents, but care should be taken to avoid the loss of organic solvents such as ethanol due to excessive vacuum or insufficient condensation.
具体地，减压浓缩常用设备：Specifically, the common equipment is concentrated under reduced pressure:
(1)减压蒸馏器：在减压及较低温度下使药液得到浓缩，同时可回收乙醇等有机溶剂。此设备回收乙醇的浓度一般在80％～85％，采用乙醇精馏塔
可提高回收乙醇的浓度。(1) Vacuum distillation distiller: The chemical solution is concentrated under reduced pressure and at a lower temperature, and an organic solvent such as ethanol can be recovered. The concentration of ethanol recovered from this equipment is generally 80%-85%, using ethanol distillation tower
It can increase the concentration of recovered ethanol.
(2)真空浓缩罐：用水流喷射泵抽气减压，适用于水提液的浓缩。(2) Vacuum concentration tank: pumping and decompressing with a water jet pump, suitable for concentration of water extract.
(3)管式蒸发器：蒸发器的加热室由管件构成，药液通过由蒸汽加热的管壁而被蒸发浓缩。有蛇管式、外加热式、中央循环管式及泵强制循环式。(3) Tube evaporator: The heating chamber of the evaporator is composed of a tube member which is evaporated and concentrated by a tube wall heated by steam. There are coil type, external heating type, central circulation tube type and pump forced circulation type.
(4)多效浓缩器：将前效所产生的二次蒸汽作为加热蒸汽引入另一串联的后效蒸发器组成的蒸发装置，由于二次蒸汽的反复利用，可组成多效蒸发器，节省能源，提高蒸发效率。(4) Multi-effect concentrator: the secondary steam generated by the pre-effect is introduced as heating steam into the evaporation device composed of another series-connected after-effect evaporator. Due to the repeated use of the secondary steam, a multi-effect evaporator can be formed, saving Energy to improve evaporation efficiency.
3.薄膜浓缩：指药液在快速流经加热面时，形成薄膜并且因剧烈沸腾产生大量的泡沫，达到增加蒸发面积，显著提高蒸发效率的浓缩方法。其特点是：①浸提液的浓缩速度快，受热时间短；②不受液体静压和过热影响，成分不易被破坏；③可在常压或减压下进行连续操作；④溶剂可回收重复使用。各种薄膜浓缩器均适用于热敏性药液的浓缩和溶剂的回收，但由于结构不同而具有不同的特点与适用性。3. Film concentration: refers to the concentration method in which the liquid forms a film when it flows rapidly through the heating surface and generates a large amount of foam due to vigorous boiling, thereby increasing the evaporation area and significantly increasing the evaporation efficiency. The characteristics are as follows: 1 the concentration of the leach liquor is fast, the heating time is short; 2 is not affected by hydrostatic pressure and overheating, the composition is not easily destroyed; 3 can be continuously operated under normal pressure or reduced pressure; 4 solvent can be recycled repeatedly use. Various film concentrators are suitable for the concentration of heat sensitive liquids and the recovery of solvents, but have different characteristics and applicability due to different structures.
(1)升膜式蒸发器：预热的药液经列管式蒸发器底部进入，受热立即沸腾汽化生成的大量泡沫及二次蒸汽，沿加热管高速上升，通过加热管并在内壁上形成液膜，被快速蒸发浓缩。适用于蒸发量较大，热敏性、黏度适中和易产生泡沫的料液。不适用于高黏度、有结晶析出或易结垢的料液。一般中药水提液可浓缩相对密度达1.05～1.10。(1) Ascending membrane evaporator: The preheated chemical liquid enters through the bottom of the tube-type evaporator, and a large amount of foam and secondary steam generated by vaporization immediately after being heated, rises rapidly along the heating pipe, passes through the heating pipe and forms on the inner wall. The liquid film was concentrated by evaporation. It is suitable for liquids with large evaporation, heat sensitivity, moderate viscosity and easy foam generation. Not suitable for high viscosity, crystallization or fouling. Generally, the traditional Chinese medicine aqueous extract can be concentrated to a relative density of 1.05 to 1.10.
(2)降膜式蒸发器：药液由顶部加入，在重力下成膜，适于蒸发浓度较高、黏度较大的药液。由于没有液体静压，沸腾传热系数与温度差无关，即使在较低传热温度差下，传热系数也较大，对热敏性药液的浓缩更有益。医`学敎育网搜`集整理(2) Falling film evaporator: The liquid is added from the top and forms a film under gravity, which is suitable for evaporating liquid with high concentration and high viscosity. Since there is no hydrostatic pressure, the boiling heat transfer coefficient is independent of the temperature difference. Even at a lower heat transfer temperature difference, the heat transfer coefficient is larger, which is more beneficial for the concentration of the heat sensitive liquid. Medical school
(3)刮板式薄膜蒸发器：利用高速旋转的刮板转子，将药液刮布成均匀的薄膜而进行蒸发浓缩。由于在真空条件下，药液在沸腾区停留时间短，故适于高黏度、易结垢、热敏性药液的蒸发浓缩。但结构复杂，动力消耗大。(3) Scraper type thin film evaporator: The liquid medicine is scraped into a uniform film by a high speed rotating squeegee rotor to carry out evaporation and concentration. Since the residence time of the chemical solution in the boiling zone is short under vacuum conditions, it is suitable for evaporation and concentration of high viscosity, easy scaling and heat sensitive chemical liquid. However, the structure is complicated and the power consumption is large.
(4)离心式薄膜蒸发器：通过离心使药液分布成0.05～1mm的薄膜，再通
过锥形盘加热面被蒸发浓缩。由于传热系数高、受热时间短，故适于高热敏性物料蒸发浓缩。该设备蒸发效率高，但结构复杂，价格较贵。(4) Centrifugal thin film evaporator: the liquid medicine is distributed into a film of 0.05 to 1 mm by centrifugation, and then re-passed.
The heated surface of the conical disk is concentrated by evaporation. Because of high heat transfer coefficient and short heating time, it is suitable for evaporation and concentration of high heat sensitive materials. The device has high evaporation efficiency, but the structure is complicated and the price is relatively expensive.
现有的中药提取液浓缩处理时，是根据其性质和浓缩程度的要求采用相应地方法和设备，由人工进行生产过程控制，生产人员通过现场仪表及手动阀门、泵及电机等让浓缩***运行起来，在过生产运行过程中核心参数不能准确及时的控制，例如：温度必须控制在原蒸发温度的±1度之内；压力必须控制在设定压力的±10mbar之内；产品比重三的精确度达到小数点后两位数。When the existing traditional Chinese medicine extract is concentrated, the corresponding method and equipment are adopted according to the requirements of its nature and concentration degree, and the production process is controlled manually. The production personnel let the concentrated system run through the on-site instrument and manual valves, pumps and motors. In the process of production and operation, the core parameters cannot be accurately and timely controlled. For example, the temperature must be controlled within ±1 degree of the original evaporation temperature; the pressure must be controlled within ±10 mbar of the set pressure; the accuracy of the product specific gravity three Double digits after reaching the decimal point.
