Description
Technical field
The present invention relates to pharmaceutical engineering equipment technical fields, and in particular to a kind of minor diameter pill drying machine and drying side
Method.
Background technique
Ethnic drug is China various nationalities during resisting with disease, maintaining national existence procreation, with respective life
Environment, natural resources, national culture, religious belief, the theory and practice of this traditional ethnic minority medicine etc. are foundation, and foundation has this
The drug that the medicine systems of national characters use.It from the picking of medicinal material, processes to production and processing and has respective distinctive feature, use
Natural conditions utilize natural method, guarantee product ecosystem and environmental protection.
Pill refers to that medicine materical crude slice fine powder or extract add spherical shape or spherical system made of suitable binder or other auxiliary materials
Agent is broadly divided into the water-bindered pill, honeyed bolus, water-honeyed pill, condensed pill, starched pill, wax-wrapped pill etc. by auxiliary material difference.It is dry as pill can not or
One of scarce operating unit has large effect to pill quality and clinical efficacy.The dry moisture referred in pill is heated
The process being removed, degree of drying and speed are by temperature, vacuum degree, drying time, drying equipment and technique and material itself
The influence of the factors such as structure, the efficiency of pill drying process heat and mass, the final formation for influencing pill drying quality.By complete
The practical investigation of more anaesthetic pharmacy corporations of state finds that there are more problems for the drying unit in anaesthetic pill production process.Such as
Arid cycle is long, and medicine pill drying time, some kinds were even more than 72h generally in 9h or more；And need low temperature
Dry, temperature, which crosses meeting height, causes fragrant ingredient, heat-sensitive ingredients loss big, pharmaceutical effectiveness decline；Drying process falls behind, equipment
Lack innovation, currently, mainly dry using low temperature drying chamber static state, technology controlling and process is extensive；Energy consumption for drying is high, and heat utilization efficiency is low；Matter
Amount controlled level is low, and pill quality evaluation lacks systems approach and evaluation means；Pill drying process lacks deep mechanism
Often is there is crust, splits phenomena such as ball, false drying, male and female face in research after dry.
Pill is mostly compound, and chemical component multiplicity, constitution system are complicated, and the superiority and inferiority of quality directly affects the matter of finished product
Amount.Herein with reference in the quality evaluation of " Chinese Pharmacopoeia " pill to character, moisture, leach time limit, microorganism, content etc.
It is required that in conjunction with other field sensory evaluation, physical evaluation, Chemical Evaluation etc. is closed as reference, overall merit, the matter for controlling product
Amount.
In drying process, holds material mode and directly determine state of the dried material in drier, whether transported by material
It is dynamic to be divided into dynamic and static state.The dry contact probability that pill and thermal medium can be improved of dynamic, can augmentation of heat transfer efficiency, accelerate dry
It is dry.The anaesthetic water-bindered pill is to make that adhesive is general to be made the pill of quality loosely of water by powder drug, should not use whizzer,
Bipyramid rotary dryer, boiled bed drying machine etc..Since the production of the anaesthetic water-bindered pill does not use any adhesive, if applied to pill
Excessive exciting force or unsuitable mode of vibration may cause pill and scatter mistake type.After uneven heating is even in the drying process
Contraction is generated, if being subject to exciting force again, will lead to pill cracking, therefore anaesthetic pill generally uses static state to hold material or slowly even
Speed is stirred, draughty drying mode.Anaesthetic water-bindered pill agent has the characteristics that multi-component, and contains heat-sensitive ingredients mostly,
It is easy that effective component is made to decompose or be lost under high temperature, therefore, drying temperature cannot be too high, and there are one in the selection of drying means
Fixed limitation.The requirement of low temperature drying is affected to drying efficiency, and temperature is as pill constant rate drying period heat and mass
One of main drive reduces temperature and the rate of drying in the stage is substantially reduced, so that most medicine pills enterprise exists
It is time-consuming up to 24~48h, portion when carrying out industrial production using 50~60 DEG C of hot air circulation drying ovens or drying chamber are dry to pill
Divide kind even in 48h or more.Meanwhile in pill dry using baking oven or drying chamber, the drying process of pill be it is static, be
Prevent because uneven heating it is even caused by pill deformation, male and female face and other issues, generally require manually turn over to pill,
Human cost is increased, therefore, the production capacity deficiency of the drying process section of pill becomes the bottleneck that pharmacy corporation expands the scale of production
Problem.For the raising of the low temperature hot-air drying technology thermal efficiency, from rational design air current composition and tail heat recovery system can be increased
Etc. improve.Reasonable air current composition should be such that hot-air and material comes into full contact with to propose high heat and mass transfer efficiency, rationally
The temperature and humidity gradient that disposition hot-air is formed in the drying process, forms the cascade utilization of energy.Hot-air is in the drying process
Reasonable heat recovery is carried out while sufficiently taking away moisture in pill, to improve the thermal efficiency.And medicine pill is solved in baking oven
Or the problem that static dry zone comes in drying chamber, improvement can be designed to the carrying form of material in drying equipment, such as with machinery
The vibrated bed of driving method, the revolution forms such as bipyramid cylinder and rotatingcylindrical drum, can realize that pill is presented in the drying process
The state of movement can not only be such that material more uniformly contacts with thermal medium, and pill can be right along round as a ball move of drier wall surface
Pill further progress moulding improves presentation quality.
