Traditional Chinese medicine extraction and concentration equipment is suitable for various processes such as atmospheric pressure, micro pressure, water decoction, warm immersion, heat reflux, infiltration, extraction of aromatic oil components and recovery of organic solvents in traditional Chinese medicine, plants, food, beverage, chemical and other industries. Dynamic extraction and concentration, short time and high efficiency . Traditional Chinese medicines contain complex chemical components, usually sugars, amino acids, proteins, oils, waxes, enzymes, pigments, vitamins, organic acids, tannins, inorganic salts, volatile oils, alkaloids, and terpenoids. Among these ingredients, there are active ingredients and ineffective impurities. If the impurities are not removed as much as possible, the quality and stability of the preparation will be affected.
First, the leak of various components
Because the leakage of a component in the concentrating device penetrates into the air, the vacuum is reduced, such as the head, the manhole, the pipe wall, the flange seal, the condenser, the vacuum pipe, the material pipe, the inlet and outlet valves, the discharge pump, and the second Parts such as secondary steam pipes and damage to the gasket.
Second, the inlet temperature of the cooling water is consistent, but the flow is insufficient.
1. In the case of using tap water or reservoir, although the inlet pump is running normally, but due to the sudden drop of the pressure of the tap water itself, or the liquid level of the reservoir is lowered, the original opening degree of the valve on the inlet pipe of the inlet pump has been Can not meet the requirements of the original flow, should be adjusted in time;
2. There is foreign matter or inlet blockage in the inlet water pump and pipeline of the cooling water.
Third, the heating steam pressure is too large
The use pressure of the heated steam exceeds the normal value, which promotes the gasification of the milk, and the secondary steam generated is not sufficiently condensed.
Fourth, the inlet water temperature of the cooling water is too high
The inlet water temperature of the cooling water is one of the main parameters that must be strictly controlled and adjusted during operation. In the concentration equipment using the water jet, the inlet water temperature of the cooling water should be controlled at 25~30 °C. However, due to the unreasonable use of weather or return water, the inlet water temperature of the cooling water will far exceed the upper limit of the above temperature. In the southern part of the country, in the hot summer, the outdoor temperature is above 35 °C, and the temperature of the tap water or river water exceeds 30 °C. In this case, the water of the condensate of the concentrating equipment is cooled by the cooling tower, but the temperature cannot exceed 30. °C tap water or drinking water is used as the cooling water for the concentration equipment, otherwise it will affect the vacuum of the Chinese medicine extraction equipment.
