Description
Technical field
This utility model belongs to Chinese crude drug process equipment field, is specifically related to a kind of Chinese crude drug low-temperature drying equipment.
Background technology
The production of Chinese medicine material and processing have had the history of thousand of years, and the drying process used is mainly nature
Drying, owing to its floor space is big, arid cycle, length was low with production efficiency, it is clear that can not meet modernization Chinese medicine industrial
Need, then, be developed a lot of drying equipment, then, be developed many drying equipments, as the most wide variety of
Hot air drier, turnover plate type drying machine, mesh-belt drier, horizontal grooved vibration fluidizing drier and horizontal circle motion oscillations stream
Fluidized dryers etc., these equipment, owing to have employed air-flow technology, correspondingly improve baking temperature and speed, with the side of drying naturally
Method has compared great progress, it also avoid nature simultaneously and dries the problems such as climate impact.But, tend to be neglected by people
Problem slightly is: the formula of Chinese medicine is that the medical material that forefathers apply nature to dry repeatedly is being tested, repeatedly summed up experience and lessons
On the basis of obtain, its various medical materials include effective ingredient number, all kinds of medical material relative scale size the most exquisite.
27 kinds of prepared slices of Chinese crude drugs are used hot air drying laboratory table to carry out drying property experiment by current domestic expert, and with purple
The index components of the prepared slices of Chinese crude drugs before and after experiment is detected by the methods such as outer optical spectroscopy, high pressure lipuid chromatography (HPLC).From experiment number
According to showing: although the temperature of charge that the temperature used during the experiment of part medical material still allows less than existing factory drying process, but
Its index components has received the biggest loss, provides some experimental data therein to find out from expert: Herba Menthae, Radix Scrophulariae use 70
During DEG C hot air drying, although its highest material temperature only has 68.5 DEG C and 67 DEG C, its index components is lost the most completely；Radix Trichosanthis uses 70
During DEG C hot air drying, its index components have lost more than 2/3；When Rhizoma Curcumae, the Radix Paeoniae Alba use 70 DEG C 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 DEG C, its index components has lost 59.2%；
When Radix Et Rhizoma Rhei, Radix Saposhnikoviae use less than 80 DEG C alternating temperature hot air dryings, although the highest material temperature only 70.2 DEG C, its index components have lost
More than 40%.Therefore, the finite element in Chinese crude drug is destroyed by modern hot air drying equipment, and causing Chinese crude drug is not have
Use value.
Utility model content
This utility model is intended to provide a kind of Chinese crude drug low-temperature drying equipment, to solve current hot air drying equipment to destruction
The problem of the finite element in Chinese crude drug.
A kind of Chinese crude drug low-temperature drying equipment in this programme, including hothouse, refrigeration machine, condenser, described hothouse
For cylindrical shape, being provided with the rotary shaft being vertically arranged in described hothouse, described rotary shaft is provided with multilamellar for placing Chinese crude drug
Dividing plate, described diaphragm internal is provided with heater strip, is provided with the power line being connected with heater strip, described refrigeration machine in described rotary shaft
Being all connected with hothouse with condenser and be positioned at outside hothouse, described condenser is also associated with vacuum pump.
Operation principle of the present utility model: want owing to reaching balance between three kinds of phases (solid-state, liquid and gaseous state) of water
Having certain condition, along with the reduction of pressure, the boiling point of water can be more and more lower, when pressure reaches certain value, and boiling point and freezing point
Overlap.Under Chinese crude drug (-10 ~-75 DEG C) at a lower temperature, its interior moisture is frozen into solid-state, then at high vacuum
Under (0.133 ~ 133pa), wherein moisture can be converted into gaseous state without liquid, will not be in Chinese crude drug during this
The effective ingredient in portion produces and destroys, and keeps the integrity of cell wall so that the effective ingredient of Chinese crude drug retains more.At this programme
In, hothouse is designed as cylindrical shape, while saving occupation of land space, also helps and allows whole hothouse reach vacuum faster
State, and the raising and lowering of temperature all can spread rapider.Rotary shaft be by hothouse outside motor drive, turn
In the rotation process of moving axis, Chinese crude drug is positioned on dividing plate, its temperature can be allowed to be kept as more uniform.Vacuum pump will be for doing
Dry room is evacuated environment, is dried room pressure and declines, and the moisture boiling point in Chinese crude drug reduces, and at this moment opens refrigeration machine, will be dry
The temperature of dry indoor declines so that the moisture in Chinese crude drug is solidified as ice.It is energized to power line again, heater strip heating power, make
Chinese crude drug temperature on dividing plate rises, the most at a lower temperature, it is possible to allow ice directly rise Huawei's steam, steam along
The pipeline of evacuation, is drawn out of hothouse so that hothouse humidity reduces, and the steam extracted out is in the effect of condenser
Under, liquid can be condensed into again, this partially liq may be used for follow-up operation.
The beneficial effects of the utility model: the moisture in Chinese crude drug, mainly by refrigeration machine, is solidified by this utility model
For ice, then by hothouse is bled, make to be dried room pressure and decline so that the boiling point of moisture reduces, and this is up to needs somewhat
Heating Chinese medicine material, just can allow ice directly rise Huawei's steam at a lower temperature, and after steam is drawn out of, at the work of condenser
Being condensed into water under with, may be used for follow-up processing, improve water utilization rate, this programme can be in relatively low temperature
Lower realize Chinese crude drug be dried, the cell wall of Chinese crude drug will not be destroyed, be effectively retained the effective ingredient of Chinese crude drug so that Chinese medicine
The drug effect of material is more preferable, is worth more preferably.
Further, described hothouse includes that annular perisporium, described annular perisporium are provided with observation window, described observation window and ring
The junction of shape perisporium is provided with sealant, such is advantageous in that the drying regime that can be easy to observe Chinese crude drug, and in order to keep
Vacuum tightness environment in hothouse, each outlet needs at hothouse seal so that it is air tight, so sealant
Arrange to allow and keep good seal between observation window and annular perisporium.
Further, described dividing plate is provided with organizes air-vent more, and air-vent is conducive to the rapid conduction of heat so that Chinese crude drug
It is dried the rapidest.
Further, the aperture of described air-vent is 0.3 ~ 0.5cm, and when aperture is less, temperature conductivity is bad, it is impossible to realize
Well temperature transfer, when aperture is bigger, the Chinese crude drug that dividing plate can be placed is limited, it is impossible to place the Chinese crude drug that size is less, warp
Practice, most of Chinese crude drug, when 0.3 ~ 0.5cm, while ensureing good heat conductivity, can be placed in aperture.
Further, described dividing plate outer rim is provided with the baffle plate preventing Chinese crude drug from dropping, owing to dividing plate is in rotation process, and Chinese medicine
Material can produce the centrifugal force outwards dished out, and baffle plate is possible to prevent Chinese crude drug to drop out outside dividing plate.
