Problems solved by technology

Most of Panax notoginseng and Panax notoginseng tablets are dried with hot air, which takes a long time to dry, contains a lot of soil, is difficult to clean, and has a hard texture, which causes a large loss in crushing, and the active ingredients are not easy to dissolve; Panax notoginseng powder has a finer particle size and is easily Sticking to the wall, taking a large amount, and the dosage is not easy to control, and it is inconvenient to eat; freeze-dried notoginseng and freeze-dried notoginseng powder have low moisture content, high hygroscopicity, and are not easy to store, and the production cycle is long and the production efficiency is low. higher cost
However, it takes a long time, especially the pre-freezing time reaches 25 hours, resulting in higher processing costs; in addition, the notoginseng drying is not thorough, the water cannot be completely removed, and the finished product of notoginseng produced is soft and not crisp, so it is difficult to guarantee three 7. The quality of products such as traditional Chinese medicine granules affects the application and promotion of Panax notoginseng products.

Abstract

The invention relates to a pseudo-ginseng vacuum freeze-drying method and application thereof, and relates to the technical field of traditional Chinese medicine processing. According to the vacuum freeze-drying method, pseudo-ginseng homogenate is subjected to pre-freezing and vacuum drying treatment, in the pre-freezing step, pre-freezing is carried out in stages at the temperature of minus 20-minus 75 DEG C, and in the vacuum drying treatment step, vacuum drying is carried out at the temperature of minus 20-30 DEG C. The vacuum freeze-drying method is applied to preparation of pseudo-ginseng processed products, and the obtained pseudo-ginseng processed products are high in cleanliness, fine and smooth in taste, stable in quality, accurate in dosage, convenient to apply and carry, high in dissolution and absorption speed, higher in product standardization, higher in production efficiency and suitable for daily life of normal people.

Description

【Technical field】 [0001] The invention belongs to the technical field of traditional Chinese medicine processing, and in particular relates to a method for vacuum freeze-drying of notoginseng and its application. 【Background technique】 [0002] Panax notoginseng is one of the traditional precious Chinese medicines. The common products include notoginseng, panax notoginseng tablets, and panax notoginseng powder. In recent years, due to the development of science and technology, freeze-dried panax notoginseng and panax notoginseng powder have gradually appeared on the market. Most of Panax notoginseng and Panax notoginseng tablets are dried with hot air, which takes a long time to dry, contains a lot of soil, is difficult to clean, and has a hard texture, which causes a large loss in crushing, and the active ingredients are not easy to dissolve; Panax notoginseng powder has a finer particle size and is easily Sticking to the wall, taking a large amount, and the dosage is not e...
