2. Imported PLC, HMI, and touch screen are applied to meet requirements of variable pharmacy technology with advantages of stable operation and performance. They also comply with the standards of GMP.
3. Under the force of linear deflector and mixer, tablets reverse fluently, exchange frequently and will not be impacted after falling down from a swell so that tablets keep intact.
4. Peristaltic pump applies continuous variable frequency conversion. The speed can be adjusted within a range of 0~280 r/min to eliminate defects that resistive speed regulation and voltage speed regulation are not stable, potentiometer is breakable easily, and that rotating speed cannot reach zero because of mechanical speed regulation. Lastly, flame-proof and explosion-proof motor is equipped to fully meet the explosion-proof requirements with stable atomization performance. Spraying system can prevent the spray gun from blockage and can be cleaned conveniently without any dead end.
5. The spray gun acquires advantages of evenly atomization and large spray surface. Besides, the adjustable sprayer will not be influenced by liquid volume.
6. The mixer combines mechanism and electricity in one to avoid chaotic layout of wires and air tubes and to be cleaned more easily.
7. It is newly designed that the negative pressure inside the film coating pan can be measured and adjusted automatically to improve the coating quality but save energy.
8. Hot air blower and ventilator are equipped with shockproof and silencing equipment to lower the operation noise of the complete machine and to not harm health of operator.
9. Temperature value is displayed and temperature can be controlled.
10. The function of cleaning guns to avoid blockage is acquired.

About BG-400
1. Production capacity: 400Kg end product per pan (the same with sugar coating and organic film coating).
Note: The film coating cylinder volume for material is about 400L, counted by the volume between the bottom and the lower edge of cylinder. However, practical operating volume is 350-400L, while the maximum density of material is 1.0Kg/L. Thus, the final weight can be counted to 400Kg.

2. The machine can film Chinese and Western tablets, pills, and candies with organic film, water soluble film and sugar coating. The coating quality complies with pharmacopoeia of China. The machine has served for hundreds companies to produce several hundred medicines complying with the requirements of pharmacy.
3. The equipment surfaces are all treated.
1) The film coating roller and mixer contacting with tablets are made from stainless steel of good quality, such as AISJ316L, etc.. Internal and external surface of the roller, and the mixer have all been treated with mirror finish with Ra ≥ 1.6. Generally, Ra = 0.8.
2) Other equipments are made from stainless steel and comply with the standards of GMP. Film coating operates in a absolutely closed environment. The complete machine with a stainless steel dustcoat is closed and acquires advantages of convenient cleaning, good sealing, no leaking and no dust.
3) The external surface of the complete machine is treated with matt and decorated with horizontal stripes.
4. About the mainframe:
1) The speed of roller can be adjusted within 2-16 r/min with error of ± 0.5r/min
2) The internal and external surface of the pan is smooth, and the orifice and sieve are all flat without glitch. The bucket is treated with mirror finish internally and externally to be smoothly connected without any dead end.
5. Controlling system
1) FBE-40MC PLC produced by FACON, Taiwan and Pro-face touch screen produced by Digitac are applied so that almost all operations can be finished on the touch screen.
2) Functions of remote monitoring and access controlling can be equipped.
3) The system components are all produced by famous manufacturers at home and abroad with strong anti-interference ability to make the system operate stably and steadily.
4) The power cabinet separates from the mainframe.
6. Others:
1) Electrical safety performance complies with the regulations of GB5226.1.
a) Electrical component controlling and power circuit insulation cathode should not be less than 1MW.
b) Electricity consists of external electrical components and controlling and a voltage test when the power circuit reach 100V AC, 50Hz.
2) The film coating roller operates stably with noise no more than 65Db (A)
3) The motor applied in ventilating and infusing equipments should be explosion proof. And the fan blades are made from aluminum alloy which is explosion proof too.

Innovative Technology
The invention, discovery and innovation mainly reflect in the following aspects:
I. Spraying system equipment:

• 1. The imported spray gun is practical and flexible since its spray shape, flow, and angle can be adjusted;
• 2. Moving baffle is set in the ventilator, which offsets the defect that film coating material and thermal energy are taken away during ventilation when the substrates in the pan are more or less.
• 3. The film coating machine is equipped with explosion-proof flashlight which is convenient for the detection of sprayed granule size and tablet film quality.
• 4. Remote controllable and explosion-proof peristaltic pump is connected with PLC of the mainframe. Value of flow and rotating speed display and can be adjusted by man-machine dialogue on the touch screen. Variable-frequency speed control is applied so that the speed can be adjusted to the smallest scale when the rotating speed and flow are all at zero. Furthermore, flow can be controlled accurately, stably and conveniently and inconvenience and inaccuracy of off-site operation can be eliminated since the value of flow can be displayed digitally on the touch screen. Next, explosion-proof motor is equipped to make the machine comply with standards of GMP. Lastly, the reverse switch set on the touch screen can make excess film coating material flow back to the roller and reduce the material wasting. Therefore, the peristaltic pump is the most ideal.

II. Hot air blower and ventilator are equipped with shock-proof and silencing equipments to lower the operating noise obviously and protect the health of operators.
III. PLC is applied to design HMI and screen displaying and operating system. Operators can set programs and adjust and control variable parameters during film coating through human-machine dialogue box. Therefore, automatic operation can be fulfilled throughout the process.
IV. The mixer combines mechanism and electricity in one to avoid chaotic layout of wires and air tubes and to be cleaned more easily.
