Description
Technical field
The invention belongs to Chinese medicine preparation fields, and in particular to a kind of production method for improving pinecone clear cream melting.
Background technique
In pharmaceutical production, as needed, medicinal extract is processed into dry powder by commonly used dry technology, and dry technology generallys use
Spray drying technology, the application constantly extension in the field of Chinese medicines, plays an important role in, drying principles are usual are as follows:
Decoction liquor passes through the temperature for being heated to corresponding requirements, and the centrifugal type atomizer for being located at dry tower top is supplied to through product pump, utilizes height
Speed centrifugation is atomized into medicinal extract the drop of corresponding requirements, uniformly sprays into drying tower, carries out big face with the hot-air for entering drying tower
Product counter current contact, instantaneously completes drying and moulding, obtains dry powder-shaped product, and the extract dry powder that this technique is made has easily storage
It deposits, transports, the advantages that long shelf-life.Good extract dry powder has good melting, but due to long-term production, in air
Impurity is carried, impurity, which can remain in the duct and enter in drying tower, pollutes extract dry powder, influences product quality, causes to produce
Extract dry powder melting out reduces.
At present for the processing step of pinecone clear cream are as follows: by adding water to cook twice the pinecone, 2~3 hours every time, merge
Decocting liquid, staticly settles and filters, and then takes supernatant to be concentrated into relative density and obtains clear cream for 1.23~1.25, but due to standing
Filtration time is long, and conventional high-temperature concentration is easy to appear breeze, reduces the validity of drug.
Summary of the invention
Goal of the invention: when to solve to prepare pinecone clear cream in the prior art, the production cycle is long, while being easy to appear in product
Breeze reduces the melting and validity of drug, and the invention proposes a kind of method for improving pinecone clear cream melting, Ke Yiyou
Effect lowers the production cycle, while improving the validity of drug, and operating method is simple, and applied widely, condition is easy to control.
Technical solution: to realize the above-mentioned technical purpose, the present invention proposes a kind of method for improving pinecone clear cream melting, packet
Include following steps:
(1) pinecone to be processed is put into heated-air circulation oven 2~3 hours dry in 85~90 degree；
(2) pinecone after drying is decocted, takes supernatant liquid filtering and obtains filtrate, crossed decoction liquor after filtering out precipitating
It is filtered by vacuum by the filter cloth of 400 mesh；
(3) finished product clear cream required for smoke filtrate is completed by heating in vacuum sprinkling concentration.
Preferably, be added in step (2), when decoction it is dry after 1.5~3 times of the pinecone of water decocted.
Specifically, in step (2), the pinecone is added water to cook twice, every time 2~3h, is then combined with decocting liquid and is decocted
Boil liquid.
Wherein, in step (3), heating in vacuum sprinkling concentration includes at least secondary vacuum heating sprinkling concentration, and every level-one is true
After sky heating sprinkling concentration, the clear cream of formation is collected, does not enter the sprinkling concentration of next stage heating in vacuum at the smoke filtrate of clear cream,
In, every level-one vacuum degree is set as -0.05~-0.1MPa, and the aperture of spray head is 80~100 mesh, and temperature is 80~90 DEG C.Smoke filtrate
The overwhelming majority has become clear cream after the sprinkling concentration of level-one heating in vacuum, not at the smoke filtrate of clear cream further across second level
Clear cream is formed after heating in vacuum sprinkling concentration.General secondary vacuum heating sprinkling concentration can be all as clear cream, can basis
Needs of production adjusts vacuum degree, drying temperature and spraying speed and sprays series to adjust required heating in vacuum.
Alternatively embodiment carries out flocculation sedimentation before the filter cloth vacuum filtration of 400 mesh, flocculation sedimentation
Step are as follows: regulating liquid medicine pH is 4~8, stirring, chitosan is added when temperature is 40~60 DEG C, the amount that chitosan is added is every
The pinecone after gram dry corresponds to the chitosan of 0.001~0.1g, and continuing stirring makes whole system become flocculation system, then right
Material is stood；24~48 hours are stood after clarification, supernatant liquid filtering is taken and obtains the decoction liquor after flocculation sedimentation.In recent years,
Some new materials, new technology (flocculation clarification technique) start the purification applied to Chinese medicine extract to replace traditional alcohol precipitation work
Skill, to reduce production cost, shorten the production cycle, especially to the humidity resistance for improving product during preparation produces and stores
Aspect has good effect, guarantees the content of preparation stability and effective component.There are many type of flocculant, there is tannic acid, bright
Glue, 101 fruit juice clarifiers, ZTC clarifying agent, chitosan etc..Chitosan (a kind of Old Region) is that the part of chitin takes off second
Acyl product, and the polysaccharide of unique natural alkalinity found so far, are the natural high molecular substances containing glycosaminoglycan, positively charged
Lotus can settle suspended matter negatively charged in medical fluid (such as cellulose, pigment, tannin, bacterium).And good biocompatibility, and
It can be biodegradable, catabolite is non-toxic, and the research application in field of traditional Chinese medicine pharmacy is very active at present, soaks for Chinese medicine
The flocculation of extract is clarified, can play the role of it is certain isolate and purify, may replace Chinese materia medica preparation produce in alcohol precipitation process, subtract simultaneously
The pollution of few environment.
The utility model has the advantages that compared with prior art, the present invention before decoction by being added in the preparation process of pinecone clear cream
85~90 degree of dry steps, can effectively destroy the molecular structure of pinecone surface waxes, eliminate waxes and dissolve to clear cream
Property influence, by 400 mesh filter clothes be filtered by vacuum, not only greatly shorten stand removal of impurities time, shorten the production cycle.
And effect at low cost is good.Heating in vacuum spray wine enrichment facility not only avoids the breeze occurred in Conventional concentration high temperature, improves
The validity of drug, and operating method is simple, and applied widely, condition is easy to control.
