High efficiency film coating machine mainly used in pharmaceutical and food industries. Featuring mechatronics conforming to the requirement of GMP, it is energy efficient, safe, clean equipment for coating tablets, pills and candies with organic film, water soluble film, slow and controlled release film, sugar film and etc.

Working principle

The tablet cores to be film coated make continual orbital motions within the closed rotating drum under the action of a streamlined guide plate. During the motion, coating medium automatically sprays according to the technological process and rational technological parameters, at the same time hot air is supplied under a negative pressure. The hot air penetrates through the tablet core layers and is discharged from the bottom of the layers, so that the coating medium sprayed on the surface will dry rapidly and evenly, thus forming a solid and smooth surface film.

Features

All the operations, including expansion of PLC module, setting and control of hot air temperature and adjustment of drum speed, are carried out on the touch keys of control panel of computer, and the operating panel is a fully closed light touch film interface which does not influence the cleaning of main machine, thus featuring reliable work, stable performance and conforming to the requirement of GMP.

Under the action of the agitator of steam line guide plate type, the tablet cores are tumbling smoothly and exchanging frequently, thus eliminating the phenomenon of tablet cores to fall from a high place and to collide, solving the problems of broken pieces and chipped edge, and improving the rate of finished products. The narrow surface of the guide plate eliminates the adhesion of coating material on its surface, thus saving the coating material and improving the quality of medicine.

The peristaltic pump with constant pressure variable eliminates the need for a return pipe. The turning radius of the drum varies along with the pressure change. The output slurry and the quantity of slurry sprayed are balanced automatically, thereby stabilizing the effect of atomization, simplifying the spray system, preventing the spray gun from plugging-up, and saving the coating material, moreover the cleaning is simple, and there is no dead corner.

The spray gun specially designed for the film coating machine features even atomization and large coverage of spraying. The universal adjustable spray head makes the cleaning mechanism of spray gun unaffected by charge quantity, so that film coating can proceed continuously, thus reducing the film coating time and saving film coating material.
 

The BGX series microspore film coating machine is a high efficiency, energy-saving, safe, clean, computer-controlled and easy-to-use mechatronics equipment which is used for coating organic film, water soluble film, slow and controlled release film on traditional Chinese and Western tablets and pills (including small pills, water-bindered pills, drip pills, micro pills) and granules, and conforms to the requirement of GMP.

It is a high-tech product solely developed by this factory.

Working principle

The tablet cores to film coated make continuous orbital motion within a closed clean rotating drum under the action of a stream line guide plate. Controlled by computer and according to the optimum technological parameters, they are automatically sprayed with film coating medium, while hot air is supplied under a negative pressure and via a passage between tow layers of mesh plates, the hot air penetrates through the tablet core layers and is discharged form below the drum of double-layer structure, so that the film coating medium sprayed on the surface of tablet cores may dry rapidly and evenly, thereby forming a layer of solid, compact, neat and smooth surface film.

Features

It has all the features of BGX series high efficiency film coating machine.

The film coating drum is with a double layer mesh plate structure, and there is a radial spacer plate between the mesh plates.

It can be used to film coat micropills, small pills, water-bindered pills and drip pills, thus expanding the range of applications of film coating machine.

The BGW series high efficiency poreless film coating machine is a high efficiency, energy-saving, safe, clean, computer-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 small pills, water-bindered pills, drip pills and granulated  pills) and conforms to the requirement of GMP.It is a high-tech product first successfully developed in China by this factory. 

Working principle

The tablet cores (micropills, small  pills or plain tablets) to film coated make continuous complicated orbital motion within a closed clean rotating drum under the action of a stream line guide plate. Controlled by computer and according to the optimum technological parameters, they are automatically sprayed with film coating medium, while hot air is supplied under a 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 film coating medium sprayed on the surface of tablet cores will dry rapidly and evenly, thereby forming a layer of solid, compact, neat and smooth surface film. 

Features

It has all the features of BGB-B series high efficiency film coating machine.

The film coating drum is with a poreless structure, low in energy consumption and 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.

Different materials are equipped with different air paddles. The paddles can be embedded into or taken off from the material.

It has a special purging water discharge unit.
