Automatic pharmaceutical film coating machine for
tablet
The product
is an ideal film coating machine in current pharmaceutical industry
at home. It can be applied in many fields like pharmacy, food,
biological products, etc.. The machine is particularly applied to
coat tablets, pills, and candies with all kinds of organic or
water-soluble film. As a film coating machine, it is widely applied
in pharmacy and food industry. Compared with its similar products,
this machine acquires distinct
advantages:
1. PLC and temperature module controlling
system with the touch screen produced by Siemens Germany are
applied to provide picture displaying, convenient operation,
energy-efficiency, cleanliness and safety, and convenient cleaning,
which meets the standard of GMP.
2. Components, which drugs are exposed to, such as high
efficiency film coating mainframe, high efficiency hot air filter,
dust removal fan and spray device, are all made of imported
stainless steel of good quality.
3. The procedures are all controlled by PLC touch screen,
automatically or manually.
4. Coating is processed in totally closed environment to
prevent dust and slurry from spilling. The surface of box is
polished and its light pollution is eliminated.
5. The driver system applies explosion-proof
decelerating motor and chain-wheel transmission device, which
can make frequency conversion continuously variable.
6. High efficiency hot air filter can directly capture air
from outside, heat the air after primary, intermediated and high
efficiency filter, and then provide the air for the mainframe. The
air can meet the standard of **0,**0 class cleanliness. Dust
removal fan can exhaust air to the outside to avoid the influence
on central air-conditioning and to save energy.
7. Spray gun is the WA***1 spray gun imported from Japan of
good atomization, non-clogging nozzle, adjustable spray volume and
angle, and simple structure which is convenient to
clean.
Currently,
the machine has relatively large market and good prospect at home.
It has been applied by lots of factories for many times and passed
the inspection of GMP
successfully.
During coating, the machine ensures no flying
dust or splashing liquid. In this case, it can improve working
environment and avoid cross contamination. Besides, the machine can
coat tablets through simple techniques so that coating time is
drastically shortened and efficiency is much higher. It adopts new
micro-computer temperature and negative pressure control system,
touch screen for displaying and control and is programmable. These
devices can work together to automatically adjust flow,
negative pressure, air , air exhaust, temperature, rotating
speed and some other technical parameters. They also make SOP
edition digital so that the machine can produce in batches in the
same technical parameters. Therefore, there is nearly no difference
between products of different batches. The machine also
additionally functions to store and print data. Its tens of program
for automatic coating can be modified at any time during operation.
In addition, printing device can be customized to record technical
parameters and process flow of every batch. Users can also
batch number or drug code as needed.
1.Performance and
features
1)Automatic
online cleaning system (optional): high-pressure spraying guns are
installed at both internal and external coating pot and cleaning
sprayers at air exhaust port and hot air port. They can rotate in
**0° for no dead corners, more conveniently and simpler
cleaning.
2)High-end
spraying gun conforms to GMP and coating techniques strictly. Its a
special spraying gun made of stainless steel. It can be used
simply, dismantled without other tools and controlled flexibly. It
features no leak, no clog, controllable flow and angle, uniform
atomization, large spraying area and excipients
saving.
3)The
machine also includes a mechanical device for its coating a small
amount of material in a large pot. For example, the **0 coating
machine can coat at least ****0 uncoated tablets. Through the
device adjustment, the machine can coat smaller amount of uncoated
tablets in large pot without wasting excipients and widen the
machines application.
2.Filtering
hot air cabinet
Air is
inhaled by centrifugal fan and achieves **0,**0 class cleanness by
primary, medium and high filtering. Then heat exchanger (steam or
electricity) will blow the air into machine roller. Besides, a
vibration absorbing device is equipped for this process. And a
primary air filtering device is installed at the air inhale
port.
3.Dust
removing and air exhausting
cabinet.
The cabinet
works mainly to exhaust air in machine roller and collect dust to
keep working zone in negative pressure and dust-free. It is also
equipped with a vibration-absorption device. A backflow preventive
device is installed at the air exhaust port. It can close the port
before machine shutdown and prevent waste air in pipeline from
flowing back. The cabinet also can be set and timed to automatic
remove dust by vibration.
4.Insulation
mixing barrel
Insulation
mixing barrel is heated electrically. Its pneumatic mixing device
is powered by compressed air for stable rotation, stepless speed
control and uniform mixing. The temperature can be kept within room
temperature to *0°C. It features convenient, safe and reliable
operation. In addition, it is made of stainless steel and
mirror-polished on its internal and external
surfaces.
5.Basic
working principle
Uncoated
tablets move complexly in a clean and closed rotary roller. They
overturn fluently and change position frequently. The coating
medium is mixed in insulation mixing barrel and sprayed to uncoated
tablets by spraying gun through peristaltic pump. Simultaneously,
negative pressure forces **0,**0 clean hot air to blow over
uncoated tablets and be exhausted through the bottom screen. Thus
coating medium can dry and form steady, dense and smooth film on
tablet surface quickly. The whole process is controlled by PLC and
finished automatically.
