Tedious process, the use of syrup is also unfavorable for that diabeticss are taken.
Content of the invention
It is an object of the invention to overcoming the deficiencies in the prior art, there is provided a kind of medicine pill coating treating diabetes
Technique, its operation is simple, it is easy to accomplish, low cost, after coating pill rounding uniformly, weightening less, gloss and color and luster good, can increase
The compliance of patient.
The present invention solves the above problems and is achieved through the following technical solutions: a kind of medicine pill bag treating diabetes
Clothing technique, comprises the following steps:
In step one, the coating pan that the addition of plain ball is obliquely installed；
Step 2, startup coating pan, and add the ethanol solution profit of concentration of volume percent 10%～60% into coating pan
Wet softening element ball surface；
Step 3, after plain ball moistened surface softens, add in it plain ball gross weight 0.5%～1.5% into coating pan
Pulvis Talci；
Step 4, after Pulvis Talci after plain ball surface distributed is uniform, add in it plain ball gross weight 0.5% into coating pan
～1.2% medicinal charcoal；
Step 5, fully stick to behind pill surface after medicinal charcoal, add concentration of volume percent again into coating pan
10%～60% ethanol solution moistening is coated on medicinal layer of charcoal and the Talcum bisque on plain ball surface；
After step 6, the medicinal layer of charcoal after plain ball surface and Talcum bisque moistening, then add plain ball in it into coating pan
The medicinal charcoal of gross weight 0.1%～0.2%, then keeps coating pan to obtain coated pill after being rotated further polishing 2～4h；
Step 7, by be obtained coated pill be dried.Wherein, medicinal charcoal adopts the plant of the pure natural such as coconut husk, shell, timber
Activation furnace gets through pyrolysis, is coated as main coating material with it, safe without toxic side effect, will not give
Patient increases burden and is used, and because using the use that completely avoid syrup during its coating, so particularly suitable
In diabeticss.
In the present invention, Pulvis Talci mainly has two effects, and an effect is anti-stick, and another effect is filling pill surface,
Make pill smooth surface smooth, reduce pill in follow-up frictional force when rolling bag charcoal clothing, improve mobility of particle.The present invention
Through twice plus ethanol solution operation and twice plus medicinal charcoal operation during application, wherein, add ethanol solution for the first time and there are two
Effect, one is to reduce the too strong viscosity of pill, prevents adhesion between pill, two is to adhere on plain ball for the ease of Pulvis Talci；The
Secondary addition ethanol solution be in order that in coating pan pill during rolling friction, Talcum bisque and medicinal layer of charcoal can be more
The adhesion of medicinal charcoal when closely adhering to, and being easy to add medicinal charcoal again.The present invention is for the first time plus medicinal charcoal is in order in Talcum
Charcoal clothing is formed on bisque, adds the pill after medicinal charcoal can make coating for second more smooth.The present invention limits talcous use
Measure 0.5%～1.5% for ball gross weight plain in coating pan, after adding Pulvis Talci, adhesion between pill, and can be all in coating pan
Even smoothly roll.The present invention limit for the first time plus during medicinal charcoal medicinal charcoal consumption as coating pan in element ball gross weight 0.5%～
1.2%, it forms one layer of uniform charcoal clothing after can guarantee that interpolation medicinal charcoal on the Talcum layer of pill.
The gradient of coating pan influences whether the upset of pill, and gradient is too small or excessive, and pill all cannot overturn, and does not have
Have through effectively overturning, the pill after coating just can not reach smooth effect, and the folder of coating pan and horizontal plane
Also result in pill when angle is larger and spill coating pan.In order to ensure that in coating pan, pill can normally overturn and prevent pill from splashing,
Further, described coating pan and the angle of horizontal plane are 35 °～45 °.
If the rotating speed of coating pan is too low, the movement velocity of pill is low, frictional force and impact force that in coating pan, pill is subject to
All less, the charcoal clothing layer of bag pill out not only not consolidation, and pill can also cannot be carried out effectively rolling, pill each
Angle does not have uniform stressed and adhesion adjuvant, and leads to rough whole, has no gloss, color and luster, or even also piebaldism；If sugar-coat
Pot rotating speed excessive, the frictional force that in coating pan, pill is subject to is all larger with impact force, pill as eccentricity excessive and with
The rotation of coating pan rotates together, is not also effectively rolled, and bag pill out does not equally reach the effect of smooth rounding
Really.In order to ensure that in coating pan, pill effectively rolls, further, the rotating speed of described coating pan is 20～46r/min.
Although Pulvis Talci has no toxic side effect, it is the adjuvant having no therapeutical effect, in order to control making of cost and patient
Consumption, further, the talcous weight adding in described step 3 is 0.7% of plain ball gross weight in coating pan.
Although medicinal charcoal also has no toxic side effect, it is also the adjuvant having no therapeutical effect, in order to control cost and patient
Usage amount, further, the weight adding medicinal charcoal in described step 4 is 0.75% of plain ball gross weight in coating pan.
Further, the weight adding medicinal charcoal in described step 6 is 0.15% of plain ball gross weight in coating pan.
Further, in described step 7, coated pill drying is carried out in microwave vacuum dryer, and wherein, microwave vacuum is done
The design temperature of dry machine is 65～80 DEG C, and vacuum is all higher than -0.07mpa, is dried and is less than 9% to coated pill water content.Existing
The drying commonly used heated-air circulation oven drying air fan circulation air supply mode of pill, i.e. wind regime when technology prepares coated pill
By circulation air supply motor drive, via heater heating, the hot blast sent via air channel to drying baker interior room, then will use after
Air sucks air channel becomes wind regime recirculation, and heating uses, so repeatedly.The shortcoming of this drying means is: heat is from pill
Outside gradually internally conduct heat to reach dry purpose, slow drying speed, pill internal/external heating is uneven, is easily caused drying
Pill splits ball, the outward appearance of impact pill afterwards, and needs operator periodically to turn over medicine, high labor intensive, and quality index is unstable.This
Bright dry run adopts microwave vacuum dryer, and drying process, product quality are more controllable, have that uniform drying is quick, sterilization,
The advantages of efficient energy-saving.
Further, the concentration of volume percent of the ethanol solution adding in described step 2 and step 5 is 20%, institute
The weight stating the ethanol solution adding in step 2 is 3% of plain ball gross weight in coating pan, the ethanol adding in described step 5
The weight of solution is 1.75% of plain ball gross weight in coating pan.The present invention limit in step 2 add concentration of volume percent as
The consumption of 20% ethanol solution is 3% of plain ball gross weight in coating pan, is avoided that plain ball fails enough moistenings and softens and lead
The medicinal charcoal that adds in Pulvis Talci that cause can not add in the uniform adhesion step 3 of pill surface and step 4 is it is ensured that bag charcoal clothing
The uniformity, and be avoided that plain ball to overbate and the phenomenon such as viscous ball or even pill deformation occur；The present invention limits in step 5
The consumption adding the ethanol solution that concentration of volume percent is 20% is 1.75% of plain ball gross weight in coating pan, and it is used for moistening
Talcum bisque and medicinal layer of charcoal, for adding medicinal charcoal to provide condition in step 6, and are avoided that Talcum bisque and medicinal layer of charcoal mistake
Degree softens and the phenomenon such as viscous ball or even pill deformation occurs.
In sum, the method have the advantages that (1) prior art carrys out moistening ball frequently with water often in coating
Medicine, but because treat diabetes the universal viscosity of medicine pill stronger, meet water after viscosity increase, if add water moistening when add water very little not
Soften pill surface enough to moistening, if the too many water that adds water can immerse inside pill, the tactile water layer viscosity of pill can increase, and therefore can
Need substantial amounts of dried powder to fill and anti-stick, otherwise coatings will be led to coarse because of inter-adhesive between pill and not
Smooth, and the utilization of a large amount of dried powder, also can affect the disintegrate of pill, for this problem, the present invention takes and uses volume basis
Carry out moistening pill than the ethanol solution for 10% ~ 60%, ethanol solution viscosity itself is less, can solve and meet asking of water viscosity increase
Topic, also greatly reduces the consumption of each adjuvant.Moistening pill is carried out according to water, the used in amounts of water is more than during present invention application
8%, Pulvis Talci need to be more than 2%, and the used in amounts of medicinal charcoal is more than 1.5%, and adopts concentration of volume percent 10%～60% ethanol solution
Carry out moistening pill, talcous consumption can lower 65%, and the consumption of medicinal charcoal can reduce by 40%, and the consumption of ethanol solution can only account for
The 59% of water consumption.
(2) after being dried for traditional art for coating coating, coatings peeling easy to crack, or even there is splitting the problem of ball, this
Number of times and each consumption that invention is added by strict control wetting agent (ethanol solution of the 10% ~ 60% of indication of the present invention),
To control the content of wetting agent in coated pill, it is to avoid when being dried because of the evaporation of wetting agent, pill significantly shrinks and occur
Charcoal clothing layer cracking even splits the phenomenon of ball it is ensured that the smooth degree of coated pill, also greatly shortens coated pill simultaneously
Drying time, that is, save the energy and also shortened the production cycle.
(3) present invention is directed to the micro-judgment that traditional art for coating is based entirely on technical staff, arbitrarily adds supplementary product consumption,
Lead to supplementary product consumption big, and the big problem of coating quality difference between different batches, will be each auxiliary on the premise of ensureing coating effect
