Description
Technical field
The invention belongs to grinding and processing field, be specifically related to a kind of cold cycle and pulverize drying device, and be specifically related to make
Fresh Radix Notoginseng powder, the method for fresh Radix Notoginseng liquid is prepared with it.
Background technology
Existing pulverizing and drying equipment are usually associated with high temperature and high heat when operation, but but to most materials
Effective ingredient cause strong influence, the heat sensitive materials such as medicine, food, chemicals are become apparent from.As at " medicine pill
The research of normal temperature drying technology and application " literary composition in just point out: " when Herba Menthae, Rhizoma Sparganii use 70 degree of hot air dryings, although it is
As long as high material temperature 68.5 and 67 degree, its index components is lost the most completely, when Radix Trichosanthis uses 70 degree of hot air dryings, and its index
Composition have lost more than 2/3, and when Rhizoma Curcumae, the Radix Paeoniae Alba use 70 degree of hot air dryings, its index components have lost more than 60%,
When Radix Isatidis uses the alternating temperature hot air drying of less than 60 degree, its index components has lost 59.2%, and Radix Et Rhizoma Rhei, Radix Saposhnikoviae use 80
During alternating temperature hot air drying below spending, although the highest material temperature only 70.2 degree, its index components have lost more than 40% ".
Typically under conditions of temperature is less than 50 degrees Celsius, it is dried referred to as normal temperature drying, because natural under sunshine
It is dried and also can reach this temperature.The normal temperature drying process carried out less than 50 degrees Celsius is optimum drying process.Temperature is the lowest, dry
During dry, the loss of index components is the least, but in general, its drying time is the longest, and energy consumption for drying is the biggest.But it is existing
Equipment and method are the slowest the temperature dried material speed of less than 50 degree Celsius, the most several hours, tens days at most.
Radix Notoginseng (Panax Notoginseng) has another name called Radix Notoginseng, is a jewel in Chinese crude drug, the pharmacy man that the Ming Dynasty is famous
Li Shizhen (1518-1593 A.D.) is called " Radix Stephaniae Sinicae (Radix Stephaniae Dielsianae) "；Chinese patent medicine " YUNNAN BAIYAO " and the primary raw material of " sheet son is yellow " for China and foreign countries of becoming famous.
The processing method of Radix Notoginseng powder mostly is: dries, dry or dries as dry Radix Notoginseng, further powder after being cleaned by fresh Radix Notoginseng
Broken prepared Radix Notoginseng powder.But the method not only needs substantial amounts of time, material resources and financial resources carry out Radix Notoginseng drying and pulverize.And
During processing, effective ingredient and the active substance of Radix Notoginseng are constantly lost and are wasted." fresh Radix Notoginseng, dry Radix Notoginseng and
Active pseudo-ginseng saponin content compares " research point out: Radix Notoginseng total arasaponins main component (ginsenoside Rg1, Rb1, arasaponin
R1) content is: fresh Radix Notoginseng > dry Radix Notoginseng > Active pseudo-ginseng saponin.
Meanwhile, Radix Notoginseng also contains abundant volatile material, such as terpenes, alcohols, aldehydes, olefines and alkanes, its
Middle terpenes is the main matter in volatile ingredient, has abundant activity.But during traditional method is drying, high
Wen Gaore and the time longer volatile material that causes are by substantial amounts of loss.
Although ultralow temperature lyophilizing crushing technology solves directly from the processing technique of fresh Radix Notoginseng processing powder process, solve Radix Notoginseng
Active substance loss, but the method is higher to the requirement of equipment, relatively costly, is not suitable for the development of industrialization.And
The Radix Notoginseng lyophilized powder prepared easily absorbs water and the moisture absorption, and is unfavorable for storing.
Therefore, the course of processing of Radix Notoginseng the most comprehensively keeps the original effective ingredient of Radix Notoginseng and activity,
How to control production cost, accomplish energy-conserving and environment-protective, be prone to industrialization produce, what always Radix Notoginseng industrialization was explored diligently asks
Topic.
Equally, being not only Radix Notoginseng and Chinese crude drug, also numerous food product, chemicals, agricultural product and heat-sensitive materials are required for low
Temperature is pulverized, is dried and concentrated.Therefore, market is needed a efficient, energy-conservation low-temperature grinding drying device badly.
