Description
Technical field
The invention belongs to crushing and processing fields, and in particular to a kind of low-temperature circulating crushes drying device, and more particularly to making
The method for preparing fresh Radix Notoginseng powder, fresh Radix Notoginseng liquid with it.
Background technique
Existing crushing and drying equipment are usually associated with high temperature and high fever in operation, however but to most materials
Effective component cause strong influence, the heat sensitive materials such as drug, food, chemicals are become apparent from.Such as in " medicine pill
The research and application of air drying technology " text in just point out: " when peppermint, trigone are using 70 degree of heated-air dryings, although it is most
As long as high material temperature 68.5 and 67 degree, index components are lost completely, when radices trichosanthis uses 70 degree of heated-air dryings, index
Ingredient has had lost 2/3 or more, and when curcuma zedoary, Radix Paeoniae Alba use 70 degree of heated-air dryings, index components have had lost 60% or more,
When Radix Isatidis uses 60 degree of alternating temperature heated-air dryings below, index components have lost 59.2%, and rheum officinale, radix saposhnikoviae use 80
When alternating temperature heated-air drying below spending, although only 70.2 degree of highest material temperature, index components have had lost 40% or more ".
Referred to as air drying generally is dried under conditions of temperature is lower than 50 degrees Celsius, because natural under sunshine
Drying can also reach the temperature.The air drying process carried out lower than 50 degrees Celsius is optimum drying process.Temperature is lower, does
The loss of index components is smaller during dry, but in general, drying time is longer, and energy consumption for drying is also bigger.However it is existing
Device and method are all relatively slow in 50 degree Celsius temperature dried material speed below, few then several hours, and more then more than ten days.
Radix Notoginseng (Panax Notoginseng) also known as pseudo-ginseng are a jewel in Chinese medicine, famous pharmacy man, the Ming Dynasty
Li Shizhen (1518-1593 A.D.) is called " invaluable "；For the Chinese patent drug " Yunnan Baiyao " for China and foreign countries of becoming famous and the primary raw material of " piece is young yellow ".
The processing method of Radix Notoginseng powder is mostly: drying, dries or dry after fresh Radix Notoginseng is cleaned as dry Radix Notoginseng, further powder
Broken obtained Radix Notoginseng powder.However the method not only needs a large amount of time, material resources and financial resources to carry out drying to Radix Notoginseng and crush.And
During the treatment, the effective component of Radix Notoginseng and active material are constantly lost and are wasted." fresh Radix Notoginseng, dry Radix Notoginseng and
Active pseudo-ginseng saponin content compares " research point out: arasaponin main component (ginsenoside Rg1, Rb1, notoginsenoside
R1 content) are as follows: fresh Radix Notoginseng > dry Radix Notoginseng > Active pseudo-ginseng saponin(e.
Meanwhile Radix Notoginseng also volatile materials rich in, such as terpenes, alcohols, aldehydes, olefines and alkanes,
Middle terpenes are the main matter in volatile component, have activity abundant.It is high however during conventional method is drying
Warm high fever and the time longer volatile materials that causes largely are lost.
Although ultralow temperature freeze-drying crushing technology solves the processing technology for directly processing powder processed from fresh Radix Notoginseng, solves Radix Notoginseng
Active material loss, but this method, to the more demanding of equipment, higher cost is not suitable for the development of industrialization.And
Radix Notoginseng freeze-dried powder obtained is easy water suction and the moisture absorption, is unfavorable for storing.
Therefore, how the original effective component of Radix Notoginseng and activity are comprehensively kept as far as possible in the process of Radix Notoginseng,
How to control production cost, accomplish energy conservation and environmental protection, be easy to industrialization production, be always Radix Notoginseng industrialization explore diligently ask
Topic.
Equally, Radix Notoginseng and Chinese medicine are not only, there are many more food, chemicals, agricultural product and heat-sensitive materials require it is low
Temperature crushing, dry and concentration.Therefore, a efficient, energy-efficient low-temperature grinding drying device is needed in the market.
Summary of the invention
