Description
Technical field
The present invention relates to a kind of equipment that the Chinese medicine concentrated solution is carried out the technology of spray drying treatment and is used for this technology.
Background technology
Use in the more traditional Chinese medicine liquid drying means at present, adopt the drying effect of vacuum drying, lyophilization and heated-air circulation oven undesirable, not only uneven drying even, easily caking, efficient is low and drying time is long, and input and output material all needs manually-operated, vulnerable to pollution, severe operational environment.Boiling-bed drying drying efficiency height, but easily the caking and noise big.The freeze-drying that extensively adopts in pharmacy and food preparation field is to utilize liquid nitrogen to carry out dried under-20 ℃～-160 ℃ low temperature, boulton process is under the pressure of 50～400hPa, be lower than under 35 ℃ the temperature conditions and carry out dried, freeze-drying and boulton process need large-scale equipment, but also be difficult to adopt successive production stage, the production method trouble effort that seems; Simultaneously, after lyophilization or the vacuum lyophilization, necessary additional step such as grind and homogenize and make production process become more loaded down with trivial details again.Spray drying is advanced at present drying equipment; it is to utilize micro-granulating device that solution is made droplet; droplet contacts with the dry wind of relatively-high temperature more then; thereby a kind of method with water evaporates; but existing processes and equipment and technology level are low; sterilization is insufficient in for example whole technology; the dry product bacteria containing amount that causes medicinal liquid and finally make is too high; because the medicinal liquid viscosity is inhomogeneous, cause spraying unstable, have a strong impact on the quality of dry finished product; and the finished product collection rate is low; waste greatly etc., also be difficult to the higher medicinal liquid of concentration of treatment, and dry tenacity is low; returning charge is bigger.
Summary of the invention
Purpose of the present invention provide in order to overcome above-mentioned the deficiencies in the prior art just a kind of occupation of land less, energy consumption is low, dry tenacity is big, efficient is high, finished product does not lump, the sealing of recovery rate height, whole process of production carry out, can satisfy domestic and international GMP to the code requirement of pharmaceutical production, free from environmental pollution, and can be to the dry omnidistance Chinese medicine concentrated solution drying process with atomizing of control automatically and the equipment that is used for this technology carried out.
The objective of the invention is to be achieved through the following technical solutions.
Chinese medicine concentrated solution drying process with atomizing, its technological process is: 1., need be exsiccant concentrated medicament add feed tank internal heating, stirring, and circulate in the closed circuit of between by feed tank, solution feed pump and connecting pipe, forming, limit heating, the circulation of stirring limit, carrying out homogenizing and the constant pretreatment of temperature of medicinal liquid, and the follow-up flow that enters spray drying tower of stable solution feed pump; 2., with pretreated concentrated medicament quantitative with through filtration, hot-air after the heat treated sends in the spray drying tower simultaneously, concentrated medicament, fully contact with high-temperature hot air, and rapid draing is become granule by the high speed rotating atomisation by aerosol apparatus; 3., dried granule is entered separation, the collection that cyclone separator carries out final products by air conveying.
