Negative Pressure Controlled Efficient Coating Machine

It is used for coating sugar, organic film, water soluble film, slow and controlled release film on tablets and pills.  

Application

BGW-B Series High-efficiency Plreless Filmcoating Machine is a high-efficiency,energy-saving, safe, clean, computer PLC controlled and mechatronics equipment which is used for coating sugar, organic film, water soluble film, slow and controlled release film on traditional Chinese and Western tablets and pills(including micropills, small pills, water-bindered pills, drip pills and granulated pills) and conforms to the requirement of GMP. It is a high-tech product first independently researched and developed in China by our factory which can conduct negative pressure automatic control in cavity.

Working Principle

The table cores to be filmcoated make continuous complicated orbital motion within a closed rotating drum under the action of a streamline stirrer. Controlled by computer and according to the technological process and reasonabe technological parameters. they are automatically sprayed with filmcoating medium while hot air under a controlled negative pressure is led in from one side of an air distributing pipe at the center of the drum, clean hot air penetrates through the tablet core layers and is discharged after being collected to the other side of the air distributing pipe by a pore duckbill-shaped(or oval)air paddle embedded in the tablet core layers, so that the filmcoating medium sprayed on the surface of tablet cores will dry rapidly and evenly, therby forming a layer of lolid, compact, neat and smooth surface film.

Features:

It has all the features of BG-D Series High-efficiency Filmcoating Machine. The filmcoating drum is with a poreless structure. Different air paddles are equipped for different materials. Above 0.6mm tablet coating, versatile in use. It has a specially structured air distributing system, and the air intake and exhaust pipes can be interchanged according to the needs. The air paddles can be embedded into or taken off from the material according to technological needs. It has an automatic water discharge unit. It has the functions of negative pressure and automatic control, which can save filmcoating material and energy. The machine can equipped with automatically cleanness system that can realize many cleaning methods, omnibearing position clean.
