Detailed description of extraction and concentration equipment of traditional Chinese Medicine

The extraction and concentration equipment of traditional Chinese medicine is suitable for various processes of traditional Chinese medicine, plant, food, beverage, chemical industry, such as atmospheric pressure, micro pressure, water decocting, warm soaking, hot reflux, infiltration, extraction of aromatic oil components and recovery of organic solvents Dynamic extraction and concentration are adopted, with short time and high efficiency The chemical composition of traditional Chinese medicine is very complex, including sugar, amino acid, protein, oil, wax, enzyme, pigment, vitamin, organic acid, tannin, inorganic salt, volatile oil, alkaloid, glycoside, etc There are both effective ingredients and invalid impurities in these ingredients If the impurities are not removed as much as possible, the quality and stability of the preparation will be affected 1、 Leakage of each component: the leakage of a component in the concentration equipment causes the air to infiltrate, leading to the decrease of vacuum degree, such as the damage of the head, manhole, pipe wall, flange sealing port, condenser, vacuum pumping pipe, material pipe, inlet and outlet valve, discharge pump, secondary steam pipe and sealing gasket 2 The inlet temperature of the cooling water is in conformity with the requirements, but the flow is less than 1 In the case of using tap water or water reservoir, although the inlet pump operates normally, the original opening degree of the valve on the inlet pipe of the inlet pump cannot meet the requirements of the original flow due to the sudden drop of the pressure of tap water itself or the drop of the liquid level of the water reservoir, and it shall be adjusted in time; 2 The inlet pump and pipe of the cooling water have foreign matters or the inlet is blocked 3 The pressure of heating steam is too high The use pressure of heating steam exceeds the normal value, which makes the milk gasification intensified and the secondary steam generated cannot be fully condensed IV the inlet temperature of the cooling water is too high The inlet temperature of the cooling water is one of the main parameters that must be strictly controlled and regulated in the operation process In the concentration equipment using the hydraulic injector, the inlet temperature of the cooling water should be controlled within 25 ~ 30 ℃ However, due to the weather or unreasonable use of recycled water, the inlet temperature of cooling water will far exceed the upper limit of the above temperature In the south of China, the outdoor temperature is as high as 35 ℃ in hot summer, and the temperature of tap water or river water is over 30 ℃ In this case, the discharge water of condensation water of concentration equipment can not be mixed with tap water or drinking water whose temperature is over 30 ℃ as the cooling water of concentration equipment, although it is cooled by cooling tower, otherwise the vacuum degree of extraction equipment of traditional Chinese medicine will be affected.
