How to deal with the problem of traditional Chinese medicine extract drying in microwave vacuum drying oven

The large-scale microwave vacuum drying oven is an important link in the production of traditional Chinese medicine It is widely used in the production of pharmaceutical excipients, APIs, intermediates and products, especially in the drying of traditional Chinese medicine extracts Its operation directly affects the function, quality, appearance and cost of products Nowadays, the drying of the extract depends on the traditional drying equipment, such as hot air circulation oven and microwave vacuum drying box In recent years, spray drying, vacuum freeze drying, microwave drying and vacuum drying have been applied in the drying process of Chinese medicine extract Due to the large viscosity and poor air permeability of traditional Chinese medicine extract, the drying process of traditional Chinese medicine extract has many disadvantages, such as long drying time, low output, high energy consumption, low production efficiency and product quality It is far from satisfied with the requirements of modernization, energy saving, environmental protection and advanced drying technology of traditional Chinese medicine extract In recent years, the microwave vacuum drying oven can be used to deal with the problem of traditional Chinese medicine extract drying The particles dried by microwave vacuum dryer have micropores in microstructure After directly destroying the required particle size, the fluidity of the particles is very good, which can be directly pressed into tablets or filled into capsules Together, because the particles have micro loose structure, good solubility and good appearance of the particles, the level of the products can be greatly improved with respect to the instant (powder) products The whole drying process is completely closed and does not contact with the external environment, which conforms to GMP Microwave vacuum drying equipment for traditional Chinese medicine extract Features: (1) low drying temperature, suitable for drying heat sensitive traditional Chinese medicine extract; (2) suitable for drying easily oxidized traditional Chinese medicine extract; (3) suitable for drying high concentration, high viscosity traditional Chinese medicine extract; (4) good dissolving function of the product, after the material is dried, it can be seen from the microstructure that there are micropores in the inner part, after the direct destruction to the required particle size, the fluidity of the particles is very good, because the particles have micro structure In the drying process, the product is always in the vacuum state, reducing product oxidation and making the material difficult to post Adhere to its original color, fragrance and taste in a more limited way to get high-quality final products Microwave vacuum drying oven is a full concept, energy-saving, environmental protection drying equipment It has been successfully applied to the drying of Salvia miltiorrhiza extract, Panax notoginseng extract, angelica extract as well as food malt extract, coffee, milk powder and so on As for food, because of its short drying time, low temperature and no oxidation in vacuum state, it also has a good preservation of fragrance; in the pharmaceutical field, some active substances, API, heat sensitive substances, vitamins, aromatic substances, etc have a good preservation of activity and fragrance.
